Background and aims: Offering financial incentives is effective for smoking cessation during pregnancy. We tested the effectiveness of financial incentives for maintaining postpartum cessation, comparing 12-month and 3-month incentives with each other and with usual care (UC). Design, setting and participants: This study was a pragmatic, multi-centre, three-arm randomized controlled trial involving four English, National Health Service, stop smoking services. A total of 462 postpartum women (aged ≥ 16 years) took part, who stopped smoking during pregnancy with financial incentives, validated as abstinent from smoking at end of pregnancy or early postpartum. Interventions: Interventions comprised (i) UC; (ii) UC plus up to £60 of financial voucher incentives offered to participants and £60 offered to an optional significant-other supporter, over 3 months postpartum, contingent upon validated abstinence ('3-month incentives'); or (iii) UC plus '3-month incentives' plus £180 of vouchers offered to participants over 9 months postpartum, contingent upon abstinence ('12-month incentives'). Measurements: Primary outcome: biochemically validated abstinence at 1 year postpartum. To adjust for testing all comparisons between groups with equal precision, P < 0.017 was necessary for significance. Secondary outcomes: self-reported and validated abstinence at 3 months postpartum; self-reported abstinence at 1 year postpartum. Findings: Primary outcome ascertainment: abstinence was 39.6% (63/159) 12 months incentives, 21.4% (33/154) 3 months incentives and 28.2% (42/149) UC. Adjusted odds ratios [95% confidence interval (CI)] = 12-month versus 3-month incentives OR = 2.41 (95% CI = 1.46-3.96), P = 0.001; 12 months versus UC 1.67 (1.04-2.70), P = 0.035; 3 months versus UC 0.69 (0.41-1.17), P = 0.174. Bayes factors indicated that for 12- month versus 3-month incentives and 12 months versus UC there was good evidence for the alternative hypothesis, and for 3 months versus UC there was good evidence for the null hypothesis. Conclusions: This randomized controlled trial provides weak evidence that up to £300 of voucher incentives over 12 months is effective for maintaining smoking abstinence postpartum compared with usual care. There was good evidence that 12-month incentives are superior to those over only 3 months, for which there was no evidence of effectiveness relative to usual care. [ABSTRACT FROM AUTHOR]

Objective: To test the feasibility of a telephone delivered intervention, informed by cognitive behavioural principles, for post-stroke fatigue, and estimated its effect on fatigue and other outcomes. Design: Randomised controlled parallel group trial. Setting: Three Scottish stroke services. Subjects: Stroke survivors with fatigue three months to two years post-stroke onset. Interventions: Seven telephone calls (fortnightly then a 'booster session' at 16 weeks) of a manualised intervention, plus information about fatigue, versus information only. Main measures: Feasibility of trial methods, and collected outcome measures (fatigue, mood, anxiety, social participation, quality of life, return to work) just before randomisation, at the end of treatment (four months after randomisation) and at six months after randomisation. Results: Between October 2018 and January 2020, we invited 886 stroke survivors to participate in postal screening: 188/886 (21%) returned questionnaires and consented, of whom 76/188 (40%) were eligible and returned baseline forms; 64/76 (84%) returned six month follow-up questionnaires. Of the 39 allocated the intervention, 23 (59%) attended at least four sessions. At six months, there were no significant differences between the groups (adjusted mean differences in Fatigue Assessment Scale −0.619 (95% CI −4.9631, 3.694; p = 0.768), the Generalised Anxiety Disorder 7 −0.178 (95% CI −3.823, 3.467, p = 0.92), and the Patient Health Questionnaire −0.247 (95% CI −2.935, 2.442, p = 0.851). There were no between-group differences in quality of life, social participation or return to work. Conclusion: Patients can be recruited to a trial of this design. These data will inform the design of further trials in post-stroke fatigue. [ABSTRACT FROM AUTHOR]

Background: Advance Care Planning is recommended for people with end-stage kidney disease but evidence is limited. Robust clinical trials are needed to investigate the impact of advance care planning in this population. There is little available data on cost-effectiveness to guide decision makers in allocating resources for advance care planning. Therefore we sought to determine the feasibility of a randomised controlled trial and to test methods for assessing cost-effectiveness.Methods: A deferred entry, randomised controlled feasibility trial, incorporating economic and process evaluations, with people with end-stage kidney disease, aged 65 years or older, receiving haemodialysis, in two renal haemodialysis units in Northern Ireland, UK. A nurse facilitator helped the patient make an advance care plan identifying: a surrogate decision-maker; what the participant would like to happen in the future; any advance decision to refuse treatment; preferred place of care at end-of-life.Results: Recruitment lasted 189 days; intervention and data collection 443 days. Of the 67 patients invited to participate 30 (45%) declined and 36 were randomised to immediate or deferred advance care plan groups. Twenty-two (61%) made an advance care plan and completed data collection at 12 weeks; 17 (47.2%) were able to identify a surrogate willing to be named in the advance care plan document. The intervention was well-received and encouraged end-of-life conversations, but did not succeed in helping patients to fully clarify their values or consider specific treatment choices. There was no significant difference in health system costs between the immediate and deferred groups.Conclusions: A trial of advance care planning with participants receiving haemodialysis is feasible and acceptable to patients, but challenging. A full trial would require a pool of potential participants five times larger than the number required to complete data collection at 3 months. Widening eligibility criteria to include younger (under 65 years of age) and less frail patients, together with special efforts to engage and retain surrogates may improve recruitment and retention. Traditional advance care planning outcomes may need to be supplemented with those that are defined by patients, helping them to participate with clinicians in making medical decisions.Trial Registration: Registered December 16, 2015.

