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.

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.

Introduction

Deep brain stimulation (DBS) can be used to treat several neurological and psychiatric conditions such as Parkinson’s disease, epilepsy and obsessive-compulsive disorder; however, limited work has been done to assess the disparities in DBS access and implementation. The goal of this scoping review is to identify sources of disparity in the clinical provision of DBS.

Methods and analysis

A scoping review will be conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-extension for Scoping Reviews methodology. Relevant studies will be identified from databases including MEDLINE/PubMed, EMBASE and Web of Science, as well as reference lists from retained articles. Initial search dates were in January 2023, with the study still ongoing. An initial screening of the titles and abstracts of potentially eligible studies will be completed, with relevant studies collected for full-text review. The principal investigators and coauthors will then independently review all full-text articles meeting the inclusion criteria. Data will be extracted and collected in table format. Finally, results will be synthesised in a table and narrative report.

Ethics and dissemination

No institutional board review or approval is necessary for the proposed scoping review. The findings will be submitted for publication to relevant peer-reviewed journals and conferences.

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.

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.

Investigation of divergent thinking among surgeons and surgeon trainees in Canada (IDEAS): a mixed-methods study

Por: Thabane · A. · McKechnie · T. · Arora · V. · Calic · G. · Busse · J. W. · Sonnadara · R. · Bhandari · M. — Marzo 21st 2024 at 16:38
Objective

To assess the creative potential of surgeons and surgeon trainees, as measured by divergent thinking. The secondary objectives were to identify factors associated with divergent thinking, assess confidence in creative problem-solving and the perceived effect of surgical training on creative potential, and explore the value of creativity in surgery.

Design

We used a mixed-methods design, conducting a survey of divergent thinking ability using a validated questionnaire followed by two semi-structured interviews with top-scoring participants.

Participants & setting

Surgeons and surgeon trainees in the Department of Surgery at McMaster University.

Outcomes

The primary outcome was divergent thinking, assessed with the Abbreviated Torrance Test for Adults. Participants also self-assessed their confidence in creative problem-solving and the effect of surgical training on their creative potential. We performed descriptive analyses and multivariable linear regression to identify factors associated with divergent thinking. We conducted a thematic analysis of the interview responses.

Results

82 surgeons and surgeon trainees were surveyed; 43 were junior trainees and 28 were senior trainees. General surgery, orthopaedic surgery and plastic surgery represented 71.9% of the participants. The median participant age was 28 years (range 24–73), 51.2% of whom were female. Participants demonstrated levels of divergent thinking that were higher but not meaningfully different from the adult norm (62.39 (95% CI 61.25, 63.53), p

Conclusions

The divergent thinking ability among surgeons and surgeon trainees was not meaningfully different from the adult normative score; however, their ability to generate original ideas was below average.

Maternal and household factors affecting the dietary diversity of preschool children in eastern Ethiopia: a cross-sectional study

Por: Roba · A. A. · Basdas · O. · Brewis · A. · Roba · K. T. — Marzo 21st 2024 at 16:38
Objective

Investigate the association between the dietary diversity of preschool children and proximate factors including household food insecurity, maternal food choice, preferences, khat use, and levels of depressive symptoms.

Design

Cross-sectional survey of randomly selected households.

Setting

Haramaya Health and Demographic Surveillance site in Eastern Ethiopia, predominantly smallholder farming households.

Participants

678 preschool children (24–59 months) and their mothers.

Methods

The key outcome, the adequacy of dietary diversity of preschool children, was calculated using a 24-hour parental dietary recall. Binary logistic regression was then used to identify maternal and household factors associated with dietary adequacy versus inadequacy.

Results

The majority (80.53%) of surveyed children had low dietary diversity (mean Dietary Diversity (MDD)) score of 3.06±1.70 on a 7-point scale). Approximately 80% of households exhibited food insecurity. Households with greater food security (adjusted OR (AOR)=1.96, 95% CI 1.19 to 3.23), healthier maternal food choice (AOR=2.19, 95% CI 1.12 to 4.31) and broader maternal food preferences (AOR=4.95, 95% CI 1.11 to 21.95) were all associated with higher dietary diversity of their preschool children (p≤0.05). Other covariates associated with adequate child dietary diversity included improved household drinking water sources (AOR=1.84, 95% CI 1.16 to 2.92) and family planning use (AOR=1.69, 95% CI 1.00 to 2.86). Despite predictions, however, maternal depression and khat consumption were not identified as factors.

