ABSTRACT

BACKGROUND: Limited published data suggests that absence of uplifts (minor pleasant events) is associated with clinical worsening in patients with chronic fatigue syndrome (CFS). The current study aimed to assess the relation of illness worsening to the trajectories of social and non-social uplifts and hassles in a six-month prospective study in CFS. METHODS: Participants were primarily in their 40s, female, white, and ill for over a decade. All participants (N = 128) met criteria for CFS. The interview-based global impression of change rating was used to classify individual outcomes as improved, unchanged, or worsened at six- month follow-up. Uplifts and hassles, both social and non-social, were assessed with the Combined Hassles and Uplifts Scale (CHUS). The CHUS was administered weekly in online diaries over six months. Linear mixed effect models were utilized to examine linear trends for hassles and uplifts. RESULTS: No significant differences were found between the three global outcome groups for age, sex, or illness duration; however, work status was significantly lower for the non-improved groups (p < 0.001). Non-social hassles intensity showed an increasing slope for the worsened group (p = 0.03) and a decreasing slope (p = 0.05) for the improved group. For the worsened group, a downward trend was found for frequency of non-social (p = 0.01) uplifts. CONCLUSION: Individuals with worsening as compared to improving illness in CFS show significantly different six-month trajectories for weekly hassles and a deficit in uplifts. This may have clinical implications for behavioral intervention. Trial registration ClinicalTrials.gov ID: NCT02948556.

ABSTRACT

To assess biobehavioral sex differences in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) utilizing a low burden exercise protocol, 22 females and 15 males with ME/CFS and 14 healthy controls underwent two six-min walk tests. Fifteen daily assessments were scheduled for fatigue and function ratings and heart monitoring. Six-min walk tests were conducted on days 8 and 9. The ME/CFS group showed high self-report fatigue and impaired physical function, whereas healthy controls did not show fatigue or function abnormalities. In patients, no significant post-exercise changes were found for heart rate variability (HRV); however, heart rate decreased in ME/CFS males from Day 14 to Day 15 (p = 0.046). Female patients showed increased fatigue (p = 0.006) after the initial walk test, but a downward slope (p = 0.008) in fatigue following the second walk test. Male patients showed a decrease in self-report work limitation in the days after exercise (p = 0.046). The healthy control group evidenced a decrease in HRV after the walk tests from Day 9-14 (p = 0.038). This pilot study did not confirm hypotheses that females as compared to males would show slower exercise recovery on autonomic or self-report (e.g. fatigue) measures. A more exertion-sensitive test may be required to document prolonged post-exertional abnormalities in ME/CFS.Trial registration: NCT NCT03331419.

ABSTRACT

OBJECTIVE: To test a model of nonimprovement in chronic fatigue syndrome (CFS) using self-report activity patterns (e.g., "push-crash"), uplifts and hassles, and a biological measure of cardiac autonomic function. Activity pattern impacts on symptoms and objective measures of autonomic and physical activity were also examined. METHODS: This prospective study in CFS collected all data remotely, including 6 months of weekly web diaries that recorded symptom ratings, activity patterns, and hassles and uplifts. In addition, 6 months of weekly heart monitoring and 3 months of daily waking actigraphy data were collected. Improvement or nonimprovement status was assessed using semistructured interviews at the 6-month follow-up. RESULTS: A total of 148 individuals (87.2% female) were enrolled, and 12.2% were lost to follow-up. Participants reporting nonimprovement ( n = 92), as compared with improvement ( n = 38), showed greater autonomic dysfunction (lower heart rate variability, group difference = 5.93 [SE = 2.73] milliseconds; p = .032) and lower mean intensity of behavioral uplifts (group difference = 0.14 [SE = 0.16]; p = .043), but no significant differences in any activity pattern, including push-crash, limiting activity, and healthy pacing. CONCLUSIONS: This study provided evidence for linking patient-reported nonimprovement to a biological variable indexing autonomic dysfunction and a behavioral measure indicating a deficit in psychological uplifts. These findings suggest a possible marker of illness trajectory that could potentially advance the biomedical underpinnings of CFS.Trial Registration:ClinicalTrials.gov ID: NCT02948556.

