INTRODUCTION: Exercise and physical activity (PA) are fundamental to the treatment of type 2 diabetes. Current exercise and PA strategies for newly diagnosed individuals with type 2 diabetes are either clinically effective but unsuitable in routine practice (supervised exercise) or suitable in routine practice but clinically ineffective (PA advice). Mobile health (mHealth) technologies, offering biometric data to patients and healthcare professionals, may bridge the gap between supervised exercise and PA advice, enabling patients to engage in regular long-term physically active lifestyles. This feasibility randomised controlled trial (RCT) will evaluate the use of mHealth technology when incorporated into a structured home-based exercise and PA intervention, in those recently diagnosed with type 2 diabetes. METHODS AND ANALYSIS: This feasibility multicentre, parallel group RCT will recruit 120 individuals with type 2 diabetes (diagnosis within 5-24 months, aged 40-75 years) in the UK (n=60) and Canada (n=60). Participants will undertake a 6-month structured exercise and PA intervention and be supported by an exercise specialist (active control). The intervention group will receive additional support from a smartwatch and phone app, providing real-time feedback and enabling improved communication between the exercise specialist and participant. Primary outcomes are recruitment rate, adherence to exercise and loss to follow-up. Secondary outcomes include a qualitative process evaluation and piloting of potential clinical outcome measures for a future RCT. ETHICS AND DISSEMINATION: The trial was approved in the UK by the South East Scotland Research Ethics Committee 01 (20/SS/0101) and in Canada by the Clinical Research Ethics Board of the University of British Columbia (H20-01936), and is being conducted in accordance with the Declaration of Helsinki and Good Clinical Practice. Results will be published in peer-reviewed journals and presented at national and international scientific meetings. TRIAL REGISTRATION NUMBERS: ISRCTN14335124; ClinicalTrials.gov: NCT04653532.

OBJECTIVES: The aim of the project was to examine the acceptability and feasibility of a mobile phone application-based intervention 'TechCare', for individuals with psychosis in the North West of England. The main objectives were to determine whether appropriate individuals could be identified and recruited to the study and whether the TechCare App would be an acceptable intervention for individuals with psychosis. METHODS: This was a mixed methods feasibility study, consisting of a test-run and feasibility evaluation of the TechCare App intervention. SETTING: Early Intervention Services (EIS) for psychosis, within an NHS Trust in the North West of England. PARTICIPANTS: Sixteen participants (test-run n=4, feasibility study n=12) aged between 18 and 65 years recruited from the East, Central and North Lancashire EIS. INTERVENTION: A 6-week intervention, with the TechCare App assessing participants' symptoms and responses in real-time and providing a personalised-guided self-help-based psychological intervention based on the principles of Cognitive Behaviorual Therapy (CBT). RESULTS: A total of 83.33% (n=10) of participants completed the 6-week feasibility study, with 70% of completers achieving the set compliance threshold of ≥33% engagement with the TechCare App system. Analysis of the qualitative data suggested that participants held the view that the TechCare was both an acceptable and feasible means of delivering interventions in real-time. CONCLUSION: Innovative digital clinical technologies, such as the TechCare App, have the potential to increase access to psychological interventions, reduce health inequality and promote self-management with a real-time intervention, through enabling access to mental health resources in a stigma-free, evidence-based and time-independent manner.

OBJECTIVES: To explore the reasons why healthcare workers migrate from Syria, a country where conflict has been raging for over a decade. DESIGN: A qualitative study was performed using semistructured interviews. Semistructured questions guided in-depth interviews. Content analysis was used. SETTING: Participants were Syrian healthcare workers who had worked in the country after the conflict started in 2011, but at some point left Syria and settled abroad. The interviews took place in Turkey and Europe in 2016 and 2017. PARTICIPANTS: We collected data from 20 participants (18 males and 2 females) through snowball sampling method. RESULTS: Healthcare workers migrated from Syria only because of security reasons. In most cases, the decision to leave resulted from the generalised violence against civilians by different warring parties, mainly the Government of Syria and the Islamic State. Intentional attacks against healthcare workers were also one of the main reasons for leaving. Some participants had a specific notable trigger event before leaving, such as colleagues being detained or killed. Many participants simply grew tired of living under constant fear, with their families also at risk. CONCLUSIONS: This research adds to the body of literature on violence against healthcare workers in Syria. It helps to understand the reasons why healthcare workers leave the country. The study also indicates that the international community has failed to protect Syrian healthcare workers. The intensity of the conflict has left many healthcare workers with no other option than to leave. Understanding this migration will enable the discovery of new solutions for protecting healthcare workers in current and future conflicts.

OBJECTIVE: Pharmacists are increasingly contributing to the skill mix of general practice surgeries to help alleviate pressures faced by UK doctors working in primary care. However, they need support in overcoming barriers to their integration. The purpose of this work was to evaluate a programme designed to support pharmacists' transition to working in general practice settings. We explored the learning needs of pharmacists', the barriers and enablers to their integration and provide recommendations based on our results. INTERVENTION: A qualitative evaluation of a 1-year transition programme in Wales starting in September 2018 to support pharmacists' transition to working in general practice settings. DESIGN AND SETTING: We employed an interpretative phenomenological approach involving 10 pharmacists across Wales enrolled on the transition to general practice training programme, and their tutors. Data were collected across two sequential phases: in phase 1 telephone interviews were held with pharmacists midway through their training; in phase 2, focus groups were conducted with both pharmacists and tutors towards the end of the programme. RESULTS: Pharmacists enter general practice settings with a variety of prior experience. The programme provided a framework that pharmacists found helpful to map their experience to but the programme needed to be flexible to individual learning needs. The tutor role was typically regarded as the most valuable component, but interaction with the wider general practice team was critical to ease the transition. Pharmacists encountered a lack of clarity about their role which impeded their integration into the workplace team. CONCLUSIONS: A formal programme with a designated tutor can support pharmacists' transition into general practice settings. The programme's competency framework facilitated reciprocal understanding of the pharmacist's role in the team, helped to manage expectations and enhanced collaborative practice. Recommendations to facilitate pharmacist integration into general practice settings are provided.

OBJECTIVES: To assess the effects of integrated models of care for people with multimorbidity including at least diabetes or hypertension in low-income and middle-income countries (LMICs) on health and process outcomes. DESIGN: Systematic review. DATA SOURCES: We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, LILACS, Africa-Wide, CINAHL and Web of Science up to 12 December 2019. ELIGIBILITY CRITERIA: We included randomised controlled trials (RCTs), non-RCTs, controlled before-and-after studies and interrupted time series (ITS) studies of people with diabetes and/or hypertension plus any other disease, in LMICs; assessing the effects of integrated care. DATA EXTRACTION AND SYNTHESIS: Two authors independently screened retrieved records; extracted data and assessed risk of bias. We conducted meta-analysis where possible and assessed certainty of evidence using Grading of Recommendations Assessment, Development and Evaluation. RESULTS: Of 7568 records, we included five studies-two ITS studies and three cluster RCTs. Studies were conducted in South Africa (n=3), Uganda/Kenya (n=1) and India (n=1). Integrated models of care compared with usual care may make little or no difference to mortality (very low certainty), the number of people achieving blood pressure (BP) or diabetes control (very low certainty) and access to care (very low certainty); may increase the number of people who achieve both HIV and BP/diabetes control (very low certainty); and may have a very small effect on achieving HIV control (very low certainty). Interventions to promote integrated delivery of care compared with usual care may make little or no difference to mortality (very low certainty), depression (very low certainty) and quality of life (very low certainty); and may have little or no effect on glycated haemoglobin (low certainty), systolic BP (low certainty) and total cholesterol levels (low certainty). CONCLUSIONS: Current evidence on the effects of integrated care on health outcomes is very uncertain. Programmes and policies on integrated care must consider context-specific factors related to health systems and populations. PROSPERO REGISTRATION NUMBER: CRD42018099314.

