    Cancer-related fatigue (CRF) significantly interferes with usual functioning because of the distressing sense of physical, emotional, and cognitive exhaustion. Assessment of CRF is important and should be performed during the initial cancer diagnosis, throughout cancer treatment, and after treatment using a fatigue scoring scale (mild-severe). The general approach to CRF management applies to cancer survivors at all fatigue levels and includes education, counseling, and other strategies. Nonpharmacologic interventions include psychosocial interventions, exercise, yoga, physically based therapy, dietary management, and sleep therapy. Pharmacologic interventions include psychostimulants. Antidepressants may also benefit when CRF is accompanied by depression. Copyright © 2017 Elsevier Inc. All rights reserved.

    Fatigue is one of the most common and distressing side effects of cancer and its treatment, and may persist for years after treatment completion in otherwise healthy survivors. Cancer-related fatigue causes disruption in all aspects of quality of life and may be a risk factor for reduced survival. The prevalence and course of fatigue in cancer patients has been well characterized, and there is growing understanding of underlying biological mechanisms. Inflammation has emerged as a key biological pathway for cancer-related fatigue, with studies documenting links between markers of inflammation and fatigue before, during, and particularly after treatment. There is considerable variability in the experience of cancer-related fatigue that is not explained by disease- or treatment-related characteristics, suggesting that host factors may play an important role in the development and persistence of this symptom. Indeed, longitudinal studies have begun to identify genetic, biological, psychosocial, and behavioral risk factors for cancer-related fatigue. Given the multi-factorial nature of cancer-related fatigue, a variety of intervention approaches have been examined in randomized controlled trials, including physical activity, psychosocial, mind-body, and pharmacological treatments. Although there is currently no gold standard for treating fatigue, several of these approaches have shown beneficial effects and can be recommended to patients. This report provides a state of the science review of mechanisms, risk factors, and interventions for cancer-related fatigue, with a focus on recent longitudinal studies and randomized trials that have targeted fatigued patients.

    In July 2010, at the Muscle Fatigue Meeting, I presented an overview of Chronic Fatigue Syndrome and Cancer Related Fatigue, emphasizing a critical interpretation of the potential association between Chronic Fatigue Syndrome and Cancer Related Fatigue and a newly discovered retrovirus: Xenotropic Murine Related Virus. Since this association was hotly debated at that time, I suggested at the Meeting that it was wrong and most likely due to the identification of the wrong virus culprit. Today, 20 months after the Meeting, the first part of our prediction has turned out to be correct, as Xenotropic Murine Related Virus was shown to be a laboratory-created artefact. Still, the potential association of fatigue-syndromes with an infection (most likely viral) is sustained by a plethora of evidence and this overview will initially summarize data suggesting prior viral infection(s). The principal hypothesized mechanisms for both peripheral and central Chronic Fatigue Syndrome/Cancer Related Fatigue will be then summarized, also indicating plausible associations and triggering factors. All evidence accrued so far suggests that further research work should be performed in this interesting area and in order to identify an infectious agent for Chronic Fatigue Syndrome/Cancer Related Fatigue. One candidate RNA virus, Micro-Foci inducing Virus, will be described in this overview. Copyright © 2012 Elsevier B.V. All rights reserved.

    Fatigue is one of the most common adverse effects of cancer that might persist for years after treatment completion in otherwise healthy survivors. Cancer-related fatigue causes disruption in all aspects of quality of life and might be a risk factor of reduced survival. The prevalence and course of fatigue in patients with cancer have been well characterized and there is growing understanding of the underlying biological mechanisms. Inflammation seems to have a key role in fatigue before, during, and after cancer-treatment. However, there is a considerable variability in the presentation of cancer-related fatigue, much of which is not explained by disease-related or treatment-related characteristics, suggesting that host factors might be important in the development and persistence of this symptom. Indeed, longitudinal studies have identified genetic, biological, psychosocial, and behavioural risk factors associated with cancer-related fatigue. Although no current gold-standard treatment for fatigue is available, a variety of intervention approaches have shown beneficial effects in randomized controlled trials, including physical activity, psychosocial, mind-body, and pharmacological treatments. This Review describes the mechanisms, risk factors, and possible interventions for cancer-related fatigue, focusing on recent longitudinal studies and randomized trials that have targeted fatigued patients.

    To study the relevance between cancer related fatigue and coping styles in breast cancer patients after chemotherapy. A survey was conducted in 396 patients with breast cancer after chemotherapy on cancer related fatigue scale and Jalowiec coping scale, and the relation was analyzed. The rate of overall fatigue in breast cancer patients was 96.97%, mostly moderate fatigue. The rate of fatigue dimensions from high to low was physical fatigue, feeling fatigue and cognitive fatigue, respectively. The score of coping styles in patients with breast cancer after chemotherapy from high to low was optimistic coping, facing bravely, support seeking, self-reliance, emotional catharsis, avoidance, fatalism, and conservation. The most widely used coping style was optimistic coping style, and the least was emotional catharisis. There was a positive correlation between coping style of emotional catharsis and cancer related fatigue of all dimensions (Pself-reliance, or conservation (P<0.05). There was also a negative correlation between physical fatigue and optimistic or support seeking (P<0.05), but there was a positive correlation between avoidance or fatalism and the dimensions of general fatigue, physical fatigue, and cognitive fatigue (P<0.05). There is prevalent cancer related fatigue in patients with breast cancer after chemotherapy. We should guide the patients to more active coping styles, to enhance the ability of psychological adaption in patients, reduce cancer related fatigue, and improve the quality of life.

    Full Text Available There is an estimated 3 million women in the US living as breast cancer survivors and persistent cancer related fatigue (PCRF disrupts the lives of an estimated 30% of these women. PCRF is associated with decreased quality of life, decreased sleep quality, impaired cognition and depression. The mechanisms of cancer related fatigue are not well understood; however, preliminary findings indicate dysfunctional activity in the brain as a potential factor. Here we investigate the relationship between PCRF on intrinsic resting state connectivity in this population. Twenty-three age matched breast cancer survivors (15 fatigued and 8 non-fatigued who completed all cancer-related treatments at least 12 weeks prior to the study, were recruited to undergo functional connectivity magnetic resonance imaging (fcMRI. Intrinsic resting state networks were examined with both seed based and independent component analysis methods. Comparisons of brain connectivity patterns between groups as well as correlations with self-reported fatigue symptoms were performed. Fatigued patients displayed greater left inferior parietal lobule to superior frontal gyrus connectivity as compared to non-fatigued patients (P < 0.05 FDR corrected. This enhanced connectivity was associated with increased physical fatigue (P = 0.04, r = 0.52 and poor sleep quality (P = 0.04, r = 0.52 in the fatigued group. In contrast greater connectivity in the non-fatigued group was found between the right precuneus to the periaqueductal gray as well as the left IPL to subgenual cortex (P < 0.05 FDR corrected. Mental fatigue scores were associated with greater default mode network (DMN connectivity to the superior frontal gyrus (P = 0.05 FDR corrected among fatigued subjects (r = 0.82 and less connectivity in the non-fatigued group (r = −0.88. These findings indicate that there is enhanced intrinsic DMN connectivity to the frontal gyrus in breast cancer survivors with persistent

    Fatigue affects most cancer patients and has numerous potential causes, including cancer itself and cancer treatment. Cancer-related fatigue (CRF) is not relieved by rest, can decrease quality of life, and has no FDA-approved therapy. Thyrotropin-releasing hormone (TRH) has been proposed as a potential novel treatment for CRF, but its efficacy against CRF remains largely untested. Thus, we tested the TRH analog, taltirelin (TAL), in mouse models of CRF. To model fatigue, we used a mouse model of chemotherapy, a mouse model of radiation therapy, and mice bearing colon 26 carcinoma tumors. We used the treadmill fatigue test to assess fatigue-like behavior after treatment with TAL. Additionally, we used wild-type and TRH receptor knockout mice to determine which TRH receptor was necessary for the actions of TAL. Tumor-bearing mice displayed muscle wasting and all models caused fatigue-like behavior, with mice running a shorter distance in the treadmill fatigue test than controls. TAL reversed fatigue-like behavior in all three models and the mouse TRH 1 receptor was necessary for the effects of TAL. These data suggest that TAL may be useful in alleviating fatigue in all cancer patients and provide further support for evaluating TAL as a potential therapy for CRF in humans.

    Full Text Available Question: Does supervised physical activity reduce cancer-related fatigue? Design: Systematic review with meta-analysis of randomised trials. Participants: People diagnosed with any type of cancer, without restriction to a particular stage of diagnosis or treatment. Intervention: Supervised physical activity interventions (eg, aerobic, resistance and stretching exercise, defined as any planned or structured body movement causing an increase in energy expenditure, designed to maintain or enhance health-related outcomes, and performed with systematic frequency, intensity and duration. Outcome measures: The primary outcome measure was fatigue. Secondary outcomes were physical and functional wellbeing assessed using the Functional Assessment of Cancer Therapy Fatigue Scale, European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire, Piper Fatigue Scale, Schwartz Cancer Fatigue Scale and the Multidimensional Fatigue Inventory. Methodological quality, including risk of bias of the studies, was evaluated using the PEDro Scale. Results: Eleven studies involving 1530 participants were included in the review. The assessment of quality showed a mean score of 6.5 (SD 1.1, indicating a low overall risk of bias. The pooled effect on fatigue, calculated as a standardised mean difference (SMD using a random-effects model, was –1.69 (95% CI –2.99 to –0.39. Beneficial reductions in fatigue were also found with combined aerobic and resistance training with supervision (SMD = –0.41, 95% CI –0.70 to –0.13 and with combined aerobic, resistance and stretching training with supervision (SMD = –0.67, 95% CI –1.17 to –0.17. Conclusion: Supervised physical activity interventions reduce cancer-related fatigue. These findings suggest that combined aerobic and resistance exercise regimens with or without stretching should be included as part of rehabilitation programs for people who have been diagnosed with cancer

    Full Text Available PURPOSE: A lack of fatigue-related muscle contractile property changes at time of perceived physical exhaustion and greater central than peripheral fatigue detected by twitch interpolation technique have recently been reported in cancer survivors with fatigue symptoms. Based on these observations, it was hypothesized that compared to healthy people, myoelectrical manifestation of fatigue in the performing muscles would be less significant in these individuals while sustaining a prolonged motor task to self-perceived exhaustion (SPE since their central fatigue was more prominent. The purpose of this study was to test this hypothesis by examining electromyographic (EMG signal changes during fatiguing muscle performance. METHODS: Twelve individuals who had advanced solid cancer and cancer-related fatigue (CRF, and 12 age- and gender-matched healthy controls performed a sustained elbow flexion at 30% maximal voluntary contraction till SPE. Amplitude and mean power frequency (MPF of EMG signals of the biceps brachii, brachioradialis, and triceps brachii muscles were evaluated when the individuals experienced minimal, moderate, and severe fatigue. RESULTS: CRF patients perceived physical "exhaustion" significantly sooner than the controls. The myoelectrical manifestation of muscular fatigue assessed by EMG amplitude and MPF was less significant in CRF than controls. The lower MPF even at minimal fatigue stage in CRF may indicate pathophysiologic condition of the muscle. CONCLUSIONS: CRF patients experience less myoelectrical manifestation of muscle fatigue than healthy individuals near the time of SPE. The data suggest that central nervous system fatigue plays a more important role in limiting endurance-type of motor performance in patients with CRF.

    Full Text Available Background: Fatigue is the most common side effect of cancer treatment with chemotherapy and/or radiation therapy, selected biologic response modifiers. The main purpose of this study is to evaluate the effects of aerobic exercise on cancer-related fatigue in patients of the solid tumor after chemotherapy and radiotherapy. Methods: After screening for cancer-related fatigue, 34 patients fulfilled the inclusive criteria and were assigned into two groups (n = 17 recruited in the intervention group and n = 17 in control group. The intervention group received aerobic exercise program which included treadmill walking with low to moderate intensity (50%–70% of maximum heart rate, for 20–40 min/day for 5 days/week. Control group were taught stretching exercises of hamstrings, gastrocnemius, and soleus (to be done at home and were encouraged to remain active. Outcome measures such as brief fatigue inventory (BFI, 6-min walk test, and functional assessment of cancer therapy-general (FACT-G were taken at baseline and after 6-weeks. Results: The data were analyzed using the Wilcoxon matched-pairs signed rank test for within group and Mann–Whitney U-test for between group comparisons. The results of this study showed that there was a significant reduction in cancer-related fatigue BFI score (P < 0.0001,, also there was significant improvement in the physical performance as in 6-min walk distance (P < 0.0001 and quality of life, FACT-G score (P = 0.0001. Conclusion: Aerobic exercise for 6 weeks has beneficial effects on cancer-related fatigue in patients with solid tumor after chemotherapy and/or radiotherapy.

    Cancer-related fatigue is the most prevalent and distressing symptom experienced by adolescents and young adults (AYAs). An electronic survey was undertaken to ascertain current fatigue management and perceptions of its effectiveness. Eighty-five percent of responders (68/80) experienced fatigue, and it was worse more than 1 year after cancer treatment ended, compared to fatigue management. Although advice to exercise was the most frequent intervention, the greatest impact of fatigue was on the ability to exercise and most did not find exercise advice helpful. Early intervention is warranted, supporting AYAs to persevere with increasing activity.

    Fatigue is a serious problem for the majority of patients with cancer. In this context, several studies have shown benefits of physical activity during and following treatment. However, uncertainties remain regarding the optimal type and duration of physical activity. Therefore, this study examined the relationship between cancer-related fatigue and physical activity in the course of inpatient rehabilitation. Fatigue (Multidimensional Fatigue Inventory) and physical activity (Freiburg Questionnaire of Physical Activity) were assessed in a consecutive series of 35 patients with cancer attending oncological inpatient rehabilitation during a six-month study period. The three-week rehabilitation program included daily exercise therapy consisting of aerobic endurance training, moderate resistance training, coordination exercises, relaxation training and individual physiotherapy. At discharge, a significant improvement in each dimension of cancer-related fatigue (p=0.001-0.003) and a significant increase of physical activity levels (p=0.001) were observed. A small, but significant negative correlation was found between cancer-related fatigue and the level of physical activity (R=-0.438, p=0.004). The largest effects were associated with a weekly energy expenditure of 3000 kcal through physical activity. The results support a non-linear dose-response relationship between cancer-related fatigue and physical activity. Since this is the first study providing specific exercise recommendations for an effective treatment of cancer-related fatigue in the context of inpatient rehabilitation, further research is required to validate the observed trends.

    Cancer-related fatigue (CRF) is a key concern for people living with cancer and can impair physical functioning and activities of daily living. Evidence-based guidelines for CRF are available, yet inconsistently implemented globally. This study aimed to identify barriers and enablers to applying a cancer fatigue guideline and to derive implementation strategies. A mixed-method study explored the feasibility of implementing the CRF guideline developed by the Canadian Association for Psychosocial Oncology (CAPO). Health professionals, managers and consumers from different practice settings participated in a modified Delphi study with two survey rounds. A reference group informed the design of the study including the surveys. The first round focused on guideline characteristics, compatibility with current practice and experience, and behaviour change. The second survey built upon and triangulated the first round. Forty-five health practitioners and managers, and 68 cancer survivors completed the surveys. More than 75% of participants endorsed the CAPO cancer related fatigue guidelines. Some respondents perceived a lack of resources for accessible and expert fatigue management services. Further barriers to guideline implementation included complexity, limited practical details for some elements, and lack of clinical tools such as assessment tools or patient education materials. Recommendations to enhance guideline applicability centred around four main themes: (1) balancing the level of detail in the CAPO guideline with ease of use, (2) defining roles of different professional disciplines in CRF management, (3) how best to integrate CRF management into policy and practice, (4) how best to ensure a consumer-focused approach to CRF management. Translating current knowledge on optimal management of CRF into clinical practice can be enhanced by the adoption of valid guidelines. This study indicates that it is feasible to adopt the CAPO guidelines. Clinical application may

    To investigate the prevalence of cancer-related fatigue and explore the relationship between resilience, positive affect, and fatigue among Chinese patients with gastric cancer. Cancer-related fatigue is the most distressing symptom reported frequently by cancer patients during both treatment and survival phases. Resilience and positive affect as vital protective factors against cancer-related fatigue have been examined, but the underlying psychological mechanisms are not well understood. A cross-sectional study. Two hundred and three gastric cancer patients were enrolled from three hospitals in China. The Cancer Fatigue Scale, the positive affect subscale of the Positive and Negative Affect Schedule and the Connor-Davidson Resilience Scale (CD-RISC10) were administered. Hierarchical linear regression modelling was conducted to examine the association between resilience and cancer-related fatigue, and the mediating effect of positive affect. The incidence of clinically relevant fatigue among patients with gastric cancer was 91.6%. Regression analysis showed that resilience was negatively associated with cancer-related fatigue, explaining 15.4% of variance in cancer-related fatigue. Mediation analysis showed that high resilience was associated with increased positive affect, which was associated with decreased cancer-related fatigue. Cancer-related fatigue is prevalent among patients with gastric cancer. Positive affect may mediate the relationship between resilience and cancer-related fatigue. Interventions that attend to resilience training and promotion of positive affect may be the focus for future clinical and research endeavours. © 2017 John Wiley & Sons Ltd.

    2012-09-01

    Full Text Available Background : Fatigue is the most common and distressing symptom reported by breast cancer survivors and yet the pathophysiology of cancer-related fatigue remains largely unknown. Fatigue is associated with lower parasympathetic and higher sympathetic nervous system activity in non-cancer samples, but only one study has demonstrated this same relationship in breast cancer survivors. This study evaluates the relationship between fatigue and basal autonomic nervous system activity as measured by heart rate variability (HRV in a sample of breast cancer survivors. Methods : Women who had been diagnosed with early stage breast cancer before the age of 50 were recruited from the UCLA tumor registry and completed psychological questionnaires, including measures of fatigue. A subset of these women (n=30 participated in a follow-up study in which they completed measures of fatigue, energy and mood four times per day for 5 days using electronic diaries, provided 3 days of saliva samples for cortisol assessment and underwent physiological assessment including electrocardiogram (ECG. HRV was assessed via ECG R-R wave spectral and time sequence analysis. Results : Questionnaire measures of fatigue were negatively associated with indices of parasympathetic nervous system activity, B= − 3.85, p = 0.04 for RMSSD (root of the mean squared difference of successive normal to normal waves and B= − 76.97, p = 0.04 for LF power % (low-frequency wave power percentage. Daily fatigue was also associated with lower basal HRV, B= − 15.1, p = 0.04 for RMSSD. However, fatigue indices were not associated with sympathetic nervous system activity as measured by low- to high-frequency wave ratio. Of note, fatigue was not associated with average daily cortisol output (AUC. Conclusions : Lower HRV has been associated with increased chronic inflammation, which is elevated in cancer survivors reporting persistent fatigue, thus providing insight into

    Cancer-related fatigue (CRF) is a common and one of the most severe symptom in the period of onset, diagnosis, treatment and rehabilitation process of cancer. But there are no confirmed measures to relieve this problem at present. Traditional Chinese medical comprehensive therapy has its advantages in dealing with this condition. Based on the research status of CRF, the following problems have been analyzed and solved: the term of CRF has been defined and recommended, and the definition has been made clear; the disease mechanism is proposed, i.e. healthy qi has been impaired in the long-term disease duration, in the process of surgery, chemotherapy, radiotherapy and biology disturbing; it is clear that the clinical manifestations are related to six Chinese medicine patterns: decreased functioning of the Pi (Spleen) and Wei (Stomach), deficiency of the Pi with dampness retention, deficiency of the Xin (Heart) and Pi, disharmony between the Gan (Liver) and Pi, deficiency of the Pi and Shen (Kidney), and deficiency of the Fei (Lung) and Shen. Based on its severity, the mild patients are advised to have non-drug psychological intervention and sleep treatment in cooperation with appropriate exercise; diet therapy are recommended to moderate patients together with sleep treatment and acupuncture, severe patients are recommended to have herbal treatment based on pattern differentiation together with physiological sleep therapy.

    Exercise is recommended for cancer patients to reduce fatigue and improve quality of life. This study's aim is to evaluate the influence of an exergaming protocol on cancer-related fatigue, muscle fatigue, and muscle strength in cancer patients. We conducted a quasi-experimental control study using exergaming in all groups through an Xbox360 Kinect™ console, two to three times per week, for 20 sessions. Three groups were created: cancer patients in chemotherapy and/or radiotherapy group (CRG; n:15), cancer patients after chemotherapy and/or radiotherapy (CAG; n:15), and a control group (CG; n:15). They were assessed for cancer-related fatigue using the fatigue subscale of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire. To assess dorsiflexor and plantar flexor muscle functioning, we used median frequency (MDF) of the surface electromyography and muscle strength using a dynamometer. The assessments were performed preintervention (EV0), after 10 sessions (EV1), and after 20 sessions (EV2). With an exergaming protocol, CRG and CAG showed a reduction in related fatigue compared with CG (P fatigue, including muscle fatigue, and increasing muscle strength in patients' legs.

    Sixty percent of cancer survivors are 65years of age or older. Cancer and its treatments lead to cancer-related fatigue and many other side effects, in turn, creating substantial global side-effect burden (total burden from all side effects) which, ultimately, compromises functional independence and quality of life. Various modes of exercise, such as yoga, reduce cancer-related fatigue and global side-effect burden in younger cancer survivors, but no studies have specifically examined the effects of yoga on older cancer survivors. The purpose of this study was to assess the effects of a 4-week yoga intervention (Yoga for Cancer Survivors: YOCAS©®) on overall cancer-related fatigue, and due to its multidimensional nature, the subdomains of cancer-related fatigue (general, physical, emotional, and mental) and global side-effect burden in older cancer survivors. We conducted a secondary analysis on data from a multicenter phase III randomized controlled clinical trial with 2 arms (standard care and standard care plus a 4-week YOCAS©® intervention). The sample for this secondary analysis was 97 older cancer survivors (≥60years of age), between 2months and 2years post-treatment, who participated in the original trial. Participants in the YOCAS©® intervention arm reported significantly lower cancer-related fatigue, physical fatigue, mental fatigue, and global side-effect burden than participants in the standard care arm following the 4-week intervention period (peffective standardized yoga intervention for reducing cancer-related fatigue, physical fatigue, mental fatigue, and global side-effect burden among older cancer survivors.

    Cancer-related fatigue is one of the most common symptoms experienced by cancer patients, and it diminishes their quality of life. However, there is currently no confirmed standard treatment for cancer-related fatigue, and thus, many patients who suffer cancer-related fatigue seek complementary and alternative medicines such as moxibustion. Moxibustion is one of the most popular therapies in traditional Korean medicine used to manage fatigue. Recent studies have also demonstrated that moxibustion is effective for treating chronic fatigue. However, there is insufficient evidence supporting the effect of moxibustion against cancer-related fatigue. The aim of this study is to assess the efficacy and safety of moxibustion treatment for cancer-related fatigue. A multi-center, three-armed parallel, randomized controlled trial will be conducted. Ninety-six patients with cancer-related fatigue will be recruited from three clinical research centers. They will be randomly allocated to one of three groups in a 1:1:1 ratio. The moxibustion group will receive moxibustion treatment at CV8, CV12, LI4 and ST36. The sham moxibustion group will receive sham moxibustion at non-acupoints. Both the moxibustion and sham moxibustion groups will receive 30-min treatments twice a week for 8 weeks. The usual care group will not receive moxibustion treatment. All participants will be educated via a brochure on how to manage cancer-related fatigue in daily life. The outcome measurements will be evaluated at baseline, week 5, week 9, and week 13 by assessors who are blinded to the group allocation. The primary outcome measure will be the mean change in the average scores of the Brief Fatigue Inventory before and after treatments between groups. The secondary outcome measures will be the mean difference in changes from baseline of the Brief Fatigue Inventory, functional assessments of cancer therapy-fatigue, European Organization for Research and Treatment of Cancer Quality of Life

    Fatigue is a prevalent and debilitating side effect of docetaxel chemotherapy in metastatic prostate cancer. A better understanding of the kinetics and nature of docetaxel-related fatigue may provide a framework for intervention. This secondary analysis was performed using the MOTIF database, from a phase III, randomised, double-blind, placebo-controlled study of modafinil (200 mg/day for 15 days) for docetaxel-related fatigue in men with metastatic prostate cancer [1]. The pattern of fatigue was analysed using the MDASI (MD Anderson Symptom Inventory) score. The impact of modafinil, cumulative docetaxel exposure, age and smoking status on fatigue kinetics were explored. Fatigue-related symptoms were assessed using the SOMA6 (fatigue and related symptoms) subset of the SPHERE (Somatic and Psychological Health Report). Mood was tracked using the short form 36 health survey questionnaire (SF-36). Across four docetaxel cycles, fatigue scores were higher in the first week and decreased over weeks two and three. Whilst men randomised to modafinil had reduced fatigue scores, cumulative docetaxel had little impact. Younger men (55-68 years) had significantly reduced fatigue scores, whereas current and ex-smokers had higher scores. There was no significant change in mood status or haemoglobin across treatment cycles. Men described both 'somnolence' and 'muscle fatigue' contributing significantly to their symptom complex. Assessment and management of docetaxel-related fatigue remains an important challenge. Given the complex, multifactorial nature of fatigue, identification through structured interview and interventions targeted to specific 'at risk' groups may be the most beneficial. Understanding the temporal pattern (kinetics) and nature of fatigue is critical to guide this process.

    Full Text Available To investigate whether fatigue induced by an intermittent motor task in patients with cancer-related fatigue (CRF is more central or peripheral.Ten patients with CRF who were off chemo and radiation therapies and 14 age-matched healthy controls were enrolled. Participants completed a Brief Fatigue Inventory (BFI and performed a fatigue task consisting of intermittent elbow-flexion contractions at submaximal (40% maximal voluntary contraction intensity till self-perceived exhaustion. Twitch force was elicited by an electrical stimulation applied to the biceps brachii muscle. The relative degree of peripheral (muscle vs. central contribution to fatigue induced by the intermittent motor task (IMT was assessed using twitch force ratio (TF ratio defined as post IMT twitch force to pre IMT twitch force. The total number of trials (intermittent contractions and total duration of all trials performed by each subject were also quantified.BFI scores were higher (p < 0.001 in CRF than controls, indicating greater feeling of fatigue in CRF patients than controls. A significantly smaller number of trials and shorter total duration of the trials (p < 0.05 were observed in CRF than control participants. The TF ratio (0.81 ± 0.05 in CRF was higher (p < 0.05 compared with that of controls (0.62 ± 0.05, suggesting CRF patients experienced a significantly lower degree of muscle (peripheral fatigue at the time of perceived exhaustion.Consistent with prior findings for fatigue under submaximal sustained contraction, our results indicate that motor fatigue in CRF is more of central than peripheral origin during IMT. Significant central fatigue in CRF patients limits their ability to prolong motor performance.

    Fatigue is one of the most frequent symptoms in patients with cancer. No adequate term in Spanish has been defined to describe the English concept of fatigue. To identify the most suitable Spanish words that define the concept of fatigue and to check psychometric characteristics. Consensus with professional experts on Spanish words that best suit the English concept of fatigue. A prospective study on oncologic patients was also undertaken, which included an evaluation of the intensity of fatigue through visual numeric scales (VNS) where the words had been previously selected. The fatigue subscale of the Functional Assessment of Cancer Therapy-Fatigue (FACT-F) questionnaire was taken as a reference. The experts highlighted the words cansancio, agotamiento, and debilidad (tiredness, exhaustion, and weakness) as the terms that best defined the concept of fatigue. In the psychometric assessment study, 100 patients were included, of which 61 (61%) presented diagnostic values for cancer-related fatigue in the FACT-F fatigue subscale (score 34/52 or lower). The VNS for the chosen terms obtained a high correlation with the FACT-F fatigue subscale results: cansancio (tiredness) r = -0.71, agotamiento (exhaustion) r = -0.74, debilidad (weakness) r = -0.74, with no statistical differences between them. For the detection of fatigue by means of the VNS, tiredness (cutoff point > or =4/10) gave sensitivity (S) 0.90 and specificity (E) 0.72; exhaustion (cutoff point > or =3/10) S 0.95 and E 0.90 and weakness (cutoff point > or =4/10) S 0.92 and E 0.72. The ROC curve was 0.88 for tiredness, 0.94 for exhaustion, and 0.92 for weakness, with no significant difference between the areas mentioned. The terms cansancio, agotamiento, and debilidad (tiredness, exhaustion, and weakness) are suitable for defining the English concept of fatigue in Spanish, and should be the preferred option for inclusion in evaluation tools.

    Fatigue is a common symptom in cancer patients that can persist beyond the curative treatment phase. Some evidence has been reported for interventions for fatigue during active treatment. However, to date, there is no systematic review on psychological interventions for fatigue after the completion of curative treatment for cancer. This is a protocol for a systematic review that aims to evaluate the effectiveness of psychological interventions for cancer-related fatigue in post-treatment cancer survivors. This systematic review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) database. We will search the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library), PubMed, MEDLINE, EMBASE, CINAHL, PsycINFO, and relevant sources of grey literature. Randomised controlled trials (RCTs) which have evaluated psychological interventions in adult cancer patients after the completion of treatment, with fatigue as an outcome measure, will be included. Two review authors will independently extract data from the selected studies and assess the methodological quality using the Cochrane Collaboration Risk of Bias Tool. Most existing evidence on cancer-related fatigue is from those in active cancer treatment. This systematic review and meta-analysis will build upon previous evaluations of psychological interventions in people during and after cancer treatment. With the growing need for stage-specific research in cancer, this review seeks to highlight a gap in current practice and to strengthen the evidence base of randomised controlled trials in the area.

    To assess the effectiveness and safety of Chinese herbal medicine for the treatment of cancer-related fatigue. We systematically searched seven electronic databases and two trial registries for randomized clinical trials of Chinese herbal medicine for cancer-related fatigue. Two authors independently extracted data and assessed the methodological quality of the included trials using the Cochrane risk of bias tool. Data were synthesized using RevMan 5.2 software. A total of 10 trials involving 751 participants with cancer-related fatigue were identified and the methodological quality of the included trials was generally poor. Chinese herbal medicine used alone or in combination with chemotherapy or supportive care showed significant relief in cancer-related fatigue compared to placebo, chemotherapy or supportive care based on single trials. Chinese herbal medicine plus chemotherapy or supportive care was superior to chemotherapy or supportive care in improving quality of life. Data from one trial demonstrated Chinese herbal medicine exerted a greater beneficial effect on relieving anxiety but no difference in alleviating depression. Seven trials reported adverse events and no severe adverse effects were found in Chinese herbal medicine groups. The findings from limited number of trials suggest that Chinese herbal medicine seems to be effective and safe in the treatment of cancer-related fatigue. However, the current evidence is insufficient to draw a confirmative conclusion due to the poor methodological quality of included trials. Thus, conducting rigorously designed trials on potential Chinese herbal medicine is warranted. Copyright © 2014 Elsevier Ltd. All rights reserved.

    To examine the relationship between cancer-related fatigue (CRF) and physical activity in daily living in premenopausal disease-free cervical and endometrial cancer survivors. A physical activity monitor was used to collect objective data on daily physical activity. CRF and related variables were measured using self-report scales in a cross-sectional manner. The average age was 44.9 years among 64 women. The higher CRF group comprised 22 women (34%), 10% of whom had severe fatigue. The participants had higher physical activity levels compared with the findings in previous studies, and reported an average of 40 min/day of moderate to vigorous activity. Moderate to vigorous levels of physical activity were derived from essential social activities rather than leisure time exercise. There were no significant differences in physical activity levels between the lower and higher CRF groups. Our study results suggested that the higher level of physical activity in daily living itself had no relationship with decreasing CRF among premenopausal cervical and endometrial cancer survivors. It would be better to focus on cognitive and psychological factors before introducing physical activity programs and be careful of the characteristics of the participants' physical activity among this population in daily basis.

    Cancer-related fatigue (CRF) occurs in most people with cancer undergoing chemotherapy. Physical activity (PA) is safe and effective in reducing CRF in people with cancer. 
. This project involved the implementation and evaluation of a three-month PA program to maintain or improve CRF and quality of life.
. Activity trackers and resistance bands were provided to participants. Verbal instruction, printed material, activity videos, and text messages were used in this program. Participants completed a fatigue assessment; self-reported PA measure; and measure of attitudes, beliefs, and knowledge about sustaining regular PA pre- and postimplementation.
. 51 patients enrolled in the study, and 39 completed the program. Participants' fatigue did not worsen significantly during the three months, and self-reported activity levels increased, but not significantly. The activity tracker, text messages, and personal connection with nursing staff were reported to be helpful.

    Fatigue is a crucial determinant of quality of life across rheumatic diseases, but the lack of agreed-upon standards for identifying clinically significant fatigue hinders research and clinical management. Case definition criteria for cancer-related fatigue were proposed for inclusion in the International Classification of Diseases. The objective was to evaluate whether the cancer-related fatigue case definition performed equivalently in women with breast cancer and systemic sclerosis (SSc) and could be used to identify patients with chronic illness-related fatigue. The cancer-related fatigue interview (case definition criteria met if ≥ 5 of 9 fatigue-related symptoms present with functional impairment) was completed by 291 women with SSc and 278 women successfully treated for breast cancer. Differential item functioning was assessed with the multiple indicator multiple cause model. Items 3 (concentration) and 10 (short-term memory) were endorsed significantly less often by women with SSc compared with cancer, controlling for responses on other items. Omitting these 2 items from the case definition and requiring 4 out of the 7 remaining symptoms resulted in a similar overall prevalence of cancer-related fatigue in the cancer sample compared with the original criteria (37.4% vs 37.8%, respectively), with 97.5% of patients diagnosed identically with both definitions. Prevalence of chronic illness-related fatigue was 36.1% in SSc using 4 of 7 symptoms. The cancer-related fatigue criteria can be used equivalently to identify patients with chronic illness-related fatigue when 2 cognitive fatigue symptoms are omitted. Harmonized definitions and measurement of clinically significant fatigue will advance research and clinical management of fatigue in rheumatic diseases and other conditions.

    Fatigue is a common symptom that lowers the quality of life of patients with cancer, affecting between 60% and 90% of patients. Relatively few options are available for the treatment of this debilitating condition. Modafinal, a psychostimulant developed for the treatment of narcolepsy, has been used to treat fatigue in other diseases such as multiple sclerosis, but little data support its use in cancer patients. The primary objective of this open-label pilot study was to evaluate the safety, and efficacy of modafinil in improving cancer-related fatigue (CRF) as measured by the Brief Fatigue Inventory (BFI). The effect of this agent on depression, quality of life, functional status, and cognitive function was also assessed. Modafinal was self-administered at a dose of 100 mg/d during weeks 1-2, and 200 mg during weeks 3-4. Assessments were performed at baseline, 2, and 4 weeks. BFI score was improved in 46% of patients at 2 weeks and 75% at 4 weeks (p = 0.025). Hospital Anxiety and Depression Scale scores declined at 2 and 4 weeks (p < 0.001). Most scales for neurocognitive function were unchanged. Score for all Functional Assessment of Cancer Therapy-Brain (FACT-BR) subscales (measuring quality of life), except social/family well-being, were improved (p < 0.05) at 2 and 4 weeks. Significant changes in Eastern Cooperative Oncology Group (ECOG) performance status were noted, with 40% of patients improving at least one level. Modafinil was well-tolerated with only one patient discontinuing treatment due to drug-related toxicity. In this pilot study modafinil was well-tolerated and effective for fatigue in patients with cancer. Improvements were also seen in mood, quality of life, and functional status.

    PURPOSEProlonged and disabling fatigue is prevalent after cancer treatment, but the early natural history of cancer-related fatigue (CRF) has not been systematically examined to document consistent presence of symptoms. Hence, relationships to cancer, surgery, and adjuvant therapy are unclear. PATIENTS AND METHODSA prospective cohort study of women receiving adjuvant treatment for early-stage breast cancer was conducted. Women (n = 218) were enrolled after surgery and observed at end treatment and at 1, 3, 6, 9, and 12 months as well as 5 years. Structured interviews and self-report questionnaires were used to record physical and psychologic health as well as disability and health care utilization. Patients with CRF persisting for 6 months were assessed to exclude alternative medical and psychiatric causes of fatigue. Predictors of persistent fatigue, mood disturbance, and health care utilization were sought by logistic regression.ResultsThe case rate for CRF was 24% (n = 51) postsurgery and 31% (n = 69) at end of treatment; it became persistent in 11% (n = 24) at 6 months and 6% (n = 12) at 12 months. At each time point, approximately one third of the patients had comorbid mood disturbance. Persistent CRF was predicted by tumor size but not demographic, psychologic, surgical, or hematologic parameters. CRF was associated with significant disability and health care utilization. CONCLUSIONCRF is common but generally runs a self-limiting course. Much of the previously reported high rates of persistent CRF may be attributable to factors unrelated to the cancer or its treatment.

    Full Text Available Cancer related fatigue (CRF is one of the most common side effects of cancer and its treatments. A large proportion of cancer patients experience cancer-related physical and central fatigue so new strategies are needed for treatment and improved survival of these patients. BST204 was prepared by incubating crude ginseng extract with ginsenoside-β-glucosidase. The purpose of the present study was to examine the effects of BST204, mixture of ginsenosides on 5-fluorouracil (5-FU-induced CRF, the glycogen synthesis, and biochemical parameters in mice. The mice were randomly divided into the following groups: the naïve normal (normal, the HT-29 cell inoculated (xenograft, xenograft and 5-FU treated (control, xenograft + 5-FU + BST204-treated (100 and 200 mg/kg (BST204, and xenograft + 5-FU + modafinil (13 mg/kg treated group (modafinil. Running wheel activity and forced swimming test were used for evaluation of CRF. Muscle glycogen, serum inflammatory cytokines, aspartic aminotransferase (AST, alanine aminotransferase (ALT, creatinine (CRE, white blood cell (WBC, neutrophil (NEUT, red blood cell (RBC, and hemoglobin (HGB were measured. Treatment with BST204 significantly increased the running wheel activity and forced swimming time compared to the control group. Consistent with the behavioral data, BST204 markedly increased muscle glycogen activity and concentrations of WBC, NEUT, RBC, and HGB. Also, tumor necrosis factor-α (TNF-α and interleukin-6 (IL-6, AST, ALT, and CRE levels in the serum were significantly reduced in the BST204-treated group compared to the control group. This result suggests that BST204 may improve chemotherapy-related fatigue and adverse toxic side effects.

    Although the underlying mechanisms of cancer-related fatigue (CRF) are not fully characterized, treatment-associated oxidative stress may play a role. The purpose of this study was to determine the effect of an exercise intervention on the relationship between CRF and oxidative stress. Upon cessation of radiation or chemotherapy, 8 cancer patients participated in a 10-week exercise intervention (EX), while 7 continued standard care (CON). Blood draws and fatigue questionnaires were administered to cancer patients before and after the intervention as well as to 7 age-matched individuals with no cancer history. Changes in plasma 8-hydroxy-deoxyguanosine (8-OHdG), protein carbonyls, antioxidant capacity, and fatigue were compared between groups. Correlations between CRF and oxidative stress were evaluated. Mean total fatigue scores decreased significantly (5.0 ± 2.2 to 2.6 ± 1.5, P fatigue ( r = -.58). Changes in total ( r = .46) and affective ( r = .47) fatigue exhibited significant correlations with changes in 8-OHdG over time, while behavioral ( r = .46) and sensory ( r = .47) fatigue changes were significantly correlated with protein carbonyls. Oxidative stress may be implicated in CRF, while improved antioxidant capacity following an exercise intervention may play a role in mitigating CRF in cancer survivors.

    Cancer-related fatigue greatly influences quality of life in cancer patients; however, no specific treatments have been established for cancer-related fatigue, and at present, no medication has been approved in Japan. Systematic research using patient-reported outcome to examine symptoms, particularly fatigue, has not been conducted in palliative care settings in Japan. The objective was to evaluate fatigue, pain, and quality of life in cancer patients at the point of intervention by palliative care teams. Patients who were referred to palliative care teams at three institutions and met the inclusion criteria were invited to complete the Brief Fatigue Inventory, Brief Pain Inventory, and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 15-Palliative. Of 183 patients recruited, the majority (85.8%) were diagnosed with recurrence or metastasis. The largest group (42.6%) comprised lung cancer patients, of whom 67.2% had an Eastern Cooperative Oncology Group Performance Status of 0-1. The mean value for global health status/quality of life was 41.4, and the highest mean European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 15-Palliative symptom item score was for pain (51.0). The mean global fatigue score was 4.1, and 9.8%, 30.6%, 38.7%, and 20.8% of patients' fatigue severity was classified as none (score 0), mild (1-3), moderate (4-6), and severe (7-10), respectively. Cancer-related fatigue, considered to occur more frequently in cancer patients, was successfully assessed using patient-reported outcomes with the Brief Fatigue Inventory for the first time in Japan. Results suggested that fatigue is potentially as problematic as pain, which is the main reason for palliative care.

    Patients' lived experience of illness and health is receiving increased attention in the medical field. Understanding patients' perspective and experiences is an undoubted asset for efficient health interventions and improved clinical concordance. Patients' experiences of care and cure, however, are influenced by the cultural setting in which these experiences take place. This implies that health interventions should be "ecological" and attuned to the specific sociocultural context of the patients. Our research group is conducting a cross-cultural qualitative study aimed ad exploring how fatigue (a symptom very common in cancer) is perceived and manifested by patients in different countries (Canada, Thailand, England and Italy). In order to achieve this, the study was design according to the method of Ethnoscience, that appeared to us the best suited to explore the meanings that patients attribute to their state and the linguistic patterns they use to describe it. In this paper we will describe in details the process of Ethnoscience and will discuss the heuristic value of this research approach. Ethnoscience was an effective research strategy for exploring how beliefs and values shape symptoms and the behavioural manifestations of cancer related fatigue. This paper discusses the heuristic value of Ethnoscience and its applicability to the study of health relate topics, particularly those where issues of social construction are important. Ethnoscience is a promising and innovative research approach, able to cast light on the way people experience and make sense of their illness. Copyright © 2011 Elsevier Ireland Ltd.

    Symptoms of depression and cancer-related fatigue (CRF) are common among breast cancer patients postchemotherapy and may seriously impair quality of life (QoL). This study aimed to assess the relationship between depression and CRF in breast cancer patients postchemotherapy and to examine their relationships to optimism and to threat and challenge appraisals. Participants included 95 breast cancer patients (stages 1-3) 1 to 6 months after completion of chemotherapy. Patients submitted personal and medical details and completed the following: physical symptom questionnaires (EORTC QLQ-C30, and QLQ-BR23), a symptoms of depression questionnaire (CES-D), the Fatigue Symptom Inventory (FSI), the Life Orientation Test (LOT-R), and a stress appraisals questionnaire. We found levels of depression, CRF, and appraisals of cancer as a threat to bemoderate and levels of optimism and appraisals of cancer as a challenge to be high. Depression and CRF were positively associated. A multivariate regression analysis revealed that 51% of the CRF variancewas explained; physical symptoms and threat appraisal were significantly associated with CRF. A 67% of the CRF variance of depression was explained; challenge and threat appraisals were significantly associated with depression [corrected]. Although CRF and depression were often experienced simultaneously and both were found to be higher among individuals who gave higher appraisals of cancer as a threat, only depression was related to optimism and challenge appraisals, while CRF was related mainly to intensity of physical symptoms. The different pattern of associations between optimism and appraisals warrants further clinical attention as well as future study.

    Full Text Available Starting with patient’ diagnose and continuing throughout the treatment and thereafter, cancer-related fatigue (CRF is a distressing and disabling symptom, highly prevalent across the cancer continuum2. This is a review article mainly focusing on the rehabilitation objectives and interventions in CRF, and implementation issues, according to the report of an NCCN member institution4. Implementation is the most problematic, considering the large number of patients to whom it is addressed to and the variety of pathologies within this group of patients. The onset of CRF is difficult to establish, because of the limitations of reporting this symptom4, but it is a valuable predictor in prognosis. The main interventions in rehabilitation applicable to these patients are discussed in correlation to the objectives of each phase of therapeutic management in cancer: pre-operatory, before, during or after radio and/or chemotherapy Conclusion: Rehabilitation interventions should be applied to all patients diagnosed with cancer, according to their phase of oncologic treatment and the objectives. This should be practiced as preventive measure, but as a therapeutic one to, considering the high incidence of CFR before diagnose.

    We prospectively designed a Taiwan cancer-related fatigue cognition questionnaire, version 1.0 (TCRFCQ-V1.0), for Taiwanese patients with cancer and investigated the reliability and validity of this questionnaire. The completion rate of the TCRFCQ-V1.0 was high (97% of the patients completed all items), and the rate of missing data was low (0.2%-1.1% for each item). Moreover, the Cronbach alpha value was 0.889. We eliminated 5 items because their respective Cronbach alpha values were higher than the total mean value of Cronbach's alpha. Overall, the TCRFCQ-V1.0 had adequate Cronbach alpha coefficients (range, from 0.882 to 0.889). In addition, the results of Bartlett's test were significant (chi-squared, 2390.11; p Kaiser-Meyer-Olkin statistic of 0.868. Through exploratory factor analysis, we identified 6 factors with eigenvalues of > 1, and the scree plot indicated no flattening factors. Overall, 28 items achieved a factor loading of ≥ 0.55. We enrolled patients with cancer who were aged > 18 years, had received a pathological diagnosis of cancer, and had undergone cancer treatments such as surgery, chemotherapy, radiotherapy, or concurrent chemoradiotherapy at a single institute in Taiwan. Of the identified 167 eligible patients, 161 (96.4%) were approached. Of these patients, 6 (7.2%) declined to participate and 155 (92.8%) were interviewed. The initial 43 items in the TCRFCQ-V1.0 were assessed for ceiling and floor effects. The TCRFCQ-V1.0 is a reliable and valid instrument for measuring CRF cognition in Taiwanese patients with cancer.

    Cancer-related fatigue (CrF) is the most common and disruptive symptom experienced by cancer survivors. We aimed to develop a theory-based, interactive Web-based intervention designed to facilitate self-management and enhance coping with CrF following cancer treatment. The aim of our study was to outline the rationale, decision-making processes, methods, and findings which led to the development of a Web-based intervention to be tested in a feasibility trial. This paper outlines the process and method of development of the intervention. An extensive review of the literature and qualitative research was conducted to establish a therapeutic approach for this intervention, based on theory. The psychological principles used in the development process are outlined, and we also clarify hypothesized causal mechanisms. We describe decision-making processes involved in the development of the content of the intervention, input from the target patient group and stakeholders, the design of the website features, and the initial user testing of the website. The cocreation of the intervention with the experts and service users allowed the design team to ensure that an acceptable intervention was developed. This evidence-based Web-based program is the first intervention of its kind based on self-regulation model theory, with the primary aim of targeting the representations of fatigue and enhancing self-management of CrF, specifically. This research sought to integrate psychological theory, existing evidence of effective interventions, empirically derived principles of Web design, and the views of potential users into the systematic planning and design of the intervention of an easy-to-use website for cancer survivors. ©Teresa Corbett, Jane C Walsh, AnnMarie Groarke, Rona Moss-Morris, Eimear Morrissey, Brian E McGuire.

    Cancer-related fatigue (CRF) remains one of the most prevalent and troublesome adverse events experienced by patients with cancer during and after therapy. To perform a meta-analysis to establish and compare the mean weighted effect sizes (WESs) of the 4 most commonly recommended treatments for CRF-exercise, psychological, combined exercise and psychological, and pharmaceutical-and to identify independent variables associated with treatment effectiveness. PubMed, PsycINFO, CINAHL, EMBASE, and the Cochrane Library were searched from the inception of each database to May 31, 2016. Randomized clinical trials in adults with cancer were selected. Inclusion criteria consisted of CRF severity as an outcome and testing of exercise, psychological, exercise plus psychological, or pharmaceutical interventions. Studies were independently reviewed by 12 raters in 3 groups using a systematic and blinded process for reconciling disagreement. Effect sizes (Cohen d) were calculated and inversely weighted by SE. Severity of CRF was the primary outcome. Study quality was assessed using a modified 12-item version of the Physiotherapy Evidence-Based Database scale (range, 0-12, with 12 indicating best quality). From 17 033 references, 113 unique studies articles (11 525 unique participants; 78% female; mean age, 54 [range, 35-72] years) published from January 1, 1999, through May 31, 2016, had sufficient data. Studies were of good quality (mean Physiotherapy Evidence-Based Database scale score, 8.2; range, 5-12) with no evidence of publication bias. Exercise (WES, 0.30; 95% CI, 0.25-0.36; P psychological (WES, 0.27; 95% CI, 0.21-0.33; P psychological interventions (WES, 0.26; 95% CI, 0.13-0.38; P psychological mode, type of control condition, use of intention-to-treat analysis, and fatigue measures (WES range, -0.91 to 0.99).