Conclusions

The dietary diversity of preschool children is extremely low—a pattern observed in both food-secure and food-insecure households. Key factors include maternal selection of food for convenience and ease, preferences that do not include animal protein or healthier food choices, and lack of access to improved drinking water sources. Interventions around maternal food choice and preferences could improve preschool children’s nutritional health.

Identifying provider, patient and practice factors that shape long-term opioid prescribing for cancer pain: a qualitative study of American and Australian providers

Por: Fereydooni · S. · Lorenz · K. · Azarfar · A. · Luckett · T. · Phillips · J. L. · Becker · W. · Giannitrapani · K. — Marzo 21st 2024 at 16:38
Introduction

Prescribing long-term opioid therapy is a nuanced clinical decision requiring careful consideration of risks versus benefits. Our goal is to understand patient, provider and context factors that impact the decision to prescribe opioids in patients with cancer.

Methods

We conducted a secondary analysis of the raw semistructured interview data gathered from 42 prescribers who participated in one of two aligned concurrent qualitative studies in the USA and Australia. We conducted a two-part analysis of the interview: first identifying all factors influencing long-term prescribing and second open coding-related content for themes.

Results

Factors that influence long-term opioid prescribing for cancer-related pain clustered under three key domains (patient-related, provider-related and practice-related factors) each with several themes. Domain 1: Patient factors related to provider–patient continuity, patient personality, the patient’s social context and patient characteristics including racial/ethnic identity, housing and socioeconomic status. Domain 2: Provider-related factors centred around provider ‘personal experience and expertise’, training and time availability. Domain 3: Practice-related factors included healthcare interventions to promote safer opioid practices and accessibility of quality alternative pain therapies.

Conclusion

Despite the differences in the contexts of the two countries, providers consider similar patient, provider and practice-related factors when long-term prescribing opioids for patients with cancer. Some of these factors may be categorised as cognitive biases that may intersect in an already disadvantaged patient and exacerbate disparities in the treatment of their pain. A more systematic understanding of these factors and how they impact the quality of care can inform appropriate interventions.

Cohort profile: The Health, Food, Purchases and Lifestyle (SMIL) cohort - a Danish open cohort

Por: Sorensen · K. K. · Andersen · M. P. · Moller · F. T. · Eves · C. · Junker · T. G. · Zareini · B. · Torp-Pedersen · C. — Marzo 20th 2024 at 16:56
Purpose

The Health, Food, Purchases and Lifestyle (SMIL) cohort is a prospective open Danish cohort that collects electronic consumer purchase data, which can be linked to Danish nationwide administrative health and social registries. This paper provides an overview of the cohort’s baseline characteristics and marginal differences in the monetary percentage spent on food groups by sex, age and hour of the day.

Participants

As of 31 December 2022, the cohort included 11 214 users of a smartphone-based receipt collection application who consented to share their unique identification number for linkage to registries in Denmark. In 2022, the composition of the cohort was as follows: 62% were men while 24% were aged 45–55. The cohort had a median of 63 (IQR 26–116) unique shopping trips. The cohort included participants with a range of health statuses. Notably, 21% of participants had a history of cardiovascular disease and 8% had diabetes before donating receipts.

Findings to date

The feasibility of translating consumer purchase data to operationalisable food groups and merging with registers has been demonstrated. We further demonstrated differences in marginal distributions which revealed disparities in the amount of money spent on various food groups by sex and age, as well as systematic variations by the hour of the day. For example, men under 30 spent 8.2% of their total reported expenditure on sugary drinks, while women under 30 spent 6.5%, men over 30 spent 4.3% and women over 30 spent 3.9%.

Future plans

The SMIL cohort is characterised by its dynamic, continuously updated database, offering an opportunity to explore the relationship between diet and disease without the limitations of self-reported data. Currently encompassing data from 2018 to 2022, data collection is set to continue. We expect data collection to continue for many years and we are taking several initiatives to increase the cohort.

