Abstract
OBJECTIVE Fatigue is a common, debilitating syndrome after stroke. Peripheral inflammation plays a role in the pathogenesis of fatigue of different origin, but its contribution to post-stroke fatigue (PSF) remains unclear. We aimed to determine if there is any association between ex vivo synthesized and circulating cytokines, and risk of PSF. METHODS We included 174 patients with ischemic stroke. We stimulated in vitro blood taken on day 3 after stroke with endotoxin. We measured ex vivo released (TNFα, IP-10, IL-1β, IL-6, IL-8, IL-10, IL-12p70) and plasma (TNFα, IL-6, sIL-6R, IL-1Ra) cytokines. We assessed fatigue at month 3 using Fatigue Severity Scale (FSS). We used logistic regression to assess the relationship between cytokines and fatigue scores. RESULTS Compared with patients with lower fatigue at month 3 (FSS < 36), patients with higher fatigue (FSS ≥ 36) had lower endotoxin-stimulated TNFα release after 24 h (median: 429 vs 581 pg/mL, P = 0.05). Plasma TNFα tended to be higher in patients who developed fatigue (median: 0.8 vs 0.6 pg/mL, P = 0.06). Other cytokines did not differ between groups. After adjusting for pre-stroke fatigue and depressive symptoms, TNFα release <559.7 pg/mL after 24 h was associated with an increased risk of PSF (OR: 2.61, 95%CI: 1.22-5.57, P = 0.01). Plasma TNFα >0.76 pg/mL was associated with higher risk of PSF in univariable (OR: 2.41, 95%CI: 1.13-5.15, P = 0.02), but not multivariable analysis (OR: 2.41, 95%CI: 0.96-6.00, P = 0.06). CONCLUSION Reduced ex vivo TNFα synthesis upon whole blood stimulation with endotoxin in the acute phase of stroke predicted PSF.

Abstract
Major depressive disorder (MDD) is an important contributor to the total disease burden because of its high comorbidity with chronic illnesses. Many people with high levels of depressive symptoms exhibit elevated systemic inflammation, but inflammation is not a necessary determinant of depression onset. Among those who recently experienced the death of a spouse, we investigated whether (a) inflammation assessed early in bereavement predicted future depressive symptoms and whether (b) inflammation predicted change in depressive symptoms from baseline to follow-up. Ninety-nine spousally bereaved individuals (M=68.61, SD=10.70) from a larger study were evaluated at baseline (3 months post-death) and follow-up (6 months post-death). Subjects received a venous blood draw and completed the Center for Epidemiologic Studies Depression Scale (CES-D). Stimulated T-cell derived cytokines (IL-6, TNF-α, and IFN-γ) were assessed individually and as a pro-inflammatory composite index. After controlling for confounding factors (i.e., age, sex, body mass index, race, ethnicity, anti-inflammatory medication, days since spousal death, smoking status, comorbidities), individuals with higher levels of IL-6, TNF-α, and IFN-γ at baseline exhibited more depressive symptoms (composite index, p = .05) and an increased probability of experiencing clinical levels of depression (CES-D score ≥16) (composite index, p = .04). Inflammatory levels were not predictive of change in depressive symptoms or in clinical depression status from baseline to follow-up. Among individuals who did not experience clinical levels of depression at baseline, baseline inflammatory levels predicted clinical levels of depression 3 months later (p = .03). This study provides support for an inflammatory mechanism underlying depression following bereavement. It suggests that one's inflammatory profile following a significant social stressor in older adulthood can be prognostic of depression risk months later. These findings add to our understanding of the physiological and mental health risks experienced by the bereaved population and provide insight into identifying vulnerable widow(er)s at risk for maladaptive grief coping.