OBJECTIVE: The relationship between Helicobacter pylori and the intestinal microbiota has not yet been clearly demonstrated in children and adolescents. The present study aimed at evaluating how H. pylori infection could affect the intestinal microbiota in adolescents using genetic analysis. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: We included subjects from a longitudinal project involving H. pylori screening and treatment of junior high school third-grade students (aged 14 or 15 years) in Saga Prefecture. The study included a control group (n=79) and an H. pylori group (n=80) tested negative and positive for the anti-H. pylori antibody in the urine and H. pylori antigen in stool specimens, respectively. INTERVENTIONS: The intestinal microbiota was evaluated in stool specimens using 16S rRNA gene/DNA/amplicon sequencing with next-generation sequencing. PRIMARY AND SECONDARY OUTCOME MEASURES: We assessed alpha and beta diversity, just as well as relative abundances within the bacterial composition at the genus level in both groups. RESULTS: As shown by the alpha diversity of the 16S rRNA gene/DNA/amplicon sequence data, the control group exhibited lower microbial species richness with lower alpha diversity compared with the H. pylori group (p<0.001). The beta diversity of the intestinal microbiota profile also differed between the two groups (p<0.01). The relative abundance of the Prevotella genus was higher in the H. pylori group (p<0.01) concomitant with a gain in body mass index (BMI) in the H. pylori group (p<0.01) compared with the control group. CONCLUSION: H. pylori infection significantly affected the intestinal microbiota in Japanese adolescents. In addition, the prevalence of the Prevotella genus is concomitantly increased along with the BMI in H. pylori-infected students. TRIAL REGISTRATION NUMBER: UMIN000028721.

OBJECTIVE: Informal family caregivers play a crucial role in cancer care. Effective caregiver involvement in cancer care can improve both patient and caregiver outcomes. Despite this, interventions improving the caregiver involvement are sparse. This protocol describes a randomised controlled trial evaluating the combined effectiveness of novel online caregiver communication education modules for: (1) oncology clinicians (eTRIO) and (2) patients with cancer and caregivers (eTRIO-pc). METHODS AND ANALYSIS: Thirty medical/radiation/surgical oncology or haematology doctors and nurses will be randomly allocated to either intervention (eTRIO) or control (an Australian State Government Health website on caregivers) education conditions. Following completion of education, each clinician will recruit nine patient-caregiver pairs, who will be allocated to the same condition as their recruiting clinician. Eligibility includes any new adult patient diagnosed with any type/stage cancer attending consultations with a caregiver. Approximately 270 patient-caregiver pairs will be recruited. The primary outcome is caregiver self-efficacy in triadic (clinician-patient-caregiver) communication. Patient and clinician self-efficacy in triadic communication are secondary outcomes. Additional secondary outcomes for clinicians include preferences for caregiver involvement, perceived module usability/acceptability, analysis of module use, satisfaction with the module, knowledge of strategies and feedback interviews. Secondary outcomes for caregivers and patients include preferences for caregiver involvement, satisfaction with clinician communication, distress, quality of life, healthcare expenditure, perceived module usability/acceptability and analysis of module use. A subset of patients and caregivers will complete feedback interviews. Secondary outcomes for caregivers include preparedness for caregiving, patient-caregiver communication and caring experience. Assessments will be conducted at baseline, and 1 week, 12 weeks and 26 weeks post-intervention. ETHICS AND DISSEMINATION: Ethical approval has been received by the Sydney Local Health District Human Research Ethics Committee (REGIS project ID number: 2019/PID09787), with site-specific approval from each recruitment site. Protocol V.7 (dated 1 September 2020) is currently approved and reported in this manuscript. Findings will be disseminated via presentations and peer-reviewed publications. Engagement with clinicians, media, government, consumers and peak cancer groups will facilitate widespread dissemination and long-term availability of the educational modules.

INTRODUCTION: Sarcomas are rare tumours with considerable heterogeneity. Early and accurate diagnosis is important to optimise patient outcomes in terms of local disease control, overall survival (OS) and health-related quality of life (HRQoL). Time to diagnosis is variable in bone as well as soft tissue sarcoma. Possible factors for a long time from first symptom to diagnosis (the total interval) include patient, tumour and healthcare characteristics, but until now the most relevant risk factors and its association with outcomes remain unknown. Our study aims to (1) quantify total interval, the time interval from first symptom until (histological) diagnosis; (2) identify factors associated with interval length and (3) determine the association between total interval and HRQoL, stage and tumour size at diagnosis, progression-free survival (PFS) and OS. METHODS AND ANALYSIS: We will conduct a longitudinal, prospective, international, multicentre cohort study among patients aged ≥18 years with newly diagnosed bone or soft tissue sarcoma at eight centres (three in UK, five in The Netherlands). Patients will be asked to complete questionnaires at five points in time; one at diagnosis and at follow-up points of 3, 6, 12 and 24 months. Questionnaire data is collected within the Patient Reported Outcomes Following Initial treatment and Long term Evaluation of Survivorship (PROFILES) registry: an international data management system for collection of patient-reported outcomes. Clinical data will be extracted from patient records. The primary endpoint is HRQoL at diagnosis, measured with the EORTC QLQ-C30. Secondary endpoints are stage and tumour size at diagnosis, PFS, OS, additional patient-reported outcomes, such as quality-adjusted life years and psychological distress. ETHICS AND DISSEMINATION: Ethical approval was given by the Health Research Authority and Research Ethics Committee for the United Kingdom (18/WA/0096) and medical ethical committee of Radboudumc for The Netherlands (2017-3881). Results will be presented in peer-reviewed journals and presented at meetings. TRIAL REGISTRATION NUMBER: NCT03441906.

