RESUMO

Head-to-head comparisons of the efficacy of treatments for gastroenteropancreatic neuroendocrine tumours (GEP-NETs) have not yet been reported. This study used a series of matching-adjusted indirect comparisons to indirectly compare the effectiveness of [177Lu]Lu-DOTA-TATE to everolimus, sunitinib and best supportive care (BSC) for extending progression-free survival and overall survival in patients with advanced, unresectable gastrointestinal (GI)-NETs and P-NETs. The results of the main analysis suggest that after accounting for differences in key prognostic variables, the hazard of progression was 62% (hazard ratio [HR], 0.38; confidence interval [CI]95 0.25-0.58) and 65% (HR 0.35 CI95 0.21-0.59) lower in patients with GI-NETs treated with [177Lu]Lu-DOTA-TATE than in those treated with everolimus and BSC, respectively. Similarly, the hazard of progression was 64% (HR 0.36 CI95 0.18-0.70), 54% (HR 0.46 CI95 0.30-0.71) and 79-87% (HR 0.21 CI95 0.13-0.32; HR 0.13 CI95 0.08-0.22) lower in patients with P-NET treated with [177Lu]Lu-DOTA-TATE than in those treated with sunitinib, everolimus and BSC, respectively. The hazard of death was 58% (HR 0.42 CI95 0.25-0.72), 47% (HR 0.53 CI95 0.33-0.87) and 44-64% (HR 0.56 CI95 0.36-0.90; HR 0.34 CI95 0.20-0.57) lower in P-patients with NET treated with [177Lu]Lu-DOTA-TATE than in those treated with sunitinib, everolimus and BSC, respectively. While our results must be interpreted with caution given the non-randomised nature of the comparisons and the potential for residual confounding, the magnitude of the effect sizes we observe and their consistency across comparators suggest that [177Lu]Lu-DOTA-TATE may be a more effective treatment option than everolimus, sunitinib and BSC in advanced, unresectable GEP-NETs.

RESUMO

Background and Purpose- There is limited evidence to guide rehabilitation to meet the longer term needs of stroke survivors. The clinical effectiveness and cost-effectiveness of an extended stroke rehabilitation service (EXTRAS) provided following early supported discharge were determined. Methods- EXTRAS was a pragmatic parallel-group observer-blind randomized controlled trial involving 19 UK centers. Patients with stroke were individually randomized to receive EXTRAS or usual care at discharge from early supported discharge. Five EXTRAS reviews were provided by an early supported discharge team member between one and 18 months, usually by telephone. Reviews consisted of a semi-structured interview assessing progress, rehabilitation needs, and service provision, with goal setting and action planning. The primary outcome was performance in extended activities of daily living (Nottingham EADL Scale) at 24 months post-randomization. The Nottingham EADL Scale is scored 0 to 66, with higher scores indicating better performance in these activities. Cost-effectiveness was estimated using resource utilization costs and Quality Adjusted Life Years. Analyses were intention to treat. Results- Between January 9, 2013 and October 26, 2015, 573 participants were randomized (EXTRAS, n=285; usual care, n=288). Mean 24 month Nottingham EADL Scale scores were EXTRAS (n=219) 40.0 (SD 18.1) and usual care (n=231) 37.2 (SD 18.5) giving an adjusted mean difference of 1.8 (95% CI, -0.7 to 4.2). 1155/1338 (86%) of expected EXTRAS reviews were undertaken. Over 24 months, the mean cost of resource utilization was lower in the intervention group: -£311 (-$450 [95% CI, -£3292 to £2787; -$4764 to $4033]). EXTRAS provided more Quality Adjusted Life Years (0.07 [95% CI, 0.01 to 0.12]). At current conventional thresholds of willingness to pay (£20 000 [$28 940] per Quality Adjusted Life Years), there was a 90% chance that EXTRAS could be considered cost-effective. Conclusions- EXTRAS did not significantly improve stroke survivors' performance in extended activities of daily living. However, given the impact on costs and Quality Adjusted Life Years, EXTRAS may be an affordable addition to improve stroke care. Clinical Trial Registration- URL: www.isrctn.com.