Abstract
Health-related quality of life (HRQoL) describes an individual's perception of the impact of health, disease, and treatment on their quality of life (QoL). It is a reflection of how the manifestation of an illness and its treatment is personally experienced. Assessing HRQoL is particularly important in sarcoidosis because the attributable disease mortality is relatively low, and one of the major reasons for initiating treatment is to improve quality of life. HRQoL has been assessed in sarcoidosis using various generic and sarcoid-specific patient-reported outcome measures (PROMs). It is important that both the direct and indirect effects of the disease, as well as potential toxicities of therapy, are captured in the various PROMs used to assess HRQoL in sarcoidosis. This article provides a general overview of HRQoL in patients with sarcoidosis. It describes the various PROMs used to assess HRQoL in sarcoidosis and addresses the various factors that influence HRQoL in sarcoidosis. Specific attention is paid to fatigue, small fiber neuropathy, corticosteroid therapy, and other disease-specific factors that affect HRQoL in sarcoidosis. It also provides an insight into interventions that have been associated with improved HRQoL in sarcoidosis and offers suggestions for future research in this important area.

Abstract
Spousal bereavement is associated with an elevated risk of morbidity and mortality. Several well-regarded multidisciplinary research teams have sought to understand the biopsychosocial processes underlying why widow(er)s are at elevated physical health risk. In this paper, we review research from multiple investigatory teams, including our own, showing that, on average, widow(er)s exhibit maladaptive patterns of autonomic, neuroendocrine, and immune activity compared to matched comparisons. Widow(er)s also exhibit poorer health behaviors than they did before their spouse's death. There is considerable variation in post-loss psychological adjustment trajectories among widow(er)s, which likely corresponds to physical health risk trajectories. Yet, there is little biobehavioral research on patterns of change in physical health risk after the death of a spouse. We summarize recently published work demonstrating the utility of attachment theory to characterize and predict individual differences in physical health biomarkers; we highlight the need for a biopsychosocial approach to understand and characterize post-loss trajectory patterns. We conclude by discussing the possibility that this line of inquiry could help researchers, and ultimately providers, identify adjustment trajectories earlier and thus deliver appropriate interventions when they are most needed.

Abstract
Fatigue is one of the most burdensome symptoms in interstitial lung disease (ILD) and can have a major impact on quality of life, social interactions, and work capacity. The cause of fatigue is complex; it is caused or aggravated by a combination of different predisposing, precipitating, and perpetuating factors. There is no uniform definition of fatigue, but it is often divided in physical and mental components. Several validated questionnaires can be used for structural assessment of fatigue in daily care. Although the high burden of fatigue in ILD is recognized increasingly, studies that have investigated pharmacologic and nonpharmacologic treatment options are scarce. Because fatigue in ILD is often a multifactorial problem, therapeutic interventions ideally should be aimed at different domains. One of the first steps is to optimize treatment of the underlying disease. Subsequently, treatable causes of fatigue should be identified and treated. Recently, an increasing number of studies showed that supportive measures have the potential to improve fatigue. However, evidence-based treatment guidelines are lacking, and more research is highly needed in this field. In clinical practice, a comprehensive, multidisciplinary, and individually tailored approach seems best fit to optimize treatment of fatigue in patients with ILD.

Abstract
Stressful life events such as losing a spouse can enhance inflammation. Responses to loss may depend, in part, on individual differences in attachment anxiety and avoidance. An individual's attachment orientation (i.e., an individual's levels of attachment anxiety and avoidance) reflects how an individual relates to others-- specifically, whether they feel their trusted others will reliably be there for them, and whether they feel comfortable opening up to and depending on their relationship partners. This study investigated the association between attachment orientations and poor loss adjustment in recently bereaved individuals (N = 100). Poor loss adjustment was operationalized as greater levels of inflammation and grief symptoms, as well as poorer self-reported mental and physical health. Attachment anxiety was associated with increased stimulated monocyte IL-6 and CCL4 production, but not TNFα. Likewise, attachment anxiety was associated with greater grief symptoms as well as poorer mental and physical health. In contrast, attachment avoidance was not associated with inflammation; it was, however, associated with less grief symptoms as well as better self-reported mental and physical health. Our findings provide evidence that attachment orientations may be associated with loss adjustment and adverse health outcomes following the recent loss of a spouse.

