A randomised controlled trial comparing the effectiveness of tai chi alongside usual care with usual care alone on the postural balance of community-dwelling people with dementia: protocol for the TACIT trial (TAi ChI for people with demenTia).

BACKGROUND: Falls are a public health issue for the older adult population and more so for people with dementia (PWD). Compared with their cognitively intact peers, PWD are at higher risk of falls and injurious falls. This randomised controlled trial aims to test the clinical and cost effectiveness of Tai Chi to improve postural balance among community-dwelling PWD and to assess the feasibility of conducting a larger definitive trial to reduce the incidence of falls among PWD. METHODS: A 3-centre parallel group randomised controlled trial with embedded process evaluation. One hundred and fifty community-dwelling dyads of a person with dementia and their informal carer will be recruited and assessed at baseline and at six-month follow-up. Dyads will be randomised in a 1:1 ratio to either usual care or usual care plus a Tai Chi intervention for 20 weeks. The Tai Chi intervention will consist of weekly classes (45 min' Tai Chi plus up to 45 min for informal discussion, with up to 10 dyads per class) and home-based exercises (20 min per day to be facilitated by the carer). Home practice of Tai Chi will be supported by the use of behaviour change techniques with the Tai Chi instructor at a home visit in week 3-4 of the intervention (action planning, coping planning, self-monitoring, and alarm clock reminder) and at the end of each class (feedback on home practice). The primary outcome is dynamic balance measured using the Timed Up and Go test, coinciding with the end of the 20-week intervention phase for participants in the Tai Chi arm. Secondary outcomes for PWD include functional balance, static balance, fear of falling, global cognitive functioning, visual-spatial cognitive functioning, quality of life, and falls. Secondary outcomes for carers include dynamic balance, static balance, quality of life, costs, and carer burden. DISCUSSION: This trial is the first in the UK to test the effectiveness of Tai Chi to improve balance among PWD. The trial will inform a future study that will be the first in the world to use Tai Chi in a trial to prevent falls among PWD. TRIAL REGISTRATION: NCT02864056 .

New Zealand National GDM Guidelines: an alternative view of some good practice points.

The New Zealand Gestational Diabetes Mellitus (GDM) Guidelines, commissioned by the Ministry of Health, contains many good points, but several recommendations are creating controversy. This opinion piece discusses an alternative approach to early pregnancy screening for diabetes. We suggest that it is reasonable to refer women with an HbA1c ≥41 mmol/mol (5.9%) for further management, rather than the recommended referral threshold of ≥50 mmol/mol (6.7%). We also suggest that, for subsequent screening for GDM at 24-28 weeks' gestation, a 75 g oral glucose tolerance test should be offered rather than a 50 g glucose challenge test.

Use of removable support boot versus cast for early mobilisation after ankle fracture surgery: cost-effectiveness analysis and qualitative findings of the Ankle Recovery Trial (ART).

OBJECTIVES: To estimate the cost-effectiveness of using a removable boot versus a cast following ankle fracture from the National Health Service and Personal Social Services (NHS+PSS) payer and societal perspectives and explore the impact of both treatments on participants' activities of daily living. DESIGN: Cost-effectiveness analyses and qualitative interviews performed alongside a pragmatic multicentre randomised controlled trial. SETTING: Eight UK NHS secondary care trusts. PARTICIPANTS: 243 participants (60.5% female, on average 48.2 years of age (SD 16.4)) with ankle fracture. Qualitative interviews with 16 participants. Interventions removable air boot versus plaster cast 2 weeks after surgery weight bearing as able with group-specific exercises. PRIMARY AND SECONDARY OUTCOME MEASURES: Quality-adjusted life years (QALYs) estimated from the EQ-5D-5L questionnaire, costs and incremental net monetary benefit statistics measured 12 weeks after surgery, for a society willing-to-pay £20 000 per QALY. RESULTS: Care in the boot group cost, on average, £88 (95% CI £22 to £155) per patient more than in the plaster group from the NHS+PSS perspective. When including all societal costs, the boot saved, on average, £676 per patient (95% CI -£337 to £1689). Although there was no evidence of a QALY difference between the groups (-0.0020 (95% CI -0.0067 to 0.0026)), the qualitative findings suggest participants felt the boot enhanced their quality of life. Patients in the boot felt more independent and empowered to take on family responsibilities and social activities. CONCLUSIONS: While the removable boot is slightly more expensive than plaster cast for the NHS+PSS payer at 12 weeks after surgery, it reduces productivity losses and the need for informal care while empowering patients. Given that differences in QALYs and costs to the NHS are small, the decision to use a boot or plaster following ankle surgery could be left to patients' and clinicians' preferences.

Patient perspectives on the Poole PCT cancer genetics service.

Focussing on the primary care aspects of the Kenilworth model, the Poole Primary Care Trust (PCT) cancer genetics service has aimed to develop a high quality primary care-led service for the assessment and counselling of people concerned about their genetic risk of cancer. The service has been available through General Practitioner (GP) surgeries within the PCT since early 2006, and is delivered by Community Cancer Nurses as part of their role to provide proactive care and support to cancer patients, their families and the local population. Acting as a point of reference for cancer genetics at each practice, the nurses have supplied basic education to both health professionals and lay staff about the aims of the service and the genetic risk of cancer. Feedback from service users is one of the key elements of the Poole evaluation. This article is based on the views of some of the first patients referred. The patients consulted one of the cancer nurses between June and December 2006, and were interviewed by a researcher about their experience. The interviews focussed on the psychosocial aspects of the patients' experiences, which are less accessible through quantitative methods. The patients were encouraged to talk specifically and generally about their experiences, and described some of the feelings and emotions from the time of their referral onwards.