The study evaluated the implementation fidelity and effectiveness of KiVa, an evidence-based program that aims to prevent and address bullying in schools, with a particular emphasis on changing the role of bystanders. The study was a two-arm waitlist control cluster randomized controlled trial in which 22 primary schools (clusters) (N = 3214 students aged 7-11) were allocated using a 1:1 ratio to intervention (KiVa; 11 clusters, n = 1588 students) and a waitlist control (usual school provision; 11 clusters, n = 1892 children)). The trial statistician (but not schools or researchers) remained blind to allocation status. The outcomes were as follows: student-reported victimization (primary outcome) and bullying perpetration; teacher-reported child behavior and emotional well-being; and school absenteeism (administrative records). Implementation fidelity was measured using teacher-completed online records (for class lessons) and independent researcher observations (for school-wide elements). Outcome analyses involved 11 intervention schools (n = 1578 children) and 10 control schools (n = 1636 children). There was no statistically significant effect on the primary outcome of child-reported victimization (adjusted intervention/control OR 0.76; 95% CI 0.55 to 1.06; p = 0.11) or on the secondary outcomes. The impact on victimization was not moderated by child gender, age, or victimization status at baseline. Lesson adherence was good but exposure (lesson length) was lower than the recommended amount, and there was considerable variability in the implementation of whole school elements. The trial found insufficient evidence to conclude that KiVa had an effect on the primary outcome. A larger trial of KiVa in the UK is warranted, however, with attention to issues regarding implementation fidelity. Trial registration: Current Controlled Trials ISRCTN23999021 Date 10-6-13.

Objectives: This research investigates the healing practices of modern Paganism using a randomized controlled trial. Paganism is a burgeoning belief system in the United Kingdom, within which healing is a key aspect. However, Pagan spell-casting practices have received little attention from distance healing researchers. This study aims to address this gap in the literature. Design: This study utilized a randomized, double-blind, delayed intervention design. Settings/Location: Research took place at the University of Northampton. Subjects: Forty-four participants (30 females, 14 males) were recruited using snowball sampling (mean age = 24.30; range = 18–55). Procedure: Participants were randomly allocated to either Group A or B. Participants made written requests to the practitioner about changes they would like to see in their lives and provided a photograph and personal item to be used during the intervention. Participants attended meetings once a week during which they would take part in a guided body scan meditation before completing a quality-of-life measure. Healing practices were conducted for Group A between weeks 1 and 2 and for Group B between weeks 2 and 3. Outcome Measure: Well-being was measured using the 26-item WHOQOL-BREF. Results: Multivariate analysis of variance (MANOVA) showed a significant, positive change in general health from weeks 1 to 4 (F = 4.02, p = 0.025, η2 = 0.149). Separate analysis of variances of the four WHOQOL domains showed significant improvements across the study in the physical and psychologic domains only; there was no significant group difference on any of the outcomes. Conclusion: All participants showed an increase in health and well-being domains directly related to their spell requests. However, there are no group differences to suggest that the spell-casting intervention was responsible. [ABSTRACT FROM AUTHOR]

Objective: To assess the costs, effects, and cost-utility of an accelerated physiotherapy programme versus a standard physiotherapy programme following resurfacing hip arthroplasty. Design: A cost-utility analysis alongside a randomized controlled trial. Setting: A UK National Health Service hospital and patients' homes. Subjects: A total of 80 male resurfacing hip arthroplasty patients randomized post procedure to one of the two programmes. Interventions: The accelerated physiotherapy programme commenced in hospital with patients being fully weight bearing, without hip precautions, and following a range of exercises facilitating gait re-education, balance, and lower limb strength. Standard physiotherapy commenced in hospital, but hip precautions were used and exercises were only partially weight bearing. In both groups, patients continued with their exercises at home for an eight-week period. Main measures: Data on healthcare contacts were collected from patients to 12 months and costed using unit costs from national sources. Information was also collected on patients' costs. Health-related quality of life was measured using the EuroQol EQ-5D questionnaire and used to estimate quality-adjusted life years (QALYs) to 12 months. Mean costs and QALYs for each trial arm were compared. Results: On average, the accelerated physiotherapy programme was less expensive (mean cost difference −£200; 95% confidence interval: −£656 to £255) and more effective (mean QALY difference 0.13; 95% confidence interval: 0.05 to 0.21) than standard physiotherapy and had a high probability of being cost-effective. Conclusion: From the National Health Service perspective, an accelerated physiotherapy programme for male patients undergoing revision of total hip arthroplasty (RHA) is very likely to be cost-effective when compared to a standard physiotherapy programme.