    Full Text Available Cancer related fatigue (CRF is the most disabling and distressing symptom in cancer, throughout the whole history of the illness, including successfully treated cases. Rehabilitation medicine could have a positive impact on these patients’ outcomes, if well targeted. With these purpose, the rehabilitation clinician needs to correctly assess fatigue using standard, reliable scales. This review of articles and trials synthesizes the epidemiology, mechanics (including causes and effects, clinical presentation and means of assessment in CRF. CRF causes and mechanisms are not well known. Understanding them would provide specific targets to fatigue management. Clinical presentation is very variable, a wide range of features being found in literature. Poorly medical reports in assessing fatigue offer variable percentages of prevalence, inconsistent with patients’ daily burden due to CRF. There are many tools used to assess fatigue in clinical research and on them depends the percentages reported as fatigue prevalence. The hereby gathered information are useful in the approach of a patient that addresses to a rehabilitation clinician for CRF management.

    Cancer patients frequently suffer from fatigue, a complex syndrome associated with tiredness and depressed mood. Cancer-related fatigue (CRF) can be present at the time of diagnosis, escalates during treatment, and can persist for years after treatment. CRF negatively influences quality of life, limits functional independence, and is associated with decreased survival in patients with incurable disease. We have previously shown that increased pro-inflammatory cytokine expression in the brain contributes to depressive- and fatigue-like behaviors in a mouse model of CRF. Inflammatory cytokines increase the activity of indoleamine 2,3-dioxygenase (IDO) and kynurenine 3-monooxygenase (KMO), which competitively reduce serotonin synthesis. Reduced serotonin availability in the brain and increased production of alternative neuroactive metabolites of tryptophan are thought to contribute to the development of depression and fatigue. The purpose of this study was to determine the effects of fluoxetine, a selective serotonin reuptake inhibitor (SSRI), on brain cytokines and behavioral measures of fatigue and depression in tumor-bearing mice. Here we show that tumor growth increased brain expression of pro-inflammatory cytokines and KMO. Treatment with fluoxetine had no effect on tumor growth, muscle wasting, fatigue behavior, or cytokine expression in the brain. Fluoxetine, however, reduced depressive-like behaviors in tumor bearing mice. In conclusion, our data confirm that increased brain expression of pro-inflammatory cytokines is associated with tumor-induced fatigue- and depressive-like behaviors. However, it is possible to separate the effects of tumor growth on mood and fatigue-like behaviors using SSRIs such as fluoxetine. Copyright © 2014 Elsevier Inc. All rights reserved.

    Thyroid dysfunction has been reported during Regorafenib (Reg) administration, but no detailed study is presently available. Prospective, observational cohort study. Patients with documented metastatic colorectal cancer and progression of disease during or within 3 months after the last standard therapy, with no evidence and history of previous thyroid disease were enrolled. Twenty-five consecutive patients were evaluated before and 8-50 weeks after initiating Reg therapy by monthly clinical, ultrasound and laboratory (thyrotropin (TSH), free thyroxine (fT4), antithyroglobulin (TgAb) and antithyroid peroxidase (TPOAb)) evaluation. Thirteen/25 patients (52%) became hypothyroid (TSH: 12.5 ± 4.01 IU/L, range: 4.6-22.0) within 5 months of therapy. TPOAb became detectable (99-155 IU/mL) in 2/25 (8%) patients. Thyroid volume progressively decreased (from 8.6  ±  2.2 mL to 4.9 ± 2.4 mL after 5 months of Reg therapy, P  hypothyroidism (43 weeks) than in those remaining euthyroid (17 weeks, P  hypothyroidism severity and reversed after levothyroxine therapy (L-T4). Reg rapidly causes hypothyroidism in about 50% of patients and in a minority of them also triggers thyroid autoimmunity. Reg-induced hypothyroidism was strictly related to fatigue, easily reversed by L-T4 administration and associated to longer survival. These results suggest that prompt recognition of hypothyroidism in patients with severe fatigue may prevent unnecessary Reg dose reduction or withdrawal. © 2017 European Society of Endocrinology.

    Radiotherapy is known to cause debilitating treatment related fatigue. Fatigue in general is a conglomeration of psychological, physical, hematological and unknown factors influencing the internal milieu of the cancer patient. Radiotherapy can add stress at the cellular and somatic level to aggravate further fatigue in cancer patients undergoing radiotherapy. Stress related hormones might be mediating in the development of fatigue. This is an ongoing prospective study to evaluate if the hormonal profile related to stress is influenced by radiotherapy treatment related fatigue. The study was conducted from September 2002 onwards in the division of Radiotherapy and Oncology of our Medical School. Previously untreated patients with histopathology proof of malignancy requiring external beam radiotherapy were considered for this study. Selection criteria were applied to exclude other causes of fatigue. Initial fatigue score was obtained using Pipers Fatigue Score questionnaire containing 23 questions, subsequently final fatigue score was obtained at the end of radiotherapy. Blood samples were obtained to estimate the levels of ACTH, TSH, HGH, and cortisol on the final assessment. The hormone levels were compared with resultant post radiotherapy fatigue score. At the time of reporting 50 patients were evaluable for the study. The total significant fatigue score was observed among 12 (24%) patients. The individual debilitating fatigue score were behavioral severity 14 (28%), affective meaning 14(28%), Sensory 13 (26%) and cognitive mood 10 (20%) respectively. From the analysis of hormonal profile, growth hormone level > 1 ng/mL and TSH <0.03 appears to be associated with high fatigue score (though statistically not significant); whereas there was no correlation with ACTH and serum cortisol level. In our prospective study severe radiotherapy treatment related fatigue was found among our patient population. Low levels of TSH and high levels of GH appear to be associated

    Purpose Cancer-Related Fatigue (CRF) negatively affects quality of life among cancer patients. This study seeks to evaluate the outcome and patient receptiveness of a brief counseling program based on National Cancer Institute (NCI) PDQ® information to manage CRF when integrated into Radiation Therapy (RT). Methods We conducted a prospective cohort study among patients undergoing non-palliative RT. Patients with stage I–III tumors and with Karnofsky score 60 or better were given a ten-minute behavioral counseling session during the first two weeks of RT. The Brief Fatigue Inventory (BFI) was administered at baseline/end of RT. Results Of 93 patients enrolled, 89% found the counseling useful and practical. By the end of RT, 59% reported increased exercise, 41.6% sought nutrition counseling, 72.7% prioritized daily activities, 74.4% took daytime naps, and 70.5% talked with other cancer patients. Regarding counseling, patients who had received chemotherapy prior to RT had no change in fatigue (−0.2), those who received RT alone had mild increase in fatigue (0.7, p=0.02), and those who received concurrent chemotherapy experienced a substantial increase in fatigue (3.0 to 5.2, p=0.05). Higher baseline fatigue and receipt of chemotherapy were predictive of worsened fatigue in a multivariate model (both p<0.01). Conclusion Our data suggests that brief behavioral counseling based on NCI guidelines is well accepted by patients showing an uptake in many activities to cope with CRF. Those who receive concurrent chemotherapy and with higher baseline fatigue are at risk for worsening fatigue despite of guideline-based therapy. PMID:29479490

    The aim of this study is to examine factors contributing to cancer-related fatigue (CRF) in breast cancer patients who have undergone surgery. Sixty women (mean age: 50.0) completed self-rated questionnaires assessing components of CRF, muscular and cognitive functions. Also, physiological and subjective data were gathered. Data were analyzed using partial least squares variance-based structural equation modeling in order to examine factors contributing to CRF after breast surgery. The tested model was robust in terms of its measurement quality (reliability and validity). According to the structural model results, emotional distress (β = 0.59; p accounting for 61% of the explained variance. Also, emotional distress (β = 0.41; p accounted for 41% of the explained variance. However, the relationship between low physical function and CRF was weak and nonsignificant (β = 0.01; p > 0.05). Emotional distress, altered vigilance capacity, and pain are associated with CRF in postsurgical breast cancer. In addition, emotional distress and pain are related to diminished physical function, which, in turn, has no significant impact on CRF. The current model should be examined in subsequent phases of the treatment (chemotherapy and/or radiotherapy) when side effects are more pronounced and may lead to increased intensity of CRF and low physical function.

    Full Text Available Abstract Background Fatigue is prevalent in breast cancer survivors and has profound effects on daily life. The interference of fatigue with endocrine therapy may be difficult to separate. This study investigates the prevalence and severity of fatigue and identifies the demographic, clinical, and lifestyle factors associated with cancer-related fatigue (CRF in breast cancer patients undergoing endocrine therapy in an urban area. Methods Women with stage I-IIIA breast cancer were recruited and asked to participate (n = 371 in the study. The 315 women who responded to the questionnaire (84.9%, 54 (17.1% had completed endocrine therapy and 261 (82.9% were still undergoing endocrine therapy. The patients had been diagnosed at an average of 31 months prior to recruitment (range, 7 to 60 months; the average age was 48 (range, 33 to 72 years. The 11-point scale and Visual Analog Scale (VAS were employed to quantify the level of fatigue experienced by the patients. Logistic regression analyses and a trend test method were performed to evaluate factors associated with CRF. Results Among the 315 patients, 189 (60% had experienced or were experiencing CRF during endocrine therapy. Logistic regression analysis was performed to identify factors associated with CRF, including BMI (body mass index, clinical stage, menopausal status, duration of endocrine therapy, physical activity, and diet. Factors unrelated to CRF were age, marital status, treatment, endocrine therapy drugs, alcohol intake, and smoking. The trend test method revealed an association between physical activity and dietary level and the intensity of CRF. Conclusions The present findings suggest that fatigue is an important problem in the majority of breast cancer patients during endocrine therapy. We found that BMI, clinical stage, menopausal status, duration of endocrine therapy, physical activity, and diet are associated with fatigue. Future research should focus on the impact factors of CRF

    Although cancer-related fatigue (CRF) has gained increased attention in the past decade, it remains difficult to treat. An integrative approach combining conventional and complementary medicine interventions seems highly promising. Treatment programs are more likely to be effective if the needs and interests of the people involved are well represented. This can be achieved through stakeholder engagement. The aim of the study was to develop an integrative CRF treatment program using stakeholder engagement and to compare it to an expert version. In a qualitative study, a total of 22 stakeholders (4 oncologists, 1 radiation-oncologist, 1 psycho-oncologist, 5 nurses/nurse experts, 9 patients, 1 patient family member, 1 representative of a local Swiss Cancer League) were interviewed either face-to-face or in a focus group setting. For data analysis, qualitative content analysis was used. With stakeholder engagement, the integrative CRF treatment program was adapted to usual care using a prioritizing approach and allowing more patient choice. Unlike the expert version, in which all intervention options were on the same level, the stakeholder engagement process resulted in a program with 3 different levels. The first level includes mandatory nonpharmacological interventions, the second includes nonpharmacological choice-based interventions, and the third includes pharmacological interventions for severe CRF. The resulting stakeholder based integrative CRF treatment program was implemented as clinical practice guideline at our clinic (Institute for Complementary and Integrative Medicine, University Hospital Zurich). Through the stakeholder engagement approach, we integrated the needs and preferences of people who are directly affected by CRF. This resulted in an integrative CRF treatment program with graded recommendations for interventions and therefore potentially greater sustainability in a usual care setting.

    Full Text Available Abstract Background Cancer-related fatigue (CRF and its impact on patients' quality of life has been an increasing subject of research. However, in Germany there is a lack of evidence-based interventions consistent with the multidimensional character of fatigue. The objective of this study is to develop and evaluate a self-management program for disease-free cancer patients to cope with CRF. Methods Based on evidence extracted from a literature review, a curriculum for the self-management program was elaborated. The curriculum was reviewed and validated by an interdisciplinary expert group and the training-modules will be pretested with a small number of participants and discussed in terms of feasibility and acceptance. To determine the efficacy of the program a randomised controlled trial will be carried out: 300 patients will be recruited from oncological practices in Bremen, Germany, and will be allocated to intervention or control group. The intervention group participates in the program, whereas the control group receives standard care and the opportunity to take part in the program after the end of the follow-up (waiting control group. Primary outcome measure is the level of fatigue, secondary outcome measures are quality of life, depression, anxiety, self-efficacy and physical activity. Data will be collected before randomisation, after intervention, and after a follow-up of 6 months. Discussion Because there are no comparable self-management programs for cancer survivors with fatigue, the development of the curriculum has been complex; therefore, the critical appraisal by the experts was an important step to validate the program and their contributions have been integrated into the curriculum. The experts appreciated the program as filling a gap in outpatient cancer care. If the results of the evaluation prove to be satisfactory, the outpatient care of cancer patients can be broadened and supplemented. Trial Registration Clinical

  20. The effect of intravenous vitamin C on cancer- and chemotherapy-related fatigue and quality of life

    Full Text Available Cancer patients commonly experience a number of symptoms of disease progression and the side effects of radiation therapy and adjuvant chemotherapy, which adversely impact on their quality of life. Fatigue is one of the most common and debilitating symptoms reported by cancer patients and can affect quality of life more than pain. Several recent studies have indicated that intravenous vitamin C alleviates a number of cancer- and chemotherapy-related symptoms, such as fatigue, insomnia, loss of appetite, nausea and pain. Improvements in physical, role, cognitive, emotional and social functioning, as well as an improvement in overall health, were also observed. In this mini review we briefly cover the methods commonly used to assess health-related quality of life in cancer patients, and describe the few recent studies examining the effects of intravenous vitamin C on cancer- and chemotherapy-related quality of life. We discuss potential mechanisms that might explain an improvement in quality of life and also considerations for future studies.

    To identify the links between self-esteem, fatigue and health-related quality of life for children and young people during and following treatment for cancer. Measures to minimise adverse outcomes for survivors of childhood cancer have been developed, but the crucial periods of returning to school and transition to adult life and adult services are not addressed so well. Screening of quality of life, fatigue and self-esteem in childhood cancer patients during and after treatment is important for optimising the nursing response and improving outcomes for children. A cross-sectional, descriptive, correlational, comparative survey was designed. Validated measures of the attributes being studied were used. This study was conducted in private rooms on the ward and in the outpatient clinic of a major oncology hospital in Jordan in 2015. Seventy children aged 5-16 years were included. Ethical approval was secured. The age range of the children was 5-16 years (Mean 10·17, SD 3·4 years). Thirty were girls and 40 were boys. The total quality of life scores ranged from 21-100 (M = 65·5; SD = 17·6). The total scores of fatigue range from 12·5-100 (M = 65·79; SD = 22·20). Children with a high level of fatigue experienced lower quality of life. Continuing education centres at hospitals may find the results of this study helpful to provide professional updates and training events to enhance nurses' understanding of psychosocial distress responses and ability to intervene effectively within the multiprofessional effort. The outcomes of this study may enhance the development of guidelines for routine assessment by nurses and others of these factors among children with cancer. The nursing role in ensuring holistic care and attention to the problems of most concern to patients could be strengthened. © 2016 John Wiley & Sons Ltd.

    Persistent fatigue and depressive symptoms are both highly prevalent among patients with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) as well as breast cancer survivors. This study aimed to assess and directly compare perceptions of fatigue as highly interfering in one's daily functioning in both patient populations to better understand their relationships with depressed mood. Participants were 95 female CFS/ME patients and 67 females who were approximately 5 years post-treatment for stage 0-III breast cancer presenting with clinically elevated fatigue severity. Self-report measures were obtained on participants' fatigue-related interference in daily functioning and fatigue severity as well as depressed mood. Hierarchical regression was used to test effects controlling for relevant demographic, psychosocial, and medical covariates. CFS/ME patients endorsed greater depressed mood and fatigue interference than did fatigued breast cancer survivors, p's fatigued breast cancer survivors (β=.18, p =.19). CFS/ME patients reported elevated fatigue symptoms and depression relative to fatigued breast cancer survivors. In the former group, greater depressed mood was highly and significantly associated with greater fatigue-related inference in daily activities. Potential targets for cognitive behavioral interventions are discussed.

    Guidelines suggest that aerobic endurance training and moderate resistance training lessen the effects of cancer-related fatigue (CRF). However, specifics regarding frequency, intensity, and type of physical activity required to alleviate fatigue are less specific. In addition, outcomes of these interventions during the initial stages of active treatment are not well documented. The purpose of this article is to review the current evidence-based literature regarding the effects of physical exercise on CRF and the role that the clinical nurse leader (CNL) can play in implementing interventions to address CRF and promote physical exercise to improve patient outcomes. A literature review of the effect of physical exercise on CRF was conducted using the CINAHL®, PubMed, and Google Scholar databases. As leaders in health care, CNLs have the knowledge and skill to take an active role in managing CRF and to develop evidence-based interventions to address fatigue in this patient population. Interventions may include creating and evaluating individualized exercise plans for inpatients with cancer and/or developing educational programs for the inpatient setting that may be continued after discharge and during outpatient treatment.

    Purpose Cancer-related fatigue occurs frequently in patients with Hodgkin lymphoma (HL) and has a major impact on their quality of life. We hypothesized that severe fatigue (sFA) might have an impact on patients' treatment outcome and social reintegration. Methods Of 5,306 patients enrolled in the German Hodgkin Study Group's fifth generation of clinical trials in HL (HD13, HD14, and HD15; nonqualified and older [> 60 years] patients excluded), 4,529 provided data on health-related quality of life. We describe sFA (defined as a score ≥ 50 on the 0 to 100 scale from the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30) before and up to 9 years after therapy and analyze its impact on treatment outcome and social reintegration. Results The proportion of patients reporting sFA was 37% at baseline and ranged from 20% to 24% during follow-up. Baseline sFA was associated with significantly impaired progression-free survival and a trend to impaired overall survival, which can be overcome in patients receiving highly effective HL therapies as applied in our fifth-generation trials. Our analysis revealed a significant negative association of sFA and employment in survivors: 5 years after therapy, 51% and 63% of female and male survivors, respectively, with sFA were working or in professional education, compared with 78% and 90% without sFA, respectively ( P financial problems and the number of visits to a general practitioner and medical specialists. Conclusion sFA is an important factor preventing survivors from social reintegration during follow-up. This observation underscores the need to address fatigue as a significant diagnosis when treating patients with and survivors of cancer.

    We investigated the difference in relationship between muscle strength and quality of life (QOL)/fatigue in long-term cancer survivors and healthy subjects. Thirty-six cancer survivors and 29 healthy subjects were assessed for body composition and bone status at the calcaneus using the Osteo Sono Assessment Index. Muscle strength was evaluated via handgrip and knee extensor strength. Health-related QOL was assessed using the Medical Outcome Study 36-item Short-Form Health Survey. Fatigue was measured using the brief fatigue inventory. Cancer survivors exhibited lower QOL scores in the physical functioning, physical role function, bodily pain and general health domains (p < .05). Grip and knee extension muscle strength in cancer survivors was positively correlated with the physical function and bodily pain of QOL (p < .05). The usual fatigue subscale score was only significantly higher in cancer survivors than in healthy subjects (p < .05). However, there were no correlations between muscle strength and fatigue in cancer survivors. Our results showed that muscle strength was an important factor for improving QOL in cancer survivors. We believe that the findings of this study will be relevant in the context of planning rehabilitation for cancer survivors. © 2018 John Wiley & Sons Ltd.

    Full Text Available Abstract Background It remains unclear whether estrogenic botanical supplement (EBS use influences breast cancer survivors' health-related outcomes. Methods We examined the associations of EBS use with health-related quality of life (HRQOL, with fatigue, and with 15 hormone-related symptoms such as hot flashes and night sweats among 767 breast cancer survivors participating in the Health, Eating, Activity, and Lifestyle (HEAL Study. HRQOL was measured by the Medical Outcomes Study short form-36 physical and mental component scale summary score. Fatigue was measured by the Revised-Piper Fatigue Scale score. Results Neither overall EBS use nor the number of EBS types used was associated with HRQOL, fatigue, or hormone-related symptoms. However, comparisons of those using each specific type of EBS with non-EBS users revealed the following associations. Soy supplements users were more likely to have a better physical health summary score (odds ratio [OR] = 1.66, 95% confidence interval [CI] = 1.02-2.70. Flaxseed oil users were more likely to have a better mental health summary score (OR = 1.76, 95% CI = 1.05-2.94. Ginseng users were more likely to report severe fatigue and several hormone-related symptoms (all ORs ≥ 1.7 and all 95% CIs exclude 1. Red clover users were less likely to report weight gain, night sweats, and difficulty concentrating (all OR approximately 0.4 and all 95% CIs exclude 1. Alfalfa users were less likely to experience sleep interruption (OR = 0.28, 95% CI = 0.12-0.68. Dehydroepiandrosterone users were less likely to have hot flashes (OR = 0.33, 95% CI = 0.14-0.82. Conclusions Our findings indicate that several specific types of EBS might have important influences on a woman's various aspects of quality of life, but further verification is necessary.

    Fatigue is one of the most prevalent and profound symptoms related to both malignancy and anti-neoplastic treatment. It is being reported in 60% to 80% of cancer patients. We review the correlation between the cancer-related fatigue syndrome and radiotherapy. In patients undergoing radiotherapy, fatigue is often cumulative and may reach its peak during the last weeks of treatment. The presence of fatigue prior to therapy initiation is the most important predictive factor of the occurrence of radiotherapy-related cancer fatigue syndrome. Occasionally, fatigue persists for a prolonged period of months and even years beyond radiotherapy. Anemia may be one of major causative factors responsible for the development of the cancer-related fatigue syndrome. Fatigue has an enormous physical, mental, emotional, and economic impact on cancer patients, their families and care-providers. The treatment of radiation-related fatigue remains unknown. The initial approach should cover efforts aimed at the correction of potential etiologies, especially anemia. Education concerning fatigue greatly benefits some patients. It seems that exercise may be beneficial in relieving fatigue, bearing in mind that the exercise program for cancer patients should be initiated gradually and significantly individualized. (author)

    Cancer-related fatigue is one of the most prevalent, prolonged and distressing side effects of prostate cancer treatment with androgen deprivation therapy. Preliminary evidence suggests natural therapies such as nutrition therapy and structured exercise prescription can reduce symptoms of cancer-related fatigue. Men appear to change their habitual dietary patterns after prostate cancer diagnosis, yet prostate-specific dietary guidelines provide limited support for managing adverse side effects of treatment. The exercise literature has shown high intensity interval training can improve various aspects of health that are typically impaired with androgen deprivation therapy; however exercise at this intensity is yet to be conducted in men with prostate cancer. The purpose of this study is to examine the effects of nutrition therapy beyond the current healthy eating guidelines with high intensity interval training for managing cancer-related fatigue in men with prostate cancer treated with androgen deprivation therapy. This is a two-arm randomized control trial of 116 men with prostate cancer and survivors treated with androgen deprivation therapy. Participants will be randomized to either the intervention group i.e. nutrition therapy and high intensity interval training, or usual care. The intervention group will receive 20 weeks of individualized nutrition therapy from an Accredited Practising Dietitian, and high intensity interval training (from weeks 12-20 of the intervention) from an Accredited Exercise Physiologist. The usual care group will maintain their standard treatment regimen over the 20 weeks. Both groups will undertake primary and secondary outcome testing at baseline, week 8, 12, and 20; testing includes questionnaires of fatigue and quality of life, objective measures of body composition, muscular strength, cardiorespiratory fitness, biomarkers for disease progression, as well as dietary analysis. The primary outcomes for this trial are measures of

    To translate and validate the Cancer-Related Fatigue (CRF) Scale in the Greek language. A cross-sectional descriptive design was used in order to translate and validate the CRF Scale in Greek. Factor analyses were performed to understand the psychometric properties of the scale and to establish construct, criterion and convergent validity. Outpatients' oncology clinics of two public hospitals in Cyprus. 148 patients with advanced prostate cancer undergoing chemotherapy. The Cancer Fatigue Scale (CFS) had good stability (test-retest reliability r=0.79, pKaiser-Meyer-Olkin Measure of Sampling Adequacy (KMO value) was found to be 0.743 and considered to be satisfactory (>0.5). The correlations between the CFS physical scale (CFS-FS scale) and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 physical subscales were found to be significant (r=-0.715). The same occurred between CFS cognitive and EORTC cognitive subscale (r=-0.579). Overall, the criterion validity was verified. The same occurs for the convergent validity of the CFS since all correlations with the Global Health Status (q29-q30) were found to be significant. This is the first validation study of the CRF Scale in Greek and warrant of its use in the assessment of prostate cancer patient's related fatigue. However, further testing and validation is needed in the early stages of the disease and in patients in later chemotherapy cycles. Published by the BMJ Publishing Group Limited.

    This quasi-experimental and cross-sectional study was carried out to determine the efficacy of back massage, a nursing intervention, on the process of acute fatigue developing due to chemotherapy and on the anxiety level emerging in cancer patients receiving chemotherapy during this process. The study was conducted on 40 patients. To collect the data, the Personal Information Form, the State Anxiety part of Spielberger State-Trait Anxiety Inventory and the Brief Fatigue Inventory were used. In our study, it was determined that mean anxiety scores decreased in the intervention group patients after chemotherapy. The level of fatigue in the intervention group decreased statistically significantly on the next day after chemotherapy (p=.020; effect size=0.84). At the same time, the mean anxiety scores of the patients in the intervention group decreased right after the massage provided during chemotherapy (p=.109; effect size=0.37) and after chemotherapy. In line with our study findings, it can be said that back massage given during chemotherapy affects anxiety and fatigue suffered during the chemotherapy process and that it significantly reduces state anxiety and acute fatigue. Therefore, the effective use of back massage in the process of chemotherapy by oncology nurses who have a key role in cancer treatment and care can make it more modulated. © 2013.

    Fatigue is a prevalent source of suffering in children with advanced cancer; yet, little is known about it. This study aimed to describe fatigue experienced by children with advanced cancer and to identify the factors associated with suffering from fatigue and its treatment. A retrospective cross-sectional study of 141 parents of children who died of cancer (response rate: 64%) was conducted in two tertiary-level U.S. pediatric hospitals. By parent report, 96% of children experienced fatigue in the last month of life. Nearly 50% experienced significant suffering from fatigue; this was associated with suffering from pain, dyspnea, anorexia, nausea/vomiting, diarrhea, anxiety, sadness, or fear (Pfear (OR=5.13, 95% CI=2.03-12.96, P ≤ 0.001) remained independently associated with fatigue. Children suffering from fatigue had primary oncologists with fewer years' experience than children who did not suffer from fatigue (mean=7.7 years, standard deviation [SD]=4.9 vs. mean of 9.9 years, SD=6.0, P=0.02). Among children with fatigue, 17 of 129 (13%) received fatigue-directed treatment, which was successful in 3 of 12 (25%). Children experiencing side effects from dyspnea or pain treatment were more likely to be treated for fatigue (relative risk=1.25, 95% CI=1.06-1.47, P=0.009). Fatigue is a common source of suffering in children with cancer at the end of life. Palliation of this symptom is rarely successful. Increased attention to factors associated with fatigue and effective interventions to ameliorate fatigue are needed. Copyright © 2010 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc.

    Full Text Available Fatigue is a common symptom of advanced cancer limiting one′s activity and affecting the quality of life. It is a multidimensional symptom complex with subjective and objective components. Hence, its definition and assessment seems arbitrary, incomplete, and elusive. Components of fatigue often merge with other ′disease states′ as anemia, depression and so on, compounding difficulty to assess it separately. Fatigue has a high prevalence rate, and lasts longer in chronic diseases like cancer. Its association with treatment modalities like chemotherapy, radiotherapy alongside the primary disease process makes it seemingly ubiquitous in many cases. Systemic manifestation of cancer causes excess demand on body resources on cell repair, uncontrolled growth with metabolite accumulation causing fatigue. Co-morbid conditions of organic and psychological nature causes fatigue. There are many assessment tools for fatigue with different uses and objectives, simple and reproducible tools like Brief Fatigue Inventory, Edmonton Symptom assessment scale seem feasible in everyday practice. Management of fatigue is not straightforward and rewarding. Although treatment of cause appears to be an attractive option, it is not possible in all cases. Therapeutic agents targeting cytokine load is in early stages of study and available results are not favorable. Specific measures aimed at pain relief, prevention/treatment of sepsis, management of depression, avoidance of drugs causing fatigue, restoring the metabolic profile are important. Methyl phenidate, megestrol, and modafinil are some drugs with promising effect to treat fatigue, though confirmatory studies are yet to be established. Non-pharmacological methods are also helpful. Forewarning patients on upcoming fatigue, active regular exercise, and stress management are some of them. Fatigue being a multidimensional entity, single mode of therapy is insufficient. Combined modality tailored to individual

    Approximately one third of all patients who have been successfully treated for cancer suffer from chronic cancer-related fatigue (CCRF). Effective and easily accessible interventions are needed for these patients. The current paper reports on the results of a 3-armed randomized controlled trial investigating the clinical effectiveness of two different guided Web-based interventions for reducing CCRF compared to an active control condition. Severely fatigued cancer survivors were recruited via online and offline channels, and self-registered on an open-access website. After eligibility checks, 167 participants were randomized via an embedded automated randomization function into: (1) physiotherapist-guided Ambulant Activity Feedback (AAF) therapy encompassing the use of an accelerometer (n=62); (2) psychologist-guided Web-based mindfulness-based cognitive therapy (eMBCT; n=55); or (3) an unguided active control condition receiving psycho-educational emails (n=50). All interventions lasted nine weeks. Fatigue severity was self-assessed using the Checklist Individual Strength - Fatigue Severity subscale (primary outcome) six times from baseline (T0b) to six months (T2). Mental health was self-assessed three times using the Hospital Anxiety and Depression Scale and Positive and Negative Affect Schedule (secondary outcome). Treatment dropout was investigated. Multiple group latent growth curve analysis, corrected for individual time between assessments, showed that fatigue severity decreased significantly more in the AAF and eMBCT groups compared to the psycho-educational group. The analyses were checked by a researcher who was blind to allocation. Clinically relevant changes in fatigue severity were observed in 66% (41/62) of patients in AAF, 49% (27/55) of patients in eMBCT, and 12% (6/50) of patients in psycho-education. Dropout was 18% (11/62) in AAF, mainly due to technical problems and poor usability of the accelerometer, and 38% (21/55) in eMBCT, mainly due to

    Chronic fatigue after treatment is a common adverse event in cancer patients, but there are few studies in long-term survivors of cervical cancer. The aim of this investigation was to explore the prevalence of chronic fatigue and its association with various clinical and treatment-related factors in a population-based cohort of Norwegian cervical cancer survivors treated by any modality. All patients, treated for cervical cancer from 2000 through 2007 in the Health Region of South-Eastern Norway, cancer-free, alive and aged ≤75years by the end 2013 (n=822) received a questionnaire covering chronic fatigue and other clinical variables. 461 of 822 survivors (56%) completed the questionnaire and 382 entered the analyses. Chronic fatigue was reported by 23% (95% confidence interval 19%-27%) with a median age of 52years (range 32-75) at survey, 11years (range 7-15) after diagnosis. Among survivors treated by minimal invasive- or radical surgery, 19% had chronic fatigue, while the prevalence was 28% in those treated with radiation and concomitant chemotherapy (chemoradiation). The chronic fatigue group reported significantly more cardiovascular disease, obesity, less physical activity, more treatment-related symptom experience, more menopausal symptoms, higher levels of anxiety and depressive symptoms, and poorer quality of life than the non-fatigued group. In multivariate analysis only increased level of depression and poorer global quality of life were significantly associated with chronic fatigue. Chronic fatigue was reported by 23% of long-term survivors after cervical cancer at a mean of 11years after treatment. Some of the associated factors are amenable to prevention and/or treatment and should be subjects of attention at follow-up. Copyright © 2017 Elsevier Inc. All rights reserved.

Regarding quality of life (EORTC QLQ-C30 a direct effect (t0 to t1; p<0.001 of YI was found on role and emotional functioning, while under PEI only emotional functioning improved. Significant improvements (p<0.001 were observed at both t1 and t2 also for symptom scales in both groups: dyspnea, appetite loss, constipation, and diarrhea. There was no significant difference between therapies for none of the analyzed variables neither for t1 nor for t2. During chemotherapy, yoga was not seen as more helpful than conventional therapeutic exercises. This does not argue against its use in the recovery phase.

    Clinical trials that might identify effective therapies for cancer-related fatigue, one of the most distressing symptoms experienced by patients, require a validated fatigue assessment tool. We developed and validated a Filipino language version of the Brief Fatigue Inventory (BFI-F) for describing the prevalence and severity of fatigue among Filipino patients with cancer. We conducted a cross-sectional study in Manila, Philippines, in 206 patients with cancer and 170 age-matched community-dwelling adults who had never had a diagnosis of cancer. Validity and reliability were evaluated by principal factor analysis and Cronbach's α coefficients. Factor analysis extracted 1 factor, i.e. fatigue severity, with a Cronbach's α of 0.95; this is consistent with the original BFI English version validation study. Approximately 49% of the patients with cancer had mild fatigue, 34% had moderate fatigue, and 17% had severe fatigue. Patients with a poorer performance status had significantly worse fatigue than patients with a better performance status (5.0 ± 2.8 vs. 3.8 ± 2.2; p Filipino cancer patients. Copyright © 2010 S.

    Purpose Fatigue is a common adverse effect of cancer treatment and may persist for years after treatment completion. However, risk factors for post-treatment fatigue have not been determined. On the basis of studies suggesting an inflammatory basis for fatigue, this study tested the hypothesis that expression-regulating polymorphisms in proinflammatory cytokine genes would predict post-treatment fatigue in breast cancer survivors. Patients and Methods Women diagnosed with early-stage breast cancer (n = 171) completed questionnaires to assess fatigue and other behavioral symptoms (ie, depressive symptoms, memory complaints, sleep disturbance) and provided blood for genotyping within 3 months after primary treatment. Genomic DNA was extracted from peripheral-blood leukocytes and assayed for single nucleotide polymorphisms (SNPs) in the promoter regions of three cytokine genes: ILB −511 C>T (rs16944), IL6 −174 G>C (rs1800795), and TNF −308 G>A (rs1800629). An additive genetic risk score was computed by summing the number of high-expression alleles (zero, one, or two) across all three polymorphisms. Results The genetic risk index was significantly associated with fatigue; as the number of high-expression alleles increased, so did self-reported fatigue severity (P = .002). Analyses of individual SNPs showed that TNF −308 and IL6 −174 were independently associated with fatigue (P = .032). The genetic risk index was also associated with depressive symptoms (P = .007) and memory complaints (P = .016). Conclusion These findings further implicate inflammatory processes as contributors to cancer-related fatigue and suggest a new strategy for identifying and treating patients at risk for this symptom based on genetic variants in proinflammatory cytokine genes.

    Workers diagnosed with cancer are at risk for job loss or work disability. To determine predictors of fatigue and work ability at 36 months after diagnosis in a population of cancer survivors. Individuals diagnosed with cancer and who applied for work disability benefit at 24 months of sick leave were surveyed at the time of application and again 12 months later. Fatigue was measured using the Functional Assessment of Chronic Illness-Fatigue scale questionnaire and work ability was measured using the work ability index. Linear regression analyses were applied to identify predictors. There were 336 participants. Participants who were divorced or widowed had more physical limitations, more depressive symptoms and were more fatigued at baseline, and who worked in health care demonstrated higher levels of fatigue. Lower fatigue was predicted by having received chemotherapy. A higher level of work ability was predicted by having received chemotherapy, better global health and better work ability at baseline. Lower work ability was predicted by being principal wage earner, insecurity about being free of disease, having more physical limitations and having greater wage loss. Socio-demographic, health- and work-related factors were associated with fatigue and work ability in cancer survivors on long-term sick leave. As fatigue and poor work ability are important risk factors for work disability, addressing the identified predictive factors may assist in mitigation of work disability in cancer survivors. © The Author 2017.

    The goal of this study was to characterize changes in daily fatigue in women undergoing chemotherapy for breast cancer. We examined whether there are subgroups of patients with distinct fatigue trajectories and explored potential psychosocial and biomedical predictors of these subgroups. Participants were 77 women with breast cancer receiving adjuvant chemotherapy with AC-T (2-week cycle) and TC or TCH (3-week cycle) regimens. They completed 28 daily ratings online using an adapted version of the Patient-Reported Outcomes Measurement Information System (PROMIS®) fatigue instrument. Both regimens followed an "inverted-U-shaped" fatigue pattern over approximately 2 weeks. Growth mixture modeling identified three patient subgroups with distinct trajectories. Fatigue scores in the "low fatigue" group (23 %) increased following the infusion and quickly abated. The "transient fatigue" (27 %) group had a very pronounced increase. Patients in the "high fatigue" (50 %) group reported consistently elevated fatigue with a relatively small increase. Demographic and medical variables were not associated with fatigue trajectory. Patients in the "high fatigue" group reported significantly poorer physical, emotional, and social functioning, poorer general health, and more depressed mood than patients in the "low fatigue" group. The "transient fatigue" group reported significantly better physical and social functioning than the "high fatigue" group, but emotional distress and depression similar to the "high fatigue" group. The identification of patient subgroups with distinct fatigue trajectories during chemotherapy is an essential step for developing preventative strategies and tailored interventions. Our results suggest that different trajectories are associated with patients' psychosocial and general health.

    Breast cancer patients undergoing adjuvant chemotherapy often develop fatigue from their treatment that may persist for months. While the positive effects of physical activity in cancer patients are increasingly recognized, the impact of obesity on chemotherapy-induced fatigue has not been well studied. Female age 35-75 years with stage I-III breast cancer receiving adjuvant chemotherapy were enrolled in an IRB-approved study. Patient fatigue was self-reported using a 14-question fatigue symptom inventory. Patients were queried about fatigue and their level of exercise before, during, and after completion of chemotherapy. BMI was measured prior to their first cycle of chemotherapy. Of the 47 evaluable patients, 37 reported performing exercise on a regular basis. Following chemotherapy, 53 % of the exercise group and 80 % of the non-exercise group displayed a worsening of their FS. In patients with a BMI exercise group versus 40.5 in the non-exercise group. In patients with a BMI > 25, the FS after chemotherapy was 25.96 in the exercise group versus 32.6 in the non-exercise group. Our study indicates a trend towards fatigue reduction with exercise even in patients who are overweight. Thus, an elevated BMI at diagnosis does not preclude a breast cancer patient from experiencing the same positive effects from exercise on chemotherapy-related fatigue as patients with normal BMIs. This indicates an important role of physicians in the primary care setting to encourage patients to initiate physical activity when offering cancer-screening services.

    Full Text Available Background: Cancer-related fatigue (CRF is the most commonly reported and most distressing symptom in cancer patients. Health-related quality of life (QOL is an important outcome in cancer management, the authors sought to better understand its determinants. Aim: This study aims to identify quality of life and fatigue levels and the affecting factors in gynaecologic cancer patients. Method: This descriptive and cross-sectional study was conducted with 154 volunteer women with gynaecologic cancer. The data were collected through the interview form, functional assessment of cancer therapy-general (FACT-G Quality of Life Scale, and Piper Fatigue Scale. Results: The mean score of total quality of life in gynaecologic cancer patients was low, 53.4 ± 15.4. Physical and emotional states were found to be the mostly affected states in the quality of life. According to the Piper Fatigue Scale, the total fatigue score was mild, 3.5 ± 2.4. Total fatigue scores were found to be high in metastatic cancers. Multivariate analyses indicate that the most important factor affecting the quality of life is economic condition, and the most important variables affecting fatigue are the level of activity and use of medicine. Conclusion: This study found that quality of life dimensions in women with gynaecologic cancer was affected by factors such as cancer type, time of diagnosis, and stage and spread of the cancer.

    Androgen deprivation therapy (ADT) often worsens fatigue in patients with prostate cancer, producing symptoms similar to chronic fatigue syndrome (CFS). Comparing expression (mRNA) of many fatigue-related genes in patients with ADT-treated prostate cancer versus with CFS versus healthy controls, and correlating mRNA with fatigue severity may clarify the differing pathways underlying fatigue in these conditions. Quantitative real-time PCR was performed on leukocytes from 30 fatigued, ADT-treated prostate cancer patients (PCF), 39 patients with CFS and 22 controls aged 40-79, together with ratings of fatigue and pain severity. 46 genes from these pathways were included: (1) adrenergic/monoamine/neuropeptides, (2) immune, (3) metabolite-detecting, (4) mitochondrial/energy, (5) transcription factors. PCF patients showed higher expression than controls or CFS of 2 immune transcription genes (NR3C1 and TLR4), chemokine CXCR4, and mitochondrial gene SOD2. They showed lower expression of 2 vasodilation-related genes (ADRB2 and VIPR2), 2 cytokines (TNF and LTA), and 2 metabolite-detecting receptors (ASIC3 and P2RX7). CFS patients showed higher P2RX7 and lower HSPA2 versus controls and PCF. Correlations with fatigue severity were similar in PCF and CFS for only DBI, the GABA-A receptor modulator (r=-0.50, pfatigue and pain severity (r=+0.43 and +0.59, p=0.025 and p=0.001). PCF patients differed from controls and CFS in mean expression of 10 genes from all 5 pathways. Correlations with fatigue severity implicated DBI for both patient groups and P2RY1 for PCF only. These pathways may provide new targets for interventions to reduce fatigue. Copyright © 2013 Elsevier Ltd. All rights reserved.

  18. Implementation of evidence into practice for cancer-related fatigue management of hospitalized adult patients using the PARIHS framework.

    Full Text Available This study aimed to explore an evidence-based nursing practice model of CRF management in hospitalized adult patients using the PARIHS evidence-implementation framework as the theoretical structure to provide guidance for similar nursing practices. The implementation of guideline evidence into clinical practice was conducted on the oncology and radiotherapy wards of a university-affiliated hospital. The process of integrating the guideline into the symptom management system of cancer patients was described. The impact of the evidence implementation was evaluated from three aspects: organizational innovations and outcome measures associated with nurses and with patients pre- and post-evidence implementation. During the implementation of evidence into practice on the wards, a nursing process, health education, a quality control sheet and CRF training courses were established. Through this implementation, compliance with evidence related to CRF increased significantly on the two wards, with that of ward B being higher than that of ward A. Regarding nursing outcomes, nursing knowledge, attitude and behavior scores with respect to CRF nursing care increased substantially after its application on the two wards, and the ward B nurses' scoring was higher than that of the ward A nurses. Qualitative analysis concerning the nurses suggested that leadership, patient concern about CRF management, and the need for professional development were the main motivators of the application, whereas the shortage and mobility of nursing human resources and insufficient communication between doctors and nurses were the main barriers. Additionally, most nurses felt more professional and confident about their work. Regarding patient outcomes, patient knowledge, attitude and behavior scores regarding CRF self-management increased significantly. Patients' post-implementation CRF was alleviated compared with the pre-implementation treatment cycle. The PARIHS framework may

    Psychosocial and inflammatory factors have been associated with fatigue in breast cancer survivors. Nevertheless, the relative contribution and/or interaction of these factors with cancer-related fatigue have not been well documented. This cross-sectional study enrolled 111 stage 0-III breast cancer patients treated with breast surgery followed by whole breast radiotherapy. Fatigue was measured by the total score of the Multidimensional Fatigue Inventory-20. Potential risk factors included inflammatory markers (plasma cytokines and their receptors and C-reactive protein; CRP), depressive symptoms (as assessed by the Inventory of Depressive Symptomatology-Self Reported), sleep (as assessed by the Pittsburgh Sleep Quality Index) and perceived stress (as assessed by the Perceived Stress Scale) as well as age, race, marital status, smoking history, menopause status, endocrine treatment, chemotherapy and cancer stage. Linear regression modeling was employed to examine risk factors of fatigue. Only risk factors with a significance level fatigue. At 1 year post-radiotherapy, depressive symptoms (pfatigue. Mediation analysis showed that depressive symptoms also mediated the associations of fatigue with sleep and stress. Depressive symptoms and inflammation were independent risk factors for cancer-related fatigue at 1 year post-radiotherapy, and thus represent independent treatment targets for this debilitating symptom.

    Regorafenib is an oral multikinase inhibitor with a proven survival benefit for metastatic colorectal cancer patients. The KSCC1402/HGCSG1402 study investigated the prophylactic effect of oral dexamethasone (DEX) on regorafenib-related fatigue and/or malaise. Patients who progressed after standard chemotherapy were randomized 1: 1 to a DEX group (2 mg/day; days 1-28) with regorafenib or a placebo group with regorafenib. The primary endpoint was the incidence of fatigue and/or malaise, based on version 4.0 of the National Cancer Institute's CTCAE (Common Terminology Criteria for Adverse Events). One of the secondary endpoints was the in-cidence of fatigue and/or malaise based on the CTCAE assessed by patient-reported outcome (PRO). The incidence of any grade of fatigue and/or malaise assessed by the investigators was 58.8% in the DEX group and 61.1% in the placebo group (p = 0.8101), and that assessed by PRO was 47.2 and 58.3%, respectively (p = 0.3450). The incidence of grade ≥2 fatigue and/or malaise, as assessed by the investigators, was 19.4% for the DEX group and 38.9% for the placebo group (p = 0.0695), and that assessed by PRO was 27.8 and 52.8%, respectively (p = 0.0306). Our results suggest that prophylactic oral DEX is clinically effective in improving regorafenib-related fatigue and/or malaise. © 2018 S. Karger AG, Basel.

    Cancer-related fatigue is a common complaint during cancer treatment and is often associated with cognitive impairment. This study examined cognitive deficits that were associated with fatigue symptoms during external-beam radiation therapy (EBRT) in men with localized prostate cancer. A total of 36 participants were enrolled and followed up at baseline, 24 h, 7 days, 14 days after EBRT initiation, at midpoint, and at completion of EBRT. Fatigue was measured by self-report using the Functional Assessment of Cancer Therapy - Fatigue (FACT-F), and cognitive impairment by the Computer Assessment of Mild Cognitive Impairment (CAMCI®). Subjects with increased fatigue during EBRT reported a significant decline in cognitive function and had difficulties with CAMCI®'s route finding and item recall tasks during EBRT. Increased fatigue during EBRT was associated with perceived cognitive difficulties in executive function and recognition memory, but not with attention or verbal memory. Our results suggest that there might be specific cognitive domains that are associated with increased fatigue during EBRT. These findings will provide important information for targeting specific cognitive domains using pharmacotherapy or behavioral interventions. CAMCI® is a valuable tool for psycho social providers to detect subtle cognitive impairment in fatigued cancer patients in a clinical setting. © 2018 S. Karger AG, Basel.

    Fatigue is one of the most common and disabling symptoms in Parkinson's disease (PD). Since fatigue was first described as a common feature of PD 20 years ago, little progress has been made in understanding its causes or treatment. Importantly, PD patients attending the 2013 World Parkinson Congress voted fatigue as the leading symptom in need of further research. In response, the Parkinson Disease Foundation and ProjectSpark assembled an international team of experts to create recommendations for clinical research to advance this field. The working group identified several areas in which shared standards would improve research quality and foster progress including terminology, diagnostic criteria, and measurement. Terminology needs to (1) clearly distinguish fatigue from related phenomena (eg, sleepiness, apathy, depression); (2) differentiate subjective fatigue complaints from objective performance fatigability; and (3) specify domains affected by fatigue and causal factors. We propose diagnostic criteria for PD-related fatigue to guide participant selection for clinical trials and add rigor to mechanistic studies. Recommendations are made for measurement of subjective fatigue complaints, performance fatigability, and neurophysiologic changes. We also suggest areas in which future research is needed to address methodological issues and validate or optimize current practices. Many limitations in current PD-related fatigue research may be addressed by improving methodological standards, many of which are already being successfully applied in clinical fatigue research in other medical conditions (eg, cancer, multiple sclerosis). © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

    Cancer-related fatigue (CRF) reduces quality of life and the activity level of patients with cancer. Cancer related fatigue can be reduced by exercise interventions that may concurrently increase muscle mass. We hypothesized that low muscle mass is directly related to higher CRF. A total of 233 patients with advanced cancer starting palliative chemotherapy for lung, colorectal, breast, or prostate cancer were studied. The skeletal muscle index (SMI) was calculated as the patient's muscle mass on level L3 or T4 of a computed tomography scan, adjusted for height. Fatigue was assessed with the Functional Assessment of Chronic Illness Therapy-fatigue questionnaire (cut-off for fatigue fatigue score was 36 (interquartile range 26-44). A higher SMI on level L3 was significantly associated with less CRF for men (B 0.447, P 0.004) but not for women (B - 0.401, P 0.090). No association between SMI on level T4 and the Functional Assessment of Chronic Illness Therapy-fatigue score was found (n = 82). The association between SMI and CRF may lead to the suggestion that male patients may be able to reduce fatigue by exercise interventions aiming at an increased muscle mass. In women with advanced cancer, CRF is more influenced by other causes, because it is not significantly related to muscle mass. To further reduce CRF in both men and women with cancer, multifactorial assessments need to be performed in order to develop effective treatment strategies. © 2017 The Authors.