More than just ticking a box how patient and public involvement improved the research design and funding application for a project to evaluate a cycling intervention for hip osteoarthritis.

PLAIN ENGLISH SUMMARY: Involving patients and the public in research helps to ensure that research remains relevant, and has an impact on the people it aims to benefit. Funding bodies now require patients and the public to be involved at all stages of research. Patients and members of the public were involved from the outset in research into a cycling and education programme for hip osteoarthritis. A group discussion took place with six participants from a trial of the programme. The group provided feedback on several areas including the relevance of the research, how the researchers proposed to recruit patients, the research design, the programme itself (including what they liked/didn't like about it), and how the researchers could publicise the research findings. The feedback received was invaluable, and helped shape the entire research project and funding application. The cycling and education programme has been extended in line with comments received from the group. They also helped identify the best way of gathering information from research participants and had suggestions for sharing the results, both of which were incorporated into the funding application. Often involving patients and the public in research can be seen as a 'tick box' exercise. However, this example shows how crucial involving patients and the public in research design is. It also shows how the funding application was made stronger as a result of patient input. Researchers should be encouraged to work closely with patients and the public to ensure their research is of the highest quality. ABSTRACT: Background Involving patients and the public in research is an essential activity to ensure relevant, accessible, and appropriate research. There is increasing obligation from funding bodies on researchers to have well thought through plans for involving the public, and indeed it is often a condition for funding. Patient and public involvement activity in this project was conducted to inform a funding application to investigate the effectiveness of a cycling and education intervention in the treatment of hip osteoarthritis. Methods Six participants from a feasibility programme of the intervention attended a two-hour patient and public involvement consultation group to provide feedback on various aspects of the proposed research and intervention. During the consultation group, two independent facilitators followed a detailed plan formulated with the research team. Feedback was validated by the attendees via email following the consultation, and a report was issued to the research team. Further feedback on subsequent changes was sought via email and telephone with members of a Patient Advisory Group. Results The patient and public involvement consultation group provided invaluable feedback and suggestions which impacted on the design and quality of the research project and the intervention. Key changes to the intervention included extending the duration of the cycling programme from six to eight weeks, and inclusion of an exercise diary to promote adherence to the intervention. Key feedback regarding the design of the research and funding application included suggestions for methods of dissemination, and confirmation of the primary outcome measure. Conclusions Patient and public involvement was crucial to the design of the proposed research and intervention. It informed many aspects of the research design and made the funding application stronger as a result. Involving patients and the public in research is much more than an obligation, or 'tick box' exercise. It can change and improve research quality, which is crucial when answering questions that are meaningful and important to patients, and which leads to increased impact. Collaboration with patients and the public should be planned and reported from the conception of a research idea where the impact of such input can be considerable.

Emotional intelligence: its role in training.

The ability to manage your own emotions while interpreting other people's is a useful skill in any caring environment, yet emotional intelligence is often overlooked in training programmes. Incorporating it into the curriculum will give nurses greater understanding of themselves and the way they relate to others, enabling more effective interactions with patients. It will also equip them emotionally to deal with highly charged situations. The authors describe a model for nurse education that teaches and promotes emotional intelligence.

Genetic and in silico comparative mapping of the polyphenol oxidase gene in bread wheat (Triticum aestivum L.).

Polyphenol oxidases (PPOs) are involved in the time-dependent darkening and discolouration of Asian noodles and other wheat end products. In this study, a doubled haploid (DH) population derived from Chara (moderately high PPO activity)/WW2449 (low PPO activity) was screened for PPO activity based on L-DOPA and L-tyrosine assays using whole seeds. Both these assays were significantly genetically correlated (r = 0.91) in measuring the PPO activity in this DH population. Quantitative trait loci (QTLs) analysis utilising a skeleton map enabled us to identify a major QTL controlling PPO activity based on L-DOPA and L-tyrosine on the long arm of chromosome 2A. The simple sequence repeat (SSR) marker GWM294b explained over 82% of the line mean phenotypic variation from samples collected in both 2000 and 2003. Four SSR markers were validated for PPO linkage in genetically diverse backgrounds and proven to correctly predict the PPO activity in more than 92% of wheat lines. Physical mapping using deletion lines of Chinese Spring has confirmed the location of the GWM294b, GWM312 and WMC170 on chromosome 2AL, between deletion breakpoints 2AL-C to 0.85. In order to identify functional gene markers, data searches for alignments between rice BAC/PAC clones assembled on chromosome 1 and 4, chromosome 7, and (1) the wheat expressed sequence tags mapped in deletion bin (2AL-C to 0.85) and (2) the coding sequence of a previously cloned wheat PPO gene were made and found significant sequence similarities with the PPO gene or common central domain of tyrosinase. Available PPO gene sequences in the National Centre for Biotechnology Information (NCBI) database have revealed that there is a significant molecular diversity at the nucleotide and amino acid level in the wheat PPO genes.
