  • THE IMPACT OF USING INTRAOPERATIVE ULTRASOUND ON SURGICAL RESECTION OF HIGH-GRADE GLIOMA: A SYSTEMATIC REVIEW AND META-ANALYSIS

    Christou, A (Neuroncology, 2022-09)
    BACKGROUND: Despite operative and adjuvant therapies, high-grade glioma (HGG) remains incurable, with the extent of surgical resection being one of the modalities that can improve patient survival. Enabling maximal safe and minimising post-operative neurological morbidity is a key aim of surgical resection. Numerous intraoperative surgical adjuncts are used at surgery and intraoperative ultrasound (IoUS), is one such adjunct. IoUS is a cost-effective, easy to use, repeatable surgical adjunct, safe for the patient and potentially available in all centres. Although it's commonly used, no up to date systematic review exists collating and quantifying the level of evidence, delineating its impact on the extent of surgical resection. MATERIAL AND METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The study was registered with the PROSPERO data- base (CRD42022300034). Keywords across Medline/PubMed and Embase between 1996 and November 2021 were used. We included articles with adult supratentorial, histopathologically confirmed HGG patients aimed for resection, evaluating the correlation of IoUS use and gross-total resection (GTR). Meta-analyses were conducted according to the statistical heterogeneity between the studies using the Open Meta Analyst software. RESULT(S): 2942 articles were identified of which 16 were qualitative assessed and 10 used for quantitative meta-analysis. In qualitative assessment, a mean 4.63/8 Newcastle-Ottawa-Scale score was found for studies with no cohorts (no use of IoUS) and a mean score of 6/9, for studies including exposed versus non-exposed cohorts. The RCT was of moderate quality according to the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tool. A pooled analysis across 10 studies of HGG aimed for resection with the use of IoUS, led to GTR achieved in 168/365 cases, resulting in an overall GTR rate of 51.1% (95% CI, 33.9%-68.3%, p<0.001), with great heterogeneity across studies (93.02% p<0.001). In a subgroup meta-analysis of 3 studies of HGG aimed for complete resection only, GTR was achieved in 43/62 cases, yielding a 72.7% GTR rate (95% CI 41.6%-100%, p<0.001) with significant heterogeneity across studies (I2 92.1%, p<0.001). In 4 case-controlled studies, a total of 43.6% (48/110) GTR rate was achieved when IoUS was used versus 24.7% (65/263) when IoUS was not used, resulting in an odds ratio = 2.009 (95% CI 1.157-3.490, p <0.001) for achieving GTR. CONCLUSION(S): The meta-analysis showed a high GTR rate (72.7%) when HGG were aimed for complete resection and a two-fold probability of achieving GTR when IoUS is used than not used.
  • Therapist differences in a randomised trial of the outcome of cognitive behaviour therapy for health anxiety in medical patients

    Lisseman-Stones, Yvonne (International Journal of Nursing Studies, 2015-03)
    Background: Health anxiety is common in medical settings and can be treated successfully by cognitive behaviour therapy. However it is not clear who might be best placed to deliver this therapy. Objectives: In a planned secondary analysis of data from a randomised trial of adapted cognitive behaviour therapy for health anxiety we compared outcomes of therapy delivered by nurses and other professional groups. Design: A randomised controlled trial with two treatment arms, 5-10 sessions of cognitive behaviour therapy adapted health anxiety or standard care. Setting: Cardiology, endocrine, gastroenterology, neurological and respiratory clinics in six general hospitals in the UK covering urban, suburban and rural areas. Participants: Medical patients attending the clinics who had pathological health anxiety and also scored for a diagnosis of hypochondriasis. Methods: Patients were randomised to one of two treatment arms, 5-10 sessions of cognitive behaviour therapy adapted health anxiety or standard care delivered by naive therapists (not randomised) who were trained in advance before delivering the treatment. Independent assessment of outcomes by researchers masked to allocation status at 3m, 6m, 12m and 24m. Results: 444 patients were randomised in the trial, 219 to cognitive behaviour therapy adapted health anxiety and 225 to standard care. 373 (84%) completed assessments after two years. Those treated by nurses (n=66) had improvement in health anxiety, generalised anxiety and depression outcomes that were significantly better and twice as great as those of the professional groups of assistant psychologists (n=87) and graduate workers (n=66) (P<0.01 over all time points). The number needed to treat to show superiority of nurse-delivered treatment over other treatment delivery was 4 at 6 months and 6 at one year. Conclusion: General nurses, after suitable training, are very effective therapists for patients with health anxiety in medical clinics and should be the therapists of choice for patients in these settings.
  • Patients' experiences of occupational therapy within a multidisciplinary pain management programme: A qualitative study