ABSTRACT

BACKGROUND: Chronic fatigue syndrome is a complex chronic condition with large negative impact on patients' function and quality of life. Efficacy and cost-effectiveness of cognitive behavioral intervention remain inconclusive. OBJECTIVE: To evaluate the cost-utility of a home-based fatigue self-management (FSM) intervention as compared to usual care among primary care patients with severe chronic fatigue syndrome (CFS). METHODS: An economic evaluation alongside of a randomized controlled study design was used. Cost and utility data were collected from 137 patients with severe CFS at baseline and 1-year follow-up. The FSM group (n=89) received self-delivered cognitive behavioral self-management intervention and the usual care group (n=48) received regular medical care. Cost was measured by total costs (direct, indirect, and intervention costs) during the follow-up period. Quality-adjusted life years (QALY), as the utility measure, were derived from the Medical Outcomes Survey Short Form-36. A societal perspective was adopted. Bootstrapped incremental cost-utility ratios (ICURs) and net monetary benefit were calculated as measures of cost-effectiveness. RESULTS: Baseline individual characteristics were similar between the two groups. The intervention was well-received by the participants with only minimum attrition. At the end of one year post-intervention, FSM dominated usual care in terms of ICUR in both the intention-to-treat analysis and the complete-cases-only analysis. Net monetary benefit analysis showed that FSM has higher probability of achieving positive net monetary across the entire range of possible societal willingness-to-pay for fatigue symptom management. CONCLUSIONS: In primary care patients with severe CFS, the low-cost FSM appears to be a cost-effective treatment.

ABSTRACT

INTRODUCTION: The main objective was to evaluate the efficacy of an 8-session, group-based comprehensive smoking cessation and trauma management (CSC-T) treatment among daily smokers (≥5 cigarettes/day) exposed to the World Trade Center (WTC) disaster with elevated WTC-related post-traumatic stress disorder (PTSD) symptoms. METHODS: Participants (N = 90) were randomly assigned to CSC-T (N = 44; 63.6% white; 27.3% female; mean age = 51.32 ± 7.87) or comprehensive smoking cessation (CSC) alone (N = 46; 71.7% white; 28.3% female; mean age = 48.74 ± 10.66), which was comparable in length and time. Assessments included a diagnostic clinical interview and self-report measures of PTSD and respiratory symptoms, and smoking behavior, and biologically confirmed smoking abstinence. Evaluations occurred at a baseline visit, each treatment session, and at 1-, 2-, 4-, 12-, and 26-weeks post-treatment. RESULTS: The two treatments did not differ in regard to PTSD symptom improvement. After quit day (week 6), the two groups had similar 7-day (~15%) and 6-month (~20%) abstinence rates as well as average number of cigarettes smoked, and PTSD and respiratory symptoms. CONCLUSIONS: It is possible that the Cognitive Behavioral Therapy skills specific to quitting smoking, group-based support, and degree of therapist contact, that were available in both treatments may have played a role in equalizing the abstinence rates between the two conditions. Although the current study found no evidence that the CSC-T was superior to the CSC alone treatment, the abstinence rates observed were high relative to previous trials of smokers with diagnosed PTSD. Further development of smoking cessation programs tailored to the needs of smokers with PTSD symptoms continues to be needed. IMPLICATIONS: This study suggests that a CSC program aids in smoking abstinence for smokers with PTSD symptoms and that incorporating trauma management skills, may not add additional benefits for abstinence and PTSD and respiratory symptom relief. Further work is needed to improve smoking cessation efforts for smokers with PTSD symptoms.

ABSTRACT

The purpose of this mixed methods study was to identify participants' attributions for their global impression of change ratings in a behavioral intervention for unexplained chronic fatigue and chronic fatigue syndrome. At 3-month follow-up, participants (N = 67) were asked "Why do you think you are (improved, unchanged, worse)?" Improved patients pointed to specific behavioral changes, unchanged patients referred to a lack of change in lifestyle, and worsened patients invoked stress and/or specific life events. Identifying patient perceptions of behaviors associated with patient global impression of change-rated improvement and non-improvement may assist in developing more effective management strategies in clinical care.

ABSTRACT

BACKGROUND: Prolonged, severe, unalleviated fatigue may be disabling whether it occurs on its own or in conjunction with medical or psychiatric conditions. This paper compares the prevalence and correlates of prolonged fatigue in general population samples in Ukraine versus the U.S. METHODS: Population surveys were conducted in 2002 in both Ukraine (Ukraine World Mental Health [WMH] Survey) and the U.S. (National Comorbidity Survey-Replication; NCS-R). Both surveys administered the Composite International Diagnostic Interview (CIDI 3.0), which contained modules assessing: neurasthenia (prolonged fatigue); mood, anxiety, and alcohol/drug use disorders; chronic medical conditions; and demographic characteristics. Multivariable logistic regression was used to examine risk factors in each country. RESULTS: The lifetime prevalence of prolonged fatigue was higher in Ukraine (5.2%) than the U.S. (3.7%). In both countries, one-fifth of individuals with prolonged fatigue had no medical or DSM-IV psychiatric condition. Also in both settings, fatigue was significantly associated with sociodemographic characteristics (being female, not working, and married before) as well as early onset and adult episodes of mood/anxiety disorder. Fatigue prevalence in Ukraine increased with age, but decreased in the U.S. at age 70. Unique risk factors for fatigue in Ukraine included lower socio-economic status, Ukrainian vs Russian ethnicity, and cardiovascular disease. Unique risk factors in the U.S. were parental depression/anxiety, adult episodes of alcohol/drugs, pain conditions, and other health problems. CONCLUSIONS: The lifetime prevalence of prolonged fatigue in Ukraine was 40% higher than that found in U.S. data. In addition, fatigue prevalence increased sharply with age in Ukraine perhaps due to limited social and medical resources and greater comorbidity.