    Fatigue is highly prevalent in the general population and is one of the most common side effects of cancer treatment. There is growing evidence that pro-inflammatory cytokines play a role in cancer-related fatigue, although the molecular mechanisms for chronic inflammation and fatigue have not been determined. The current study utilized genome-wide expression microarrays to identify differences in gene expression and associated alterations in transcriptional activity in leukocytes from breast cancer survivors with persistent fatigue (n = 11) and non-fatigued controls (n = 10). We focused on transcription of inflammation-related genes, particularly those responsive to the pro-inflammatory NF-κB transcription control pathway. Further, given the role of glucocorticoids as key regulators of inflammatory processes, we examined transcription of glucocorticoid-responsive genes indicative of potential glucocorticoid receptor (GR) desensitization. Plasma levels of cortisol were also assessed. Consistent with hypotheses, results showed increased expression of transcripts with response elements for NF-κB, and reduced expression of transcripts with response elements for glucocorticoids (p < .05) in fatigued breast cancer survivors. No differences in plasma levels of cortisol were observed. These data indicate that increased activity of pro-inflammatory transcription factors may contribute to persistent cancer-related fatigue and provide insight into potential mechanisms for tonic increases in NF-κB activity, specifically decreased expression of GR anti-inflammatory transcription factors.

    Human papillomavirus (HPV) infection has contributed to an increased incidence of squamous cell carcinoma of the head and neck (SCCHN). Fatigue is a major side effect of SCCHN and its treatment. However, to the authors' knowledge, the association between HPV and fatigue has not been examined to date, nor is it known whether HPV influences biological mechanisms of fatigue, including inflammation. Patients with SCCHN who were without distant metastasis were assessed at baseline (pre-radiotherapy) and 1 month and 3 months postradiotherapy. Fatigue was measured using the Multidimensional Fatigue Inventory. Peripheral inflammation was assessed by plasma C-reactive protein (CRP), interleukin 1 receptor antagonist (IL-1ra), soluble tumor necrosis factor receptor 2 (sTNFR2), and IL-6. Mixed effect models were used to examine associations. A total of 94 patients who were newly diagnosed were enrolled; 53% had HPV-related tumors. Patients with HPV-unrelated tumors had higher fatigue and higher plasma CRP, sTNFR2, and IL-6 over time, especially at baseline and 3 months after intensity-modulated radiotherapy compared with those with HPV-related tumors (all P < .05). However, fatigue and plasma sTNFR2 increased more significantly from baseline to 1 month after radiotherapy in the HPV-related group compared with the HPV-unrelated group (both P < .01). Controlling for significant covariates, HPV status and inflammation were found to be independent predictors of fatigue over time. HPV status is an important marker of vulnerability to the behavioral and immune consequences of SCCHN and its treatment, providing support for different symptom management strategies. Special emphasis should be placed on addressing marked persistent fatigue in patients with HPV-unrelated tumors, whereas attention should be paid to the large increases in fatigue during treatment among patients with HPV-related tumors.

    Anemia is the most common hematological abnormality in cancer patients is often under-recognized and undertreated. The pathogenesis of cancer anemia is complex and most of time multifactorial; involving factors related to the tumor itself or its therapy. While anemia can be present in a wide range of symptoms, involing almost every organ, it is beleived that it contributes much to cancer-related-fatigue, one of the most common symptoms in cancer patients. In addition there is increasing evidence to suggest that anemia is an independent factor adversely affecting tumor reponse and patient survival. While blood transfusion was the only option to treat cancer related anemia, the use of recombinant human erythropoietin (rHuEPO) is becomig the new standard of care, more so with the recent studies demonstrating the feasibility of a sigle weekly injection .Things are even getting better with the recent approval of a new form of rHuEPO; Darbepoetin an analogue with a 3-fold longer half-life. In addition to its effects in raising homoglobin, several well controlled studies demonstrated decrease in transfusion requirementsand better qualify of life assessed objectively using standard assesments scales.

    Full Text Available Background: Fatigue is a common side-effect of conventional prostate cancer radiation therapy. The increased delivery precision necessitated by the high dose per fraction of stereotactic body radiation therapy (SBRT offers the potential of reduce target volumes and hence the exposure of normal tissues to high radiation doses. Herein, we examine the level of fatigue associated with SBRT treatment.Methods: Forty patients with localized prostate cancer treated with hypofractionated SBRT, and a minimum of 12 months follow-up were included in this analysis. Self-reported fatigue and other quality of life measures were assessed at baseline and at 1, 3, 6, 9, and 12 months post-SBRT.Results: Mean levels of fatigue were elevated at 1 month post-SBRT compared to baseline values (p=0.02. Fatigue at the 3-month follow-up and later were higher but not statistically significantly different compared to baseline. African-American patients reported higher fatigue post-SBRT than Caucasian patients. Fatigue was correlated with hormonal symptoms as measured by the Expanded Prostate Cancer Index Composite (EPIC quality of life questionnaire, but not with urinary, bowel, or sexual symptoms. Age, co-morbidities, smoking, prostate specific antigen (PSA levels, testosterone levels, and tumor stage were not associated with fatigue. Conclusion: This is the first study to investigate fatigue as a side-effect of SBRT. In contrast to standard radiation therapy, results suggest SBRT-related fatigue is short-term rather than a long-term side effect of SBRT. These results also suggest post-SBRT fatigue to be a more frequent complication in African-Americans than Caucasians.

    stages of the cancer experience. Earlier studies suggest that many patients recover from fatigue after treatment completion. Patients with cancer experience disturbance in their personal goals, which is related to poor psychological well-being. What does this study add? Developments of fatigue and goal disturbance differ between subgroups of patients with cancer but co-occur within these subgroups. About 30% of the patients experience severe fatigue after diagnosis, of which only few patients recover within 18 months post-diagnosis. Targeting goal disturbance might benefit patients with severe and ongoing symptoms. © 2017 The British Psychological Society.

  14. Breast cancer and fatigue: issues for the workplace.

    1. Women with breast cancer are at high risk for fatigue as a side effect of treatment with surgery, radiation, and chemotherapy. The risk is compounded by the multiple roles of women who return to work during treatment. 2. The fatigue experience includes a physical component of decreased functional status, an affective component of emotional distress, and a cognitive component of difficulty concentrating. These characteristics of fatigue may present significant challenges for employees. 3. The Family Medical Leave Act provides 12 weeks of unpaid leave to receive medical treatment and/or recover from treatment for breast cancer. 4. The nurse in the workplace can assess and monitor the effects of fatigue and teach employees to manage fatigue through energy conservation, effective use of energy, and health promotion activities to restore energy levels.

    Background Fatigue is a common and distressing side effect of androgen deprivation therapy (ADT) for prostate cancer. The goal of the current study was to examine the relationship between changes in fatigue following initiation of ADT and single nucleotide polymorphisms (SNPs) in three pro-inflammatory cytokine genes: interleukin-1 beta (IL1B), interleukin-6 (IL6), and tumor necrosis factor alpha (TNFA). Methods As part of a larger study, men with prostate cancer (n=53) were recruited prior to initiation of ADT. Fatigue was assessed at recruitment and six months after initiation of ADT. DNA was extracted from blood drawn at baseline. Results Patients with the IL6-174 (rs1800795) G/C or C/C genotype displayed greater increases in fatigue intrusiveness, frequency, and duration than the G/G genotype (p values≤0.05), although inclusion of age, race, and baseline depressive symptomatology in the model attenuated these relationships (p values≤0.09). Patients with the TNFA-308 (rs1800629) G/A genotype showed greater increases in fatigue severity than the G/G genotype (p=0.02). IL1B-511 (rs16944) genotype did not significantly predict changes in fatigue (p values>0.46). Patients with higher numbers of variants displayed greater increases in fatigue duration and interference (p values≤0.02) than patients with lower numbers of variants. Conclusions Prostate cancer patients treated with ADT who carry variant alleles of the IL6 and TNFA genes are susceptible to heightened fatigue. These preliminary data lend support for the role of genetic variation in the development of cancer-related fatigue secondary to ADT. Findings are relevant to attempts to develop personalized approaches to cancer treatment. PMID:22475653

    The study purpose was to test the effectiveness of a psychological intervention combining cognitive-behavioral therapy and hypnosis (CBTH) to treat radiotherapy-related fatigue. Women (n = 42) scheduled for breast cancer radiotherapy were randomly assigned to receive standard medical care (SMC) (n = 20) or a CBTH intervention (n = 22) in addition to SMC. Participants assigned to receive CBTH met individually with a clinical psychologist. CBTH participants received training in hypnosis and CBT. Participants assigned to the SMC control condition did not meet with a study psychologist. Fatigue was measured on a weekly basis by using the fatigue subscale of the Functional Assessment of Chronic Illness Therapy (FACIT) and daily using visual analogue scales. Multilevel modeling indicated that for weekly FACIT fatigue data, there was a significant effect of the CBTH intervention on the rate of change in fatigue (p < .05), such that on average, CBTH participants' fatigue did not increase over the course of treatment, whereas control group participants' fatigue increased linearly. Daily data corroborated the analyses of weekly data. The results suggest that CBTH is an effective means for controlling and potentially preventing fatigue in breast cancer radiotherapy patients.

    Full Text Available Background: The purposes of this study were to examine the impact of chemotherapy treatment on Jordanian cancer patients’ fatigue and to correlate their fatigue with selected sociodemographic variables at the beginning of treatment and after four weeks of treatment. Methods: This was a single group quasi-experimental correlational design study that enrolled 43 patients diagnosed with cancer who required chemotherapy treatment. Fatigue was measured according to the Piper Fatigue Scale (PFS before starting chemotherapy treatment and after four weeks of receiving the first dose of chemotherapy. Data were collected over a period of four weeks and analyzed with descriptive statistics, the paired-sample t-test, and Pearson product-moment correlation. Results: The study included 17 (39.5% males and 26 (60.5% females with a mean age of 45.98 years. Most (n=17 were diagnosed with breast cancer. Obesity was present in about 64.4% of patients. The majority (46% received an anthracycline-based regimen. There were statistically significant differences between respondents’ total mean scores of fatigue pre-treatment and four weeks following chemotherapy treatment (t= -2.31, df=42, P<0.05. In addition, significant differences were found in the scores for behavioral, affective, sensory, and cognitive dimensions subscales (t= -2.24, -2.19, - 2.4, -2.4, df=42, P<0.05 between pre-treatment and four weeks after receiving the first dose of chemotherapy treatment. We observed a significant negative relationship between fatigue scores and hemoglobin levels (r= -0.04, P<0.01. Conclusion: Cancer-related fatigue is common among cancer patients who received chemotherapy and result in substantial adverse physical, behavioral, cognitive and affective consequences for patient. Given the impact of fatigue, treatment options should be routinely considered in the care of patients with cancer.

    Illness is experienced in social contexts; its meaning is rooted in local beliefs and values as well as one's personal and family situation. Health professionals are steeped in knowledge of disease but know much less about illness. The objective of the study was to learn more about the social construction of illness by comparing the meanings of fatigue in Thai and Canadian individuals with cancer. Using an ethnoscience design, 10 Thai adults receiving chemotherapy for advanced lung cancer or colorectal cancer were interviewed twice. They were asked to sort words and phrases about fatigue from their first interview using Q-sort, triadic, and dyadic approaches; to name each pile; and to describe the similarities and differences between the piles. The card sorts were used to understand the relationships among key ideas in each interview. A table summarizing the card sorts was constructed, and patterns in the data were identified. Two segregates in the Thai data were identified: essential/constant and intermittent, with essential/constant including 2 segregates (feeble and altered cognition), and intermittent including 2 segregates (loss of mental strength and difficulty sleeping). The primary meanings of fatigue in the Thai data were related to temporality, whereas the primary meanings of fatigue in the Canadian data were related to the location of the fatigue (mind/body). These findings help us understand the social construction of fatigue, a common symptom in cancer. Further research in relation to links between fatigue and other related-symptoms is needed with the goal of developing cross-cultural interventions for managing fatigue in the future.

    Background and purpose: Fatigue during head and neck radiotherapy may be related to radiation dose to the central nervous system (CNS). The impact of patient, tumour, and dosimetric variables on acute fatigue was assessed in nasopharyngeal cancer patients undergoing chemoradiotherapy. Material and methods: Radiation dose to the following retrospectively-delineated CNS structures; brainstem, cerebellum, pituitary gland, pineal gland, hypothalamus, hippocampus and basal ganglia (BG) and clinical variables were related to incidence of ⩾ grade 2 fatigue in 40 patients. Results: Sixty per cent of patients reported fatigue during and following radiotherapy. Dmean and D2 to the BG and Dmean to the pituitary gland were significantly associated with fatigue during radiation (P < 0.01). Dmean to the cerebellum was associated with fatigue following radiotherapy and at any time (P < 0.01). After adjusting for clinical factors, an association remained between fatigue during radiotherapy and mean dose and D2 to the pituitary gland and BG (P = 0.012, 0.036, 0.009 and 0.018) and mean dose to the cerebellum following radiation and at any time (P = 0.042 and 0.029). Conclusion: Disruption of connections between BG, cerebellum, and higher cortical centres or disruption of pituitary-regulated hormonal balance may be implicated in the pathophysiology of radiation-related fatigue

    This pilot study examined whether breast cancer patients with childhood trauma exhibit increased fatigue, depression, and stress in association with inflammation as a result of whole breast radiotherapy (RT). Twenty breast cancer patients were enrolled in a prospective, longitudinal study of fatigue, depression, and perceived stress prior to RT, week 6 of RT, and 6 weeks post-RT. Six weeks after RT, subjects completed the childhood trauma questionnaire (CTQ). Patients were also administered the multidimensional fatigue inventory, inventory of depressive symptomatology-self-reported, and perceived stress scale at all three time-points and underwent blood sampling prior to RT for gene expression and inflammatory markers previously associated with childhood trauma and behavioral symptoms in breast cancer patients. Eight subjects (40%) had past childhood trauma (CTQ+). Compared to CTQ- patients, CTQ+ patients had significantly higher fatigue, depression, and stress scores before, during, and after RT (p fatigue, and stress scores in CTQ+ but not CTQ- patients. Childhood trauma was prevalent and was associated with increased symptoms of fatigue, depression, and stress irrespective of RT. Increased symptoms in CTQ+ patients were also associated with baseline inflammatory markers. Treatments targeting childhood trauma and related inflammation may improve symptoms in breast cancer patients. Copyright © 2015 John Wiley & Sons, Ltd.

    Research on determinants of well-being in patients on thyroid hormone replacement therapy is warranted, as persistent fatigue-related complaints are common in this population. In this study, we evaluated the impact of different states of hypothyroidism on fatigue and fatigue-related symptoms. Furthermore, the relationship between fatigue and the TSH receptor (TSHR)-Asp727Glu polymorphism, a common genetic variant of the TSHR, was analyzed. A cross-sectional study was performed in 278 patients (140 patients treated for differentiated thyroid carcinoma (DTC) and 138 with autoimmune hypothyroidism (AIH)) genotyped for the TSHR-Asp727Glu polymorphism. The multidimensional fatigue inventory (MFI-20) was used to assess fatigue, with higher MFI-20 scores indicating more fatigue-related complaints. MFI-20 scores were related to disease status and Asp727Glu polymorphism status. AIH patients scored significantly higher than DTC patients on all five MFI-20 subscales (P<0.001), independent of clinical and thyroid hormone parameters. The frequency of the TSHR-Glu727 allele was 7.2%. Heterozygous DTC patients had more favorable MFI-20 scores than wild-type DTC patients on four of five subscales. The modest effect of the TSHR-Asp727Glu polymorphism on fatigue was found in DTC patients only. AIH patients had significantly higher levels of fatigue compared with DTC patients, which could not be attributed to clinical or thyroid hormone parameters. The modest effect of the TSHR-Asp727Glu polymorphism on fatigue in DTC patients should be confirmed in other cohorts.

    Purpose: To assess the level of fatigue during the course of adjuvant radiotherapy (RT) of breast cancer patients and its relation to anxiety, depression, serum cytokines, and blood count levels. Methods and Materials: Forty-one patients who received adjuvant RT after breast-conserving surgery were prospectively studied. All patients underwent RT without concomitant chemotherapy. Patients rated their fatigue with two standardized self-assessment instruments, the Fatigue Assessment Questionnaire and a visual analog scale on fatigue intensity, before RT, during weeks 1-5 of RT, and 2 months after RT completion. In addition, the anxiety and depression levels were assessed with the Hospital Anxiety and Depression Scale. A differential blood cell count and the serum levels of the cytokines interleukin (IL)-1β, IL-6, and tumor necrosis factor-α were determined in parallel to the fatigue assessments. Results: Fatigue intensity as assessed with the visual analog scale increased (p<0.001) until treatment week 4 and remained elevated until week 5. Two months after RT, the values had fallen to the pretreatment levels. Fatigue measured with the Fatigue Assessment Questionnaire did not increase significantly during treatment, but the subscores on physical (p=0.035) and cognitive (p=0.015) fatigue were elevated during treatment weeks 4 and 5. Affective fatigue did not change significantly. Anxiety, as rated with the Hospital Anxiety and Depression Scale, declined during RT (p=0.002), but the Hospital Anxiety and Depression Scale depression score did not change significantly. IL-1β, IL-6, and tumor necrosis factor-α levels did not change during therapy and did not correlate with fatigue. Peripheral blood cell levels declined significantly during therapy and were still low 2 months after treatment. Until treatment week 5, lymphocytes were reduced to almost 50% of their initial values. Hemoglobin levels did not correlate with fatigue. Conclusions: We observed an increase in

    Fatigue negatively affects the performance of intensive care nurses. Factors contributing to the fatigue experienced by nurses include lifestyle, psychological status, work organization and sleep problems. To determine the level of fatigue among nurses working in intensive care units and the related factors. This descriptive study was conducted with 102 nurses working in intensive care units in the West Black Sea Region of Turkey. Data were collected between February and May 2014 using a personal information form, the Visual Analogue Scale for Fatigue (VAS-F), the Hospital Anxiety and Depression Scale and the Pittsburg Sleep Quality Index. The intensive care nurses in the study were found to be experiencing fatigue. Significant correlations were observed between scores on the VAS-F Fatigue and anxiety (p=0.01), depression (p=0.002), and sleep quality (pnurses' levels of fatigue. These results can be of benefit in taking measures which may be used to reduce fatigue in nurses, especially the fatigue related to work organization and social life.

    Sleep disruption and fatigue are ubiquitous among cancer patients and are sources of stress that may compromise treatment outcomes. Previously, we showed that a cognitive behavioral stress management (CBSM) intervention reduced anxiety and other stress-related processes in women undergoing primary treatment for breast cancer. This study examined secondary outcomes from a CBSM intervention trial for women with early-stage breast cancer to test if CBSM would improve sleep quality and fatigue among these patients at a single site in southern Florida. CBSM-related effects have already been demonstrated for indicators of psychosocial adaptation (e.g., general and cancer-related anxiety). Patients were randomized to CBSM (n= 120) or a 1-day psychoeducation control group (n= 120). The Pittsburgh Sleep Quality Index (PSQI) and Fatigue Symptom Inventory were completed prior to randomization and 6 and 12 months after the baseline assignment. In latent growth analyses, women in CBSM reported greater improvements in PSQI sleep quality scores than controls, although there were no significant differences between conditions on PSQI total scores. Women in CBSM also reported greater reductions in fatigue-related daytime interference than controls, though there were no significant differences in changes in fatigue intensity. Changes in sleep quality were associated with changes in fatigue. Future work may consider integrating sleep and fatigue content into stress management interventions for women with early-stage breast cancer.

    To describe differences in fatigue severity in a sample of adult Puerto Rican patients during and postcancer treatments. Hispanics, including Puerto Ricans, are an understudied population who are under-represented in clinical trials, especially in symptom research. Although symptom management is a clinical priority in oncology care, treatment-related differences in Puerto Rican cancer patients' report of fatigue severity have not been well described. A cross-sectional survey was conducted from data of self-report of 138 Puerto Rican patients during and postcancer treatments at two ambulatory facilities located in San Juan, Puerto Rico. Fatigue severity was assessed using the Fatigue subscale from the Functional Assessment of Cancer Therapy-Fatigue quality of life questionnaire Spanish version. Differences in fatigue severity across type of treatment (radiation therapy, chemotherapy, combined radiation chemotherapy and post-treatment) were evaluated using nonparametric (Kruskal-Wallis and Mann-Whitney test) statistical tests. The majority of the participants had prostate (33%) and breast (32%) cancers and were receiving radiation therapy (43%) or chemotherapy (28%). The Kruskal-Wallis test showed that there was a statistically significant difference in fatigue scores between the different four treatment conditions, χ 2 (3) = 39.1, p = .001 with patients on combined radiation chemotherapy or chemotherapy alone experiencing more severe fatigue. Findings from the current study suggest that type of treatment is a key component of the symptom burden of fatigue among the Puerto Rican oncology population. Specially, patients receiving combined therapy or chemotherapy alone were at increased risk for experiencing severe fatigue, compared to radiation therapy and post-treatment patients. With the worldwide increase in migration of Puerto Rican families, nurses need to recognise that type of treatment is a key component of the symptom burden of fatigue among the Puerto

    Breast cancer survivors (BCSs) have identified attentional fatigue, a decrease in the ability to focus, as a persistent daily challenge; however, little is known regarding its impact on work ability. The purpose of this study was to examine the relationship between attentional fatigue and perceived work ability in BCSs controlling for the known covariates of age, education, household income, and time posttreatment. A cross-sectional, descriptive design was used. Breast cancer survivors who were currently employed and at least 1 year post-adjuvant treatment participated. Breast cancer survivors completed the Attentional Function Index and Work Ability Index questionnaires. Descriptive statistics, linear regression, and Fisher exact test were used for analysis. Sixty-eight female BCSs, ranging from 29 to 68 years of age (mean, 52.1 [SD, 8.6]) and on average 4.97 (SD, 3.36) years posttreatment, participated. More than one-fourth of BCSs (26.5%) reported poor to moderate perceived work ability, indicating substantial concerns regarding work performance. Attentional fatigue was found to significantly predict perceived work ability (P work ability. Attentional fatigue is a prevalent symptom posttreatment that is negatively related to perceived work ability in BCSs. Nurses are in a prime position to assess and intervene to alleviate attentional fatigue to improve work ability. Findings suggest a need for individual, comprehensive survivorship care plans to effectively address symptoms that impact work ability and, ultimately, the quality of life of cancer survivors.

    Cancer-related fatigue is prevalent and disabling. When persistent and unexplained, it is termed post-cancer fatigue (PCF). Cognitive behavioral therapy (CBT) and graded exercise therapy (GET) may improve symptoms and functional outcomes. To evaluate the outcomes of a randomized controlled trial, which assigned patients with post-cancer fatigue to education, or 12 weeks of integrated cognitive-behavioral therapy (CBT) and graded exercise therapy (GET). Three months after treatment for breast or colon cancer, eligible patients had clinically significant fatigue, no comorbid medical or psychiatric conditions that explained the fatigue, and no evidence of recurrence. The CBT/GET arm included individually tailored consultations at approximately two weekly intervals. The education arm included a single visit with clinicians describing the principles of CBT/GET and a booklet. The primary outcome was clinically significant improvement in self-reported fatigue (Somatic and Psychological HEalth REport 0-12), designated a priori as greater than one SD of improvement in fatigue score. The secondary outcome was associated improvement in function (role limitation due to physical health problems-36-Item Short Form Health Survey 0-100) comparing baseline, end treatment (12 weeks), and follow-up (24 weeks). There were 46 patients enrolled, including 43 women (94%), with a mean age of 51 years. Fatigue severity improved in all subjects from a mean of 5.2 (±3.1) at baseline to 3.9 (±2.8) at 12 weeks, suggesting a natural history of improvement. Clinically significant improvement was observed in 7 of 22 subjects in the intervention group compared with 2 of 24 in the education group (P < 0.05, χ 2 ). These subjects also had improvement in functional status compared with nonresponders (P < 0.01, t-test). Combined CBT/GET improves fatigue and functional outcomes for a subset of patients with post-cancer fatigue. Further studies to improve the response rate and the magnitude of

    Full Text Available We investigated the hypothesis that patients developing high-grade erythema of the breast skin during radiation treatment could be more likely to present increased levels of proinflammatory cytokines which may lead, in turn, to associated fatigue. Forty women with early stage breast cancer who received adjuvant radiotherapy were enrolled from 2007 to 2010. Fatigue symptoms, erythema, and cytokine levels (IL-1β, IL-2, IL6, IL-8, TNF-α, and MCP-1 were registered at baseline, during treatment, and after radiotherapy completion. Seven (17.5% patients presented fatigue without associated depression/anxiety. Grade ≥2 erythema was observed in 5 of these 7 patients. IL-1β, IL-2, IL-6, and TNF-α were statistically increased 4 weeks after radiotherapy (P<0.05. After the Heckman two-step analysis, a statistically significant influence of skin erythema on proinflammatory markers increase (P = 0.00001 was recorded; in the second step, these blood markers showed a significant impact on fatigue (P = 0.026. A seeming increase of fatigue, erythema, and proinflammatory markers was observed between the fourth and the fifth week of treatment followed by a decrease after RT. There were no significant effects of hormone therapy, breast volume, and anemia on fatigue. Our study seems to suggest that fatigue is related to high-grade breast skin erythema during radiotherapy through the increase of cytokines levels.

    Full Text Available Women diagnosed with breast cancer often endorse psychosocial concerns prior to treatment, which may influence symptom experiences. Among these, low perceived social support relates to elevated fatigue. Those with low social support perceptions may also experience a greater sense of rejection. We sought to determine if social rejection concerns post-surgery predict fatigue interference 12 months later in women with non-metastatic breast cancer. Depressive symptoms and pain severity after completion of adjuvant therapy (six months post-surgery were examined as potential mediators. Women (N = 240 with non-metastatic breast cancer were recruited 2–10 weeks post-surgery. Multiple regression analyses examined relationships among variables adjusting for relevant covariates. Greater rejection concerns at study entry predicted greater fatigue interference 12 months later (p < 0.01. Pain severity after adjuvant therapy partially mediated the relationship between social rejection concerns and fatigue interference, with significant indirect (β = 0.06, 95% CI (0.009, 0.176 and direct effects (β = 0.18, SE = 0.07, t(146 = 2.78, p < 0.01, 95% CI (0.053, 0.311. Therefore, pain levels post-treatment may affect how concerns of social rejection relate to subsequent fatigue interference. Interventions targeting fears of social rejection and interpersonal skills early in treatment may reduce physical symptom burden during treatment and into survivorship.

    This pilot study evaluated the effectiveness of energy conservation training to help post-therapy cancer survivors manage their fatigue. Twelve post-therapy cancer survivors were randomly assigned to an energy conservation training or usual care control (6 in each group). Participants in the intervention group received 1 to 2 hours of individual, face-to-face energy conservation training from an occupational therapist followed by once-a-week telephone monitoring sessions in the subsequent three weeks. Participants in the control group received standard care from their oncologist. Analysis of pre- and post-training data from the Piper Fatigue Scale (PFS) revealed significant reduction only in the sensory subscale of the PFS (Z = 2.21; p = 0.027) for the intervention group; but no significant reduction in the four subscale or total scores of the PFS for the control group. Findings demonstrate partial support for the effectiveness of energy conservation training in helping post-therapy cancer survivors manage their fatigue. Energy conservation training seems to be a viable strategy for managing cancer-related fatigue, though its efficacy is modest. Incorporating specific energy restoration strategies such as relaxation and meditation for future research may help advance the growing body of knowledge in symptom management for post-therapy cancer survivors.

  18. Is there a cognitive signature for MS-related fatigue?

    The compensatory approach of fatigue argues that it is a state caused by task load. The neuropsychiatric approach argues that fatigue is a trait (like depression), unrelated to environmental challenges. We propose that fatigue is an internal state that can be measured behaviorally only by applying specific cognitive tasks. PubMed was searched for articles concerning the relation between fatigue and cognitive performance or brain atrophy or functional MRI, distinguishing between the following cognitive domains: learning/memory, cognitive speed/selective attention, language, visuospatial processing, working memory, alerting/vigilance. Only tasks assessing alerting/vigilance are strongly related to fatigue. Areas with brain atrophy in fatigue patients overlap with brain regions activated in healthy controls performing alerting/vigilance tasks. Fatigue is not a compensatory state, nor a psychogenic trait. It is a feeling with behavioral effects that seems to be caused by brain atrophy or a neurochemical dysfunction of the alerting/vigilance system. © The Author(s), 2014.

    Patients with head and neck cancer (HNC) receiving intensity-modulated radiation therapy (IMRT) have particularly high rates of fatigue, and pre- and post-radiotherapy fatigue are prognostic factors for pathologic tumor responses and poor survival. Although inflammation has been proposed as one of the potential mechanisms of fatigue in cancer patients, findings have not been consistent, and there is a dearth of longitudinal studies. Accordingly, we conducted a prospective study in 46 HNC patients pre- and one-month post-IMRT. Fatigue was measured by the Multidimensional Fatigue Inventory (MFI)-20 at both time points along with the assessment of peripheral blood inflammatory markers including interleukin (IL)-6, soluble tumor necrosis factor receptor 2, and C-reactive protein (CRP) and gene expression. Generalized estimating equations were used to examine the association between inflammatory markers and fatigue. Gene enrichment analysis using MetaCore software was performed using up-regulated genes that were significantly associated with IMRT and fatigue. Significant associations between fatigue and IL-6 as well as CRP, which were independent of time, were observed. In addition the change in fatigue from pre- to post-IMRT was positively associated with the change in IL-6 and CRP. Analysis of up-regulated gene transcripts as a function of IMRT and fatigue revealed overrepresentation of transcripts related to the defense response and nuclear factor kappa B. In conclusion, our findings support the hypotheses that inflammation is associated with fatigue over time in HNC patients. Future studies on how inflammation contributes to fatigue as well as strategies targeting inflammation to reduce fatigue are warranted. PMID:26515035

    Full Text Available Simona Carnio, Rosario Francesco Di Stefano, Silvia Novello Oncology Department, University of Turin, AOU San Luigi, Orbassano, Italy Abstract: Lung cancer (LC remains the most common cause of cancer death in several countries across the world. Fatigue is the most frequently reported symptom in LC patients throughout the entire course of disease, and all international guidelines recommend early screening for cancer-related fatigue (CRF and symptoms that can affect patients' quality of life. In patients with LC, fatigue belongs to the symptom cluster of pain, depression, and insomnia, which are commonly observed simultaneously, but are typically treated as separate although they may have common biological mechanisms. The treatment of CRF remains one of the difficult areas in the oncology field: scarce evidence supports pharmacological therapies, while some interesting data arising indicates alternative remedies and physical exercise seem to be one of the most effective approaches for CRF at any stage of LC.

    Chronic lymphocytic leukaemia (CLL) is the most prevalent adult leukaemia and is incurable. The course and treatment of CLL is unique and characterised by repeated cycles of treatment, stable disease and relapse. Utilising a Self-Regulatory Model framework, we examined the relationship between patients' illness perceptions and cancer-specific stress, depressive symptoms and fatigue. Our aim was to test illness perceptions as predictors of these outcomes when variance due to disease and treatment variables was controlled. Data were collected on 147 patients with relapsed/refractory CLL as they entered a phase II clinical trial of an investigational medication at a university affiliated, National Cancer Institute designated comprehensive cancer center. Cancer-specific stress, depressive symptoms and fatigue interference. . Hierarchical multiple regression was used. Consequences and emotional representation were related to all outcomes (ps stress (p fatigue interference (p stress, depressive symptoms and fatigue interference in relapsed/refractory CLL.

    Full Text Available Abstract Background Persistent fatigue is recognised as one of the most common, ongoing symptoms reported by patients following cancer treatment and may have profound effects on the quality of life. However, recent cross-sectional studies also highlight the close relationship between cancer related fatigue (CRF and diagnoses of depression or anxiety disorder. There is currently limited information about the relationships between these conditions over time. We sought to examine the longitudinal relationships between fatigue and mood disorder in women treated with adjuvant therapy for early stage breast cancer. Methods Women who had recently completed adjuvant therapy for Stage I or II breast cancer (n = 212 were sent a questionnaire with established case thresholds for clinically-significant fatigue and psychological disorder, as well as a questionnaire assessing disability. Potentially relevant variables linked to fatigue states, including age, treatment modality, menopausal status, and hematological indices were recorded. The illness outcomes were assessed over 48 months of follow-up. Results The 176 women who responded to the questionnaire (84% had a mean age of 55 (range 24–83 years and had completed adjuvant treatment on average 10 (range 4.7 – 16.3 months previously. Radiotherapy had been administered, either alone (50% of women or in combination with chemotherapy (36%. Responses from 87 women (48% indicated a significant fatigue state (termed here post-cancer fatigue; PCF, and from 59 women (33% responses indicated significant psychological distress. Thirty-four women (19% were cases of fatigue alone (i.e. unaccompanied by psychological disorder, whereas 52 (30% were cases of both disorders. Multivariate analysis did not reveal any association between demographic, clinical or laboratory variables, and caseness for PCF.

    To assess changes in subjective fatigue symptoms of adolescent girls over a 15-year period and investigate factors related to these symptoms. A total of 86 items on physical health (including subjective fatigue symptoms), dietary life, and daily living were investigated and five items on physical activity were measured for approximately 100 female first-year dietetic students at a junior college each October over the 15-year period from 1994 to 2008. A total of 1,547 students (mean age, 19.2 +/- 0.3 years) were studied. Subjects were first divided into two groups using the median subjective fatigue score as the cutoff point, and annual changes in the proportion of students in the high subjective fatigue group were investigated by simple regression analysis. In addition, relationships between the two subjective fatigue groups and each item were investigated. 1) The proportion of students with many subjective fatigue symptoms showed a significantly increasing trend over the 15-year period. 2) Investigation of relationships between subjective fatigue symptoms and each factor revealed significance for many items, including dietary habits, life satisfaction, amount of sleep, and desire for a positive body image. 3) In order to determine which of the items were most strongly related to subjective fatigue symptoms, multiple logistic regression analysis was performed for the 15-year period as well as three 5-year periods into which it was divided. The results showed that the dietary habits score (an indicator of dietary habits) and life satisfaction were related to subjective fatigue symptoms during all four periods. As for other items, relationships were observed for amount of sleep in three, diet and salt intake score in two, and liking for coffee/tea, juice drinks, and oily food, bedtime snack, desire for body image, self-assessment of body type, and health consciousness in one. These findings indicate that perspectives in education for promoting the health of

    Full Text Available ABSTRACT Objective: To evaluate the properties of the Identity-Consequence Fatigue Scale (ICFS in patients with lung cancer (LC, assessing the intensity of fatigue and associated factors. Methods: This was a cross-sectional study involving LC patients, treated at a teaching hospital in Brazil, who completed the ICFS. Patients with chronic heart disease (CHD and healthy controls, matched for age and gender, also completed the scale. Initially, a Brazilian Portuguese-language version of the ICFS was administered to 50 LC patients by two independent interviewers; to test for reproducibility, it was readministered to those same patients. At baseline, the LC patients were submitted to spirometry and the six-minute walk test, as well as completing the Epworth Sleepiness Scale (ESS, Hospital Anxiety and Depression Scale (HADS, Medical Outcomes Study 36-item Short-Form Health Survey (SF-36, and Fatigue Severity Scale (FSS. Inflammatory status was assessed by blood C-reactive protein (CRP levels. To validate the ICFS, we assessed the correlations of its scores with those variables. Results: The sample comprised 50 patients in each group (LC, CHD, and control. In the LC group, the intraclass correlation coefficients for intra-rater and inter-rater reliability regarding ICFS summary variables ranged from 0.94 to 0.76 and from 0.94 to 0.79, respectively. The ICFS presented excellent internal consistency, and Bland-Altman plots showed good test-retest reliability. The ICFS correlated significantly with FSS, HADS, and SF-36 scores, as well as with CRP levels. Mean ICFS scores in the LC group differed significantly from those in the CHD and control groups. Conclusions: The ICFS is a valid, reliable instrument for evaluating LC patients, in whom depression, quality of life, and CRP levels seem to be significantly associated with fatigue.

    Fatigue is a prevalent and burdensome symptom for patients with incurable cancer receiving cancer treatment with palliative intent and is associated with reduced quality of life. Psychosocial interventions seem promising for management of fatigue among cancer patients. To assess the effects of psychosocial interventions for fatigue in adult patients with incurable cancer receiving cancer treatment with palliative intent. We searched the following databases: CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, and seven clinical trial registries; we also searched the reference lists of articles. The date of our most recent search was 29 November 2016. We included randomised controlled trials that compared psychosocial interventions in adults aged 18 years or over undergoing cancer treatment with palliative intent for incurable cancer versus usual care or other controls. Psychosocial interventions were defined as various kinds of interventions provided to influence or change cognitions, emotions, behaviours, social interactions, or a combination of these. Psychosocial interventions of interest to this review had to involve at least two interactions between the patient and the care provider in which the care provider gave the patient personal feedback concerning changes sought by these interventions. We included trials that reported fatigue as an outcome of interest. We used standard methodological procedures expected by Cochrane. Two review authors independently considered trials for inclusion in the review, assessed risk of bias, and extracted data, including information on adverse events. We assessed the quality of evidence using GRADE (Grading of Recommendations Assessment, Development, and Evaluation) and created a 'Summary of findings' table. We identified 14 studies (16 reports) that met inclusion criteria for this review and involved 3077 randomised participants in total. Most of these studies included a mixed sample of participants; we obtained data for the subset of

    soleus is also important for normal locomotion, we further performed a fatigue trial in the soleus and found that the decrease in relative force was greater and more rapid in solei from C-26 mice compared to controls. These data demonstrate that severe cancer cachexia causes profound muscle weakness that is not entirely explained by the muscle atrophy. In addition, cancer cachexia decreases the fatigue resistance of the soleus muscle, a postural muscle typically resistant to fatigue. Thus, specifically targeting contractile dysfunction represents an additional means to counter muscle weakness in cancer cachexia, in addition to targeting the prevention of muscle atrophy.

    Purpose: Most patients with localized breast cancer (LBC) who take adjuvant chemotherapy (CT) complain of fatigue and a decrease in quality of life during or after radiotherapy (RT). The aim of this longitudinal study was to compare the impact of RT alone with that occurring after previous CT on quality of life. Methods and Materials: Fatigue (the main endpoint) and cognitive impairment were assessed in 161 CT-RT and 141 RT patients during RT and 1 year later. Fatigue was assessed with Functional Assessment of Cancer Therapy-General questionnaires, including breast and fatigue modules. Results: At baseline, 60% of the CT-RT patients expressed fatigue vs. 33% of the RT patients (p <0.001). Corresponding values at the end of RT were statistically similar (61% and 53%), and fatigue was still reported at 1 year by more than 40% of patients in both groups. Risk factors for long-term fatigue included depression (odds ratio [OR] = 6), which was less frequent in the RT group at baseline (16% vs. 28 %, respectively, p = 0.01) but reached a similar value at the end of RT (25% in both groups). Initial mild cognitive impairments were reported by RT (34 %) patients and CT-RT (24 %) patients and were persistent at 1 year for half of them. No biological disorders were associated with fatigue or cognitive impairment. Conclusions: Fatigue was the main symptom in LBC patients treated with RT, whether they received CT previously or not. The correlation of persistent fatigue with initial depressive status favors administering medical and psychological programs for LBC patients treated with CT and/or RT, to identify and manage this main quality-of-life-related symptom.

    Cancer-related fatigue (CRF) is a common and relevant symptom in patients with advanced cancer that significantly decreases their quality of life. The aim of this study was to evaluate the effect of a physiotherapy programme on CRF and other symptoms in patients diagnosed with advanced cancer. The study was designed as a randomized controlled trial. Sixty patients diagnosed with advanced cancer receiving palliative care were randomized into two groups: the treatment group (n = 30) and the control group (n = 30). The therapy took place three times a week for 2 weeks. The 30-min physiotherapy session included active exercises, myofascial release and proprioceptive neuromuscular facilitation (PNF) techniques. The control group did not exercise. The outcomes included Brief Fatigue Inventory (BFI), Edmonton Symptom Assessment Scale (ESAS) and satisfaction scores. The exercise programme caused a significant reduction in fatigue scores (BFI) in terms of severity of fatigue and its impact on daily functioning. In the control group, no significant changes in the BFI were observed. Moreover, the physiotherapy programme improved patients' general well-being and reduced the intensity of coexisting symptoms such as pain, drowsiness, lack of appetite and depression. The analysis of satisfaction scores showed that it was also positively evaluated by patients. The physiotherapy programme, which included active exercises, myofascial release and PNF techniques, had beneficial effects on CRF and other symptoms in patients with advanced cancer who received palliative care. The results of the study suggest that physiotherapy is a safe and effective method of CRF management.

    Symptom researchers have proposed a model of inflammatory cytokine activity and dysregulation in cancer to explain co-occurring symptoms including pain, fatigue, and sleep disturbance. We tested the hypothesis that psychological stress accentuates inflammation and that stress and inflammation contribute to one's experience of the pain, fatigue, and sleep disturbance symptom cluster (symptom cluster severity, symptom cluster distress) and its impact (symptom cluster interference with daily life, quality of life). We used baseline data from a symptom cluster management trial. Adult participants (N = 158) receiving chemotherapy for advanced cancer reported pain, fatigue, and sleep disturbance on enrollment. Before intervention, participants completed measures of demographics, perceived stress, symptom cluster severity, symptom cluster distress, symptom cluster interference with daily life, and quality of life and provided a blood sample for four inflammatory biomarkers (interleukin-1β, interleukin-6, tumor necrosis factor-α, and C-reactive protein). Stress was not directly related to any inflammatory biomarker. Stress and tumor necrosis factor-α were positively related to symptom cluster distress, although not symptom cluster severity. Tumor necrosis factor-α was indirectly related to symptom cluster interference with daily life, through its effect on symptom cluster distress. Stress was positively associated with symptom cluster interference with daily life and inversely with quality of life. Stress also had indirect effects on symptom cluster interference with daily life, through its effect on symptom cluster distress. The proposed inflammatory model of symptoms was partially supported. Investigators should test interventions that target stress as a contributing factor in co-occurring pain, fatigue, and sleep disturbance and explore other factors that may influence inflammatory biomarker levels within the context of an advanced cancer diagnosis and treatment

  20. Fatigue proofing: The role of protective behaviours in mediating fatigue-related risk in a defence aviation environment.

    2017-02-01

    In the military or emergency services, operational requirements and/or community expectations often preclude formal prescriptive working time arrangements as a practical means of reducing fatigue-related risk. In these environments, workers sometimes employ adaptive or protective behaviours informally to reduce the risk (i.e. likelihood or consequence) associated with a fatigue-related error. These informal behaviours enable employees to reduce risk while continuing to work while fatigued. In this study, we documented the use of informal protective behaviours in a group of defence aviation personnel including flight crews. Semi-structured interviews were conducted to determine whether and which protective behaviours were used to mitigate fatigue-related error. The 18 participants were from aviation-specific trades and included aircrew (pilots and air-crewman) and aviation maintenance personnel (aeronautical engineers and maintenance personnel). Participants identified 147 ways in which they and/or others act to reduce the likelihood or consequence of a fatigue-related error. These formed seven categories of fatigue-reduction strategies. The two most novel categories are discussed in this paper: task-related and behaviour-based strategies. Broadly speaking, these results indicate that fatigued military flight and maintenance crews use protective 'fatigue-proofing' behaviours to reduce the likelihood and/or consequence of fatigue-related error and were aware of the potential benefits. It is also important to note that these behaviours are not typically part of the formal safety management system. Rather, they have evolved spontaneously as part of the culture around protecting team performance under adverse operating conditions. When compared with previous similar studies, aviation personnel were more readily able to understand the idea of fatigue proofing than those from a fire-fighting background. These differences were thought to reflect different cultural

Semiparametric group-based mixture modeling was used to identify distinct trajectories of fatigue assessed......-fatigue group. Conclusions The results show that one-fifth of women with breast cancer experience continuously high fatigue up to 8 months after surgery and may have been more anxious and physically inactive. This knowledge is important in targeting interventions to women with fatigue throughout their treatment...

  2. Diurnal cortisol rhythms, fatigue and psychosocial factors in five-year survivors of ovarian cancer.

    Fatigue is a challenge in ovarian cancer survivorship and greatly impacts quality of life. In other cancer populations, fatigue has been associated with abnormal diurnal cortisol patterns. However, little is known about biological and behavioral factors in 5+-year ovarian cancer survivors and potential mechanisms underlying persistent fatigue have not been investigated in this population. Moreover, relationships between neuroendocrine and psychosocial factors in 5+-year ovarian cancer survivors have not been studied. We addressed these issues by examining relationships between diurnal cortisol rhythms, fatigue, life stress, and social support in 30 survivors of ovarian cancer who were assessed at least 5 years (mean=6.20years) following their primary diagnosis. Flatter diurnal cortisol slopes were associated with higher levels of fatigue, suggesting a role for HPA-axis dysregulation in sustained fatigue experienced by survivors. Moreover, greater cumulative lifetime stressor exposure (p=0.023) and stressor severity (p=0.004) were associated with flatter diurnal cortisol slopes, while higher social attachment (p=0.001) was associated with steeper diurnal cortisol slopes. These findings suggest that ovarian cancer survivors with greater lifetime stress exposure or lower social attachment may be at increased risk for circadian rhythm disruption, which in turn is associated with fatigue. Future research should examine relationships of clinical stage and inflammatory cytokines to cortisol rhythms and fatigue in long-term ovarian cancer survivors, as well as investigating the clinical significance of abnormal diurnal cortisol profiles in this population.

    It has been proposed that an inappropriately conditioned fatigue sensation could be one cause of chronic fatigue. Although classical conditioning of the fatigue sensation has been reported in rats, there have been no reports in humans. Our aim was to examine whether classical conditioning of the mental fatigue sensation can take place in humans and to clarify the neural mechanisms of fatigue sensation using magnetoencephalography (MEG). Ten and 9 healthy volunteers participated in a conditioning and a control experiment, respectively. In the conditioning experiment, we used metronome sounds as conditioned stimuli and two-back task trials as unconditioned stimuli to cause fatigue sensation. Participants underwent MEG measurement while listening to the metronome sounds for 6 min. Thereafter, fatigue-inducing mental task trials (two-back task trials), which are demanding working-memory task trials, were performed for 60 min; metronome sounds were started 30 min after the start of the task trials (conditioning session). The next day, neural activities while listening to the metronome for 6 min were measured. Levels of fatigue sensation were also assessed using a visual analogue scale. In the control experiment, participants listened to the metronome on the first and second days, but they did not perform conditioning session. MEG was not recorded in the control experiment. The level of fatigue sensation caused by listening to the metronome on the second day was significantly higher relative to that on the first day only when participants performed the conditioning session on the first day. Equivalent current dipoles (ECDs) in the insular cortex, with mean latencies of approximately 190 ms, were observed in six of eight participants after the conditioning session, although ECDs were not identified in any participant before the conditioning session. We demonstrated that the metronome sounds can cause mental fatigue sensation as a result of repeated pairings of the sounds

    Informal caregivers (ICs) are increasingly involved in the monitoring of symptoms during advanced cancer patients' treatment with palliative intent. A common but subjective symptom during this extended treatment phase is fatigue. This exploratory longitudinal study aimed to determine agreement between patients and ICs about patients' fatigue severity. In addition, predictors of agreement over time were studied. A sample of 107 patients with advanced cancer (life expectancy ≥ six months) and their ICs completed the subscale fatigue severity of the Checklist Individual Strength based on the patient's status at baseline and six months later. This eight-item subscale has a validated cutoff to determine the presence of clinically relevant levels of fatigue. ICs' own fatigue severity, strain, self-esteem, and relationship satisfaction were examined as predictors of agreement. A total of 107 dyads completed measures at baseline and 69 dyads six months later. At baseline, ICs' significantly overestimated patients' fatigue severity (P congruence about the presence or absence of severe fatigue. On a group level, congruence did not significantly change over time. On a dyad level, there was a tendency to either remain congruent or reach congruence. Next to baseline congruence, ICs' fatigue severity and strain predicted ICs' fatigue ratings (R(2) = 0.22). Most ICs accurately predict presence or absence of clinically relevant levels of patients' fatigue. ICs' own fatigue severity and strain should be taken into account as they influence agreement.

