Engaging people with lived experiences on community advisory boards in community-based participatory research: a scoping review protocol

Por: Nelson · G. · Kettaneh · H. · Knox · B. · Purkey · E. · Chan-Nguyen · S. · Jenkins · M. · Bayoumi · I.
Introduction

Community-based participatory research (CBPR) is a collaborative research approach that equally engages researchers and community stakeholders throughout all steps of the research process to facilitate social change and increase research relevance. Community advisory boards (CABs) are a CBPR tool in which individuals with lived experience and community organisations are integrated into the research process and ensure the work aligns with community priorities. We seek to (1) explore the best practices for the recruitment and engagement of people with lived experiences on CABs and (2) identify the scope of literature on minimising power dynamics between organisations and community members with lived experience who work on CABs together.

Methods and analysis

This scoping review will follow the Arksey and O’Malley methodological framework, informed by Levac et al, and will be reported using a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) diagram. Detailed and robust search strategies have been developed for Embase, Medline and PsychINFO. Grey literature references and reference lists of included articles published between 1 January 1990 and 30 March 2023 will be considered. Two reviewers will independently screen references in two successive stages of title/abstract and full-text screening. Conflicts will be decided by consensus or a third reviewer. Thematic analysis will be applied in three phases: open coding, axial coding and abstraction. Extracted data will be recorded and presented in a tabular format and/or graphical summaries, with a descriptive overview discussing how the research findings relate to the research questions. At this time, a preliminary search of peer-reviewed and grey literature has been conducted. Search results for peer-reviewed literature have been uploaded to Covidence for review and appraisal for relevance.

Ethics and dissemination

Formal ethics approval is not required for this review. Review findings will inform ongoing and future CBPR community advisory board dynamics.

The protocol has been registered prospectively on the Open Science Framework (https://doi.org/10.17605/OSF.IO/QF5D3)

<i>Bacillus subtilis</i> DNA fluorescent sensors based on hybrid MoS<sub>2</sub> nanosheets

by Son Hai Nguyen, Van-Nhat Nguyen, Mai Thi Tran

Although sensor technology has advanced with better materials, biomarkers, and fabrication and detection methods, creating a rapid, accurate, and affordable bacterial detection platform is still a major challenge. In this study, we present a combination of hybrid-MoS2 nanosheets and an amine-customized probe to develop a fast, sensitive biosensor for Bacillus subtilis DNA detection. Based on fluorescence measurements, the biosensor exhibits a detection range of 23.6–130 aM, achieves a detection limit of 18.7 aM, and was stable over four weeks. In addition, the high selectivity over Escherichia coli and Vibrio proteolyticus DNAs of the proposed Bacillus subtilis sensors is demonstrated by the fluorescence quenching effect at 558 nm. This research not only presents a powerful tool for B. subtilis DNA detection but also significantly contributes to the advancement of hybrid 2D nanomaterial-based biosensors, offering substantial promise for diverse applications in biomedical research and environmental monitoring.

Maternal and perinatal outcomes of hypertensive disorders in pregnancy: Insights from the National Hospital of Obstetrics and Gynecology in Vietnam

by Nguyen Thi Huyen Anh, Nguyen Manh Thang, Truong Thanh Huong

Introduction

Hypertension is the common disorder encountered during pregnancy, complicating 5% to 10% of all pregnancies. Hypertensive disorders in pregnancy (HDP) are also a leading cause of maternal and perinatal morbidity and mortality. The majority of feto-maternal complications due to HPD have occurred in the low- and middle-income countries. However, few studies have been done to assess the feto-maternal outcomes and the predictors of adverse perinatal outcome among women with HDP in these countries.

Methods

A prospective cohort study was conducted on women with HDP who were delivered at National Hospital of Obstetrics and Gynecology, Vietnam from March 2023 to July 2023. Socio-demographic and obstetrics characteristics, and feto-maternal outcomes were obtained by trained study staff from interviews and medical records. Statistical analysis was performed using SPSS version 26.0. Bivariate and multiple logistic regressions were done to determine factors associated with adverse perinatal outcome. A 95% confidence interval not including 1 was considered statically significant.

