Keeping physically active with rheumatoid arthritis: semi-structured interviews to explore patient perspectives, experiences and strategies.

BACKGROUND: Regular physical activity is safe and beneficial for people with rheumatoid arthritis (RA) but the majority of people with RA are less active than the general population and have a higher risk of co-morbidities. Exploring strategies used by physically active people with RA could inform effective methods to support those who are less active. OBJECTIVE: To explore the perspectives, experiences and strategies employed by people with RA who successfully engage with regular physical activity. DESIGN: Individual semi-structured interviews and thematic analysis. PARTICIPANTS: A purposive sample of physically active people with RA. RESULTS: Twelve females and three males participated (mean age 56, range 29 to 80; mean disease duration 13 years, range 10 months to 46 years). Analysis revealed eight constructs clustered into three themes. Theme 1: 'the individual' incorporated constructs of symptoms, feelings and role; theme 2: 'management' incorporated medical and self-management; theme 3: 'physical activity' incorporated constructs of type of physical activity, including barriers or facilitators. Participants reported a long history of physical activity prior to diagnosis and good support networks. All participants recognised that physical activity was key to their RA management, acknowledged the benefits from engaging in physical activity and were able to overcome barriers. Participants had strong beliefs that physical function would decline without regular physical activity. CONCLUSIONS: People with RA who successfully maintain physical activity are motivated by a desire to manage symptoms, resist functional decline and maintain health and independence. These findings should be explored with a wider range of people with RA.

The experiences of women receiving brachytherapy for cervical cancer: A systematic literature review.

OBJECTIVES: To determine women's experiences of brachytherapy for cervical cancer. KEY FINDINGS: Nineteen studies were included for data extraction/synthesis. Twelve studies focussed on psychological issues, seven on pharmacological aspects of women's experiences. Themes of anxiety, distress, pain, informational needs and non-pharmacological interventions were found. Nine out of ten psychological studies described brachytherapy as a distressing experience causing anxiety and distress for most women. Non-pharmacological interventions were found to be effective and inexpensive adjuncts. Peri and post-operative pharmacological management was variable, but duration of procedure was an important factor. CONCLUSION: Brachytherapy for gynaecological cancer causes varying levels of pain, anxiety and distress. To improve women's experiences there needs to be better pain management, patient information and the development of non-pharmacological interventions. Future recommendations are to develop clinical support guidelines, audit the quality of services and develop effective interventions to improve women's experiences of brachytherapy for locally advanced cervical cancer.

A Personal Experience of Performing a Systematic Literature Review.

This paper describes the personal experience of two novice reviewers in developing and conducting a systematic litera¬ture review (SLR) in the field of medical ultrasound. The review was performed as part of a PhD study by the first author, which required the researcher to critically review all relevant studies in their specific research area. The review was conducted using a formal, scientific process and high¬lighted 20 relevant papers. Among the lessons learnt, undertaking an SLR was a time-consuming process. The search produced 1,987 papers, and screening the search yield was facilitated by using a pre-defined protocol. Extraction of data from each study was standardised and generated a 1-page summary of the key findings and methodology to facilitate comparisons of the included studies. The Critical Appraisal Skills Programme (CASP) tool was used for quality assessment. In the critical appraisal process, it is essential that reviewers have good baseline knowledge in the research subject, a solid under¬standing of the fundamentals of a robust research study including potential bias in research. With the great amount of information that a critical appraisal produces, good information management was key throughout the review to ensure the process was explicit and replicable and so that reviewers could justify their decisions. The methods and processes detailed in this report, as well as its lessons, are relevant to an SLR for any research subject.

Test-retest reliability and smallest detectable change of the Bristol Impact of Hypermobility (BIoH) questionnaire.

OBJECTIVE: The Bristol Impact of Hypermobility (BIoH) questionnaire is a patient-reported outcome measure developed in conjunction with adults with Joint Hypermobility Syndrome (JHS). It has demonstrated strong concurrent validity with the Short Form-36 (SF-36) physical component score but other psychometric properties have yet to be established. This study aimed to determine its test-retest reliability and smallest detectable change (SDC). DESIGN: A test-retest reliability study. SETTING: Participants were recruited from the Hypermobility Syndromes Association, a patient organisation in the United Kingdom. PATIENTS: Recruitment packs were sent to 1080 adults who had given permission to be contacted about research. MAIN OUTCOME MEASURES: BIoH and SF-36 questionnaires were administered at baseline and repeated two weeks later. An 11-point global rating of change scale (-5 to +5) was also administered at two weeks. Test-retest analysis and calculation of the SDC was conducted on 'stable' patients (defined as global rating of change -1 to +1). RESULTS: 462 responses were received. 233 patients reported a 'stable' condition and were included in analysis (95% women; mean (SD) age 44.5 (13.9) years; BIoH score 223.6 (54.0)). The BIoH questionnaire demonstrated excellent test-retest reliability (ICC 0.923, 95% CI 0.900-0.940). The SDC was 42 points (equivalent to 19% of the mean baseline score). The SF-36 physical and mental component scores demonstrated poorer test-retest reliability and larger SDCs (as a proportion of the mean baseline scores). CONCLUSION: The results provide further evidence of the potential of the BIoH questionnaire to underpin research and clinical practice for people with JHS.

