IntroductionTrachomatous trichiasis (TT) is a condition in which the eyelid turns inward and eyelashes abrade the front part of the eye. To prevent eventual blindness, surgery is recommended. Two surgical procedures are commonly used, bilamellar tarsal rotation (BLTR) and posterior lamellar tarsal rotation (PLTR). Evidence suggests that incision height and surgery type may affect the risk of postoperative TT (PTT) and other surgical outcomes. However, these studies have not prospectively compared the impact of incision height on surgical outcomes.Methods and analysisMaximising trichiasis surgery Success (MTSS) is a three-arm, randomised clinical trial being conducted in Ethiopia. Participants will be randomly assigned on a 1:1:1 basis to BLTR with a 3 mm incision height, BLTR with a 5 mm incision height, or PLTR 3 mm incision height. Patients are eligible for the trial if they have previously unoperated upper eyelid TT. Follow-up visits will be conducted by trained eye examiners at 1 day, 2 weeks, 6 weeks and 12 months after surgery. The primary outcome is incident PTT within 1 year following surgery. Logistic regression will be used in an intention-to-treat analysis to assess outcome incidence by surgical approach.Ethics and disseminationThe University of North Carolina and Johns Hopkins School of Medicine institution review boards, Ethiopian National Research Ethics Review Committee and Ethiopian Food, Medicine, Healthcare and Administration and Control Authority provided ethics approval for the trial. On completion, trial results will be disseminated at local and international meetings and in peer-reviewed journals.Trial registration numberNCT03100747.

Background and study aimsPost-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is a complication associated with important morbidity, occasional mortality and high costs. Preventive strategies are suboptimal as PEP continues to affect 4% to 9% of patients. Spraying epinephrine on the papilla may decrease oedema and prevent PEP. This study aimed to compare rectal indomethacin plus epinephrine (EI) versus rectal indomethacin plus sterile water (WI) for the prevention of PEP.Patients and methodsThis multicentre randomised controlled trial included patients aged >18 years with an indication for ERCP and naive major papilla. All patients received 100 mg of rectal indomethacin and 10 mL of sterile water or a 1:10 000 epinephrine dilution. Patients were asked about PEP symptoms via telephone 24 hours and 7 days after the procedure. The trial was stopped half way through after a new publication reported an increased incidence of PEP among patients receiving epinephrine.ResultsOf the 3602 patients deemed eligible, 3054 were excluded after screening. The remaining 548 patients were randomised to EI group (n=275) or WI group (n=273). The EI and WI groups had similar baseline characteristics. Patients in the EI group had a similar incidence of PEP to those in the WI group (3.6% (10/275) vs 5.12% (14/273), p=0.41). Pancreatic duct guidewire insertion was identified as a risk factor for PEP (OR 4.38, 95% CI (1.44 to 13.29), p=0.009).ConclusionSpraying epinephrine on the papilla was no more effective than rectal indomethacin alone for the prevention of PEP.Trial registration numberThis study was registered with ClinicalTrials.gov (NCT02959112).

ObjectivesThe objective of this study was to explore whether reducing the material supplied to external experts during peer review and decreasing the burden of response would maintain review quality into prioritising research questions for a major research funder.Methods and analysisClinical experts who agreed to review documents outlining research for potential commissioning were screened for eligibility and randomised in a factorial design to two types of review materials (long document versus short document) and response modes (structured review form versus free text email response). Previous and current members of the funder’s programme groups were excluded. Response quality was assessed by use of a four-point scoring tool and analysed by intention to treat.Results554 consecutive experts were screened for eligibility and 460 were randomised (232 and 228 to long document or short document, respectively; 230 each to structured response or free text). 356 participants provided reviews, 90 did not respond and 14 were excluded after randomisation as not eligible.The pooled mean quality score was 2.4 (SD=0.95). The short document scored 0.037 (Cohen’s d=0.039) extra quality points over the long document arm, and the structured response scored 0.335 (Cohen’s d=0.353) over free text. The allocation did not appear to have any effect on the experts' willingness to engage with the task.ConclusionsNeither providing a short or a long document outlining suggested research was shown to be superior. However, providing a structured form to guide the expert response provided more useful information than allowing free text. The funder should continue to use a structured form to gather responses. It would be acceptable to provide shorter documents to reviewers, if there were reasons to do so.Trial registration numberANZCTR12614000167662.