RESUMO

BACKGROUND: Alcohol related hospital attendances are a potentially avoidable burden on emergency departments (EDs). Understanding the number and type of patients attending EDs with alcohol intoxication is important in estimating the workload and cost implications. We used best practice from previous studies to establish the prevalence of adult alcohol related ED attendances and estimate the costs of clinical management and subsequent health service use. METHODS: The setting was a large inner city ED in northeast England, UK. Data were collected via (i) retrospective review of hospital records for all ED attendances for four pre-specified weeks in 2010/2011 to identify alcohol related cases along with 12 months of follow-up of the care episode and (ii) prospective 24/7 assessment via breath alcohol concentration testing of patients presenting to the ED in the corresponding weeks in 2012/2013. RESULTS: The prevalence rates of alcohol related attendances were 12% and 15% for the retrospective and prospective cohorts, respectively. Prospectively, the rates ranged widely from 4% to 60% across week days, rising to over 70% at weekends. Younger males attending in the early morning hours at weekends made up the largest proportion of alcohol related attendances. The mean cost per attendance was £249 (SD £1064); the mean total cost for those admitted was £851 (SD £2549). The most common reasons for attending were trauma related injuries followed by psychiatric problems. CONCLUSIONS: Alcohol related attendances are a major and avoidable burden on emergency care. However, targeted interventions at weekends and early morning hours could capture the majority of cases and help prevent future re-attendance.

RESUMO

BACKGROUND: Clinicians' behaviours require deliberate decision-making in complex contexts and may involve both impulsive (automatic) and reflective (motivational and volitional) processes. PURPOSE: The purpose of this study was to test a dual process model applied to clinician behaviours in their management of type 2 diabetes. METHODS: The design used six nested prospective correlational studies. Questionnaires were sent to general practitioners and nurses in 99 UK primary care practices, measuring reflective (intention, action planning and coping planning) and impulsive (automaticity) predictors for six guideline-recommended behaviours: blood pressure prescribing (N = 335), prescribing for glycemic control (N = 288), providing diabetes-related education (N = 346), providing weight advice (N = 417), providing self-management advice (N = 332) and examining the feet (N = 218). RESULTS: Respondent retention was high. A dual process model was supported for prescribing behaviours, weight advice, and examining the feet. A sequential reflective process was supported for blood pressure prescribing, self-management and weight advice, and diabetes-related education. CONCLUSIONS: Reflective and impulsive processes predict behaviour. Quality improvement interventions should consider both reflective and impulsive approaches to behaviour change.

RESUMO

UNLABELLED: Behavioral theory is often tested on one behavior in isolation from other behaviors and theories. We aimed to test the predictive validity of constructs from motivation and action theories of behavior across six diabetes-related clinician behaviors, within the same sample of primary care clinicians. Physicians and nurses (n = 427 from 99 practices in the United Kingdom) completed questionnaires at baseline and 12 months. PRIMARY OUTCOMES: six self-reported clinician behaviors related to advising, prescribing and examining measured at 12 months; secondary outcomes: baseline intention and patient-scenario-based simulated behavior. Across six behaviors, each theory accounted for a medium amount of variance for 12-month behavior (median R adj (2)  = 0.15), large and medium amount of variance for two intention measures (median R adj (2)  = 0.66; 0.34), and small amount of variance for simulated behavior (median R adj (2)  = 0.05). Intention/proximal goals, self-efficacy, and habit predicted all behaviors. Constructs from social cognitive theory (self-efficacy), learning theory (habit) and action and coping planning consistently predicted multiple clinician behaviors and should be targeted by quality improvement interventions.

RESUMO

BACKGROUND: Type 2 diabetes is an increasingly prevalent illness, and there is considerable variation in the quality of care provided to patients with diabetes in primary care. OBJECTIVES: The aim of this study was to explore whether organizational justice and organizational citizenship behaviour are associated with the behaviours of clinical staff when providing care for patients with diabetes. METHODS: The data were from an ongoing prospective multicenter study, the 'improving Quality of care in Diabetes' (iQuaD) study. Participants (N = 467) were clinical staff in 99 primary care practices in the UK. The outcome measures were six self-reported clinical behaviours: prescribing for glycaemic control, prescribing for blood pressure control, foot examination, giving advice about weight management, providing general education about diabetes and giving advice about self-management. Organizational justice perceptions were collected using a self-administered questionnaire. The associations between organizational justice and behavioural outcomes were tested using linear multilevel regression modelling. RESULTS: Higher scores on the procedural component of organizational justice were associated with more frequent weight management advice, self-management advice and provision of general education for patients with diabetes. The associations between justice and clinical behaviours were not explained by individual or practice characteristics, but evidence was found for the partial mediating role of organizational citizenship behaviour. CONCLUSIONS: Quality improvement efforts aimed at increasing advice and education provision in diabetes management in primary care could target also perceptions of procedural justice.