Development and initial validation of the Bristol Impact of Hypermobility questionnaire.

OBJECTIVES: Stage 1 - to identify the impact of joint hypermobility syndrome (JHS) on adults; Stage 2 - to develop a questionnaire to assess the impact of JHS; and Stage 3 - to undertake item reduction and establish the questionnaire's concurrent validity. DESIGN: A mixed methods study employing qualitative focus groups and interviews (Stage 1); a working group of patients, clinicians and researchers, and 'think aloud' interviews (Stage 2); and quantitative analysis of questionnaire responses (Stage 3). SETTING: Stages 1 and 2 took place in one secondary care hospital in the UK. Members of a UK-wide patient organisation were recruited in Stage 3. PARTICIPANTS: In total, 15, four and 615 participants took part in Stages 1, 2 and 3, respectively. Inclusion criteria were: age ≥18 years; diagnosis of JHS; no other conditions affecting physical function; able to give informed consent; and able to understand and communicate in English. INTERVENTIONS: None. MAIN OUTCOME MEASURES: The development of a questionnaire to assess the impact of JHS. RESULTS: Stage 1 identified a wide range of impairments, activity limitations and participation restrictions In Stage 2, a draft questionnaire was developed and refined following 'think aloud' analysis, leaving 94 scored items. In Stage 3, items were removed on the basis of low severity and/or high correlation with other items. The final Bristol Impact of Hypermobility (BIoH) questionnaire had 55 scored items, and correlated well with the physical component score of the Short Form 36 health questionnaire (r=-0.725). CONCLUSIONS: The BIoH questionnaire demonstrated good concurrent validity. Further psychometric properties need to be established.

Deep vein thrombosis resolution, recurrence and post-thrombotic syndrome: a prospective observational study protocol.

BACKGROUND: Reasons for the variation in response of deep vein thrombosis (DVT) to anticoagulation treatment are not known. Some patients develop complications such as post-thrombotic syndrome or recurrent DVT but others make a full recovery. The aim of the study is to identify the level of variation in response to anticoagulation treatment and provide more precise and quantitative disease characterisation in response to treatment. METHODS: A prospective observational study using duplex ultrasound to examine changes in thrombus characterisation, evolution and resolution over a 2 year period in patients with a confirmed DVT. Logistic regression analysis will be used to seek associations between characteristics present at baseline and the outcomes of DVT resolution, recurrence and the development of post-thrombotic syndrome (PTS). DISCUSSION: This research into the response to treatment of lower limb DVT and predictive factors for DVT resolution, recurrence and PTS could inform a more tailored approach to anticoagulation therapy for the future management of DVT.

Exercise for the management of cancer-related fatigue in adults.

BACKGROUND: Cancer-related fatigue is now recognised as an important symptom associated with cancer and its treatment. A number of studies have investigated the effects of physical activity in reducing cancer-related fatigue with no definitive conclusions regarding its effectiveness. OBJECTIVES: To evaluate the effect of exercise on cancer-related fatigue both during and after cancer treatment. SEARCH STRATEGY: The Cochrane Controlled Trials Register (CENTRAL/CCTR), MEDLINE (1966 to July 2007), EMBASE (1980 to July 2007), CINAHL (1982 to July 2007), British Nursing Index (January 1984 to July 2007), AMED (1985 to July 2007), SIGLE (1980 to July 2007), and Dissertation Abstracts International (1861 to July 2007) were all searched using key words. Reference lists off all studies identified for inclusion and relevant reviews were also searched. In addition, relevant journals were hand searched and experts in the field of cancer-related fatigue were contacted. SELECTION CRITERIA: Randomised controlled trials (RCTs) that investigated the effect of exercise on cancer-related fatigue in adults were included. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the methodological quality of studies and extracted data based upon predefined criteria. Where data were available meta-analyses were performed for fatigue using a random-effects model. MAIN RESULTS: Twenty-eight studies were identified for inclusion (n = 2083 participants), with the majority carried out on participants with breast cancer (n = 16 studies; n = 1172 participants). A meta-analysis of all fatigue data, incorporating 22 comparisons provided data for 920 participants who received an exercise intervention and 742 control participants. At the end of the intervention period exercise was statistically more effective than the control intervention (SMD -0.23, 95% Confidence Interval (CIs) -0.33 to -0.13). AUTHORS' CONCLUSIONS: Exercise can be regarded as beneficial for individuals with cancer-related fatigue during and post cancer therapy. Further research is required to determine the optimal type, intensity and timing of an exercise intervention.

