Association between deep learning measured retinal vessel calibre and incident myocardial infarction in a retrospective cohort from the UK Biobank

Por: Wong · Y. L. · Yu · M. · Chong · C. · Yang · D. · Xu · D. · Lee · M. L. · Hsu · W. · Wong · T. Y. · Cheng · C. · Cheung · C. Y.
Background

Cardiovascular disease is a leading cause of global death. Prospective population-based studies have found that changes in retinal microvasculature are associated with the development of coronary artery disease. Recently, artificial intelligence deep learning (DL) algorithms have been developed for the fully automated assessment of retinal vessel calibres.

Methods

In this study, we validate the association between retinal vessel calibres measured by a DL system (Singapore I Vessel Assessment) and incident myocardial infarction (MI) and assess its incremental performance in discriminating patients with and without MI when added to risk prediction models, using a large UK Biobank cohort.

Results

Retinal arteriolar narrowing was significantly associated with incident MI in both the age, gender and fellow calibre-adjusted (HR=1.67 (95% CI: 1.19 to 2.36)) and multivariable models (HR=1.64 (95% CI: 1.16 to 2.32)) adjusted for age, gender and other cardiovascular risk factors such as blood pressure, diabetes mellitus (DM) and cholesterol status. The area under the receiver operating characteristic curve increased from 0.738 to 0.745 (p=0.018) in the age–gender-adjusted model and from 0.782 to 0.787 (p=0.010) in the multivariable model. The continuous net reclassification improvements (NRIs) were significant in the age and gender-adjusted (NRI=21.56 (95% CI: 3.33 to 33.42)) and the multivariable models (NRI=18.35 (95% CI: 6.27 to 32.61)). In the subgroup analysis, similar associations between retinal arteriolar narrowing and incident MI were observed, particularly for men (HR=1.62 (95% CI: 1.07 to 2.46)), non-smokers (HR=1.65 (95% CI: 1.13 to 2.42)), patients without DM (HR=1.73 (95% CI: 1.19 to 2.51)) and hypertensive patients (HR=1.95 (95% CI: 1.30 to 2.93)) in the multivariable models.

Conclusion

Our results support DL-based retinal vessel measurements as markers of incident MI in a predominantly Caucasian population.

Evidence for clinician underprescription of and patient non-adherence to guideline-recommended cardiovascular medications among adults with peripheral artery disease: protocol for a systematic review and meta-analysis

Por: de Launay · D. · Paquet · M. · Kirkham · A. M. · Graham · I. D. · Fergusson · D. A. · Nagpal · S. K. · Shorr · R. · Grimshaw · J. M. · Roberts · D. J.
Introduction

International guidelines recommend that adults with peripheral artery disease (PAD) be prescribed antiplatelet, statin and antihypertensive medications. However, it is unclear how often people with PAD are underprescribed these drugs, which characteristics predict clinician underprescription of and patient non-adherence to guideline-recommended cardiovascular medications, and whether underprescription and non-adherence are associated with adverse health and health system outcomes.

Methods and analysis

We will search MEDLINE, EMBASE and Evidence-Based Medicine Reviews from 2006 onwards. Two investigators will independently review abstracts and full-text studies. We will include studies that enrolled adults and reported the incidence and/or prevalence of clinician underprescription of or patient non-adherence to guideline-recommended cardiovascular medications among people with PAD; adjusted risk factors for underprescription of/non-adherence to these medications; and adjusted associations between underprescription/non-adherence to these medications and outcomes. Outcomes will include mortality, major adverse cardiac and limb events (including revascularisation procedures and amputations), other reported morbidities, healthcare resource use and costs. Two investigators will independently extract data and evaluate study risk of bias. We will calculate summary estimates of the incidence and prevalence of clinician underprescription/patient non-adherence across studies. We will also conduct subgroup meta-analyses and meta-regression to determine if estimates vary by country, characteristics of the patients and treating clinicians, population-based versus non-population-based design, and study risks of bias. Finally, we will calculate pooled adjusted risk factors for underprescription/non-adherence and adjusted associations between underprescription/non-adherence and outcomes. We will use Grading of Recommendations, Assessment, Development and Evaluation to determine estimate certainty.

Ethics and dissemination

Ethics approval is not required as we are studying published data. This systematic review will synthesise existing evidence regarding clinician underprescription of and patient non-adherence to guideline-recommended cardiovascular medications in adults with PAD. Results will be used to identify evidence-care gaps and inform where interventions may be required to improve clinician prescribing and patient adherence to prescribed medications.