RESUMO

BACKGROUND: In recent years, alongside the exponential increase in the prevalence of overweight and obesity, there has been a change in the food environment (foodscape). This research focuses on methods used to measure and classify the foodscape. This paper describes the foodscape across urban/rural and socio-economic divides. It examines the validity of a database of food outlets obtained from Local Authority sources (secondary level & desk based), across urban/rural and socio-economic divides by conducting fieldwork (ground-truthing). Additionally this paper tests the efficacy of using a desk based classification system to describe food outlets, compared with ground-truthing. METHODS: Six geographically defined study areas were purposively selected within North East England consisting of two Lower Super Output Areas (LSOAs; a small administrative geography) each. Lists of food outlets were obtained from relevant Local Authorities (secondary level & desk based) and fieldwork (ground-truthing) was conducted. Food outlets were classified using an existing tool. Positive predictive values (PPVs) and sensitivity analysis was conducted to explore validation of secondary data sources. Agreement between 'desk' and 'field' based classifications of food outlets were assessed. RESULTS: There were 438 food outlets within all study areas; the urban low socio-economic status (SES) area had the highest number of total outlets (n = 210) and the rural high SES area had the least (n = 19). Differences in the types of outlets across areas were observed. Comparing the Local Authority list to fieldwork across the geographical areas resulted in a range of PPV values obtained; with the highest in urban low SES areas (87%) and the lowest in Rural mixed SES (79%). While sensitivity ranged from 95% in the rural mixed SES area to 60% in the rural low SES area. There were no significant associations between field/desk percentage agreements across any of the divides. CONCLUSION: Despite the relatively small number of areas, this work furthers our understanding of the validity of using secondary data sources to identify and classify the foodscape in a variety of geographical settings. While classification of the foodscape using secondary Local Authority food outlet data with information obtained from the internet, is not without its difficulties, desk based classification would be an acceptable alternative to fieldwork, although it should be used with caution.

RESUMO

Aim: There are different methods to identify chronic kidney disease (CKD) in Clinical Practice Research Datalink (CPRD)-Hospital Episode Statistics (HES). Methods: Using CPRD-HES, nonvalvular atrial fibrillation patients were classified according to CKD category. Results: Using glomerular filtration rate/estimated glomerular filtration rate tests only to identify patients with CKD resulted in 3.5% stage 2, 2.7% stage 3, 0.3% stage 4 and 0.03% stage 5. Using data from diagnostic codes to identify patients with CKD resulted in 1.4% stage 3, 0.4% stage 4 and 0.3% stage 5. Using test records and codes resulted in 3.5% stage 2, 4.0% stage 3, 0.6% stage 4 and 0.4% stage 5. Conclusion: To identify CKD status in CPRD-HES, a combination of test records and codes should be used. Using diagnostic codes only significantly underestimates CKD prevalence.