Results

A total of 255 women with HDP were enrolled. Regarding adverse maternal outcomes, HELLP syndrome (3.9%), placental abruption (1.6%), and eclampsia (1.2%) were three most common complications. There was no maternal death associated with HDP. The most common perinatal complication was preterm delivery developed in 160 (62.7%) of neonates. Eight stillbirths (3.1%) were recorded whereas the perinatal mortality was 6.3%. On bivariate logistic regression, variables such as residence, type of HDP, highest systolic BP, highest diastolic BP, platelet count, severity symptoms, and birth weight were found to be associated with adverse perinatal outcome. On multiple logistic regression, highest diastolic BP, severity symptoms, and birth weight were found to be independent predictors of adverse perinatal outcome.

Conclusion

Our study showed lower prevalence of stillbirth, perinatal mortality, and maternal complication compared to some previous studies. Regular antenatal care and early detection of abnormal signs during pregnancy help to devise an appropriate monitoring and treatment strategies for each women with HDP.

Mental health nurses' empathy towards consumers with dual diagnosis: A descriptive study

Abstract

Aim

This study aimed to assess mental health nurses' empathy towards consumers with dual diagnosis in Australian mental health settings. The research question was What is mental health nurses' empathy towards consumers with co-existing mental health and drug and alcohol problems?

Design and Methods

A cross-sectional survey was carried out to understand mental health nurses' empathy. The convenience sample included 96 mental health nurses from various mental health settings with experience working with consumers with dual diagnosis. We assessed empathy using the Toronto Empathy Questionnaire. We utilised SPSS™ software to analyse both the descriptive data and multiple-regression.

Results

The mean empathy score was 47.71 (SD 8.28). The analysis of the association between demographic variables and individual subscales showed an association between the clinical setting and empathy (p = .031) and sympathetic physiological arousal (p = .049). The work sector was associated with sympathetic physiological arousal (p = .045) and conspecific altruism (p = .008). Emotional contagion (β = .98, p < .001), emotional comprehension (β = 1.02, p < .001), sympathetic physiological arousal (β = 1.01, p < .001) and conspecific altruism (β = 10.23, p < .001) predicted mental health nurses' empathy.

Conclusions

This study found that most mental health nurses showed empathy towards consumers with dual diagnosis. Mental health nurses who are more empathetic towards their consumers experience emotional contagion. They understand emotions better, show sympathetic physiological responses and exhibit kind behaviour towards consumers.

Implications for the Profession and Patient Care

Further research is required to understand how mental health nurses adapt to consumers' emotional states in different mental health settings. This information can help clinicians make better decisions about care quality for consumers with dual diagnosis.

Impact

This study addressed mental health nurses' empathy towards consumers with dual diagnosis. Mental health nurses showed increased empathy towards consumers with dual diagnosis. The empathy levels vary based on age, clinical setting, work sector and work experience. Mental health nurses' empathy levels were predicted by emotional contagion, emotion comprehension, sympathetic physiological arousal and conspecific altruism. Empathy enhancement among mental health nurses, particularly towards consumers with dual diagnosis, is crucial and should be regarded as a top priority by healthcare leaders and educators.

Impact of COVID-19 on patterns of drug utilization: A case study at national hospital

by Minh-Anh Le-Dang, Hai-Yen Nguyen-Thi, Luyen Pham Dinh, Danh Le Ngoc, Nguyen Dang Tu Le, Hien Pham Thu, Dinh Thanh Le

Background

The Coronavirus disease of 2019 (COVID-19) pandemic and the corresponding mitigation measures have had a discernible impact on drug utilization among outpatients. However, limited research exists on the prescription trends in the elderly population during the pandemic period in Viet Nam.

Objectives

This study aims to analyze the effects of COVID-19 on outpatient drug utilization patterns at a national geriatric hospital in Ho Chi Minh City before and after the early onset of the pandemic.

Methods

Data was collected from the prescriptions and administration claims, encompassing the period from January 2016 to December 2022. The dataset was divided into two periods: Period 1: January 2016 to December 2020 and Period 2: January 2021 to December 2022. The drug utilization was measured using DDD/1000P (defined daily doses–DDD per 1000 prescriptions) on a monthly basis. The analysis employed interrupted time series using Autoregressive Integrated Moving Average (ARIMA) to detect changes in drug use levels and rates.