ObjectivesTo assess the effectiveness and potential side effects of formula feeding to reduce pain during vaccination among infants.Study designIn the setting of well-baby clinics we recruited a community-based sample of full-term born infants who were already formula fed by the choice of the parents (n=48, aged 4–10 weeks) and received their first DTaP-IPV-HepB-Hib and pneumococcal vaccinations and randomised them into two groups. To evaluate pain experienced during vaccination we compared infants who drank formula feeding before, during and after vaccination with infants who did not. Outcomes were observed cry duration and pain scores measured by means of the Neonatal Infant Pain Scale (NIPS) and the Face, Legs, Activity, Cry and Consolability (FLACC) scale. Side effects of drinking during vaccination were recorded. We performed intention-to-treat analyses using regression models, crude and adjusted for sex and age of the infant.ResultsPain at the moment of the second injection did not differ between groups. Drinking infants cried 33.5 s shorter (−56.6; −10.3). In the first minute after injection drinking infants experienced a faster pain reduction on the NIPSΔt: regression coefficient 3.86 (95% CI 2.70 to 5.02) and FLACCΔt: 4.42 (95% CI 2.85 to 5.99).ConclusionsIn line with findings of previous studies regarding breast feeding, formula feeding reduced vaccination pain in the recovery phase in full-term born infants receiving their first vaccinations between ages 4 and 10 weeks with no adverse effects. Professionals should discuss this non-costly and feasible pain-reducing intervention with parents of infants who receive vaccinations.Trial registration numberIRCTN 31383, post-results

RationalePulmonary rehabilitation (PR) is an effective, key standard treatment for people with COPD. Nevertheless, low participant uptake, insufficient attendance and high drop-out rates are reported. Investigation is warranted of the benefits achieved through alternative approaches, such as pulmonary tele-rehabilitation (PTR).ObjectiveTo investigate whether PTR is superior to conventional PR on 6 min walk distance (6MWD) and secondarily on respiratory symptoms, quality of life, physical activity and lower limb muscle function in patients with COPD and FEV1 <50% eligible for routine hospital-based, outpatient PR.MethodsIn this single-blinded, multicentre, superiority randomised controlled trial, patients were assigned 1:1 to 10 weeks of groups-based PTR (60 min, three times weekly) or conventional PR (90 min, two times weekly). Assessments were performed by blinded assessors at baseline, end of intervention and at 22 weeks’ follow-up from baseline. The primary analysis was based on the intention-to-treat principle.Measurements and main resultsThe primary outcome was change in 6MWD from baseline to 10 weeks; 134 participants (74 females, mean±SD age 68±9 years, FEV1 33%±9% predicted, 6MWD 327±103 metres) were included and randomised. The analysis showed no between-group differences for changes in 6MWD after intervention (9.2 metres (95% CI: −6.6 to 24.9)) or at 22 weeks’ follow-up (−5.3 metres (95% CI: −28.9 to 18.3)). More participants completed the PTR intervention (n=57) than conventional PR (n=43) (χ2 test p<0.01).ConclusionPTR was not superior to conventional PR on the 6MWD and we found no differences between groups. As more participants completed PTR, supervised PTR would be relevant to compare with conventional PR in a non-inferiority design.Trial registration numberClinicalTrials.gov (NCT02667171), 28 January 2016.

AbstractDespite the significant evidence base demonstrating the positive impact of the Promoting Alternative Thinking Strategies (PATHS) curriculum on children’s social-emotional and mental health outcomes, there has been very little research on its efficacy in improving academic attainment. More generally, the relationship between implementation variability and PATHS intervention outcomes has been underexplored. A cluster-randomised controlled trial with two arms: intervention (PATHS – 23 schools) and control (usual practice – 22 schools) was implemented to assess the impact of PATHS on English and Mathematics for children in years 5 (aged 9–10 years, n = 1705 pupils) and 6 (aged 10–11 years, n = 1631 pupils) in English primary schools. Two-level hierarchical linear models (school, child) were used to assess both primary ‘intention-to-treat’ effects and secondary ‘subgroup’ effects (for children eligible for free school meals). Additionally, the moderating role of implementation variability was assessed in 31 year 5 (n = 712 pupils) and 32 year 6 (n = 732 pupils) classes across the 23 intervention schools, with fidelity, dosage, quality/responsiveness and reach data generated via classroom-level structured lesson observations. Intention-to-treat and subgroup analyses revealed no significant positive effect of PATHS on children’s academic attainment. Cluster analyses of observational data revealed four distinct implementation profiles, differentiated primarily by dosage levels. However, these profiles were not significantly associated with differential academic outcomes. In light of our findings and their likely generalisability, it is not possible to recommend PATHS as an effective intervention for improving the academic attainment of children in English primary schools.Trial registration: ISRCTN85087674