RESUMO

BACKGROUND: There is limited evidence about the effectiveness of rehabilitation in meeting the longer-term needs of stroke patients and their carers. OBJECTIVE: To determine the clinical effectiveness and cost-effectiveness of an extended stroke rehabilitation service (EXTRAS). DESIGN: A pragmatic, observer-blind, parallel-group, multicentre randomised controlled trial with embedded health economic and process evaluations. Participants were randomised (1 : 1) to receive EXTRAS or usual care. SETTING: Nineteen NHS study centres. PARTICIPANTS: Patients with a new stroke who received early supported discharge and their informal carers. INTERVENTIONS: Five EXTRAS reviews provided by an early supported discharge team member between 1 and 18 months post early supported discharge, usually over the telephone. Reviewers assessed rehabilitation needs, with goal-setting and action-planning. Control treatment was usual care post early supported discharge. MAIN OUTCOME MEASURES: The primary outcome was performance in extended activities of daily living (Nottingham Extended Activities of Daily Living Scale) at 24 months post randomisation. Secondary outcomes at 12 and 24 months included patient mood (Hospital Anxiety and Depression Scale), health status (Oxford Handicap Scale), experience of services and adverse events. For carers, secondary outcomes included carers' strain (Caregiver Strain Index) and experience of services. Cost-effectiveness was estimated using resource utilisation costs (adaptation of the Client Service Receipt Inventory) and quality-adjusted life-years. RESULTS: A total of 573 patients (EXTRAS, n = 285; usual care, n = 288) with 194 carers (EXTRAS, n = 103; usual care, n = 91) were randomised. Mean 24-month Nottingham Extended Activities of Daily Living Scale scores were 40.0 (standard deviation 18.1) for EXTRAS (n = 219) and 37.2 (standard deviation 18.5) for usual care (n = 231), giving an adjusted mean difference of 1.8 (95% confidence interval -0.7 to 4.2). The mean intervention group Hospital Anxiety and Depression Scale scores were not significantly different at 12 and 24 months. The intervention did not improve patient health status or carer strain. EXTRAS patients and carers reported greater satisfaction with some aspects of care. The mean cost of resource utilisation was lower in the intervention group: -£311 (95% confidence interval -£3292 to £2787), with a 68% chance of EXTRAS being cost-saving. EXTRAS was associated with 0.07 (95% confidence interval 0.01 to 0.12) additional quality-adjusted life-years. At current conventional thresholds of willingness to pay for a quality-adjusted life-year, there is a 90% chance that EXTRAS is cost-effective. CONCLUSIONS: EXTRAS did not improve stroke survivors' performance in extended activities of daily living but did improve their overall satisfaction with services. Given the impact on costs and quality-adjusted life-years, there is a high chance that EXTRAS could be considered cost-effective. FUTURE WORK: Further research is required to identify whether or not community-based interventions can improve performance of extended activities of daily living, and to understand the improvements in health-related quality of life and costs seen by provision of intermittent longer-term specialist review. TRIAL REGISTRATION: Current Controlled Trials ISRCTN45203373. FUNDING: This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 24, No. 24. See the NIHR Journals Library website for further project information.


Early supported discharge enables stroke patients with mild or moderate disability to be discharged earlier than usual from hospital to continue rehabilitation at home. Randomised controlled trials have demonstrated that early supported discharge leads to increased independence for stroke survivors, and that early supported discharge is cost-effective. Early supported discharge is usually provided for up to 6 weeks and patients with ongoing physical, psychological or social needs are then referred to other services. In the UK, provision of longer-term rehabilitation is often limited. Lack of research evidence has meant that service development in this aspect of stroke care has lagged behind service development for acute care. This clinical trial evaluated an extended stroke rehabilitation service (EXTRAS) that started when early supported discharge ended. Stroke survivors and their carers were randomly assigned to receive EXTRAS or usual NHS care. EXTRAS involved five rehabilitation reviews conducted over 18 months by an early supported discharge team member, usually over the telephone. Each review consisted of an assessment of current needs, goal-setting and action-planning, and sought to improve patients' abilities and confidence to undertake extended activities of daily living (mobility, kitchen and domestic tasks, and leisure activities). There were no specific assessments or actions for carers but it was important to evaluate the impact that the new service had on carers. Patients and carers were followed up for 2 years and information was collected about their activities, mood, quality of life and services received. EXTRAS did not improve stroke survivors' performance in extended activities of daily living. However, patients who received EXTRAS reported less anxiety and less depression than those who received usual care, and patients and carers were more satisfied with some aspects of their care. EXTRAS did not improve carers' quality of life or stress. Health economic analyses suggest that EXTRAS improved patients' quality of life and may be good value for money. Further research is needed to identify other treatments to address the longer-term consequences of stroke.