Pancreatic quantitative sensory testing to predict treatment response of endoscopic therapy or surgery for painful chronic pancreatitis with pancreatic duct obstruction: study protocol for an observational clinical trial

Por: Phillips · A. E. · Afghani · E. · Akshintala · V. S. · Benos · P. Y. · Das · R. · Drewes · A. M. · Easler · J. · Faghih · M. · Gabbert · C. · Halappa · V. · Khashab · M. A. · Olesen · S. S. · Saloman · J. L. · Sholosh · B. · Slivka · A. · Wang · T. · Yadav · D. · Singh · V. K.
Introduction

Treatment for abdominal pain in patients with chronic pancreatitis (CP) remains challenging in the setting of central nervous system sensitisation, a phenomenon of remodelling and neuronal hyperexcitability resulting from persistent pain stimuli. This is suspected to render affected individuals less likely to respond to conventional therapies. Endotherapy or surgical decompression is offered to patients with pancreatic duct obstruction. However, the response to treatment is unpredictable. Pancreatic quantitative sensory testing (P-QST), an investigative technique of standardised stimulations to test the pain system in CP, has been used for phenotyping patients into three mutually exclusive groups: no central sensitisation, segmental sensitisation (pancreatic viscerotome) and widespread hyperalgesia suggestive of supraspinal central sensitisation. We will test the predictive capability of the pretreatment P-QST phenotype to predict the likelihood of pain improvement following invasive treatment for painful CP.

Methods and analysis

This observational clinical trial will enrol 150 patients from the University of Pittsburgh, Johns Hopkins and Indiana University. Participants will undergo pretreatment phenotyping with P-QST. Treatment will be pancreatic endotherapy or surgery for clearance of painful pancreatic duct obstruction. Primary outcome: average pain score over the preceding 7 days measured by Numeric Rating Scale at 6 months postintervention. Secondary outcomes will include changes in opioid use during follow-up, and patient-reported outcomes in pain and quality of life at 3, 6 and 12 months after the intervention. Exploratory outcomes will include creation of a model for individualised prediction of response to invasive treatment.

Ethics and dissemination

The trial will evaluate the ability of P-QST to predict response to invasive treatment for painful CP and develop a predictive model for individualised prediction of treatment response for widespread use. This trial was approved by the University of Pittsburgh Institutional Review Board. Data and results will be reported and disseminated in conjunction with National Institutes of Health policies.

Background

Patient engagement is the active collaboration between patient partners and health system partners towards a goal of making decisions that centre patient needs—thus improving experiences of care, and overall effectiveness of health services in alignment with the Quintuple Aim. An important but challenging aspect of patient engagement is including diverse perspectives particularly those experiencing health inequities. When such populations are excluded from decision-making in health policy, practice and research, we risk creating a healthcare ecosystem that reinforces structural marginalisation and perpetuates health inequities.

Approach

Despite the growing body of literature on knowledge coproduction, few have addressed the role of power relations in patient engagement and offered actionable steps for engaging diverse patients in an inclusive way with a goal of improving health equity. To fill this knowledge gap, we draw on theoretical concepts of power, our own experience codesigning a novel model of patient engagement that is equity promoting, Equity Mobilizing Partnerships in Community, and extensive experience as patient partners engaged across the healthcare ecosystem. We introduce readers to a new conceptual tool, the Power Wheel, that can be used to analyse the interspersion of power in the places and spaces of patient engagement.

Conclusion

As a tool for ongoing praxis (reflection +action), the Power Wheel can be used to report, reflect and resolve power asymmetries in patient-partnered projects, thereby increasing transparency and illuminating opportunities for equitable transformation and social inclusion so that health services can meet the needs and priorities of all people.

Comprehensive quality assessment for aphasia rehabilitation after stroke: protocol for a multicentre, mixed-methods study

Por: Harvey · S. · Stone · M. · Zingelman · S. · Copland · D. A. · Kilkenny · M. F. · Godecke · E. · Cadilhac · D. A. · Kim · J. · Olaiya · M. T. · Rose · M. L. · Breitenstein · C. · Shrubsole · K. · OHalloran · R. · Hill · A. J. · Hersh · D. · Mainstone · K. · Mainstone · P. · Unsworth · C. A
Introduction

People with aphasia following stroke experience disproportionally poor outcomes, yet there is no comprehensive approach to measuring the quality of aphasia services. The Meaningful Evaluation of Aphasia SeRvicES (MEASuRES) minimum dataset was developed in partnership with people with lived experience of aphasia, clinicians and researchers to address this gap. It comprises sociodemographic characteristics, quality indicators, treatment descriptors and outcome measurement instruments. We present a protocol to pilot the MEASuRES minimum dataset in clinical practice, describe the factors that hinder or support implementation and determine meaningful thresholds of clinical change for core outcome measurement instruments.