INTRODUCTION: Hepatitis C virus (HCV) is a global public health threat, and novel models of care are required to treat those currently or previously at highest risk of infection, particularly persons who inject drugs (PWID; ever injected), as conventional healthcare models do not have the reach to deliver cure of HCV to disadvantaged, disproportionately affected communities. In Western Europe and Australasia, it is estimated that HCV affects between 0.4% and 1.0% of the regions' populations, accordingly, it affects between 0.4% and 0.7% of the populations of countries in this study (Scotland, Wales and Australia). Reaching mEthadone users Attending Community pHarmacies with HCV (REACH HCV) will evaluate community pharmacy-based diagnostic outreach and HCV treatment against conventional HCV testing and treatment pathways for clients receiving opioid substitution therapy (OST) in community pharmacies. METHODS AND ANALYSIS: REACH HCV is an international multicentre cluster randomised controlled trial with sites in Scotland, Wales and Australia. The sites are community pharmacies which are randomised equally to one of two pathways: the pharmacy intervention pathway or the education-only (control) pathway. Participants are recruited from OST clients in these pharmacies.In the pharmacy intervention pathway, participants receive a rapid point-of-care HCV PCR test in their pharmacy by a study outreach nurse. If positive, direct-acting antivirals (DAAs) are delivered to participants via their pharmacist in line with their OST schedule.In the education-only pathway, pharmacists counsel OST clients on HCV and refer them to the nearest nurse-led clinic or general practitioner offering HCV testing according to standard care protocols. If positive, DAAs are delivered as in the intervention pathway.The primary endpoint for both pathways is sustained viral response at 12 weeks post-treatment . Secondary outcomes are: cost-efficacy by pathway; participants tested by pathway; adherence to therapy by pathway and impact of blood test results on treatment decisions.A statistical analysis plan will be finalised prior to data lock. Analysis will be by intention to treat (ITT) to show superiority. Modified ITT analysis will also be undertaken to explore the steps in the pathways. ETHICS AND DISSEMINATION: The trial received ethical favourable opinion from the East of Scotland Research Ethics Committee 2 (19/ES/0025) for UK sites and approval from the Alfred Hospital Ethics Committee (148/19) for Australian sites and complies with principles of Good Clinical Practice. Final results will be presented in peer-reviewed journals and at relevant conferences. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry NCT03935906. PROTOCOL VERSION: V.4.0-19 March 2020.

OBJECTIVES: Chlamydia trachomatis is a public health problem. Widespread testing and re-testing after a sexually transmitted infection (STI) is recommended to contain the epidemic and has been adopted by many countries. A recent study in Stockholm found that serial testing was used as a substitute for condom use by youth presenting at the Youth Health Clinics (YHC). The objectives of this study are to explore frontline healthcare provider's perception of youth testing repeatedly for C. trachomatis as a substitute for condom use and their views on how this might be addressed. DESIGN: Qualitative study, in-depth interviews and analysed using content analysis. SETTING: YHC in Stockholm County, Sweden. PARTICIPANTS: Healthcare providers (HCPs) working at the YHC. FINDINGS: Testing used as a method of prevention of STIs by youth has been a well-known phenomenon observed by HCPs at the YHC. Despite frustration regarding this behaviour, attitudes towards youth visiting the clinics repeatedly were overall positive. It is seen as an opportunity to reach youth with primary prevention strategies. Time for in-depth conversations with the youth is considered essential to understand the various reasons behind sexual risk-taking and to tailor counselling accordingly. Introducing concepts of self-compassion and self-respect in relation to sex is thought of as an effective intervention to improve sexual health among youth. CONCLUSION: HCPs' views on testing repeatedly for C. trachomatis as means of prevention, range widely from seeing this as 'a positive strategy for C. trachomatis prevention' to 'a waste of healthcare resources'. There was a more unified view on how this should be addressed. Testing without having time to problematise sexual risk-taking was seen as meaningless. In depth, one-on-one counselling was deemed important. While scaling up accessibility to testing services, primary prevention strategies must not be neglected.

OBJECTIVES: This study aimed to determine the seroprevalence of Toxoplasma gondii (T. gondii) infection in pregnant women in Matehuala City, Mexico; and the associated risk factors. DESIGN: A cross-sectional study. SETTING: Matehuala City, Mexico. PARTICIPANTS: 311 pregnant women. PRIMARY AND SECONDARY OUTCOME MEASURES: Sera of women were analysed for anti-T. gondii IgG and IgM antibodies by commercially available immunoassays. Bivariate and multivariate analyses were used to assess the association between T. gondii seroprevalence and the characteristics of the pregnant women. RESULTS: Thirteen (4.2%) of the 311 pregnant women studied were positive for anti-T. gondii IgG antibodies. No anti-T. gondii IgM antibodies were found in anti-T. gondii IgG seropositive women. No association between seropositivity and history of blood transfusion, transplantation, caesarean sections, deliveries, miscarriages or number of pregnancies was found. Logistic regression analysis of sociodemographic, behavioural and housing variables showed that availability of potable water at street represented a risk factor for T. gondii infection (age-adjusted OR=2.18; 95% CI: 1.05 to 4.53; p=0.03), whereas being born in Mexico was a protective factor for infection (age-adjusted OR=0.01; 95% CI: 0.001 to 0.35; p=0.008). CONCLUSIONS: In this first study on the seroepidemiology of T. gondii infection in pregnant women in Matehuala, we conclude that the seroprevalence of T. gondii infection is low and similar to those reported in pregnant women in other Mexican cities. However, the seroprevalence found is lower than those reported in pregnant women in other countries in the Americas and Europe. Two risk factors associated with T. gondii infection were identified. Results of the present study may help for the optimal planning of preventive measures against toxoplasmosis in pregnant women.

INTRODUCTION: Lower urinary tract symptoms (LUTS) is a bothersome condition affecting older men which can lead to poor quality of life. General practitioners (GPs) currently have no easily available assessment tools to help effectively diagnose causes of LUTS and aid discussion of treatment with patients. Men are frequently referred to urology specialists who often recommend treatments that could have been initiated in primary care. GP access to simple, accurate tests and clinician decision tools are needed to facilitate accurate and effective patient management of LUTS in primary care. METHODS AND ANALYSIS: PRImary care Management of lower Urinary tract Symptoms (PriMUS) is a prospective diagnostic accuracy study based in primary care. The study will determine which of a number of index tests used in combination best predict three urodynamic observations in men who present to their GP with LUTS. These are detrusor overactivity, bladder outlet obstruction and/or detrusor underactivity. Two cohorts of participants, one for development of the prototype diagnostic tool and other for validation, will undergo a series of simple index tests and the invasive reference standard (invasive urodynamics). We will develop and validate three diagnostic prediction models based on each condition and then combine them with management recommendations to form a clinical decision support tool. ETHICS AND DISSEMINATION: Ethics approval is from the Wales Research Ethics Committee 6. Findings will be disseminated through peer-reviewed journals and conferences, and results will be of interest to professional and patient stakeholders. TRIAL REGISTRATION NUMBER: ISRCTN10327305.