    Purpose: To assess the magnitude and predictors of patient-reported fatigue among breast cancer patients receiving radiation therapy (RT). Methods and Materials: Patients receiving breast RT completed a survey querying fatigue at each weekly on-treatment visit. Patient-reported fatigue severity and interference was assessed on an ordinal scale of 0 to 4, using a validated scoring system. Baseline anxiety and depression scores were also obtained. The kinetics of mean fatigue scores per week and the maximum fatigue scores over the course of the entire treatment were assessed, and clinical predictors were identified by univariate and multivariate regression. Results: The average fatigue severity and interference scores were 0.6 and 0.46. The average fatigue scores increased to an equivalent extent from week to week, with expected increases of 0.99 in fatigue severity and 0.85 in interference over 7 weeks. Patients treated with hypofractionated RT (HF-RT) versus conventionally fractionated RT (CF-RT) had significantly fewer maximum fatigue severity or interference scores that were >2 (ie, severe or very severe; 29% vs 10% for severity, and 26% vs 8% for interference, P<.01). Age ≤45 years, presence of psychiatric/pain-related comorbidities, and baseline sadness and anxiety severity were predictive of average and maximum fatigue scores (P<.05), but variables related to treatment intensity (eg, mastectomy vs lumpectomy, chemotherapy use, radiation target volumes) and other host factors (working, children, marital status, proximity to RT facility) were not. Conclusion: Patient-reported fatigue modestly increases over RT courses, with less maximum fatigue reported with HF-RT. Younger age and baseline sadness, anxiety, and psychiatric/pain-related comorbidities are powerful predictors of fatigue, whereas other factors, such as treatment intensity, are not. Future studies will investigate interventions for patients at high risk for fatigue.

    The aim of this study was to describe women's experience of SLE-related fatigue, how they express the feeling of fatigue, impact on life and strategies developed to manage fatigue in daily living. Seven, semi-structured focus group discussions with 33 women were audio-taped, transcribed verbatim and analysed according to qualitative content analysis. Perceptions of SLE-related fatigue were sorted into four themes. Nature of Fatigue, involved the sensation, occurrence and character. Aspects Affected by Fatigue described emotions that arose together with fatigue as well as aspects of work, family life, social contacts and leisure activities that were affected by fatigue. Striving Towards Power and Control concluded the array of ways used to manage daily life and were categorized into the mental struggle, structure, restrict and provide. Factors Influencing the Perception of Fatigue described understanding from their surroundings and pain as strongly influencing the experience and perception of fatigue. SLE-related fatigue was portrayed as an overwhelming phenomenon with an unpredictable character, resulting in the feeling that fatigue dominates and controls most situations in life. The choice of strategies was described as a balance with implications for how fatigue limited a person's life. Health care professionals are advised to take a more active role to empower people with SLE to find their own balance as a way to achieve a feeling of being in control.

    The current study determined the prevalence of severe fatigue in adolescent and young adult (AYA) cancer patients (aged 18-35 years at diagnosis) consulting a multidisciplinary AYA team in comparison with gender- and age-matched population-based controls. In addition, impact of severe fatigue on quality of life and correlates of fatigue severity were examined. AYAs with cancer (n = 83) completed questionnaires including the Checklist Individual Strength (CIS-fatigue), Quality of Life (QoL)-Cancer Survivor, Hospital Anxiety and Depression Scale (reflecting psychological distress), and the Cancer Worry Scale (reflecting fear of cancer recurrence or progression). The vast majority of participants had been treated with chemotherapy (87%) and had no active treatment at the time of participation (73.5%). Prevalence of severe fatigue (CIS-fatigue score ≥35) in AYAs with cancer (48%, n = 40/83) was significantly higher in comparison with matched population-based controls (20%, n = 49/249; p fatigued AYAs with cancer reported lower QoL compared to non-severely fatigued AYAs with cancer (p fatigue severity (p fatigue based on a validated cut-off score was highly prevalent in this group of AYAs with cancer. QoL is significantly affected by severe fatigue, stressing the importance of detection and management of this symptom in those patients affected by a life-changing diagnosis of cancer in late adolescence or young adulthood.

    With improvements in both early detection and treatments for breast cancer, the number of survivors has increased dramatically in recent decades. One of the most common lingering symptoms posttreatment for cancer survivors is chronic fatigue. Based on family stress theory and Rolland's typology of illness, this qualitative study extends our understanding of the impact of persistent posttreatment fatigue on families and how breast cancer survivors manage the family issues that arise because of this chronic stressor. Participants included 35 female survivors of breast cancer (mean age = 54 years) who experienced fatigue after the completion of active cancer treatment, with the exception of long-term hormonal therapy. Data were generated from (a) observations of group sessions from a randomized controlled fatigue intervention designed to reduce fatigue in breast cancer survivors, (b) individual in-depth interviews, and (c) family sessions. Qualitative analysis revealed two broad themes that illustrate how the survivors manage the impact of fatigue on their families: Interpreting the meaning of the fatigue and Dealing with the inability to perform family roles. Study findings describe the difficulties in family adaptation when the family is not able to assign a clear meaning to a chronic symptom posttreatment and build upon family stress theory by highlighting interrelationships among communication patterns and role shifts in the family system. ©2011 APA

    Despite numerous proposed mechanisms, no definitive pathophysiology underlying radiotherapy-induced fatigue (RIF) has been established. However, the dysregulation of a set of 35 genes was recently validated to predict development of fatigue in prostate cancer patients receiving radiotherapy. To hypothesize novel pathways, and provide genetic targets for currently proposed pathways implicated in RIF development through analysis of the previously validated gene set. The gene set was analyzed for all phenotypic attributions implicated in the phenotype of fatigue. Initially, a "directed" approach was used by querying specific fatigue-related sub-phenotypes against all known phenotypic attributions of the gene set. Then, an "undirected" approach, reviewing the entirety of the literature referencing the 35 genes, was used to increase analysis sensitivity. The dysregulated genes attribute to neural, immunological, mitochondrial, muscular, and metabolic pathways. In addition, certain genes suggest phenotypes not previously emphasized in the context of RIF, such as ionizing radiation sensitivity, DNA damage, and altered DNA repair frequency. Several genes also associated with prostate cancer depression, possibly emphasizing variable radiosensitivity by RIF-prone patients, which may have palliative care implications. Despite the relevant findings, many of the 35 RIF-predictive genes are poorly characterized, warranting their investigation. The implications of herein presented RIF pathways are purely theoretical until specific end-point driven experiments are conducted in more congruent contexts. Nevertheless, the presented attributions are informative, directing future investigation to definitively elucidate RIF's pathoetiology. This study demonstrates an arguably comprehensive method of approaching known differential expression underlying a complex phenotype, to correlate feasible pathophysiology.

    To investigate the current status and characteristics of work-related fatigue among scientific and technical personnel and its associated factors, and to provide a scientific basis for further interventions. A cross-sectional survey was conducted in the staff from a single scientific institution, using a self-administered questionnaire. Basic information of participants, Fatigue Scale-14, and Job Content Questionnaire were collected. The prevalence of work-related fatigue among the scientific and technical personnel was 54.6%; work-related fatigue was positively correlated with occupational stress (rs = 0.384, P work-related fatigue included occupational stress profiles, social support, and educational status. A higher risk of work-related fatigue was found in the staff under high stress, compared with those under low stress (OR = 8.5, 95%CI = 3.9∼18.7). Social support served as a protective factor for work-related fatigue, while a higher level of education was correlated with more severe work-related fatigue. Work-related fatigue is common and serious among scientific and technical personnel, especially in those under high stress. Effective interventions according to occupational stress are of great importance to reduce work-related fatigue.

    Cancer-related fatigue (CRF) is common in women with breast cancer, but little is known of its relationship with perceived stress. We conducted a cross-sectional study to explore the associations of CRF with perceived stress, anxiety, depression, pain and sleep quality in 133 Chinese women (aged 25-68 years) with early stage breast cancer. The majority of women had completed surgery and chemotherapy and were awaiting radiotherapy. Self-administered questionnaires consisting of the Brief Fatigue Inventory, Perceived Stress Scale-10, Hospital Anxiety and Depression Scale, Brief Pain Inventory, and Pittsburgh Sleep Quality Index were used to collect data. Forty-five per cent of the women were severely fatigued. Compared with local healthy women and US breast cancer patients, the group's mean perceived stress score was significantly higher (both p stress (β = 0.18, p = 0.032), higher anxiety (β = 0.30, p stress was partially mediated by anxiety, suggesting a possible pathway from cancer and cancer treatment to CRF via stress appraisals and emotional distress.

    Full Text Available ABSTRACT Objective: to investigate health professionals' knowledge about the concept, assessment and intervention in fatigue in children and adolescents with cancer. Method: exploratory study with qualitative approach, with 53 health professionals (10 nurses, 33 assistant nurses, 3 physicians, 3 nutritionists, 2 psychologists and 2 physical therapists. Semi structured interviews were held, which were recorded and analyzed by means of inductive thematic content analysis. Results: the data were organized around three themes: knowledge of health professionals about fatigue; identification of fatigue and interventions to relieve fatigue. Conclusion: the results indicate the health professionals' limited knowledge about fatigue, as well as the lack of investment in their training and continuing education. Most of all, the lack of research on the theme in the Brazilian context remains a barrier to support improvements in care for this symptom in children and adolescents with cancer.

    Despite major advances in pain management, cancer pain is managed poorly in 80% of the patients with cancer. Due to deleterious side effects of pharmacology therapy in these people, there is an urgent need for clinical trials of non-pharmacological interventions. To examine the effect of therapeutic touch (TT) on the pain and fatigue of the cancer patients undergoing chemotherapy, a randomized and three-groups experimental study—experimental (TT), placebo (placebo TT), and control (usual care)—was carried out. Ninety patients undergoing chemotherapy, exhibiting pain and fatigue of cancer, were randomized into one of the three groups in the Cancer Center of Imam Khomeini Hospital in Tehran, Iran. Pain and fatigue were measured and recorded by participants before and after the intervention for 5 days (once a day). The intervention consisted of 30 min TT given once a day for 5 days between 10:00 a.m. and 10:30 a.m. The Visual Analogue Scale (VAS) of pain and the Rhoten Fatigue Scale (RFS) were completed for 5 days before and after the intervention by the subjects. The TT (significant) was more effective in decreasing pain and fatigue of the cancer patients undergoing chemotherapy than the usual care group, while the placebo group indicated a decreasing trend in pain and fatigue scores compared with the usual care group.

    Fatigue is common among cancer survivors, but fatigue in thyroid cancer (TC) survivors may be under-appreciated. This study investigated the severity and prevalence of moderate and severe fatigue in TC survivors. Potential predictive factors, including physical activity, were explored. A cross-sectional, written, self-administered TC patient survey and retrospective chart review were performed in an outpatient academic Endocrinology clinic in Toronto, Canada. The primary outcome measure was the global fatigue score measured by the Brief Fatigue Inventory (BFI). Physical activity was evaluated using the International Physical Activity Questionnaire-7 day (IPAQ-7). Predictors of BFI global fatigue score were explored in univariate analyses and a multivariable linear regression model. The response rate was 63.1% (205/325). Three-quarters of the respondents were women (152/205). The mean age was 52.5 years, and the mean time since first TC surgery was 6.8 years. The mean global BFI score was 3.5 (standard deviation 2.4) out of 10 (10 is worst). The prevalence of moderate-severe fatigue (global BFI score 4.1-10 out of 10) was 41.4% (84/203). Individuals who were unemployed or unable to work due to disability reported significantly higher levels of fatigue compared to the rest of the study population, in uni-and multivariable analyses. Furthermore, increased physical activity was associated with reduced fatigue in uni- and multivariable analyses. Other socio-demographic, disease, or biochemical variables were not significantly associated with fatigue in the multivariable model. Moderate or severe fatigue was reported in about 4/10 TC survivors. Independent predictors of worse fatigue included unemployment and reduced physical activity.

    To evaluate the properties of the Identity-Consequence Fatigue Scale (ICFS) in patients with lung cancer (LC), assessing the intensity of fatigue and associated factors. This was a cross-sectional study involving LC patients, treated at a teaching hospital in Brazil, who completed the ICFS. Patients with chronic heart disease (CHD) and healthy controls, matched for age and gender, also completed the scale. Initially, a Brazilian Portuguese-language version of the ICFS was administered to 50 LC patients by two independent interviewers; to test for reproducibility, it was readministered to those same patients. At baseline, the LC patients were submitted to spirometry and the six-minute walk test, as well as completing the Epworth Sleepiness Scale (ESS), Hospital Anxiety and Depression Scale (HADS), Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), and Fatigue Severity Scale (FSS). Inflammatory status was assessed by blood C-reactive protein (CRP) levels. To validate the ICFS, we assessed the correlations of its scores with those variables. The sample comprised 50 patients in each group (LC, CHD, and control). In the LC group, the intraclass correlation coefficients for intra-rater and inter-rater reliability regarding ICFS summary variables ranged from 0.94 to 0.76 and from 0.94 to 0.79, respectively. The ICFS presented excellent internal consistency, and Bland-Altman plots showed good test-retest reliability. The ICFS correlated significantly with FSS, HADS, and SF-36 scores, as well as with CRP levels. Mean ICFS scores in the LC group differed significantly from those in the CHD and control groups. The ICFS is a valid, reliable instrument for evaluating LC patients, in whom depression, quality of life, and CRP levels seem to be significantly associated with fatigue.

    Work-related fatigue is common among automobile factory employees. The purpose of this study was to assess fatigue of employees at a Chinese automobile factory. 238 employees (119 engineers and 119 workers) participated in this study. The following questionnaires were completed: demographic survey questionnaire, working condition questionnaire (WCQ), functional assessment of chronic illness therapy-fatigue (FACIT-F), subscales of multidimensional fatigue inventory (MFI), and Pittsburgh sleep quality index (PSQI). Both engineers and workers experienced fatigue. The workers (35.6 years old, SD = 6.7) generally felt more fatigue than engineers (42.6 years old, SD = 6.4). The engineers claimed to be more satisfied with the working conditions than workers. The WCQ showed good properties for assessing work-related factors, which were significantly correlated with fatigue (r = 0.568 for engineers and r = 0.639 for workers). For engineers, general fatigue was observed regularly and frequently, and for workers, physical fatigue usually had a long duration. The fatigue was significantly correlated with work-related factors, especially working environment and monotony. For workers, the duration of the work day also affected their fatigue. Some improvements to the working condition in this automobile factory should be considered.

    Jets in cross flow are of fundamental industrial importance and play an important role in validating turbulence models. Two jet configurations related to thermal fatigue phenomena are investigated: • T-junction of circular tubes where a heated jet discharges into a cold main flow and • Rectangular jet marked by a scalar discharging into a main flow in a rectangular channel. The T-junction configuration is a classical test case for thermal fatigue phenomena. The Vattenfall T-junction experiment was already subject of an OECD/NEA benchmark. A LES modelling and calculation strategy is developed and validated on this data. The rectangular-jet configuration is important for basic physical understanding and modelling and has been analyzed experimentally at CEA. The experimental work was focused on turbulent mixing between a slightly heated rectangular jet which is injected perpendicularly into the cold main flow of a rectangular channel. These experiments are analyzed for the first time with LES. The overall results show a good agreement between the experimental data and the CFD calculation. Mean values of velocity and temperature are well captured by both RANS calculation and LES. The range of critical frequencies and their amplitudes, however, are only captured by LES.

    MRI studies have shown gray-matter abnormalities in fatigued multiple sclerosis (MS) patients. However, given that physical disability is highly correlated to MS fatigue, it is often difficult to disentangle its effect in these MRI findings. The objective of this research paper is to investigate gray-matter damage in mildly disabled MS patients, addressing which variables were better related to fatigue while controlling for physical disability and depression. Forty-nine relapsing-remitting MS (RRMS) patients and 30 controls underwent MRI (3T). Fatigue was assessed using the Fatigue Severity Scale (FSS). Multivariate logistic regression was performed to assess the contribution of clinical and MRI metrics to fatigue. Statistical analyses were performed controlling for disability and depression. Fatigue was present in 22 (44.9%) patients. FSS score was highly correlated with EDSS (p = 0.00001). Patients with fatigue had lower brain cortical and subcortical gray-matter volumes. However, after controlling for EDSS, only the caudate and the accumbens volumes remained statistically significant. Fatigued MS patients have a global cortical and subcortical gray-matter atrophy that seems largely related to higher physical disability. However, striatal structures involved in effort-reward functions exhibited smaller volumes in fatigued patients, independently of physical disability and depressive symptoms, supporting the theory of cortico-striatal network impairment in MS fatigue. © The Author(s), 2015.

    Fatigue is the most common toxicity of all grade toxicities with regorafenib, was the second most common toxicity in the CORRECT (regorafenib monotherapy for previously treated metastatic colorectal cancer) study, and is a major reason for early dose modification. The results from a recent randomized study suggested that dexamethasone (DEX) can improve cancer-related fatigue. We retrospectively analyzed the effect of prophylactic use of an oral DEX on fatigue during regorafenib treatment in patients with metastatic colorectal cancer (mCRC). A total of 105 patients who had received regorafenib at our institution from May 2013 to August 2014 were divided into 2 groups according to oral DEX use (2 mg/day; at the physician's discretion). Of the 105 patients, 31 received prophylactic DEX and 74 received regorafenib alone. The time to dose modification was significantly longer in the DEX group than in the no DEX group (15 days vs. 9 days; P = .009). The incidence of fatigue (grade ≥ 1) was significantly lower with DEX than without DEX (25.8% vs. 50.0%; P = .022). Fewer patients experienced a decreased appetite (grade ≥ 1; 3.2% vs. 35.1%; P regorafenib treatment, resulting in prolonging the time to dose modification for regorafenib. The decreased incidence of appetite loss and HFSR also suggest that concurrent DEX administration with regorafenib warrants further investigation. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim of this study was to explore the mechanism on perceived exertion during muscle fatigue. A total of 15 individuals in the fatigue group and 13 individuals in the nonfatigue group were recruited into this study, performing 200 intermittent handgrip contractions with 30% maximal voluntary contraction. The force, surface electromyography (sEMG), movement-related cortical potentials (MRCPs), and rating perception of effort (RPE) were combined to evaluate the perceived exertion during muscle fatigue. The maximal handgrip force significantly decreased (Pfatigue. The RPE scores reported by the individuals and the motor potential amplitude of MRCPs in the fatigue group significantly increased (Pfatigue but could also reflect the peripheral local muscle fatigue.

    To investigate the influence of music therapy on the reduction of fatigue in women with breast or gynecological malignant neoplasia during radiotherapy, since it is one of the most frequent side effects of this type of treatment, and may interfere with self-esteem, social activities, and quality of life. Randomized controlled trial (control group [CG] and music therapy group [MTG]) to assess fatigue, quality of life, and symptoms of depression in women undergoing radiotherapy using the Functional Assessment of Cancer Therapy: Fatigue (FACT-F) version 4, Functional Assessment of Cancer Therapy-General (FACT-G) version 4, and Beck Depression Inventory in 3 separate times, namely, during the first week of radiotherapy, on the week of the intermediary phase, and during the last week of radiotherapy. Individual 30- to 40-minute sessions of music therapy with the presence of a trained music therapist were offered to participants. In this study, 164 women were randomized and 116 (63 CG and 53 MTG) were included in the analyses, with mean age of 52.90 years (CG) and 51.85 years (MTG). Participants in the MTG had an average of 10 music therapy sessions, totaling 509 sessions throughout the study. FACT-F results were significant regarding Trial Outcome Index ( P = .011), FACT-G ( P = .005), and FACT-F ( P = .001) for the MTG compared with the CG. Individual music therapy sessions may be effective to reduce fatigue related to cancer and symptoms of depression, as well as to improve quality of life for women with breast or gynecological cancer undergoing radiotherapy. Further well-designed research studies are needed to adequately determine the effects of music therapy on fatigue.

    Full Text Available Objective. To investigate the pathophysiological role of pro- and anti-inflammatory cytokines in primary multiple sclerosis-related fatigue. Methods. Fatigued and non-fatigued patients with multiple sclerosis (MS were recruited and their cytokine profiles compared. Patients with secondary fatigue were excluded. Fatigue was assessed with the self-reported Checklist Individual Strength (CIS20r, subscale fatigue. A CIS20r fatigue cut-off score of 35 was applied to differentiate between non-fatigued (CIS20r fatigue ≤34 and fatigued (CIS20r fatigue ≥35 patients with MS. Blood was collected to determine the serum concentrations of pro-inflammatory cytokines (IL-1β, IL-2, IL-6, IL-8, IL-12p70, IL-17, TNFα, and IFN-γ and anti-inflammatory cytokines (IL-4, IL-5, IL-10, and IL-13. We controlled for the confounding effect of age, gender, duration of MS, disease severity, type of MS, and use of immunomodulatory drugs. Results. Similar cytokine levels were observed between MS patients with (n=21 and without fatigue (n=14. Adjusted multiple regression analyses showed a single significant positive relationship, that of IL-6 with CIS20r fatigue score. The explained variance of the IL-6 model was 21.1%, once adjusted for the confounding effect of age. Conclusion. The pro-inflammatory cytokine interleukin-6 (IL-6 may play a role in the pathophysiology of primary fatigue in patients with MS. Trial Registrations.

    Background and Objectives Prolonged fatigue is common among employees, but the relationship between prolonged fatigue and job-related psychosocial factors is seldom studied. This study aimed (1) to assess the individual relations of physical condition, psychological condition, and job-related psychosocial factors to prolonged fatigue among employees, and (2) to clarify the associations between job-related psychosocial factors and prolonged fatigue using hierarchical regression when demographic characteristics, physical condition, and psychological condition were controlled. Methods A cross-sectional study was employed. A questionnaire was used to obtain information pertaining to demographic characteristics, physical condition (perceived physical health and exercise routine), psychological condition (perceived mental health and psychological distress), job-related psychosocial factors (job demand, job control, and workplace social support), and prolonged fatigue. Results A total of 3,109 employees were recruited. Using multiple regression with controlled demographic characteristics, psychological condition explained 52.0% of the variance in prolonged fatigue. Physical condition and job-related psychosocial factors had an adjusted R2 of 0.370 and 0.251, respectively. Hierarchical multiple regression revealed that, among job-related psychosocial factors, job demand and job control showed significant associations with fatigue. Conclusion Our findings highlight the role of job demand and job control, in addition to the role of perceived physical health, perceived mental health, and psychological distress, in workers’ prolonged fatigue. However, more research is required to verify the causation among all the variables. PMID:26930064

    In the course of a cancer trajectory, many patients suffer from distressing fatigue. In past years, research has shown that care givers tend to underestimate or even to ignore this frequent phenomenon. Despite increasing knowledge, fatigue seems to remain an orphan topic in symptom management. A qualitative research strategy was used to explore the perception of cancer patients regarding the awareness of fatigue in professionals and the way they deal with it. Patients also evaluated the usefulness of some currently available information material about fatigue. The expert-opinion of cancer patients in Switzerland and England was analysed. Convenient sampling guided the selection process of seven patients in each country. A tape-recorded focus-group interview served as method to collect and transcribe data. Data were analysed according to the framework analyses by Richie & Spencer. Results were very similar in both countries. Patients stated a great need for more information regarding fatigue. They feel that care givers are not sufficiently aware of it and that a specific support is not part of current standard practice. The information material was well received and generally judged as very good and helpful. Communication barriers in professionals as well as in patients continue to exist. Patients wish to be better informed by care givers. The available information material serves well to support this information as they provide words for the unmentioned phenomenon. Far more professional fatigue education is needed to raise care givers' awareness.

    To assess which laboratory and clinical factors are associated with fatigue in patients with terminal cancer. We evaluated 51 patients with advanced incurable solid tumors using the Chalder Fatigue Questionnaire (CFQ) and the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale for fatigue; the Pittsburgh Sleep Quality Index (PSQI-BR) for sleep quality; the Hospital Anxiety and Depression Scale (HADS) for anxiety and depression; the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire, Version 3.0 (QLQ C-30); and Functional Assessment of Cancer Therapy (FACT) for quality of life. We also analyzed several inflammatory markers and the modified Glasgow prognostic score (mGPS). We observed severe fatigue in 19 (38%) patients (FACIT-F score >36). There was a significant correlation between fatigue as evaluated by the CFQ and quality of sleep and between the CFQ mental fatigue subscale scores and TNF-α level. When fatigue was evaluated using the FACIT-F scale, we observed a significant association between fatigue and anxiety/depression, quality of sleep, mGPS, and hemoglobin levels. Fatigue measured both with the CFQ and FACIT-F scale correlated with poor quality of life according to the EORTC QLQ C-30. In patients with advanced cancer, fatigue is a common symptom associated with the presence of inflammation, poor quality of sleep, depression/anxiety, and poor quality of life. © The Author(s) 2015.

    Cognitive behaviour therapy (CBT) can significantly reduce fatigue in chronic fatigue syndrome (CFS), but little is known about the process of change taking place during CBT. Based on a recent treatment model (Wiborg et al. J Psych Res 2012), we examined how (changes in) cognitions and behaviour are related to the decrease in fatigue. We included 183 patients meeting the US Centers for Disease Control criteria for CFS, aged 18 to 65 years, starting CBT. We measured fatigue and possible process variables before treatment; after 6, 12 and 18 weeks; and after treatment. Possible process variables were sense of control over fatigue, focusing on symptoms, self-reported physical functioning, perceived physical activity and objective (actigraphic) physical activity. We built multiple regression models, explaining levels of fatigue during therapy by (changes in) proposed process variables. We observed large individual variation in the patterns of change in fatigue and process variables during CBT for CFS. Increases in the sense of control over fatigue, perceived activity and self-reported physical functioning, and decreases in focusing on symptoms explained 20 to 46% of the variance in fatigue. An increase in objective activity was not a process variable. A change in cognitive factors seems to be related to the decrease in fatigue during CBT for CFS. The pattern of change varies considerably between patients, but changes in process variables and fatigue occur mostly in the same period. © 2013.

    To develop a Chinese version of the human immunodeficiency virus-related Fatigue Scale and examine its reliability and validity. Fatigue is found in more than 70% of people infected with human immunodeficiency virus. However, a scale to assess fatigue in human immunodeficiency virus-positive people has not yet been developed for use in Chinese-speaking countries. A methodologic study involving instrument development and psychometric evaluation was used. The human immunodeficiency virus-related Fatigue Scale was examined through a two-step procedure: (1) translation and back translation and (2) psychometric analysis. A sample of 142 human immunodeficiency virus-positive patients was recruited from the Infectious Disease Outpatient Clinic in central Taiwan. Their fatigue data were analysed with Cronbach's α for internal consistency. Two weeks later, the data of a random sample of 28 patients from the original 142 were analysed for test-retest reliability. The correlation between the World Health Organization Quality of Life Assessment-Human Immunodeficiency Virus and the Chinese version of the human immunodeficiency virus-related Fatigue Scale was analysed for concurrent validity. The Chinese version of the human immunodeficiency virus-related Fatigue Scale scores of human immunodeficiency virus-positive patients with highly active antiretroviral therapy and those without were compared to demonstrate construct validity. The internal consistency and test-retest reliability of the Chinese version of the human immunodeficiency virus-related Fatigue Scale were 0·97 and 0·686, respectively. In regard to concurrent validity, a negative correlation was found between the scores of the Chinese version of the human immunodeficiency virus-related Fatigue Scale and the World Health Organization Quality of Life Assessment-Human Immunodeficiency Virus. Additionally, the Chinese version of the human immunodeficiency virus-related Fatigue Scale could be used to effectively

    The relationships among napping and sleep quality, fatigue, and quality of life (QOL) in cancer patients are not clearly understood. The aim of the study was to determine whether daytime napping is associated with nighttime sleep, fatigue, and QOL in cancer patients. In total, 187 cancer patients were recruited. Daytime napping, nighttime self-reported sleep, fatigue, and QOL were assessed using a questionnaire. Objective sleep parameters were collected using a wrist actigraph. According to waking-after-sleep-onset measurements, patients who napped during the day experienced poorer nighttime sleep than did patients who did not (t = -2.44, P = .02). Daytime napping duration was significantly negatively correlated with QOL. Patients who napped after 4 PM had poorer sleep quality (t = -1.93, P = .05) and a poorer Short-Form Health Survey mental component score (t = 2.06, P = .04) than did patients who did not. Fatigue, daytime napping duration, and sleep quality were significant predictors of the mental component score and physical component score, accounting for 45.7% and 39.3% of the variance, respectively. Daytime napping duration was negatively associated with QOL. Napping should be avoided after 4 PM. Daytime napping affects the QOL of cancer patients. Future research can determine the role of napping in the sleep hygiene of cancer patients.

    The Pictorial Representation of Self and Illness Measure (PRISM) measures in a simple, graphic way the burden of suffering due to illness. The question addressed in this study is whether the PRISM is a valid instrument to measure suffering in cancer survivors experiencing severe fatigue. Quantitative and qualitative data of a previous randomized controlled trial demonstrating the efficacy of cognitive behavior therapy (CBT) especially designed for postcancer fatigue was used to assess convergent validity and sensitivity to change in a sample of 83 cancer survivors. The PRISM, yielding self-illness separation (SIS-fatigue = suffering due to fatigue; SIS-cancer = suffering due to cancer), fatigue severity (Checklist Individual Strength; CIS-fatigue), functional impairment, psychological well-being, quality of life, and coping with the experience of cancer (Impact of Event Scale; IES). Moderate significant correlations were found with the PRISM and the above-mentioned measures. On the basis of SIS scores, the sample was divided into two separate groups: cancer survivors who suffered more because of fatigue and cancer survivors who suffered more because they had cancer in the past. The two groups had different scores on CIS-fatigue and IES, in line with that aspect that caused them the most suffering. The qualitative data confirmed this finding. Participants in the CBT condition demonstrated a significant difference between SIS-fatigue at baseline versus 6 months later compared with those in the waiting list condition. No change of SIS-cancer was found. The PRISM seems to be a valuable tool in fatigue research and clinical practice. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    Purpose: The purpose of this study was to evaluate the efficacy of art therapy to control fatigue in cancer patients during course of radiotherapy and its impact on quality of life (QoL). Materials and Methods: Fifty cancer patients receiving radiotherapy received weekly art therapy sessions using famous painting appreciation. Fatigue and QoL were assessed using the Brief Fatigue Inventory (BFI) Scale and the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) at baseline before starting radiotherapy, every week for 4 weeks during radiotherapy, and at the end of radiotherapy. Mean changes of scores over time were analyzed using a generalized linear mixed model. Results: Of the 50 patients, 34 (68%) participated in 4 sessions of art therapy. Generalized linear mixed models testing for the effect of time on mean score changes showed no significant changes in scores from baseline for the BFI and FACIT-F. The mean BFI score and FACIT-F total score changed from 3.1 to 2.7 and from 110.7 to 109.2, respectively. Art therapy based on the appreciation of famous paintings led to increases in self-esteem by increasing self-realization and forming social relationships. Conclusion: Fatigue and QoL in cancer patients with art therapy do not deteriorate during a period of radiotherapy. Despite the single-arm small number of participants and pilot design, this study provides a strong initial demonstration that art therapy of appreciation for famous painting is worthy of further study for fatigue and QoL improvement. Further, it can play an important role in routine practice in cancer patients during radiotherapy. PMID:27306778

    Objectives: The origin of fatigue, a common symptom in cancer patients undergoing radiotherapy(RT), remains unresolved. The objectives of this study were to evaluate subjective fatigue in patients with localized prostate cancer utilizing validated instruments and to examine the relationship of fatigue with radiotherapy. Methods: Instruments used included: Piper Fatigue Scale (PFS), Beck Depression Inventory (BDI), Epworth Sleepiness Scale (ESS) and Functional Assessment of Cancer Therapy - Prostate (FACT-P). Patients are evaluated before radiation therapy (PRT), at 4 weeks' (RT4), at completion of RT (7-8 weeks, RTC) of radiotherapy, and at 4 weeks follow-up (RTF). Seventeen prostate cancer subjects with a mean age of 64.6 years (range 55-73) were assessed. Results: PRT median scores on BDI, PFS, ESS, FACT(G), and FACT (P) were 4.00, 2.41, 6.0, 94, and 130 respectively. No significant changes in these scores were noted at RT4, RTC and RTF. Significant negative relationship was noted between PFS and physical well being sub-scale of FACT (G) at PRT(r=-0.76), RTC(r=-0.58), and RTF(r=-0.86). On BDI, four subjects reported depressive symptoms PRT. Two of these four subjects also scored higher on PFS. However, no significant changes were noted on their BDI and PFS scores during the study. No other patients reported depressive symptoms during treatment. Conclusions: These findings indicate: (1) No significant change in the baseline scores of fatigue and psychological measures during radiotherapy. (2) Self reported fatigue is not common in our patient population. (3) A significant relationship exists between scores on PFS and Physical well being sub-scale of FACT (G). Relationship between PFS, FACT-P and psychological functioning, severity of disease and PSA levels will also be presented

    The purpose of this study was to identify the effects of foot reflexology on nausea, vomiting and fatigue in breast cancer patients undergoing chemotherapy. The research was a quasi-experimental study using a non-equivalent pre-post design and was conducted from Jan. 26, to Mar. 20, 2004. The subjects consisted of 34 patients with 18 in the experimental group and 16 in control group. A pretest and 2 posttests were conducted to measure nausea, vomiting and fatigue. For the experimental group, foot reflexology, which was consisted of 4 phases for 40 minutes, was given by a researcher and 4 research assistants. The collected data were analyzed by repeated measures ANOVA using the SPSS WIN 10.0 program. There was a statistically significant decrease in nausea, and vomiting in the experimental group compared to the control group over two different times. In addition, there was a statistically significant decrease in fatigue in the experimental group compared to the control group over two different times. Foot reflexology was effective on nausea, vomiting and fatigue in breast cancer patients receiving chemotherapy in this study. Therefore, foot reflexology can be usefully utilized as a nursing intervention in the field of cancer nursing for breast cancer patients receiving chemotherapy.

    The aim was to describe fatigue-related problems reported by post-cardiac arrest adults with chronic fatigue and energy conservation strategies generated using an Energy Conservation plus Problem Solving Therapy intervention. Following an introduction to the intervention process outlined in a Participant Workbook, participants engaged in the telephone intervention by identifying one to two fatigue-related problems. They then brainstormed with the interventionist to identify potential strategies to reduce fatigue, tested them, and either modified the strategies or moved to the next problem over three to five sessions. Eighteen cardiac arrest survivors with chronic fatigue identified instrumental activities of daily living and leisure activities as fatigue-related activities more frequently than basic activities of daily living. Energy Conservation strategies used most frequently were: plan ahead, pace yourself, delegate to others, and simplify the task. Post-cardiac arrest adults living in the community with chronic fatigue can return to previous daily activities by using energy conservation strategies such as planning ahead, pacing tasks, delegating tasks, and simplifying tasks.

  9. Work-related fatigue and recovery: the contribution of age, domestic responsibilities and shiftwork.

    Winwood, Peter C; Winefield, Antony H; Lushington, Kurt

    2006-11-01

    This paper reports a study of the relationship between age, domestic responsibilities (being partnered and having dependents), recovery from shiftwork-related fatigue and the evolution of maladaptive health outcomes among full-time working female nurses. Several studies have suggested that full-time working women with family responsibilities are at greater risk of developing work-related fatigue problems than single women without these responsibilities. A questionnaire was distributed in 2004 to 2400 nurses at two hospitals in Australia, and 1280 responses were obtained (response rate 54%). The data from a purposive sample of 846 full-time working nurses are reported here. Domestic responsibilities were not related to differences in fatigue and recovery. Our results suggested that for full-time shiftworking nurses, being part of a family structure, may actually be protective against the development of maladaptive fatigue. The most important factor determining maladaptive fatigue outcome was shift pattern worked, particularly rotation including night duty. The effect of age was equivocal. The youngest age group reported the highest fatigue and poorest recovery compared to the oldest group, who reported the best characteristics. However, this latter group may represent a particularly well-adapted 'survivor cohort'. The relationship between age and fatigue was partly confounded by older, experienced, nurses with greater job responsibilities, working fewer multiple shifts including night duty. In general, increasing age was not associated with poorer recovery or higher maladaptive fatigue. Unpredictable internal shift rotations, including night duty, which are traditional and typical in nursing, are inimical to maintaining nurses' health. More creative approaches to rostering for nurses working multiple shifts are a necessary step towards reducing wastage from the profession due to chronic work-related fatigue. Younger nurses in particular, may need more support than

    Background It has been proposed that an inappropriately conditioned fatigue sensation could be one cause of chronic fatigue. Although classical conditioning of the fatigue sensation has been reported in rats, there have been no reports in humans. Our aim was to examine whether classical conditioning of the mental fatigue sensation can take place in humans and to clarify the neural mechanisms of fatigue sensation using magnetoencephalography (MEG).

    Cognitive behavioural therapy (CBT) effectively reduces fatigue directly following treatment in patients with Multiple Sclerosis (MS), but little is known about the process of change during and after CBT. Additional analysis of a randomized clinical trial. To investigate which psychological factors mediate change in fatigue during and after CBT. TREFAMS-CBT studied the effectiveness of a 16-week CBT treatment for MS-related fatigue. Ninety-one patients were randomized (44 to CBT, 47 to the MS-nurse consultations). Mediation during CBT treatment was studied using assessments at baseline, 8 and 16weeks. Mediation of the change in fatigue from post-treatment to follow-up was studied separately using assessments at 16, 26 and 52weeks. Proposed mediators were: changes in illness cognitions, general self-efficacy, coping styles, daytime sleepiness, concentration and physical activity, fear of disease progression, fatigue perceptions, depression and physical functioning. Mediators were separately analysed according to the product-of-coefficients approach. Confidence intervals were calculated with a bootstrap procedure. During treatment the decrease in fatigue brought on by CBT was mediated by improved fatigue perceptions, increased physical activity, less sleepiness, less helplessness, and improved physical functioning. Post-treatment increases in fatigue levels were mediated by reduced physical activity, reduced concentration, and increased sleepiness. These results suggests that focusing on improving fatigue perceptions, perceived physical activity, daytime sleepiness, helplessness, and physical functioning may further improve the effectiveness of CBT for fatigue in patients with MS. Maintenance of treatment effects may be obtained by focusing on improving physical activity, concentration and sleepiness. Copyright © 2018 Elsevier Inc. All rights reserved.

    Cancer-related fatigue (CRF) is the most stressful and prevalent symptom in paediatric oncology patients. This integrative review aimed to identify, analyse and synthesise the evidence of non-pharmacological intervention studies to manage fatigue and psychological stress in a paediatric population with cancer. Eight electronic databases were used for the search: PubMed, Web of Science, CINAHL, LILACS, EMBASE, SCOPUS, PsycINFO and the Cochrane Library. Initially, 273 articles were found; after the exclusion of repeated articles, reading of the titles, abstracts and the full articles, a final sample of nine articles was obtained. The articles were grouped into five categories: physical exercise, healing touch, music therapy, therapeutic massage, nursing interventions and health education. Among the nine studies, six showed statistical significance regarding the fatigue and/or stress levels, showing that the use of the interventions led to symptoms decrease. The most frequently tested intervention was programmed physical exercises. It is suggested that these interventions are complementary to conventional treatment and that their use can indicate an improvement in CRF and psychological stress. © 2015 John Wiley & Sons Ltd.

    A growing body of evidence suggests that exposure to environmental pollutions is related to health problems. It is, however, questionable whether this condition affects working performance in occupational settings. The aim of this study is to determine the predictive value of age as well as traffic related air and noise pollutions for fatigue. 246 traffic officers participated in this study. Air pollution data were obtained from the local Air Quality Control Company. A sound level meter was used for measuring ambient noise. Fatigue was evaluated by the MFI-20 questionnaire. The general and physical scales showed the highest, while the reduced activity scale showed the lowest level of fatigue. Age had an independent direct effect on reduced activity and physical fatigue. The average of daytime equivalent noise level was between 71.63 and 88.51 dB(A). In the case of high noise exposure, older officers feel more fatigue than younger ones. Exposure to PM10 and O3 resulted in general and physical fatigue. Complex Interactions between SO2, CO and NO2 were found. Exposure to noise and some components of air pollution, especially O3 and PM10, increases fatigue. The authorities should adopt and rigorously implement environmental protection policies in order to protect people.

    Clinical reports have shown that adjuvant chemotherapy has a negative impact on perceived cognitive impairment (PCI) of patients with breast cancer; however, evidence concerning the effects of psychological factors such as post-traumatic stress disorder (PTSD) symptoms on PCI is limited, especially in relation to Chinese patients with breast cancer. This research investigated the associations between psychological factors and PCI in Chinese women with breast cancer. In total, 204 women with breast cancer were assessed for PCI, PTSD symptoms, fatigue, anxiety, and depression using self-report measures. Hierarchical linear regression was conducted to investigate the associations between the variables of interest and PCI. Two hundred and two women were included in the final analysis; two of those originally tested were excluded because of missing data. A univariate analysis showed that PCI was significantly related to education, PTSD symptoms (re-experience, avoidance, and hyperarousal), fatigue, depression, anxiety, and undergoing chemotherapy or radiotherapy. Hierarchical linear regression revealed that PTSD symptoms and fatigue (ΔR(2)  = 0.26, P fatigue are important risk factors for significant PCI and are therefore worthy of further investigation.

    2007-01-01

    On the idea that fatigue damage is localized at the microscopic scale, a scale smaller than the mesoscopic one of the Representative Volume Element (RVE), a three-dimensional two scale damage model has been proposed for High Cycle Fatigue applications. It is extended here to aniso-thermal cases and then to thermo-mechanical fatigue. The modeling consists in the micro-mechanics analysis of a weak micro-inclusion subjected to plasticity and damage embedded in an elastic meso-element (the RVE of continuum mechanics). The consideration of plasticity coupled with damage equations at micro-scale, altogether with Eshelby-Kroner localization law, allows to compute the value of microscopic damage up to failure for any kind of loading, 1D or 3D, cyclic or random, isothermal or aniso-thermal, mechanical, thermal or thermo-mechanical. A robust numerical scheme is proposed in order to make the computations fast. A post-processor for damage and fatigue (DAMAGE-2005) has been developed. It applies to complex thermo-mechanical loadings. Examples of the representation by the two scale damage model of physical phenomena related to High Cycle Fatigue are given such as the mean stress effect, the non-linear accumulation of damage. Examples of thermal and thermo-mechanical fatigue as well as complex applications on real size testing structure subjected to thermo-mechanical fatigue are detailed. (authors)

    Radiation (RT) dose to the central nervous system (CNS) has been implicated as a contributor to treatment-related fatigue in head and neck cancer (HNC) patients undergoing radiation therapy (RT). This study evaluates the association of RT dose to CNS structures with patient-reported (PRO) fatigue scores in a population of HNC patients. At pre-RT (baseline), 6th week of RT, and 1-month post-RT time points, Multidimensional Fatigue Inventory (MFI-20) scores were prospectively obtained from 124 patients undergoing definitive treatment for HNC. Medulla, pons, midbrain, total brainstem, cerebellum, posterior fossa, and pituitary dosimetry were evaluated using summary statistics and dose-volume histograms, and associations with MFI-20 scores were analyzed. Maximum dose (Dmax) to the brainstem and medulla was significantly associated with MFI-20 scores at 6th week of RT and 1-month post-RT time points, after controlling for baseline scores (p<0.05). Each 1Gy increase in medulla Dmax resulted in an increase in total MFI-20 score over baseline of 0.30 (p=0.026), and 0.25 (p=0.037), at the 6th week of RT and 1-month post-RT, respectively. Each 1Gy increase in brainstem Dmax resulted in an increase in total MFI-20 score over baseline of 0.30 (p=0.027), and 0.25 (p=0.037) at the 6th week of RT, 1-month post-RT, respectively. Statistically significant associations were not found between dosimetry for the other CNS structures and MFI-20 scores. In this analysis of PRO fatigue scores from a population of patients undergoing definitive RT for HNC, maximum dose to the brainstem and medulla was associated with a significantly increased risk of acute patient fatigue.

    The aim of this study was to investigate the time course of recovery after an academic exam as a model of high workload and its association with stress-related fatigue. Thirty-six medical students (17 females, 19 males) filled out diaries during an exam phase, starting 2 days prior to the exam, and a control phase 4 weeks after the exam for 14 days, respectively. Fatigue, distress, quality of sleep, and health complaints were assessed. Recovery time was determined for each individual and variable by comparing the 3-day average with the confidence interval of the control phase. Recovery time was predicted by Cox regression analyses. Recovery times of all variables except health complaints were predicted by stress-related fatigue. Half of the individuals had recovered after 6 days, and 80% of the individuals had recovered after 8 days. The time necessary for recovery from work demands is determined by fatigue as a measure of resource depletion.

    Full Text Available Abstract Background Low grip strength is recognized as one of the characteristics of frailty, as are systemic inflammation and the sensation of fatigue. Contrary to maximal grip strength, the physical resistance of the muscles to fatigue is not often included in the clinical evaluation of elderly patients. The aim of this study was to investigate if the grip strength and the resistance of the handgrip muscles to fatigue are related to self-perceived fatigue, physical functioning and circulating IL-6 in independently living elderly persons. Methods Forty elderly subjects (15 female and 25 male, mean age 75 ± 5 years were assessed for maximal grip strength, as well as for fatigue resistance and grip work (respectively time and work delivered until grip strength drops to 50% of its maximum during sustained contraction, self perceived fatigue (VAS-Fatigue, Mob-Tiredness scale and the energy & fatigue items of the WHOQOL-100, self rated physical functioning (domain of physical functioning on the MOS short-form and circulating IL-6. Relationships between handgrip performance and the other outcome measures were assessed. Results In the male participants, fatigue resistance was negatively related to actual sensation of fatigue (VAS-F, p Conclusion Well functioning elderly subjects presenting less handmuscle fatigue resistance and weaker grip strength are more fatigued, experience more tiredness during daily activities and are more bothered by fatigue sensations. Body weight seems to play an important role in the relation of muscle performance to fatigue perception. Elderly patients complaining from fatigue should be physically assessed, both evaluating maximal grip strength and fatigue resistance, allowing the calculation of grip work, which integrates both parameters. Grip work might best reflect the functional capacity resulting from the development of a certain strength level in relation to the time it can be maintained.