ABSTRACT

BACKGROUND: Fatigue is a common yet difficult to treat condition in primary care. The objective of this study is to evaluate the cost-effectiveness of a brief cognitive behavioral therapy (CBT) based fatigue self-management (FSM) intervention as compared to usual care among patients with chronic fatigue in primary care. METHODS: An economic evaluation alongside of a parallel randomized controlled study design was used. Computer-generated variable-sized block randomization plan was used to assign patients into treatment groups and data collection staff were blinded to group assignments. Patients aged between 18 and 65 years with at least six months of persistent fatigue and no medical or psychiatric exclusions were enrolled from a large primary care practice in Stony Brook, New York. The FSM group (n = 37) received two sessions of a nurse-delivered, fatigue self-management protocol and a self-help book and the usual care group (n = 36) received regular medical care. The effectiveness measure was the Fatigue Severity Scale and the cost measure was total health care expenditures derived from monthly health services use diaries during follow-up. A societal perspective was adopted and bootstrapped incremental cost-effectiveness ratios (ICERs) and net monetary benefit (NMB) were calculated as measures of cost-effectiveness. RESULTS: The ICER for FSM was -$$2358, indicating that FSM dominates UC and it may generate societal cost savings as compared to usual care. Complete case analysis yielded smaller ICER (-$1199) with greater uncertainties. Net monetary benefit analysis showed that FSM has a probability of 0.833 (95% CI: 0.819, 0.847) to achieve positive NMB and the favorable results were not sensitive to assumptions about informal care or treatment costs. CONCLUSION: This economic evaluation found initial evidence that a two-session brief CBT-based FSM may be cost-effective as compared to usual care over 12 months. The FSM intervention is potentially a promising intervention for chronic fatigue patients in primary care. Additional research is needed to examine the reproducibility and generalizability of these findings. TRIAL REGISTRATION: ClinicalTrials.gov (NCT00997451, March 28, 2009).

ABSTRACT

PURPOSE: In chronic fatigue syndrome (CFS), the lack of consensus on how recovery should be defined or interpreted has generated controversy and confusion. The purpose of this paper was to systematically review, compare, and evaluate the definitions of recovery reported in the CFS literature and to make recommendations about the scope of recovery assessments. METHODS: A search was done using the MEDLINE, PubMed, PsycINFO, CINAHL, and Cochrane databases for peer review papers that contained the search terms "chronic fatigue syndrome" and "recovery," "reversal," "remission," and/or "treatment response." RESULTS: From the 22 extracted studies, recovery was operationally defined by reference with one or more of these domains: (1) pre-morbid functioning; (2) both fatigue and function; (3) fatigue (or related symptoms) alone; (4) function alone; and/or (5) brief global assessment. Almost all of the studies measuring recovery in CFS did so differently. The brief global assessment was the most common outcome measure used to define recovery. Estimates of recovery ranged from 0 to 66 % in intervention studies and 2.6 to 62 % in naturalistic studies. CONCLUSIONS: Given that the term "recovery" was often based on limited assessments and less than full restoration of health, other more precise and accurate labels (e.g., clinically significant improvement) may be more appropriate and informative. In keeping with common understandings of the term recovery, we recommend a consistent definition that captures a broad-based return to health with assessments of both fatigue and function as well as the patient's perceptions of his/her recovery status.