Objective: To evaluate the feasibility of a multicentre randomized controlled trial of ReaDySpeech, an online speech therapy programme for people with dysarthria. Design: Feasibility randomized controlled trial, 2:1 minimization procedure. Setting: Four UK NHS services across hospital and community. Participants: Forty participants with dysarthria at least one week post-stroke. Interventions/comparator: ReaDySpeech with usual care (n = 26) versus usual care only (n = 14). Main outcomes: Feasibility measures included the following: recruitment and retention rate, time taken to carry out assessments, success of outcome assessor blinding, fidelity and adherence. Participant baseline and outcome measures collected before and after 8-10 weeks of intervention were the Frenchay Dysarthria Assessment II, Therapy Outcome Measure, Communication Outcomes After Stroke Scale, EQ-5D-5L and Dysarthria Impact Profile. Results: Recruited 40 participants out of 74 eligible people, 1-13 weeks post stroke and mean age 69 years (37-99). Retention was very high (92%). Assessor blinding was not achieved with intervention allocation correctly guessed for 70% of participants (26/37). Time to carry out assessments was acceptable to participants. ReaDySpeech was delivered to 16 of 26 allocated participants, who completed 55% of prescribed activities, but both interventions were delivered at low intensity (mean 6.6 face-to-face sessions of 40-minute duration). Conclusion: Recruitment and retention in this randomized controlled trial of computerized therapy for dysarthria is feasible for acute stroke. However, further feasibility work is needed to evaluate whether it is possible to recruit chronic stroke; increase intervention delivery, intensity and adherence; achieve outcome assessor blinding by video-recording and to determine sample size for a larger trial of effectiveness.

Objective: To determine the feasibility of conducting a trial of a pre-surgical psychological intervention on pain, function, and mood in people with knee osteoarthritis listed for total knee arthroplasty. Design: Multi-centre, mixed-methods feasibility randomized controlled trial of intervention plus usual care versus usual care. Setting: Participants’ homes or hospital. Participants: Patients with knee osteoarthritis listed for total knee arthroplasty and score >7 on either subscales of Hospital Anxiety and Depression Scale. Intervention: Up-to 10 sessions of psychological intervention (based on cognitive behavioural therapy). Main measures: Feasibility outcomes (recruitment and retention rates, acceptability of trial procedures and intervention, completion of outcome measures), and standardized questionnaires assessing pain, function, and mood at baseline, and four and six months post-randomisation. Results: Of 222 people screened, 81 did not meet inclusion criteria, 64 did not wish to participate, 26 were excluded for other reasons, and 51 were randomized. A total of 30 completed 4-month outcomes and 25 completed 6-month outcomes. Modal number of intervention sessions completed was three (range 2–8). At 6-month follow-up, mood, pain, and physical function scores were consistent with clinically important benefits from intervention, with effect sizes ranging from small (d = 0.005) to moderate (d = 0.74), and significant differences in physical function between intervention and usual care groups (d = 1.16). Feedback interviews suggested that participants understood the rationale for the study, found the information provided adequate, the measures comprehensive, and the intervention acceptable. Conclusion: A definitive trial is feasible, with a total sample size of 444 people. Pain is a suitable primary outcome, but best assessed 6 and 12 months post-surgery. [ABSTRACT FROM AUTHOR]

Abstract: Background: Dysphagia is common after stroke, affecting up to 50% of patients initially. It can lead to post‐stroke pneumonia, which causes 30% of stroke‐related deaths, a longer hospital stay and poorer health outcomes. Dysphagia care post‐stroke generally focuses on the management of symptoms, via modified oral intake textures and adapted posture, rather than direct physical rehabilitation of the swallowing function. Transcutaneous neuromuscular electrical stimulation (NMES) is a promising rehabilitation technology that can be used to stimulate swallowing; however, findings regarding efficacy have been conflicting. Aims: This pilot randomized controlled study involving three UK sites compared the efficacy of the Ampcare Effective Swallowing Protocol (ESP), combining NMES with swallow‐strengthening exercises, with usual care in order to clarify evidence on NMES in the treatment of dysphagia post‐stroke. A further objective was to pilot recruitment procedures and outcome measures in order to inform the design of a full‐scale trial. Methods & Procedures: Thirty patients were recruited and randomized into either (1) usual speech and language therapy dysphagia care; or (2) Ampcare ESP, receiving treatment 5 days/week for 4 weeks. Outcome measures included: the Functional Oral Intake Scale (FOIS), the Rosenbek Penetration‐Aspiration Scale (PAS) and patient‐reported outcomes (Swallow Related Quality of Life—SWAL‐QOL). Outcomes & Results: Thirty patients were recruited; 15 were randomized to the Ampcare ESP intervention arm and 15 to usual care. A greater proportion (75%, or 9/12) of patients receiving Ampcare ESP improved compared with 57% (or 8/14) of the usual‐care group. Patients receiving Ampcare ESP also made clinically meaningful change (a comparative benefit of 1.5 on the FOIS, and on the PAS: 1.35 for diet and 0.3 for fluids) compared with usual care. The intervention group also reported much better outcome satisfaction. Conclusions & Implications: The pilot demonstrated successful recruitment, treatment safety and tolerability and clinically meaningful outcome improvements, justifying progression to a fully powered study. It also showed clinically meaningful treatment trends for the Ampcare ESP intervention. [ABSTRACT FROM AUTHOR]

