Swallowing beyond six years post (chemo)radiotherapy for head and neck cancer; a cohort study.

OBJECTIVE: The objective of this prospective study is to report on long-term swallowing outcomes in a group of head and neck cancer patients following (chemo) radiotherapy treatment, assess for changes over time and identify any predictor variables of outcome. MATERIALS AND METHODS: 42 survivors were assessed on four swallowing measures and followed up from pre-treatment to six years post 3D (chemo) radiotherapy. Measures included a swallowing specific QOL questionnaire, penetration-aspiration scale, dietary restrictions and a timed water swallow test. RESULTS: At six years, 71% reported swallowing difficulties on the questionnaire. One fifth of patients had aspiration, with a raised risk of chest infection. Seven percent required a laryngectomy for a dysfunctional larynx. Despite this, half the group reported having a normal diet. There was variation in the pattern of change between one and six years. A significant deterioration was only observed in the timed water swallow test (p < 0.0001). Larger radiotherapy volume predicted this outcome. None of the variables tested predicted outcome for the other three swallow measures. CONCLUSION: Patients continue to report swallowing difficulties at six years, with a proportion having persistent aspiration. Further work on identifying the risk factors associated with aspiration tolerance, aspiration pneumonia, prevention and management is warranted. Long-term dysphagia remains a significant and serious concern following (chemo) radiotherapy for HNC and swallowing outcomes should continue to be monitored over time.

Feasibility and acceptability of combining cognitive behavioural therapy techniques with swallowing therapy in head and neck cancer dysphagia.

BACKGROUND: Head and neck cancer squamous cell carcinoma (HNSSC) patients report substantial rates of clinically significant depression and/or anxiety, with dysphagia being a predictor of distress and poorer quality of life. Evidence-based dysphagia interventions largely focus on the remediation of physical impairment. This feasibility study evaluates an intervention which simultaneously uses a psychological therapy approach combined with swallowing impairment rehabilitation. METHODS: This prospective single cohort mixed-methods study, recruited HNSCC patients with dysphagia, from two institutions. The intervention combined Cognitive Behavioural Therapy with swallowing therapy (CB-EST), was individually tailored, for up to 10 sessions and delivered by a speech and language therapist. Primary acceptability and feasibility measures included recruitment and retention rates, data completion, intervention fidelity and the responsiveness of candidate outcome measures. Measures included a swallowing questionnaire (MDADI), EORTC-QLQH&N35, dietary restrictions scale, fatigue and function scales and the Hospital Anxiety and Depression Scale (HADS), administered pre-, post-CB-EST with three month follow-up and analysed using repeated measures ANOVA. Qualitative interviews were conducted to evaluate intervention processes. RESULTS: A total of 30/43 (70%) eligible patients agreed to participate and 25 completed the intervention. 84% were male, mean age 59 yrs. Patients were between 1 and 60 months (median 4) post-cancer treatment. All patients had advanced stage disease, treated with surgery and radiotherapy (38%) or primary chemoradiotherapy (62%). Pre to post CB-EST data showed improvements in MDADI scores (p = 0.002), EORTC-QLQH&N35 (p = 0.006), dietary scale (p < 0.0001), fatigue (p = 0.002) but no change in function scales or HADS. Barriers to recruitment were the ability to attend regular appointments and patient suitability or openness to a psychological-based intervention. CONCLUSIONS: CB-EST is a complex and novel intervention, addressing the emotional, behavioural and cognitive components of dysphagia alongside physical impairment. Preliminary results are promising. Further research is required to evaluate efficacy and effectiveness.

Autologous tolerogenic dendritic cells for rheumatoid and inflammatory arthritis.

OBJECTIVES: To assess the safety of intra-articular (IA) autologous tolerogenic dendritic cells (tolDC) in patients with inflammatory arthritis and an inflamed knee; to assess the feasibility and acceptability of the approach and to assess potential effects on local and systemic disease activities. METHODS: An unblinded, randomised, controlled, dose escalation Phase I trial. TolDC were differentiated from CD14+ monocytes and loaded with autologous synovial fluid as a source of autoantigens. Cohorts of three participants received 1×106, 3×106 or 10×106 tolDC arthroscopically following saline irrigation of an inflamed (target) knee. Control participants received saline irrigation only. Primary outcome was flare of disease in the target knee within 5 days of treatment. Feasibility was assessed by successful tolDC manufacture and acceptability via patient questionnaire. Potential effects on disease activity were assessed by arthroscopic synovitis score, disease activity score (DAS)28 and Health Assessment Questionnaire (HAQ). Immunomodulatory effects were sought in peripheral blood. RESULTS: There were no target knee flares within 5 days of treatment. At day 14, arthroscopic synovitis was present in all participants except for one who received 10×106 tolDC; a further participant in this cohort declined day 14 arthroscopy because symptoms had remitted; both remained stable throughout 91 days of observation. There were no trends in DAS28 or HAQ score or consistent immunomodulatory effects in peripheral blood. 9 of 10 manufactured products met quality control release criteria; acceptability of the protocol by participants was high. CONCLUSION: IA tolDC therapy appears safe, feasible and acceptable. Knee symptoms stabilised in two patients who received 10×106 tolDC but no systemic clinical or immunomodulatory effects were detectable. TRIAL REGISTRATION NUMBER: NCT01352858.