Cancer-related fatigue: A critical appraisal.

This aim of this systematic review was to determine the prevalence and pattern of cancer-related fatigue (CRF), and identify factors associated with its development. Relevant literature was identified through an electronic database search using specified keywords. Included studies investigated CRF in adult cancer patients using a multidimensional fatigue measure. The methodological quality was assessed using six published standards. CRF is apparent both during and after anti-cancer therapy, however, the prevalence of CRF varied between studies. The variables associated with the development and persistence of CRF remain to be identified. Inconsistencies were evident in the pattern of CRF and its associated factors. This is likely to have arisen from the inherent difficulties in the measurement of a subjective sensation, further complicated by the myriad of outcome measures used. More methodologically sound research; assessing CRF from the commencement of therapy, considering all pertinent variables is needed.

Fatigue in gynaecological cancer patients: a pilot study.

RATIONALE: Fatigue is a frequent complaint of women with cancer. However, the incidence of fatigue has not been well studied, in particular gynaecological cancer, which despite its prevalence has received minimal investigation. GOALS OF WORK: The study aims were (1) to explore the symptoms experienced in a gynaecological cancer population, primarily fatigue and (2) to determine the acceptability of a fatigue questionnaire for use in a longitudinal survey. PATIENTS AND METHODS: Over the course of 1 month, women with gynaecological cancer attending a Regional Cancer Centre completed a demographic and symptom questionnaire and the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). MAIN RESULTS: Of the 32 individuals approached, 30 agreed to participate (mean age, 61 years; the most common treatment received was surgery followed by chemotherapy n=11; mean time from commencement of treatment, including surgery = 3 months). All participants completed the MFSI-SF. Tiredness was the most commonly reported symptom, experienced by 90% of subjects and the most frequently stated worst symptom, reported by 23.3%. Furthermore, 23 of 27 subjects reported that tiredness interfered completely with their daily living. The MFSI-SF mean total fatigue score was 14.4 (SD 15.9), ranging from -15 to 50. The possible total fatigue score ranges from -24 to 96. CONCLUSION: Despite the heterogeneous nature of the group, all participants completed the MFSI-SF. The study suggests that fatigue could be a problem for this population group. Thus, a longitudinal survey using the MFSI-SF to investigate the phenomenon further would appear feasible and justified.

Measuring disability in multiple sclerosis: is the Community Dependency Index an improvement on the Barthel Index?

The Community Dependency Index (CDI) was developed due to concerns that the Barthel Index (BI) was limited as a measure of physical function in community settings. However, no studies have compared the two rating scales within multiple sclerosis (MS). The aim of this study was to determine whether, in a community-based sample of people with MS, the CDI is a better measure than the BI. BI and CDI data were collected from 90 people with MS. Four measurement properties were compared: scaling assumptions (item mean scores, corrected item-total correlations), acceptability (score distributions, floor/ceiling effects), reliability (Cronbach's alpha) and validity (concurrent, discriminant, group differences, relative validity). Both scales satisfied recommended criteria for scaling assumptions (indicating it was legitimate to report a summed score) and internal consistency reliability (alpha > 0.85). The scales were highly correlated (r = 0.96), indicating they measured the same construct. Both scales demonstrated good group differences validity, but the BI was marginally superior. Notable ceiling effects (BI > CDI) were demonstrated for both scales, particularly in those less disabled. This study sample had relatively minor levels of disability, with over 70% still being independently mobile. In this sample of people with MS, the measurement properties of the BI and CDI examined were very similar, suggesting the CDI does not appear to have achieved its goal of better measurement.

A controlled study on the effects of transcutaneous electrical nerve stimulation and interferential therapy upon the RIII nociceptive and H-reflexes in humans.

OBJECTIVE: To study the effect of transcutaneous electrical nerve stimulation (TENS) and interferential therapy (IFT) upon the RIII nociceptive reflex and H-reflex. DESIGN: Double-blind conditions. PARTICIPANTS: Seventy healthy subjects were randomly allocated to one of seven groups (n = 10 per group): Control, TENS 1 (5 Hz), TENS 2 (100 Hz), TENS 3 (200 Hz), IFT 1 (5 Hz), IFT 2 (100 Hz), IFT 3 (200 Hz). INTERVENTION: In the treatment groups, stimulation was applied over the right sural nerve for 15 minutes. MAIN OUTCOME MEASURES: Ipsilateral RIII and H-reflexes were recorded before treatment, immediately after treatment, and subsequently at 25, 35, and 45 minutes. Subjects rated the pain associated with the RIII reflex using a computerized visual analogue scale (VAS). RESULTS: Statistical analysis using ANOVA showed no significant differences between baseline and posttreatment measurement for RIII reflex, H-reflex, or VAS data. CONCLUSION: These results suggest that neither type of electrical stimulation (TENS or IFT) affects the RIII or H-reflexes, at least using the parameters and application time in this study.