Abstract
Sarcoidosis is an inflammatory disorder of unknown cause that is characterized by granuloma formation in affected organs, most often in the lungs. Patients frequently suffer from cough, shortness of breath, chest pain and pronounced fatigue and are at risk of developing lung fibrosis or irreversible damage to other organs. The disease develops in genetically predisposed individuals with exposure to an as-yet unknown antigen. Genetic factors affect not only the risk of developing sarcoidosis but also the disease course, which is highly variable and difficult to predict. The typical T cell accumulation, local T cell immune response and granuloma formation in the lungs indicate that the inflammatory response in sarcoidosis is induced by specific antigens, possibly including self-antigens, which is consistent with an autoimmune involvement. Diagnosis can be challenging for clinicians because of the potential for almost any organ to be affected. As the aetiology of sarcoidosis is unknown, no specific treatment and no pathognomic markers exist. Thus, improved biomarkers to determine disease activity and to identify patients at risk of developing fibrosis are needed. Corticosteroids still constitute the first-line treatment, but new treatment strategies, including those targeting quality-of-life issues, are being evaluated and should yield appropriate, personalized and more effective treatments.

Abstract
Grief is conceptualized by strong negative emotions, which include longing, sadness, and preoccupations with thoughts, recollections, and images of the spouse. In the initial months after the loss of a spouse, those who are widowed are at risk for cardiovascular problems and premature mortality. In the general population, depression is characterized by chronic low-grade inflammation, a key predictor of cardiovascular problems, morbidity, and mortality. Although depression and grief share similarities, they are distinct constructs. We aimed to identify if grief was related to inflammation among those who had a spouse recently die. We also sought to determine if those who are widowed and already experience elevated levels of depressive symptoms compared with the general population had higher levels of inflammation compared with those who are widowed who report fewer depressive symptoms. Ninety-nine recently bereaved individuals (M = 84.74 days since passing, SD = 18.17) completed a blood draw and psychological assessments. Proinflammatory T cell-derived cytokines were assessed, which included interferon gamma (IFN-γ), interleukin (IL)-6, tumor necrosis factor alpha (TNF-α), IL17-A, and IL-2. Bereaved individuals with a higher grief severity (using an established cut-score) had higher levels of the proinflammatory cytokines IFN-γ, IL-6, and TNF-α than those with less grief severity. Those who experienced higher levels of depression exhibited elevated levels of proinflammatory cytokines compared with those who had lower levels of depression (using a continuous measure of depressive symptoms, as well as an established cut score). This is the first study to demonstrate that inflammatory markers can distinguish those who are widowed based on grief severity such that those who are higher on grief severity have higher levels of inflammation compared with those who are lower on grief severity. These findings also add to the broader literature on depression and inflammation by showing that even in a population with high levels of depressive symptoms, there is a positive relationship between depression and inflammation.

Abstract
BACKGROUND Fibromyalgia (FM) is a syndrome characterized by widespread chronic pain associated to other symptoms, such as: fatigue, anxiety, depression and sleep disorders. Health education programs (HEP) have emerged as good non-pharmacological strategies to treat it. However, it is still not clear if the benefits are only subjective, or it has also objective impacts on immune and or neuroendocrine systems. METHODS Fifty-eight fibromyalgia women were randomly allocated in experimental group (n = 27) or control group (n = 31). The experimental group was submitted to HEP treatment for 11 weeks, while control group did not receive intervention at the same period. All data were collected at zero and 11th week by a blinded researcher. The statistical analysis were made in GraphPad Prism software (version 5.0) with significant level adjusted for α = 0.05. RESULTS Forty-four patients concluded the full study, 21 in the experimental group and 23 in the control group. Intragroup and intergroup analysis revealed that treatment induced significant increases of IL-4 plasma levels, anti-inflammatory cytokine/inflammatory cytokine ratio (AC/IC ratio), salivary cortisol levels, in addition to significant decreases on FIQ scores. Intergroup variation analyses revealed also significant increases of IL-10 plasma levels. CONCLUSION The results presented suggest that this kind of HEP could induce subjective and objective changes (immune and neuroendocrine), that could explain, at least in part the improvement of fibromyalgia patient's health status.