Introduction

SCALE-UP II aims to investigate the effectiveness of population health management interventions using text messaging (TM), chatbots and patient navigation (PN) in increasing the uptake of at-home COVID-19 testing among patients in historically marginalised communities, specifically, those receiving care at community health centres (CHCs).

Methods and analysis

The trial is a multisite, randomised pragmatic clinical trial. Eligible patients are >18 years old with a primary care visit in the last 3 years at one of the participating CHCs. Demographic data will be obtained from CHC electronic health records. Patients will be randomised to one of two factorial designs based on smartphone ownership. Patients who self-report replying to a text message that they have a smartphone will be randomised in a 2x2x2 factorial fashion to receive (1) chatbot or TM; (2) PN (yes or no); and (3) repeated offers to interact with the interventions every 10 or 30 days. Participants who do not self-report as having a smartphone will be randomised in a 2x2 factorial fashion to receive (1) TM with or without PN; and (2) repeated offers every 10 or 30 days. The interventions will be sent in English or Spanish, with an option to request at-home COVID-19 test kits. The primary outcome is the proportion of participants using at-home COVID-19 tests during a 90-day follow-up. The study will evaluate the main effects and interactions among interventions, implementation outcomes and predictors and moderators of study outcomes. Statistical analyses will include logistic regression, stratified subgroup analyses and adjustment for stratification factors.

Ethics and dissemination

The protocol was approved by the University of Utah Institutional Review Board. On completion, study data will be made available in compliance with National Institutes of Health data sharing policies. Results will be disseminated through study partners and peer-reviewed publications.

Self-help friendliness and cooperation with self-help groups among rehabilitation clinics in Germany (KoReS): a mixed-methods study protocol

Por: Ziegler · E. · Bartzsch · T. · Trojan · A. · Usko · N. · Krahn · I. · Bütow · S. · Kofahl · C. — Marzo 20th 2024 at 16:56
Introduction

Self-help is an important complement to medical rehabilitation for people with chronic diseases and disabilities. It contributes to stabilising rehabilitation success and further coping with disease and disability. Rehabilitation facilities are central in informing and referring patients to self-help groups. However, sustainable cooperation between rehabilitation and self-help, as can be achieved using the concept of self-help friendliness in healthcare, is rare, as is data on the cooperation situation.

Methods and analysis

The KoReS study will examine self-help friendliness and cooperation between rehabilitation clinics and self-help associations in Germany, applying a sequential exploratory mixed-methods design. In the first qualitative phase, problem-centred interviews and focus groups are conducted with representatives of self-help-friendly rehabilitation clinics, members of their cooperating self-help groups and staff of self-help clearinghouses involved based on a purposeful sampling. Qualitative data collected will be analysed through content analysis using MAXQDA. The findings will serve to develop a questionnaire for a quantitative second phase. Cross-sectional online studies will survey staff responsible for self-help in rehabilitation clinics nationwide, representatives of self-help groups and staff of self-help clearinghouses. Quantitative data analysis with SPSS will include descriptive statistics, correlation, subgroup and multiple regression analyses. Additionally, a content analysis of rehabilitation clinics’ websites will evaluate the visibility of self-help in their public relations.

Ethics and dissemination

The University Medical Center Hamburg-Eppendorf Local Psychological Ethics Committee at the Center for Psychosocial Medicine granted ethical approval (reference number LPEK-0648; 10.07.2023). Informed consent will be obtained from all participants. Results dissemination will comprise various formats such as workshops, presentations, homepages and publications for the international scientific community, rehabilitation centres, self-help organisations and the general public in Germany. For relevant stakeholders, practical guides and recommendations to implement self-help friendliness will derive from the results to strengthen patient orientation and cooperation between rehabilitation and self-help to promote the sustainability of rehabilitation processes.

Role of physical activity in the relationship between recovery from work and insomnia among early childhood education and care professionals: a cross-sectional study

Por: Karihtala · T. · Puttonen · S. · Valtonen · A. M. · Kautiainen · H. · Hopsu · L. · Heinonen · A. — Marzo 20th 2024 at 05:26
Objectives

This study aimed to investigate the association between recovery from work and insomnia and the role of objectively measured leisure-time physical activity and occupational physical activity in this association.