INTRODUCTION: Nutritional intervention and prevention of malnutrition is significantly important for patients with upper gastrointestinal oesophageal, pancreatic and gastric cancer. However, there is limited information regarding nutritional status, and perioperative nutritional interventions that patients receive when undergoing curative surgery. METHODS AND ANALYSIS: Patients diagnosed with upper gastrointestinal cancer, planned for curative intent resection across 27 Australian hospitals will be eligible to participate in this point prevalence study. The primary aim is to determine the prevalence of malnutrition in patients with upper gastrointestinal cancer at the time of surgery using subjective global assessment. Secondary aims are to determine the type and frequency of perioperative nutritional intervention received, the prevalence of clinically important weight loss and low muscle strength, and to investigate associations between the use of an evidence-based nutrition care pathway or protocol for the nutritional management of upper gastrointestinal surgical oncology patients and malnutrition prevalence. Data collection will be completed using a purpose-built data collection tool. ETHICS AND DISSEMINATION: Ethical approval was granted in May 2019 (LNR/51107/PMCC-2019). The design and reporting of this study comply with the Strengthening the Reporting of Observational Studies in Epidemiology checklist for reporting of observational cohort studies. Findings will be published in peer-reviewed scholarly journals and presented at relevant conferences. Results will assist in defining priority areas for research to improve patient outcomes.

INTRODUCTION: Interparental conflict exposure places adolescents at risk for problems with stress and anxiety; existing prevention/intervention strategies focus on reducing interparental conflict. Mindfulness-based programmes may be a promising treatment strategy for this population, but studies have not yet tested whether they are effective in this high-conflict context. In addition, evidence suggests that extensions to traditional treatments, such as delivering components in daily life that are tailored to moments of need, can increase treatment efficacy, particularly when combined with in-person treatments and particularly for adolescents. However, there are no such extensions to mindfulness interventions available. The Moving 2 Mindful study aims to (1) develop an ecological momentary intervention (EMI) supplement to Learning to BREATHE (L2B), an evidence-based mindfulness intervention for adolescents; (2) refine the EMI programme and determine the best delivery plan; (3) examine the feasibility and acceptability of L2B Plus (L2B plus the developed supplement) and (4) examine the potential for L2B Plus to reduce stress and anxiety for adolescents from high-conflict homes. METHODS AND ANALYSIS: The Moving 2 Mindful study proposes a mixed-methods approach to developing and refining a multimethod adaptive supplement to L2B. Feasibility, acceptability and potential effectiveness will be tested in a sample of 38 families, who will be randomly assigned to receive L2B Plus or an active health and wellness control condition and followed until 3 months postintervention. A range of psychosocial and physiological factors will be assessed at multiple time points. This study is registered with clinicaltrials.gov (ID NCT03869749; pre-results). ETHICS AND DISSEMINATION: The Institutional Review Board at Colorado State University has approved this study. Findings will be disseminated in scientific journals and conferences, whether they are positive, negative or inconclusive.

INTRODUCTION: Hypoxaemia during anaesthesia for tubeless upper airway surgery in children with abnormal airways is common due to the complexity of balancing adequate depth of anaesthesia with maintenance of spontaneous breathing and providing an uninterrupted field of view of the upper airway for the surgeon. High-flow nasal oxygenation (HIGH-FLOW) can prolong safe apnoea time and be used in children with abnormal airways but to date has not been compared with the alternative technique of low-flow nasal oxygenation (LOW-FLOW). The aim is to investigate if use of HIGH-FLOW can reduce the number of hypoxaemic events requiring rescue oxygenation compared with LOW-FLOW. METHODS AND ANALYSIS: High-flow oxygen for children's airway surgery: randomised controlled t rial (HAMSTER) is a multicentre, unmasked, randomised controlled, parallel group, superiority trial comparing two oxygenation techniques during anaesthesia. Children (n=530) aged >37 weeks to 16 years presenting for elective tubeless upper airway surgery who fulfil inclusion but not exclusion criteria will be randomised prior to surgery to HIGH-FLOW or LOW-FLOW post induction of anaesthesia. Maintenance of anaesthesia with HIGH-FLOW requires Total IntraVenous Anaesthesia (TIVA) and with LOW-FLOW, either inhalational or TIVA at discretion of anaesthetist. The primary outcome is the incidence of hypoxaemic events requiring interruption of procedure for rescue oxygenation by positive pressure ventilation and the secondary outcome includes total hypoxaemia time, adverse cardiorespiratory events and unexpected paediatric intensive care admission admission. Hypoxaemia is defined as Sp02 <90%. Analysis will be conducted on an intention-to-treat basis. ETHICS AND DISSEMINATION: Ethical approval has been obtained by Children's Health Queensland Human Research Ethics Committee (HREC/18/QRCH/130). The trial commenced recruitment in 2018. The primary manuscript will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: The HAMSTER is registered with the Australia and New Zealand Clinical TrialsRegistry: ACTRN12618000949280.

OBJECTIVES: Recent meta-analyses of eradication therapy in Helicobacter pylori-infected adults reported significant reductions in gastric carcinoma risk. However, concerns about supporting unfocused screening and eradication programme in healthy, asymptomatic populations have arisen. We performed a systematic review and Bayesian meta-analysis to provide an accurate interpretation of randomised evidence on the preventive effectiveness of eradication therapy on gastric carcinoma risk. METHODS: We searched databases including PubMed, Cochrane Central and Embase for reference and citation tracking without language restrictions, from inception through 31 July 2018. Paired investigators independently selected randomised controlled trials (RCTs) comparing eradication therapy with placebo or no treatment for asymptomatic or dyspeptic H. pylori-infected adults with no previous gastric carcinoma. The main outcome was gastric carcinoma incidence; secondary outcomes included gastric carcinoma-specific, non-gastric carcinoma and all-cause mortality. RESULTS: A total of 5 population-based and 2 outpatient care-based RCTs involving 7303 adults were eligible. Eradication algorithms were heterogeneous, and unsuccessful eradication and reinfection were frequently observed. A Bayesian meta-analysis with competing risk outcomes found low-certainty evidence that eradication therapy might be more likely than control to reduce gastric carcinoma risk (HR=0.65; 95% credible interval (CrI) 0.41 to 1.0; I2 =11%). The CrIs included the null effects across the subgroup and sensitivity analyses, apart from those based on particular models that excluded two RCTs that enrolled subjects with specific histological findings only (HR=0.55; CrI 0.30 to 0.89; I2 =14%). The uncertainty of the average 41% risk reduction in gastric carcinoma-specific mortality included a clinically important mortality risk increase (HR=0.59 favouring eradication therapy; CrI 0.25 to 1.20; I2 =13%; low certainty). CONCLUSIONS: There is insufficient evidence to support or refute the effectiveness of eradication therapy in preventing gastric carcinoma in H. pylori-infected, high-risk populations. Rigorously conducted large RCTs of healthy infected adults only would provide evidence of the true efficacy of successful eradication. PROSPERO registration number: CRD42014009245.