Abstract
The loss of a spouse is a highly stressful event that puts people at excess risk of mortality. Excess mortality among those who are widowed is highest in the first six months after the death of a spouse and decreases over time. Heart disease accounts for the largest proportion of these deaths. The psychological stress associated with stressful life events can enhance inflammation and lower heart rate variability (HRV). Both lower HRV and higher inflammation are risk factors for cardiovascular morbidity and mortality. Thirty-two recently bereaved individuals (Mean = 89.68 days since death, SD = 17.09) and 33 age-matched comparisons completed a blood draw, EKG, and self-report questionnaires. In both adjusted and unadjusted models, spousal bereavement was associated with enhanced pro-inflammatory cytokine production by in vitro lipolysaccharide-stimulated peripheral blood leukocytes. Moreover, spousal bereavement was associated with lower HRV in comparison to the comparison group. This study is the first to demonstrate that bereavement is associated with a more pronounced ex vivo cytokine production and lower HRV in a population that exclusively consisted of widows and widowers. These findings add to the growing literature revealing the mechanisms that underlie bereavement-related cardiovascular problems. Future longitudinal studies are needed to determine the temporal relation between these risks. Understanding the biological mechanisms that underlie this stressful life event could allow researchers to create therapeutic targets for interventions to reduce or prevent the toll of a "broken heart."

Abstract
Fatigue is commonly reported in a variety of illnesses, and it has major impact on quality of life. Previously, it was thought that fatigue originates in the skeletal muscles, leading to cessation of activity. However, more recently, it has become clear that the brain is the central regulator of fatigue perception. It has been suggested that pro-inflammatory cytokines, especially interleukin-1 alpha (IL-1α) and interleukin-1 beta (IL-1β), play a prominent role in the development of central fatigue, and several studies have been performed to elucidate the connection between inflammation and these central processes.In this narrative review, mechanisms of action of IL-1 are described, with special attention to its effect on the central nervous system. In addition, we present a summary of studies that (i) investigated the relationship between circulating IL-1α and IL-1β and fatigue severity and/or (ii) evaluated the effect of inhibiting IL-1 on fatigue. We aim to improve the understanding of fatigue in both inflammatory and non-inflammatory illnesses, which could help develop strategies to treat fatigue more effectively.Reviewing the studies that have been performed, it appears that there is a limited value of measuring circulating IL-1. However, inhibiting IL-1 has a positive effect on severe fatigue in most studies that have been conducted.

Abstract
OBJECTIVE Combat stress exposed soldiers may respond to post-deployment stressful life events (SLE) with increases in symptoms of posttraumatic stress disorder (PTSD), consistent with a model of stress sensitization. Several lines of research point to sensitization as a model to describe the relations between exposure to traumatic events, subsequent SLE, and symptoms of PTSD. Based on previous findings we hypothesized that immune activation, measured as a high in vitro capacity of leukocytes to produce cytokines upon stimulation, underlies stress sensitization. METHODS We assessed mitogen-induced cytokine production at 1 month, SLE at 1 year, and PTSD symptoms from 1 month up to 2 years post-deployment in soldiers returned from deployment to Afghanistan (N=693). Exploratory structural equation modeling as well as latent growth models were applied. RESULTS The data demonstrated significant three-way interaction effects of combat stress exposure, cytokine production, and post-deployment SLE on linear change in PTSD symptoms over the first 2 years following return from deployment. In soldiers reporting high combat stress exposure, both high mitogen-stimulated T-cell cytokine production and high innate cytokine production were associated with increases in PTSD symptoms in response to post-deployment SLE. In low combat stress exposed soldiers as well as those with low cytokine production, post-deployment SLE were not associated with increases in PTSD symptoms. CONCLUSION High stimulated T-cell and innate cytokine production may contribute to stress sensitization in recently deployed, high combat stress exposed soldiers. These findings suggest that detecting and eventually normalizing immune activation may potentially complement future strategies to prevent progression of PTSD symptoms following return from deployment.