RESUMO

BACKGROUND: Within the United Kingdom, the change from conventional to liquid based cytology (LBC) has brought with it the universal introduction of broom style samplers, as represented by the Cervex sampler. The aim of this study was to assess whether or not there were benefits associated with a change from wooden spatulae to broom style samplers for those countries where conversion to LBC might not be readily available or is not fully supported. METHODS: A longitudinal study was designed to compare the performance of Cervex brushes and extended-tip wooden spatulae as sampling devices for conventionally prepared cervical smears. General Practices serving the population of Hull and East Yorkshire (UK) were provided with Cervex brushes for a period of nine months to routinely collect cervical smears. The results of 66,931 cervical smear tests were compared between those practices that were using extended-tip wooden spatulae before the trial and then returned to their use afterwards, and those who were previously using Cervex samplers and continued to use them throughout. Analyses comparing both specimen inadequacy, as recorded on the standard cervical screening request form (HMR101), and also the presence of identified transformation zone (TZ) elements in smears, both indicated significant advantages associated with the Cervex brush. RESULTS: Inadequate smears decreased from 5.96% with extended-tip spatulae to 4.77% with Cervex brushes (p<0.001) and increased back to 7.34% when practices reverted to extended-tip spatulae after nine months. Under the same conditions, the proportion of smears containing identified TZ elements increased from 50.52% to 54.75% (p<0.001), before reverting to 45.47% (p<0.001). In contrast, for a control group of practices using the Cervex brush throughout, inadequate smears decreased in all phases of the study, with no significant variation in TZ sampling rates. CONCLUSIONS: Using the Cervex brush with conventional cytology significantly decreases inadequate smears and increases TZ sampling when compared to the extended-tip spatula and can offer improved cervical screening in countries unable or unwilling to convert to LBC.

RESUMO

There has been a dramatic change in the UK 'foodscape', accompanied by increasing rates of overweight and obesity. This study explores dietary change and change in BMI recorded longitudinally (1980-2000) against the change in food availability recorded retrospectively. Over 20 years the foodscape changed dramatically, with the total number of food outlets increasing by 79.4%. Analysis did not find a relationship between the foodscape and food intake patterns in 1980 or 2000. However statistically significant associations were found between 1980 foodscape and percent change in BMI. Adding geographical elements to a dietary study adds an interesting dimension in exploring the change in eating and BMI from adolescence to adulthood.

RESUMO

OBJECTIVES: To test the feasibility of recruitment, retention, outcome measures and internet delivery of dysarthria therapy for young people with cerebral palsy in a randomised controlled trial. DESIGN: Mixed methods. Single blind pilot randomised controlled trial, with control offered Skype therapy at end of study. Qualitative study of the acceptability of therapy delivery via Skype. SETTING: Nine speech and language therapy departments in northern England recruited participants to the study. Skype therapy was provided in a university setting. PARTICIPANTS: Twenty-two children (14 M, 8 F) with dysarthria and cerebral palsy (mean age 8.8 years (SD 3.2)) agreed to take part. Participants were randomised to dysarthria therapy via Skype (n=11) or treatment as usual (n=11). INTERVENTIONS: Children received either usual speech therapy from their local therapist for 6 weeks or dysarthria therapy via Skype from a research therapist. Usual therapy sessions varied in frequency, duration and content. Skype dysarthria therapy focused on breath control and phonation to produce clear speech at a steady rate, and comprised three 40 min sessions per week for 6 weeks. PRIMARY AND SECONDARY OUTCOME MEASURES: Feasibility and acceptability of the trial design, intervention and outcome measures. RESULTS: Departments recruited two to three participants. All participants agreed to random allocation. None withdrew from the study. Recordings of children's speech were made at all time points and rated by listeners. Families allocated to Skype dysarthria therapy judged internet delivery of the therapy to be acceptable. All families reported that the study design was acceptable. Treatment integrity checks suggested that the phrases practised in one therapy exercise should be reduced in length. CONCLUSIONS: A delayed treatment design, in which dysarthria therapy is offered at the end of the study to families allocated to treatment as usual, is acceptable. A randomised controlled trial of internet delivered dysarthria therapy is feasible.