Objectives To design and evaluate the effectiveness of a pre-notification leaflet about research to increase recruitment to a randomized controlled trial (RCT). Methods A methodological, two-arm, RCT was conducted, embedded within an existing cohort RCT (REFORM). Participants were randomized for the embedded trial, using a 1:2 ratio (intervention : control) before being randomized for REFORM. Controls received a trial recruitment pack. The intervention group received an additional pre-notification leaflet 2-3 weeks before the recruitment pack. Primary and secondary analyses were conducted using relative risk, the Cox proportional hazards model and incremental cost-effectiveness ratios. Results Of the 1436 intervention group participants, 73 (5.1%) were randomized into the REFORM trial compared with 126 (4.4%) of the 2878 control group participants. The associated relative risk (1.16) was not statistically significant [95% confidence interval (CI) 0.88-1.56]. Return rate was not significantly increased (relative risk 1.10, 95% CI 0.92-1.28) nor time to return decreased (hazard ratio: 1.11, 95% CI 0.93-1.33). Incremental cost-effectiveness ratios indicated the intervention may be cost-effective if the true estimate of effect was close to the upper bound of the associated 95% CI. Conclusion Pre-notification for potential trial participants demonstrated a small difference to randomization (0.7% difference) and return rates (1.1% difference) in favour of the intervention. Results should however be interpreted with caution as CIs for these estimates cross the point of no effect. Nevertheless, this research enhances existing evidence for pre-notification to increase recruitment rates, with further development and assessment of this potentially cost-effective intervention being recommended.

Objective: The Trial of Wii™ in Stroke investigated the efficacy of using the Nintendo Wii Sports™ (Wii™) to improve affected arm function after stroke. Design: Multicentre, pragmatic, parallel group, randomized controlled trial. Setting: Home-based rehabilitation. Subjects: A total of 240 participants aged 24-90 years with arm weakness following a stroke within the previous six months. Intervention: Participants were randomly assigned to exercise daily for six weeks using the Wii™ or arm exercises at home. Main measures: Primary outcome was change in the affected arm function at six weeks follow-up using the Action Research Arm Test. Secondary outcomes included occupational performance, quality of life, arm function at six months and a cost effectiveness analysis. Results: The study was completed by 209 participants (87.1%). There was no significant difference in the primary outcome of affected arm function at six weeks follow-up (mean difference -1.7, 95% CI -3.9 to 0.5, p = 0.12) and no significant difference in secondary outcomes, including occupational performance, quality of life or arm function at six months, between the two groups. No serious adverse events related to the study treatment were reported. The cost effectiveness analysis showed that the Wii™ was more expensive than arm exercises £1106 (SD 1656) vs. £730 (SD 829) (probability 0.866). Conclusion: The trial showed that the Wii™ was not superior to arm exercises in home-based rehabilitation for stroke survivors with arm weakness. The Wii™ was well tolerated but more expensive than arm exercises. [ABSTRACT FROM AUTHOR]

Objective: To explore the feasibility of implementing and evaluating the Guide to Action Care Home fall prevention intervention. Design: Two-centre, cluster feasibility randomized controlled trial and process evaluation. Setting: Purposive sample of six diverse old age/learning disability, long stay care homes in Nottinghamshire, UK. Subjects: Residents aged over 50 years, who had fallen at least once in the past year, not bed-bound, hoist-dependent or terminally ill. Interventions: Intervention homes (n = 3) received Guide to Action Care Home fall prevention intervention training and support. Control homes (n = 3) received usual care. Outcomes: Recruitment, attrition, baseline and six-month outcome completion, contamination and intervention fidelity, compliance, tolerability, acceptance and impact. Results: A total of 81 of 145 (56%) care homes expressed participatory interest. Six of 22 letter respondent homes (27%) participated. The expected resident recruitment target was achieved by 76% (52/68). Ten (19%) residents did not complete follow-up (seven died, three moved). In intervention homes 36/114 (32%) staff attended training. Two of three (75%) care homes received protocol compliant training. Staff valued the training, but advised greater management involvement to improve intervention implementation. Fall risks were assessed, actioned and recorded in care records. Of 115 recorded falls, 533/570 (93%) of details were complete. Six-month resident fall rates were 1.9 and 4.0 per year for intervention and control homes, respectively. Conclusions: The Guide to Action Care Home is implementable under trial conditions. Recruitment and follow-up rates indicate that a definitive trial can be completed. Falls (primary outcome) can be ascertained reliably from care records. [ABSTRACT FROM AUTHOR]

Objectives Apathy is common, impactful, and difficult to manage in people with dementia. We evaluated the efficacy of nonpharmacological interventions, exercise, and social interaction, in combination with antipsychotic review, to reduce apathy in people with dementia living in nursing homes in a cluster randomized controlled trial (RCT). Methods Well-being and health for people with dementia (WHELD) program included a 2 × 2 × 2 factorial cluster RCT involving people with dementia living in 16 nursing homes in the United Kingdom. All homes received training in person-centered care, and were randomized to receive antipsychotic review, social interaction, and exercise, either alone or in combinations. Apathy was one of the secondary outcomes of the WHELD trial, and it was measured by the Neuropsychiatric Inventory–nursing home version at baseline and 9 months (n = 273). We used multilevel mixed effects linear regression models to assess the impact of the interventions on apathy. Results Prevalence of apathy was 44.0% (n = 120; 95% confidence interval [CI] 38.1%–49.9%) at baseline. Severity of apathy had significant positive correlations with dementia severity, neuropsychiatric symptoms, depressive symptoms, agitation, and the needs of the people with dementia ( P < .001). Antipsychotic review reduced antipsychotic use, but it significantly increased apathy (β = 5.37; SE = 0.91; P < . 001). However, antipsychotic review in combination with either social interaction (β = −5.84; SE = 1.15; P < . 001) or exercise (β = −7.54; SE = 0.93; P < . 001) significantly reduced apathy. Conclusions Antipsychotic review can play a significant role in improving apathy in people with dementia living in nursing homes, when combined with psychosocial interventions such as social interaction and exercise. Guidance must be adapted to reflect this subtlety in care. [ABSTRACT FROM AUTHOR]

