Using Data Mining and Time Series to Investigate ME and CFS Naming Preferences

Abstract:

There have been numerous iterations of naming convention specified for Myalgic Encephalomyelitis (ME) and Chronic Fatigue Syndrome (CFS). As health care turns to “big data” analytics to gain insights, the Google Trends database was mined to ascertain worldwide trends of public interest in several ME- and CFS-related search categories between 2004 and 2019.
Time series analysis revealed that though “Chronic Fatigue Syndrome” remains the predominant search category in the ME and CFS field, the interest index declined at a rate of 2.77 per month during the 15-year study period. In the same time period, the interest index in “ME/CFS Hybrid” terms increased at a rate of 3.20 per month. Potential causal mechanisms for these trends and implications for patient sentiment analysis are discussed.

Epistemic in/justice in patient participation. A discourse analysis of the Dutch ME/CFS Health Council advisory process

Abstract:

In healthcare settings, patient participation is increasingly adopted as a possible remedy to ill people suffering from ‘epistemic injustices’ – that is to their unfair harming as knowers. In exploring and interpreting patient participation discourses within the 2013-2018 Dutch Myalgic Encephalomyelitis (ME)/Chronic Fatigue Syndrome (CFS) Health Council advisory process, this paper assesses the epistemological emancipatory value of this participatory practice. It reveals that in the analysed case, patient representatives predominantly offer biomedical knowledge about ME/CFS. They frame this condition as primarily somatic, and accordingly, perceive appropriate diagnostic criteria, research avenues and treatment options as quantifiable, objectifiable and explicitly non-psychogenic.

This paper argues that such a dominant biomedical patient participatory practice is ambiguous in terms of its ability to correct epistemic injustices towards ill people. Biomedicalized patient participation may enhance people’s credibility and their ability to make sense of their illness, but it may also undermine their valid position within participatory practices as well as lead to (sustaining) biased and reductive ideas about who ill people are and what kind of knowledge they hold. The final section of this paper offers a brief reflection on how to navigate such biomedicalized participatory practices in order to attain more emancipatory ones.

Patients’ hopes for recovery from myalgic encephalomyelitis and chronic fatigue syndrome: Toward a “recovery in” framework

Abstract:

Objective: There is no consensus on recovery from myalgic encephalomyelitis and chronic fatigue syndrome, which has spawned debates when interpreting outcome research. Within these debates, the patient voice is often neglected. This study aimed to understand how patients conceptualize recovery – regarding the definition and possibility of recovery.

Method: We conducted in-depth, semi-structured interviews with 10 older (above age 50) female patients with myalgic encephalomyelitis or chronic fatigue syndrome. Data were analyzed using a deductive thematic analysis.

Results: Our sample viewed recovery as functioning without fear of relapse, returning to previous roles and identities, and achieving a sustained absence of symptoms. Participants expressed skepticism that reaching recovery from myalgic encephalomyelitis and chronic fatigue syndrome exists but working toward significant improvement through coping is a viable goal. Although many accepted they would never reclaim full functioning, participants continued to experience uncertainty about their future with unclear prognostic goals and limited treatment options.

Discussion: Recovery is more than just symptom reduction. Outcome research should incorporate well-being measures like identity, meaning and quality of life, and personal empowerment to enhance recovery definitions. When communicating treatment goals, providers might convey cautious optimism for complete symptom remission, while emphasizing that living a fulfilling life through effective coping strategies is possible.

Diagnosing Chronic Fatigue Syndrome in South Asians: Lessons from a Secondary Analysis of a UK Qualitative Study

Abstract:

BACKGROUND: Chronic fatigue syndrome/myalgic encephalitis (CFS/ME) is rarely diagnosed in South Asia (SA), although the symptoms of this condition are seen in the population. Lessons from UK based South Asian, Black and Minority Ethnic (BME) communities may be of value in identifying barriers to diagnosis of CFS/ME in SA.

OBJECTIVES: To explore why CFS/ME may not be commonly diagnosed in SA.

SETTINGS AND DESIGN: A secondary analysis of qualitative data on the diagnosis and management of CFS/ME in BME people of predominantly South Asian origin in the UK using 27 semi-structured qualitative interviews with people with CFE/ME, carers, general practitioners (GPs), and community leaders.