Results

A total of 1,060,507 and 644,944 outpatient prescriptions from Thong Nhat Hospital were included in Period 1 and Period 2, respectively. The median age of the patients were 58 in Period 1 and 67 years old in Period 2. The most common comorbidities were dyslipidemia, hypertension, and diabetes mellitus. In terms of medication utilization, cardiovascular drugs were the most frequently prescribed, followed by drugs active on the digestive and hormonal systems. The study observed significant surges in the number of prescriptions and the average number of drugs per prescription. However, there were no significant changes in the overall consumption of all drugs. Among the drug groups related to the cardiovascular system, three subgroups experienced a sudden and significant increase: cardiac therapy, beta-blocking agents, and antihypertensives, with increasing consumption levels of 1,177.73 [CI 95%: 79.29; 2,276.16], 73.32 [CI 95%: 28.18; 118.46], and 36.70 [CI 95%: 6.74; 66.66] DDD/1000P, respectively. On the other hand, there was a significant monthly decrease of -31.36 [CI 95%: -57.02; -5.70] DDD/1000P in the consumption of anti-inflammatory and antirheumatic products. Interestingly, there was a significant increase of 74.62 [CI 95%: -0.36; 149.60] DDD/1000P in the use of antigout preparations.

Conclusion

COVID-19 resulted in a sudden, non-significant increase in overall drug consumption levels among outpatients. Notably, our findings highlight significant increases in the utilization of three drug groups related to the cardiovascular system, specifically cardiac therapy, beta-blocking agents, and antihypertensives. Intriguingly, there was a statistically significant increase in the consumption of antigout preparations, despite a decline in the monthly consumption rate of non-steroidal anti-flammatory drugs (NSAIDs). Further studies in the following years are necessary to provide a more comprehensive understanding of the impact of COVID-19 on outpatient drug utilization patterns.

Introduction

Longitudinal studies can provide timely and accurate information to evaluate and inform COVID-19 control and mitigation strategies and future pandemic preparedness. The Optimise Study is a multidisciplinary research platform established in the Australian state of Victoria in September 2020 to collect epidemiological, social, psychological and behavioural data from priority populations. It aims to understand changing public attitudes, behaviours and experiences of COVID-19 and inform epidemic modelling and support responsive government policy.

Methods and analysis

This protocol paper describes the data collection procedures for the Optimise Study, an ongoing longitudinal cohort of ~1000 Victorian adults and their social networks. Participants are recruited using snowball sampling with a set of seeds and two waves of snowball recruitment. Seeds are purposively selected from priority groups, including recent COVID-19 cases and close contacts and people at heightened risk of infection and/or adverse outcomes of COVID-19 infection and/or public health measures. Participants complete a schedule of monthly quantitative surveys and daily diaries for up to 24 months, plus additional surveys annually for up to 48 months. Cohort participants are recruited for qualitative interviews at key time points to enable in-depth exploration of people’s lived experiences. Separately, community representatives are invited to participate in community engagement groups, which review and interpret research findings to inform policy and practice recommendations.

Ethics and dissemination

The Optimise longitudinal cohort and qualitative interviews are approved by the Alfred Hospital Human Research Ethics Committee (# 333/20). The Optimise Study CEG is approved by the La Trobe University Human Ethics Committee (# HEC20532). All participants provide informed verbal consent to enter the cohort, with additional consent provided prior to any of the sub studies. Study findings will be disseminated through public website (https://optimisecovid.com.au/study-findings/) and through peer-reviewed publications.

Persons diagnosed with COVID-19 in England in the Clinical Practice Research Datalink (CPRD): a cohort description

Por: Andersen · K. M. · McGrath · L. J. · Reimbaeva · M. · Mendes · D. · Nguyen · J. L. · Rai · K. K. · Tritton · T. · Tsang · C. · Malhotra · D. · Yang · J.
Objective

To create case definitions for confirmed COVID-19 diagnoses, COVID-19 vaccination status and three separate definitions of high risk of severe COVID-19, as well as to assess whether the implementation of these definitions in a cohort reflected the sociodemographic and clinical characteristics of COVID-19 epidemiology in England.

Design

Retrospective cohort study.

Setting

Electronic healthcare records from primary care (Clinical Practice Research Datalink, CPRD) linked to secondary care data (Hospital Episode Statistics) data covering 24% of the population in England.

Participants

2 271 072 persons aged 1 year and older diagnosed with COVID-19 in CPRD Aurum between 1 August 2020 and 31 January 2022.