Background: Parenteral nutrition is central to the care of very immature infants. Current international recommendations favor higher amino acid intakes and fish oil-containing lipid emulsions. Objective: The aim of this trial was to compare 1) the effects of high [immediate recommended daily intake (Imm-RDI)] and low [incremental introduction of amino acids (Inc-AAs)] parenteral amino acid delivery within 24 h of birth on body composition and 2) the effect of a multicomponent lipid emulsion containing 30% soybean oil, 30% medium-chain triglycerides, 25% olive oil, and 15% fish oil (SMOF) with that of soybean oil (SO)-based lipid emulsion on intrahepatocellular lipid (IHCL) content. Design: We conducted a 2-by-2 factorial, double-blind, multicenter randomized controlled trial. Results: We randomly assigned 168 infants born at,31 wk of gestation. We evaluated outcomes at term in 133 infants. There were no significant differences between Imm-RDI and Inc-AA groups for non-adipose mass [adjusted mean difference: 1.0 g (95% CI: -108, 111 g; P = 0.98)] or between SMOF and SO groups for IHCL [adjusted mean SMOF:SO ratio: 1.1 (95% CI: 0.8, 1.6; P = 0.58]. SMOF does not affect IHCL content. There was a significant interaction (P = 0.05) between the 2 interventions for nonadipose mass. There were no significant interactions between group differences for either primary outcome measure after adjusting for additional confounders. Imm-RDI infants were more likely than Inc-AA infants to have blood urea nitrogen concentrations >7 mmol/L or >10 mmol/L, respectively (75% compared with 49%, P < 0.01; 49% compared with 18%, P < 0.01). Head circumference at term was smaller in the Imm-RDI group [mean difference: 20.8 cm (95% CI: 21.5, -0.1 cm; P = 0.02)]. There were no significant differences in any prespecified secondary outcomes, including adiposity, liver function tests, incidence of conjugated hyperbilirubinemia, weight, length, mortality, and brain volumes. Conclusion: Imm-RDI of parenteral amino acids does not benefit body composition or growth to term and may be harmful.

Background. Repeated epidemiological surveys show no decline in depression although uptake of treatments has grown. Universal depression prevention interventions are effective in schools but untested rigorously in adulthood. Selective prevention programmes have poor uptake. Universal interventions may be more acceptable during routine healthcare contacts for example antenatally. One study within routine postnatal healthcare suggested risk of postnatal depression could be reduced in non-depressed women from 11% to 8% by giving health visitors psychological intervention training. Feasibility and effectiveness in other settings, most notably antenatally, is unknown. Method. We conducted an external pilot study using a cluster trial design consisting of recruitment and enhanced psychological training of randomly selected clusters of community midwives (CMWs), recruitment of pregnant women of all levels of risk of depression, collection of baseline and outcome data prior to childbirth, allowing time for women 'at increased risk' to complete CMW-provided psychological support sessions. Results. Seventy-nine percent of eligible women approached agreed to take part. Two hundred and ninety-eight women in eight clusters participated and 186 termed 'at low risk' for depression, based on an Edinburgh Perinatal Depression Scale (EPDS) score of <12 at 12 weeks gestation, provided baseline and outcome data at 34 weeks gestation. All trial protocol procedures were shown to be feasible. Antenatal effect sizes in women 'at low risk' were similar to those previously demonstrated postnatally. Qualitative work confirmed the acceptability of the approach to CMWs and intervention group women. Conclusion. A fully powered trial testing universal prevention of depression in pregnancy is feasible, acceptable and worth undertaking. [ABSTRACT FROM AUTHOR]

An international double-blind randomized placebo controlled study evaluated the safety and efficacy of four doses of a new sustained release naloxone capsule to treat Opioid Induced Constipation (OIC). Methods Forty patients taking opioids for noncancer related pain, and experiencing OIC, were randomized into 4 cohorts of 10 patients. A multiple ascending dose design was used to evaluate the safety and efficacy of 2.5 mg, 5 mg, 10 mg, and 20 mg naloxone sustained release (NSR) capsules vs placebo. Drug was given once-daily for 3 weeks followed by twice daily (bid) dosing between weeks 4 and 6. Results The incidence of treatment emergent adverse events was highest in the placebo group. The incidence of adverse events among the four active treatment groups were similar. There were no serious adverse events. The number of severe events was low overall but highest in the placebo group. Significant improvements were seen in Spontaneous Bowel Movements with 5 mg, 10 mg, and 20 mg NSR capsules. Mean change in SBMs from baseline of 2.21 ( P = 0.052), 2.37 ( P = 0.032); 4.11 ( P = 0.0005); 5.19 (<0.0001) was noted with NSR 2.5 mg, 5 mg, 10 mg, and 20 mg, respectively, when taken once daily, compared with 1.38 ( P = 0.2) for patients on placebo therapy. No changes in subjective or objective measures of opioid withdrawal as measured by the Subjective Opioid Withdrawal Scale or Clinical Opioid Withdrawal Scale were observed. There was no increase in patient reported pain as measured daily using a visual analogue scale. Conclusions This Phase II study has shown that using a new sustained release formulation to deliver oral naloxone to the colon allows successful treatment of OIC without comprising the desired opioid effects.