ObjectivesThere are no head-to-head trials of different dose escalation strategies of methotrexate (MTX) in RA. We compared the efficacy, safety and tolerability of ‘usual’ (5 mg every 4 weeks) versus ‘fast’ (5 mg every 2 weeks) escalation of oral MTX.MethodsThis multicentre, open-label (assessor blinded) RCT included patients 18-55 years of age having active RA with disease duration <5 years, and not on DMARDs. Patients were randomized 1:1 into usual or fast escalation groups, both groups starting MTX at 15 mg/week till a maximum of 25 mg/week. Primary outcome was EULAR good response at 16 weeks, secondary outcomes were ΔDAS28 and adverse effects (AE). Analyses were intention-to-treat.Results178 patients with mean DAS28-CRP of 5.4(1.1) were randomized to usual (n=89) or fast escalation groups (n=89). At 16 weeks, there was no difference in good EULAR response in the usual (28.1%) or fast escalation (22.5%) groups (p=0.8). There was no difference in mean ΔDAS28-CRP at 8 weeks (-0.9, -0.8, p=0.72) or 16 weeks (-1.3, -1.3, p=0.98). Even at 24 weeks (extended follow-up), responses were similar. There were no inter-group differences in ΔHAQ, or MTX-polyglutamates 1-3 levels at 8 or 16 weeks. Gastrointestinal AE were higher in the fast escalation group over initial 8 weeks (27%, 40%, p=0.048), but not over 16 weeks. There was no difference in cytopenias, transaminitis, or drug discontinuation/dose reduction between the groups. No serious AE were seen.ConclusionA faster MTX escalation strategy in RA was not more efficacious over 16-24 weeks, and did not significantly increase AE, except higher gastrointestinal AE initially.Trial registration numberCTRI/2018/12/016549

IntroductionEmergency intubation of children with abnormal respiratory or cardiac physiology is a high-risk procedure and associated with a high incidence of adverse events including hypoxemia. Successful emergency intubation is dependent on inter-related patient and operator factors. Preoxygenation has been used to maximise oxygen reserves in the patient and to prolong the safe apnoeic time during the intubation phase. Transnasal Humidified Rapid Insufflation Ventilatory Exchange (THRIVE) prolongs the safe apnoeic window for a safe intubation during elective intubation. We designed a clinical trial to test the hypothesis that THRIVE reduces the frequency of adverse and hypoxemic events during emergency intubation in children and to test the hypothesis that this treatment is cost-effective compared with standard care.Methods and analysisThe Kids THRIVE trial is a multicentre randomised controlled trial performed in participating emergency departments and paediatric intensive care units. 960 infants and children aged 0–16 years requiring emergency intubation for all reasons will be enrolled and allocated to THRIVE or control in a 1:1 allocation with stratification by site, age (<1, 1–7 and >7 years) and operator (junior and senior). Children allocated to THRIVE will receive weight appropriate transnasal flow rates with 100% oxygen, whereas children in the control arm will not receive any transnasal oxygen insufflation. The primary outcomes are defined as follows: (1) hypoxemic event during the intubation phase defined as SpO2<90% (patient-dependent variable) and (2) first intubation attempt success without hypoxemia (operator-dependent variable). Analyses will be conducted on an intention-to-treat basis.Ethics and disseminationEthics approval for the protocol and consent process has been obtained (HREC/16/QRCH/81). The trial has been actively recruiting since May 2017. The study findings will be submitted for publication in a peer-reviewed journal.Trial registration numberACTRN12617000147381.