    To determine the feasibility and efficacy of a physical activity behavioural change intervention in managing cancer-related fatigue among gynaecological cancer survivors during and post anti-cancer treatments. A two arm, single blind, randomised controlled trial was conducted within the Northern Ireland regional Cancer Centre. Thirty three sedentary gynaecological cancer survivors (stage I-III; ≤3 years post diagnosis), experiencing cancer-related fatigue (mild-severe) took part. Participants were randomly assigned to a behavioural change, moderate intensity physical activity intervention (n=16) or a Contact Control group (n=17). The primary outcome was fatigue (Multidimensional Fatigue Symptom Inventory-Short Form and Functional Assessment in Chronic Illness Therapy-Fatigue subscale). Secondary outcomes included quality of life, physical functioning, positive and negative affect, depression, body composition, sleep dysfunction and self-reported physical activity. Feasibility was assessed based on the recruitment rate, programme and physical activity adherence and participants' programme evaluation, including optional focus groups (n=16). Twenty five percent of eligible women took part (33/134). Participants were 8.7 (SD=9.1) months post diagnosis, with a mean age of 53 (SD=10.3) years. The majority of the sample had a diagnosis of ovarian (n=12) or endometrial cancer (n=11). Significant differences favouring the intervention group were observed for fatigue at 12 weeks and 6 months follow-up (12 week: mean difference=-11.06; 95% confidence interval (CI)=-21.89 to -0.23; effect size (d)=0.13; p=0.046; 6 month: mean difference=-19.48; 95% CI=-19.67 to -19.15; effect size (d)=0.20; p=0.01). A mean of 10 calls (SD=1.2 calls) were delivered to the Physical Activity Group, and 10 (SD=1.6 calls) to the CC group. The intervention was positively perceived based on exit questionnaire and focus group findings. A physical activity behavioural change intervention for

    To explore and determine relationship between psychosocial factors and work-related fatigue among emergency and critical care nurses in Brunei. Cross-sectional study conducted on all emergency and critical care nurses across Brunei public hospitals from February to April 2016. 201 nurses participated in the study (82% response rate). A total of 36% of the variance of chronic fatigue was explained by stress, trust in management, decision latitude, self-rated health, and work-family conflict. Burnout, self-rated health, commitment to workplace, and trust in management explained 30% of the variance of acute fatigue. Stress, work-family conflict and reward explained 28% of the variance of intershift recovery after controlling for significant sociodemographic variables. Smoking was identified as an important sociodemographic factor for work-related fatigue. Psychosocial factors were good predictors of work-related fatigue. A range of psychosocial factors were established, however more research is required to determine all possible causation factors of nurses' work-related fatigue.

    Fatigue is a distressing symptom many cancer patients experience even after completion of treatment. Although theory and empirical evidence indicate that negative cognitions perpetuate fatigue after completion of treatment, insight into how this process unfolds in daily life is limited. This study used an intensive longitudinal design to investigate the reciprocal relationship between catastrophizing and fatigue in daily life and whether affective and behavioral processes mediate these relationships. Post-treatment colorectal cancer patients (n = 101) completed daily diaries (14 days, 3 times daily) regarding their fatigue, catastrophizing, positive and negative affect, and physical activity. Multilevel modeling was applied to investigate within-person associations within days. Analyses revealed a positive reciprocal relationship between fatigue and catastrophizing throughout the day. That is, high levels of catastrophizing were associated with increases in fatigue within patients. In turn, but to a lesser extent, high levels of fatigue predicted increases in catastrophizing at the next assessment. Low positive affect and high negative affect mediated the effect of catastrophizing on increases in fatigue. Only negative affect mediated the reverse relationship. Physical activity did not mediate either relationship. This study provides evidence for a mutually reinforcing relationship between catastrophizing and fatigue in daily life, which might explain the perpetuation of fatigue after completion of cancer treatment. Fatigue-specific cognitive behavior therapy could be improved by educating patients about this daily reciprocal relationship, train them to quickly replace catastrophizing thoughts in daily life, and help them to cope with affective changes induced by fatigue.

    Full Text Available This study aimed to investigate the fatiguing characteristics of muscle-tendon units (MTUs within skeletal muscles during static isometric contraction tasks. The deltoid was selected as the target muscle and three head-related static isometric contraction tasks were designed to activate three heads of the deltoid in different modes. Nine male subjects participated in this study. Surface electromyography (SEMG signals were collected synchronously from the three heads of the deltoid. The performances of five SEMG parameters, including root mean square (RMS, mean power frequency (MPF, the first coefficient of autoregressive model (ARC1, sample entropy (SE and Higuchi’s fractal dimension (HFD, in quantification of fatigue, were evaluated in terms of sensitivity to variability ratio (SVR and consistency firstly. Then, the HFD parameter was selected as the fatigue index for further muscle fatigue analysis. The experimental results demonstrated that the three deltoid heads presented different activation modes during three head-related fatiguing contractions. The fatiguing characteristics of the three heads were found to be task-dependent, and the heads kept in a relatively high activation level were more prone to fatigue. In addition, the differences in fatiguing rate between heads increased with the increase in load. The findings of this study can be helpful in better understanding the underlying neuromuscular control strategies of the central nervous system (CNS. Based on the results of this study, the CNS was thought to control the contraction of the deltoid by taking the three heads as functional units, but a certain synergy among heads might also exist to accomplish a contraction task.

    2016-01-01

    Several authors have suggested that burned out patients do not form a homogeneous group and that subgroups should be considered. The identification of these subgroups may contribute to a better understanding of the burnout construct and lead to more specific therapeutic interventions. Subgroup analysis may also help clarify whether burnout is a distinct entity and whether subgroups of burnout overlap with other disorders such as depression and chronic fatigue syndrome. In a group of 113 clinically diagnosed burned out patients, levels of fatigue, depression, and anxiety were assessed. In order to identify possible subgroups, we performed a two-step cluster analysis. The analysis revealed two clusters that differed from one another in terms of symptom severity on the three aforementioned measures. Depression appeared to be the strongest predictor of group membership. These results are considered in the light of the scientific debate on whether burnout can be distinguished from depression and whether burnout subtyping is useful. Finally, implications for clinical practice and future research are discussed. PMID:26869983

    The web-based computer-tailored Kanker Nazorg Wijzer (Cancer Aftercare Guide) supports cancer survivors with psychosocial issues during cancer recovery. The current study investigates whether the 6-month effects in increasing emotional and social functioning and reducing depression and fatigue hold at 12 months from baseline. Moreover, it explores whether patient characteristics moderate the 6- and 12-month intervention effectiveness. Cancer survivors from 21 Dutch hospitals (November 2013-June 2014) were randomized to an intervention (n = 231) or a wait-list control group (n = 231). Intervention effects on emotional and social functioning (EORTC QLQ-C30), depression (HADS), and fatigue (CIS) were evaluated through multilevel linear regression analyses. At 12 months from baseline, the intervention group no longer differed from the control group in emotional and social functioning, depression, and fatigue. Moderator analyses indicated that, at 6 months, the intervention was effective in improving social functioning for men (d = 0.34), reducing fatigue for participants ≤56 years (d = 0.44), and reducing depression for participants who received chemotherapy (d = 0.36). At 12 months, participants with a medium educational level reported higher social functioning (d = 0.19), while participants with a low educational level reported lower social functioning (d = 0.22) than participants with a similar educational level in the control group. The intervention gave cancer patients a head start to psychological recovery after the end of cancer treatment. The control group caught up in the long run. The Cancer Aftercare Guide expedited recovery after cancer treatment. Being a low intensity, easy accessible, and relatively low cost intervention, it could serve as a relevant step in recovery and stepped care.

    Design fatigue calculations normally cover a service life of 40 years. Based on design transients with a specified number of cycles the evaluations have to prove that the fatigue usage after 40 years will stay below 1. In 40+ years of operation real loads can differ much from design loads so that premature ageing can occur. For long term operation, monitoring of real loads and detailed fatigue analysis for selected locations can be used to optimize operational modes in order to reduce the loads causing fatigue. As a result fatigue usage can be kept below 1 even for 60+ years. (author)

    2006-05-03

    To examine the relationship among sick leave benefits, employment patterns, individual characteristics, and fatigue in patients receiving radiation therapy. Prospective, longitudinal design. A community hospital radiation oncology department. 77 patients receiving radiation therapy to the breast, chest, head and neck, pelvis, or prostate. All were employed at the time of diagnosis. The Piper Integrated Fatigue Model guided the study. The Revised Piper Fatigue Scale (PFS), Brief Fatigue Inventory, and a single-item scale were used to measure five dimensions of subjective fatigue. Sick leave, employment, individual characteristics, and fatigue were measured at baseline, weekly during treatment, and at one month post-treatment. Employment patterns, availability of sick leave benefits, and fatigue. Mean total fatigue scores on the PFS ranged from 0-4.77 at baseline (mean = 0.46, SD = 0.93), 0-8.77 at the completion of treatment (mean = 2.84, SD = 2.40), and 0-4.82 at one month post-treatment (mean = 0.77, SD = 1.20). Side effects, education, living situation, age, treatment site, and work were associated with fatigue along the trajectory of radiation therapy. Study participants who were working at the end of radiation had lower fatigue scores than those who were not. Availability of sick leave benefits was associated with employment patterns during treatment. Work may have benefits during radiation therapy but may be affected by radiation therapy-related fatigue. Management of treatment side effects, including fatigue, may help patients remain in the workforce during radiation.

    As one of the main causes of traffic accidents, driving fatigue deserves researchers' attention and its detection and monitoring during long-term driving require a new technique to realize. Since functional near-infrared spectroscopy (fNIRS) can be applied to detect cerebral hemodynamic responses, we can promisingly expect its application in fatigue level detection. Here, we performed three different kinds of experiments on a driver and recorded his cerebral hemodynamic responses when driving for long hours utilizing our device based on fNIRS. Each experiment lasted for 7 hours and one of the three specific experimental tests, detecting the driver's response to sounds, traffic lights and direction signs respectively, was done every hour. The results showed that visual stimulus was easier to cause fatigue compared with auditory stimulus and visual stimulus induced by traffic lights scenes was easier to cause fatigue compared with visual stimulus induced by direction signs in the first few hours. We also found that fatigue related hemodynamics caused by auditory stimulus increased fastest, then traffic lights scenes, and direction signs scenes slowest. Our study successfully compared audio, visual color, and visual character stimulus in sensitivity to cause driving fatigue, which is meaningful for driving safety management.

    Stress and fatigue from effortful listening may compromise well-being, learning, and academic achievement in school-aged children. The aim of this study was to investigate the effect of a signal-to-noise ratio (SNR) typical of those in school classrooms on listening effort (behavioral and pupillometric) and listening-related fatigue (self-report and pupillometric) in a group of school-aged children. A sample of 41 normal-hearing children aged 8-11years performed a narrative speech-picture verification task in a condition with recommended levels of background noise ("ideal": +15dB SNR) and a condition with typical classroom background noise levels ("typical": -2dB SNR). Participants showed increased task-evoked pupil dilation in the typical listening condition compared with the ideal listening condition, consistent with an increase in listening effort. No differences were found between listening conditions in terms of performance accuracy and response time on the behavioral task. Similarly, no differences were found between listening conditions in self-report and pupillometric markers of listening-related fatigue. This is the first study to (a) examine listening-related fatigue in children using pupillometry and (b) demonstrate physiological evidence consistent with increased listening effort while listening to spoken narratives despite ceiling-level task performance accuracy. Understanding the physiological mechanisms that underpin listening-related effort and fatigue could inform intervention strategies and ultimately mitigate listening difficulties in children.

    While work-related fatigue has become an issue of concern among European employees, the relationship between fatigue, depression and work-related stressors is far from clear. The purposes of this study were (1) to determine the associations of fatigue with work-related stressors, severe medical disease, health behavior and depression in the working population and (2) to determine the unique impact of work-related stressors on fatigue. We used cross-sectional data of N = 7,930 working participants enrolled in the Gutenberg Health Study (GHS) from 2007 to 2012 filled out the Personal Burnout Scale (PBS) of the Copenhagen Psychosocial Questionnaire (COPSOQ), the PHQ-9, and a list of work-related stressors. A total of 27.5% reported increased fatigue, esp. women, younger persons with a lower social status and income, smokers, severely medically ill, previously and currently depressed participants. Fatigue was consistently associated with severe medical disease, health behavior and depression, which need to be taken into account as potential confounders when analyzing its relationship to work-related strains. Depression was consistently associated with work-related stressors. However, after statistically partialling out depression, fatigue was still significantly associated with work-related stress. Fatigue as an indicator of allostatic load is consistently associated with work-related stressors such as work overload after controlling for depression. The brief Personal Burn-out Scale is suitable for assessing work-related fatigue in the general population.

    Testicular cancer survivors (TCS) are at increased risk of cancer-related fatigue (CRF), psychosocial impairment, and poor mental health-related quality of life (HRQoL). Here, we examine the effects of high-intensity interval training (HIIT) on patient-reported outcomes (PROs) in TCS. Secondarily, we explore cardiorespiratory fitness as a mediator of intervention effects and select baseline characteristics as moderators of intervention effects. TCS (n = 63) were randomly assigned to 12 weeks of supervised HIIT or usual care (UC). PROs included CRF, depression, anxiety, stress, self-esteem, sleep quality, and HRQoL assessed at baseline, post-intervention, and 3-month follow-up. TCS (median 7 years postdiagnosis) completed 99% of training sessions and achieved 98% of target training intensity. ANCOVA revealed that, compared to UC, HIIT significantly improved post-intervention CRF (p = 0.003), self-esteem (p = 0.029), and multiple HRQoL domains (ps ≤ 0.05). Effects on CRF (p = 0.031) and vitality (p = 0.015) persisted at 3-month follow-up. Cardiorespiratory fitness changes mediated CRF and HRQoL improvements. CRF effects were larger for TCS with an inactive lifestyle, lower fitness, higher testosterone, and clinical fatigue at baseline. HIIT significantly improves CRF and HRQoL in TCS. Mediation by cardiorespiratory fitness and moderation by clinical characteristics suggests opportunities for targeted exercise interventions to optimise PROs in TCS.

    To investigate the prevalence of breast-related stereotype threat and its effects on a symptom cluster consisting of anxiety, depression and fatigue and on each symptom. The stereotype that breasts are a sign of women's femininity results in patients with breast cancer fearing diminished femininity and rejection, which may induce psychological problems that co-occur as a symptom cluster. Cross-sectional study. A total of 131 patients with breast cancer postmastectomy completed the study. A question measuring breast-related stereotype threat, the Hospital Anxiety and Depression Scale and the Functional Assessment of Chronic Illness Therapy-Fatigue Scale were used to assess their breast-related stereotype threat and symptoms of anxiety, depression and fatigue. Of the 131 patients who answered the breast-related stereotype threat question, 86 (65·6%) reported breast-related stereotype threat. They did not differ significantly in social and clinical characteristics compared with those without the stereotype, but did report significantly higher levels of the symptom cluster and each symptom (anxiety, depression and fatigue). The odds ratios of the stereotype were significant for the symptom cluster, depression and fatigue (odds ratios = 2·52-3·98, p stereotype threat was common in patients with breast cancer. There was about a twofold increase in their risk of experiencing the symptom cluster and symptoms of depression and fatigue. In clinical practice, breast-related stereotype threat should be measured together with prevalent symptoms (e.g. anxiety, depression and fatigue) in patients with breast cancer. Our findings will aid the development of interventions for improving the mental health of women with breast cancer. © 2016 John Wiley & Sons Ltd.

    Full Text Available Xenotropic murine leukemia virus-related virus (XMRV was first reported in 2006 in a study of human prostate cancer patients with genetic variants of the antiviral enzyme, RNase L. Subsequent investigations in North America, Europe, Asia, and Africa have either observed or failed to detect XMRV in patients (prostate cancer, chronic fatigue syndrome-myalgic encephalomyelitis (CFS-ME, and immunosuppressed with respiratory tract infections or normal, healthy, control individuals. The principal confounding factors are the near ubiquitous presence of mouse-derived reagents, antibodies and cells, and often XMRV itself, in laboratories. XMRV infects and replicates well in many human cell lines, but especially in certain prostate cancer cell lines. XMRV also traffics to prostate in a nonhuman primate model of infection. Here, we will review the discovery of XMRV and then focus on prostate cancer-related research involving this intriguing virus.

    Full Text Available Backgroud:Cancer-associated fatigue and the chronic adverse effects of cancer therapy can be reduced by Lipid Replacement Therapy (LRT using membrane phospholipid mixtures given as food supplements.Methods:This is a review of the published literature on LRT and its uses.Results: LRT significantly reduced fatigue in cancer patients as well as patients suffering from chronic fatiguing illnesses and other medical conditions. It also reduced the adverse effects of chemotherapy, resulting in improvements in incidence of fatigue, nausea, diarrhea, impaired taste, constipation, insomnia and other quality of life indicators. In other diseases, such as chronic fatigue syndrome, fibromyalgia syndrome and other chronic fatiguing illnesses, LRT reduced fatigue by 35.5-43.1% in different clinical trials and increased mitochondrial function.Conclusions: LRT formulations appear to be useful as non-toxic dietary supplements for direct use or placed in functional foods to reduce fatigue and restore mitochondrial and other cellular membrane functions. Formulations of LRT phospholipids are suitable for addition to variousfood products for the treatment of a variety of chronic illnesses as well as their application inanti-aging and other health supplements and products.

    Fatigue during cancer treatment is associated with depression. Neurotrophic factors play a major role in depression and stress and might provide insight into mechanisms of fatigue. This study investigated the association between plasma concentrations of three neurotrophic factors (BDNF, brain-derived neurotrophic factor; GDNF, glial-derived neurotrophic factor; and SNAPIN, soluble N-ethylmaleimide sensitive fusion attachment receptor-associated protein) and initial fatigue intensification during external beam radiation therapy (EBRT) in euthymic non-metastatic prostate cancer men. Fatigue, as measured by the 13-item Functional Assessment of Cancer Therapy-Fatigue (FACT-F), and plasma neurotrophic factors were collected at baseline (prior to EBRT) and mid-EBRT. Subjects were categorized into fatigue and no fatigue groups using a > 3-point change in FACT-F scores between the two time points. Multiple linear regressions analysed the associations between fatigue and neurotrophic factors. FACT-F scores of 47 subjects decreased from baseline (43.95 ± 1.3) to mid-EBRT (38.36 ± 1.5, P fatigue. SNAPIN levels were associated with fatigue scores (r s = 0.43, P = 0.005) at baseline. A significant decrease of BDNF concentration (P = 0.008) was found in fatigued subjects during EBRT (n = 39). Baseline SNAPIN and decreasing BDNF levels may influence worsening fatigue during EBRT. Further investigations are warranted to confirm their role in the pathophysiology and therapeutics of fatigue.

    Most health-related quality of life assessments are designed for either children or adults and have not been evaluated for adolescent and young adult survivors of pediatric cancer. The objective of this study was to examine the feasibility, reliability, and validity of the Pediatric Quality of Life Inventory (PedsQL ™ Generic Core Scales, Cancer Module, and Multidimensional Fatigue Scale in adult survivors of pediatric cancer. Adult survivors (n = 64; Mean age 35 year old; >2 years after treatment) completed the PedsQL™ Generic Core Scales, Cancer Module, and Multidimensional Fatigue Scale. Feasibility was examined with floor and ceiling effects; and internal consistency was determined by Cronbach's coefficient alpha calculations. Inter-factor correlations were also assessed. Significant ceiling effects were observed for the scales of social function, nausea, procedural anxiety, treatment anxiety, and communication. Internal consistency for all subscales was within the recommended ranges (α ≥ 0.70). Moderate to strong correlations between most Cancer Module and Generic Core Scales (r = 0.25 to r = 0.76) and between the Multidimensional Fatigue Scale and Generic Core Scales (r = 0.37 to r = 0.73). The PedsQL™ Generic Core Scales, Cancer Module, and Multidimensional Fatigue Scale appear to be feasible for an older population of pediatric cancer survivors; however, some of the Cancer Module Scales (nausea, procedural/treatment anxiety, and communication) were deemed not relevant for long-term survivors. More information is needed to determine whether the issues addressed by these modules are meaningful to long-term adult survivors of pediatric cancers. Copyright © 2012 Wiley Periodicals, Inc.

    Cancer patients can experience work-specific cognitive symptoms post return to work (RTW). The study aims to: 1) describe the course of work-specific cognitive symptoms in the first 18 months post RTW, and 2) examine the associations of work characteristics, fatigue and depressive symptoms with work-specific cognitive symptoms over time. This study used data from the 18-months 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 months follow-up; linear regression analyses with generalised estimating equations (GEE) were used to examine associations over time. Working cancer patients diagnosed 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=31.9, CI=23.1, 26.4) compared to executive function symptoms (M=19.3; CI=17.6, 20.9). Cancer patients holding a job with both manual and non-manual tasks reported less work-specific cognitive symptoms (unstandardized regression coefficient b=-4.80; CI=-7.76, -1.83) over time, compared to cancer patients with a non-manual 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). 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. This article is protected by copyright. All rights reserved.

    The aim of this study was to examine the relationship between serum C-terminal agrin fragment (CAF) concentrations and neuromuscular fatigue in older adults. Twenty-two healthy older men and women volunteered for this study. Resting fasted blood samples were collected and prepared for measurement of serum CAF concentration by a commercially available ELISA kit. The onset of neuromuscular fatigue was measured by monitoring electromyographic fatigue curves from the vastus lateralis muscle using the physical working capacity at fatigue threshold (PWCFT ) test. A significant inverse correlation for men was observed between CAF and PWCFT (r = -0.602; P = 0.05), but not for women (r = 0.208; P = 0.54). After controlling for age and body mass index, significant correlations (r = -0.69; P = 0.042) remained for men, but not for women (r = 0.12; P = 0.76). These data suggest that serum CAF concentrations were significantly related to the onset of neuromuscular fatigue independent of age and BMI in men only. © 2014 Wiley Periodicals, Inc.

    This study evaluated the efficacy of an intervention combining the Valencia model of waking hypnosis with cognitive-behavioral therapy (VMWH-CBT) in managing cancer-related pain, fatigue, and sleep problems in individuals with active cancer or who were post-treatment survivors. We hypothesized that four sessions of VMWH-CBT would result in greater improvement in participants' symptoms than four sessions of an education control intervention. Additionally, we examined the effects on several secondary outcome domains that are associated with increases in these symptoms (depression, pain interference, pain catastrophizing, and cancer treatment distress). The study design was a randomized controlled crossover clinical trial comparing the VMWH-CBT intervention with education control. Participants (N = 44) received four sessions of both treatments, in a counterbalanced order (n = 22 per order condition). Participants were 89% female (N = 39) with mean age of 61 years (SD = 12.2). They reported significantly greater improvement after receiving the active treatment relative to the control condition in all the outcome measures. Treatment gains were maintained at 3-month follow-up. This study supports the beneficial effects of the VMWH-CBT intervention relative to a control condition and that treatment gains remain stable. VMWH-CBT-trained clinicians should be accessible for managing symptoms both during and after cancer treatment, though the findings need to be replicated in larger samples of cancer survivors.

    Despite advances in early detection and effective treatment, cancer remains one of the most feared diseases. Among the most common side effects of cancer and treatments for cancer are pain, depression, and fatigue. Although research is producing increasingly hopeful insights into the causes and cures for cancer, efforts to manage the side effects of the disease and its treatments have not kept pace. The challenge that faces us is how to increase awareness of the importance of recognizing and actively addressing cancer-related distress. The National Institutes of Health (NIH) convened a State-of-the-Science Conference on Symptom Management in Cancer: Pain, Depression, and Fatigue to examine the current state of knowledge regarding the management of pain, depression, and fatigue in individuals with cancer and to identify directions for future research. Specifically, the conference examined how to identify individuals who are at risk for cancer-related pain, depression, and/or fatigue; what treatments work best to address these symptoms when they occur; and what is the best way to deliver interventions across the continuum of care. STATE-OF-THE-SCIENCE PROCESS: A non-advocate, non-Federal, 14-member panel of experts representing the fields of oncology, radiology, psychology, nursing, public health, social work, and epidemiology prepared the statement. In addition, 24 experts in medical oncology, geriatrics, pharmacology, psychology, and neurology presented data to the panel and to the conference audience during the first 1.5 days of the conference. The panel then prepared its statement, addressing the five predetermined questions and drawing on submitted literature, the speakers' presentations, and discussions held at the conference. The statement was presented to the conference audience, followed by a press conference to allow the panel to respond to questions from the media. After its release at the conference, the draft statement was made available on the Internet

    As the number of survivors of Hodgkin's lymphoma (HL) increases, there has been a growing interest in long-term treatment-related side effects and their impact on the quality of life (QoL). The aim of this study was to assess the association of social network and social support with the QoL and fatigue among long-term HL survivors. A total of 200 HL survivors were included. The generic Short Form-12 (SF-12) questionnaire, the QoL cancer survivor's questionnaire (QOL-CS), and the Multidimensional Fatigue Inventory were used to assess QoL and fatigue. Social network and social support were evaluated with the Social Support Survey. Social network and all social support measures were favorably associated with two or more SF-12 scales, mainly with physical functioning and the mental health scales. Social network and social support dimensions were also associated with better QOL-CS scores. Affective support, informational support, positive interaction, and emotional support were associated with less fatigue. Both social network and social support are associated with better QoL and lower levels of fatigue in HL survivors. This information may be useful to health professionals and community organizations in implementing effective interventions to improve these patients' quality of life.

    To (1) evaluate existing eHealth/mHealth interventions developed to help manage cancer-related fatigue (CRF); and (2) summarize the best available evidence on their effectiveness. A comprehensive literature search of PubMed, MEDLINE, EMBASE, and the Cochrane Library up to November 2016 was conducted. Study outcomes were extracted, tabulated, and summarized. Random effects meta-analyses were conducted for the primary outcome (fatigue), and the secondary outcomes quality of life and depression, yielding pooled effect sizes (r), and 95% confidence intervals (CI). For eHealth interventions, our search of published papers identified 9 completed studies and 6 protocols for funded projects underway. No studies were identified for mHealth interventions that met our inclusion criteria. A meta-analysis of the 9 completed eHealth studies revealed a statistically significant beneficial effect of eHealth interventions on CRF (r = .27, 95% CI [.1109 - .4218], P eHealth interventions were more efficacious then self-guided interventions (r = .58, 95% CI: [.3136 - .5985, P eHealth interventions appear to be effective for managing fatigue in cancer survivors with CRF. Continuous development of eHealth interventions for the treatment of CRF in cancer survivors and their testing in long-term, large-scale efficacy outcome studies is encouraged. The degree to which mHealth interventions can change CRF in cancer survivors need to be assessed systematically and empirically. Copyright © 2017 John Wiley & Sons, Ltd.

    We investigated the prevalence of sleep disturbance and psychological distress in lung cancer patients. We also examined the association between sleep disturbance and psychological distress, pain, fatigue, and quality of life in the same population. Fifty lung cancer patients were evaluated. Sleep disturbance was assessed using the Athens Sleep Insomnia Scale (AIS) and psychological distress using the Hospital Anxiety and Depression Scale (HADS). Quality of life (QOL), pain, and fatigue were assessed employing the European Organization of Research and Treatment Quality of Life Questionnaire-Cancer 30 (EORTC QLQ-C30). We observed that 56% of lung cancer patients had sleep disturbance (AIS score ≥6) and 60% had psychological distress (total HADS score ≥11). Patients with sleep disturbance had a HADS score of 14.6 ± 5.8, a fatigue score of 45.3 ± 22.0, and a pain score of 27.2 ± 26.2. In contrast, patients without sleep disturbance had a lower HADS score of 9.9 ± 8.1 (p psychological distress. Additionally, the type of sleep disturbance was related to other patient factors, including whether or not they received chemotherapy.

    One of the common side effects of cancer is fatigue that affects patients' life quality and leads to disability. Exercise has an important role in improving these patients' life quality and can be used as a complementary treatment. Moreover, there are few studies on the impact of exercise on fatigue among patients with colon cancer. Therefore, the present study investigated the effects of exercise on the severity of fatigue in patients with colorectal cancer who underwent chemotherapy in Ahwaz. In a quasi-experimental study, the adults with colorectal cancer were enrolled. The sample included 36 people. The study environment included adult hematology and chemotherapy wards of Shefa Hospital in Ahwaz. Data were collected using a demographic form and a questionnaire in order to measure the severity of fatigue. Then, the patients had 40 minutes of exercise, 3 times a week for 4 weeks. The effect of exercise versus fatigue intensity was measured at the end of every week. Data were analyzed using SPSS software. The mean of the fatigue severity in the weeks after exercise was significantly different from the week before it. Friedman test showed significant differences between all the weeks before and after the exercise. The mean of the fatigue severity was 3.69 on the week 0 (before the exercise), and decreased to 3.57 on the first week after exercise, 3.46 on the second week, 2.58 on the third week, and 1.69 on the forth week. Considering the results of this study, exercise and work-out can be an effective factor in reducing fatigue in patients.

    Background/aim: The Cancer Fatigue Scale (CFS) was developed to evaluate the severity of fatigue in patients with breast cancer. The aim of this study is to translate and culturally adapt a Turkish version and investigate the validity and reliability of the CFS in Turkish patients with fatigue symptoms. Materials and methods: Eighty participants completed the Turkish version of the CFS for breast cancer and the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire ″Core 30″ (EORTC QLQ-C30). Test-retest reliability was evaluated by repeating the CFS with a 7-day interval. Results: The CFS demonstrated high test-retest reliability (ICC = 0.95) and good internal consistency (Cronbach′s alpha = 0.74) for all domains. The Kaiser-Meyer-Olkin measure of sampling adequacy was found to be 0.819, which is considered to be satisfactory (>0.5). Correlations between domains of CFS physical and EORTC physical (r: 0.77), CFS cognitive and EORTC cognitive (r: 0.70), and CFS physical and EORTC fatigue (r: 0.80) were found to be significant. Conclusion: The Turkish version of the CFS is a reliable and valid instrument to assess physical, effective, and cognitive dimensions of fatigue. The CFS may be used to evaluate the severity of fatigue in Turkish-speaking breast cancer patients.

    Fatigue and poor sleep are two of the most common and most distressing symptoms for adolescents with cancer. These 2 symptoms concurrently heighten distress, further decreasing quality of life (QoL). The aims of this study were to describe the degree of exercise involvement, fatigue, sleep quality, and QoL among adolescents with cancer and to determine whether exercise mediates the relationships between (a) fatigue and QoL and (b) sleep quality and QoL. A cross-sectional study of 100 participants was conducted. Multiple regression was performed to examine the mediation relationship. Participants in the off-treatment group had a significantly higher degree of exercise involvement, as well as less fatigue, greater sleep quality, and less QoL distress. Exercise partially mediated the adverse effect of fatigue on QoL for adolescents undergoing cancer treatment, accounting for 49.80% of the total variation; exercise partially mediated the adverse effect of poor sleep on QoL for adolescents both in treatment and in survivorship, accounting for 42.06% and 28.71% of the total variations, respectively. Exercise partially mediated the relationship between fatigue and QoL for adolescents in cancer treatment and partially mediated the relationship between sleep quality and QoL both for those in cancer treatment and for those in survivorship. Developing tailored exercise programs based on both treatment status and the degree of fatigue and sleep quality is important. In-service education that enhances nurses' awareness of the importance of exercise in improving adolescents' QoL is recommended.

    This article takes a new direction in exploring HIV-related fatigue by adopting a qualitative interactionist approach. We analyse the social meanings attributed to fatigue among people living with HIV in France, the social gains and losses of its visibility and the social frames that condition its discursive and physical expression. The two-part methodology combines grounded theory analysis of 50 transcribed unstructured interviews conducted across France and participant observations within four HIV-related associations. Results reveal that the visibility of fatigue is in part dependent on the visibility of this stigmatized illness. The expression of fatigue is therefore closely linked with disclosure and concerns about HIV stigma. The degree to which HIV and HIV-related fatigue are rendered (in)visible also depends on structural factors including gender prescriptions, as well as context effects such as the type of social or 'care' relations involved in the social frame of interaction.

    To examine the relationship between physical performance and fatigue in child and adolescent cohorts during the first three cycles of chemotherapy. Prospective, observational design. Two pediatric cancer centers in the upper Midwest region of the United States. 16 children and 14 adolescents newly diagnosed with cancer. Standardized instruments were administered during the first and third cycles of chemotherapy. Instruments included physical performance tests (Timed Up and Down Stairs [TUDS] and the 6-Minute Walk Test [6MWT]) and a self-report fatigue scale. Fatigue and physical performance. In the child cohort, physical performance appeared to improve and fatigue diminished from cycle 1 to 3 of chemotherapy. When time on TUDS decreased, fatigue tended to decrease; when 6MWT distance increased, fatigue decreased. In the adolescent cohort, fatigue seemed to decrease but physical performance measures evidenced little change. Correlations between changes in the physical performance variables and fatigue were not significant. Fatigue may decrease early in treatment as disease symptoms resolve. Fatigue in the child cohort was related to physical performance, which is consistent with previous studies that defined fatigue in children as primarily a physical sensation. Findings in the adolescent cohort support research that defined adolescent fatigue as more complex with mental, emotional, and physical components. Knowing how fatigue relates to physical performance in children and adolescents informs the nurse in educating patients and families about symptom management.

    The fatigue associated with five newly approved vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) (regorafenib, vandetanib, cabozantinib, lenvatinib, axitinib) is poorly understood. We conducted this systematic review to fully investigate the fatigue associated with these VEGFR-TKIs in cancer patients. Relevant studies of randomized controlled trials in cancer patients treated with the five VEGFR-TKIs were retrieved and a systematic evaluation was conducted. EMBASE, MEDLINE, and PubMed were searched for articles published until March 2017. Thirteen randomized controlled trials and 4395 patients were included. The current analysis suggested that the use of five newly approved VEGFR-TKIs increased the risk of all-grade fatigue (1.43; 95% CI 1.23-1.66; p fatigue (1.97; 95% CI1.44-2.70; p fatigue varied significantly within drug type, but high-grade fatigue did not. The RR of all-grade and high-grade fatigue did not vary significantly according to cancer type, treatment line, and treatment duration. The risk of high-grade fatigue may vary with treatment duration, whereas all-grade fatigue may not. The available data suggest that the use of the five newly approved VEGFR-TKIs is associated with a significantly increased risk of fatigue in cancer patients. Physicians should be aware of this adverse effect and should monitor cancer patients receiving these drugs.

    To evaluate the effects of reflexology treatment on quality of life, sleep disturbances, and fatigue in breast cancer patients during radiation therapy. A total of 72 women with breast cancer (stages 1-3) scheduled for radiation therapy were recruited. Women were allocated upon their preference either to the group receiving reflexology treatments once a week concurrently with radiotherapy and continued for 10 weeks or to the control group (usual care). The Lee Fatigue Scale, General Sleep Disturbance Scale, and Multidimensional Quality of Life Scale Cancer were completed by each patient in both arms at the beginning of the radiation treatment, after 5 weeks, and after 10 weeks of reflexology treatment. The final analysis included 58 women. The reflexology treated group demonstrated statistically significant lower levels of fatigue after 5 weeks of radiation therapy (p fatigue, quality of sleep, pain, and quality of life in breast cancer patients during radiation therapy. Reflexology prevented the decline in quality of life and significantly ameliorated the fatigue and quality of sleep of these patients. An encouraging trend was also noted in amelioration of pain levels.

    groups but additional post hoc analysis revealed that better quality of life significantly predicted higher NKCA regardless of therapy. Compared to WBRT, PBRT results in more rapid recovery from cancer-related fatigue with improved restoration of quality of life after radiation therapy. Additionally, better quality of life predicts higher NKCA against tumor targets, emphasizing the importance of fostering quality of life for women undergoing adjuvant radiation therapy.

    Full Text Available Objective: Patients receiving chemotherapy struggle with the side effects of this treatment. These side effects obligate the patients to use not only the pharmacological methods but also non-pharmacological relaxing methods. This study was conducted to determine the effect of reflexology on chemotherapy-induced nausea, vomiting, and fatigue in breast cancer patients. Methods: The study was conducted as a pretest–posttest experimental design. The study was conducted with sixty patients, thirty as the control and thirty as the experimental groups. A sociodemographic form, Rhodes index of nausea, vomiting, and retching (INVR, and Brief Fatigue Inventory (BFI were used to collect the data. Analysis of variance, t-test, percentage calculations, and Chi-square methods were used to evaluate the data. The data obtained were assessed using the “Statistical Package for Social Science 21.0” software. Results: It was determined that the difference between the total mean scores of INVR in the experimental and control groups was significant on the onset and first and second measurements, and the difference between total mean scores of development and distress between the groups was statistically significant in the third measurement (P < 0.05. The results of the study showed that the BFI mean scores of patients in the experimental group gradually decreased in the first, second, and third measurements (P < 0.05. Conclusions: The present study proved that reflexology decreased the experience, development, distress of nausea, vomiting, and retching as well as fatigue in the experimental group. Hence, the use of reflexology is recommended for chemotherapy-induced nausea, vomiting, and fatigue.

    Prostate cancer treatments are associated with a range of symptoms and physical side-effects. Cancer can also adversely impact on psychological wellbeing. Because many prostate cancer-related symptoms and side-effects are potentially modifiable, we investigated associations between symptoms and psychological wellbeing among prostate cancer survivors. Postal questionnaires were distributed to men diagnosed with prostate cancer 2-18 years previously identified through cancer registries. General and prostate cancer-specific symptoms were assessed using the EORTC QLQ-C30 and QLQ-PR25, with higher symptom scores indicating more/worse symptomatology. Psychological wellbeing was assessed by the DASS-21. Associations between symptoms and each outcome were investigated using multivariate logistic regression, controlling for socio-demographic and clinical factors. A total 3348 men participated (response rate = 54%). Seventeen percent (95%CI 15.2%-17.9%), 16% (95%CI 15.1%-17.8%) and 11% (95%CI 9.5%-11.8%) of survivors scored in the range for depression, anxiety and distress on the DASS scales, respectively. In multivariate models, risk of depression on the DASS scale was significantly higher in men with higher urinary and androgen deprivation therapy (ADT)-related symptoms, and higher scores for fatigue, insomnia and financial difficulties. Risk of anxiety on the DASS scale was higher in men with higher scores for urinary, bowel and ADT-related symptoms and fatigue, dyspnoea and financial difficulties. Risk of distress on the DASS scale was positively associated with urinary, bowel and ADT-related symptoms, fatigue, insomnia and financial difficulties. Cancer-related symptoms significantly predict psychological wellbeing among prostate cancer survivors. Greater use of interventions and medications and to alleviate symptoms might improve psychological wellbeing of prostate cancer survivors. Copyright © 2015 John Wiley & Sons, Ltd.

    Chemokines are key players of the cancer-related inflammation. Chemokine ligands and receptors are downstream of genetic events that cause neoplastic transformation and are abundantly expressed in chronic inflammatory conditions which predispose to cancer. Components of the chemokine system affect multiple pathways of tumor progression including: leukocyte recruitment, neo-angiogenesis, tumor cell proliferation and survival, invasion and metastasis. Evidence in pre-clinical and clinical settings suggests that the chemokine system represents a valuable target for the development of innovative therapeutic strategies.

  6. EFFICACIOUS PSYCHOLOGICAL TREATMENTS FOR REDUCING FATIGUE IN CANCER SURVIVORS: THE STATE OF THE QUESTION AND FUTURE PROSPECTS

    2015-09-01

    Full Text Available Cancer remains a major health problem worldwide. Due to the efficacy of the treatments and the improvements in healthcare systems, however, the number of cancer survivors has increased significantly over the years. Fatigue is one of the consequences of cancer that appears most frequently, causing significant changes in the lives of survivors. Different psychological treatments have been used to reduce fatigue in this patient group. Cognitive-behavioural techniques and mindfulness therapies are the ones that have the most data supporting their effectiveness, ahead of psycho-educational type interventions. The majority of studies, however, have been conducted with breast cancer survivors, and it would be desirable to test the effectiveness of these techniques with a greater variability of cancer types.

    Objective was to determine whether physical activity reduces the severity of fatigue in patients with cancer or hematopoietic stem cell transplant (HSCT) recipients. We conducted a meta-analysis of randomized trials comparing physical activity with control interventions for the management of fatigue in patients with cancer or HSCT recipients. There were 170 trials included. Physical activity reduced the severity of fatigue when compared to all control groups (standardized mean difference -0.49, 95% confidence interval -0.60 to -0.37; P fatigue although smaller effects were observed with resistance exercises (P interaction = 0.01). Other intervention and patient characteristics did not influence the effect of physical activity on the severity of fatigue. Physical activity was effective at reducing fatigue in patients with cancer and HSCT recipients across patient sub-groups. Determining the best approaches for safe implementation should be a priority. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Introduction: Driving crash is one of major concerns in all countries. Mental workload reflects the level of attention resources required to meet both objec­tive and subjective performance criteria, which may be affected by task demand, external support, and past experience. Mental workload has been commonly cited as a major cause of workplace and transportation accidents. The objective of this study was assessment of mental workload and its relation with fatigue among urban bus drivers in Tehran, Iran. Methods: In this descriptive and analytical study, the NASA-TLX workload scale and the Samn-Perelli fatigue scale were completed by 194 professional bus drivers. Descriptive statistics as well as correlation and regression analysis were performed for data processing. Results: The total mental workload had highest correlation with the physical demand(r=0.73, p<0.001, the mental demand (r=0.68, p<0.001 and the time pressure (r=0.58, p<0.001. The total fatigue perceived by bus driver had highest correlation with the frustration level (r=0.42, p<0.001, the time pressure (r=0.24, p<0.001 and the mental workload (r=0.21, p<0.001. Conclusion: Mental workload, physical workload and time pressure are important determinants of the total mental workload and fatigue perceived by urban bus drivers. A comprehensive intervention program, include work turnover, trip and work-rest scheduling as well as smoking cessation, was recommended to improve mental workload and fatigue

    New and more effective treatments for cancer have resulted in individuals living longer with a better quality of life. Many more survivors are employed in the workplace. Cancer is no longer only an issue for survivors and their families; it has become an issue for the employer and the workplace. This article describes survey results of 4,364 long term cancer survivors in which they were asked to respond to items describing their ability to work, job discrimination, and quality of life. Thirty-five percent of survivors were working at the time they completed the survey, and 8.5% considered themselves unable to work. This research has shown that age, gender, ethnic group, and cancer type affected the working status of the survivors. Of survivors continuing to work, 7.3% indicated they had experienced job discrimination. The results indicate most cancer survivors do not perceive employment related problems, and are readily assimilated into the work force. Job discrimination and the ability to work is a quality of life issue.

    To investigate the effects of oral zinc supplementation on fatigue intensity and quality of life of patients during chemotherapy for colorectal cancer. A prospective, randomized, double-blinded, placebo-controlled study was conducted with 24 patients on chemotherapy for colorectal adenocarcinoma in a tertiary care public hospital. The study patients received zinc capsules 35mg (Zinc Group, n=10) or placebo (Placebo Group, n=14) orally, twice daily (70mg/day), for 16 weeks, from the immediate postoperative period to the fourth chemotherapy cycle. Approximately 45 days after surgical resection of the tumor, all patients received a chemotherapeutic regimen. Before each of the four cycles of chemotherapy, the Functional Assessment of Chronic Illness Therapy-Fatigue scale was completed. We used a linear mixed model for longitudinal data for statistical analysis. The scores of quality of life and fatigue questionnaires were similar between the groups during the chemotherapy cycles. The Placebo Group presented worsening of quality of life and increased fatigue between the first and fourth cycles of chemotherapy, but there were no changes in the scores of quality of life or fatigue in the Zinc Group. Zinc supplementation prevented fatigue and maintained quality of life of patients with colorectal cancer on chemotherapy.

    This study assessed fatigue and its association with emotional labor and non-standard working hours among hotel workers. A structured self-administered questionnaire was distributed to 1,320 employees of five hotels located in Seoul. The questionnaire survey included questions concerning the participants' sociodemographics, health-related behaviors, job-related factors, emotional labor, and fatigue. Fatigue was assessed using the Multidimensional Fatigue Scale (MFS). Multiple logistic regression modeling was used to determine the associations between fatigue and emotional labor. Among male workers, there was a significant association between fatigue and both emotional disharmony (OR=5.52, 95% CI=2.35-12.97) and emotional effort (OR=3.48, 95% CI=1.54-7.86). These same associations were seen among the female workers (emotional disharmony: OR=6.91, 95% CI=2.93-16.33; emotional effort: OR=2.28, 95% CI=1.00-5.16). These results indicate that fatigue is associated with emotional labor and, especially, emotional disharmony among hotel workers. Therefore, emotional disharmony management would prove helpful for the prevention of fatigue.

    Fatigue and emotional reactivity are common among women suffering from breast cancer and might detrimentally affect these women's quality of life. This study evaluates if the stress management delivered either in a group or individual setting would improve fatigue and emotional reactivity among women with a newly diagnosed breast cancer. Participants (n = 304) who reported elevated levels of distress at three-month post-inclusion were randomised between stress management in a group (GSM) (n = 77) or individual (ISM) (n = 78) setting. Participation was declined by 149 women. Participants completed the Multidimensional Fatigue Inventory (MFI-20) and the Everyday Life Stress Scale (ELSS) at the time of inclusion, 3- and 12-month post-inclusion. Analyses were made according to intention to treat and per-protocol principles. Mann-Whitney tests were used to examine differences between the two intervention groups. No significant differences were detected between the GSM and ISM groups on fatigue or emotional reactivity. In addition, there were no changes over time for these outcomes. There were no differences between the two intervention arms with reference to fatigue or emotional reactivity; however, a clinically interesting finding was the low number of women who were interested in participating in a psychosocial intervention. This finding may have clinical implications when psychosocial support is offered to women with a newly diagnosed breast cancer and also in the planning of future studies.

    This study aims to evaluate the influences of sleep duration and sleep variability (SleepV), upon adolescents' school-related situations. The Health Behaviour in School-Aged Children (HBSC) survey is based on a self-completed questionnaire. The participants were 3164 pupils (53.7% girls), attending the 8th and 10th grades, 14.9 years old, and were inquired about subjective sleep duration during the week and weekends, SleepV, fatigue, difficulties in sleep initiation, school achievement, feelings towards schools, pressure with school work and skipping classes. Multiple regression models used, as dependent variables: (a) school achievement, (b) disliking school, (c) pressure with school work and (d) skipping classes, using as independent variables, each of the remaining school-related variables, fatigue, total sleep duration and difficulties in sleep initiation. The average sleep duration in the week and during weekdays was lower than recommended for these age groups, and almost half of students had high SleepV between weekdays and weekends. A logistic model revealed that the absence of SleepV was associated with lower perception of school work pressure, less frequent skipping classes, more infrequent fatigue and more infrequent difficulties in sleep initiation. Poor sleep quality, SleepV and insufficient sleep duration affected negatively school-related variables. © 2015 International Union of Psychological Science.

    The aim of this study is to co-create an evidence-based and theoretically informed web-based intervention (RESTORE) designed to enhance self-efficacy to live with cancer-related fatigue (CRF) following primary cancer treatment. A nine-step process informed the development of the intervention: (1) review of empirical literature; (2) review of existing patient resources; (3) establish theoretical framework; (4) establish design team with expertise in web-based interventions, CRF and people affected by cancer; (5) develop prototype intervention; (6) user testing phase 1; (7) refinement of prototype; (8) user testing phase 2; and (9) develop final intervention. Key stakeholders made a critical contribution at every step of intervention development, and user testing, which involved an iterative process and resulted in the final intervention. The RESTORE intervention has five sessions; sessions 1 and 2 include an introduction to CRF and goal setting. Sessions 3-5 can be tailored to user preference and are designed to cover areas of life where CRF may have an impact: home and work life, personal relationships and emotional adjustment. It is feasible to systematically 'co-create' an evidence-based and theory-driven web-based self-management intervention to support cancer survivors living with the consequences of cancer and its treatment. This is the first account of the development of a web-based intervention to support self-efficacy to manage CRF. An exploratory trial to test the feasibility and acceptability of RESTORE is now warranted. Copyright © 2015 John Wiley & Sons, Ltd.

    2017-12-01

    This study aims to examine the impact of work-related and personal resources on older workers' retirement intentions by studying the pathways (fatigue and work enjoyment) from resources to retirement intentions, the buffering role of resources for psychological job demands, in a cross-sectional and longitudinal timeframe. Longitudinal results on a subsample of full-time, older workers (n = 1642) from the Maastricht Cohort Study suggest that over four years of follow-up personal resources like personal mastery and perceived health related to less (prolonged) fatigue and more work enjoyment. Personal mastery also related to later retirement intentions. A work-related resource like decision authority related to less prolonged fatigue. (Prolonged) fatigue related to earlier retirement intentions, suggesting that fatigue may be a pathway to early retirement. Finally, little evidence was found for effect modification by resources. This prospective study indicates that work-related and personal resources may be useful for prolonging working careers. Practitioner Summary: To date, the impact of work-related and personal resources on older workers' retirement intentions is rarely studied. As this prospective study shows that resources may impact older workers' (prolonged) fatigue, work enjoyment and retirement intentions, the monitoring and fostering of resources is of importance for prolonging their working careers.