RESUMO

Background: Vitamin D insufficiency is common in older people and may lead to increased bone resorption, bone loss, and increased falls and fractures. However, clinical trials assessing the effect of vitamin D supplementation on bone mineral density (BMD) have yielded conflicting results. Objectives: This study examined the effect of vitamin D supplementation on BMD at the hip, using dual-energy X-ray absorptiometry. Methods: A total of 379 adults aged ≥70 y (48% women; mean age: 75 y) from the northeast of England were randomly allocated to 1 of 3 doses of vitamin D3 [12,000 international units (IU), 24,000 IU, or 48,000 IU] given once a month. The primary outcome was change in BMD (ΔBMD) at the hip. Secondary endpoints comprised the dose effects on femoral neck BMD, falls, circulating calciotropic hormones, bone turnover markers, and adverse events. Results: The mean ± SD baseline plasma 25-hydroxyvitamin D [25(OH)D] concentration was 40.0 ± 20.1 nmol/L, which increased after 12 mo to a mean 25(OH)D of 55.9, 64.6, or 79.0 nmol/L for participants receiving a monthly dose of 12,000, 24,000, or 48,000 IU, respectively (P < 0.01 for difference). There was no between-group difference in ΔBMD. However, parathyroid hormone concentrations decreased in all 3 groups, with a significantly greater decrease in the 48,000-IU group compared with the 12,000-IU group (P < 0.01). There were no differences in any adverse events between groups, with 3 cases of hypercalcemia, none of nephrolithiasis, and 249 falls observed. Conclusions: There was no difference in change in BMD over 12 mo between the 3 doses of vitamin D, suggesting no effect of the intervention or a similar attenuation of the anticipated decrease in BMD over 12 mo. The treatment was safe and effective in increasing plasma 25(OH)D concentrations, with no dose-related adverse events. This trial was registered at the EU Clinical Trials Register (EudraCT 2011-004890-10) and the ISRCTN Registry (ISRCTN35648481).

Aim: To describe the renal function of individuals newly diagnosed with non-valvular atrial fibrillation in England, and describe how oral anticoagulant (OAC) treatment varies according to renal function. Patients & methods: We identified a cohort of individuals with non-valvular atrial fibrillation (n = 18,419) and described their renal function at diagnosis and the prevalence of OAC treatment initiation by renal function. Results: 79% of individuals had some evidence of renal dysfunction with 12% having a glomerular filtration rate <30 ml/min/1.73 m2. OAC treatment initiation in the 6 months following diagnosis was lower in individuals with severe renal dysfunction than in those with normal renal function. Conclusion: The high prevalence of renal dysfunction and low OAC treatment prevalence highlights the need for additional evidence regarding OACs in individuals with severe renal dysfunction.

RESUMO

Spontaneous preterm birth (sPTB, delivery <37 weeks gestation), accounts for approximately 10% of births worldwide; the aetiology is multifactorial with intra-amniotic infection being one contributing factor. This study aimed to determine whether asymptomatic women with a history of sPTB or cervical surgery have altered levels of inflammatory/antimicrobial mediators and/or microflora within cervical fluid at 22-24 weeks gestation. External cervical fluid was collected from women with history of previous sPTB and/or cervical surgery at 22-24 weeks gestation (n = 135). Cytokine and antimicrobial peptides were measured on a multiplex platform or by ELISA. qPCR was performed for detection of 7 potentially pathogenic bacterial species. IL-8 and IL-1ß levels were lower in women who delivered preterm compared to those who delivered at term (IL-8 P = 0.02; IL-1ß P = 0.04). There were no differences in elafin or human beta defensin-1 protein levels between the two groups. Multiple bacterial species were detected in a higher proportion of women who delivered preterm than in those who delivered at term (P = 0.005). Cervical fluid IL-8 and IL-1ß and microflora have the potential to be used as biomarkers to predict sPTB in high risk women.

RESUMO

BACKGROUND: Research estimates that 30% of children under the age of 16 years in the UK live with at least one parent with an alcohol use disorder (AUD). Parental AUDs are associated with adverse childhood experiences and poorer outcomes for children. The PAReNTS (Promoting Alcohol Reduction in Non-Treatment Seeking parents) trial aims to examine the feasibility and acceptability of a randomised controlled trial of brief alcohol interventions to reduce parental alcohol misuse. METHODS: The cluster randomised controlled trial will be conducted within early help family support and children's social care services in three local authorities in the North East of England: Newcastle, Durham and North Tyneside. All eligible parents the caseloads of participating practitioners will be screened for an AUD using the Alcohol Use Disorder Identification Test - Consumption (AUDIT-C) screening tool by the social care practitioners within routine appointments. All parents who score 5 or more on the AUDIT-C will be invited to participate in the trial. Consenting participants will complete a baseline questionnaire before receiving one of three randomised interventions: (i) healthy lifestyle leaflet (control intervention); (ii) a brief alcohol advice intervention delivered by the social care practitioner plus healthy lifestyle leaflet; (iii) a brief alcohol advice intervention delivered by the social care practitioner, healthy lifestyle leaflet plus a 40-min behaviour change intervention with an optional review session delivered by the local alcohol service. Follow-up data will be collected 6 and 12 months post recruitment. A linked qualitative study will explore participating parent and practitioner views on the acceptability of trial processes and interventions. DISCUSSION: The PAReNTS trial will provide a robust estimate of recruitment, retention and consent rates in order to inform the design of a future definitive study examining the effectiveness and cost-effectiveness of alcohol screening and brief interventions to reduce parental AUDs within vulnerable families. TRIAL REGISTRATION: ISRCTN registry ISRCTN60291091; protocol version 2; 17.10.2016.