Methods and analysis

This research aims to deliver a comprehensive quality assessment toolkit for poststroke aphasia services in four studies. A multicentre pilot study (study 1) will test the administration of the MEASuRES minimum dataset within five Australian health services. An embedded mixed-methods process evaluation (study 2) will evaluate the performance of the minimum dataset and explore its clinical applicability. A consensus study (study 3) will establish consumer-informed thresholds of meaningful change on core aphasia outcome constructs, which will then be used to establish minimal important change values for corresponding core outcome measurement instruments (study 4).

Ethics and dissemination

Studies 1 and 2 have been registered with the Australian and New Zealand Clinical Trial Registry (ACTRN12623001313628). Ethics approval has been obtained from the Royal Brisbane and Women’s Hospital (HREC/2023/MNHB/95293) and The University of Queensland (2022/HE001946 and 2023/HE001175). Study findings will be disseminated through peer-reviewed publications, conference presentations and engagement with relevant stakeholders including healthcare providers, policy-makers, stroke and rehabilitation audit and clinical quality registry custodians, consumer support organisations, and individuals with aphasia and their families.

Work environment and hypertension in industrial settings in Benin in 2019: a cross-sectional study

Por: Adjobimey · M. · Houehanou · C. Y. · Cisse · I. M. · Mikponhoue · R. · Hountohotegbe · E. · Tchibozo · C. · Adjogou · A. · Dossougbete · V. · Gounongbe · F. · Ayelo · P. A. · Hinson · V. · Houinato · D. S.
Objective

To determine the association between occupational factors, particularly psychosocial factors, and hypertension.

Design

Descriptive and analytical cross-sectional study using logistic multivariate regression.

Setting

Fifteen cotton ginning plants in Benin.

Participants

Permanent and occasional workers in the cotton ginning industry.

Data collection

Data on sociodemographic, occupational, behavioural and clinical history characteristics were collected using a number of standardised, interviewer-administered questionnaires. These questionnaires were based on the WHO’s non-communicable disease questionnaire, Karasek questionnaire and Siegrist questionnaire. Weight, height and blood pressure were measured. Any worker with systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg according to the WHO criteria was considered hypertensive, as was any subject on antihypertensive treatment even if blood pressure was normal.

Results

A total of 1883 workers were included, with a male to female ratio of 9.08. Of these, 510 suffered from hypertension (27.1%, 95% CI 25.1 to 29.2). In the multivariate analysis, the risk factors identified were occupational stress (adjusted OR (aOR)=3.96, 95% CI 1.28 to 12.2), age ≥25 years (aOR=2.77, 95% CI 1.55 to 4.96), body mass index of 25–30 kg/m2 (aOR=1.71, 95% CI 1.32 to 2.2), body mass index >30 kg/m2 (aOR=2.74, 95% CI 1.84 to 4.09), permanent worker status (aOR=1.66, 95% CI 1.44 to 2.41) and seniority in the textile sector >5 years (aOR=2.18, 95% CI 1.7 to 2.8). Recognition at work emerged as an effect-modifying factor subject to stratification.

Conclusions

Occupational factors, particularly job strain and recognition at work, are modifiable factors associated with hypertension in the ginning plants sector and deserve to be corrected through occupational health promotion and prevention.

Temporal trends of ambulance time intervals for suspected stroke/transient ischaemic attack (TIA) before and during the COVID-19 pandemic in Ireland: a quasi-experimental study

Por: Burton · E. · Quinn · R. · Crosbie-Staunton · K. · Deasy · C. · Masterson · S. · O'Donnell · C. · Merwick · A. · Willis · D. · Kearney · P. M. · Mc Carthy · V. J. C. · Buckley · C. M.
Objectives

Time is a fundamental component of acute stroke and transient ischaemic attack (TIA) care, thus minimising prehospital delays is a crucial part of the stroke chain of survival. COVID-19 restrictions were introduced in Ireland in response to the pandemic, which resulted in major societal changes. However, current research on the effects of the COVID-19 pandemic on prehospital care for stroke/TIA is limited to early COVID-19 waves. Thus, we aimed to investigate the effect of the COVID-19 pandemic on ambulance time intervals and suspected stroke/TIA call volume for adults with suspected stroke and TIA in Ireland, from 2018 to 2021.

Design

We conducted a secondary data analysis with a quasi-experimental design.

Setting

We used data from the National Ambulance Service in Ireland. We defined the COVID-19 period as ‘1 March 2020–31 December 2021’ and the pre-COVID-19 period ‘1 January 2018–29 February 2020’.