INTRODUCTION: The aged population is increasing rapidly across the world and this is expected to continue. People living in residential aged care facilities (RACFs) represent amongst the sickest and frailest cohort of the aged population, with a high prevalence of chronic conditions and complex comorbidities. Given the vulnerability of RACF residents and the demands on the system, there is a need to determine the extent that care is delivered in line with best practice ('appropriate care') in RACFs. There is also a recognition that systems should provide care that optimises quality of life (QoL), which includes support for physical and psychological well-being, independence, social relationships, personal beliefs and a caring external environment. The aims of CareTrack Aged are to develop sets of indicators for appropriate care and processes of care for commonly managed conditions, and then assess the appropriateness of care delivered and QoL of residents in RACFs in Australia. METHODS AND ANALYSIS: We will extract recommendations from clinical practice guidelines and, using expert review, convert these into sets of indicators for 15 common conditions and processes of care for people living in RACFs. We will recruit RACFs in three Australian states, and residents within these RACFs, using a stratified multistage sampling method. Experienced nurses, trained in the CareTrack Aged methods ('surveyors'), will review care records of recruited residents within a 1-month period in 2019 and 2020, and assess the care documented against the indicators of appropriate care. Surveyors will concurrently assess residents' QoL using validated questionnaires. ETHICS AND DISSEMINATION: The study has been reviewed and approved by the Human Research Ethics Committee of Macquarie University (5201800386). The research findings will be published in international and national journals and disseminated through conferences and presentations to interested stakeholder groups, including consumers, national agencies, healthcare professionals, policymakers and researchers.

OBJECTIVES: To understand the recent rise in facility deliveries in Ethiopia. DESIGN: A qualitative study. SETTING: Four rural communities in two regions of Ethiopia. PARTICIPANTS: 12 narrative, 12 in-depth interviews and four focus group discussions with recently delivered women; and four focus group discussions with each of grandmothers, fathers and community health workers. RESULTS: We found that several interwoven factors led to the increase in facility deliveries, and that respondents reported that the importance of these factors varied over time. The initial catalysts were a saturation of messages around facility delivery, improved accessibility of facilities, the prohibition of traditional birth attendants, and elders having less influence on deciding the place of delivery. Once women started to deliver in facilities, the drivers of the behaviour changed as women had positive experiences. As more women began delivering in facilities, families shared positive experiences of the facilities, leading to others deciding to deliver in a facility. CONCLUSION: Our findings highlight the need to employ strategies that act at multiple levels, and that both push and pull families to health facilities.

INTRODUCTION: Adolescence is a time of significant physical and emotional change, and there is emerging concern that adolescents living in low- and middle-income countries (LMIC) may face substantial challenges in relation to linear growth and mental health. Data on the global burden of stunting after 5 years of age are limited, but estimates suggest up to 50 per cent of all adolescents in some LMIC are stunted. Additionally, many LMIC lack robust mental health care delivery systems. Pakistan has one of the world's largest populations of adolescents (10 to 19 years) at approximately 40 million. The Nash-wo-Numa study's primary objective is to assess the prevalence and risk factors for stunting among early adolescents in rural Pakistan. The study also aims to determine the prevalence of poor mental health and identify factors associated with common mental health concerns during the childhood to adulthood transition. METHODS: This cross-sectional study will include girls (n= 738) 9.0 to 14.9 years of age and boys (n=687) 10.0 to 15.9 years of age who live in the rural district of Matiari, Pakistan. Participants will be assessed for anthropometrical measures, puberty development, nutritional biomarkers as well as symptoms of depression, anxiety and trauma using validated scales.

OBJECTIVES: To determine whether ETS-related gene (ERG) expression can be used as a biomarker to predict biochemical recurrence and prostate cancer-specific death in patients with high Gleason grade prostate cancer treated with androgen deprivation therapy (ADT) as monotherapy. METHODS: A multicentre retrospective cohort study identifying 149 patients treated with primary ADT for metastatic or non-metastatic prostate cancer with Gleason score 8-10 between 1999 and 2006. Patients planned for adjuvant radiotherapy at diagnosis were excluded. Age at diagnosis, ethnicity, prostate-specific antigen and Charlson-comorbidity score were recorded. Prostatic tissue acquired at biopsy or transurethral resection surgery was assessed for immunohistochemical expression of ERG. Failure of ADT defined as prostate specific antigen nadir +2. Vital status and death certification data determined using the UK National Cancer Registry. Primary outcome measures were overall survival (OS) and prostate cancer specific survival (CSS). Secondary outcome was biochemical recurrence-free survival (BRFS). RESULTS: The median OS of our cohort was 60.2 months (CI 52.0 to 68.3). ERG expression observed in 51/149 cases (34%). Multivariate Cox proportional hazards analysis showed no significant association between ERG expression and OS (p=0.41), CSS (p=0.92) and BRFS (p=0.31). Cox regression analysis showed Gleason score (p=0.003) and metastatic status (p<1×10-5) to be the only significant predictors of prostate CSS. CONCLUSIONS: No significant association was found between ERG status and any of our outcome measures. Despite a limited sample size, our results suggest that ERG does not appear to be a useful biomarker in predicting response to ADT in patients with high risk prostate cancer.

INTRODUCTION: Teledermatology has emerged as an important strategy to enhance access to high-quality skin care. VA Telederm is a provider-facing, web-based mobile app designed to integrate into the existing teledermatology workflow in the US Veterans Health Administration (VHA). In this study, we will conduct a systematic evaluation of VA Telederm on access outcomes in VHA facilities using a pragmatic trial guided by clinical and operational leaders. METHODS AND ANALYSIS: The study is a prospective, stepped-wedge cluster randomised trial with cross-sectional exposure and outcome measurement via retrospective database analysis of administrative records. Each cluster is a VHA facility deemed eligible for the trial. We assign the intervention using a cluster-level balanced randomisation scheme based on facility size, baseline teledermatology uptake and geographic location. The trial will test whether patients receiving dermatological care at participating facilities will have better access compared with patients receiving care through the current standard process. The primary outcomes proxy for patient-level access to dermatology services, including (1) consult completion time for teledermatology consults; (2) appointment completion time for new dermatology consults; and (3) travel distance for dermatology services. As secondary outcomes, we will assess facility-level adoption outcomes, that is, the number of dermatology encounters and the proportion of teledermatology consults out of all dermatology encounters. To account for secular trends in outcomes and for correlation across individuals within clusters, we will assess the impact of the intervention using generalised linear mixed regression models. DISCUSSION: Streamlining the current practice for store-and-forward teledermatology in the VHA can improve access to expert dermatological care for US veterans. The lessons learnt in this trial could validate the use of mobile technology for consultative store-and-forward dermatology in a large healthcare organisation. The results may also be of interest to other medical specialties assessing the merits of implementing mobile telehealth. PROTOCOL VERSION: Version 3; 7 November 2018.