Design

Cross-sectional.

Setting and participants

Study with female early childhood education and care professionals (N=224) in Finland was conducted between April 2017 and September 2018.

Methods

Recovery from work was measured with the Need for Recovery scale and insomnia with the Jenkins Sleep Scale. Physical activity was measured with an accelerometer for 7 days and analysed to represent leisure-time physical activity and occupational physical activity (min/day).

Results

Both Jenkins Sleep Scale and occupational physical activity significantly predicted Need for Recovery (β=0.29; 95% CI 0.17 to 0.42 and β=0.14; 95% CI 0.01 to 0.27, respectively). A low relationship was observed between the Need for Recovery and Jenkins Sleep Scale (r=0.32, 95% Cl 0.19 to 0.44). After categorising participants into four groups based on median splits of occupational and leisure-time physical activity, relationships between the Need for Recovery and Jenkins Sleep Scale were low to moderate in the high occupational physical activity and leisure time physical activity group (r=0.38, 95% Cl 0.14 to 0.61), and in the high occupational physical activity and low leisure-time physical activity group (r=0.40, 95% Cl 0.18 to 0.63).

Conclusion

Both insomnia and physical activity at work seem to be relevant in recovery from work. To enhance recovery, especially those involved in high physical activity at work, should seek methods to improve recovery, by incorporating activities that promote recuperation both during their workday and in their leisure time. Further research on the relevance of physical activity in recovery with longitudinal setting is warranted.

Perceptions and experiences of paramedics managing people with non-traumatic low back pain: a qualitative study of Australian paramedics

Por: Vella · S. P. · Simpson · P. · Bendall · J. C. · Pickles · K. · Copp · T. · Swain · M. S. · Maher · C. G. · Machado · G. C. — Marzo 20th 2024 at 05:26
Background

Paramedics are often first providers of care to patients experiencing non-traumatic low back pain (LBP), though their perspectives and experiences with managing these cases remain unclear.

Objectives

This study explored paramedic views of the management of non-traumatic LBP including their role and experience with LBP management, barriers to referral and awareness of ambulance service guidelines.

Design

Qualitative study using semistructured interviews conducted between January and April 2023.

Setting

New South Wales Ambulance service.

Participants

A purposive sample of 30 paramedics of different specialities employed by New South Wales Ambulance were recruited.

Results

Paramedic accounts demonstrated the complexity, challenge, frustration and reward associated with managing non-traumatic LBP. Paramedics perceived that their primary role focused on the assessment of LBP, and that calls to ambulance services were often driven by misconceptions surrounding the management of LBP, and a person’s pain severity. Access to health services, patient factors, defensive medicine, paramedic training and education and knowledge of guidelines influenced paramedic management of LBP.

Conclusion

Paramedics often provide care to non-traumatic LBP cases yet depending on the type of paramedic speciality find these cases to be frustrating, challenging or rewarding to manage due to barriers to referral including access to health services, location, patient factors and uncertainty relating to litigation. Future research should explore patient perspectives towards ambulance service use for the management of their LBP.

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. — Marzo 20th 2024 at 03:21
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.

Introduction

Effective communication can help optimise healthcare interactions and patient outcomes. However, few interventions have been tested clinically, subjected to cost-effectiveness analysis or are sufficiently brief and well-described for implementation in primary care. This paper presents the protocol for determining the effectiveness and cost-effectiveness of a rigorously developed brief eLearning tool, EMPathicO, among patients with and without musculoskeletal pain.