BACKGROUND: Epidemiologic data suggest inverse associations between citrus flavanone intake and cardiovascular disease (CVD) risk. However, insufficient randomized controlled trial data limit our understanding of the mechanisms by which flavanones and their metabolites potentially reduce cardiovascular risk factors. OBJECTIVE: We examined the effects of orange juice or a dose-matched hesperidin supplement on plasma concentrations of established and novel flavanone metabolites and their effects on cardiovascular risk biomarkers in men at moderate CVD risk. DESIGN: In an acute, randomized, placebo-controlled crossover trial, 16 fasted participants (aged 51-69 y) received orange juice or a hesperidin supplement (both providing 320 mg hesperidin) or control (all matched for sugar and vitamin C content). At baseline and 5 h postintake, endothelial function (primary outcome), blood pressure, arterial stiffness, cardiac autonomic function, platelet activation, and NADPH oxidase gene expression and plasma flavanone metabolites were assessed. Before each intervention, a diet low in flavonoids, nitrate/nitrite, alcohol, and caffeine was followed, and a standardized low-flavonoid evening meal was consumed. RESULTS: Orange juice intake significantly elevated mean ± SEM plasma concentrations of 8 flavanone (1.75 ± 0.35 μmol/L, P < 0.0001) and 15 phenolic (13.27 ± 2.22 μmol/L, P < 0.0001) metabolites compared with control at 5 h postconsumption. Despite increased plasma flavanone and phenolic metabolite concentrations, cardiovascular risk biomarkers were unaltered. After hesperidin supplement intake, flavanone metabolites were not different from the control, suggesting altered absorption/metabolism compared with the orange juice matrix. CONCLUSIONS: After single-dose flavanone intake within orange juice, circulating flavanone and phenolic metabolites collectively reached a concentration of 15.20 ± 2.15 μmol/L, but no effects were observed on cardiovascular risk biomarkers. Longer-duration randomized controlled trials are required to examine previous associations between higher flavanone intakes and improved cardiovascular health and to ascertain the relative importance of food matrix and flavanone-derived phenolic metabolites. This trial was registered at clinicaltrials.gov as NCT01530893. [ABSTRACT FROM AUTHOR]

Objective Diclofenac is an effective and well-tolerated nonsteroidal anti-inflammatory drug ( NSAID) frequently used in the treatment of acute pain. Marketed formulations for parenteral administration usually contain 75 mg/3 mL of diclofenac sodium, which provide limited dosing flexibility, and are usually given intramuscularly. Methods We present a randomized, double-blind, active comparator- and placebo-controlled, parallel-group phase III multicenter study, investigating efficacy and tolerability of a new 1 mL-volume formulation of diclofenac sodium (25, 50 or 75 mg) containing hydroxypropyl-β-cyclodextrin ( HPβCD) as a solubility enhancer. This low-volume formulation allows subcutaneous ( SC), in addition to intramuscular ( IM) administration. Patients developing moderate-to-severe pain (≥ 50 mm on Visual Analogue Scale) after third molar extraction under local anesthesia were randomized to one of the 4 SC injections: 25 mg diclofenac HPβCD ( n = 77), 50 mg diclofenac HPβCD ( n = 76), 75 mg diclofenac HPβCD ( n = 78), or placebo ( n = 75). Results Mean pain intensity difference at 1.5 hours postdose (primary endpoint) was higher in all diclofenac-treated groups than placebo group. The adjusted means (95% CI) were 36.5 (31.7 to 41.2) in diclofenac 25 mg group, 37.3 (32.6 to 42.1) in diclofenac 50 mg group, 37.7 (33.0 to 42.4) in diclofenac 75 mg group, and 12.3 (7.44 to 17.1) in placebo group. Both 25 and 50 mg doses of diclofenac produced significantly greater pain relief than placebo ( P < 0.001 in both comparisons). Conclusion Single SC doses of diclofenac HPβCD of 25 and 50 mg are effective and well tolerated for relieving pain compared with placebo. [ABSTRACT FROM AUTHOR]