Main outcome measures

Age, sex and regional distribution of COVID-19 cases and COVID-19 vaccine doses received prior to diagnosis were assessed separately for the cohorts of cases identified in primary care and those hospitalised for COVID-19 (primary diagnosis code of ICD-10 U07.1 ‘COVID-19’). Smoking status, body mass index and Charlson Comorbidity Index were compared for the two cohorts, as well as for three separate definitions of high risk of severe disease used in the UK (National Health Service Highest Risk, PANORAMIC trial eligibility, UK Health Security Agency Clinical Risk prioritisation for vaccination).

Results

Compared with national estimates, CPRD case estimates under-represented older adults in both the primary care (age 65–84: 6% in CPRD vs 9% nationally) and hospitalised (31% vs 40%) cohorts, and over-represented people living in regions with the highest median wealth areas of England (20% primary care and 20% hospital admitted cases in South East vs 15% nationally). The majority of non-hospitalised cases and all hospitalised cases had not completed primary series vaccination. In primary care, persons meeting high-risk definitions were older, more often smokers, overweight or obese, and had higher Charlson Comorbidity Index score.

Conclusions

CPRD primary care data are a robust real-world data source and can be used for some COVID-19 research questions, however, limitations of the data availability should be carefully considered. Included in this publication are supplemental files for a total of over 28 000 codes to define each of three definitions of high risk of severe disease.

Cost and utilization analysis of concurrent versus staged testicular prosthesis implantation for radical orchiectomy

by Vi Nguyen, Arman Walia, Joshua J. Horns, Niraj Paudel, Aditya Bagrodia, Darshan P. Patel, Tung-Chin Hsieh, James M. Hotaling

Purpose

American Urological Association guidelines recommend testicular prosthesis discussion prior to orchiectomy. Utilization may be low. We compared outcomes and care utilization between concurrent implant (CI) and staged implant (SI) insertion after radical orchiectomy.

Materials & methods

The MarketScan Commercial claims database (2008–2017) was queried for men ages >18 years who underwent radical orchiectomy for testicular mass, stratified as orchiectomy with no implant, CI, or SI. 90-day outcomes included rate of reoperation, readmission, emergency department (ED) presentation, and outpatient visits. Regression models provided rate ratio comparison.

Results

8803 patients (8564 no implant, 190 CI, 49 SI; 2.7% implant rate) were identified with no difference in age, Charlson Comorbidity Index, insurance plan, additional cancer treatment, or metastasis. Median perioperative cost at orchiectomy (+/- implant) for no implant, CI, and SI were $5682 (3648–8554), $7823 (5403–10973), and $5380 (4130–10521), respectively (p Conclusions

CI placement has less total perioperative cost, lower explant rate, and similar postoperative utilization to SI.

Avoidance of healthcare service use and correlates among HIV-positive patients in Vietnam: a cross-sectional study

Por: Nguyen · H. L. T. · Bui · T. M. · Dam · V. A. T. · Nguyen · T. T. · Nguyen · H. T. · Zeng · G. M. · Bradley · D. · Nguyen · Q. N. · Ngo · T. V. · Latkin · C. A. · Ho · R. C. · Ho · C. S.
Objective

The prevention of HIV/AIDS is not making sufficient progress. The slow reduction of HIV/AIDS infections needs to prioritise hesitancy towards service utilisation, including treatment duration, social support and social stigma. This study investigates HIV-positive patients’ avoidance of healthcare services and its correlates.

Design

A cross-sectional study.

Setting

The secondary data analysis used cross-sectional data from a randomised controlled intervention, examining the effectiveness of HIV-assisted smartphone applications in the treatment of HIV/AIDS patients in the Bach Mai and Ha Dong clinics in Hanoi.

Methods

Simple random sampling was used to identify 495 eligible patients. Two-tailed 2, Mann-Whitney, multivariate logistic and ordered logistic regression models were performed.

Primary and secondary outcome measures

The main study outcome was the patients’ healthcare avoidance and frequency of healthcare avoidance. The association of individual characteristics, social and behavioural determinants of HIV patients’ usage of health services was also determined based on the collected data using structured questionnaires.