Primary and secondary outcome measures

We compared five ambulance time intervals: ‘allocation performance’, ‘mobilisation performance’, ‘response time’, ‘on scene time’ and ‘conveyance time’ between the two periods using descriptive and regression analyses. We also compared call volume for suspected stroke/TIA between the pre-COVID-19 and COVID-19 periods using interrupted time series analysis.

Participants

We included all suspected stroke/TIA cases ≥18 years who called the National Ambulance Service from 2018 to 2021.

Results

40 004 cases were included: 19 826 in the pre-COVID-19 period and 19 731 in the COVID-19 period. All ambulance time intervals increased during the pandemic period compared with pre-COVID-19 (p

Conclusions

A ’shock' like a pandemic has a negative impact on the prehospital phase of care for time-sensitive conditions like stroke/TIA. System evaluation and public awareness campaigns are required to ensure maintenance of prehospital stroke pathways amidst future healthcare crises. Thus, this research is relevant to routine and extraordinary prehospital service planning.

REST: a preoperative tailored sleep intervention for patients undergoing total knee replacement - feasibility study for a randomised controlled trial

Por: Bertram · W. · Penfold · C. · Glynn · J. · Johnson · E. · Burston · A. · Rayment · D. · Howells · N. · White · S. · Wylde · V. · Gooberman-Hill · R. · Blom · A. · Whale · K.
Objectives

To test the feasibility of a randomised controlled trial (RCT) of a novel preoperative tailored sleep intervention for patients undergoing total knee replacement.

Design

Feasibility two-arm two-centre RCT using 1:1 randomisation with an embedded qualitative study.

Setting

Two National Health Service (NHS) secondary care hospitals in England and Wales.

Participants

Preoperative adult patients identified from total knee replacement waiting lists with disturbed sleep, defined as a score of 0–28 on the Sleep Condition Indicator questionnaire.

Intervention

The REST intervention is a preoperative tailored sleep assessment and behavioural intervention package delivered by an Extended Scope Practitioner (ESP), with a follow-up phone call 4 weeks postintervention. All participants received usual care as provided by the participating NHS hospitals.

Outcome measures

The primary aim was to assess the feasibility of conducting a full trial. Patient-reported outcomes were assessed at baseline, 1-week presurgery, and 3 months postsurgery. Data collected to determine feasibility included the number of eligible patients, recruitment rates and intervention adherence. Qualitative work explored the acceptability of the study processes and intervention delivery through interviews with ESPs and patients.

Results

Screening packs were posted to 378 patients and 57 patients were randomised. Of those randomised, 20 had surgery within the study timelines. An appointment was attended by 25/28 (89%) of participants randomised to the intervention. Follow-up outcomes measures were completed by 40/57 (70%) of participants presurgery and 15/57 (26%) postsurgery. Where outcome measures were completed, data completion rates were 80% or higher for outcomes at all time points, apart from the painDETECT: 86% complete at baseline, 72% at presurgery and 67% postsurgery. Interviews indicated that most participants found the study processes and intervention acceptable.

Conclusions

This feasibility study has demonstrated that with some amendments to processes and design, an RCT to evaluate the clinical and cost-effectiveness of the REST intervention is feasible.

Exploring the barriers to, and importance of, participant diversity in early-phase clinical trials: an interview-based qualitative study of professionals and patient and public representatives

Por: Chatters · R. · Dimairo · M. · Cooper · C. · Ditta · S. · Woodward · J. · Biggs · K. · Ogunleye · D. · Thistlethwaite · F. · Yap · C. · Rothman · A.
Objectives

To explore the importance of, and barriers to achieving, diversity in early-phase clinical trials.

Design

Qualitative interviews analysed using thematic analysis.

Setting and participants

Five professionals (clinical researchers and methodologists) and three patient and public representatives (those with experience of early-phase clinical trials and/or those from ethnic minority backgrounds) were interviewed between June and August 2022. Participants were identified via their institutional web page, existing contacts or social media (eg, X, formerly known as Twitter).

Results

Professionals viewed that diversity is not currently considered in all early-phase clinical trials but felt that it should always be taken into account. Such trials are primarily undertaken at a small number of centres, thus limiting the populations they can access. Referrals from clinicians based in the community may increase diversity; however, those referred are often not from underserved groups. Referrals may be hindered by the extra resources required to approach and recruit underserved groups and participants often having to undertake ‘self-driven’ referrals. Patient and public representatives stated that diversity is important in research staff and that potential participants should be informed of the need for diversity. Those from underserved groups may require clarification regarding the potential harms of a treatment, even if these are unknown. Education may improve awareness and perception of early-phase clinical trials. We provide 14 recommendations to improve diversity in early-phase clinical trials.

