Physical activity, emotional stress, sleep disturbances, and daily fluctuations in chronic fatigue symptomatology

The current study explored the relationships between physical and emotional stress and the symptomatology of chronic fatigue syndrome (CFS). Fifty-four CFS patients were studied using a longitudinal design. A self-report format was used to collect daily measures of major physical (sleep disturbance and physical activity) and emotional (subjective emotional stress level) stressors, as well as measures of levels of fatigue and secondary symptoms. The variables accounted for a moderate variance at the individual and occasion levels. Sleep disturbance and emotional stress were found to be positively associated with levels of fatigue and symptomatology, whereas physical activity was found to have a negative relationship with fatigue only. The severity of fatigue and symptoms were found to fluctuate daily in relation with the variables, indicating the complex nature of the associations.

Rationale and design of the national benchmarking and evidence-based national clinical guidelines for chronic heart failure management programs study

OBJECTIVES: The National Benchmarks and Evidence-Based National Clinical Guidelines for Heart Failure Management Programs Study is a national, multicenter study designed to determine the nature, range, and effect of interventions applied by chronic heart failure management programs (CHF-MPs) throughout Australia on patient outcomes. Its primary objective is to use these data to develop national benchmarks and evidence-based clinical guidelines and optimize their cost-effective application by reducing quality and outcome variability. DATA SOURCES/STUDY SETTING: Primary data will be collected from CHF-MP coordinators and CHF patients enrolled in these programs on a national basis. Secondary outcome data will be collected from a national morbidity record and from patients' medical records. STUDY DESIGN: Stage I of the study involves a prospective clinical audit of all CHF-MPs throughout Australia (n = 45) to determine the extent of variability in programs currently. Stage II is a prospective cross-sectional survey design enrolling 1,500 patients (average of 40 patients per program) to firstly determine the typical profile of patients being managed via a CHF-MP in Australia and, secondly, the subsequent morbidity and mortality during the 6-month follow-up. Outcome data will be subject to multivariate analysis to determine the key components of care in this regard. All study data will be then examined in the final stage of the study (III) to develop national benchmarks for the application and auditing of CHF-MPs in Australia. CONCLUSION: Variability in patient outcomes is a product of heterogeneity among CHF-MPs. The development of national benchmarks will minimize such heterogeneity and will provide a greater level of evidence for their cost-effective application.

The impact of chronic illness on relationships in early adulthood: a comparison study between healthy and arthritic young adults

While engaging in romantic relationships is regarded as a normative task during young adulthood, non-normative life events such as the emergence of chronic illness can mitigate against the successful negotiation of such tasks. Chronic illness brings with it a series of additional challenges and stressors to the realm of personal relationships that are thought to interrupt the development of normative interpersonal and intra-individual processes. However, few studies have examined how young adults faced with a chronic illness such as arthritis navigate romantic relationships and the consequences of illness and relationships on psychological adjustment. The aim of the study was to compare the relationship experiences of healthy young adults with those faced with arthritis. One hundred and nine young adults (M 23.01 years, SD 2.43) took part in the study. Of these participants 41 had been diagnosed with arthritis. A univariate MANOVA revealed arthritic young adults reported significantly more insecure attachment, lower levels of readiness for intimacy, and poorer relationship satisfaction compared to healthy young adults. Further correlational and regression analyses on the arthritic sample revealed psychological adjustment was related to arthritis severity, attachment and components of coping. Findings will be discussed in relation to attachment theory and coping processes.