Aim A discussion and qualitative evaluation of the use of peer-review to train nurses and optimize recruitment practice in a randomized controlled trial. Background Sound recruitment processes are critical to the success of randomized controlled trials. Nurses recruiting to trials must obtain consent for an intervention that is administered for reasons other than anticipated benefit to the patient. This requires not only patients' acquiescence but also evidence that they have weighed the relevant information in reaching their decision. How trial information is explained is vital, but communication and training can be inadequate. Design A discussion of a new process to train nurses recruiting to a randomized controlled trial. Data Sources Literature from 1999-2013 about consenting to trials is included. Over 3 months from 2009-2010, recruiting nurses reviewed recruitment interviews recorded during the pilot phase of a single-site randomized controlled trial and noted content, communication style and interactions. They discussed their findings during peer-review meetings, which were audio-recorded and analysed using qualitative methodology. Implications for Nursing Peer-review can enhance nurses' training in trial recruitment procedures by supporting development of the necessary communication skills, facilitating consistency in information provision and sharing best practice. Conclusions Nurse-led peer-review can provide a forum to share communication strategies that will elicit and address participant concerns and obtain evidence of participant understanding prior to consent. Comparing practice can improve consistency and accuracy of trial information and facilitate identification of recruitment issues. Internal peer-review was well accepted and promoted team cohesion. Further evaluation is needed. [ABSTRACT FROM AUTHOR]

The article presents a study which aims to determine the efficiency of a rehabilitation programme over standard physiotherapy practices in the improvement of function in metal-on-metal hip resurfacing arthroplasty patients. It says that the participants completed other measures such as the Hip disability and Osteoarthritis Outcome Score (HOOS), quality of life, and the EuroQol (EQ-5D-3L). It concludes that a tailored physiotherapy approach improves functional outcomes in the patients.

Background: Attention deficit hyperactivity disorder is increased in children with intellectual disability. Previous research has suggested stimulants are less effective than in typically developing children but no studies have titrated medication for individual optimal dosing or tested the effects for longer than 4 weeks. Method: One hundred and twenty two drug-free children aged 7-15 with hyperkinetic disorder and IQ 30-69 were recruited to a double-blind, placebo-controlled trial that randomized participants using minimization by probability, stratified by referral source and IQ level in a one to one ratio. Methylphenidate was compared with placebo. Dose titration comprised at least 1 week each of low (0.5 mg/kg/day), medium (1.0 mg/kg/day) and high dose (1.5 mg/kg/day). Parent and teacher Attention deficit hyperactivity disorder (ADHD) index of the Conners Rating Scale-Short Version at 16 weeks provided the primary outcome measures. Clinical response was determined with the Clinical Global Impressions scale (CGI-I). Adverse effects were evaluated by a parent-rated questionnaire, weight, pulse and blood pressure. Analyses were by intention to treat. Trial registration: ISRCTN 68384912. Results: Methylphenidate was superior to placebo with effect sizes of 0.39 [95% confidence intervals (CIs) 0.09, 0.70] and 0.52 (95% CIs 0.23, 0.82) for the parent and teacher Conners ADHD index. Four (7%) children on placebo versus 24 (40%) of those on methylphenidate were judged improved or much improved on the CGI. IQ and autistic symptoms did not affect treatment efficacy. Active medication was associated with sleep difficulty, loss of appetite and weight loss but there were no significant differences in pulse or blood pressure. Conclusions: Optimal dosing of methylphenidate is practical and effective in some children with hyperkinetic disorder and intellectual disability. Adverse effects typical of methylphenidate were seen and medication use may require close monitoring in this vulnerable group. [ABSTRACT FROM AUTHOR]

Objectives. Cardiovascular disease (CVD) is responsible for 50% of the excess mortality for patients with RA. This study aimed to evaluate a novel 8-week cognitive behavioural patient education intervention designed to effect behavioural change with regard to modifiable CVD risk factors in people with RA.Methods. This was a non-blinded randomized controlled trial with a delayed intervention arm. Participants were randomly assigned to receive the cognitive behavioural education intervention or a control information leaflet at a ratio of 1:1. The primary outcome measure was patient’s knowledge of CVD in RA; secondary measures were psychological measures relating to effecting behaviour change, actual behaviour changes and clinical risk factors. Data were collected at baseline, 2 and 6 months.Results. A total of 110 participants consented (52 in the intervention group and 58 in the control group) to participate in the study. At 6 months, those in the intervention group had significantly higher knowledge scores (P < 0.001); improved behavioural intentions to increase exercise (P < 0.001), eat a low-fat diet (P = 0.01) and lose weight (P = 0.06); and lower mean diastolic blood pressure by 3.7 mmHg, whereas the control group’s mean diastolic blood pressure increased by 0.8 mmHg. There was no difference between the groups on actual behaviours.Conclusions. Patient education has a significant role to play in CVD risk factor modification for patients with RA, and the detailed development of this programme probably contributed to its successful results. It is disappointing that behaviours, as we measured them, did not change. The challenge, as always, is how to translate behavioural intentions into action. Larger studies, powered specifically to look at behavioural changes, are required.Trial registration. National Institute for Health Research, UKCRN 4566. [ABSTRACT FROM PUBLISHER]