    Brief, valid measures of fatigue, a prevalent and distressing cancer symptom, are needed for use in research. This study's primary aim was to create a shortened version of the revised Piper Fatigue Scale (PFS-R) based on data from a diverse cohort of breast cancer survivors. A secondary aim was to determine whether the PFS captured multiple distinct aspects of fatigue (a multidimensional model) or a single overall fatigue factor (a unidimensional model). Breast cancer survivors (n = 799; stages in situ through IIIa; ages 29-86 years) were recruited through three SEER registries (New Mexico, Western Washington, and Los Angeles, CA) as part of the Health, Eating, Activity, and Lifestyle (HEAL) study. Fatigue was measured approximately 3 years post-diagnosis using the 22-item PFS-R that has four subscales (Behavior, Affect, Sensory, and Cognition). Confirmatory factor analysis was used to compare unidimensional and multidimensional models. Six criteria were used to make item selections to shorten the PFS-R: scale's content validity, items' relationship with fatigue, content redundancy, differential item functioning by race and/or education, scale reliability, and literacy demand. Factor analyses supported the original 4-factor structure. There was also evidence from the bi-factor model for a dominant underlying fatigue factor. Six items tested positive for differential item functioning between African-American and Caucasian survivors. Four additional items either showed poor association, local dependence, or content validity concerns. After removing these 10 items, the reliability of the PFS-12 subscales ranged from 0.87 to 0.89, compared to 0.90-0.94 prior to item removal. The newly developed PFS-12 can be used to assess fatigue in African-American and Caucasian breast cancer survivors and reduces response burden without compromising reliability or validity. This is the first study to determine PFS literacy demand and to compare PFS-R responses in African

    Purpose: To investigate whether symptom burden before and during preoperative chemoradiation therapy (CRT) for rectal cancer predicts for pathologic tumor response. Methods and Materials: Fifty-four patients with T3/T4/N+ rectal cancers were treated on a Phase II trial using preoperative capecitabine and concomitant boost radiotherapy. Symptom burden was prospectively assessed before (baseline) and weekly during CRT by patient self-reported questionnaires, the MD Anderson Symptom Inventory (MDASI), and Brief Fatigue Inventory (BFI). Survival probabilities were estimated using the Kaplan-Meier method. Symptom scores according to tumor downstaging (TDS) were compared using Student's t tests. Logistic regression was used to determine whether symptom burden levels predicted for TDS. Lowess curves were plotted for symptom burden across time. Results: Among 51 patients evaluated for pathologic response, 26 patients (51%) had TDS. Fatigue, pain, and drowsiness were the most common symptoms. All symptoms increased progressively during treatment. Patients with TDS had lower MDASI fatigue scores at baseline and at completion (Week 5) of CRT (p = 0.03 for both) and lower levels of BFI 'usual fatigue' at baseline. Conclusion: Lower levels of fatigue at baseline and completion of CRT were significant predictors of pathologic tumor response gauged by TDS, suggesting that symptom burden may be a surrogate for tumor burden. The relationship between symptom burden and circulating cytokines merits evaluation to characterize the molecular basis of this phenomenon.

    The aims of this study were to evaluate the health status of long-term breast cancer survivors (LTBCS) suffering from higher levels of fatigue, to highlight their needs, and to establish the key points of intervention support programs. A cross-sectional observational study was conducted at the Sport and Health Joint University Institute (iMUDS) between September 2016 and July 2017 with 80 LTBCS that were classified into non-fatigued (≤ 3.9) or fatigued (≥ 4) according to the Piper Fatigue Scale (PFS) total score. The instruments used were the European Organization for Research and Treatment of Cancer Core 30 and its breast cancer (BC) module, the Visual Analog Scale (VAS), the Brief Pain Inventory (BPI), the Scale for Mood Assessment (EVEA), the International Fitness Scale (IFIS), and the Charlson Comorbidity Index. The analysis revealed that 41.2% of LTBCS were considered moderately fatigued and showed significantly higher levels for the categories of "nausea and vomiting" (P = .005), "pain," "dyspnea" and "insomnia" (P < .001), "appetite loss" (P = .002), "financial difficulties" (P = .010), "systemic therapy side effects" (P < .001), "breast symptoms" and "arm symptoms" (P = .002), and "upset by hair loss" (P = .016). In addition, LTBCS presented significantly higher levels of pain in the affected and non-affected arm, "sadness-depression." "anxiety," "anger/hostility" (All: P < .001), and lower general physical fitness (P < .001). The rest of the variables did not show significant differences. LTBCS suffering from higher levels of fatigue had lower QoL, higher level of pain, worse mood state, and lower physical fitness.

    Full Text Available Question: Is there a dose-response effect of exercise on inflammation, fatigue and activity in cancer survivors? Design: Systematic review with meta-regression analysis of randomised trials. Participants: Adults diagnosed with cancer, regardless of specific diagnosis or treatment. Intervention: Exercise interventions including aerobic and/or resistance as a key component. Outcome measures: The primary outcome measures were markers of inflammation (including C-reactive protein and interleukins and various measures of fatigue. The secondary outcomes were: measures of activity, as defined by the World Health Organization's International Classification of Functioning, Disability and Health, including activities of daily living and measures of functional mobility (eg, 6-minute walk test, timed sit-to-stand and stair-climb tests. Risk of bias was evaluated using the PEDro scale, and overall quality of evidence was assessed using the Grades of Research, Assessment, Development and Evaluation (GRADE approach. Results: Forty-two trials involving 3816 participants were included. There was very low-quality to moderate-quality evidence that exercise results in significant reductions in fatigue (SMD 0.32, 95% CI 0.13 to 0.52 and increased walking endurance (SMD 0.77, 95% CI 0.26 to 1.28. A significant negative association was found between aerobic exercise intensity and fatigue reduction. A peak effect was found for moderate-intensity aerobic exercise for improving walking endurance. No dose-response relationship was found between exercise and markers of inflammation or exercise duration and outcomes. Rates of adherence were typically high and few adverse events were reported. Conclusions: Exercise is safe, reduces fatigue and increases endurance in cancer survivors. The results support the recommendation of prescribing moderate-intensity aerobic exercise to reduce fatigue and improve activity in people with cancer. Review registration: PROSPERO CRD

    The cause-effect relationship between lactic acid, acidosis, and muscle fatigue has been established in the literature. However, current experiments contradict this premise. Here, we describe an experiment developed by first-year university students planned to answer the following questions: 1) Which metabolic pathways of energy metabolism are responsible for meeting the high ATP demand during high-intensity intermittent exercise? 2) Which metabolic pathways are active during the pause, and how do they influence phosphocreatine synthesis? and 3) Is lactate production related to muscular fatigue? Along with these questions, students received a list of materials available for the experiment. In the classroom, they proposed two protocols of eight 30-m sprints at maximum speed, one protocol with pauses of 120 s and the other protocol with pauses of 20 s between sprints. Their performances were analyzed through the velocity registered by photocells. Blood lactate was analyzed before the first sprint and after the eighth sprint. Blood uric acid was analyzed before exercise and 15 and 60 min after exercises. When discussing the data, students concluded that phosphocreatine restoration is time dependent, and this fact influenced the steady level of performance in the protocol with pauses of 120 s compared with the performance decrease noted in the protocol with pauses of 20 s. As the blood lactate levels showed similar absolute increases after both exercises, the students concluded that lactate production is not related to the performance decrement. This activity allows students to integrate the understanding of muscular energy pathways and to reconsider a controversial concept with facts that challenge the universality of the hypothesis relating lactate production to muscular fatigue.

    The purpose of this study was to examine the effect of lifestyle intervention on the development of fatigue, nutritional status and quality of life of patients with gynecologic cancer. A nonequivalent control group quasi-experimental design was used. Participants were 49 patients with gynecologic cancer. They were assigned to the experiment group (n=24) or the control group (n=25). The lifestyle intervention for this study consisted of physical activity, nutritional education, telephone call counseling, health counseling, monitoring for lifestyle, and affective support based on Cox's Interaction Model of Client Health Behavior and was implemented for six weeks. Significant group differences were found for fatigue (p =.037), nutritional status (p =.034) and social/family well-being (p =.035) in these patients with gynecologic cancer. Results indicate that this lifestyle intervention is effective in lessening fatigue, and improving nutritional status and social/family well-being. Therefore, nurses in hospitals should develop strategies to expand and provide lifestyle interventions for patients with cancer.

  9. Multiaxial Cycle Deformation and Low-Cycle Fatigue Behavior of Mild Carbon Steel and Related Welded-Metal Specimen

    Full Text Available The low-cycle fatigue experiments of mild carbon Q235B steel and its related welded-metal specimens are performed under uniaxial, in-phase, and 90° out-of-phase loading conditions. Significant additional cyclic hardening for 90° out-of-phase loading conditions is observed for both base metal and its related weldment. Besides, welding process produces extra additional hardening under the same loading conditions compared with the base metal. Multiaxial low-cycle fatigue strength under 90° out-of-phase loading conditions is significantly reduced for both base-metal and welded-metal specimens. The weldment has lower fatigue life than the base metal under the given loading conditions, and the fatigue life reduction of weldment increases with the increasing strain amplitude. The KBM, FS, and MKBM critical plane parameters are evaluated for the fatigue data obtained. The FS and MKBM parameters are found to show better correlation with fatigue lives for both base-metal and welded-metal specimens.

    Experience sampling studies on Big Five-related behavior show that people display the whole spectrum of each trait in their daily behavior, and that desirable Big Five states-especially state Extraversion-are related to positive mood. However, other research lines suggest that extraverted and conscientious behavior may be mentally depleting. The present research examined this possibility by extending the time frame of the measured personality processes. A 12-day experience sampling study (N = 48; observations = 2,328) measured Big Five states, mood, stress, and fatigue five times a day. Extraverted and conscientious behavior were concurrently related to positive mood and lower fatigue, but to higher fatigue after a 3-hour delay. These relations were not moderated by personality traits. The relation between extraverted behavior and delayed fatigue was mediated by the number of people the person had encountered. Whether the person had a goal mediated the relation between conscientious behavior and delayed fatigue. Extraverted and conscientious behavior predict mental depletion after a 3-hour delay. The results help reconcile previous findings regarding the consequences of state Extraversion and provide novel information about the consequences of state Conscientiousness. © 2016 Wiley Periodicals, Inc.

    We determined the extent and distribution of cancers in relatives of 379 children newly diagnosed with cancer. Family history was collected from 1,337 first-degree and 3,399 second-degree relatives and incidence compared with national age- and gender-specific rates. Overall, 14 children (3.7%) had a relative with a history of childhood cancer and 26 children (6.9%) had a first-degree relative with a history of cancer, with only one of these having an identifiable familial cancer syndrome. There was a higher than expected incidence of childhood cancer among first-degree relatives (parents and siblings) (standardized incidence ratio (SIR) 1.43; 95% CI 0.54-5.08). There was also a higher than expected incidence of adult cancers among first-degree relatives (SIR 1.45; 95% CI 0.93-2.21), particularly in females (SIR 1.82; 95% CI 1.26-3.39). The increased family cancer history in first-degree females was largely attributable to an effect in mothers (SIR 1.78; 95% CI 1.27-3.33). The gender-specific association was reflected in higher than expected incidence rates of breast cancer in both mothers (SIR 1.92; 95% CI 0.72-6.83) and aunts (SIR 1.64; 95% CI 0.98-2.94). These findings support the hypothesis that previously undetected familial cancer syndromes contribute to childhood cancer.

    Recent findings by Verdonk et al. show that the prevalence of work-related fatigue among 47,000 Dutch employees is greatest in highly-educated women, aged 50-64 years. Although the study has several limitations, the findings are alarming, demand urgent measures and should be on the shortlist of policy makers, employers, and company doctors. Reduced time pressure and emotional demand at work, adequate support for women's ambitions, and proper consideration for the work-private life balance are needed. Coaching may help women to become more assertive and generate more job control. In addition, the problem of workplace violence must be adequately addressed. I am of the strong opinion that work-related fatigue in women would significantly decrease if women were to occupy more leadership positions and top jobs. In such positions they would have greater autonomy and more opportunities to organise their work according to their own time schedules and insights. The time is ripe for women to be given a quota of top positions in the Netherlands.

    Physical activity (PA) improves fatigue and quality of life (QOL) in cancer survivors. Our aim was to assess whether a 2-month PA intervention improves fatigue and QOL for people with advanced lung cancer. Participants with advanced lung cancer, Eastern Cooperative Oncology Group performance status (PS) ≤2, >6 months life expectancy, and ability to complete six-min walk test, were stratified (disease stage, PS 0-1 versus 2, centre) and randomized (1:1) in an open-label study to usual care (UC) (nutrition and PA education materials) or experimental intervention (EX): UC plus 2-month supervised weekly PA and behaviour change sessions. Assessments occurred at baseline, 2, 4, and 6 months. The primary endpoint was fatigue [Functional Assessment of Cancer Therapy-Fatigue (FACT-F) questionnaire] at 2 months. The study was designed to detect a difference in mean FACT-F subscale score of 6. Analysis was intention-to-treat using linear mixed models. We recruited 112 patients: 56 (50.4%) were randomized to EX, 55(49.5%) to UC; 1 ineligible. Male 55%; median age 64 years (34-80); 106 (96%) non-small cell lung cancer; 106 (95.5%) stage IV. At 2, 4 and 6 months, 90, 73 and 62 participants were assessed, respectively, with no difference in attrition between groups. There were no significant differences in fatigue between the groups at 2, 4 or 6 months: mean scores at 2 months EX 37.5, UC 36.4 (difference 1.2, 95% CI - 3.5, 5.8, P = 0.62). There were no significant differences in QOL, symptoms, physical or functional status, or survival. Adherence to the intervention was good but the intervention group did not increase their PA enough compared to the control group, and no difference was seen in fatigue or QOL.

    Physical exercise mitigates fatigue during androgen deprivation therapy (ADT); however, the effects of different exercise prescriptions are unknown. To determine the long-term effects of different exercise modes on fatigue in prostate cancer patients undergoing ADT. Between 2009 and 2012, 163 prostate cancer patients aged 43-90 y on ADT were randomised to exercise targeting the musculoskeletal system (impact loading+resistance training; ILRT; n=58), the cardiovascular and muscular systems (aerobic+resistance training; ART; n=54), or to usual care/delayed exercise (DEL; n=51) for 12 mo across university-affiliated exercise clinics in Australia. Supervised ILRT for 12 mo, supervised ART for 6 mo followed by a 6-mo home program, and DEL received a printed booklet on exercise information for 6 mo followed by 6-mo stationary cycling exercise. Fatigue was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 36 and vitality using the Short Form-36. Analysis of variance was used to compare outcomes for groups at 6 mo and 12 mo. Fatigue was reduced (p=0.005) in ILRT at 6 mo and 12 mo (∼5 points), and in ART (p=0.005) and DEL (p=0.022) at 12 mo. Similarly, vitality increased for all groups (p≤0.001) at 12 mo (∼4 points). Those with the highest levels of fatigue and lowest vitality improved the most with exercise (p trend fatigue and enhancing vitality during ADT. Patients with the highest levels of fatigue and lowest vitality had the greatest benefits. We compared the effects of different exercise modes on fatigue in men on androgen deprivation therapy. All exercise programs reduced fatigue and enhanced vitality. We conclude that undertaking some form of exercise will help reduce fatigue, especially in those who are the most fatigued.

    Fatigue and physical inactivity, critical problems facing cancer survivors, impact overall health and functioning. Our group designed a novel methodology to evaluate the temporal, dynamic patterns in real-world settings. Using real-time technology, the temporal, dynamic relationship between real-time fatigue and free-living is described and compared in cancer survivors who were treated with hematopoietic stem cell transplantation (n = 25) and age- and gender-matched healthy controls (n = 25). Subjects wore wrist actigraphs on their nondominant hand to assess free-living physical activity, measured in 1-minute epochs, over 7 days. Subjects entered real-time fatigue assessments directly into the subjective event marker of the actigraph 5 times per day. Running averages of mean 1-minute activity counts 30, 60, and 120 minutes before and after each real-time fatigue score were correlated with real-time fatigue using generalized estimating equations, RESULTS:: A strong inverse relationship exists between real-time fatigue and subsequent free-living physical activity. This inverse relationship suggests that increasing real-time fatigue limits subsequent physical activity (B range= -0.002 to -0.004; P < .001). No significant differences in the dynamic patterns of real-time fatigue and free-living physical activity were found between groups. To our knowledge, this is the first study to document the temporal and potentially causal relationship between real-time fatigue and free-living physical activity in real-world setting. These findings suggest that fatigue drives the subsequent physical activity and the relationship may not be bidirectional. Understanding the temporal, dynamic relationship may have important health implications for developing interventions to address fatigue in cancer survivors.

    The laser powder bed fusion (L-PBF) technique builds parts with higher static strength than the conventional manufacturing processes through the formation of ultrafine grains. However, its fatigue endurance strength σ f does not match the increased monotonic tensile strength σ b. This work examines the monotonic and fatigue properties of as-built and heat-treated L-PBF stainless steel 316L. It was found that the general linear relation σ f = mσ b for describing conventional ferrous materials is not applicable to L-PBF parts because of the influence of porosity. Instead, the ductility parameter correlated linearly with fatigue strength and was proposed as the new fatigue assessment criterion for porous L-PBF parts. Annealed parts conformed to the strength-ductility trade-off. Fatigue resistance was reduced at short lives, but the effect was partially offset by the higher ductility such that comparing with an as-built part of equivalent monotonic strength, the heat-treated parts were more fatigue resistant.

    Background Response shift has gained increasing attention in the measurement of health-related quality of life (QoL) as it may explain counter-intuitive findings as a result of adaptation to deteriorating health. Objective To search for response shift type explanations to account for counter-intuitive findings in QoL measurement. Methods Qualitative investigation of the response behaviour of small-cell lung cancer (SCLC) patients (n = 23) in the measurement of fatigue with The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) question ‘were you tired’. Interviews were conducted at four points during 1st line chemotherapy: at the start of chemotherapy, 4 weeks later, at the end of chemotherapy, and 6 weeks later. Patients were asked to ‘think aloud’ when filling in the questionnaire. Results Fifteen patients showed discrepancies between their answer to the EORTC question ‘were you tired’ and their level of fatigue spontaneously reported during the interview. These patients chose the response options ‘not at all’ or ‘a little’ and explained their answers in various ways. In patients with and without discrepancies, we found indications of recalibration response shift (e.g. using a different comparison standard over time) and of change in perspective (e.g. change towards a more optimistic perspective). Patients in the discrepancy group reported spontaneously how they dealt with diagnosis and treatment, i.e. by adopting protective and assertive behaviour and by fighting the stigma. They distanced themselves from the image of the stereotypical cancer patient and presented themselves as not suffering and accepting fatigue as consequence of treatment. Conclusion In addition to response shift, this study suggests that ‘self-presentation’ might be an important mechanism affecting QoL measurement, particularly during phases when a new equilibrium needs to be found.

  18. Relation Between Residual and Hoop Stresses and Rolling Bearing Fatigue Life

    2015-01-01

    Rolling-element bearings operated at high speed or high vibration may require a tight interference fit between the bore of the bearing and shaft to prevent rotation of the bearing bore around the shaft and fretting damage at the interfaces. Previous work showed that the hoop stresses resulting from tight interference fits can reduce bearing lives by as much as 65 percent. Where tight interference fits are required, case-carburized steel such as AISI 9310 or M50 NiL is often used because the compressive residual stresses inhibit subsurface crack formation and the ductile core inhibits inner-ring fracture. The presence of compressive residual stress and its combination with hoop stress also modifies the Hertz stress-life relation. This paper analyzes the beneficial effect of residual stresses on rolling-element bearing fatigue life in the presence of high hoop stresses for three bearing steels. These additional stresses were superimposed on Hertzian principal stresses to calculate the inner-race maximum shearing stress and the resulting fatigue life of the bearing. The load-life exponent p and Hertz stress-life exponent n increase in the presence of compressive residual stress, which yields increased life, particularly at lower stress levels. The Zaretsky life equation is described and is shown to predict longer bearing lives and greater load- and stress-life exponents, which better predicts observed life of bearings made from vacuum-processed steel.

    2014-07-01

    To determine if differences in objective measures of laryngeal function can meaningfully explain different levels of self-perceptions of effort or fatigue in patients with vocal fold paresis. A retrospective chart review of 72 patients with vocal fold paresis diagnosed using laryngeal electromyography, who had either been observed (n=21), treated only by injection (n=24), or treated only by surgery (n=27). Before and after treatment/observation, patients' subjective ratings of severity of vocal effort and fatigue were assessed using the Glottal Function Index. Laryngeal function was assessed using maximum phonation time and translaryngeal flow. None of the variables demonstrated a significant linear change across time. Post hoc Tukey analyses following analysis of variance (ANOVA) found significant differences in flow among three groups, those rating symptoms of effort as no problem, moderate problem, or severe problem. Post hoc Tukey analyses following ANOVA found significant differences in the amount that flow changed among three groups, those demonstrating no difference, minor differences, or major differences in ratings of effort before and after treatment. Changes in reported symptom severity of effort were related to changes in translaryngeal midvowel flow that were not explained by passage of time. 4. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

    Triathlon competition is dependent on the athletes' ability to perform each discipline at optimal time, without excessive fatigue influencing the next one. Determine the effects of a long distance triathlon on biochemistry parameters related to liver function. Blood samples from six athletes were collected before (T = 0) and immediately after the triathlon competition (T = 1). AST, ALT and alkaline phosphatase (ALP) values were assessed. Significant changes after triathlon competition were found for AST and ALP and no significant changes were found for ALT over time. A series of metabolically alterations, mainly related to energy production and also to muscle and skeletal adaptations occurs during and after strenuous exercise. The altered status of those metabolical changes cannot directly reflect the intensity of any possible muscular or hepatic damage or overload and elevated AST/ALT ratio is better associated to skeletal muscle lesion during competition.

    To investigate whether aerobic capacity explains the level of self-reported physical activity, physical functioning, and participation and autonomy in daily living in persons with multiple sclerosis-related fatigue. A cross-sectional study. Sixty-two participants with multiple sclerosis-related fatigue. Aerobic capacity was measured with a leg ergometer and was expressed as maximal oxygen uptake (VO2max, in ml/kg/min). Physical activity was measured with the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD), physical functioning with the Short Form 36 - physical functioning (SF36-pf), and participation and autonomy in daily living with the Impact on Participation and Autonomy questionnaire (IPA). Multiple regression analyses were performed, adjusted for potential confounders (gender, age, body mass index, educational level, and employment status). Mean maximal oxygen uptake (VO2max) was 23.9 ml/kg/min (standard deviation (SD) 6.3 ml/kg/min). There was no significant relationship between VO2max and physical activity (PASIPD): β = 0.320, 95% confidence interval (95% CI) = -0.109 to 0.749, R2 = 10.8%. Higher VO2max correlated with better physical functioning (SF36-pf): β = 1.527, 95% CI = 0.820-2.234, R2 = 25.9%, and was significantly related to IPA domains "autonomy indoors" (β = -0.043, 95% CI = -0.067 to -0.020, R2 = 20.6%), "autonomy outdoors" (β = -0.037, 95% CI = -0.062 to -0.012, R2 = 18.2%) and "social life and relationships" (β=-0.033, 95% CI = -0.060 to -0.007, R2 = 21.3%). Maximum aerobic capacity was severely reduced in persons with multiple sclerosis-related fatigue. This partly explains the limited physical functioning and restrictions in participation and autonomy indoors, outdoors and in social life and relationships in these persons.

    During senescence, despite the loss of strength (force-generating capability) associated with sarcopenia, muscle endurance may improve for isometric contractions. The purpose of this study was to perform a systematic meta-analysis of young versus older adults, considering likely moderators (ie, contraction type, joint, sex, activity level, and task intensity). A 2-stage systematic review identified potential studies from PubMed, CINAHL, PEDro, EBSCOhost: ERIC, EBSCOhost: Sportdiscus, and The Cochrane Library. Studies reporting fatigue tasks (voluntary activation) performed at a relative intensity in both young (18-45 years of age) and old (≥ 55 years of age) adults who were healthy were considered. Sample size, mean and variance outcome data (ie, fatigue index or endurance time), joint, contraction type, task intensity (percentage of maximum), sex, and activity levels were extracted. Effect sizes were (1) computed for all data points; (2) subgrouped by contraction type, sex, joint or muscle group, intensity, or activity level; and (3) further subgrouped between contraction type and the remaining moderators. Out of 3,457 potential studies, 46 publications (with 78 distinct effect size data points) met all inclusion criteria. A lack of available data limited subgroup analyses (ie, sex, intensity, joint), as did a disproportionate spread of data (most intensities ≥ 50% of maximum voluntary contraction). Overall, older adults were able to sustain relative-intensity tasks significantly longer or with less force decay than younger adults (effect size=0.49). However, this age-related difference was present only for sustained and intermittent isometric contractions, whereas this age-related advantage was lost for dynamic tasks. When controlling for contraction type, the additional modifiers played minor roles. Identifying muscle endurance capabilities in the older adult may provide an avenue to improve functional capabilities, despite a clearly established decrement in

    The effects of mental fatigue on the availability of cognitive resources and associated response-related processes were examined using event-related brain potentials. Subjects performed a Go/NoGo task for 60 min. Reaction time, number of errors, and mental fatigue scores all significantly increased with time spent on the task. The NoGo-P3 amplitude significantly decreased with time on task, but the Go-P3 amplitude was not modulated. The amplitude of error-related negativity (Ne/ERN) also decreased with time on task. These results indicate that mental fatigue attenuates resource allocation and error monitoring for NoGo stimuli. The Go- and NoGo-P3 latencies both increased with time on task, indicative of a delay in stimulus evaluation time due to mental fatigue. NoGo-N2 latency increased with time on task, but NoGo-N2 amplitude was not modulated. The amplitude of response-locked lateralized readiness potential (LRP) significantly decreased with time on task. Mental fatigue appears to slows down the time course of response inhibition, and impairs the intensity of response execution.

    Psychosocial factors, musculoskeletal disorders and work-related fatigue have adverse effects on individual nurses and place a substantial financial burden on health care. Evidence of an association has been reported in the literature, but no theoretical explanation has been published to date. To explore and develop a structural model to provide a theoretical explanation for this relationship. A cross-sectional study using data from 201 valid samples of emergency and critical care nurses across public hospitals in Brunei was performed via self-administered questionnaire. The structural equation model was assessed using partial least squares analysis. A valid and robust structural model was constructed. This revealed that 61.5% of the variance in chronic fatigue could be explained by psychosocial factors and musculoskeletal disorders pathways. Among the psychosocial factors, work-family conflict was identified as a key mediator for progression of musculoskeletal problems and subsequent fatigue through stress and burnout. This report provides a novel theoretical contribution to understanding the relationship between psychosocial factors, musculoskeletal disorders and work-related fatigue. These preliminary results may be useful for future studies on the development of work-related fatigue and musculoskeletal disorders, particularly the central role of work-family conflict.

    (1) To assess real-time patterns of fatigue; (2) to assess the association between a real-time fatigue score and 3 commonly used questionnaires (Checklist Individual Strength [CIS] fatigue subscale, Modified Fatigue Impact Scale (MFIS), and Fatigue Severity Scale [FSS]); and (3) to establish factors that confound the association between the real-time fatigue score and the conventional fatigue questionnaires in patients with multiple sclerosis (MS). Cross-sectional study. MS-specialized outpatient facility. Ambulant patients with MS (N=165) experiencing severe self-reported fatigue. Not applicable. A real-time fatigue score was assessed by sending participants 4 text messages on a particular day (How fatigued do you feel at this moment?; score range, 0-10). Latent class growth mixed modeling was used to determine diurnal patterns of fatigue. Regression analyses were used to assess the association between the mean real-time fatigue score and the CIS fatigue subscale, MFIS, and FSS. Significant associations were tested for candidate confounders (eg, disease severity, work status, sleepiness). Four significantly different fatigue profiles were identified by the real-time fatigue score, namely a stable high (n=79), increasing (n=57), stable low (n=16), and decreasing (n=13). The conventional questionnaires correlated poorly (rquestionnaires, ranging from 15.4% to 35%. Perceived fatigue showed 4 different diurnal patterns in patients with MS. Severity of sleepiness is an important confounder to take into account in the assessment of fatigue. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

    To gain insight into fatigued workers' perspectives regarding work experience before and after receiving vocational rehabilitation (VR) treatments. A qualitative survey was conducted using semi-structured interviews with 21 fatigued workers who attended an outpatient multi-component VR treatment. Six months after treatment, work-related limitations and employed VR strategies at work before treatment were explored. Next, VR treatment experiences regarding return-to-work (RTW) were explored. Two researchers performed partially independent, qualitative analyses that revealed topics, discussed by the project team, and organised into domains, categories and sub-categories. Work-related limitations were: symptoms of prolonged fatigue, personal limitations (e.g. lack of self-reflection on individual capacity and limitations), interpersonal factors, activities and conditions at work and life/work imbalance. Before the treatment, VR strategies such as work adaptations, well-intentioned advice and support, and/or referral to psychological or physical care were employed. VR treatment experiences on RTW were: personal challenges (e.g. gained awareness and coping skills), improved activities during work, work adaptations and unresolved problems (e.g. remaining fatigue symptoms and sickness absence). New information about work experiences before and after multi-component VR treatments in workers with prolonged fatigue may help employers, occupational physicians and other caregivers to develop VR strategies that better meet individuals' needs.

    Ginsenoside Rg3 has shown multiple pharmacological activities and been considered as one of the most promising approaches for fatigue treatment. However, little is known about the cellular and molecular mechanisms of Rg3 on anti-fatigue and the effect of Rg3 on dopaminergic system has not been reported yet. The major aim of this study is to investigate the effect of Rg3 on TH expression and the related biochemical parameters, such as PKAα, ERK1/2, Akt and α-synuclein in brain of fatigue rats. Weight-loaded forced swimming was performed to establish an animal model of fatigue. Rg3 (10mg/kg, 50mg/kg and 100mg/kg) was intragastrically administrated before swimming. The effect of Rg3 on the expression and phosphorylation of TH and TH-related proteins in fatigue rats or in SH-SY5Y cells was assessed with western blotting. HPLC was used to examine the level of DA and DOPAC in the fatigue rats tissues. TH and phosphorylated TH were decreased in different brain regions of which ventral midbrain were less affected in weight-loaded forced swimming rats. Pretreatment with Rg3 significantly suppressed fatigue-induced decrease expression of TH and TH phosphorylation. Also treatment with Rg3 reversed the decrease expression of PKAα as well as the phosphorylation of ERK1/2 and Akt which were induced by weight-loaded forced swimming. Moreover, weight-loaded swimming could induce the increase expression of α-synuclein in hippocampus and midbrain, while suppressed α-synuclein expression in striatum and prefrontal cortex. Furthermore, Rg3 could induce the increase of TH expression and phosphorylation which was accompanied with elevated expression and phosphorylation of related kinase proteins in vitro, while the inhibitors of kinase proteins could suppress these effects of Rg3. In addition, HPLC results showed that Rg3 could reverse the weight-loaded swimming-induced increase of DOPAC/DA ratio. Our data suggest that fatigue can induce the decrease of DA which might partially

    One hallmark of chronic fatigue syndrome (ME/CFS) is task related worsening of fatigue. Global brain hypoperfusion, abnormal regional activation, and altered functional connectivity of brain areas associated with cognition and memory have been reported but remain controversial. We enrolled 17 female participants fulfilling the CDC Criteria for ME/CFS and 16 matched healthy controls (HC). Using a 3T-Phillips Achieva MRI-scanner, pseudo-continuous arterial spin-labeling (pCASL), was used to study the dynamics of regional cerebral blood flow (rCBF) and their relationship to mental fatigue in ME/CFS patients and HC during a demanding cognitive task, i.e. modified Paced-Auditory-Serial-Addition-Testing (PASAT). ME/CFS subjects reported more fatigue than HC at baseline (p fatigue in ME/CFS participants and HC. Although not different between groups, overall CBF significantly increased over the first 3 min of the PASAT and then decreased thereafter. Regional CBF (rCBF) changes were significantly different between groups during the post-task recovery period. Whereas improvement of fatigue of ME/CFS subjects was associated with decreased rCBF in both superior temporal gyri (STG), precuneus, and fusiform gyrus, it was associated with increased rCBF in the same areas in HC. Our results suggest that ME/CFS is associated with normal global CBF at rest and during a strenuous task (PASAT); however rCBF of several brain regions associated with memory, goal-oriented attention, and visual function was differentially associated with recovery from fatigue in ME/CFS patients and HC.

    There is consistent scientific evidence that professional drivers constitute an occupational group that is highly exposed to work related stressors. Furthermore, several recent studies associate work stress and fatigue with unsafe and counterproductive work behaviors. This study examines the association between stress-related work conditions of Bus Rapid Transport (BRT) drivers and risky driving behaviors; and examines whether fatigue is a mechanism that mediates the association between the two. A sample of 524 male Bus Rapid Transit (BRT) operators were drawn from four transport companies in Bogotá, Colombia. The participants answered a survey which included an adapted version of the Driver Behavior Questionnaire (DBQ) for BRT operators, as well as the Effort-Reward Imbalance and Job Content Questionnaires, the Subjective Fatigue subscale of the Checklist Individual Strength (CIS) and the Need for Recovery after Work Scale (NFR). Utilizing Structural Equation Models (SEM) it was found that risky driving behaviors in BRT operators could be predicted through job strain, effort-reward imbalance and social support at work. It was also found that fatigue and need for recovery fully mediate the associations between job strain and risky driving, and between social support and risky driving, but not the association between effort/reward imbalance (ERI) and risky driving. The results of this study suggest that a) stress related working conditions (Job Strain, Social Support and ERI) are relevant predictors of risky driving in BRT operators, and b) that fatigue is the mechanism which links another kind of stress related to working conditions (job strain and low social support) with risky driving. The mechanism by which ERI increases risky driving in BRT operators remains unexplained. This research suggests that in addition to the individual centered stress-reduction occupational programs, fatigue management interventions aimed to changing some working conditions may reduce

    Full Text Available Familial risks of lung cancer are well-established, but whether lung cancer clusters with other discordant cancers is less certain, particularly beyond smoking-related sites, which may provide evidence on genetic contributions to lung cancer aetiology. We used a novel approach to search for familial associations in the Swedish Family-Cancer Database. This involved assessment of familial relative risk for cancer X in families with increasing numbers of lung cancer patients and, conversely, relative risks for lung cancer in families with increasing numbers of patients with cancers X. However, we lacked information on smoking. The total number of lung cancers in the database was 125 563. We applied stringent statistical criteria and found that seven discordant cancers were associated with lung cancer among family members, and six of these were known to be connected with smoking: oesophageal, upper aerodigestive tract, liver, cervical, kidney and urinary bladder cancers. A further novel finding was that cancer of unknown primary also associated with lung cancer. We also factored in histological evidence and found that anal and connective tissue cancers could be associated with lung cancer for reasons other than smoking. For endometrial and prostate cancers, suggestive negative associations with lung cancer were found. Although we lacked information on smoking it is prudent to conclude that practically all observed discordant associations of lung cancer were with cancers for which smoking is a risk factor.

    The relationship between fatigue impact and walking capacity and perceived ability in patients with multiple sclerosis (MS) is inconclusive in the existing literature. A better understanding might guide new treatment avenues for fatigue and/or walking capacity in patients with MS. To investigate the relationship between the subjective impact of fatigue and objective walking capacity as well as subjective walking ability in MS patients. A cross-sectional multicenter study design was applied. Ambulatory MS patients (n = 189, age: 47.6 ± 10.5 years; gender: 115/74 women/men; Expanded Disability Status Scale (EDSS): 4.1 ± 1.8 [range: 0-6.5]) were tested at 11 sites. Objective tests of walking capacity included short walking tests (Timed 25-Foot Walk (T25FW), 10-Metre Walk Test (10mWT) at usual and fastest speed and the timed up and go (TUG)), and long walking tests (2- and 6-Minute Walk Tests (MWT). Subjective walking ability was tested applying the Multiple Sclerosis Walking Scale-12 (MSWS-12). Fatigue impact was measured by the self-reported modified fatigue impact scale (MFIS) consisting of a total score (MFIS total ) and three subscales (MFIS physical , MFIS cognitive and MFIS psychosocial ). Uni- and multivariate regression analysis were performed to evaluate the relation between walking and fatigue impact. MFIS total was negatively related with long (6MWT, r = -0.14, p = 0.05) and short composite (TUG, r = -0.22, p = 0.003) walking measures. MFIS physical showed a significant albeit weak relationship to walking speed in all walking capacity tests (r = -0.22 to -0.33, p < .0001), which persisted in the multivariate linear regression analysis. Subjective walking ability (MSWS-12) was related to MFIS total (r = 0.49, p < 0.0001), as well as to all other subscales of MFIS (r = 0.24-0.63, p < 0.001), showing stronger relationships than objective measures of walking. The physical impact of fatigue is weakly

    2016-09-01

    Chronic stress and its subsequent effects on biological stress systems have long been recognized as predisposing and perpetuating factors in chronic fatigue, although the exact mechanisms are far from being completely understood. In this review, we propose that sensitivity of immune cells to glucocorticoids (GCs) and catecholamines (CATs) may be the missing link in elucidating how stress turns into chronic fatigue. We searched for in vitro studies investigating the impact of GCs or CATs on mitogen-stimulated immune cells in chronically stressed or fatigued populations, with 34 original studies fulfilling our inclusion criteria. Besides mixed cross-sectional findings for stress- and fatigue-related changes of GC sensitivity under basal conditions or acute stress, longitudinal studies indicate a decrease with ongoing stress. Research on CATs is still scarce, but initial findings point towards a reduction of CAT sensitivity under chronic stress. In the long run, resistance of immune cells to stress signals under conditions of chronic stress might translate into self-maintaining inflammation and inflammatory disinhibition under acute stress, which in turn lead to fatigue.

    2017-04-01

    The term fatigue is used to describe a distressing and persistent symptom of physical and/or mental tiredness in certain clinical populations, with distinct but ultimately complex, multifactorial and heterogenous pathophysiology. Chronic fatigue impacts on quality of life, reduces the capacity to perform activities of daily living, and is typically measured using subjective self-report tools. Fatigue also refers to an acute reduction in the ability to produce maximal force or power due to exercise. The classical measurement of exercise-induced fatigue involves neuromuscular assessments before and after a fatiguing task. The limitations and alternatives to this approach are reviewed in this paper in relation to the lower limb and whole-body exercise, given the functional relevance to locomotion, rehabilitation and activities of daily living. It is suggested that under some circumstances, alterations in the central and/or peripheral mechanisms of fatigue during exercise may be related to the sensations of chronic fatigue. As such, the neurophysiological correlates of exercise-induced fatigue are briefly examined in two clinical examples where chronic fatigue is common: cancer survivors and people with multiple sclerosis. This review highlights the relationship between objective measures of fatigability with whole-body exercise and perceptions of fatigue as a priority for future research, given the importance of exercise in relieving symptoms of chronic fatigue and/or overall disease management. As chronic fatigue is likely to be specific to the individual and unlikely to be due to a simple biological or psychosocial explanation, tailored exercise programmes are a potential target for therapeutic intervention.

    Full Text Available OBJECTIVE: To examine the relationship between fatigue and temperament-character inventory among patients with Multiple Sclerosis (MS. METHODS: This study was conducted at a tertiary referral center between August-December 2010. Overall 75 patients with MS and 75 healthy volunteers in the control group were included into study. Patients with MS and controls were divided into two groups as ‘’Fatigue’’ and ‘’non-Fatigue’’. The personal features of patients and controls were determined using the ‘‘Temperament-Character Inventory’’. Fatigue individuals were detected using the ‘‘Fatigue Severity Scale’’. Statistical analyses were done by SPSS 16.0 software. RESULTS: In the study, ‘‘Harm Avoidance’’ and “Impulsiveness” were high, but ‘‘Social Acceptance’’ was low, among MS patients. Namely, fatigue patients with MS are more reluctant, passive, distrustful, easily fatigue, pessimistic, avoiding from harmful conditions and intolerant individuals than non-fatigue patients with MS and controls. Patients with MS were found more fatigue than healthy individuals although they were not entered to the ‘’fatigue classification’’ according to FSS. ‘‘Persistence’’ and ‘‘Purposefulness’’ scores were low among MS patients. Namely, fatigue patients with MS are more indolent, inactive, hesitant, irregular, rarely working for high success, tend to easily renunciation, and purposeless individuals than healthy volunteers. CONCLUSION: Fatigue significantly affects the temperament and character features in patients with Multiple Sclerosis

    Cognitive impairment has frequently been shown in patients who seek medical care for stress-related mental health problems. This study aims to extend the current knowledge of cognitive impairments in these patients by focusing on perceived fatigue and effects of distraction during cognitive testing. Executive function and attention were tested in a group of patients with stress-related exhaustion (n = 25) and compared with healthy controls (n = 25). Perceived fatigue was measured before, during and after the test session, and some of the tests were administered with and without standardized auditory distraction. Executive function and complex attention performance were poorer among the patients compared to controls. Interestingly, their performance was not significantly affected by auditory distraction but, in contrast to the controls, they reported a clear-cut increase in mental tiredness, during and after the test session. Thus, patients with stress-related exhaustion manage to perform during distraction but this was achieved at a great cost. These findings are discussed in terms of a possible tendency to adopt a high-effort approach despite cognitive impairments and the likelihood that such an approach will require increased levels of effort, which can result in increased fatigue. We tentatively conclude that increased fatigue during cognitive tasks is a challenge for patients with stress-related exhaustion and plausibly of major importance when returning to work demanding high cognitive performance.

    Local muscle fatigue may be related to potassium efflux from the muscle cell and/or lactate accumulation within the muscle. Local fatigue causes a decrease in median frequency (MPF) of the electromyogram's power spectrum during isometric contractions but its relationship to changes in potassium and lactate during dynamic exercise is equivocal. Thus, this investigation evaluated relationships between changes in the MPF from the vastus lateralis and blood levels of lactate and potassium during an incremental cycling test and recovery. Trained cyclists (n=8) completed a discontinuous, graded cycle test to exhaustion under normal and glycogen-reduced conditions. The glycogen reduced condition promoted an environment of lower lactate production while permitting a consistent potassium response. Blood samples and maximal isometric EMG data were collected at the end of each stage and during recovery. Maximal lactate levels were ∼ 60% lower in the glycogen reduced condition; potassium was similar between trials. MPF did not change significantly at volitional fatigue. Further, MPF was not significantly related to lactate (p>0.27) or potassium (p>0.16) in either condition. Though both lactate and potassium have been implicated as factors relating to local muscle fatigue, neither is significantly related to changes in MPF during or after progressive exercise on a cycle ergometer.

    Many breast cancer survivors report cancer and cancer treatment-associated cognitive change. However, very little is known about the relationship between physical activity and subjective memory impairment (SMI) in this population. The purpose of this study is to examine the relationship between physical activity and SMI and longitudinally test a model examining the role of self-efficacy, fatigue and distress as potential mediators. Post-treatment breast cancer survivors (N = 1477) completed measures of physical activity, self-efficacy, distress (depression, concerns about recurrence, perceived stress, anxiety), fatigue and SMI at baseline and 6-month follow-up. A subsample (n = 362) was randomly selected to wear an accelerometer. It was hypothesized that physical activity indirectly influences SMI via exercise self-efficacy, distress and fatigue. Relationships were examined using panel analysis within a covariance modeling framework. The hypothesized model provided a good fit in the full sample (χ 2  = 1462.5, df = 469, p = exercise self-efficacy and reduced distress and fatigue. Higher levels of physical activity, lower levels of fatigue and distress and higher exercise self-efficacy may play an important role in understanding SMI in breast cancer survivors across time. Future research is warranted to replicate and explore these relationships further. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    To investigate the employment status of lung cancer survivors and the work-related problems they face. Although the number of lung cancer survivors is increasing, little is known about their employment and work-related issues. We enrolled 830 lung cancer survivors 12 months after lung cancer curative surgery (median time after diagnosis, 4.11 years) and 1000 volunteers from the general population. All participants completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Core 30-item and a questionnaire that included items relating to their jobs. We used logistic regression analysis to identify independent predictors of unemployment. The employment rate of lung cancer survivors decreased from 68.6% at the time of diagnosis to 38.8% after treatment, which was significantly lower than the employment rate of the general population (63.5%; adjusted odds ratio = 2.31, 95% confidence interval: 1.66-3.22). The posttreatment unemployment rate was higher for women than for men. Among survivors, employment was inversely associated with older age, household income, number of comorbidities, and poor social functioning. Fatigue (78.6%) was the most common work-related problem reported by survivors. Lung cancer survivors experienced more difficulties in employment than did the general population. Age, monthly household income, number of comorbidities, and social functioning appear to be important factors influencing employment status. These findings suggest that lung cancer survivors need support to cope with the financial impact of cancer.

    Physical activity improves the quality of life of cancer survivors, but whether there is a difference between individual vs. group physical activity is unknown. To compare fatigue at 12 weeks in breast cancer survivors after participation in a program of group vs. individual video-assisted physical activity. This was a randomized phase II pilot study carried out in breast cancer survivors at a tertiary breast cancer center. Eligible patients were randomized to individual or group 12-week physical activity program. The primary outcome was fatigue (FACT-F). Aerobic capacity (6-min walk test), muscular strength, and quality-of-life (FACT-G and FACT-B) were assessed. Because of poor accrual, 200 consecutive breast cancer patients were surveyed about their physical activity habits to assess reasons for low recruitment. For all participants (n = 26; n = 12 for group vs. n = 14 for individual), there were some improvement in FACT-F, FACT-G, FACT-B, physical activity level, aerobic capacity, and shoulder strength. Among the 200 patients surveyed, 58% were interested to increase their physical activity level, 15% declared that they were already exercising enough, 9% declared being unable to, 3% declared having no time, and 2% declared having no interest, and other reasons (13%). Among the 200 patients surveyed, 25% preferred in group, 57% preferred alone, and 18% had no preference. Low recruitment precluded conclusions about the efficacy of physical activity practiced in group vs. individually, but both groups derived a benefit. Low willingness to change exercising habits could be the biggest barrier to physical activity in breast cancer survivors. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Pain, fatigue, depression, and sleep disturbance are common in patients with cancer and usually co-occur as a symptom cluster. However, the mechanism underlying this symptom cluster is unclear. This study aimed to identify subgroups of cluster symptoms, compare demographic and clinical characteristics between subgroups, and examine the associations between inflammatory cytokines and cluster symptoms. Participants were 170 Chinese inpatients with cancer from two tertiary hospitals. Inflammatory markers including interleukin-6 (IL-6), interleukin-1 receptor antagonist, and tumor necrosis factor alpha were measured. Intergroup differences and associations of inflammatory cytokines with the cluster symptoms were examined with one-way analyses of variance and logistic regression. Based on cluster analysis, participants were categorized into Subgroup 1 (all low symptoms), Subgroup 2 (low pain and moderate fatigue), or Subgroup 3 (moderate-to-high on all symptoms). The three subgroups differed significantly in Eastern Cooperative Oncology Group (ECOG) performance status, sex, residence, current treatment, education, economic status, and inflammatory cytokines levels (all P cluster symptoms in cancer patients.