RESULTS: CFS/ME is seen among the BME communities in the UK. People from BME communities in the UK can present to healthcare practitioners with vague physical complaints and they can hold a biomedical model of illness. Patients found it useful to have a label of CFS/ME although some GPs felt it to be a negative label. Access to healthcare can be limited by GPs reluctance to diagnose CFS/ME, their lack of knowledge and patients negative experiences. Cultural aspects among BME patients in the UK also act as a barrier to the diagnosis of CFS/ME.

CONCLUSION: Cultural values and practices influence the diagnosis of CFS/ME in BME communities. The variations in the perceptions around CFS/ME among patients, carers, and health professionals may pose challenges in diagnosing CFS/ME in SA as well. Raising awareness of CFS/ME would improve the diagnosis and management of patients with CFS/ME in SA.

Views on the nature of chronic fatigue syndrome: content analysis

Abstract:

OBJECTIVES: Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), has provoked much controversy and led to arguments between the medical profession and patient organizations. A particular focus for debate is the categorization of the condition as physical or psychological in its nature. The aim of this study was to compare how the written media, patient organizations and medical authorities regard the illness.

DESIGN: Content analysis of newspaper articles, ME patient organization websites, and medical websites and textbooks were assessed by two independent assessors.

SETTING:Three national UK newspapers, UK ME websites, and UK medical websites and textbooks, were accessed during 2010.

PARTICIPANTS: 146 source files were scored from 36 patients’ organizations, 72 media articles and 38 medical authorities.

MAIN OUTCOME MEASURED: The overall opinion of an article or website was rated using a five point Likert scale, from ‘extremely psychological’ (scored as 1), ‘moderately psychological’ (2), ‘both psychological and physical’ (3), ‘moderately physical’ (4) or ‘extremely physical’ (5).

RESULTS: Eighty-nine percent (32 of 36) of ME patient organizations considered the illness to be physical, compared with 58% (42/72) of newspaper articles, and 24% (9/38) of medical authorities. Sixty-three percent (24/38) of medical authorities regarded the illness as both physical and psychological. The inter-group differences of the Likert scores were statistically significant (χ(2) = 27.37, 2 df, P < 0.001).

CONCLUSION: The considerable disagreement, particularly between ME patient organizations and medical authorities, may help to explain the gulf in understanding between doctors and patients and the consequent reluctance of some patients to engage in behavioural treatments.

How do patients interpret terms for medically unexplained symptoms?

Abstract:

OBJECTIVE: To investigate how primary care patients interpret the existing terminology used to describe medically unexplained symptoms; to contribute to the current academic discussion on unequivocal terminology.

DESIGN: Descriptive cohort study.

METHODS: We approached patients in the waiting rooms of two general medical practices in the city of Groningen and in the province of Drenthe. Based on a fictitious case, the patients were asked to assign connotations to a number of possible diagnoses for medically unexplained tiredness. The patients could choose from seven predetermined connotations. Among the diagnoses for medically unexplained tiredness were ‘functional fatigue’, ‘chronic fatigue syndrome’, ‘psychosomatic tiredness’, and ‘medically unexplained tiredness’. From the seven connotations, we labeled three connotations as being negative. When patients gave at least one negative connotation to a possible diagnosis, the diagnosis was labeled as ‘offensive’.

RESULTS: A total of 184 patients participated in the study. From the alternative diagnoses for medically unexplained tiredness, ‘psychosomatic tiredness’ had the most negative connotations: at least one negative connotation for 65 (35%) patients. ‘Chronic fatigue syndrome’ and ‘functional fatigue’ had the fewest negative connotations: at least one negative connotation for respectively 17 (9%) and 24 (13%) patients.

CONCLUSION: The terms ‘chronic fatigue syndrome’ and ‘functional fatigue’ were less offensive. Our results could imply that terms for medically unexplained tiredness that refer less to a psychological basis are most acceptable for the patient.