Quantifying fatigue in (long-term) colorectal cancer survivors: a study from the population-based patient reported outcomes following initial treatment and long term evaluation of survivorship registry. Eur J Cancer 2013; 49:1957-66.

Abstract
BACKGROUND Few studies specifically focus on fatigue of (long-term) colorectal cancer (CRC) survivors or compare fatigue levels with a normative population. Association between surviving multiple primary cancers and fatigue is also explored. METHODS Survivors diagnosed from 1998 to 2009 were identified from the Eindhoven Cancer Registry. In total, 3739 (79%) respondents and an age- and gender-matched normative population (n=338) completed questionnaires on fatigue and psychological distress. RESULTS More survivors reported feeling fatigued than the normative population (39% versus 22%, p<0.0001). Short-term survivors (<5 years post-diagnosis) had the highest mean fatigue scores compared with long-term survivors (≥5 years post-diagnosis) or the normative population (21±7 versus 20±7 versus 18±5, p<0.0001, respectively). Having primary cancers prior to CRC was associated with more fatigue. Surgery+chemoradiation was independently associated with fatigue (odds ratio (OR): 1.63, 95% confidence interval (CI): 1.17-2.29, p=0.004) as were anxiety (OR: 1.16, 95% CI: 1.12-1.19, p<0.0001) and depressive symptoms (OR: 1.38, 95% CI: 1.33-1.43, p<0.0001). CONCLUSIONS Fatigue is a significant problem, especially for short-term CRC survivors. The association between chemoradiation and fatigue suggests that patients could benefit from better information on treatment side-effects. When treating fatigue, clinical care should also focus on survivors' psychological needs, especially survivors of multiple primary cancers.

Abstract
Cancer therapy makes patients sick. The therapies that are available to clinicians allow them to successfully control nausea, emesis and pain. However, this is not the case for a number of other symptoms that include fatigue, distractibility, poor memory, and diminished interest in previously pleasurable activities. These symptoms cluster during the course of cancer therapy and impair patient quality of life, limit therapy options and do not always resolve at the cessation of treatment. It is possible to describe the intensity and temporal features of symptoms and assess their relationship with the inflammatory response that is associated with cancer and cancer therapy. At the preclinical level, sophisticated animal models still need to be deployed to study the causal role of inflammation in specific components of cancer-related symptoms. Various approaches can be optimally combined in a translational symptom research pathway to provide a framework for assessing in a systematic manner the neurobehavioral toxicity of existing and newly developed cancer therapies. Ultimately, this knowledge will allow derivation of mechanism-based interventions to prevent or alleviate cancer-related symptoms.

Abstract
OBJECTIVES Chronic fatigue following inflammatory diseases has been well documented. However, little is known about possible risk factors of chronic post-inflammatory fatigue. The aim of this study was to investigate whether chronic post-inflammatory fatigue after clinical remission of the disease sarcoidosis is associated with specific dimensions of personality, psychological symptoms and baseline levels of stress hormones. METHODS Thirty-seven non-fatigued and 33 fatigued patients in clinical remission of sarcoidosis were evaluated with the Temperament and Character Inventory-short form (TCI); the Symptom CheckList-90 (SCL), and the Checklist Individual Strength (CIS). Baseline levels of ACTH and cortisol were measured in plasma. Principal component analysis with orthogonal rotation (varimax) was conducted on all personality, psychological and stress hormone data in order to obtain a smaller set of components. Logistic regression was performed to associate these components with chronic post-inflammatory fatigue. RESULTS Principal component analyses identified 5 components, of which two components were significantly associated with chronic post-inflammatory fatigue. The first component comprised the personality trait Harm Avoidance and all SCL-subscales except Sleep. The second component consisted of baseline levels ACTH and cortisol, and showed an inverse association with chronic post-inflammatory fatigue. The 3 other components, consisting of respectively SCL-Sleep, TCI-Novelty Seeking-Reward Dependence-Self Transcendence, and TCI-Persistence, were not significantly associated with chronic fatigue. CONCLUSION Chronic post-inflammatory fatigue after clinical remission of sarcoidosis is associated with a triad of risk factors: a specific personality profile with profound neurotic characteristics in combination with high levels of psychological distress, and decreased baseline ACTH/cortisol levels.