Results

Nearly half of the participants avoid health service use (47.3%), while 30.7% rarely avoid health service use. Duration of antiretroviral therapy and initial CD4 cell count were negatively associated with avoidance of health services and frequency of health service avoidance. Similarly, those with the middle and highest income were more likely to avoid health services compared with those with the lowest income. People having health problems avoided health service use more frequently (OR 1.47, 95% CI 1.35 to 1.61).

Conclusions

Our study’s findings identify characteristics of significance in relation to health service avoidance and utilisation among HIV-positive patients. The results highlighted the need to improve satisfaction, adherence and utilisation of treatment. Moreover, identifying ways to address or incorporate those social determinants in new policy may also help the treatment of HIV/AIDS and strategically allocate funding in the changing financial and political climate of Vietnam.

Objectives

To quantify direct costs and healthcare resource utilisation (HCRU) associated with acute COVID-19 in adults in England.

Design

Population-based retrospective cohort study using Clinical Practice Research Datalink Aurum primary care electronic medical records linked to Hospital Episode Statistics secondary care administrative data.

Setting

Patients registered to primary care practices in England.

Population

1 706 368 adults with a positive SARS-CoV-2 PCR or antigen test from August 2020 to January 2022 were included; 13 105 within the hospitalised cohort indexed between August 2020 and March 2021, and 1 693 263 within the primary care cohort indexed between August 2020 and January 2022. Patients with a COVID-19-related hospitalisation within 84 days of a positive test were included in the hospitalised cohort.

Main outcome measures

Primary and secondary care HCRU and associated costs ≤4 weeks following positive COVID-19 test, stratified by age group, risk of severe COVID-19 and immunocompromised status.

Results

Among the hospitalised cohort, average length of stay, including critical care stays, was longer in older adults. Median healthcare cost per hospitalisation was higher in those aged 75–84 (£8942) and ≥85 years (£8835) than in those aged

Conclusions

COVID-19-related hospitalisations in older adults, particularly critical care stays, were the primary drivers of high COVID-19 resource use in England. These findings may inform health policy decisions and resource allocation in the prevention and management of COVID-19.

Behavioural and social drivers of COVID-19 vaccination in Vietnam: a scoping review

Por: Tran · L. · Dang · T. · Nguyen · M. · Kaufman · J. · Overmars · I. · Shrestha · S. · Abdi · I. · Nguyen · T. · Marahajan · M. · Chu · T. · Danchin · M. · Fox · G. · Nguyen · T. A.
Background

Understanding of the behavioural and social drivers (BeSD) of vaccination is key to addressing vaccine hesitancy and accessibility issues. Vietnam’s national COVID-19 vaccination programme resulted in high uptake of primary doses among adults, but lower booster doses for adults and primary doses for 5–11 years. This scoping review assessed BeSD influencing COVID-19 vaccine uptake in Vietnam to design interventions on reaching the national vaccination targets.

Method

We conducted a scoping review by searching PubMed, MedRxiv, LitCOVID, COVID-19 LOVE platform, WHO’s COVID-19 research database and seven dominant Vietnamese language medical journals published in English or Vietnamese between 28 December 2019 and 28 November 2022. Data were narratively synthesised and summarised according to the four components of the WHO BeSD framework. The drivers were then mapped along the timeline of COVID-19 vaccine deployment and the evolution of the pandemic in Vietnam.

Results

We identified 680 records, of which 39 met the inclusion criteria comprising 224 204 participants. Adults’ intention to receive COVID-19 vaccines for themselves (23 studies) ranged from 58.0% to 98.1%. Parental intention to vaccinate their under 11-year-old children (six studies) ranged from 32.8% to 79.6%. Key drivers of vaccination uptake were perceived susceptibility and severity of disease, perceived vaccine benefits and safety, healthcare worker recommendation, and positive societal perception. Commonly reported COVID-19 vaccines’ information sources (six studies) were social and mainstream media (82%–67%), television (72.7%–51.6%) and healthcare workers (47.5%–17.5%). Key drivers of COVID-19 uptake remained consistent for both adults and children despite changes in community transmission and vaccine deployment.

Conclusion

Key enablers of vaccine uptake for adults and children included perceived disease severity, perceived vaccine benefits and safety and healthcare worker recommendations. Future studies should assess vaccine communication targeted to these drivers, national policies and political determinants to optimise vaccine uptake.