Conclusions

Diversity should be considered in all early-phase trials. Consideration is required regarding the extent of diversity and how it is addressed. The increased resources needed to recruit those from underserved groups may warrant funders to increase the funds to support the recruitment of such participants. The potential harms and societal benefits of the research should be presented to potential participants in a balanced but accurate way to increase transparency.

Daily life activities of young adults with obesity living in highly accessible and compact urban environments in Seoul, South Korea: a spatiotemporal qualitative study protocol

Por: Kim · D. H. · Lee · E. H. L. · Jeong · J. Y. · Lee · J. · Yoo · S.
Introduction

Amid the growing global concern about obesity, young adults in South Korea are particularly affected, with 30.8% of people aged 19–34 classified as obese. Given the urban-centric lifestyle of Korean youth, understanding the relationship between daily life activities and the urban environment holds great promise for effective interventions. This study aims to explore the daily life activities of young adults with obesity in Seoul, a city known for its highly accessible and compact environment. The research questions explore the interaction between daily life activities and the neighbourhood environment and consider weight management in an urban context.

Methods and analysis

This study uses an extended qualitative geographic information system approach to explore a district in Seoul with a highly accessible and compact urban environment. The sample comprises young adults with obesity (aged 19–34) residing in the study area, with recruitment targeting up to 51 participants for data saturation. A qualitative, multimethod approach combines descriptive and spatiotemporal data collection. Descriptive data are being collected, including in-depth interviews and photographs of daily food consumption. Spatial data collection involves field observations, cognitive mapping and mobile Global Positioning System tracking. Temporal data is gathered through participants drawing round timetables, detailing their daily schedules. Data analysis will entail thematic analysis of the interview data and content analysis of the spatiotemporal data. For the integrated analysis, pattern finding will be used to synthesise the data.

Ethics and dissemination

This study was approved by the institutional review board of Seoul National University on 11 July 2022. Data collection and curation are currently underway, and the results of the analysis will be shared with the scientific community at international conferences and peer-reviewed journals. We are planning an open seminar to share our research findings with relevant policy-makers, community organisations and health professionals.

REKOVER study protocol: a pRospective patient treatment rEgistry of tramadol and dexKetoprofen trometamol oral fixed-dose combination (SKUDEXA) in mOderate to seVere acutE pain in Real-world setting in Asia

Introduction

Satisfactory management of acute pain remains a major medical challenge despite the availability of multiple therapeutic options including the fixed-dose combination (FDC) drugs. Tramadol and dexketoprofen trometamol (TRAM/DKP) 75/25 mg FDC was launched in 2018 in Asia and is widely used in the management of moderate to severe acute pain. There are limited data on its effectiveness and safety in Asian patients, and therefore, a need to better understand its usage patterns in clinical practice. We aim to understand the usage pattern of TRAM/DKP FDC, its effectiveness and tolerability in patients with moderate to severe acute pain in Asia.

Methods and analysis

REKOVER is a phase-IV, multicountry, multicentre, prospective, real-world observational study. A total of 750 postsurgical and non-surgical patients (male and female, aged 18–80 years) will be recruited from 13 tertiary-care hospitals (15 sites) in Singapore, Thailand, the Philippines and Malaysia. All patients prescribed with TRAM/DKP FDC and willing to participate in the study will be enrolled. The recruitment duration for each site will be 6 months. The severity of pain will be collected using Numeric Pain Rating Scale through the treatment period from day 1 to day 5, while satisfaction with the treatment will be evaluated using Patient Global Evaluation Scale at the end of treatment. Any adverse event reported during the study duration will be recorded for safety analysis (up to day 6). The study data will be entered into the ClaimIt portal and mobile application (app) (ObvioHealth, USA). All the inpatient data will be entered into the portal by the study site and for outpatient it will be done by patients through an app.

Ethics and dissemination

The study has been approved by the local ethics committee from each study sites in Singapore, Thailand, the Philippines and Malaysia. Findings will be disseminated through local and global conference presentations, publications in peer-reviewed scientific journals and continuing medical education.

What Matters to Aboriginal and Torres Strait Islander Youth (WM2Y): a study protocol to develop a national youth well-being measure

Por: Garvey · G. · Howard · K. · Garvey · D. · Dickson · M. · Howell · M. · Butler · T. L. · Cadet-James · Y. · Cunningham · J. · Bainbridge · R. · McGorry · P. · Williamson · A. · Anderson · K. M.
Introduction

Adolescents face challenges associated with unprecedented environmental, social and technological changes. The impacts of colonisation, intergenerational trauma, racism and socioeconomic disadvantage intensify these challenges for many Aboriginal and Torres Strait Islander adolescents. However, Aboriginal and Torres Strait Islander adolescents also have cultural, spiritual, family and community capital that fosters their well-being.