INTRODUCTION: Oral mucositis is an iatrogenic condition of erythematous inflammatory changes which tends to occur on buccal and labial surfaces, the ventral surface of the tongue, the floor of the mouth and the soft palate of patients receiving chemotherapy. This protocol of ongoing randomised parallel group clinical trial aims to access the therapeutic effect of an herbal gel containing 2.5% Arrabidaea chica Verlot standardised extract on oral mucositis in patients with head and neck cancer compared with low-level laser therapy. METHODS AND ANALYSIS: Patients with head and neck cancer held at Clinics Hospital of University of Campinas, Sao Paulo, who develop early signs/symptoms of oral mucositis are eligible. Baseline characteristics of participants include oral mucositis grade and quality of life assessments. Enrolment started in November 2017 with allocation of patients to one of the study groups by means of randomisation. Patients will be treated either with Arrabidaea chica or laser until wound healing. Monitoring includes daily assessment of mucositis grade and diameter measurement by photographs and millimetre periodontal probe. Treatments will be concluded once mucositis is healed. A blinded assessor will evaluate mucositis cure after referred by the study team. At this point, the gel tube will be weighed to indirectly assess patient's compliance. At close-out, data will be analysed by a blinded researcher following the procedures described in the statistical analyses. ETHICS AND DISSEMINATION: This clinical trial was approved by the ethics committee of research in humans at the Faculty of Medical Sciences of University of Campinas (report no. 1,613,563/2016). Results from this trial will be communicated in peer-reviewed publications and scientific presentations. TRIAL REGISTRATION NUMBER: RBR-5×4397.

OBJECTIVES: To explore the pharmaceutical care needs of, and service provision to, older people with sensory impairment (visual, hearing and dual impairment) on prescribed polypharmacy (≥4 medicines) in Scotland. DESIGN: Interviews were conducted with older people with sensory impairment and community pharmacy personnel, which informed the content of a subsequent national cross-sectional survey of community pharmacists. SETTING: Scotland, 2015-2016. PARTICIPANTS: Older people with sensory impairment and community pharmacy personnel. RESULTS: Interviews were completed with 23 older people with sensory impairment (dual impairment n=13, visual or hearing impairment n=5 of each) and 30 community pharmacy personnel from eight of 14 Scottish Health Boards. A total of 171 survey responses were received.Older people reported that they did not always disclose their sensory impairment to pharmacy personnel. They also reported that medicines were difficult to identify particularly when their name, shape or colour changed. Pharmacy personnel relied on visible cues such as white canes or guide dogs to identify visual impairment and suggested that hearing loss was less visible and more difficult to identify. Many assistive aids in support of medicine management, such as dosette boxes, seemed inadequate for complex medication regimens. Few community pharmacy personnel reported receiving training in the care of people with sensory impairment. CONCLUSIONS: This is the first comprehensive, multistakeholder, in-depth exploration of the pharmaceutical care needs of older people with sensory impairment. Strategies are needed to enable people with sensory impairment to disclose their impairment to pharmacy personnel (and other healthcare providers). Community pharmacy personnel require training to deliver person-centred pharmaceutical care for older people with sensory impairment particularly regarding communication with individuals in this vulnerable population.

OBJECTIVE: Evaluate the feasibility and acceptability of routine aspirin in low-risk women, compared with screening-test indicated aspirin for the prevention of pre-eclampsia and fetal growth restriction. DESIGN: Multicentre open-label feasibility randomised controlled trial. SETTING: Two tertiary maternity hospitals in Dublin, Ireland. PARTICIPANTS: 546 low-risk nulliparous women completed the study. INTERVENTIONS: Women underwent computerised randomisation to: Group 1-routine aspirin 75 mg from 11 until 36 weeks; Group 2-no aspirin and; Group 3-aspirin based on the Fetal Medicine Foundation screening test. PRIMARY AND SECONDARY OUTCOME MEASURES: (1) Proportion agreeing to participate; (2) compliance with protocol; (3) proportion where first trimester uterine artery Doppler was obtainable and; (4) time taken to issue a screening result. Secondary outcomes included rates of pre-eclampsia and small-for-gestational-age fetuses. RESULTS: 546 were included in the routine aspirin (n=179), no aspirin (n=183) and screen and treat (n=184) groups. 546 of 1054 were approached (51.8%) and enrolled. Average aspirin adherence was 90%. The uterine artery Doppler was obtained in 98.4% (181/184) and the average time to obtain a screening result was 7.6 (0-26) days. Of those taking aspirin, vaginal spotting was greater; n=29 (15.1%), non-aspirin n=28 (7.9%), OR 2.1 (95% CI 1.2 to 3.6). Postpartum haemorrhage >500 mL was also greater; aspirin n=26 (13.5%), no aspirin n=20 (5.6%), OR 2.6 (95% CI 1.4 to 4.8). CONCLUSION: Low-risk nulliparous women are open to taking aspirin in pregnancy and had high levels of adherence. Aspirin use was associated with greater rates of vaginal bleeding. An appropriately powered randomised controlled trial is now required to address the efficacy and safety of universal low-dose aspirin in low-risk pregnancy compared with a screening approach.

OBJECTIVE: Changing patient demographics make it ever more challenging to maintain the quality and safety of care. One approach to addressing this is the development of training for generalist doctors who can take a more holistic approach to care. The purpose of the work we report here is to consider whether a broad-based training programme prepares doctors for a changing health service. SETTING AND PARTICIPANTS: We adopted a longitudinal, mixed-methods approach, collecting questionnaire data from trainees on the broad-based training (BBT) programme in England (baseline n=62) and comparator trainees in the same regions (baseline n=90). We held 15 focus groups with BBT trainees and one-to-one telephone interviews with trainees post-BBT (n=21) and their Educational Supervisors (n=9). RESULTS: From questionnaire data, compared with comparator groups, BBT trainees were significantly more confident that their training would result in: wider perspectives, understanding specialty complementarity, ability to apply learning across specialties, manage complex patients and provide patient-focused care. Data from interviews and focus groups provided evidence of positive consequences for patient care from BBT trainees' ability to apply knowledge from other specialties. Specifically, insights from BBT enabled trainees to tailor referrals and consider patients' psychological as well as physical needs, thus adopting a more holistic approach to care. Unintended consequences were revealed in focus groups where BBT trainees expressed feelings of isolation. However, when we explored this sentiment on questionnaire surveys, we found that at least as many in the comparator groups sometimes felt isolated. CONCLUSIONS: Practitioners with an understanding of care across specialty boundaries can enhance patient care and reduce risks from poor inter-specialty communication. Internationally, there is growing recognition of the place of generalism in medical practice and the need to take a more person-centred approach. Broad-based approaches to training support the development of generalist doctors, which is well-suited to a changing health service.

OBJECTIVES: Pseudomonas aeruginosa (P. aeruginosa) occupies an important niche in the pathogenic microbiome of bronchiectasis. The objective of this study is to evaluate the clinical characteristics and prognostic value of P. aeruginosa in Chinese adult patients with bronchiectasis. METHODS: This retrospective and follow-up study enrolled 1188 patients diagnosed with bronchiectasis at Shanghai Pulmonary Hospital between January 2011 and December 2012. The patients' clinical data including anthropometry, clinical symptoms, serum biomarkers, radiographic manifestations and lung function indices were reviewed. The median follow-up duration (IQR) was 44 (40-54) months, during which 289 patients were lost to follow-up. Data from 899 patients were collected and analysed for the outcomes of mortality, annual exacerbation frequency and health-related quality of life. RESULTS: P. aeruginosa was isolated from 232 patients, alongside other pathogens such as Aspergillus (n=75) and Candida albicans (n=72). There were 74 deaths (12% of patients with P. aeruginosa, 7.3% of those without) over the course of the follow-up. The isolation of P. aeruginosa was a risk factor for all-cause mortality (HR, 3.07; 95% CI 1.32 to 7.15) and was associated with high rates of exacerbations (ie, ≥3 exacerbations per year of follow-up) (HR, 2.40; 95% CI 1.20 to 4.79). Patients with P. aeruginosa also had worse scores on the Hospital Anxiety and Depression Scale (anxiety, p=0.005; depression, p<0.001), the Leicester Cough Questionnaire (p=0.033) and the modified Medical Research Council scale (p=0.001) compared with those without P. aeruginosa. CONCLUSIONS: Isolation of P. aeruginosa in patients with bronchiectasis is a significant prognostic indicator and should be a major factor in the clinical management of the disease.