Factors associated with intention to breastfeed in Vietnamese mothers: A cross-sectional study

by Duong Thi Thuy Doan, Colin Binns, Andy Lee, Yun Zhao, Minh Ngoc Pham, Hoa Thi Phuong Dinh, Chuong Canh Nguyen, Ha Thi Thu Bui

Introduction

Breastfeeding has many benefits for mothers, children, and the environment over both the short and longr-term. Prenatal intention to breastfeed is a powerful predictor of short-term breastfeeding outcomes.

Objective

This study aims to analyze breastfeeding intentions, including the intention to feed infants with breastmilk only and to continue exclusive breastfeeding to 6 months among pregnant mothers in Hanoi, Vietnam.

Methods

The analysis included 1230 singleton mothers, between 24- and 36-weeks’ gestation, who attended antenatal clinics in two hospitals in Hanoi in 2020.

Results

The proportion of mothers with an “breastfeeding intention” (i.e., intention to feed an infant with breastmilk only) and “exclusive breastfeeding intention” to 6 months was 59.9% and 41.7%, respectively. Mothers who were 25 years or older (aOR = 1.35, 95%CI:1.00–1.81), had an undergraduate educational degree or higher (aOR = 1.38, 95%CI: 1.08–1.76), had observed another woman breastfeeding (aOR = 1.43, 95%CI: 1.03–2.00), were not living with parents-in-law (aOR = 1.34, CI: 1.05–1.70), and were multiparous (aOR = 1.60, 95%CI: 1.16–2.19) had higher odds of “exclusive breastfeeding intention” to 6 months. Among primiparous women, those who thought their husbands support breastfeeding were more likely to intend to feed an infant with breastmilk only. Among multiparous women, feeding the previous child with breastmilk exclusively before the introduction of complementary foods and not giving solid foods together with water until 6 months, were significant predictors for both breastfeeding intentions.

Conclusion

Mothers without exclusive breastfeeding experience should be provided with greater support to promote exclusive breastfeeding intention and outcomes.

mHealth application for improving treatment outcomes for patients with multidrug-resistant tuberculosis in Vietnam: an economic evaluation protocol for the V-SMART trial

Por: Cheng · Q. · Dang · T. · Nguyen · T.-A. · Velen · K. · Nguyen · V. N. · Nguyen · B. H. · Vu · D. H. · Long · C. H. · Do · T. T. · Vu · T.-M. · Marks · G. B. · Yapa · M. · Fox · G. J. · Wiseman · V.
Introduction

The Strengthen the Management of Multidrug-Resistant Tuberculosis in Vietnam (V-SMART) trial is a randomised controlled trial of using mobile health (mHealth) technologies to improve adherence to medications and management of adverse events (AEs) in people with multidrug-resistant tuberculosis (MDR-TB) undergoing treatment in Vietnam. This economic evaluation seeks to quantify the cost-effectiveness of this mHealth intervention from a healthcare provider and societal perspective.

Methods and analysis

The V-SMART trial will recruit 902 patients treated for MDR-TB across seven participating provinces in Vietnam. Participants in both intervention and control groups will receive standard community-based therapy for MDR-TB. Participants in the intervention group will also have a purpose-designed App installed on their smartphones to report AEs to health workers and to facilitate timely management of AEs. This economic evaluation will compare the costs and health outcomes between the intervention group (mHealth) and the control group (standard of care). Costs associated with delivering the intervention and health service utilisation will be recorded, as well as patient out-of-pocket costs. The health-related quality of life (HRQoL) of study participants will be captured using the 36-Item Short Form Survey (SF-36) questionnaire and used to calculate quality-adjusted life-years (QALYs). Incremental cost-effectiveness ratios (ICERs) will be based on the primary outcome (proportion of patients with treatment success after 24 months) and QALYs gained. Sensitivity analysis will be conducted to test the robustness of the ICERs. A budget impact analysis will be conducted from a payer perspective to provide an estimate of the total budget required to scale-up delivery of the intervention.

Ethics and dissemination

Ethical approval for the study was granted by the University of Sydney Human Research Ethics Committee (2019/676), the Scientific Committee of the Ministry of Science and Technology, Vietnam (08/QD-HDQL-NAFOSTED) and the Institutional Review Board of the National Lung Hospital, Vietnam (13/19/CT-HDDD). Study findings will be published in peer-reviewed journals and conference proceedings.