Background: Children who show disproportionate difficulty with the pragmatic as compared with the structural aspects of language are described as having pragmatic language impairment (PLI) or social communication disorder (SCD). Some children who have PLI also show mild social impairments associated with high-functioning autism or autism spectrum disorder (ASD). There is little robust evidence of effectiveness of speech-language interventions which target the language, pragmatic or social communication needs of these children. Aims: To evaluate the effectiveness of an intensive manualized social communication intervention (SCIP) for children who have PLI with or without features of ASD. Methods & Procedures: In a single-blind RCT design, 88 children with pragmatic and social communication needs aged 5;11-10;8, recruited from UK speech and language therapy services, were randomly assigned in a 2:1 ratio to SCIP or to treatment-as-usual. Children in the SCIP condition received up to 20 sessions of direct intervention from a specialist research speech and language therapist working with supervised assistants. All therapy content and methodology was derived from an intervention manual. A primary outcome measure of structural language and secondary outcome measures of narrative, parent-reported pragmatic functioning and social communication, blind-rated perceptions of conversational competence and teacher-reported ratings of classroom learning skills were taken pre-intervention, immediately post-intervention and at 6-month follow-up. Analysis was by intention to treat. Outcomes & Results: No significant treatment effect was found for the primary outcome measure of structural language ability or for a measure of narrative ability. Significant treatment effects were found for blind-rated perceptions of conversational competence, for parent-reported measures of pragmatic functioning and social communication, and for teacher-reported ratings of classroom learning skills. Conclusions & Implications: There is some evidence of an intervention effect on blind and parent/teacher-reported communication outcomes, but not standardized language assessment outcomes, for 6-11-year-old children who have pragmatic and social communication needs. These findings are discussed in the context of the increasingly central role of service user outcomes in providing evidence for an intervention. The substantial overlap between the presence of PLI and ASD (75%) across the whole cohort suggests that the intervention may also be applicable to some verbally able children with ASD who have pragmatic communication needs.

Objective: Adults with long-term neurological conditions have low levels of participation in physical activities and report many barriers to participation in exercise. This study examines the feasibility and safety of supporting community exercise for people with long-term neurological conditions using a physical activity support system.Design: A phase II randomized controlled trial using computer-generated block randomization, allocation concealment and single blind outcome assessment.Setting: Oxfordshire and Birmingham community Inclusive Fitness Initiative gyms.Subjects: Patients with a long-term neurological condition.Interventions: The intervention group (n = 51) received a 12-week, supported exercise programme. The control group (n = 48) participants received standard care for 12 weeks and were then offered the intervention.Main measures: Physical activity, adherence to exercise, measures of mobility, health and well-being.Results: Forty-eight patients (n = 51) completed the intervention, achieving 14 gym attendances (range 0–39) over the 12 weeks. Overall activity did not increase as measured by the Physical Activity Scale for the Elderly (change score mean 14.31; 95% confidence interval (CI) −8.27 to 36.89) and there were no statistically significant changes in body function and health and well-being measures.Conclusions: People with long-term neurological conditions can safely exercise in community gyms when supported and achieve similar attendance to standard exercise referral schemes, but may reduce other life activities in order to participate at a gym.

Abstract: This systematic review aims to evaluate the available evidence from randomized clinical trials of the clinical efficacy and safety of ginseng. Systematic literature searches were performed in 13 databases up to March 2009 without language restriction. All randomized clinical trials evaluating the clinical effects or safety of the use of ginseng monopreparations (Panax ginseng or P. quinquefolium) were considered for inclusion. A total of 411 potentially relevant studies were identified and 57 randomized clinical trials were included. The main indications included glucose metabolism, physical performance, psychomotor function, sexual function, cardiac function, pulmonary disease, and cerebrovascular disease. We found strong evidence of a positive effect of ginseng on glucose metabolism, psychomotor function, and pulmonary disease, whereas evidence suggests that ginseng is not effective at enhancing physical performance. However, ginseng generally has a good safety profile and the incidence of adverse effects seems to be low. In conclusion, our review compiles the evidence on the use of ginseng, finding a strong positive potential for glucose metabolism, psychomotor function, and pulmonary disease, but not for physical performance enhancement.

• The intervention was not more effective than services as usual at improving outcomes. • This may relate, in part, to implementation issues; fidelity could be improved. • It may also reflect the relative lack of behavioral components in the program. The aim of the study was to evaluate the implementation and effectiveness of a therapeutic parenting program that targets parents of children aged 6 to 11 years identified as having behavioral and emotional difficulties. The intervention comprises two parts, delivered sequentially: a 10–12-week group-based program for all parents, and one-to-one sessions for up to 12 weeks with selected parents from the group-based element. In a randomized controlled trial, 264 participants were allocated to the Inspiring Futures program (intervention) or services as usual (control) arms with follow-up assessments at 16 (post-group program) and 32 (post-one-to-one sessions) weeks. The primary outcome was the parent-rated Strengths and Difficulties Questionnaire (SDQ) Total Difficulties score at 32 weeks. Secondary outcomes included parent-rated SDQ subscales, parent coping strategies, empathy in parenting and parenting skills. All 264 participants were included in outcome analyses. There was no statistically significant effect on SDQ Total Difficulties (standardized mean difference: −0.07; 95% CI: −0.30 to 0.16; p = 0.54). There were no sub-group effects. Only 1 of 40 comparisons between the trial arms for secondary outcomes across both follow-ups was statistically significant at the 5% level. The mean number of group sessions attended by intervention arm participants was 6.1 (out of 10 to 12) and only 1 in 20 intervention arm participants received one-to-one support. Independent observation indicated scope to improve fidelity in terms of adherence, quality and participant responsiveness. The intervention is not more effective than services as usual at improving targeted outcomes. This may be related, in part, to implementation issues but arguably more to the inability of a non-behavioral intervention to improve caregiving adequately, particularly when it is not targeted at new parents who have experienced trauma or deprivation early in life or subsequently.