Cytokine production by leukocytes of military personnel with depressive symptoms after deployment to a combat-zone: a prospective, longitudinal study. PLoS One 2011; 6:e29142.

Abstract
Major depressive disorder (MDD) is frequently diagnosed in military personnel returning from deployment. Literature suggests that MDD is associated with a pro-inflammatory state. To the best of our knowledge, no prospective, longitudinal studies on the association between development of depressive symptomatology and cytokine production by peripheral blood leukocytes have been published. The aim of this study was to investigate whether the presence of depressive symptomatology six months after military deployment is associated with the capacity to produce cytokines, as assessed before and after deployment. 1023 military personnel were included before deployment. Depressive symptoms and LPS- and T-cell mitogen-induced production of 16 cytokines and chemokines in whole blood cultures were measured before (T0), 1 (T1), and 6 (T2) months after return from deployment. Exploratory structural equation modeling (ESEM) was used for data reduction into cytokine patterns. Multiple group latent growth modeling was used to investigate differences in the longitudinal course of cytokine production between individuals with (n = 68) and without (n = 665) depressive symptoms at T2. Individuals with depressive symptoms after deployment showed higher T-cell cytokine production before deployment. Moreover, pre-deployment T-cell cytokine production significantly predicted the presence of depressive symptomatology 6 months after return. There was an increase in T-cell cytokine production over time, but this increase was significantly smaller in individuals developing depressive symptoms. T-cell chemokine and LPS-induced innate cytokine production decreased over time and were not associated with depressive symptoms. These results indicate that increased T-cell mitogen-induced cytokine production before deployment may be a vulnerability factor for development of depressive symptomatology in response to deployment to a combat-zone. In addition, deployment to a combat-zone affects the capacity of T-cells and monocytes to produce cytokines and chemokines until at least 6 months after return.

Abstract
OBJECTIVE Fatigue is frequently reported in sarcoidosis and appears to differ between patients. Three types of fatigue (Early Morning Fatigue, Intermittent Fatigue, and Afternoon Fatigue) are described in the literature for sarcoidosis, but have not been validated. Therefore, the aim of this study was to examine whether these types of fatigue can be identified in sarcoidosis. METHODS Outpatients (n=434) from Maastricht University Medical Centre participated in this study. Data were obtained from medical records. Patients also completed questionnaires regarding depressive symptoms, fatigue, quality of life, restless legs, dyspnea, depressive symptoms, anxiety, sleeping problems, symptoms indicative for small fiber neuropathy, and employment. RESULTS Latent Cluster Analysis revealed three clusters: 1) Mild Fatigue: patients with mild or no complaints of fatigue, 2) Intermittent Fatigue: patients with complaints of fatigue that varied during the day, and 3) All Day Fatigue: patients who felt tired the whole day. The three patient clusters differed regarding clinical, psychological, and demographical characteristics, with All Day Fatigue patients reporting the most complaints. CONCLUSION Intermittent fatigue was validated and two other types were found. Careful consideration to categorize patients with sarcoidosis in the three types of fatigue will help healthcare providers to understand the challenges these patients encounter. The usefulness of psychological counseling should be evaluated in future research in order to improve the wellbeing of the patients, especially for those with All Day Fatigue.