ABSTRACT

OBJECTIVE: To assess the efficacy of brief fatigue self-management (FSM) for medically unexplained chronic fatigue (UCF) and chronic fatigue syndrome (CFS) in primary care. METHODS: A randomized controlled design was used wherein 111 patients with UCF or CFS were randomly assigned to two sessions of FSM, two sessions of symptom monitoring support (attention control; AC), or a usual care control condition (UC). Participants were assessed at baseline and at 3 and 12 months after treatment. The primary outcome, the Fatigue Severity Scale, measured fatigue impact on functioning. Analysis was by intention to treat (multiple imputation) and also by per protocol. RESULTS: A group × time interaction across the 15-month trial showed significantly greater reductions in fatigue impact in the FSM group in comparison with the AC group (p < .023) and the UC group (p < .013). Medium effect sizes for reduced fatigue impact in the FSM group were found in comparison with the AC group (d = 0.46) and the UC group (d = 0.40). The per-protocol analysis revealed large effect sizes for the same comparisons. Clinically significant decreases in fatigue impact were found for 53% of participants in the FSM condition, 14% in the AC condition, and 17% in the UC condition. Dropout rates at the 12-month follow-up were high (42%-53%), perhaps attributable to the burden of monthly telephone calls to assess health care use. CONCLUSION: A brief self-management intervention for patients with UCF or CFS seemed to be clinically effective for reducing the impact of fatigue on functioning.

ABSTRACT

Fibromyalgia (FM) is a persistent and disabling widespread pain condition often accompanied by chronic fatigue, cognitive problems, sleep disturbance, depression, anxiety, and headache. To date, the most thoroughly studied non-pharmacological approaches to managing FM are those with a focus on changing patient activities and beliefs that affect the illness. These interventions are intended to facilitate enduring improvement in pain and functional status. Lifestyle-oriented treatments include patient education, aerobic or other physical exercise, and cognitive-behavioral therapy (CBT). These interventions in FM can be delivered in medical or behavioral health care settings by trained professionals, through patient-oriented treatment manuals, or via remote-access technologies. Non-pharmacological treatments, in particular exercise and CBT, have yielded effect sizes and cost-benefit ratios comparable to medications. This paper describes lifestyle-oriented non-pharmacological treatments for FM and highlights selected literature reviews of these interventions. In addition, behavioral and practical issues are addressed that may affect these non-pharmacological treatments, including patient expectations, participant burden, and treatment availability. Recommendations are made to facilitate these interventions and potentially improve outcomes. In particular, the increasing availability of convenient home-based mobile technologies to deliver these non-pharmacological treatments is described.

ABSTRACT

BACKGROUND: The Script Concordance test (SCT) measures clinical reasoning in the context of uncertainty by comparing the responses of examinees and expert clinicians. It uses the level of agreement with a panel of experts to assign credit for the examinee's answers. AIM: This study describes the development and validation of a SCT for pre-clinical medical students. METHODS: Faculty from two US medical schools developed SCT items in the domains of anatomy, biochemistry, physiology, and histology. Scoring procedures utilized data from a panel of 30 expert physicians. Validation focused on internal reliability and the ability of the SCT to distinguish between different cohorts. RESULTS: The SCT was administered to an aggregate of 411 second-year and 70 fourth-year students from both schools. Internal consistency for the 75 test items was satisfactory (Cronbach's alpha = 0.73). The SCT successfully differentiated second- from fourth-year students and both student groups from the expert panel in a one-way analysis of variance (F(2,508) = 120.4; p < 0.0001). Mean scores for students from the two schools were not significantly different (p = 0.20). CONCLUSION: This SCT successfully differentiated pre-clinical medical students from fourth-year medical students and both cohorts of medical students from expert clinicians across different institutions and geographic areas. The SCT shows promise as an easy-to-administer measure of "problem-solving" performance in competency evaluation even in the beginning years of medical education.

ABSTRACT

Persons with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) often complain of fatigue states (eg, postexertional malaise, brain fog) that are qualitatively different than normal, daily fatigue. Given the heterogeneous nature of ME/CFS, it is likely that individuals with this illness experience these fatigue types differently in terms of severity and frequency. It is also possible that meaningful subgroups of patients exist that exhibit different patterns of the fatigue experience. The purpose of this study was to investigate whether individuals with ME/CFS can be classified in a meaningful way according to the different types of fatigue they experience. One hundred individuals with ME/CFS participated in the study. Individuals that met inclusion criteria were administered the Multiple Fatigue Types Questionnaire (MFTQ), a 5-factor instrument that distinguishes between different types of fatigue. A cluster analysis was used to classify patients into various clusters based on factor subscale scores. Using a 3-factor solution, individuals were classified according to illness severity (low, moderate, severe) across the different fatigue factors. However, a 5-cluster solution enabled participants with moderate to severe fatigue levels to fall into more differentiated clusters and demonstrate distinct fatigue state patterns. These results suggest that fatigue patterns of individuals with ME/CFS are heterogeneous, and that patients may be classified into meaningful subgroups.