To date, little research has focused on understanding and appropriately measuring the well-being of Aboriginal and Torres Strait Islander adolescents, a pivotal factor in informing and guiding programmes and interventions that support them. This study will identify the domains of well-being and develop a new preference-based well-being measure based on the values and preferences of Aboriginal and Torres Strait Islander youth (aged 12–17 years).

Methods and analysis

This project will be conducted across three research phases: (1) qualitative exploration of well-being using PhotoYarning and yarns with adult mentors to develop candidate items; (2) Think Aloud study, quantitative survey, psychometric analysis, validity testing of candidate items and finalisation of the descriptive system; and (3) scoring development using a quantitative preference-based approach. A multinomial (conditional) logit framework will be used to analyse responses and generate a scoring algorithm for the new preference-based well-being measure.

Ethics and dissemination

Ethics approvals have been obtained from: the Human Research Ethics Committees for each state and territory where data are being collected, the institutions where the research is being conducted and from the relevant Departments of Education. The new well-being measure will have wide applicability and can be used in assessing the effectiveness of programmes and services. This new national measure will ensure benefit and positive impact through the ability to identify and measure the aspects of well-being important to and valued by Aboriginal and Torres Strait Islander youth. Results will be published in international peer-reviewed journals and presented at conferences, and summaries will be provided to the study partner organisations and other relevant organisations.

Evolution of the data and methods in real-world COVID-19 vaccine effectiveness studies on mortality: a scoping review protocol

Por: Stehlik · P. · Dowsett · C. · Camacho · X. · Falster · M. O. · Lim · R. · Nasreen · S. · Pratt · N. L. · Pearson · S.-A. · Henry · D.
Background

Early evidence on COVID-19 vaccine efficacy came from randomised trials. Many important questions subsequently about vaccine effectiveness (VE) have been addressed using real-world studies (RWS) and have informed most vaccination policies globally. As the questions about VE have evolved during the pandemic so have data, study design, and analytical choices. This scoping review aims to characterise this evolution and provide insights for future pandemic planning—specifically, what kinds of questions are asked at different stages of a pandemic, and what data infrastructure and methods are used?

Methods and analysis

We will identify relevant studies in the Johns Hopkins Bloomberg School of Public Health VIEW-hub database, which curates both published and preprint VE RWS identified from PubMed, Embase, Scopus, Web of Science, the WHO COVID Database, MMWR, Eurosurveillance, medRxiv, bioRxiv, SSRN, Europe PMC, Research Square, Knowledge Hub, and Google. We will include RWS of COVID-19 VE that reported COVID-19-specific or all-cause mortality (coded as ‘death’ in the ‘effectiveness studies’ data set).

Information on study characteristics; study context; data sources; design and analytic methods that address confounding will be extracted by single reviewer and checked for accuracy and discussed in a small group setting by methodological and analytic experts. A timeline mapping approach will be used to capture the evolution of this body of literature.

By describing the evolution of RWS of VE through the COVID-19 pandemic, we will help identify options for VE studies and inform policy makers on the minimal data and analytic infrastructure needed to support rapid RWS of VE in future pandemics and of healthcare strategies more broadly.

Ethics and dissemination

As data is in the public domain, ethical approval is not required. Findings of this study will be disseminated through peer-reviewed publications, conference presentations, and working-papers to policy makers.

Introduction

Children and adolescents with mature B cell non-Hodgkin lymphoma (B-NHL) are treated with short-intensive chemotherapy. The burden of short-term and long-term toxicity is highly relative to its high cure rate in good-risk patients. Although the addition of rituximab to standard lymphome Malin B (LMB) chemotherapy markedly prolongs event-free survival and overall survival in high-risk patients, the benefit of rituximab in good-risk patients remains to be elucidated. This clinical trial will examine whether the addition of rituximab eliminates anthracyclines in good-risk patients without compromising treatment outcomes.

Methods and analysis

We will perform a single-arm, open-label, multicentre phase II study. Low-risk (stage I – completely resected, stage II abdominal) and intermediate-risk (stages I and II – incompletely resected; stage II – resected, other than abdominal; stage III with LDH x upper limit of normal) patients with newly diagnosed B-NHL are eligible. Low-risk patients receive two courses of R-COM1P (rituximab, cyclophosphamide, vincristine, methotrexate, prednisolone and intrathecal methotrexate with hydrocortisone), and intermediate-risk patients receive COP (cyclophosphamide, vincristine, prednisolone and intrathecal methotrexate with hydrocortisone) followed by two courses each of R-COM3P and R-CYM (rituximab, cytarabine, methotrexate and intrathecal methotrexate with hydrocortisone). The primary endpoint is a 3-year event-free survival rate in paediatric patients (

Inequities and trends of polio immunisation among children aged 12-23 months in Ethiopia: a multilevel analysis of Ethiopian demographic and health survey

Por: Fekadu · H. · Mekonnen · W. · Adugna · A. · Kloos · H. · HaileMariam · D.
Introduction

Despite Ethiopia’s policy intention to provide recommended vaccination services to underprivileged populations, inequity in polio immunisation persists.