Methods and analysis

A cluster randomised controlled trial in general practitioner (GP) surgeries in England and Wales serving patients from diverse geographic, socioeconomic and ethnic backgrounds. GP surgeries are randomised (1:1) to receive EMPathicO e-learning immediately, or at trial end. Eligible practitioners (eg, GPs, physiotherapists and nurse practitioners) are involved in managing primary care patients with musculoskeletal pain. Patient recruitment is managed by practice staff and researchers. Target recruitment is 840 adults with and 840 without musculoskeletal pain consulting face-to-face, by telephone or video. Patients complete web-based questionnaires at preconsultation baseline, 1 week and 1, 3 and 6 months later. There are two patient-reported primary outcomes: pain intensity and patient enablement. Cost-effectiveness is considered from the National Health Service and societal perspectives. Secondary and process measures include practitioner patterns of use of EMPathicO, practitioner-reported self-efficacy and intentions, patient-reported symptom severity, quality of life, satisfaction, perceptions of practitioner empathy and optimism, treatment expectancies, anxiety, depression and continuity of care. Purposive subsamples of patients, practitioners and practice staff take part in up to two qualitative, semistructured interviews.

Ethics approval and dissemination

Approved by the South Central Hampshire B Research Ethics Committee on 1 July 2022 and the Health Research Authority and Health and Care Research Wales on 6 July 2022 (REC reference 22/SC/0145; IRAS project ID 312208). Results will be disseminated via peer-reviewed academic publications, conference presentations and patient and practitioner outlets. If successful, EMPathicO could quickly be made available at a low cost to primary care practices across the country.

Health risks of exposure to air pollution in areas where coal-fired power plants are located: protocol for a scoping review

Por: Mahlangeni · N. · Kapwata · T. · Laban · T. · Wright · C. Y. — Marzo 20th 2024 at 03:21
Introduction

Coal-fired power plants are major sources of air pollution which impact human health. Coal combustion byproducts released into the air include particulate matter, nitrogen oxides and sulphur dioxide. Exposure to fine particulate matter is associated with increased risk of mortality. This scoping review will examine and summarise the current literature on the health risks of exposure to air pollution in areas in which coal-fired power plants exist.

Methods and analysis

This scoping review will be conducted according to the Joanna Briggs Institute methodological framework and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. Five electronic databases (PubMed, ScienceDirect, Scopus, Web of Science and Google Scholar) will be searched for relevant articles. Studies will be included up until 31 January 2024. There will be no restriction on geographical area. The searches will be limited to studies published in English. Title, abstract, full-text screening and data extraction of relevant articles will be done by two independent reviewers. Discrepancies will be resolved by group discussion. The findings will be presented in tables with a narrative summary. This review will consider epidemiological studies and grey literature that report on the health risks of exposure to air pollution in areas where coal-fired power plants exist.

Ethics and dissemination

All data will be collected from published and grey literature. Ethics approval is therefore not required. We will submit our findings for publication in a peer-reviewed journal.

IMproving psYchosocial adjustment to Traumatic Brain Injury from acute to chronic injury through development and evaluation of the myTBI online psychoeducation platform: protocol for a mixed-methods study

Por: Troeung · L. · Sarunga Raja · T. L. · Mann · G. · Wagland · J. · MacLeod · C. · Martini · A. — Marzo 20th 2024 at 03:21
Introduction

This protocol describes the myTBI study which aims to: (1) develop an online psychoeducation platform for people with traumatic brain injury (TBI), their family members/caregivers, and healthcare staff to improve psychosocial adjustment to TBI across different phases of injury (acute, postacute, and chronic), and (2) undertake an evaluation of efficacy, acceptability, and feasibility.

Methods and analysis

A three-stage mixed-methods research design will be used. The study will be undertaken across four postacute community-based neurorehabilitation and disability support services in Western Australia. Stage 1 (interviews and surveys) will use consumer-driven qualitative methodology to: (1) understand the recovery experiences and psychosocial challenges of people with TBI over key stages (acute, postacute, and chronic), and (2) identify required areas of psychosocial support to inform the psychoeducation platform development. Stage 2 (development) will use a Delphi expert consensus method to: (1) determine the final psychoeducation modules, and (2) perform acceptance testing of the myTBI platform. Finally, stage 3 (evaluation) will be a randomised stepped-wedge trial to evaluate efficacy, acceptability, and feasibility. Outcomes will be measured at baseline, postintervention, follow-up, and at final discharge from services. Change in outcomes will be analysed using multilevel mixed-effects modelling. Follow-up surveys will be conducted to evaluate acceptability and feasibility.