    Goodall, Jacqueline
    Background Occupational problems are common for adults experiencing chronic pain, but occupational therapists are not always accessed as part of the multidisciplinary team. Despite evidence of benefit for work-focused interventions, there is limited evidence for broader benefit from occupational therapy interventions within the context of multidisciplinary pain management. The aim of this study was to explore the experiences of programme attendees who received structured intervention from an occupational therapist as part of a multidisciplinary pain management programme, and gain an understanding as to how they felt it influenced changes they made to occupational participation. Method A qualitative approach was undertaken with 9 individual patients recruited from a group pain management programme for adults with chronic low back pain. Semi-structured interviews were carried out, recorded and transcribed. Thematic analysis was used to identify themes in the data. Results Three key themes were identified: 1) the helpfulness of activity pacing techniques 2) the value of participating in a therapeutic activity-based session and 3) an increased understanding of the importance of leisure and creative activities in the context of their lives. Conclusion Participants perceived the specific occupational therapy content of the programme to be helpful in a number of different ways. The findings suggest that occupational therapy can be important in facilitating patients to apply theoretical techniques in the real world, thereby increasing the likelihood of long term benefit.
  • Effectiveness of scapula-focused approaches in patients with rotator cuff related shoulder pain: A systematic review and meta-analysis

    West, Morgan (2016-09)
    Background: Rotator cuff related shoulder pain (RCSP) is common with a range of conservative treatments currently offered. Evidence supporting superiority of one approach over another is lacking. Scapula focused approaches (SFA) are frequently prescribed and warrant investigation. Objective: To evaluate the effectiveness of SFA in RCSP. Design: Systematic review of randomised controlled trials. Methods: An electronic search including MEDLINE, PEDro, ENFISPO to January 2016 was supplemented by hand searching. Randomised controlled trials were included; appraised using the PEDro scale and synthesised via meta-analysis or narratively, where appropriate. Results: Four studies (n = 190) reported on pain and three studies (n = 122) reported on disability. Regarding pain, there was statistical but not clinically significant benefit of SFA versus generalised approaches (mean difference (VAS) 0.714; 95% CI 0.402-1.026) in the short term (< 6 weeks); regarding disability, there was significant benefit of SFA versus generalised approaches (mean difference 14.0; 95% CI 11.2-16.8) in the short term (< 6 weeks). One study (n = 22) reported disability at 3 months, which was not statistically significant. Evidence is conflicting from four studies relating to the effect of SFA on scapula position/movement. Conclusion: SFA for RCSP confers benefit over generalised approaches up to six weeks but this benefit is not apparent by 3 months. Early changes in pain are not clinically significant. With regards to scapula position/movement, the evidence is conflicting. These preliminary conclusions should be treated with significant caution due to limitations of the evidence base.

  • Patients' Use of a Home-Based Virtual Reality System to Provide Rehabilitation of the Upper Limb Following Stroke.

    Platts, Fran (2015-03)
    Background: A low-cost virtual reality system that translates movements of the hand, fingers, and thumb into game play was designed to provide a flexible and motivating approach to increasing adherence to home-based rehabilitation. Objective: Effectiveness depends on adherence, so did patients use the intervention to the recommended level? If not, what reasons did they give? The purpose of this study was to investigate these and related questions. Design: A prospective cohort study, plus qualitative analysis of interviews, was conducted. Methods: Seventeen patients recovering from stroke recruited to the intervention arm of a feasibility trial had the equipment left in their homes for 8 weeks and were advised to use it 3 times a day for periods of no more than 20 minutes. Frequency and duration of use were automatically recorded. At the end of the intervention, participants were interviewed to determine barriers to using it in the recommended way. Results: Duration of use and how many days they used the equipment are presented for the 13 participants who successfully started the intervention. These figures were highly variable and could fall far short of our recommendations. There was a weak positive correlation between duration and baseline reported activities of daily living. Participants reported lack of familiarity with technology and competing commitments as barriers to use, although they appreciated the flexibility of the intervention and found it motivating. Limitations: The small sample size limits the conclusions that can be drawn. Conclusions: Level of use is variable and can fall far short of recommendations. Competing commitments were a barrier to use of the equipment, but participants reported that the intervention was flexible and motivating. It will not suit everyone, but some participants recorded high levels of use. Implications for practice are discussed.
  • Delivering an Optimised Behavioural Intervention (OBI) to people with low back pain with high psychological risk; results and lessons learnt from a feasibility randomised controlled trial of Contextual Cognitive Behavioural Therapy (CCBT) vs. Physiotherapy.