RESUMO

BACKGROUND: Evidence suggests that increased preoperative alcohol consumption increases the risk of postoperative complications; therefore, a reduction or cessation in alcohol intake before surgery may reduce perioperative risk. Preoperative assessment presents an opportunity to intervene to optimise patients for surgery. This multicentre, two-arm, parallel group, individually randomised controlled trial will investigate whether a definitive trial of a brief behavioural intervention aimed at reducing preoperative alcohol consumption is feasible and acceptable to healthcare professionals responsible for its delivery and the preoperative elective orthopaedic patient population. METHODS: Screening will be conducted by trained healthcare professionals at three hospitals in the North East of England. Eligible patients (those aged 18 or over, listed for elective hip or knee arthroplasty surgery and scoring 5 or more or reporting consumption of six or more units on a single occasion at least weekly on the alcohol screening tool) who enrol in the trial will be randomised on a one-to-one non-blinded basis to either treatment as usual or brief behavioural intervention delivered in the pre-assessment clinic. Patients will be followed up 1-2 days pre-surgery, 1-5 days post-surgery (as an in-patient), 6 weeks post-surgery, and 6 months post intervention. Feasibility will be assessed through rates of screening, eligibility, recruitment, and retention to 6-month follow-up. An embedded qualitative study will explore the acceptability of study methods to patients and staff. DISCUSSION: This pilot randomised controlled trial will establish the feasibility and acceptability of trial procedures reducing uncertainties ahead of a definitive randomised controlled trial to establish the effectiveness of brief behavioural intervention to reduce alcohol consumption in the preoperative period and the potential impact on perioperative complications. TRIAL REGISTRATION: Reference number ISRCTN36257982.

RESUMO

Importance: There are no medical interventions for the orphan disease CYLD cutaneous syndrome (CCS). Transcriptomic profiling of CCS skin tumors previously highlighted tropomyosin receptor kinases (TRKs) as candidate therapeutic targets. Objective: To investigate if topical targeting of TRK with an existing topical TRK inhibitor, pegcantratinib, 0.5% (wt/wt), is safe and efficacious in CCS. Design, Setting, and Participants: A phase 1b open-label safety study, followed by a phase 2a within-patient randomized (by tumor), double-blind, placebo-controlled trial (the Tropomyosin Receptor Antagonism in Cylindromatosis [TRAC] trial). The setting was a single-center trial based at a tertiary dermatogenetics referral center for CCS (Royal Victoria Infirmary, Newcastle, United Kingdom). Patients who had germline mutations in CYLD or who satisfied clinical diagnostic criteria for CCS were recruited between March 1, 2015, and July 1, 2016. Interventions: In phase 1b, patients with CCS applied pegcantratinib for 4 weeks to a single skin tumor. In phase 2a, allocation of tumors was to either receive active treatment on the right side and placebo on the left side (arm A) or active treatment on the left side and placebo on the right side (arm B). Patients were eligible if they had 10 small skin tumors, with 5 matched lesions on each body side; patients were randomized to receive active treatment (pegcantratinib) to one body side and placebo to the other side once daily for 12 weeks. Main Outcomes and Measures: The primary outcome measure was the number of tumors meeting the criteria for response in a prespecified critical number of pegcantratinib-treated tumors. Secondary clinical outcome measures included an assessment for safety of application, pain in early tumors, and compliance with the trial protocol. Results: In phase 1b, 8 female patients with a median age of 60 years (age range, 41-80 years) were recruited and completed the study. None of the participants experienced any adverse treatment site reactions. Three patients reported reduced pain in treated tumors. In phase 2a (15 patients [13 female; median age, 51 years], with 150 tumors), 2 tumors treated with pegcantratinib achieved the primary outcome measure of response compared with 6 tumors treated with placebo. The primary prespecified number of responses was not met. The incidence of adverse events was low. Conclusions and Relevance: In this study, pegcantratinib, 0.5% (wt/wt), applied once daily appeared to be well tolerated and to penetrate the tumor tissue; however, the low tumor drug concentrations demonstrated are likely to account for the lack of response. Dose-escalation studies to assess the maximal tolerated dose may be beneficial in future studies of CCS. Trial Registration: isrctn.org Identifier: ISRCTN75715723.