Objective

This study examined inequity and trends in polio immunisation and determinant factors among children aged 12–23 months in Ethiopia between 2000 and 2019.

Methods

Cross-sectional data from 2000, 2005, 2011, 2016 and 2019 Ethiopian demographic and health surveys were analysed with the updated version of the WHO’s Health Equity Assessment Toolkit software. Six standard equity measures: equity gaps, equity ratios, population attributable risk, population attributable fraction, slope index of inequality and relative index of inequality were used. Datasets were analysed and disaggregated by the five equality stratifiers: economic status, education, place of residence, sex of the child and regions. Multilevel logistic regression analysis was used to identify determinant factors.

Results

Polio immunisation coverage was increased from 34.5% (2000) to 60.0% (2019). The wealth index-related inequity, in coverage of polio immunisation between quintiles 5 and 1, was 20 percentage points for most surveys. The population attributable risk and population attributable fraction measure in 2011 indicate that the national polio immunisation coverage in that year could have been improved by nearly 36 and 81 percentage points, respectively, if absolute and relative wealth-driven inequity, respectively, had been avoided. The absolute difference between Addis Ababa and Afar Region was 74 percentage points in 2000 and 60 percentage points in 2019. In multilevel analysis result, individual-level factors like wealth index, maternal education antenatal care and place of delivery showed statistical significance.

Conclusion

Although polio immunisation coverage gradually increased over time, in the 20-year survey periods, still 40% of children remained unvaccinated. Inequities in coverage by wealth, educational status, urban–rural residence and administrative regions persisted. Increasing service coverage and improving equitable access to immunisations services may narrow the existing inequity gaps.

Exploring the experiences of mental health nurses in the management of schizophrenia in the Upper East Region of Ghana: a qualitative study

Por: Daliri · D. B. · Laari · T. T. · Abagye · N. · Afaya · A.
Objective

Schizophrenia is a chronic condition, of which the diagnosis and management require comprehensive care. The role mental health nurses play in this management cannot be overemphasised. In an effort to give their best, several challenges confront them which need to be sought and addressed. This study aimed to explore the factors that influence the management of schizophrenia by mental health nurses in the Upper East Region.

Design and participants

A descriptive phenomenology design was used in this study. Individual in-depth interviews were conducted among 18 purposively sampled mental health nurses using a semistructured interview guide. Audio-recorded interviews were transcribed verbatim and analysed thematically using Colaizzi’s approach.

Setting

The study was conducted in five primary and secondary-level health facilities in the Upper East Region of Ghana.

Findings

Five themes were deduced from the theoretical framework, which were as follows: individual factors, interpersonal factors, organisational factors, community-level factors, and policy-level factors. At the individual level, factors such as the condition of the patient at presentation, medication side effects, inadequate knowledge, and poor adherence were identified. Interpersonal factors identified were poor communication, lack of mutual respect, and poor communication, while organisational factors such as inadequate staff, inadequate infrastructure and logistics, and unavailability of antipsychotics were reported. Moreover, the study identified community-level factors such as stigma and cultural beliefs, while policy-level factors such as laws regarding suicide, patient rights, and non-inclusion of mental health services into the National Health Insurance Scheme were reported as factors influencing the management of schizophrenia by mental health nurses.

Conclusions

Addressing these factors is essential to ensure sustainable improvements and the effective management of schizophrenia. It is imperative to consider these factors when designing interventions and policies to optimise the management of schizophrenia by mental health nurses in Ghana.

Association between individual-level socioeconomic factors and intimate partner violence victimisation in women: a systematic review protocol

Por: Reyal · H. P. · Dissanayake · N. · Gunarathna · H. · Soysa · D. · Fernando · M. S. · Senarathna · L.
Introduction

Intimate partner violence (IPV) is a global public health problem. Although both men and women experience IPV, the burden is more on women. To address IPV effectively, it is important to understand the factors that cause IPV including the socioeconomic factors. However, there is an inadequacy of knowledge on how socioeconomic factors at different levels affect IPV. Hence, the objective is to review the individual-level socioeconomic factors associated with IPV victimisation of women and girls.