    OBI Trial Management Team (2015-06)
    Background: Low Back Pain (LBP) remains a common and costly problem. Psychological obstacles to recovery have been identified, but psychological and behavioural interventions have produced only moderate improvements. Reviews of trials have suggested that the interventions lack clear theoretical basis, are often compromised by low dose, lack of fidelity, and delivery by non-experts. In addition, interventions do not directly target known risk mechanisms. We identified a theory driven intervention (Contexual Cognitive Behavioural Therapy, CCBT) that directly targets an evidence-based risk mechanism (avoidance and ensured dose and delivery were optimised. This feasibility study was designed to test the credibility and acceptability of optimised CCBT against physiotherapy for avoidant LBP patients, and to test recruitment, delivery of the intervention and response rates prior to moving to a full definitive trial. Methods: A randomised controlled feasibility trial with patients randomised to receive CCBT or physiotherapy. CCBT was delivered by trained supervised psychologists on a one to one basis and comprised up to 8 one-hour sessions. Physiotherapy comprised back to fitness group exercises with at least 60 % of content exercise-based. Patients were eligible to take part if they had back pain for more than 3 months, and scored above a threshold indicating fear avoidance, catastrophic beliefs and distress. Results: 89 patients were recruited. Uptake rates were above those predicted. Scores for credibility and acceptability of the interventions met the set criteria. Response rates at three and six months fell short of the 75 % target. Problems associated with poor response rates were identified and successfully resolved, rates increased to 77 % at 3 months, and 68 % at 6 months. Independent ratings of treatment sessions indicated that CCBT was delivered to fidelity. Numbers were too small for formal analysis. Although average scores for acceptance were higher in the CCBT group than in the group attending physiotherapy (increase of 7.9 versus 5.1) and change in disability and pain from baseline to 6 months were greater in the CCBT group than in the physiotherapy group, these findings should be interpreted with caution. Conclusions: CCBT is a credible and acceptable intervention for LBP patients who exhibit psychological obstacles to recovery.
  • A low cost virtual reality system for home based rehabilitation of the arm following stroke: a randomised controlled feasibility trial

    Platts, Fran (2017-03)
    OBJECTIVE: To assess the feasibility of conducting a randomised controlled trial of a home-based virtual reality system for rehabilitation of the arm following stroke. DESIGN: Two group feasibility randomised controlled trial of intervention versus usual care. SETTING: Patients' homes. PARTICIPANTS: Patients aged 18 or over, with residual arm dysfunction following stroke and no longer receiving any other intensive rehabilitation. INTERVENTIONS: Eight weeks' use of a low cost home-based virtual reality system employing infra-red capture to translate the position of the hand into game play or usual care. MAIN MEASURES: The primary objective was to collect information on the feasibility of a trial, including recruitment, collection of outcome measures and staff support required. Patients were assessed at three time points using the Wolf Motor Function Test, Nine-Hole Peg Test, Motor Activity Log and Nottingham Extended Activities of Daily Living. RESULTS: Over 15 months only 47 people were referred to the team. Twenty seven were randomised and 18 (67%) of those completed final outcome measures. Sample size calculation based on data from the Wolf Motor Function Test indicated a requirement for 38 per group. There was a significantly greater change from baseline in the intervention group on midpoint Wolf Grip strength and two subscales of the final Motor Activity Log. Training in the use of the equipment took a median of 230 minutes per patient. CONCLUSIONS: To achieve the required sample size, a definitive home-based trial would require additional strategies to boost recruitment rates and adequate resources for patient support.
