This study represents a comparison of the functional interrelation of fatigue and cognitive, cardiovascular and autonomic nervous systems in a group of Chronic Fatigue Syndrome (CFS) patients compared with those in healthy individuals at different stages of analysis: at baseline and after changes induced by whole-body cryotherapy (WBC) combined with a static-stretching (SS) program. The study included 32 patients (Fukuda criteria) and 18 healthy controls. Fatigue, cognitive, cardiovascular and autonomic function and arterial stiffness were measured before and after 10 sessions of WBC with SS. In the patients, a disturbance in homeostasis was observed. The network relationship based on differences before and after intervention showed comparatively higher stress and eccentricity in the CFS group: 50.9 ± 56.1 vs. 6.35 ± 8.72, p = 0.002, r = 0.28; and 4.8 ± 0.7 vs. 2.4 ± 1, p < 0.001, r = 0.46, respectively. Before and after intervention, in the CFS group increased fatigue was related to baroreceptor function, and baroreceptor function was in turn related to aortic stiffness, but no such relationships were observed in the control group. Differences in the network structure underlying the interrelation among the four measured criteria were observed in both groups, before the intervention and after ten sessions of whole cryotherapy with a static stretching exercise.

Background. The role of stress in the onset of chronic fatigue syndrome is unclear. Our objectives in this study were first, to determine the relation between the onset of chronic fatigue syndrome and stressful life events and difficulties. Secondly, we examined the role of a particular type of problem, dilemmas, in the onset of chronic fatigue syndrome.Method. We used a case–control design with 64 consecutive referrals from an Infectious Diseases/Liaison Psychiatry Fatigue clinic and 64 age- and sex-matched controls from a general practice population control group in Leeds. We had two main outcome measures; the odds ratios of the risk of developing chronic fatigue syndrome after experiencing a severe life event, severe difficulties or both in the year and 3 months preceding onset; and the proportion of subjects in each group who experienced a dilemma prior to onset.Results. Patients with chronic fatigue syndrome were more likely to experience severe events and difficulties in the 3 months (OR=9, 95% CI 3·2 to 25·1) and year (OR=4·3, 95% CI 1·8 to 10·2) prior to onset of their illness than population controls. In the 3 months prior to onset 19 of the 64 patients (30%) experienced a dilemma compared to none of the controls.Conclusions. Chronic fatigue syndrome is associated with stressful events and difficulties prior to onset. Those events and difficulties characterized as being dilemmas seem to be particularly important.

Purpose. The aim of the present study was to elucidate the metabolic mechanisms associated with chronic fatigue syndrome (CFS) via an analysis of urine metabolites prior to and following exercise in a rat model. Methods. A rat model of CFS was established using restraint-stress, forced exercise, and crowded and noisy environments over a period of 4 weeks. Behavioral experiments were conducted in order to evaluate the model. Urine metabolites were analyzed via gas chromatography-mass spectrometry (GC-MS) in combination with multivariate statistical analysis before and after exercise. Results. A total of 20 metabolites were detected in CFS rats before and after exercise. Three metabolic pathways (TCA cycle; alanine, aspartate, and glutamate metabolism; steroid hormone biosynthesis) were significantly impacted before and after exercise, while sphingolipid metabolism alone exhibited significant alterations after exercise only. Conclusion. In addition to metabolic disturbances involving some energy substances, alterations in steroid hormone biosynthesis and sphingolipid metabolism were detected in CFS rats. Sphingosine and 21-hydroxypregnenolone may be key biomarkers of CFS, potentially offering evidence in support of immune dysfunction and hypothalamic-pituitary-adrenal (HPA) axis hypoactivity in patients with CFS.

In this review, we consider the paper by Adamson et al., published in the October 2020 issue of the Journal of the Royal Society of Medicine. The authors interpret their data as revealing significant improvements following cognitive behavioural therapy in a large sample of patients with chronic fatigue syndrome and chronic fatigue. Overall, the research is hampered by several fundamental methodological limitations that are not acknowledged sufficiently, or at all, by the authors. These include: (a) sampling ambiguity; (b) weak measurement; (c) survivor bias; (d) missing data; and (e) lack of a control group. In particular, the study is critically hampered by sample attrition, rendering the presentation of statements in the Abstract misleading with regard to points of fact, and, in our view, urgently requiring a formal published correction. In light of the fact that the paper was approved by multiple peer-reviewers and editors, we reflect on what its publication can teach us about the nature of contemporary scientific publication practices.

Severe, persisting fatigue is a prominent symptom of Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS), but individuals with this illness frequently report the occurrence of unique fatigue states that might be different from conventional symptoms of fatigue. The present study attempted to assess a comprehensive set of fatigue symptoms that have been commonly reported among patients with ME/CFS. A 22-item fatigue questionnaire was developed and administered to 130 persons diagnosed with ME/CFS and 251 controls. Adequate scale reliability was found. Factor analyses revealed a five-factor structure for participants with ME/CFS but only a one factor solution for the control group. The new scale was also contrasted with other more traditional scales developed to measure fatigue. Findings suggest that individuals with ME/CFS experience different types of fatigue than what are reported in the general populations.