INTRODUCTION: National guidelines recommend that all reproductive-age women with cancer be informed of their fertility risks and offered referral to fertility specialists to discuss fertility preservation options. However, reports indicate that only 5% of patients have consultations, and rates of long-term infertility-related distress remain high. Previous studies report several barriers to fertility preservation; however, initial success has been reported using provider education, patient decision aids and navigation support. This protocol will test effects of a multicomponent intervention compared with usual care on women's fertility preservation knowledge and decision-making outcomes. METHODS AND ANALYSIS: This cluster-randomised trial will compare the multicomponent intervention (provider education, patient decision aid and navigation support) with usual care (consultation and referral, if requested). One hundred newly diagnosed English-speaking women of reproductive age who are at risk of cancer-related infertility will be recruited from four regional oncology clinics.The Pathways patient decision aid website provides (1) up-to-date evidence and descriptions of fertility preservation and other family-building options, tailored to cancer type; (2) structured guidance to support personalising the information and informed decision-making; and (3) a printable summary to help women prepare for discussions with their oncologist and/or fertility specialist. Four sites will be randomly assigned to intervention or control groups. Participants will be recruited after their oncology consultation and asked to complete online questionnaires at baseline, 1 week and 2 months to assess their demographics, fertility preservation knowledge, and decision-making process and quality. The primary outcome (decisional conflict) will be tested using Fisher's exact test. Secondary outcomes will be assessed using generalised linear mixed models, and sensitivity analyses will be conducted, as appropriate. ETHICS AND DISSEMINATION: The University of Texas MD Anderson Cancer Center provided approval and ongoing review of this protocol. Results will be presented at relevant scientific meetings and submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT03141437; Pre-results.

INTRODUCTION: Despite widespread availability of clinical practice guidelines (CPGs), considerable gaps continue between the care that is recommended ('appropriate care') and the care provided. Problems with current CPGs are commonly cited as barriers to providing 'appropriate care'.Our study aims to develop and test an alternative method to keep CPGs accessible and up to date. This method aims to mitigate existing problems by using a single process to develop clinical standards (embodied in clinical indicators) collaboratively with researchers, healthcare professionals, patients and consumers. A transparent and inclusive online curated (purpose-designed, custom-built, wiki-type) system will use an ongoing and iterative documentation process to facilitate synthesis of up-to-date information and make available its provenance. All participants are required to declare conflicts of interest. This protocol describes three phases: engagement of relevant stakeholders; design of a process to develop clinical standards (embodied in indicators) for 'appropriate care' for common medical conditions; and evaluation of our processes, products and feasibility. METHODS AND ANALYSIS: A modified e-Delphi process will be used to gain consensus on 'appropriate care' for a range of common medical conditions. Clinical standards and indicators will be developed through searches of national and international guidelines, and formulated with explicit criteria for inclusion, exclusion, time frame and setting. Healthcare professionals and consumers will review the indicators via the wiki-based modified e-Delphi process. Reviewers will declare conflicts of interest which will be recorded and managed according to an established protocol. The provenance of all indicators and suggestions included or excluded will be logged from indicator inception to finalisation. A mixed-methods formative evaluation of our research methodology will be undertaken. ETHICS AND DISSEMINATION: Human Research Ethics Committee approval has been received from the University of South Australia. We will submit the results of the study to relevant journals and offer national and international presentations.

OBJECTIVES: Treatment failure and poor 5-year survival in mucosal head and neck squamous cell carcinoma (HNSCC) has remained unchanged for decades mainly due to advanced stage of presentation and high rates of recurrence. Incomplete surgical removal of the tumour, attributed to lack of reliable methods to delineate the surgical margins, is a major cause of disease recurrence. The predictability of recurrence using immunohistochemistry (IHC) to delineate surgical margins (PRISM) in mucosal HNSCC study aims to redefine margin status by identifying the true extent of the tumour at the molecular level by performing IHC with molecular markers, eukaryotic initiation factor, eIF4Eand tumour suppressor gene, p53, on the surgical margins and test the use of Lugol's iodine and fluorescence visualisation prior to the wide local excision. This article describes the study protocol at its pre - results stage. METHODS AND ANALYSIS: PRISM-HNSCC is a bilateral observational research being conducted in Darwin, Australia and Vellore, India. Individuals diagnosed with HNSCC will undergo the routine wide local excision of the tumour followed by histopathological assessment. Tumours with clear surgical margins that satisfy the exclusion criteria will be selected for further staining of the margins with eIF4E and p53 antibodies. Results of IHC staining will be correlated with recurrences in an attempt to predict the risk of disease recurrence. Patients in Darwin will undergo intraoperative staining of the lesion with Lugol's iodine and fluorescence visualisation to delineate the excision margins while patients in Vellore will not undertake these tests. The outcomes will be analysed. ETHICS AND DISSEMINATION: The PRISM-HNSCC study was approved by the institutional ethics committees in Darwin (Human Research Ethics Committee 13-2036) and Vellore (Institutional Review Board Min. no. 8967). Outcomes will be disseminated through publications in academic journals and presentations at educational meetings and conferences. It will be presented as dissertation at the Charles Darwin University. We will communicate the study results to both participating sites. Participating sites will communicate results with patients who have indicated an interest in knowing the results.

OBJECTIVES: When monitoring patients over time, clinicians may struggle to distinguish 'real changes' in consecutive blood parameters from so-called natural fluctuations. In practice, they have to do so by relying on their clinical experience and intuition. We developed Labtracker+, a medical app that calculates the probability that an increase or decrease over time in a specific blood parameter is real, given the time between measurements. DESIGN: We presented patient cases to 135 participants to examine whether there is a difference between medical students, residents and experienced clinicians when it comes to interpreting changes between consecutive laboratory results. Participants were asked to interpret if changes in consecutive laboratory values were likely to be 'real' or rather due to natural fluctuations. The answers of the study participants were compared with the calculated probabilities by the app Labtracker+ and the concordance rates were assessed. SETTING AND PARTICIPANTS: Medical students (n=92), medical residents from the department of internal medicine (n=19) and internists (n=24) at a Dutch University Medical Centre. PRIMARY AND SECONDARY OUTCOME MEASURES: Concordance rates between the study participants and the calculated probabilities by the app Labtracker+ were compared. Besides, we tested whether physicians with clinical experience scored better concordance rates with the app Labtracker+ than inexperienced clinicians. RESULTS: Medical residents and internists showed significantly better concordance rates with the calculated probabilities by the app Labtracker+ than medical students, regarding their interpretation of differences between consecutive laboratory results (p=0.009 and p<0.001, respectively). CONCLUSION: The app Labtracker+ could serve as a clinical decision tool in the interpretation of consecutive laboratory test results and could contribute to rapid recognition of parameter changes by physicians.