RESUMO

Traditional dietary assessment methods, used in the UK, such as weighed food diaries impose a large participant burden, often resulting in difficulty recruiting representative samples and underreporting of energy intakes. One approach to reducing the burden placed on the participant is to use portion size assessment tools to obtain an estimate of the amount of food consumed, removing the need to weigh all foods. An age range specific food atlas was developed for use in assessing children's dietary intakes. The foods selected and portion sizes depicted were derived from intakes recorded during the UK National Diet and Nutrition Surveys of children aged 1.5 to 16 years. Estimates of food portion sizes using the food atlas were compared against 4-day weighed intakes along with in-school / nursery observations, by the research team. Interviews were conducted with parents the day after completion of the diary, and for children aged 4 to 16 years, also with the child. Mean estimates of portion size consumed were within 7% of the weight of food recorded in the weighed food diary. The limits of agreement were wide indicating high variability of estimates at the individual level but the precision increased with increasing age. For children 11 years and over, agreement with weighed food diaries, was as good as that of their parents in terms of total weight of food consumed and of intake of energy and key nutrients. The age appropriate food photographs offer an alternative to weighed intakes for dietary assessment with children.

RESUMO

BACKGROUND: Patients with germline mutations in a tumour suppressor gene called CYLD develop multiple, disfiguring, hair follicle tumours on the head and neck. The prognosis is poor, with up to one in four mutation carriers requiring complete surgical removal of the scalp. There are no effective medical alternatives to treat this condition. Whole genome molecular profiling experiments led to the discovery of an attractive molecular target in these skin tumour cells, named tropomyosin receptor kinase (TRK), upon which these cells demonstrate an oncogenic dependency in preclinical studies. Recently, the development of an ointment containing a TRK inhibitor (pegcantratinib - previously CT327 - from Creabilis SA) allowed for the assessment of TRK inhibition in tumours from patients with inherited CYLD mutations. METHODS/DESIGN: Tropomysin Receptor Antagonism in Cylindromatosis (TRAC) is a two-part, exploratory, early phase, single-centre trial. Cohort 1 is a phase 1b open-labelled trial, and cohort 2 is a phase 2a randomised double-blinded exploratory placebo-controlled trial. Cohort 1 will determine the safety and acceptability of applying pegcantratinib for 4 weeks to a single tumour on a CYLD mutation carrier that is scheduled for a routine lesion excision (n = 8 patients). Cohort 2 will investigate if CYLD defective tumours respond following 12 weeks of treatment with pegcantratinib. As patients have multiple tumours, we intend to treat 10 tumours in each patient, 5 with active treatment and 5 with placebo. Patients will be allocated both active and placebo treatments to be applied randomly to tumours on the left or right side. The target is to treat 150 tumours in a maximum of 20 patients. Tumour volume will be measured at baseline and at 4 and 12 weeks. The primary outcome measure is the proportion of tumours responding to treatment by 12 weeks, based on change in tumour volume, with secondary measures based on adverse event profile, treatment compliance and acceptability, changes in tumour volume and surface area, patient quality of life and pain. DISCUSSION: Interventions for rare genetic skin diseases are often difficult to assess in an unbiased way due to small patient numbers and the challenges of incorporating adequate controls into trial design. Here we present a single-centre, randomised, placebo-controlled trial design that leverages the multiplicity of tumours seen in an inherited skin tumour syndrome that may inform the design of other studies in similar genetic diseases.