Head and neck cancer and dysphagia; caring for carers.

OBJECTIVES: A diagnosis of head and neck cancer (HNC) is a profound event for patients and family members who play a crucial role in their care. Eating and drinking difficulties affect patients' quality of life (QOL), but the impact on the carers' QOL has not been explored. This preliminary mixed method study reports on carer QOL over time and investigates the relationship with dysphagia. METHODS: Two hundred and eight HNC patients referred for (chemo)radiotherapy were asked to identify a carer and complete a health-related QOL and a swallowing QOL questionnaire at pre-treatment, 3 and 12 months post-treatment. Carers were given the Caregiver QOL-Cancer (CQOL-C) questionnaire at the same time points. A purposive sample of patient and carer dyads was observed over mealtimes and interviewed. RESULTS: Seventy per cent of carers returned a questionnaire at least once. There was no change in CQOL-C scores between pre-treatment and 3 months, but a significant improvement was found between 3 and 12 months post-treatment (p = 0.012). Patient-reported outcomes accounted for 52% of variance in carer QOL measurements (R(2) = 0.52, p < 0.001). Four themes emerged from the qualitative data food provision, monitoring, motivation and changes to lifestyle. CONCLUSIONS: Findings suggest a relationship between carer and patient QOL. Elsewhere, these two characteristics have been associated such that the greater the patients' physical care needs, the poorer the carers' and patients' QOL. Living with someone with dysphagia not only involves managing the physical swallowing difficulties but is also likely to impact on social activities such as participation in shared meals, leading to permanent lifestyle changes.

Functional abilities and continence: the use of proxy respondents in research involving older people.

As the use of proxy respondents is sometimes necessary in research involving older or disabled people it is important to assess the impact of this on research results. This study examined the concordance of proxy responses and index responses on questions concerning functional abilities and continence. Index respondents were women aged 65 years and older who were interviewed as part of a larger study of outcomes of fractured neck of femur, at 5 days post surgery. They were asked to nominate a proxy respondent who was interviewed using the same questions within a few days. Responses of proxy and index respondents were compared using percentage agreement and Kappa statistics. On questions regarding functional ability, proxy responses were found to be more reliable for personal care activities than for instrumental activities of daily living. This may be a result of questions concerning instrumental activities being somewhat more ambiguous and open to individual interpretation. Item non-response was low for all questions thus resulting in little missing data for proxy respondents. There was a tendency for more distant relationship and contact to produce better agreement, which is contrary to previous findings. Proxy responses were biased in the direction of an overestimation of functional incapacity and so researchers should be cautious in combining data from proxy and index respondents. Concordance was good for questions concerning urinary and faecal incontinence although non-response was higher than for functional ability questions. Concordance was not as great for more detailed questions concerning the timing and frequency of incontinence as these used graded response options, rather than simple yes/no responses.

Changes in reported dietary habit and exercise levels after an uncomplicated first myocardial infarction in middle-aged men.

Education of patients and their partners about appropriate lifestyle changes following myocardial infarction (MI) is a key element in rehabilitation; developing relevant educational strategies requires a knowledge of patient beliefs and attitudes. This paper reports findings from a survey of diet and exercise in a group of 153 middle-aged men who had suffered a first uncomplicated MI. Just over half of those questioned expressed a desire to change their diet post-MI; those who perceived their pre-morbid diet to be 'less healthy' were more likely to want to change. Significant changes in food consumption (towards a more healthy diet) were observed at 3 months post-MI. Patients were less likely to change their behaviour with respect to exercise, and few attained recommended levels of physical activity either pre- or post-MI. Patients held a number of misconceptions regarding the role of diet and exercise in predisposing to coronary heart disease, and the need for change in behaviour. Beliefs and behaviour change were only weakly associated with receipt of information and advice. The findings have important messages for the more appropriate targeting of information-provision during the period of rehabilitation.

The detection of blood on dental surgery surfaces and equipment following dental hygiene treatment.

The Kastle-Meyer technique, a forensic test for blood, has been employed to assess the frequency and potential routes of contamination by blood between patients, staff and equipment during routine dental hygiene treatment. Fifty treatment sessions were studied and units were cleaned between patients according to the current hospital protocol. The surfaces most frequently contaminated after treatment were the 3-in-1 syringe buttons (40%), protective bibs (22%), tap handles (20%), light handles (18%) and operating cart handles (16%). Following cleaning of the units, the surfaces remaining contaminated were the 3-in-1 syringes (10%), tap handles (4%) and cart handles (2%). Modifications to the cross-infection control protocol have been made to eliminate these sources of contamination.