IntroductionEarly medical abortion (EMA) is a two-stage process of terminating pregnancy using oral mifepristone (a progesterone-receptor antagonist) followed usually 1–2 days later by sublingual, vaginal or buccal misoprostol (a prostaglandin analogue). There are no published randomised controlled trials (RCTs) on the use of telemedicine for EMA. Our proposed research will determine if telephone consultations for EMA (the most common method of abortion in the UK) is non-inferior to standard face-to-face consultations with regard to the efficacy of EMA.Methods and analysisThis study will be conducted as an RCT. The recruitment target is 1222 participants.The primary outcome is success of EMA (complete abortion rate). This will be determined based on a negative low-sensitivity urine pregnancy test result (2 weeks after misoprostol use) and absence of surgical intervention or diagnosis of ongoing pregnancy (within 6 weeks of misoprostol).Secondary outcomes include total time spent at a clinic appointment to receive EMA, self-reported preparedness for EMA, level of satisfaction with consultation and effective contraception uptake compared with when women attend for a face-to-face consultation.The main analysis will be a modified intention-to-treat analysis. This will include all randomised women (with a viable pregnancy) using EMA and follow-up for the main outcome. The study initiated on 13 January 2020 and is anticipated to finish in late 2021.Ethics and disseminationEthical approval was given by the South East Scotland NHS Research Ethics Committee, reference: 19/SS/0111. Results will be published in peer-reviewed journals, presented at clinical and academic meetings, and shared with participants via the clinic website.Trial registration numberNCT04139382.

Abstract The presence of civilian witnesses and victims in court is central to the effective operation of the criminal justice system. However, there is evidence of significant non-attendance which can result in ineffective and cracked trials. To address this, West Midlands Police Witness Care Unit and the Behavioural Insights Team designed an intervention using behavioural insight principles consisting of (1) a new conversation guide for Witness Care Officers (WCOs); (2) a redesigned ‘Warning Letter’ confirming details of the proceedings; and (3) a new reminder call and SMS. The impact of the new approach was evaluated through a randomised controlled trial in which 36 WCOs were randomly assigned to either “business as usual” (control) or treatment. The evaluation used an intention-to-treat design with implementation guided and encouraged at several points. Subgroup analysis was undertaken to explore whether differential effects were seen for domestic violence cases or between those that were victims and witnesses. Results indicated that the treatment approach was directionally positive in all cases, but that the increase in attendance was not statistically significant. This is in line with findings of other similar research in this area.

IntroductionTemporomandibular disorders (TMDs) are considered a collection of musculoskeletal conditions involving the masticatory muscles, the temporomandibular joint and associated structures. The myogenous group appears to represent the most frequently diagnosed category. In the context of a multimodal approach, splint therapy and musculoskeletal physiotherapy are often considered as a preferred therapy. The purpose of this study will be to investigate the effects of musculoskeletal physiotherapy combined with occlusal splint and education versus occlusal splint and education alone in the treatment of chronic myogenous TMD on pain and mandibular range of motion.Methods and analysisAll consecutive adults complaining of TMDs presented to the Department of Biomedical and Neuromotor Sciences of the University of Bologna will be considered eligible. Inclusion criteria shall be based on the presence of myogenous TMDs, as diagnosed through clinical examination in reference to the international diagnostic criteria of TMDs. Randomisation, concealed allocation, blinded assessment and intention-to-treat analysis will be employed. The splint therapy will consist of the use of the splint every night and concurrent delivery of an educational programme; the protocol shall have a duration of three consecutive months. The combined musculoskeletal physiotherapy, splint therapy and education will additionally consist of manual therapy techniques and exercise; such protocol shall consist of a duration of three consecutive months, inclusive of 10 sessions for the enhanced elements. All outcome measures will be collected at baseline, after treatment and at a 6 months follow-up.Ethics and disseminationEthical approval has been obtained from the Independent Ethic Committee in Clinical Research of AUSL Bologna-Italy (47/2018/SPER/AUSLBO). Pursuant to applicable rules,we will obtain informed consent from each participant and collect data anonymously to maintain privacy. Results will be disseminated to clinicians and researchers through peer-reviewed publications and conferences.Trial registration numberNCT03726060