    We studied the mechanism of radiation-induced apoptosis, the factors involved signaling, and the establishment of radiation-resistant cell lines in this study. During the TGF beta-stimulated epithelial mesenchymal transition(EMT), actin rearrangement occurred first and fibronectin matrix assembly followed. These two events were considered independent since cytochalasin-D did not inhibit TGF stimulated matrix assembly and fibronectin supplementation did not induce EMT. During EMT, alpha 5 beta 1 integrin and alpha v integrin have increased but MMP activation was not accompanied, which suggest that induction of extracellular matrix and activation of integrins may be main contributor for the EMT. Serum depriving induced apoptosis of HUVECs was prevented by vascular endothelial growth factor(VEGF) and PMA. The apoptosis prevention by VEGF and PMA were conformed by DNA fragmentation assay. The p53 expression level was down regulated by VEGF and PMA compared with serum deprived HUVECs. However, VEGF and PMA induces c-Myc expression level on these cells. We made the 5 radiation-resistant clones from breast, lung and cervical cancer cells. More than 70%, 100% and 50% increased resistance was detected in breast cancer cells, lung cancer cells, and cervical cells, respectively. We carried out differential display-PCR to clone the radiation-resistant genes. 9 out of 10 genes were analyzed their sequence

    Breast cancer is the cancer most frequently diagnosed in women worldwide. Even though survival rates are continually increasing, breast cancer is often associated with long-term psychological distress, chronic pain, fatigue and impaired quality of life. Yoga comprises advice for an ethical lifestyle, spiritual practice, physical activity, breathing exercises and meditation. It is a complementary therapy that is commonly recommended for breast cancer-related impairments and has been shown to improve physical and mental health in people with different cancer types. To assess effects of yoga on health-related quality of life, mental health and cancer-related symptoms among women with a diagnosis of breast cancer who are receiving active treatment or have completed treatment. We searched the Cochrane Breast Cancer Specialised Register, MEDLINE (via PubMed), Embase, the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 1), Indexing of Indian Medical Journals (IndMED), the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal and Clinicaltrials.gov on 29 January 2016. We also searched reference lists of identified relevant trials or reviews, as well as conference proceedings of the International Congress on Complementary Medicine Research (ICCMR), the European Congress for Integrative Medicine (ECIM) and the American Society of Clinical Oncology (ASCO). We applied no language restrictions. Randomised controlled trials were eligible when they (1) compared yoga interventions versus no therapy or versus any other active therapy in women with a diagnosis of non-metastatic or metastatic breast cancer, and (2) assessed at least one of the primary outcomes on patient-reported instruments, including health-related quality of life, depression, anxiety, fatigue or sleep disturbances. Two review authors independently collected data on methods and results. We expressed outcomes as standardised mean differences (SMDs

    Fatigue is a common symptom of Multiple Sclerosis (MS) that diminishes the quality of life of patients, but its exact mechanism remains poorly understood. There is not a generally adopted scale to determine MS fatigue. Studies that investigated physiopathology of fatigue symptom have shown dysregulation of hypothalamic-pituitaryadrenal (HPA) axis. In the current study, we aimed to compare the results obtained with two separate scales, namely the Fatigue Severity Scale (FSS) and the Neurological Fatigue Index-Multiple Sclerosis (NFI-MS), and assess the relationship between fatigue and serum IL-1β, TNF-α, IL-35, IL-2, IL-10, ACTH, cortisol, α-MSH, β-MSH, γ-MSH and CLIP (Corticotropinlike intermediate lobe peptide) in MS patients categorized as fatigued and non-fatigued on the basis of FSS scores. For the study, a total of 54 (29 females, 25 males) patients diagnosed with RRMS including 26 with fatigue symptom (48.1%), and 26 healthy controls (13 females, 13 males) were enrolled. A FSS score ≥36 was considered as cut-off score to separate fatigued patients from nonfatigued patients. A significant positive correlation was determined between FSS score and NFI-MS scale, NFI-MS 1, NFI-MS 2, NFI-MS 3 and NFI-MS 4 scores. IL-1β, IL-10 and TNF-α levels did not differ between patient and control groups. IL-35 and IL-2 levels were significantly higher among MS patients (pfatigued and nonfatigued patients in the cytokines and HPA parameters studied. ACTH, cortisol and α-MSH were significantly higher in MS group (p=0.02, pfatigue; thus, it may also be widely used to evaluate that symptom. Generally HPA axis is hyperactive in MS patients, but it is not correlated with fatigue in our study. For the first time, levels of CLIP (a type of melanocortin) are studied, and determined to be lower among MS patients. Elevated levels of IL-35 and IL-2 suggest that these cytokines may have a prominent role in MS pathophysiology and can be investigated as potential targets for

    The focus of the study is the analysis of changes in health-related quality of life in various cancer entities during and after an inpatient rehabilitation programme. In a multicentre longitudinal study, a total of 211 cancer patients (breast cancer: N = 84; prostate cancer: N = 90; colon cancer: N = 37) were asked about their quality of life (EORTC QLQ-C30; HADS) at the beginning, the end and 3 months after the end of the rehabilitation programme. In different domains of quality of life significant and mostly clinically relevant improvements were found during rehabilitation. The breast and prostate cancer patients improved most in emotional functioning, colon cancer patients in global quality of life. With regard to the severity of symptoms, the fatigue burden improved in breast and colon cancer patients, nausea in the prostate cancer patients. However, they are increases 3 months after rehabilitation. Functional burdens improved 3 months after the end of rehabilitation in the physical domain for all cancer patients. For breast cancer patients, emotional functioning decreased significantly 3 months after rehabilitation. An inpatient oncological rehabilitation programme can lead to an improvement in quality of life. © 2016 John Wiley & Sons Ltd.

    The objective of this study was to test the efficacy of cognitive-behavioral therapy plus hypnosis (CBTH) to control fatigue in patients with breast cancer undergoing radiotherapy. We hypothesized that patients in the CBTH group receiving radiotherapy would have lower levels of fatigue than patients in an attention control group. Patients (n = 200) were randomly assigned to either the CBTH (n = 100; mean age, 55.59 years) or attention control (n = 100; mean age, 55.97 years) group. Fatigue was measured at four time points (baseline, end of radiotherapy, 4 weeks, and 6 months after radiotherapy). Fatigue was measured using the Functional Assessment of Chronic Illness Therapy (FACIT) -Fatigue subscale and Visual Analog Scales (VASs; Fatigue and Muscle Weakness). The CBTH group had significantly lower levels of fatigue (FACIT) at the end of radiotherapy (z, 6.73; P < .001), 4-week follow-up (z, 6.98; P < .001), and 6-month follow-up (z, 7.99; P < .001) assessments. Fatigue VAS scores were significantly lower in the CBTH group at the end of treatment (z, 5.81; P < .001) and at the 6-month follow-up (z, 4.56; P < .001), but not at the 4-week follow-up (P < .07). Muscle Weakness VAS scores were significantly lower in the CBTH group at the end of treatment (z, 9.30; P < .001) and at the 6-month follow-up (z, 3.10; P < .02), but not at the 4-week follow-up (P < .13). The results support CBTH as an evidence-based intervention to control fatigue in patients undergoing radiotherapy for breast cancer. CBTH is noninvasive, has no adverse effects, and its beneficial effects persist long after the last intervention session. CBTH seems to be a candidate for future dissemination and implementation.

    To prospectively evaluate the prevalence and severity of fatigue and its impact on quality of life (QOL) during and after radical external beam radiotherapy (RT) for prostate cancer. Twenty-eight men with prostate cancer undergoing RT over 6-8 consecutive weeks were prospectively accrued. The Brief Fatigue Inventory (BFI), a validated fatigue assessment tool, was administered at five time points: baseline (week 1), middle of RT (week 3-4), end of RT (last week of RT), and follow-up (median 6.5 weeks after RT). The BFI contained nine questions, each using 0-10 ratings to quantify fatigue severity and interference with six QOL domains. The prevalence of moderate-severe fatigue was plotted as a function of time. Mean sum and subscale scores at each time point were compared to baseline scores using Wilcoxon tests. Linear regression analyses were performed to assess associations between fatigue scores and age, tumor and treatment characteristics. The median age was 69 years (range 57-84), Gleason score 7 (range 6-10), and presenting PSA 9.0 ng/mL (range 2.5 ng/mL-103.0 ng/mL). Patients were treated once daily to a median dose of 74 Gy (range 60 Gy-78 Gy) over a median of 37 fractions (range 30-39). Hormone therapy was used in all patients (median duration 12.2 months). The prevalence of moderate-severe present fatigue increased from 7% at baseline to 8% at mid-RT and 32% at RT completion. Compared to baseline (mean score 11.5), fatigue increased significantly mid-RT (mean score 14.6, p = 0.03) and peaked at the end of RT (mean score 23.5, p = 0.001). Fatigue significantly interfered with walking ability, normal work, daily chores, and enjoyment of life only at the end of RT. After RT completion, fatigue improved but remained higher compared to baseline at 6.5 weeks of follow-up (mean score 15.0, p = 0.02). On linear regression analysis, age, Gleason score, PSA, T-stage, hormone therapy duration, RT dose and fractions were not significantly associated with mean fatigue

    Chronic fatigue (CF) has been reported to be slightly more prevalent in testicular cancer survivors (TCSs) than in the general population. In this study, we wished to explore possible determinants of CF in TCSs median 12 (survey I) and 19 years (survey II) after treatment, in particular the relation to late effects after treatment. Overall, 812 TCSs treated between 1980 and 1994 provided blood samples (testosterone and luteinizing hormone) and completed questionnaires at survey I (1998-2002) and survey II (2007-2008). Hormone levels were categorized according to quartile thresholds for decadal age groups of controls. Associations between CF and possible risk factors, including the Hospital Anxiety and Depression Scale (HADS), treatment, physical activity, hormone levels, neurotoxicity, and comorbidity, were analyzed by logistic regression. Prevalence of CF increased from 15% at survey I to 27% at survey II (P < 0.001). At survey II, risk for CF was increased three- to four-fold for high levels of neuropathy compared with no neuropathy, and two- to three-fold for high levels of Raynaud-like phenomena, and having testosterone levels in the lowest quartile, while being moderately and highly physically active, had a protective effect. Risk for CF in TCSs with higher levels of HADS-Anxiety and HADS-Depression was increased two- to five-fold, respectively. The increasing prevalence of CF in TCSs is a novel finding. Lifestyle interventions, early detection and treatment of depression and anxiety, and possibly testosterone substitution might reduce the risk of CF. Extended long-term follow-up seems to be important. © The Author 2015. Published by Oxford University Press on behalf of the European Society for Medical Oncology. All rights reserved.

    Normal aging results in alterations in the visual, vestibular and somtaosensory systems, which in turn modify the control of balance. Muscle fatigue may exacerbate these age-related changes in sensory and motor functions, and also increase the attentional demands associated with dynamic postural control. The purpose of this study was to investigate the effect of aging on dynamic postural control and posture-related attentional demands before and after a plantar flexor fatigue protocol. Participants (young adults: n = 15; healthy seniors: n = 13) performed a dynamic postural task along the antero-posterior (AP) and the medio-lateral (ML) axes, with and without the addition of a simple reaction time (RT) task. The dynamic postural task consisted in following a moving circle on a computer screen with the representation of the center of pressure (COP). This protocol was repeated before and after a fatigue task where ankle plantar flexor muscles were targeted. The mean COP-target distance and the mean COP velocity were calculated for each trial. Cross-correlation analyses between the COP and target displacements were also performed. RTs were recorded during dual-task trials. Results showed that while young adults adopted an anticipatory control mode to move their COP as close as possible to the target center, seniors adopted a reactive control mode, lagging behind the target center. This resulted in longer COP-target distance and higher COP velocity in the latter group. Concurrently, RT increased more in seniors when switching from static stance to dynamic postural conditions, suggesting potential alterations in the central nervous system (CNS) functions. Finally, plantar flexor muscle fatigue and dual-tasking had only minor effects on dynamic postural control of both young adults and seniors. Future studies should investigate why the fatigue-induced changes in quiet standing postural control do not seem to transfer to dynamic balance tasks. PMID:26834626

    To examine the potential risk factors for work-related fatigue (WRF) among workers in modern industries, the authors analyzed the records of need-for-recovery questionnaires and health checkup results for 1545 employees. Compared with regular daytime workers, and after adjusting for confounders, the workers adapting to day-and-night rotating shift work (RSW) had a 4.0-fold (95% confidence interval [CI] = 2.7-5.9) increased risk for WRF, higher than the 2.2-fold risk (95% CI = 1.5-3.3) for persistent shift workers. Based on highest education level, the male employees with university degrees had the highest adjusted odds ratio (a-OR) 2.8 (95% CI = 1.0-7.8) for complaining of WRF versus compulsory education group. For female workers, currently married/cohabiting status was inversely associated with WRF (a-OR = 0.5; 95% CI = 0.2-0.9), and child-rearing responsibility moderately increased WRF risk (a-OR = 1.9; 95% CI = 1.0-3.7). Day-and-night RSW and the adaptation, educational levels of males, and domestic factors for females contributed to WRF among semiconductor manufacturing employees. © 2013 APJPH.

    Purpose: Fatigue is an underevaluated cancer-related and treatment-related symptom. We analyzed fatigue in head and neck cancer patients undergoing radiotherapy (RT). Methods and Materials: A total of 117 patients were enrolled (mean age, 58 years). Radiation therapy (median dose, 66 Gy) was given with either exclusive or postoperative intent in 52 and 65 patients, respectively. Chemotherapy (CT) was added before and/or during RT in 61 patients. The patients completed a 20-item questionnaire (Multidimensional Fatigue Inventory [MFI-20]) before, during (weekly), and after RT. The impact of patient-, tumor-, and treatment-related factors on fatigue was evaluated with unifactorial and multifactorial tests. Results: Fatigue level increased during RT reaching a maximum at Week 6 and then slowly decreased. In multivariate stepwise regression analysis age (inversely related, p < 0.05), psychologic disorders (p < 0.005), and previous head-and-neck surgery (inversely related, p < 0.005) were correlated with higher pre-RT fatigue level. Pre-RT fatigue score (p < 0.0001), induction and/or concomitant CT (p = 0.035), need of cortisone during RT (p = 0.005), and thyroid disorders (p = 0.032) were correlated with higher during-RT fatigue level. Pre-RT fatigue score (p < 0.0001), induction and/or concomitant CT (p < 0.001), and need of cortisone during RT (p < 0.005) were correlated with higher post-RT fatigue level. No impact of gender, performance status, comorbidities other than psychologic and thyroid, tumor stage/site, RT intent, dose, volume, duration, or toxicity was observed. Conclusion: Fatigue affects all patients undergoing RT for head-and-neck cancer, reaches maximum score at the 6th week of RT, and slowly decreases thereafter. Age, thyroid dysfunction, psychologic disorders, pre-RT fatigue score, CT, and cortisone use are correlated with RT-related fatigue levels

    Since nutrition can influence the process of carcinogenesis, this study's objectives are to review the relationship between nutrition and cancer from the point of view of the role of micronutrients in the treatment of cancer patients, and to get to know the deficit relationship and the excess of micronutrients, with the etiology and cancer treatment. At the same time the patient's weight loss relates, among other things, to the type of cancerous tumor, its location, stage thereof, reason for which it may be associated with the deficiency of macro and micronutrients as from psychogenic, anorectics and mal-absorption effects or with mechanical effects as obstruction, among other toxic effects that are common in the treatment of cancer. Hence, the importance that the nutrition expert must have in making an adequate overall nutritional evaluation that allows the nutritional diagnosis, in studying the dietary patterns, to determine the toxic effects of the antineoplastic treatment in order to handle the treatment's timing excellence, symptoms and signs, and thus act effectively optiimizing the patient's life quality, and therewith his/her survival. There are controversies as to which specific dietary factors are related to cancer etiology and the results of studies on metabolic factors, and therefore, the relationship Cancer-Nutrition is quiet complex.

  11. Urological cancer related to familial syndromes

    Full Text Available ABSTRACT Cancer related to hereditary syndromes corresponds to approximately 5-10% of all tumors. Among those from the genitourinary system, many tumors had been identified to be related to genetic syndromes in the last years with the advent of new molecular genetic tests. New entities were described or better characterized, especially in kidney cancer such as hereditary leiomyomatosis renal cell carcinoma (HLRCC, succinate dehydrogenase kidney cancer (SDH-RCC, and more recently BAP1 germline mutation related RCC. Among tumors from the bladder or renal pelvis, some studies had reinforced the role of germline mutations in mismatch repair (MMR genes, especially in young patients. In prostate adenocarcinoma, besides mutations in BRCA1 and BRCA2 genes that are known to increase the incidence of high-risk cancer in young patients, new studies have shown mutation in other gene such as HOXB13 and also polymorphisms in MYC, MSMB, KLK2 and KLK3 that can be related to hereditary prostate cancer. Finally, tumors from testis that showed an increased in 8 - 10-fold in siblings and 4 - 6-fold in sons of germ cell tumors (TGCT patients, have been related to alteration in X chromosome. Also genome wide association studies GWAS pointed new genes that can also be related to increase of this susceptibility.

    Cancer-related cognitive impairment (CRCI) is a common, fatigue-related symptom that disrupts cancer survivors' quality of life. Few interventions for CRCI exist. As part of a randomized pilot study targeting cancer-related fatigue, the effects of mindfulness-based stress reduction (MBSR) on survivors' cognitive outcomes were investigated. Breast and colorectal cancer survivors (n = 71) with moderate-to-severe fatigue were randomized to MBSR (n = 35) or a fatigue education and support (ES; n = 36) condition. The Attentional Function Index (AFI) and the Stroop test were used to assess survivors' cognitive function at baseline (T1), after the 8-week intervention period (T2), and 6 months later (T3) using intent-to-treat analysis. Mediation analyses were performed to explore mechanisms of intervention effects on cognitive functioning. MBSR participants reported significantly greater improvement on the AFI total score compared to ES participants at T2 (d = 0.83, p = 0.001) and T3 (d = 0.55, p = 0.021). MBSR also significantly outperformed ES on most AFI subscales, although both groups improved over time. MBSR produced greater Stroop accuracy rates relative to ES at T2 (r = 0.340, p = 0.005) and T3 (r = 0.280, p = 0.030), with improved accuracy over time only for the MBSR group. There were no significant differences in Stroop reaction time between groups. Improvements in mindfulness mediated the effect of group (e.g., MBSR vs. ES) on AFI total score at T2 and T3. Additional randomized trials with more comprehensive cognitive measures are warranted to definitively assess the efficacy of MBSR for CRCI. This pilot study has important implications for all cancer survivors as it is the first published trial to show that MBSR offers robust and durable improvements in CRCI.

    2014-09-01

    Full Text Available Fatigue is a common symptom of numerous acute and chronic diseases, including myalgic encephalomyelitis/chronic fatigue syndrome, multiple sclerosis, heart failure, cancer, and many others. In these multi-system diseases the physiological determinants of enhanced fatigue encompass a combination of metabolic, neurological, and myofibrillar adaptations. Previous research studies have focused on adaptations specific to skeletal muscle and their role in fatigue. However, most have neglected the contribution of physical inactivity in assessing disease syndromes, which, through deconditioning, likely contributes to symptomatic fatigue. In this commentary, we briefly review disease-related muscle phenotypes in the context of whether they relate to the primary disease or whether they develop secondary to reduced physical activity. Knowledge of the etiology of the skeletal muscle adaptations in these conditions and their contribution to fatigue symptoms is important for understanding the utility of exercise rehabilitation as an intervention to alleviate the physiological precipitants of fatigue.

    Web and mobile technologies appear to hold promise for delivering evidence-informed and evidence-based intervention to cancer survivors and others living with trauma and other psychological concerns. Health-space.net was developed as a comprehensive online social networking and coping skills training program for cancer survivors living with distress. The purpose of this study was to evaluate the effects of a 12-week social networking intervention on distress, depression, anxiety, vigor, and fatigue in cancer survivors reporting high levels of cancer-related distress. We recruited 347 participants from a local cancer registry and internet, and all were randomized to either a 12-week waiting list control group or to immediate access to the intervention. Intervention participants received secure access to the study website, which provided extensive social networking capabilities and coping skills training exercises facilitated by a professional facilitator. Across time, the prevalence of clinically significant depression symptoms declined from 67 to 34 % in both conditions. The health-space.net intervention had greater declines in fatigue than the waitlist control group, but the intervention did not improve outcomes for depression, trauma-related anxiety symptoms, or overall mood disturbance. For those with more severe levels of anxiety at baseline, greater engagement with the intervention was associated with higher levels of symptom reduction over time. The intervention resulted in small but significant effects on fatigue but not other primary or secondary outcomes. Results suggest that this social networking intervention may be most effective for those who have distress that is not associated with high levels of anxiety symptoms or very poor overall psychological functioning. The trial was registered with the ClinicalTrials.gov database ( ClinicalTrials.gov #NCT01976949).

    After being diagnosed with lung cancer, patients often experience sleep disturbance, anxiety, depression, and fatigue. These symptoms may occur because of changes in neurotransmitter secretion caused by tumors. This study investigated the correlation of cortisol and melatonin rhythms with sleep quality, anxiety, depression, and fatigue levels in patients with newly diagnosed lung cancer. We conducted a case-control study and recruited 40 patients with newly diagnosed lung cancer and 40 healthy adults. The patient group had a lower salivary melatonin level and flatter slope (p cortisol level and steeper slope (p cortisol slope (p = 0.005) and fatigue score (p = 0.032) predicted the sleep quality score (p = 0.011). Overall, the patients with newly diagnosed lung cancer had poorer sleep quality, higher depression levels, lower salivary melatonin levels, higher cortisol levels, and flatter melatonin and cortisol slopes than did the controls. The fatigue level and cortisol slope significantly predicted sleep quality. Therefore, the assessment of cortisol and melatonin rhythms and levels could provide crucial information that may be beneficial for managing symptoms in patients with newly diagnosed lung cancer.

    To determine whether non-physical activity mind and body practices reduce the severity of fatigue in patients with cancer or hematopoietic stem cell transplant (HSCT) recipients compared to control interventions. We included randomized trials which compared non-physical activity mind and body practices compared with control interventions for the management of fatigue in cancer and HSCT patients. Among 55 trials (4975 patients), interventions were acupuncture or acupressure (n=12), mindfulness (n=11), relaxation techniques (n=10), massage (n=6), energy therapy (n=5), energizing yogic breathing (n=3) and others (n=8). When combined, all interventions significantly reduced fatigue severity compared to all controls (standardized mean difference -0.51, 95% confidence interval -0.73 to -0.29). More specifically, mindfulness and relaxation significantly reduced fatigue severity. Mindfulness and relaxation were effective at reducing fatigue severity in patients with cancer and HSCT recipients. Future studies should evaluate how to translate these findings into clinical practice across different patient groups. Copyright © 2017 Elsevier B.V. All rights reserved.

    To evaluate tolerability and compliance to a walking exercise program and its effect on fatigue during and after radical external beam radiation therapy (EBRT) for prostate cancer. A total of 50 subjects with prostate cancer undergoing EBRT over 6 to 8 weeks were prospectively accrued to an exercise intervention group, matched for age and clinical characteristics to 30 subjects in a historical control group who underwent EBRT with no specific exercise intervention. Starting 1 week before EBRT, exercise participants performed moderate-intensity walking targeting 60% to 70% age-predicted maximum heart rate, at least 20 min/d, 3 d/wk over 12 weeks. The Brief Fatigue Inventory was administered at baseline, mid-EBRT (week 3-4), end-EBRT (week 6-8), and 6 months post-EBRT. Of 50, 42 (84%) of exercise participants completed the walking program. There were no cardiovascular complications, musculoskeletal injuries, or other adverse events. A total of 89% subjects reported "Good-Excellent" satisfaction during and up to 6 months post-EBRT. Fatigue in control subjects escalated from baseline to end-EBRT, remaining high at 6 months post-EBRT (P[r] = 0.03). In contrast, mean total fatigue scores in exercise subjects were stable from baseline up to 6 months post-EBRT (P = 0.52). Trends for higher fatigue interference with quality of life were observed in the control group as compared with the exercise group. Moderate-intensity walking exercise during radical EBRT is safe and feasible. The high convenience and satisfaction ratings, in conjunction with the observed fatigue trends, indicate that this activity has the potential to attenuate fatigue and improve quality of life for patients with localized prostate cancer undergoing curative therapy.

    The rolling-contact fatigue spin rig was used to test groups of SAE 52100 9.16-inch-diameter balls lubricated with a mineral oil at 600,000-, 675,000-, and 750,000-psi maximum Hertz stress. Cylinders of AISI M-1 vacuum and commercial melts and MV-1 (AISI M-50) were used as race specimens. Stress-life exponents produced agree closely with values accepted in industry. The type of failure obtained in the spin rig was similar to the subsurface fatigue spells found in bearings.

    Marfan syndrome (MFS) is a severe autosomal dominant connective tissue disorder that might influence peoples work ability. This cross sectional study aims to investigate work participation in adults with verified MFS diagnosis and to explore how the health related consequences of MFS and other factors might influence work participation. The prevalence of health problems in young adults compared to older adults with MFS was examined in association to work participation. A postal questionnaire including questions about work participation, demographic characteristics, MFS related health problems, chronic pain, and fatigue was sent to 117 adults with verified MFS (Ghent 1), and 62% answered. Fifty-nine percent were employed or students, significantly lower work participation than the General Norwegian Population (GNP), but higher than the Norwegian population of people with disability. Most young adults worked full-time despite extensive health problems, but the average age for leaving work was low. Few had received any work adaptations prior to retiring from work. In multiple logistic regression analysis, only age, lower educational level and severe fatigue were significantly associated with low work participation; not MFS related health problems or chronic pain. Fatigue appears to be the most challenging health problem to deal with in work, but the covariance is complex. Focus on vocational guidance early in life, more appropriate work adaptations, and psychosocial support might improve the possibility for sustaining in work for adults with MFS. More research about work challenges in adults with MFS is needed. © 2015 Wiley Periodicals, Inc.

     AbstractBackground: Fatigue could impair cognitive function in pilots which may lead to accidents in short-haul flight. Theaim of this study was to identify the risk factors related to fatigue among short-haul commercial pilots in Indonesia.Methods: A cross-sectional study with purposive sampling was conducted among Boeing 737 seriestyped-rating pilots taking medical examination at the Civil Aviation Medical Center, Jakarta from May5-26, 2014. Fatigue was measured with Self-Reporting Questionnaire, Fatigue Severity Scale (FSS. Datawere collected using anonymous self-reporting questionnaire on demographics, workload, sleep restriction(Epworth Sleepiness Scale-ESS, personal factors, and managerial support. Linear regression was used toidentify dominant risk factors related to fatigue.Results: During data collection, 785 pilots were taking medical examination, 382 pilots were willing toparticipate, and 239 pilots met the criteria. The FSS mean was 4.66 ± 1.202. The number of sectors in 24hours, flight times of unplanned flights in 30 days, and sleep restriction were dominant factors of fatigue.Each additional sector increased FSS by 0.371 points [regression coefficient (β = 0.371; P = 0.000].Furthermore, each additional ESS, increased FSS by 0.043 points (β = 0.043; P = 0.008, while eachadditional unplanned flights increased FSS by 0.033 points (β = 0.033; P = 0.000.Conclusions: Additional number of sectors in 24 hours, additional unplanned flight times within 30 days,and sleep restriction increased the risk of fatigue among short-haul commercial pilots in Indonesia.

    This study aims to establish the prevalence of high work-related fatigue (need for recovery, NFR) among employees and to explain group differences categorized by gender, age, and education. The study particularly aims to clarify prevalence and explanatory factors in highly educated women. In 2005 and 2006, large representative samples of 80,000 Dutch employees (net response rate 33.0%; N = 47,263) received the Netherlands working conditions survey questionnaire. First, we calculated the prevalence of high NFR for men and women with different age and education levels. The average prevalence of high NFR was 28.8% and was highest among highly educated women (35.2%) in particular those aged 50-64 years (40.3%). Second, logistic regression analyses were used to compare subgroups' NFR in relation to situational factors, working conditions, and health. Three comparisons were made: (1) highly educated women versus men; (2) highly educated versus lower educated women and; (3) older highly educated versus younger highly educated women. The situational, working conditions and health factors in our model did not explain the gender differences among highly educated employees (OR = 1.37; CI = 1.3-1.5, adjusted for all factors OR = 1.32; CI = 1.2-1.5). Despite that lower autonomy and workplace violence explained highly educated women's NFR, working fewer hours counterbalanced this. Time pressure in work largely explained the differences in NFR among women at different education levels (crude OR 1.44; CI = 1.4-1.5, adjusted OR 1.14; CI = 1.0-1.3). In the age comparison, lower health ratings, more adverse working conditions, and working as a teacher explained older highly educated women's high prevalence of high NFR (crude OR 1.32; CI = 1.2-1.5, adjusted OR 0.94; CI = 0.8-1.2). NFR has high prevalence in highly educated women (35.2%) in particular those aged 50-64 years (40.3%). Our model did not explain gender differences in NFR, because working fewer hours counterbalanced the

    Fatigue is a multidimensional concept covering both physiological and psychological aspects. Chronic fatigue is a typical symptom of diseases such as cancer, multiple sclerosis (MS), Parkinson's disease (PD) and cerebrovascular disorders but is also presented by people in whom no defined somatic disease has been established. If certain criteria are met, chronic fatigue syndrome can be diagnosed. The 4-item Abbreviated Fatigue Questionnaire allows the extent of the experienced fatigue to be assessed with a high degree of reliability and validity. Physiological fatigue has been well defined and originates in both the peripheral and central nervous system. The condition can be assessed by combining force and surface-EMG measurements (including frequency analyses and muscle-fibre conduction estimations), twitch interpolation, magnetic stimulation of the motor cortex and analysis of changes in the readiness potential. Fatigue is a well-known phenomenon in both central and peripheral neurological disorders. Examples of the former conditions are multiple sclerosis, Parkinson's disease and stroke. Although it seems to be a universal symptom of many brain disorders, the unique characteristics of the concomitant fatigue also point to a specific relationship with several of these syndromes. As regards neuromuscular disorders, fatigue has been reported in patients with post-polio syndrome, myasthenia gravis, Guillain-Barré syndrome, facioscapulohumeral dystrophy, myotonic dystrophy and hereditary motor and sensory neuropathy type-I. More than 60% of all neuromuscular patients suffer from severe fatigue, a prevalence resembling that of patients with MS. Except for several rare myopathies with specific metabolic derangements leading to exercise-induced muscle fatigue, most studies have not identified a prominent peripheral cause for the fatigue in this population. In contrast, the central activation of the diseased neuromuscular system is generally found to be suboptimal. The

    Advice to rest and take things easy if patients become fatigued during radiotherapy may be detrimental. Aerobic walking improves physical functioning and has been an intervention for chemotherapy-related fatigue. A prospective, randomized, controlled trial was performed to determine whether aerobic exercise would reduce the incidence of fatigue and prevent deterioration in physical functioning during radiotherapy for localized prostate carcinoma. Sixty-six men were randomized before they received radical radiotherapy for localized prostate carcinoma, with 33 men randomized to an exercise group and 33 men randomized to a control group. Outcome measures were fatigue and distance walked in a modified shuttle test before and after radiotherapy. There were no significant between group differences noted with regard to fatigue scores at baseline (P = 0.55) or after 4 weeks of radiotherapy (P = 0.18). Men in the control group had significant increases in fatigue scores from baseline to the end of radiotherapy (P = 0.013), with no significant increases observed in the exercise group (P = 0.203). A nonsignificant reduction (2.4%) in shuttle test distance at the end of radiotherapy was observed in the control group; however, in the exercise group, there was a significant increase (13.2%) in distance walked (P = 0.0003). Men who followed advice to rest and take things easy if they became fatigued demonstrated a slight deterioration in physical functioning and a significant increase in fatigue at the end of radiotherapy. Home-based, moderate-intensity walking produced a significant improvement in physical functioning with no significant increase in fatigue. Improved physical functioning may be necessary to combat radiation fatigue.

  13. Evidence-based efficacy of adaptogens in fatigue, and molecular mechanisms related to their stress-protective activity.

    2009-09-01

    The aim of this review article is to assess the level of scientific evidence presented by clinical trials of adaptogens in fatigue, and to provide a rationale at the molecular level for verified effects. Strong scientific evidence is available for Rhodiola rosea SHR-5 extract, which improved attention, cognitive function and mental performance in fatigue and in chronic fatigue syndrome. Good scientific evidence has been documented in trails in which Schisandra chinensis and Eleutherococcus senticosus increased endurance and mental performance in patients with mild fatigue and weakness. Based on their efficacy in clinical studies, adaptogens can be defined as a pharmacological group of herbal preparations that increase tolerance to mental exhaustion and enhance attention and mental endurance in situations of decreased performance. The beneficial stress-protective effect of adaptogens is related to regulation of homeostasis via several mechanisms of action associated with the hypothalamic-pituitary-adrenal axis and the control of key mediators of stress response such as molecular chaperons (e.g. Hsp70), stress-activated c-Jun N-terminal protein kinase (JNK1), Forkhead Box O transcription factor DAF-16, cortisol and nitric oxide (NO). The key point of action of phytoadaptogens appears to be their up-regulating and stress-mimetic effects on the "stress-sensor" protein Hsp70, which plays an important role in cell survival and apoptosis. Hsp70 inhibits the expression of NO synthase II gene and interacts with glucocorticoid receptors directly and via the JNK pathway, thus affecting the levels of circulating cortisol and NO. Prevention of stress-induced increase in NO, and the associated decrease in ATP production, results in increased performance and endurance. Adaptogen-induced up-regulation of Hsp70 triggers stress-induced JNK-1 and DAF-16-mediated pathways regulating the resistance to stress and resulting in enhanced mental and physical performance and, possibly

    To evaluate the association between fatigue and anti-epidermal growth factor receptor monoclonal antibodies (anti-EGFR MAbs), we conducted the first meta-analysis to access the incidence and risk of fatigue associated with anti-EGFR MAbs. Electronic databases were searched for randomized controlled trials (RCTs) published up to February 2017. Eligible studies were selected according to PRISMA statement. Incidence rates, risk ratio (RRs), and 95% confidence intervals (CIs) were calculated using fixed-effects or random-effects models. Outcomes of quality were summarized in accordance with the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology. Thirty-five RCTs (including 15,622 patients) were included; median follow-up ranged from 8.1 to 71.4 months, and the fatigue events were recorded and graded according to the Common Toxicity Criteria for Adverse Events version 2.0 or 3.0 in most of the included trials. For patients receiving anti-EGFR MAbs, the overall incidence of all-grade and high-grade fatigue was 54.1% and 10.5%, respectively. Compared with control, anti-EGFR MAbs significantly increased the risk of all-grade fatigue (RR 1.10, 95% CI, 1.05-1.14, moderate-quality evidence) and high-grade fatigue (RR 1.31, 95% CI, 1.19-1.45, moderate-quality evidence). No significant differences among subgroup analyses (anti-EGFR MAbs, tumor type, and median follow-up) on high-grade fatigue were observed. No evidence of publication bias was observed. The present study suggested that anti-EGFR MAbs may increase the risk of fatigue in cancer patients.

  15. Symptom clusters in cancer patients and their relation to EGFR ligand modulation of the circadian axis.

    Recent studies in chronobiology and the neurosciences have led to rapid growth in our understanding of the molecular biology of the human timekeeping apparatus and the neuroanatomic sites involved in signaling between the "master clock" in the hypothalamus and other parts of the brain. The circadian axis comprises a central clock mechanism and a downstream network of hypothalamic relay stations that modulate arousal, feeding, and sleeping behavior. Communication between the clock and these hypothalamic signaling centers is mediated, in part, by diffusible substances that include ligands of the epidermal growth factor receptor (EGFR). Preclinical studies reveal that EGFR ligands such as transforming growth factor-alpha (TGF-alpha) inhibit hypothalamic signaling of rhythmic behavior; clinical observations show that elevated levels of TGF-alpha are associated with fatigue, flattened circadian rhythms, and loss of appetite in patients with metastatic colorectal cancer. These data support the hypothesis that a symptom cluster of fatigue, appetite loss, and sleep disruption commonly seen in cancer patients may be related to EGFR ligands, released either by the cancer itself or by the host in response to the stress of cancer, and suggest that further examination of their role in the production of symptom clustering is warranted.

    Full Text Available Cancer stem cells (CSCs, with their self-renewal ability and multilineage differentiation potential, are a critical subpopulation of tumor cells that can drive tumor initiation, growth, and resistance to therapy. Like embryonic and adult stem cells, CSCs express markers that are not expressed in normal somatic cells and are thus thought to contribute toward a “stemness” phenotype. This review summarizes the current knowledge of stemness-related markers in human cancers, with a particular focus on important transcription factors, protein surface markers, and signaling pathways.

  19. ASME Section XI philosophy related to operating nuclear plant fatigue damage protection

    International Nuclear Information System (INIS)

    Gosselin, S.R.

    1995-01-01

    When faced with operating fatigue concerns, nuclear plants traditionally look to the requirements contained in the original construction design code, ASME Section 3, as a basis for component operability. These rules constitute the requirements for nuclear power plant vessel and component construction and, when combined with the Owner's Design Specification, provide reasonable assurance of reliable operation. However, once construction is complete and operation begins, the purpose of any subsequent evaluations shifts from component ''design qualification'' to component ''fitness for service.'' This is a role that has been assumed for ASME Section 11. This paper presents a philosophy, recently endorsed by the ASME Section 11 Executive Committee, intended to guide future Code activities regarding fatigue and its impact on component serviceability

    Fatigue-related crashes have long been the topic of discussion and study worldwide. The relationship between fatigue-related crashes and time of day is well documented. In Malaysia, the possibility of banning express buses from operating during the early-hours of the morning has emerged as an important consideration for passenger safety. This paper highlights the findings of an impact assessment study. The study was conducted to determine all possible impacts prior to the government making any decision on the proposed banning. This study is an example of a simple and inexpensive approach that may influence future policy-making process. The impact assessment comprised two major steps. The first step involved profiling existing operation scenarios, gathering information on crashes involving public express buses and stakeholders' views. The second step involved a qualitative impact assessment analysis using all information gathered during the profiling stage to describe the possible impacts. Based on the assessment, the move to ban early-hour operations could possibly result in further negative impacts on the overall road safety agenda. These negative impacts may occur if the fundamental issues, such as driving and working hours, and the need for rest and sleep facilities for drivers, are not addressed. In addition, a safer and more accessible public transportation system as an alternative for those who choose to travel at night would be required. The proposed banning of early-hour operations is also not a feasible solution for sustainability of express bus operations in Malaysia, especially for those operating long journeys. The paper concludes by highlighting the need to design a more holistic approach for preventing fatigue-related crashes involving express buses in Malaysia. Copyright © 2011 Elsevier Ltd.

    To describe fatigue and its relationship to cognition, psychosocial adjustment, quality of life (QoL), work status and relative's experiences 12 months after suspected traumatic axonal injury (TAI). Eighteen patients were assessed with the Daily Fatigue Impact Scale (D-FIS), the Barrow Neurological Institute Screen for Higher Cerebral Functions (BNIS), the European Questionnaire 5 Dimensions health-related quality of life, the Glasgow Coma Outcome Scale Extended, and the European Brain Injury Questionnaire (EBIQ) (patient and relative). Return to work was registered. At 1 year, fatigue still caused great problems in daily life. Although fatigue and cognition (BNIS) did not correlate, the more fatigued patients subjectively experienced significantly more cognitive dysfunction. Although D-FIS and QoL did not correlate, most patients reported that feelings of tiredness and dullness related to having lower QoL. However, lower QoL was associated with cognitive and attention disability (BNIS), subjective perception of executive dysfunction, lack of motivation, and mood disturbances (EBIQ). Neither fatigue nor cognition associated with return to work. The general consequences of TAI showed good agreement between patients' and relatives' experiences. The patient's subjective experience of the impact of TAI seems to be most essential, as it is the objective reality that the patient responds to, and this should therefore be assessed and treated.

    Gage-Bouchard, Elizabeth A; LaValley, Susan; Mollica, Michelle; Beaupin, Lynda Kwon

    Americans are increasingly using social media (such as Facebook, YouTube, and Twitter) for health-related communication. Much of the previous research on social media and health communication has focused on Facebook groups related to a specific disease or Facebook pages related to an advocacy organization. Less is known about how people communicate about cancer on personal Facebook pages. In this study, we expand upon previous research by examining how cancer caregivers use personal Facebook pages for cancer-related communication. We examined themes in cancer-related exchanges through a content analysis of 12 months of data from 18 publically available Facebook pages hosted by parents of children with acute lymphoblastic leukemia (15 852 total posts). Six themes emerged: (1) documenting the cancer journey, (2) sharing emotional strain associated with caregiving, (3) promoting awareness and advocacy about pediatric cancer, (4) fundraising, (5) mobilizing support, and (6) expressing gratitude for support. Building upon previous research documenting the increasing use of social media for health-related communication and support, our findings show that personal Facebook pages offer a platform for cancer caregivers to share their cancer-related experiences, promote advocacy and awareness, and mobilize social support. Providers must recognize the importance of social media as a vehicle for support and communication for families of children with cancer. Nurses should educate parents on how to appraise information obtained through Facebook using evidence-based guidelines. Providers can encourage caregivers to use Facebook as a tool for communication, information, and support.

    2017-05-01

    Full Text Available Introduction: Taste change due to cancer is a notorious side effect, adversely affecting appetite and weight. Even though taste change or dysgeusia is one of the major causes of poor nutritional status in cancer survivors, it is not addressed as a significant problem and is often left untreated. The main purpose of this review is to explore current knowledge of pharmacological and behavioral interventions for the treatment of cancer related taste change. Methods: This systematic review was conducted in accordance with PRISMA guidelines to identify original articles on taste change. Multiple databases including; Scopus, Medline, EMBASE, CINAHL, and all databases via Pro quest were searched for original articles or studies related to taste change caused by cancer or its treatment. Relevant articles were subjected to a full text evaluation and assessed by Critical appraisal skills program (CASP guidelines and the Effective public health practice project (EPHPP instrument. Results: The search revealed 12 eligible studies, six of which were randomized controlled trials. Most of the studies used a standardized validated tool to measure taste change. Dysgeusia is common in cancer, 14 to 100% cancer patient report it. Pharmacological management with zinc remains inconclusive as one study reports it as beneficial and two other studies reported null effect. Few studies suggested dietary modifications such as use of sugary, salty foods that are helpful to reduce the effect of dysgeusia. Conclusion: Dietary counseling and informing the patient well about self-care strategies before treatment has consistently shown positive results on taste change, with strong statistical power. Other potential treatments for dysgeusia such as zinc, amifostine, and megestrol acetate gave inconsistent results.

  5. Relations Between Self-Reported Daily-Life Fatigue, Hearing Status, and Pupil Dilation During a Speech Perception in Noise Task.

    People with hearing impairment are likely to experience higher levels of fatigue because of effortful listening in daily communication. This hearing-related fatigue might not only constrain their work performance but also result in withdrawal from major social roles. Therefore, it is important to understand the relationships between fatigue, listening effort, and hearing impairment by examining the evidence from both subjective and objective measurements. The aim of the present study was to investigate these relationships by assessing subjectively measured daily-life fatigue (self-report questionnaires) and objectively measured listening effort (pupillometry) in both normally hearing and hearing-impaired participants. Twenty-seven normally hearing and 19 age-matched participants with hearing impairment were included in this study. Two self-report fatigue questionnaires Need For Recovery and Checklist Individual Strength were given to the participants before the test session to evaluate the subjectively measured daily fatigue. Participants were asked to perform a speech reception threshold test with single-talker masker targeting a 50% correct response criterion. The pupil diameter was recorded during the speech processing, and we used peak pupil dilation (PPD) as the main outcome measure of the pupillometry. No correlation was found between subjectively measured fatigue and hearing acuity, nor was a group difference found between the normally hearing and the hearing-impaired participants on the fatigue scores. A significant negative correlation was found between self-reported fatigue and PPD. A similar correlation was also found between Speech Intelligibility Index required for 50% correct and PPD. Multiple regression analysis showed that factors representing "hearing acuity" and "self-reported fatigue" had equal and independent associations with the PPD during the speech in noise test. Less fatigue and better hearing acuity were associated with a larger pupil

    In addition to the underlying health problems and disability associated with multiple sclerosis (MS) and cardiovascular disease (CVD), adults with each of these chronic illnesses are independently known to experience fatigue. While fatigue's influence on physical activity and health related quality of life (HRQOL) with each of these illnesses has been discussed, what is lacking is information on how fatigue impacts physical activity and health related quality of life, and ultimately self-management for adults with these conditions. Additionally, individuals may be unaware of the significance of maintaining optimal physical activity in order to maintain everyday function and self-management. Thus, the purpose of this article is to discuss the complex effect of fatigue on physical activity and HRQOL among adults with MS and CVD, and to present potential self-management strategies.

    We report a case of rhabdomyolysis related to S-1 plus oxaliplatin(SOX)therapy for liver metastasis of gastric cancer. A 76- year-old man who had received SOX therapy for metastatic gastric cancer was admitted to our hospital for a chief complaint of fatigue and weakness. He diagnosed with rhabdomyolysis related to SOX therapy because of his symptoms and because his laboratory studies showed significant elevation of his serum creatine kinase(CK)level. The symptoms disappeared and the CK level normalized following large-volume transfusions. Rhabdomyolysis following SOX therapy is a very rare, but severe adverse event. This is the first detailed case report of rhabdomyolysis related to SOX therapy.

    The process of friction has been treated within the framework of an ergodynamic concept of deformable bodies. Equations of the friction energy balance are derived and a structure-energy interpretation of the friction process proposed. The friction parameter ranges within the domain of compatibility have been computed for tribosystems. The friction coefficient is shown to be a characteristic of the fatigue, wear resistance, and order (disorder) parameter of a tribosystem. Equations of state of a tribosystem and universal friction constants have been proposed. 31 refs.; 2 figs.; 3 tabs

    This pilot exploratory study aimed to compare the health-related quality of life (HRQOL) among patients diagnosed with different types of cancer receiving peripherally inserted central catheters (PICCs). A multicenter cross-section study of cancer patients with PICCs was performed from February 1, 2013 to April 24, 2014. The primary objective of this study was to compare HRQOL in different cancer type patients with PICC. HRQOL was examined based on European Organisation for Research and Treatment of Cancer Quality-of-Life Questionnaire-Core 30 (EORTC QLQ-C30). Multiple linear regression models were conducted for coping with potential confounding variables. We also examined PICC-related quality of daily life with a self-made questionnaire. Three hundred and fifty-seven cancer patients with PICC completed the survey in nine teaching hospitals. Lung cancer patients with PICC reported the worst dyspnea. Digestive tract cancer patients reported the worst appetite loss. Patients with hematologic malignancy reported the worst emotional, social function, fatigue and financial impact. Breast cancer patients reported better HRQOL. Baseline variables were proven not significant predictors of EORTC QLQ-C30 global health status. In self-made survey, pain after PICC insertion was null or a little in 98.6% of cancer patients. Limitation of upper extremity activity was null or a little in 94.1% of patients. HRQOL varies in different types of cancer patients with PICC. PICC may have a low impact on cancer patients' HRQOL. Further large sample studies are needed.

    Directory of Open Access Journals (Sweden)

    Juriena D de Vries

    Full Text Available Many university students experience high levels of study-related fatigue. This high prevalence, and the negative impact of fatigue on health and academic performance, call for prevention and reduction of these symptoms. The primary aim of the current study was to investigate to what extent an exercise intervention is effective in reducing three indicators of study-related fatigue (emotional exhaustion, overall fatigue, and need for recovery. Effects of exercise on secondary outcomes (sleep quality, self-efficacy, physical fitness, and cognitive functioning were also investigated.Participants were students with high levels of study-related fatigue, currently not exercising or receiving other psychological or pharmacological treatments, and with no medical cause of fatigue. They were randomly assigned to either a six-week exercise intervention (low-intensity running three times a week, n = 49 or wait list (no intervention, n = 48. All participants were measured before the intervention (T0, and immediately after the intervention (T1. Exercisers were also investigated 4 weeks (T2 and 12 weeks (T3 after the intervention.Participants in the exercise condition showed a larger decrease in two of the three indicators of study-related fatigue (i.e., overall fatigue and need for recovery as compared to controls. Additionally, sleep quality and some indicators of cognitive functioning improved more among exercisers than among controls. No effects were found for self-efficacy, and physical fitness. The initial effects of the exercise intervention lasted at follow-up (T2 and T3. At 12-week follow up (T3, 80% of participants in the exercise condition still engaged in regular exercise, and further enhancements were seen for emotional exhaustion, overall fatigue, and sleep quality.These results underline the value of low-intensity exercise for university students with high levels of study-related fatigue.

    Cornelia Nitipir

    2018-04-01

    Full Text Available The incidence of thyroid cancer is significantly different between male and female patients. Thyroid cancer is also the only form of cancer where age can be considered a staging variable. Identifying biological prognostic factors such as age or sex is important as it helps select an optimal personalized therapy. The present analysis is an observational, prospective study that enrolled all patients with thyroid disease who were operated upon at a single center. The study aimed to determine the most frequent age at presentation, the predominance of one sex over the other, the incidence of malignant thyroid disease, and the relative risk for each sex to develop thyroid carcinoma. The incidence of thyroid carcinoma was higher for women than for men, with a higher relative risk in the female subgroup. Incidence was also highest in the 50-60-year-old group. Given that studies show better survival for women and for younger patients, even when presenting with advanced disease, compared with older, male patients, such prognostic indicators should be a factor in the treatment decision.