Metacognitive factors in chronic fatigue syndrome

Abstract:

Chronic fatigue syndrome (CFS), which is characterized by fatigue and flu-like symptoms that are not alleviated by rest, is a poorly understood condition and an often controversial diagnosis. Earlier research has indicated that general metacognitions are associated with the severity of symptoms in patients with CFS. In the current study, we aimed to determine whether specific metacognitive factors are implicated in CFS. Using the metacognitive profiling interview template we investigated the following: (1) whether patients held positive or negative metacognitions about conceptual processes; (2) what their goals with respect to engaging in these processes were; and (3) what indicated that it was appropriate to stop. We also examined attention focus when experiencing CFS symptoms, and its advantages and disadvantages.

Results showed that patients endorsed positive and negative metacognitions pertaining to conceptual processes. The goals of engaging in these processes were to identify the cause of, and devise strategies to cope with, symptoms. Patients were either unable to identify a stop signal for conceptual processing or identified an improvement in fatigue-related symptoms as representing the stop signal. Finally, patients reported that their attention focus when experiencing symptoms included distraction and monitoring of symptoms. Advantages to these strategies included symptom management, whereas disadvantages included an escalation of negative affect. The present findings provide preliminary evidence that specific metacognitive factors may be involved in CFS.

KEY PRACTITIONER MESSAGE: Metacognitive profiling that may aid assessment and conceptualisation of psychological distress in CFS.

A comparison of patients with chronic fatigue syndrome in two “ideologically” contrasting clinics

Abstract:

Aim of the present study was to compare chronic fatigue syndrome (CFS) patients, attending 2 “ideologically” contrasting clinics for CFS, on various patient and illness characteristics. Fifty-nine CFS patients of each clinic, located in Leuven and Brussels (Belgium), participated. Patients did not differ with regard to age, levels of fatigue, psychopathology, and self-efficacy. However, patients from the psychosocially-oriented clinic had a lower level of education, reported more progressive illness onset, and attributed their illness more to psychological causes.

Patients in the biologically-oriented clinic reported more pain, and showed higher levels of social functioning, motivation and vitality, as well as fewer limitations related to emotional problems. It is concluded that CFS patients attending the 2 clinics could not be distinguished along dualistic biological/psychosocial lines, but those reporting sudden illness onset and making somatic attributions were more likely to be represented in the biologically-oriented clinic.

Neuropsychological functioning, illness perception, mood and quality of life in chronic fatigue syndrome, autoimmune thyroid disease and healthy participants

Abstract:

BACKGROUND: This study attempted to longitudinally investigate neuropsychological function, illness representations, self-esteem, mood and quality of life (QoL) in individuals with chronic fatigue syndrome (CFS) and compared them with both healthy participants and a clinical comparison group of individuals with autoimmune thyroid disease (AITD).

METHOD: Neuropsychological evaluation was administered at two time points, five weeks apart. Twenty-one individuals with CFS, 20 individuals with AITD and 21 healthy participants were matched for age, pre-morbid intelligence, education level and socio-economic status (SES). All groups also completed measures of illness perceptions, mood, self-esteem and QoL at both time points.

RESULTS: The CFS group showed significantly greater impairment on measures of immediate and delayed memory, attention and visuo-constructional ability, and reported significantly higher levels of anxiety and depression. After controlling for the effects of mood, the CFS group still demonstrated significant impairment in attention. The CFS group also reported significantly lower self-reported QoL than the AITD and healthy participants. In terms of illness perceptions, the AITD group believed that their condition would last longer, that they had more treatment control over their condition, and reported less concern than the CFS group.

CONCLUSIONS: These results suggest that the primary cognitive impairment in CFS is attention and that this is not secondary to affective status. The lower treatment control perceptions and greater illness concerns that CFS patients report may be causally related to their affective status.

Chronic fatigue syndrome: the role of positivity to illness in chronic fatigue syndrome patients

Abstract:

Fifty-three chronic fatigue syndrome patients treated at a complementary medical centre were assessed over 12 months. Measures included the Chalder Fatigue scale, the General Health Questionnaire (GHQ) and positivity in illness (Silver Lining Questionnaire, SLQ). The SLQ measured at 6 and 9 months predicted (p < .01) mental (but not physical) fatigue at 12 months independently of current mental fatigue, initial mental fatigue, duration since diagnosis and time between start of treatment and entry to the study. The GHQ did not predict fatigue at any time point. The results suggest that a caring therapeutic intervention increases positive interpretations of illness prior to improvements in mental fatigue, but that positivity does not play a causal role in the reduction of fatigue.