The limits of medicine and the social consequences for sufferers of chronic fatigue syndrome

Chronic fatigue syndrome (CFS) appears to be made up of several clusters of illness categories acting alone or in tandem to cause the decline of health through; fatigue/exhaustion, sensitivity/allergies, pain, general muscle and joint pains, cognitive impairment and gastrointestinal problems. This study investigated how patients interpret, evaluate and respond to the complex and varied symptoms of chronic fatigue syndrome. Data were collected from persons with CFS using a survey (n=90) and an interview (n=45). The researchers investigated how chronic fatigue syndrome is diagnosed by medical practitioners, how the label of CFS is determined and the social consequences for the patient. The results confirm the limited ability of the biomedical paradigm to diagnose adequately and treat effectively 'socially constructed' and medically ambiguous illnesses like CFS. In the absence of a legitimated regime of medical treatment for CFS, a range of often expensive treatments are employed by CFS sufferers, from formal use of pharmaceutical drugs through to 'alternative' therapies, including herbal, vitamin, homeopathic, esoteric meditative techniques, spiritual healing and general counselling are taken in no particular order.

Working mothers of children with chronic illness: narratives of working and caring

This paper reports the initial findings of an exploratory, qualitative study of the life and work of people who are working full-time and also caring for a child with chronic illness. The demands of such a lifestyle are significant. Respondents - all women - often reported 'doing-it-all' while constantly being frustrated and challenged in their mothering role.

Investigating socio-economic status and chronic illness: directions and dilemmas

In Australia, chronic illness is increasing being recognised as more important. Yet there is relatively little discussion of the nature of the role played by socio-economic status (SES) plays in its prevalence. This paper argues there are two effects of SES. The first is that lower SES can lead to an increase in chronic illness, as evidenced by a number of epidemiological studies. The second is that chronic illness can contribute to lower SES. Examples are provided of the different types of relationships. Difficulties associated with SES analyses and its relationship to chronic illness are discussed, and specific conditions such as HIV/AIDS are referred to as examples. In addition the work of Marmot on SES and chronic illness is drawn on. The authors identify a number of areas that require further research, and recommend that in studies of chronic illness, SES may be a contributing variable, and outcome, or both.

Towards ending the silence: working women as carers of children with chronic illness/disability

This research presents stories from Australian women who work and care for a child with a significant chronic illness or disability. The paper considers the theory of Silencing the Self (Jack, 1991) in relation to the reported experiences and behaviours of these women. We report three themes of Caring and Working: "Otherness", "Doing it All" - but "Wanting to Live a Normal Life". As in Jack's study, these women engaged in silencing of the self. However, we also observed other people contributing to their silence and, unlike the respondents in Jack's study, many of these women fought the silence and did not accept that their unhappy situations should continue. They sought a life where silencing may not have been necessary.

The extent and breadth of benefits from participating in chronic disease self-management courses: a national patient-reported outcomes survey

Objective
To quantify the benefits that people receive from participating in self-management courses and identify subgroups that benefit most.

Methods
People with a wide range of chronic conditions attending self-management courses (N = 1341 individuals) were administered the Health Education Impact Questionnaire (heiQ). Baseline and follow-up data were collected resulting in 842 complete responses. Outcomes were categorized as substantial improvement (effect size, ES ≥ 0.5), minimal/no change (ES −0.49 to 0.49) and substantial decline (ES ≤ −0.5).

Results
On average, one third of participants reported substantial benefits at the end of a course and this ranged from 49% in the heiQ subscale Skill and technique acquisition to 27% in the heiQ subscale Health service navigation. Stratification by gender, age and education showed that younger participants were more likely to benefit, particularly young women. No further subgroup differences were observed.

Conclusion
While the well-being of people with chronic diseases tends to decline, about one third of participants from a wide range of backgrounds show substantial improvements in a range of skills that enable them to self-manage.

Practice implications
These data support the application of self-management courses indicating that they are a useful adjunct to usual care for a modest proportion of attendees.