    Indian underground mining (UGM) transport system largely deals with different fore and back bearing work processes associated with different occupational disorders and fatigue related work stress disorders (FRWSDs). Therefore, this research study is specifically aimed to determine the fatigue related problems in general and determination of Recovery Heart Rate (Rec HR) pattern and exact cause of FRWSDs in particular. A group of twenty (N = 20) UGM operators are selected for the study. Heart rate profiles and work intensities of selected workforces have been recorded continuously during their regular mine operation and the same workforces are tested on a treadmill on surface with almost same work intensity (%Maximal Heart Rate) which was earlier observed in the mine. Recovery Heart Rate (Rec HR) in both the experiment zones is recorded. It is observed that with almost same work intensity, the recovery patterns of submaximal prolonged work in mine are different as compared to treadmill. This research study indicates that non-biomechanical muscle activity along with environmental stressors may have an influence on recovery pattern and FRWSDs.

    2009-03-01

    This paper investigates theoretically the influence of magnetization on fatigue life by using non-equilibrium statistical theory of fatigue fracture for metals. The fatigue microcrack growth rate is obtained from the dynamic equation of microcrack growth, where the influence of magnetization is described by an additional term in the potential energy of microcrack. The statistical value of fatigue life of metal under magnetic field is derived, which is expressed in terms of magnetic field and macrophysical as well as microphysical quantities. The fatigue life of AISI 4140 steel in static magnetic field from this theory is basically consistent with the experimental data.

    Full Text Available The impairing effects of mental fatigue on visual sustained attention were assessed by event-related potentials (ERPs. Subjects performed a dual visual task, which includes a continuous tracking task (primary task and a random signal detection task (secondary task, for 63 minutes nonstop in order to elicit ERPs. In this period, the data such as subjective levels of mental fatigue, behavioral performance measures, and electroencephalograms were recorded for each subject. Comparing data from the first interval (0-25 min to that of the second, the following phenomena were observed: the subjective fatigue ratings increased with time, which indicates that performing the tasks leads to increase in mental fatigue levels; reaction times prolonged and accuracy rates decreased in the second interval, which indicates that subjects' sustained attention decreased.; In the ERP data, the P3 amplitudes elicited by the random signals decreased, while the P3 latencies increased in the second interval. These results suggest that mental fatigue can modulate the higher-level cognitive processes, in terms of less attentional resources allocated to the random stimuli, which leads to decreased speed in information evaluating and decision making against the stimuli. These findings provide new insights into the question that how mental fatigue affects visual sustained attention and, therefore, can help to design countermeasures to prevent accidents caused by low visual sustained attention.

    Non-restorative sleep is a hallmark symptom of chronic fatigue syndrome/myalgic encephalomyelitis. However, little is known about self-reported sleep disturbances in these subjects. This study aimed to assess the self-reported sleep quality and its impact on quality of life in a Spanish community-based chronic fatigue syndrome/myalgic encephalomyelitis cohort. A prospective cross-sectional cohort study was conducted in 1,455 Spanish chronic fatigue syndrome/myalgic encephalomyelitis patients. Sleep quality, fatigue, pain, functional capacity impairment, psychopathological status, anxiety/depression and health-related quality of life were assessed using validated subjective measures. The frequencies of muscular, cognitive, neurological, autonomic and immunological symptom clusters were above 80%. High scores were recorded for pain, fatigue, psychopathological status, anxiety/depression, and low scores for functional capacity and quality of life, all of which correlated significantly (all p quality of sleep as measured by the Pittsburgh Sleep Quality Index.

    Fatigue life estimates obtained with the local strain approach (LSA) and with the conventional nominal stress approach (NSA) were compared with experimental results obtained on notched AlCuMg2 aircraft material specimens with flight simulation random tensile loading. The effect of change of the reference stress, of the loading program and of some changes in the loading frequency distribution, on the ratio Nsub(exp)/Nsub(pred) was investigated. A material strain-life curve, a cyclic stress-strain curve. The Neuber-Topper rule Ksub(sigma) x Ksub(epsilon) = K 2 = const. and a K value estimated with an exact two-parameter notch factor formula for the case R = 0, N = 10 7 were used for life predictions.

  2. Studies on the fatigue of branched connections related to the shakedown pressure

    Cook, T.R.

    1977-01-01

    The concept of shakedown is that regions which plastically deform during initial loading subsequently adopt an elastic mode of deformation. High strain fatigue, i.e. up to 10,000 cycles, will be eliminated. Two branches of different thickness were welded to a common cylindrical vessel and hydraulically tested, simultaneously. The test pressure was the shakedown limit for the stronger branch and about 1.5 x shakedown for the weaker branch. The thinner branch failed by penetration through the weld near the crotch corner at 3,543 cycles. The thicker branch was given 10,000 cycles when, since no cracks were apparent, a starter notch was made in the crotch corner. Leakage occurred after another 10,678 cycles. This crack was also influenced by weld defects. Using fracture mechanics and a reported relationship between crack rate and stress intensity factors, some predictions of endurance at design pressure are derived for these branches. These lives are compared with the British Standard 1515 formula for fatigue avoidance and with the curves given in Section III of the ASME Boiler and Pressure Vessel Code. The former is considered conservative, while the ASME Code curve requires an additional safety factor as suggested by Jettam; A multiplication factor of 2 on the nominal stress concentration factor for welds is then considered satisfactory. It is tentatively considered that such junctions manufactured to Class 1 standard are satisfactory for daily cycling for 30 years, but are marginal for twice daily cycling for that time. This conclusion is tentative, since it depends critically on the size of weld defects present

    This article gives an overview of the established radionuclide therapies for endocrine-related cancer that already have market authorization or are currently under evaluation in clinical trials. Radioiodine therapy is still the gold standard for differentiated iodine-avid thyroid cancer. In patients with bone and lung metastases (near) total remission is seen in approximately 50 % and the 15-year survival rate for these patients is approximately 90 %. In contrast to the USA, meta-iodobenzylguanidine (MIBG) therapy has market approval in Europe. According to the current literature, in the setting of advanced stage neuroblastoma and malignant pheochromocytoma or paraganglioma, radiological remission can be achieved in > 30 % and symptom control in almost 80 % of the treated patients. Somatostatin receptor targeted radionuclide therapies (e.g. with DOTATATE or DOTATOC) demonstrated promising results in phase 2 trials, reporting progression-free survival in the range of 24-36 months. A first phase 3 pivotal trial for intestinal carcinoids is currently recruiting and another trial for pancreatic neuroendocrine tumors is planned. Radiopharmaceuticals based on glucagon-like peptide 1 (GLP1) or minigastrins are in the early evaluation stage for application in the treatment of insulinomas and medullary thyroid cancer. In general, radiopharmaceutical therapy belongs to the group of so-called theranostics which means that therapy is tailored for individual patients based on molecular imaging diagnostics to stratify target positive or target negative tumor phenotypes.

    Postcancer fatigue is a frequently occurring problem, impairing quality of life. Little is known about (neuro)physiological factors determining postcancer fatigue. It may be hypothesized that postcancer fatigue is characterized by low peripheral muscle fatigue and high central muscle fatigue. The aims of this study were to examine whether central and peripheral muscle fatigue differ between fatigued and non-fatigued cancer survivors and to examine the effect of cognitive behavioral therapy (CBT) on peripheral and central muscle fatigue of fatigued cancer survivors in a randomized controlled trial. Sixteen fatigued patients in the intervention group (CBT) and eight fatigued patients in the waiting list group were successfully assessed at baseline and six months later. Baseline measurements of 20 fatigued patients were compared with 20 non-fatigued patients. A twitch interpolation technique and surface electromyography were applied, respectively, during sustained contraction of the biceps brachii muscle. Muscle fiber conduction velocity (MFCV) and central activation failure (CAF) were not significantly different between fatigued and non-fatigued patients. Change scores of MFCV and CAF were not significantly different between patients in the CBT and waiting list groups. Patients in the CBT group reported a significantly larger decrease in fatigue scores than patients in the waiting list group. Postcancer fatigue is neither characterized by abnormally high central muscle fatigue nor by low peripheral muscle fatigue. These findings suggest a difference in the underlying physiological mechanism of postcancer fatigue vs. other fatigue syndromes. Copyright © 2015 American Academy of Hospice and Palliative Medicine.

    Rigorously applied exercise interventions undertaken in a research setting result in improved health-related quality of life (hrqol) in cancer survivors, but research to demonstrate effective translation of that research to practice is needed. The objective of the present study was to determine the effect of fee-for-service cancer rehabilitation programs in the community on hrqol and on self-reported physical activity and its correlates. After enrolment and 17 ± 4 weeks later, new clients (n = 48) to two fee-for-service cancer rehabilitation programs completed the 36-Item Short Form Health Survey (rand-36: rand Corporation, Santa Monica, CA, U.S.A.), the Godin Leisure-Time Exercise Questionnaire, and questions about physical activity correlates. Normal fee-for-service operations were maintained, including a fitness assessment and individualized exercise programs supervised in a group or one-on-one setting, with no minimum attendance required. Fees were associated with the assessment and with each exercise session. Of the 48 participants, 36 (75%) completed both questionnaires. Improvements in the physical functioning, role physical, pain, and energy/fatigue scales on the rand-36 exceeded minimally important differences and were of a magnitude similar to improvements reported in structured, rigorously applied, and free research interventions. Self-reported levels of vigorous-intensity (p = 0.021), but not moderate-intensity (p = 0.831) physical activity increased. The number of perceived barriers to exercise (p = 0.035) and the prevalence of fatigue as a barrier (p = 0.003) decreased. Exercise self-efficacy improved only in participants who attended 11 or more sessions (p = 0.002). Exercise enjoyment did not change (p = 0.629). Enrolment in fee-for-service cancer rehabilitation programs results in meaningful improvements in hrqol comparable to those reported by research interventions, among other benefits. The fee-for-service model could be an effective model for

    Chronic or persistent fatigue is a common, debilitating symptom of several diseases. Persistent fatigue has been associated with low-grade inflammation in several models of fatigue, including cancer-related fatigue and chronic fatigue syndrome. However, it is unclear how low-grade inflammation leads to the experience of fatigue. We here propose a model of an imbalance in energy availability and energy expenditure as a consequence of low-grade inflammation. In this narrative review, we discuss how chronic low-grade inflammation can lead to reduced cellular-energy availability. Low-grade inflammation induces a metabolic switch from energy-efficient oxidative phosphorylation to fast-acting, but less efficient, aerobic glycolytic energy production; increases reactive oxygen species; and reduces insulin sensitivity. These effects result in reduced glucose availability and, thereby, reduced cellular energy. In addition, emerging evidence suggests that chronic low-grade inflammation is associated with increased willingness to exert effort under specific circumstances. Circadian-rhythm changes and sleep disturbances might mediate the effects of inflammation on cellular-energy availability and non-adaptive energy expenditure. In the second part of the review, we present evidence for these metabolic pathways in models of persistent fatigue, focusing on chronic fatigue syndrome and cancer-related fatigue. Most evidence for reduced cellular-energy availability in relation to fatigue comes from studies on chronic fatigue syndrome. While the mechanistic evidence from the cancer-related fatigue literature is still limited, the sparse results point to reduced cellular-energy availability as well. There is also mounting evidence that behavioral-energy expenditure exceeds the reduced cellular-energy availability in patients with persistent fatigue. This suggests that an inability to adjust energy expenditure to available resources might be one mechanism underlying persistent fatigue.

    Low testosterone levels in men are associated with fatigue, limited physical performance and reduced health-related quality of life (HRQOL); however, this relationship has never been assessed in patients with anti-neutrophil cytoplasmic antibodies (ANCA) -associated vasculitides (AAV). The aim of this study was to assess the prevalence of androgen deficiency and to investigate the role of testosterone in fatigue, limited physical condition and reduced HRQOL in men with AAV. Male patients with AAV in remission were included in this study. Fatigue and HRQOL were assessed by the multi-dimensional fatigue inventory (MFI)-20 and RAND-36 questionnaires. Seventy male patients with a mean age of 59 years (SD 12) were included. Scores of almost all subscales of both questionnaires were significantly worse in patients compared to controls. Mean total testosterone and free testosterone levels were 13.8 nmol/L (SD 5.6) and 256 pmol/L (SD 102), respectively. Androgen deficiency (defined according to Endocrine Society Clinical Practice Guidelines) was present in 47% of patients. Scores in the subscales of general health perception, physical functioning and reduced activity were significantly worse in patients with androgen deficiency compared to patients with normal androgen levels. Testosterone and age were predictors for the RAND-36 physical component summary in multiple linear regression analysis. Testosterone, age, vasculitis damage index (VDI) and C-reactive protein (CRP) were associated with the MFI-20 subscale of general fatigue. This study showed that androgen deficiency was present in a substantial number of patients with AAV. Testosterone was one of the predictors for physical functioning and fatigue. Testosterone may play a role in fatigue, reduced physical performance and HRQOL in male patients with AAV.

    Full Text Available The objective of this study was to evaluate the independent associations between nausea, vomiting, fatigue and health-related quality of life of women in early pregnancy in the Generation R study, which is a prospective mother and child cohort. Analyses were based on 5079 women in early pregnancy in the Rotterdam area, the Netherlands. The information on nausea, vomiting and fatigue in the previous three months was measured in the questionnaire at enrollment, as well as potential confounders (i.e., maternal/gestational age, ethnic background, educational level, parity, marital status, body mass index, tobacco and alcohol use, chronic/infectious conditions, uro-genital conditions/symptoms, sleep quality, headache, anxiety, and depression. Health-related quality of life was assessed by the 12-item Short Form Health Survey and physical and mental component summary scores were calculated. Multivariate regression models were performed to evaluate the independent associations of the presence of nausea, vomiting and fatigue with health-related quality of life, adjusting for potential confounders. 33.6% of women experienced daily presence of nausea, 9.6% for vomiting and 44.4% for fatigue. Comparing with women who never reported nausea, vomiting and fatigue, women with daily presence of at least one of these symptoms had significantly lower scores of physical component summary and mental component summary, after adjusting for potential confounders. Our study shows how common nausea, vomiting and fatigue are among women in early pregnancy and how much each of these symptoms negatively impact on health-related quality of life. We call for awareness of this issue from health care professionals, pregnant women and their families.

    Little is known about rehabilitation for postthoracotomy non-small cell lung cancer (NSCLC) patients. This research uses a perceived self-efficacy-enhancing light-intensity exercise intervention targeting a priority symptom, cancer-related fatigue (CRF), for postthoracotomy NSCLC patients. This article reports on phase II of a 2-phase study. Phase I focused on initiation and tolerance of exercise during the 6 weeks immediately after thoracotomy, whereas phase II addressed maintenance of exercise for an additional 10 weeks including participants initiating and completing chemotherapy and/or radiation therapy. The objective of this study was to investigate the feasibility, acceptability, and preliminary efficacy of an exercise intervention for postthoracotomy NSCLC patients to include those initiating and completing adjuvant therapy. A single-arm design composed of 7 participants postthoracotomy for NSCLC performed light-intensity exercises using an efficacy-enhancing virtual-reality approach using the Nintendo Wii Fit Plus. Despite most participants undergoing chemotherapy and/or radiation therapy, participants adhered to the intervention at a rate of 88% with no adverse events while giving the intervention high acceptability scores on conclusion. Likewise, participants' CRF scores improved from initiation through the conclusion of the intervention with perceived self-efficacy for walking at a light intensity continuously for 60 minutes, improving significantly upon conclusion over presurgery values. Postthoracotomy NSCLC patients maintained exercise for an additional 10 weeks while undergoing adjuvant therapy showing rehabilitation potential because the exercise intervention was feasible, safe, well tolerated, and highly acceptable showing positive changes in CRF self-management. A randomized controlled trial is needed to further investigate these relationships.

    Many patients near death report an interest in knowing their prognoses. Patients' awareness of disease status may lead to more appropriate care and maintained or improved quality of life. However, it is not known whether advanced cancer patients' awareness of disease status is associated with patients' quality of life. We aimed to examine the effect of patients' awareness of disease status on the health-related quality of life (HRQOL) among advanced cancer patients undergoing palliative chemotherapy. In this prospective cohort study, patients were followed-up at 4-6 weeks and 2-3 months after the initial palliative chemotherapy. Patients' awareness of disease status, and demographic and clinical characteristics were assessed at baseline, and depression and anxiety using the Hospital Anxiety and Depression Scale (HADS) and HRQOL using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) were assessed three times. In total, 100 patients with advanced cancer starting palliative chemotherapy were recruited from two tertiary university hospitals and from the Korea National Cancer Center. Patients with advanced cancer undergoing palliative chemotherapy experienced deteriorated HRQOL. Of these, the patients who were aware of their disease status as incurable had significantly higher role (p=0.002), emotional (p=0.025), and social functioning (p=0.002), and lower fatigue (p=0.008), appetite loss (p=0.039), constipation (p=0.032), financial difficulties (p=0.019), and anxiety (p=0.041) compared with patients unaware of disease status. Our findings demonstrate the importance of patients' awareness of disease status to HRQOL.

    Real-time driver monitoring systems represent a solution to address key behavioral risks as they occur, particularly distraction and fatigue. The efficacy of these systems in real-world settings is largely unknown. This article has three objectives: (1) to document the incidence and duration of fatigue in real-world commercial truck-driving operations, (2) to determine the reduction, if any, in the incidence of fatigue episodes associated with providing feedback, and (3) to tease apart the relative contribution of in-cab warnings from 24/7 monitoring and feedback to employers. Data collected from a commercially available in-vehicle camera-based driver monitoring system installed in a commercial truck fleet operating in Australia were analyzed. The real-time driver monitoring system makes continuous assessments of driver drowsiness based on eyelid position and other factors. Data were collected in a baseline period where no feedback was provided to drivers. Real-time feedback to drivers then occurred via in-cab auditory and haptic warnings, which were further enhanced by direct feedback by company management when fatigue events were detected by external 24/7 monitors. Fatigue incidence rates and their timing of occurrence across the three time periods were compared. Relative to no feedback being provided to drivers when fatigue events were detected, in-cab warnings resulted in a 66% reduction in fatigue events, with a 95% reduction achieved by the real-time provision of direct feedback in addition to in-cab warnings (p safety culture of the company in terms of how the information is used. Data were analysed on a per-truck trip basis, and the findings are indicative of fatigue events in a large-scale commercial transport fleet.

Evidence that real-time driver monitoring feedback is effective in reducing fatigue events is

    Fatigue is one of the most common and debilitating side effects of cancer and cancer treatment, and yet its etiology remains elusive. The goal of this study is to understand the role of chronic inflammation in fatigue following repeated stress from radiotherapy. Fatigue and non-fatigue categories were assessed using ≥ 3-point change in Functional Assessment of Cancer Therapy-Fatigue questionnaire (FACT-F) administered to participants at baseline/before radiotherapy and one year post-radiotherapy. Whole genome microarray and cytokine multiplex panel were used to examine fatigue-related transcriptome and serum cytokine changes, respectively. The study included 86 subjects (discovery phase n = 40, validation phase n = 46). The sample in the discovery phase included men with prostate cancer scheduled to receive external-beam radiotherapy. A panel of 48 cytokines were measured and the significantly changed cytokine found in the discovery phase was validated using sera from a separate cohort of men two years after completing radiotherapy for prostate cancer at a different institution. Effects of the significantly changed cytokine on cell viability was quantified using the MTT assay. During the discovery phase, tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and TRAIL decoy receptor, TNFRSF10C (TRAIL-R3), were significantly upregulated in fatigued (≥3-point decrease from baseline to 1yr-post radiotherapy) subjects (n = 15). In the validation phase, TRAIL correlated with fatigue scores 2yrs post-radiotherapy. TRAIL caused selective cytotoxicity in neuronal cells, but not in microglial and muscle cells, in vitro. Late-onset inflammation directed by TRAIL may play a role in fatigue pathogenesis post-repeated stress from irradiation. Published by Elsevier Ltd.

    Full Text Available The purpose of the present paper was to evaluate the effects of an 8-week multimodal program focused on core stability exercises and recovery massage with DVD support for a 6-month period in physical and psychological outcomes in breast cancer survivors. A randomized controlled clinical trial was performed. Seventy-eight (n=78 breast cancer survivors were assigned to experimental (core stability exercises plus massage-myofascial release and control (usual health care groups. The intervention period was 8 weeks. Mood state, fatigue, trunk curl endurance, and leg strength were determined at baseline, after the last treatment session, and at 6 months of followup. Immediately after treatment and at 6 months, fatigue, mood state, trunk curl endurance, and leg strength exhibited greater improvement within the experimental group compared to placebo group. This paper showed that a multimodal program focused on core stability exercises and massage reduced fatigue, tension, depression, and improved vigor and muscle strength after intervention and 6 months after discharge.

    Sexual dysfunction is a known complication of adjuvant therapy for breast cancer and an important determinant of quality of life. However, few studies have explored how treatment and other factors affect sexual functioning in young breast cancer survivors. Four hundred sixty-one premenopausal women with stage 0 through III breast cancer were surveyed an average of 1 year after diagnosis as part of a prospective cohort study of women who were aged ≤40 years at diagnosis. Sexual interest and dysfunction were assessed using the Cancer Rehabilitation Evaluation System (CARES). Mean CARES scores were compared and multiple regression models were fit to assess treatment and a range of menopausal and somatic symptoms in relation to sexual functioning. Mean CARES sexual interest and dysfunction scores were both highest (indicating poorer functioning) among women who received chemotherapy and were amenorrheic from treatment. After accounting for menopausal and somatic symptoms, treatment-associated amenorrhea remained associated with decreased interest but was no longer an independent predictor of dysfunction. In the multivariable analysis, independent predictors of dysfunction included vaginal pain symptoms, poorer body image, and fatigue. Sexual interest was associated with vaginal pain symptoms, body image, and weight problems. Factors associated with decreased sexual functioning in young breast cancer survivors can often be ameliorated. The current findings have implications for premenopausal women with other types of cancer who might be experiencing amenorrhea because of chemotherapy or surgery. Increased awareness and early intervention is essential to help improve sexual functioning and associated quality of life for all young cancer survivors. © 2014 American Cancer Society.

    Full Text Available Cancer treatment for elderly patients is often complicated by poor physical condition, impaired functioning and comorbidities. Patient reported health related quality of life (HRQOL can contribute to decisions about treatment goals and supportive therapy. Knowledge about factors influencing HRQOL is therefore needed for the development of supportive measures and care pathways. An exploratory secondary data analysis on 518 assessments of the European Organisation for Research and Treatment of Cancer (EORTC core questionnaire (EORTC QLQ-C30 and the elderly module (EORTC QLQ-ELD14 was performed to identify factors predictive for global HRQOL. Preliminary simple and multivariable regression analyses were conducted resulting in a final model comprising sociodemographic and disease specific variables and scales of the QLQ-C30 and QLQ-ELD14. Age, sex and disease related variables explained only part of the variance of global HRQOL (adjusted R2 = 0.203. In the final model (adjusted R2 = 0.504 fatigue, social function, burden of illness and joint stiffness showed possible influence on global HRQOL. Fatigue, social function and burden of illness seem to have the largest impact on global HRQOL of elderly cancer patients. Further prospective studies should examine these domains. Actionable symptoms should be given special attention to initiate targeted supportive measures aiming to maximize HRQOL of older cancer patients.

Participants (N = 14) described three distinct domains: tiredness, fatigue, and exhaustion. Most participants experienced tiredness prior to diagnosis, fatigue during daily life, and exhaustion after overexertion. We also discuss participants' ability to adapt to a variety of stressors and prevent shifts to exhaustion, and relate our findings to stress theory and other current research. Primary strategies that promoted adaptation to stressors included pacing and extended rest periods. These findings can aid health care professionals in detecting impending shifts between tiredness, fatigue, and exhaustion and in improving adaptive strategies, thereby improving quality of life. © The Author(s) 2015.

    The treatment of primary breast cancer usually consists of surgery often followed by adjuvant therapy (radiotherapy, chemotherapy, hormonal treatment, etc.) to reduce the risk of recurrence. The cancer diagnosis and the treatments may have significant impact on the patients' quality of life. This thesis deals with scientific aspects and clinical results of a study aimed at assessing the impact of breast cancer (and its treatment) on the patients' quality of life. Studies such as this assessing the problems and symptoms experienced by the patients are often referred to as health-related quality of life (HRQL) research. HRQL research deals with subjective experiences and raises challenging, scientific questions. Therefore, much attention was directed towards methodological issues in this clinically motivated project. The study was a prospective, longitudinal, questionnaire-based investigation of women with newly diagnosed breast cancer registered in the Danish Breast Cancer Co-operative Group's DBCG 89 Program. The patients were sub-divided into low-risk and high-risk patients. High-risk patients were offered randomisation in one of three randomised adjuvant therapy trials involving chemotherapy, ovarian ablation, and endocrine therapy. After a literature study and interviews with breast cancer patients, a questionnaire was composed that included two widely used standard questionnaires (EORTC QLQ-C30 and Hospital Anxiety and Depression (HAD) Scale) and a DBCG 89 Questionnaire developed for this study. A total of 1,898 eligible patients were invited by post to participate in the study involving six assessments over a 2-year period, and 1,713 patients (90%) completed the first questionnaire. Furthermore, a questionnaire was sent to 872 women selected at random from the general population; 608 (70%) responded. The multi-item scales of the two standard questionnaires were analysed for so-called differential item functioning (DIF) in order to investigate whether the

    Cognitive behavioural models of chronic fatigue syndrome (CFS) propose that attention processes, specifically, enhanced selective attention to health-threat related cues, may play an important role in symptom maintenance. The current study investigated attentional bias towards health-threat stimuli in CFS. It also examined whether individuals with CFS have impaired executive attention, and whether this was related to attentional bias. 27 participants with CFS and 35 healthy controls completed a Visual Probe Task measuring attentional bias, and an Attention Network Test measuring executive attention, alerting and orienting. Participants also completed self-report measures of CFS and mood symptoms. Compared to the control group, the CFS group showed greater attentional bias for health-threat words than pictures; and the CFS group was significantly impaired in executive attention. Furthermore, CFS individuals with poor executive attention showed greater attentional bias to health-threat related words, compared not only to controls but also to CFS individuals with good executive attention. Thus, this study revealed a significant relationship between attentional bias and executive attention in CFS: attentional bias to threat was primarily evident in those with impaired executive attention control. Taking account of individual differences in executive attention control in current intervention models may be beneficial for CFS. Copyright © 2013 Elsevier Ltd. All rights reserved.

    International evidence-based guidelines recommend physical exercise to form part of standard care for all cancer survivors. However, at present, the optimum exercise intensity is unclear. Therefore, we aimed to evaluate the effectiveness of a high intensity (HI) and low-to-moderate intensity (LMI) resistance and endurance exercise program compared with a wait list control (WLC) group on physical fitness and fatigue in a mixed group of cancer survivors who completed primary cancer treatment, including chemotherapy. Overall, 277 cancer survivors were randomized to 12 weeks of HI exercise (n = 91), LMI exercise (n = 95), or WLC (n = 91). Both interventions were identical with respect to exercise type, duration and frequency, and only differed in intensity. Measurements were performed at baseline (4-6 weeks after primary treatment) and post-intervention. The primary outcomes were cardiorespiratory fitness (peakVO2), muscle strength (grip strength and 30-second chair-stand test), and self-reported fatigue (Multidimensional Fatigue Inventory; MFI). Secondary outcomes included health-related quality of life, physical activity, daily functioning, body composition, mood, and sleep disturbances. Multilevel linear regression analyses were performed to estimate intervention effects using an intention-to-treat principle. In the HI and LMI groups, 74 % and 70 % of the participants attended more than 80 % of the prescribed exercise sessions, respectively (P = 0.53). HI (β = 2.2; 95 % CI, 1.2-3.1) and LMI (β = 1.3; 95 % CI, 0.3-2.3) exercise showed significantly larger improvements in peakVO2 compared to WLC. Improvements in peakVO2 were larger for HI than LMI exercise (β = 0.9; 95 % CI, -0.1 to 1.9), but the difference was not statistically significant (P = 0.08). No intervention effects were found for grip strength and the 30-second chair-stand test. HI and LMI exercise significantly reduced general and physical fatigue and reduced activity

    Full Text Available Objective. To investigate the effects of bright light treatment for secondary outcome measures and to explore and validate empirically derived subgroups and treatment effects in subgroups. Methods. A descriptive design. A sample of forty-nine persons (mean age of 45.8 with clinically assessed seasonal affective disorder (SAD or subsyndromal SAD (S-SAD participated in a two-group clinical trial evaluating the effects of treatment with bright light therapy. A person-oriented cluster analysis was applied to study treatment effects in subgroups. Results. For the merged group, sleepiness (Epworth Sleepiness Scale, fatigue (fatigue questionnaire, and health-related quality of life (SF-36 were improved at posttreatment, and results were maintained at the one-month followup. Three distinct subgroups had a high level of fatigue in common, while the level of excessive daytime sleepiness and depressed mood differed between the subgroups. Over time, all subgroups improved following ten days treatment in a light room. Conclusion. Fatigue, excessive daytime sleepiness, and health-related quality of life improve in a similar way as depressed mood following treatment with bright light. The treatment was effective irrespective of the severity of the disorder, that is, for persons with SAD and subsyndromal SAD.

    The aim of this study was to evaluate the effects of an mHealth intervention (intervention using mobile technology) consisting of tailored advice regarding exposure to daylight, sleep, physical activity, and nutrition, and aiming to improve health-related behavior, thereby reducing sleep problems and fatigue and improving health perception of airline pilots. A randomized controlled trial was conducted among 502 airline pilots. The intervention group was given access to both the MORE Energy mobile application (app) with tailored advice and a website with background information. The control group was directed to a website with standard information about fatigue. Health-related behavior, fatigue, sleep, and health perception outcomes were measured through online questionnaires at baseline and at three and six months after baseline. The effectiveness of the intervention was determined using linear and Poisson mixed model analyses. After six months, compared to the control group, the intervention group showed a significant improvement on fatigue (β= -3.76, P<0.001), sleep quality (β= -0.59, P=0.007), strenuous physical activity (β=0.17, P=0.028), and snacking behavior (β= -0.81, P<0.001). No significant effects were found for other outcome measures. The MORE Energy mHealth intervention reduced self-reported fatigue compared to a minimal intervention. Some aspects of health-related behavior (physical activity and snacking behavior) and sleep (sleep quality) improved as well, but most did not. The results show offering tailored advice through an mHealth intervention is an effective means to support employees who have to cope with irregular flight schedules and circadian disruption. This kind of intervention might therefore also be beneficial for other working populations with irregular working hours.

    2008-01-01

    The present review addresses mechanisms of importance for hyperthermia-induced fatigue during short intense activities and prolonged exercise in the heat. Inferior performance during physical activities with intensities that elicit maximal oxygen uptake is to a large extent related to perturbation...... of the cardiovascular function, which eventually reduces arterial oxygen delivery to the exercising muscles. Accordingly, aerobic energy turnover is impaired and anaerobic metabolism provokes peripheral fatigue. In contrast, metabolic disturbances of muscle homeostasis are less important during prolonged exercise...... in the heat, because increased oxygen extraction compensates for the reduction in systemic blood flow. The decrease in endurance seems to involve changes in the function of the central nervous system (CNS) that lead to fatigue. The CNS fatigue appears to be influenced by neurotransmitter activity...

    The purpose of the present article was to investigate the health related quality of life (QoL) of young women with breast cancer. For the purposes of this article, we reviewed the literature via the electronic databases Pubmed, Scopus and Google Scholar. Key words used were breast cancer, young women, health related quality of life, and quality of life. Young women reported fatigue, pain in the breast and hand problems with lymphedema as the most frequent physical effects of treatment. Other physical problems were the not periodic and painful menses, vaginal dryness and loss of libido. Many young women had depressive symptoms such as depressed mood, helplessness, hopelessness, sleep loss, psychomotor retardation and disorders of appetite. There were often concerns about the health monitoring and self-image, while they were anxious if they will have a baby in the future or if they can nurture the existing ones. Many problems arose in the career of young women. They faced discrimination in the labor supply and/or layoff because they were considered unable to do their job effectively. In addition, they reported isolation problems and feeling different from other women of similar age. Young women consider that their healthrelated QoL is worse compared with older women. Young women worry about their future, with particular reference to their role as mothers and especially to children-bearing. The free screening and non-exclusion of young women is particularly important for breast cancer prevention and women's well-being.

  3. FUTSAL MATCH-RELATED FATIGUE AFFECTS RUNNING PERFORMANCE AND NEUROMUSCULAR PARAMETERS BUT NOT FINISHING KICK SPEED OR ACCURACY

    2016-11-01

    Full Text Available Purpose: The aim of the present study was to investigate the influence of futsal match-related fatigue on running performance, neuromuscular variables, and finishing kick speed and accuracy. Methods: Ten professional futsal players participated in the study (age: 22.2±2.5 years; and initially performed an incremental protocol to determine maximum oxygen uptake (VO2max : 50.6±4.9 mL.kg-1.min-1. Next, simulated games were performed, in four periods of 10 min during which heart rate and blood lactate concentration were monitored. The entire games were video recorded for subsequent automatic tracking. Before and immediately after the simulated game, neuromuscular function was measured by maximal isometric force of knee extension, voluntary activation using twitch interpolation technique, and electromyographic activity. Before, at half time, and immediately after the simulated game, the athletes also performed a set of finishing kicks for ball speed and accuracy measurements. Results: Total distance covered (1st half: 1986.6±74.4 m; 2nd half: 1856.0±129.7 m – P=0.00 and distance covered per minute (1st half: 103.2±4.4 m.min-1; 2nd half: 96.4±7.5 m.min-1 – P=0.00 demonstrated significant declines during the simulated game, as well as maximal isometric force of knee extension (Before: 840.2±66.2 N; After: 751.6±114.3 N – P=0.04 and voluntary activation (Before: 85.9±7.5%; After: 74.1±12.3% – P=0.04, however ball speed and accuracy during the finishing kicks were not significantly affected.Conclusion: Therefore, we conclude that despite the decline in running performance and neuromuscular variables presenting an important manifestation of central fatigue, this condition apparently does not affect the speed and accuracy of finishing kicks.

    The aim of the present study was to investigate the impact of lifetime potentially traumatic events, including losses, and of post-traumatic stress symptoms on the severity of illness and health-related quality of life in patients with fibromyalgia (FM). Seventy patients with FM, diagnosed according to the American College of Rheumatology criteria, were consecutively enrolled at the Unit of Rheumatology of the University of Pisa, Italy. Assessments included: SCID-I/P; the Fibromyalgia Impact Questionnaire (FIQ) and the Medical Outcomes Study Short Form-36 Health Survey (MOS SF-36), for the severity of pain; the Health-Related Quality of Life (HRQoL); the Trauma and Loss Spectrum Self-Report (TALS-SR) life-time version. The FIQ total score was related to the number of loss events (Domain I) and to symptoms of grief reactions (Domain II) and re-experiencing (Domain V) of the TALS-SR. The 'VAS fatigue' scores (FIQ) were significantly related to the TALS-SR symptoms of grief reactions (Domain II) and re-experiencing (Domain V). The Mental Component Summary and Bodily Pain scores of the MOS SF-36 were significantly related to all TALS-SR domains, the latter with the exception of the VIII (Arousal). Our results corroborate the presence of a relationship between the lifetime exposure to potentially traumatic events, in particular loss events, and lifetime post-traumatic stress symptoms and the severity of illness and HRQoL in patients with FM.

    Multiple sclerosis is associated with immune system dysfunction and chronic inflammation; however, possible relations between immunologic and metabolic factors and some psychological indexes such as fatigue and quality of life, especially in relation to exercise training, have not yet been investigated. The present study was designed to investigate the effect of aerobic interval training on interleukin-10/tumor necrosis factor ratio and adipokine (leptin and adiponectin) concentrations in women with multiple sclerosis. Furthermore, the relationship between these factors with fatigue and quality of life were assessed. Forty women with multiple sclerosis (Expanded Disability Status Scale ≤3) were randomized into either a non-exercising control or training group. The training group performed 8-weeks of upper and lower limb aerobic interval training. Serum concentrations of tumor necrosis factorα, interleukin-10, leptin, and adiponectin were measured before and after the 8-week intervention. Moreover, antropometric measures and measures for fatigue and quality of life were determined at the onset of and after exercise training. The results revealed that leptin and tumor necrosis factorα levels significantly decreased subsequent to the aerobic interval training. Although blood adiponectin levels considerably increased in the training group, interleukin-10 and interleukin-10/tumor necrosis factorα ratio underwent no substantial change after the exercise training. In addition, the aerobic interval training was associated with improvement in fatigue, quality of life, and maximal oxygen consumption. Our findings suggested that aerobic interval training can be an effective strategy for managing the immune system at least by its significant impact on inflammatory cytokines and adipokines levels in women with multiple sclerosis. Additionally, this positive impact improved fatigue and adipose tissue indicators.

    The objective with this study was to explore satisfaction with life (SWL) among adults with Marfan syndrome (MFS) compared to the general Norwegian population and other patient groups and further to examine the associations between SWL and demographic factors, contact with social and health services, MFS-related health problems, chronic pain, and fatigue. This is a cross-sectional study with postal questionnaire, including the Satisfaction with Life Scale (SWLS), questions on demographic factors, health-related aspects of MFS, and validated instruments measuring chronic pain (Standardized Nordic Questionnaire) and fatigue (Fatigue Severity Scale). One hundred and seventeen adults with MFS were invited to participate, and 73 (62 %) participated. The SWLS mean score in adults with MFS was significantly lower than that reported for the general Norwegian population, but similar to or higher than that reported for other patient groups. Only fatigue, aortic dissection, and having regular contact with psychologist showed significant unique contribution to the SWLS score in the hierarchical multiple linear analyses. The total variance explained by the model was 45.2 % p ≤ 0.000, confirming that the combination of independent variables significantly predicted SWLS. The results reflect that MFS influences people's SWL and that particularly severe fatigue, aortic dissection, and psychological aspects are associated with lower SWL. This is important to take into account in the clinical work with people with MFS. Further investigation is needed, especially on larger sample groups. Studies with combination of qualitative and quantitative approaches are recommended to obtain more comprehensive and accurate knowledge about the consequences of MFS on satisfaction with life.

    Familial aggregation of testicular cancer has been reported consistently, but it is less clear if there is any association between risk of testicular cancer and other cancers in the family. We conducted a population based case-control study to examine the relationship between risk of testicular cancer and 22 different cancers in first-degree relatives. We included 3297 cases of testicular cancer notified to the Danish Cancer Registry between 1991 and 2003. 6594 matched controls were selected from the Danish Civil Registration System, which also provided the identity of 40,104 first-degree relatives of case and controls. Familial cancer was identified by linkage to the Danish Cancer Registry, and we used conditional logistic regression to analyse whether cancer among first-degree relatives was associated with higher risk of testicular cancer. Rate ratio (RR) for testicular cancer was 4.63 (95% CI: 2.41–8.87) when a father, 8.30(95% CI: 3.81–18.10) when a brother and 5.23 (95% CI: 1.35–20.26) when a son had testicular cancer compared with no familial testicular cancer. Results were similar when analyses were stratified by histologic subtypes of testicular cancer. Familial Non-Hodgkin lymphoma and oesophageal cancer were associated with testicular cancer; however these may be chance findings. The familial aggregation of testicular and possibly other cancers may be explained by shared genes and/or shared environmental factors, but the mutual importance of each of these is difficult to determine.

    Full Text Available Abstract Background Polyethylene wear is an important factor for longevity of total knee arthroplasty. Proven and suspicious factors causing wear can be grouped as material, patient and surgery related. There are more studies correlating design and/or biomaterial factors to in vivo wear than those to patient and surgery related factors. Many retrieval studies just include revision implants and therefore may not be representative. This study is aimed to correlate patient- and surgery- related factors to visual wear score by minimizing design influence and include both autopsy and revision implants. Comparison between the groups was expected to unmask patient and surgery-related factors responsible for wear. Methods The amount of joint side wear on polyethylene retrievals was measured using a modification of an established visual wear score. Fatigue type wear was defined as summation of the most severe wear modes of delamination, pitting and cracks. Analysis of patient and surgery related variables suspicious to cause wear included prospectively sampled patient activity which was measured by self reported walking capacity. Statistical analysis was done by univariate analysis of variance. Activity level and implantation time were merged to an index of use and correlated to the wear score. Results Wear score after comparable implantation time was significantly less in the autopsy group. Even so, fatigue type wear accounted for 84 and 93 % of total wear score on autopsy and revision implants respectively. A highly significant influence on wear score was found in time of implantation (p = 0.002, level of activity (p = 0.025 and inserts belonging to revision group (p = 0.006. No influence was found for the kind of patella replacement (p = 0.483. Body mass index and accuracy of component alignment had no significant influence on visual wear score. Fatigue-type wear in the medial compartment was closely correlated to the index of use in the autopsy (R2

    Full Text Available Anthropometry is a science of human body measurement that could be used for manufacturing artificial limbs or prosthesis, investigating body differences between populations, utilizing in forensics and criminology, or even in the diagnosis of some diseases. Two of the most important anthropometric characteristics are dermatoglyphic patterns and finger length. Many studies have evaluated the relation between these two characteristics in different diseases such as cancers. It assumed that dermatoglyphic patterns and finger length could be used as predictors of some cancers such as gastric, ovarian, prostate, testicular, and breast cancers. In this review, we evaluated the relation between dermatoglyphic variability and finger length in different cancers more precisely.

    Although smoking-related diseases, such as chronic obstructive pulmonary disease (COPD), are often accompanied by increased peripheral muscle fatigability, the extent to which this is a feature of the disease or a direct effect of smoking per se is not known. Skeletal muscle function was investigated in terms of maximal voluntary isometric torque, activation, contractile properties and fatigability, using electrically evoked contractions of the quadriceps muscle of 40 smokers [19 men and 21 w...

    Full Text Available Considering the importance of the road transportation nowadays, concerns related to pavement deterioration and maintenance have become relevant subjects. Especially for commercial vehicles, the vertical dynamic load (characterized by the tire-road interaction is directly related to wear on the road surface. Given this, the main objective of this paper is to analyse effects of vertical loads applied on the flexible pavement, considering the variation of the condition of shock absorbers from a truck's front suspension. The measurements were performed on a rigid truck, with 2 steering front axles, in a durability test track located in Brazil. With a constant load of 6 tons on the front suspension (the maximum allowed load on front axles according to Brazilian legislation, 3 different shock absorber conditions were evaluated: new, used and failed. By applying the relative damage concept, it is possible to conclude that the variation of the shock absorber conditions will significantly affect the vertical load applied on the pavement. Although the results clearly point to a dependent relationship between the load and the condition of the shock absorbers, it is recommended to repeat the same methodology, in future to analyse the influence of other quarter car model variants (such as spring rate, mass and tire spring stiffness.

    Chemotherapy (CT) is the first priority treatment for advanced stage lung cancer. However, symptom distress, impaired ability to conduct daily activities, and post-CT care needs are potential side effects of CT. To explore the factors related to the care needs of post-chemotherapy lung cancer patients. A cross-sectional study was used. One hundred and twenty-one adult patients who had been diagnosed with advanced-stage lung cancer and who had undergone CT using the Platinum and Docetaxel doublet regimen were recruited from a medical center in southern Taiwan. The instruments used included a nursing care needs survey, symptoms distress scale, daily activity interference scale, and patient characteristics datasheet. Participants self-prioritized their emergency management, health consultation, and emotional support activities based on their perceived care needs. The top three post-CT symptoms in terms of severity were: fatigue, appetite change, and sleep disorder. Primary disruptions in daily activities during the post-CT period related to: holding social activities, work, and stair climbing. Significant and positive correlations were found among daily activity interference (r = .30, p needs. The regression model indicated daily activity interference as a predictor of care needs, accounting for 10.7% of the total variance. These results highlight the relationships among care needs, symptom distress, and daily activity interference in post-chemotherapy lung-cancer patients. The present study provides a reference for nursing care to reduce the symptom distress, to enhance the performance of daily activities, and to meet the care needs of lung-cancer patients.

    In recent years, cancer case counts in the U.S. underwent a large, rapid decline-an unexpected change given population growth for older persons at highest cancer risk. As these declines coincided with the Great Recession, we examined whether they were related to economic conditions. Using California Cancer Registry data from California's 30 most populous counties, we analyzed trends in cancer incidence during pre-recession (1996-2007) and recession/recovery (2008-2012) periods for all cancers combined and the ten most common sites. We evaluated the recession's association with rates using a multifactorial index that measured recession impact, and modeled associations between case counts and county-level unemployment rates using Poisson regression. Yearly cancer incidence rate declines were greater during the recession/recovery (3.3% among males, 1.4% among females) than before (0.7 and 0.5%, respectively), particularly for prostate, lung, and colorectal cancers. Lower case counts, especially for prostate and liver cancer among males and breast cancer, melanoma, and ovarian cancer among females, were associated with higher unemployment rates, irrespective of time period, but independent of secular effects. The associations for melanoma translated up to a 3.6% decrease in cases with each 1% increase in unemployment. Incidence declines were not greater in counties with higher recession impact index. Although recent declines in incidence of certain cancers are not differentially impacted by economic conditions related to the Great Recession relative to pre-recession conditions, the large recent absolute declines in the case counts of some cancer may be attributable to the large declines in unemployment in the recessionary period. This may occur through decreased engagement in preventive health behaviors, particularly for clinically less urgent cancers. Continued monitoring of trends is important to detect any rises in incidence rates as deferred diagnoses come to

    Palliative cancer care in Greenland is provided by health professionals at local level, the national Queen Ingrid's Hospital and at Rigshospitalet in Denmark. To improve and develop care for relatives of patients with advanced cancer, we conducted a mixed method study examining relatives' level...... of satisfaction with care and treatment and their current main concerns. The aim was to investigate relatives' level of satisfaction with advanced cancer care and bring to light their current main concerns. The FAMCARE-20 questionnaire was translated to Greenlandic and pilot tested. The questionnaire...... (66%) and relatives were the most dissatisfied with the lack of inclusion in decision making related to treatment and care (71%) and the length of time required to diagnose cancer (70%). Responses to the open-ended questions revealed that relatives faced challenges in gaining access to information...

    When individuals stop working due to cancer this represents a loss to society - the loss of productivity. The aim of this analysis was to estimate productivity losses associated with premature mortality from all adult cancers and from the 20 highest mortality adult cancers in Ireland in 2011, and project these losses until 2030. An incidence-based method was used to estimate the cost of cancer deaths between 2011 and 2030 using the Human Capital Approach. National data were used for cancer, population and economic inputs. Both paid work and unpaid household activities were included. Sensitivity analyses estimated the impact of assumptions around future cancer mortality rates, retirement ages, value of unpaid work, wage growth and discounting. The 233,000 projected deaths from all invasive cancers in Ireland between 2011 and 2030 will result in lost productivity valued at €73 billion; €13 billion in paid work and €60 billion in household activities. These losses represent approximately 1.4 % of Ireland's GDP annually. The most costly cancers are lung (€14.4 billion), colorectal and breast cancer (€8.3 billion each). However, when viewed as productivity losses per cancer death, testis (€364,000 per death), cervix (€155,000 per death) and brain cancer (€136,000 per death) are most costly because they affect working age individuals. An annual 1 % reduction in mortality reduces productivity losses due to all invasive cancers by €8.5 billion over 20 years. Society incurs substantial losses in productivity as a result of cancer-related mortality, particularly when household production is included. These estimates provide valuable evidence to inform resource allocation decisions in cancer prevention and control.

    BACKGROUND AND PURPOSE: Myotonic dystrophies (DM) are autosomal dominantly inherited neuromuscular disorders caused by unstable nucleotide repeat expansions. DM and cancer have been associated, but the pathogenesis behind the association remains unclear. It could relate to derived effects of the DM...... genotype in which case non-DM relatives of DM patients would not be expected to be at increased risk of cancer. To elucidate this, a population-based cohort study investigating risk of cancer in relatives of DM patients was conducted. METHODS: DM was identified u