Objective. This review aimed at systematically evaluating the efficacy and safety of moxibustion for chronic fatigue syndrome (CFS). Methods. Relevant trials were searched in seven digital databases up to January 2021. After literature screening, data extraction, and literature quality evaluation, the included studies were meta-analyzed using RevMan 5.4 software. The evidence level was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). Results. Fifteen studies involving 1030 CFS participants were included. Meta-analyses showed a favorable effect of moxibustion on the total effective rate compared with acupuncture (OR = 4.58, 95%CI = [2.85, 7.35], P < 0.00001 ) and drugs (OR = 6.36, 95%CI = [3.48, 11.59], P < 0.00001 ). Moxibustion also appeared to significantly reduce fatigue severity measured by fatigue scale-14 (FS-14) (WMD = −2.20, 95% CI = [−3.16, −1.24], P < 0.00001 ) and fatigue assessment instrument (FAI) (WMD = −16.36, 95% CI = [−26.58, −6.14], P = 0.002 ) compared with the control group. In addition, among the 15 included studies, only two studies reported adverse events related to moxibustion, and the symptoms were relatively mild. The quality of evidence based on the 15 included trials was assessed as moderate to very low. Conclusions. Based on limited evidence, moxibustion might be an effective and safe complementary therapy for CFS, which can be recommended to manage CFS. Because of the limited level of evidence in this review, further high-quality trials are still needed to confirm these findings.

Background: Previous research has suggested that enteroviruses may be implicated in the development and persistence of Chronic Fatigue Syndrome (CFS). One method of investigating this topic has been to use a polio vaccination challenge, and a previous study showed that CFS patients had more shedding than healthy controls. There was no effect of the vaccination on the clinical condition or wellbeing of the CFS patients. Methods: In the previous study, the control group were more likely to have had a recent booster vaccination. This was controlled in the present study, where 18 CFS patients were randomly assigned to vaccination or placebo conditions. Nine healthy volunteers were also given the polio vaccination. Results: The results confirmed that vaccination had no negative effects on the CFS group. Although there was more virus shedding in the CFS polio group than in the control polio group, this difference was not significant. Conclusion: This study confirms that polio vaccination is not contraindicated in CFS patients but could not confirm that they are more susceptible to enterovirus infection.

Abstract Background: Nursing is considered a stressful profession, so nurses are at higher risk of physical and mental illness. Mindfulness is an important concept for nursing with practical implications for nurse well-being, development, and quality nursing care sustainability.Objectives: This study identified mindfulness sessions' effect on nurses' chronic fatigue syndrome(CFS) and job satisfaction )JS.(Methods: A randomized clinical trial design was conducted on 80 nurses to intervention and control groups. The intervention in the intervention group was eight mindfulness sessions training, and the control group had no intervention. Nurses' CFS and JS were assessed using the Minnesota Satisfaction Questionnaire and The Multidimensional Fatigue Inventory.Results: After implementing a mindfulness-based stress reduction program, the intervention group nurses reported lower CFS and higher JS than the control group(p<0.005). Conclusion: The findings of this study indicate the effectiveness of mindfulness programs on improving nurses' chronic fatigue and JS. Since CFS and job dissatisfaction are two disturbing elements for nurses' optimal performance in professional and personal life, this study can recommend the implementation of mindfulness exercises as a routine, operational and uncomplicated program in nurses.

Purpose: Since physical exertion is known to exacerbate the symptoms of chronic fatigue syndrome (CFS) and metabolic changes and including oxidative stress can modulate heat shock protein (HSP) expression responses, we sought to determine whether HSP expression is altered in CFS patients before and after exercise. Heat shock proteins (HSPs) in peripheral blood mononuclear cells (PBMC) were examined from 6 chronic fatigue syndrome (CFS) patients and 7 controls before and after a standardized treadmill exercise. Basal hsp27 was significantly higher among CFS patients compared to controls, and decreased immediately post-exercise, remaining below basal levels even at 7 days. A similar pattern was observed for HSP60, which gradually decreased in CFS patients but increased in controls post-exercise. These findings suggest an abnormal adaptive response to oxidative stress in CFS, and raise the possibility that HSP profiling may provide a more objective biologic marker for this illness. Methods: HSP27, HSP60, HSP70 and HSP90 expression from 6 CFS patients and 7 age- and sex-matched controls were examined by western blot analysis of peripheral blood mononuclear cells immediately before, after, and at 1 day and 7 days following a standardized treadmill exercise. Results: Basal HSP27 was higher among CFS patients than in controls (0.54 ± 0.13 vs. 0.19 ± 0.06, mean ± SEM; P < 0.01). In addition, these levels in CFS patients decreased immediately post-exercise (0.25 ± 0.09; P < 0.05) and remained below basal levels at day 1 post-exercises (0.18 ± 0.05; P < 0.05). P < 0.05). This declining expression of HSP27 during the post-exercise period among CFS patients was confirmed by one-way ANOVA analysis with repeated measures (P < 0.05). In contrast, HSP27 levels remained relatively constant following exercise among control subjects. Similar patterns of declining HSP levels in CFS patients were also observed for HSP60 (0.94 ± 0.40 vs. 1.32 ± 0.46; P < 0.05), and for HSP90 (0.34 ± 0.09 vs. 0.49 ± 0.10; P < 0.05) at day 7 post-exercise compared with basal levels, respectively. In contrast, HSP60 levels in control subjects increased at day 1 (1.09 ± 0.27) and day 7 (1.24 ± 0.50) post-exercise compared to corresponding levels immediately post-exercise (0.55 ± 0.06) (P < 0.05, respectively). Conclusion: These preliminary findings suggest an abnormal or defective adaptive response to oxidative stress in CFS, and raise the possibility that HSP profiling may provide a more objective biologic marker for this illness.