Ethics and dissemination

Ethics approval was granted by North Metropolitan Health Service Mental Health Research Ethics and Governance Office (RGS0000005877). Study findings will be relevant to clinicians, researchers, and organisations who are seeking a cost-effective solution to deliver ongoing psychoeducation and support to individuals with TBI across the recovery journey.

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 (

Socioeconomic inequalities in skilled attendance at birth and caesarean section rates in Myanmar 2015-2016: a cross-sectional study

Por: Show · K. L. · Maung · T. M. · Disney · G. · Bohren · M. A. · Lumbiganon · P. · Ngamjarus · C. — Marzo 19th 2024 at 04:02
Objectives

This study aims to assess inequalities in skilled birth attendance and utilisation of caesarean section (CS) in Myanmar.

Study design

Cross-sectional study design.

Setting and population

We used secondary data from the Myanmar Demographic and Health Survey (2015–2016). Our outcome measures of skilled birth attendance and utilisation of CS were taken from the most recent birth of interviewed women. Absolute and relative inequalities across several sociodemographic characteristics were assessed and evaluated by calculating rate differences, rate ratio and concentration indexes.

Results

More than one-third (36%, 95% CI 32.5% to 39.4%) of women gave birth without a skilled birth attendant present at their most recent birth. 40.7% (95% CI 37.8% to 43.7%) gave birth in healthcare facilities, and the CS rate was 19.7% (95% CI 17.9% to 21.8%) for their most recent birth. The highest proportion of birth without a skilled provider was found in the hilly regions and rural residents, poorest and less educated women, and those with less than four antenatal care visits. Inequalities in birth without a skilled provider were observed across regions, place of residence, wealth quintile, education level and number of antenatal care taken. The highest rate of CS was found among plain regions and urban residents, richest women, more than secondary education, those with more than four antenatal care visits and in private health facilities. Inequalities in CS utilisation were observed across place of residence, wealth quintiles, education level, number of antenatal care taken and type of health facilities.

Conclusion

This study provides evidence regarding inequalities in maternal health service utilisation in Myanmar. Increasing maternal health service availability and accessibility, promoting quality of care and health education campaigns to increase maternal health services utilisation are recommended.

Introduction

Diffuse intrinsic pontine glioma (DIPG) and paediatric high-grade glioma (pHGG) are aggressive glial tumours, for which conventional treatment modalities fall short. Dendritic cell (DC)-based immunotherapy is being investigated as a promising and safe adjuvant therapy. The Wilms’ tumour protein (WT1) is a potent target for this type of antigen-specific immunotherapy and is overexpressed in DIPG and pHGG. Based on this, we designed a non-randomised phase I/II trial, assessing the feasibility and safety of WT1 mRNA-loaded DC (WT1/DC) immunotherapy in combination with conventional treatment in pHGG and DIPG.

Methods and analysis

10 paediatric patients with newly diagnosed or pretreated HGG or DIPG were treated according to the trial protocol. The trial protocol consists of leukapheresis of mononuclear cells, the manufacturing of autologous WT1/DC vaccines and the combination of WT1/DC-vaccine immunotherapy with conventional antiglioma treatment. In newly diagnosed patients, this comprises chemoradiation (oral temozolomide 90 mg/m2 daily+radiotherapy 54 Gy in 1.8 Gy fractions) followed by three induction WT1/DC vaccines (8–10x106 cells/vaccine) given on a weekly basis and a chemoimmunotherapy booster phase consisting of six 28-day cycles of oral temozolomide (150–200 mg/m2 on days 1–5) and a WT1/DC vaccine on day 21. In pretreated patients, the induction and booster phase are combined with best possible antiglioma treatment at hand. Primary objectives are to assess the feasibility of the production of mRNA-electroporated WT1/DC vaccines in this patient population and to assess the safety and feasibility of combining conventional antiglioma treatment with the proposed immunotherapy. Secondary objectives are to investigate in vivo immunogenicity of WT1/DC vaccination and to assess disease-specific and general quality of life.

Ethics and dissemination

The ethics committee of the Antwerp University Hospital and the University of Antwerp granted ethics approval. Results of the clinical trial will be shared through publication in a peer-reviewed journal and presentations at conferences.