Muscle atrophy and hypertrophy signaling in patients with chronic obstructive pulmonary disease

Rationale: The molecular mechanisms of muscle atrophy in chronic obstructive pulmonary disease (COPD) are poorly understood. In wasted animals, muscle mass is regulated by several AKT-related signaling pathways.
Objectives: To measure the protein expression of AKT, forkhead box class O (FoxO)-1 and -3, atrogin-1, the phosphophrylated form of AKT, p70^S6K glycogen synthase kinase-3ß (GSK-3ß), eukaryotic translation initiation factor 4E binding protein-1 (4E-BP1), and the mRNA expression of atrogin-1, muscle ring finger (MuRF) protein 1, and FoxO-1 and -3 in the quadriceps of 12 patients with COPD with muscle atrophy and 10 healthy control subjects. Five patients with COPD with preserved muscle mass were subsequently recruited and were compared with six patients with low muscle mass.
Methods: Protein contents and mRNA expression were measured by Western blot and quantitative polymerase chain reaction, respectively.
Measurements and Main Results: The levels of atrogin-1 and MuRF1 mRNA, and of phosphorylated AKT and 4E-BP1 and FoxO-1 proteins, were increased in patients with COPD with muscle atrophy compared with healthy control subjects, whereas atrogin-1, p70^S6K, GSK-3ß, and FoxO-3 protein levels were similar. Patients with COPD with muscle atrophy showed an increased expression of p70^S6K, GSK-3ß, and 4E-BP1 compared with patients with COPD with preserved muscle mass.
Conclusions: An increase in atrogin-1 and MuRF1 mRNA and FoxO-1 protein content was observed in the quadriceps of patients with COPD. The transcriptional regulation of atrogin-1 and MuRF1 may occur via FoxO-1, but independently of AKT. The overexpression of the muscle hypertrophic signaling pathways found in patients with COPD with muscle atrophy could represent an attempt to restore muscle mass.

Attachment bonding and the receipt of care in the face of chronic illness

The relationship between social support and the mental health outcomes of chronic illness sufferers is regarded as complex with inconsistent findings across studies. More recently, researchers have argued that that these inconsistencies may be explained by attachment theory. In this preliminary study, we explored how attachment bonds with three distinct attachment figures – parents, best friends and romantic partners influenced arthritic young adults’ seeking of care. Forty-one arthritis sufferers aged between 18 and 33 years were administered an online questionnaire which included measures of attachment and the receipt of emotional and instrumental care. Significant differences were found in young adults’ attachment avoidance and anxiety ratings, and seeking of instrumental care across parents, best friends and romantic partners. These differences were associated with differences in the frequency and type of care received by young arthritis sufferers across the three attachment figures. Furthermore, arthritis severity was associated with the receipt of care from attachment figures however this relationship was partially mediated by attachment anxiety.

Automated attention flags in chronic disease care planning

Objectives: To assess the value of computerised decision support in the management of chronic respiratory disease by comparing agreement between three respiratory specialists, general practitioners (care coordinators), and decision support software.
Methods: Care guidelines for two chronic obstructive pulmonary disease projects of the SA HealthPlus Coordinated Care Trial were formulated. Decision support software, Care Plan On-Line (CPOL), was created to represent the intent of these guidelines via automated attention flags to appear in patients' electronic medical records. For a random sample of 20 patients with care plans, decisions about the use of nine additional services (eg,.smoking cessation, pneumococcal vaccination) were compared between the respiratory specialists, the patients' GPs and the CPOL attention flags.
Results: Agreement among the specialists was at the lower end of moderate (intraclass correlation coefficient [ICC], 0.48; 95% CI, 0.39-0.56), with a 20% rate of contradictory decisions. Agreement with recommendations of specialists was moderate to poor for GPs (le, 0.49; 95% CI, 0.33-0.66) and moderate to good for CPOL (K, 0.72; 95% CI, 0.55-0.90). CPOL agreement with GPs was moderate to poor (le, 0.41; 95% CI, 0.24-0.58). GPs were less likely than specialists or CPOL to decide in favour of an additional service (P< 0.001). CPOL was 87% accurate as an indicator of specialist decisions. It gave a 16% false-positive rate according to specialist decisions, and flagged 61% of decisions where GPs said No and specialists said Yes.
Conclusions: Automated decision support may provide GPs with improved access to the intent of guidelines; however, further investigation is required.