BACKGROUND: The integration of digital technology into everyday lives of young people has become widespread. It is not known whether and how technology influences barriers and facilitators to healthcare, and whether and how young people navigate between face-to-face and virtual healthcare. To provide new knowledge essential to policy and practice, we designed a study that would explore health system access and navigation in the digital age. The study objectives are to: (1) describe experiences of young people accessing and navigating the health system in New South Wales (NSW), Australia; (2) identify barriers and facilitators to healthcare for young people and how these vary between groups; (3) describe health system inefficiencies, particularly for young people who are marginalised; (4) provide policy-relevant knowledge translation of the research data. METHODS AND ANALYSIS: This mixed methods study has four parts, including: (1) a cross-sectional survey of young people (12-24 years) residing in NSW, Australia; (2) a longitudinal, qualitative study of a subsample of marginalised young people (defined as young people who: identify as Aboriginal and/or Torres Strait Islander; are experiencing homelessness; identify as sexuality and/or gender diverse; are of refugee or vulnerable migrant background; and/or live in rural or remote NSW); (3) interviews with professionals; (4) a knowledge translation forum. ETHICS AND DISSEMINATION: Ethics approvals were sought and granted. Data collection commenced in March 2016 and will continue until June 2017. This study will gather practice and policy-relevant intelligence about contemporary experiences of young people and health services, with a unique focus on five different groups of marginalised young people, documenting their experiences over time. Access 3 will explore navigation around all levels of the health system, determine whether digital technology is integrated into this, and if so how, and will translate findings into policy-relevant recommendations.

OBJECTIVES: Drowning in children under the age of 5 is a frequently occurring, yet preventable event. This research used behavioural theory to test the suitability and appropriateness of a drowning prevention message in a community service video. DESIGN: This qualitative study used content analysis of focus groups. Constructs from the Health Belief Model guided the data analysis. SETTING: Community organisations and playgrounds in Perth, Western Australia. PARTICIPANTS: Participants were parents or carers of at least one child under 5 years residing in Western Australia. Seven focus groups (n=57) were conducted with eight participants in each group. Most participants were parents (96%), female (95%), aged between 25 and 34 years (63%) and were born in Australia (68%). RESULTS: Participants indicated the community service video was credible in communicating the message that young children were susceptible to drowning in shallow water and that various water hazards existed in and around the home. However, a range of external factors, such as the child's age, type of water hazard, presence of siblings and other environmental factors, influenced risk perceptions. Child drowning was seen as a serious issue. Controlling access to water and the role of supervision were understood to be important factors in preventing drowning. CONCLUSIONS: The lack of published drowning prevention interventions shaped by behavioural theory limits the understanding of best practice. Using constructs from the Health Belief Model, this research confirmed the perceived seriousness, devastating and unforgettable consequence of drowning; however, findings were mixed regarding cues to action. Future development of drowning prevention media messages should test strategies to increase susceptibility and self-efficacy among the target group and explore the impact of different message senders. The findings provide a valuable understanding of possible messages and their execution for use in media campaigns, as one component of an effective public health intervention to prevent child drowning underpinned by behavioural theory.

OBJECTIVES: Overcrowding in the emergency department (ED) is common in the UK as in other countries worldwide. Computer simulation is one approach used for understanding the causes of ED overcrowding and assessing the likely impact of changes to the delivery of emergency care. However, little is known about the usefulness of computer simulation for analysis of ED patient flow. We undertook a systematic review to investigate the different computer simulation methods and their contribution for analysis of patient flow within EDs in the UK. METHODS: We searched eight bibliographic databases (MEDLINE, EMBASE, COCHRANE, WEB OF SCIENCE, CINAHL, INSPEC, MATHSCINET and ACM DIGITAL LIBRARY) from date of inception until 31 March 2016. Studies were included if they used a computer simulation method to capture patient progression within the ED of an established UK National Health Service hospital. Studies were summarised in terms of simulation method, key assumptions, input and output data, conclusions drawn and implementation of results. RESULTS: Twenty-one studies met the inclusion criteria. Of these, 19 used discrete event simulation and 2 used system dynamics models. The purpose of many of these studies (n=16; 76%) centred on service redesign. Seven studies (33%) provided no details about the ED being investigated. Most studies (n=18; 86%) used specific hospital models of ED patient flow. Overall, the reporting of underlying modelling assumptions was poor. Nineteen studies (90%) considered patient waiting or throughput times as the key outcome measure. Twelve studies (57%) reported some involvement of stakeholders in the simulation study. However, only three studies (14%) reported on the implementation of changes supported by the simulation. CONCLUSIONS: We found that computer simulation can provide a means to pretest changes to ED care delivery before implementation in a safe and efficient manner. However, the evidence base is small and poorly developed. There are some methodological, data, stakeholder, implementation and reporting issues, which must be addressed by future studies.

OBJECTIVES: To determine the association between Toxoplasma gondii infection and Parkinson's disease and to investigate whether T. gondii seropositivity is associated with the general characteristics of patients with Parkinson's disease. DESIGN: Case-control study. SETTING: Cases and controls were enrolled in Durango City, Mexico. PARTICIPANTS: 65 patients with Parkinson's disease and 195 age- and gender-matched control subjects without Parkinson's disease. PRIMARY AND SECONDARY OUTCOME MEASURES: Serum samples of participants were analysed for anti-T. gondii IgG and IgM antibodies by commercially available enzyme-linked immunoassays. Prevalence of T. gondii DNA was determined in seropositive subjects using PCR. The association between clinical data and infection was examined by bivariate analysis. RESULTS: Anti-T. gondii IgG antibodies were found in 6/65 cases (9.2%) and in 21/195 controls (10.8%) (OR 0.84; 95% CI 0.32 to 2.18; p=0.81). The frequency of high (>150 IU/mL) antibody levels was similar among cases and controls (p=0.34). None of the anti-T. gondii IgG positive cases and four of the anti-T. gondii IgG positive controls had anti-T. gondii IgM antibodies (p=0.54). The prevalence of T. gondii DNA was comparable in seropositive cases and controls (16.7% and 25%, respectively; p=1.0). Seroprevalence of T. gondii infection was associated with a young age onset of disease (p=0.03), high Unified Parkinson Disease Rating Scale scores (p=0.04) and depression (p=0.02). Seropositivity to T. gondii infection was lower in patients treated with pramipexole than in patients without this treatment (p=0.01). However, none of the associations remained significant after Bonferroni correction. CONCLUSIONS: The results do not support an association between T. gondii infection and Parkinson's disease. However, T. gondii infection might have an influence on certain symptoms of Parkinson's disease. Further research to elucidate the role of T. gondii exposure on Parkinson's disease is warranted.