Methods and analysis

The search strategy was developed to identify publications from January 2010 to 30 June 2024. The selected electronic databases of PubMed/MEDLINE, EMBASE, CINAHL, PsycINFO, Web of Science, Scopus and Science Direct will be searched. The eligibility criteria for data collection are based on participants/population (women and girls), exposure (socioeconomic factors) and outcome (IPV). In primary search, the title and abstracts will be screened and reference lists of selected articles will be screened for additional studies. Two researchers will independently screen the articles, and in any disagreements, a third researcher will be consulted. The data will be tabulated to present the study and participant characteristics, comparison descriptors between victims and non-victims, inclusion and exclusion criteria, primary and secondary outcomes data, results, limitations and implications. A quality assessment will be performed on the selected studies to avoid bias. A narrative synthesis will summarise the findings.

Ethics and dissemination

Ethical approval was waived because only secondary data are used. The protocol will be published, and the findings will be disseminated via publication in a peer-reviewed journal.

Evaluating the impact of movement tracking feedback on engagement with home exercise programmes of children with cerebral palsy using a new therapy app: a protocol for a mixed-methods single-case experimental design with alternating treatments

Por: Petrevska · M. · Wright · F. V. · Khan · A. · Munce · S. · Fehlings · D. · Biddiss · E.
Introduction

Children with cerebral palsy (CP) are prescribed home exercise programmes (HEPs) to increase the frequency of movement practice, yet adherence to HEPs can be low. This paper outlines the protocol for a single-case experimental design (SCED) with alternating treatments, using a new home therapy exercise application, Bootle Boot Camp (BBCamp), offered with and without movement tracking feedback. This study will explore the impact of feedback on engagement, movement quality, lower limb function and family experiences to help understand how technology-supported HEPs should be translated and the added value, if any, of movement tracking technology.

Methods and analysis

In this explanatory sequential mixed-methods study using a SCED, 16 children with CP (aged 6–12 years, Gross Motor Function Classification System levels I–II) will set lower limb goals and be prescribed an individualised HEP by their physiotherapist to complete using BBCamp on their home television equipped with a three-dimensional camera-computer system. Children will complete four weekly exercise sessions over 6 weeks. Children will be randomised to 1 of 16 alternating treatment schedules where BBCamp will provide or withhold feedback during the first 4 weeks. The version of BBCamp that results in the most therapeutic benefit will be continued for 2 final weeks. Goals will be re-evaluated and families interviewed. The primary outcome is adherence (proportion of prescribed exercise repetitions attempted) as a measure of behavioural engagement. Secondary outcomes are affective and cognitive engagement (smiley face ratings), exercise fidelity, lower limb function, goal achievement and participant experiences. SCED data will be analysed using visual and statistical methods. Quantitative and qualitative data will be integrated using joint displays.

Ethics and dissemination

Ethical approval was obtained from the Research Ethics Boards at Bloorview Research Institute and the University of Toronto. Results will be distributed through peer-reviewed journals and scientific conferences.

Physician characteristics associated with antiviral prescriptions for older adults with COVID-19 in Japan: an observational study

Por: Miyawaki · A. · Kitajima · K. · Iwata · A. · Sato · D. · Tsugawa · Y.
Objectives

Although guidelines recommend antiviral therapy for outpatients with COVID-19 who are at high risk of progressing to severe conditions, such as older adults, many patients do not receive appropriate treatment. Little is known, however, about the physician factors associated with the prescription of guideline-recommended antiviral therapy for patients with COVID-19.

Design

A cross-sectional study.

Setting

Data including outpatient visits in primary care clinics in Japan from April to August 2023.

Participants

We analysed 30 953 outpatients aged ≥65 years treated with COVID-19 (mean (SD) age, 75.0 (7.6) years; 17 652 women (57.0%)) in 1394 primary care clinics.

Outcome measures

The primary outcome was the prescription of guideline-recommended antivirals (ie, nirmatrelvir–ritonavir or molnupiravir), adjusted for patient characteristics, months of visits and regions.

Results

Antiviral prescriptions were concentrated among a small proportion of physicians; for example, the top 10% of physicians that had the largest number of nirmatrelvir–ritonavir prescriptions accounted for 92.4% of all nirmatrelvir–ritonavir prescriptions. After adjusting for potential confounders, physicians with higher patient volumes were more likely to prescribe guideline-recommended antivirals to their patients (adjusted OR (aOR) for high vs low volume, 1.76; 95% CI 1.31 to 2.38; adjusted p

Conclusions

Our findings suggest that provider-level factors, such as the clinical experience of treating the patients with COVID-19, play an important role in the appropriate prescription of antiviral medications for COVID-19 in the primary care setting.