Introduction

The Core Outcome Measures for Improving Care (COM-IC) project aims to deliver practical recommendations on the selection and implementation of a suite of core outcomes to measure the effectiveness of interventions for dementia care.

Methods and analysis

COM-IC embeds a participatory action approach to using the Alignment–Harmonisation–Results framework for measuring dementia care in Australia. Using this framework, suitable core outcome measures will be identified, analysed, implemented and audited. The methods for analysing each stage will be codesigned with stakeholders, through the conduit of a Stakeholder Reference Group including people living with dementia, formal and informal carers, aged care industry representatives, researchers, clinicians and policy actors. The codesigned evaluation methods consider two key factors: feasibility and acceptability. These considerations will be tested during a 6-month feasibility study embedded in aged care industry partner organisations.

Ethics and dissemination

COM-IC has received ethical approval from The University of Queensland (HREC 2021/HE001932). Results will be disseminated through networks established over the project, and in accordance with both the publication schedule and requests from the Stakeholder Reference Group. Full access to publications and reports will be made available through UQ eSpace (https://espace.library.uq.edu.au/), an open access repository hosted by The University of Queensland.

Vocal tasks for acoustic and/or auditory perceptual analysis for discriminating individuals with and without voice disorders: a systematic review protocol

Por: Gunjawate · D. R. · Chacon · A. M. · Nguyen · D. D. · Madill · C.
Objective

The primary objective of the present systematic review is to: (1) identify the current vocal tasks being used for acoustic and/or auditory perceptual analysis to differentiate between individuals with and without voice disorders. The secondary objectives are to: (2) evaluate the evidence of the sensitivity, specificity and accuracy of those vocal tasks for acoustic and/or auditory perceptual analysis in discriminating the individuals with voice disorders from those without; and (3) compare the values between the vocal tasks in discriminating individuals with voice disorders from those without.

Method and analysis

We search the following electronic databases: MEDLINE, EMBASE, CINAHL, Scopus, Web of Science Core Collection, PubMed Central and Google Scholar. Grey literature searches will include ProQuest Dissertations and Theses, ClinicalTrials.gov and the Cochrane Register of Controlled Trials. Websites of professional organisations and textbooks will be hand searched for relevant information related to the research question. Study screening, selection and data extraction will be conducted independently by two reviewers. Any disagreements will be resolved by discussion or by involving a third reviewer.

Inflammatory Markers and Fatigue in Individuals With Moderate to Severe Chronic Obstructive Pulmonary Disease

imageBackground Fatigue, a prevalent complex symptom among patients with chronic obstructive pulmonary disease (COPD), is considered an important clinical indicator of disease severity. However, the underlying mechanisms of COPD-related fatigue are not fully understood. Objectives This analysis explored the relationships between peripheral inflammatory markers and COPD-related fatigue in people with moderate to severe COPD. Methods This is a secondary analysis of a longitudinal observational study of individuals with COPD examining the biological causes and functional consequences of depression. The data used in this study were collected at baseline. Systemic inflammation markers included C-reactive protein (CRP) and three pro-inflammatory cytokines consisting of interleukin-6 (IL-6), IL-8, and tumor necrosis factor-α. COPD-related fatigue was self-reported using the Chronic Respiratory Questionnaire. Covariates included age; gender; smoking status; disease severity; symptoms of depression, anxiety, and pain; and social support. Multivariable linear regression analyses were conducted. Results The sample included 300 adults living with COPD; 80% were male, and the average age was 67.6 years. Modest correlations were found between two systemic inflammatory markers (CRP and IL-8) and COPD-related fatigue. CRP was the only inflammatory marker significantly associated with fatigue symptoms after adjusting for covariates in multivariable analyses. Depression, pain, and education level were also significant predictors of COPD-related fatigue. Discussion The findings suggest that altered immune response based on CRP may contribute to COPD-related fatigue. Management of depression and pain may work as an effective treatment strategy for COPD-related fatigue. Further longitudinal studies with a broader range of inflammatory markers and multidimensional measures of fatigue symptoms are warranted.

Early offering transcatheter aortic valve replacement to patients with moderate aortic stenosis: quantifying costs and benefits - a Markov model-based simulation study

Por: Nguyen · D. · Marwick · T. · Moodie · M. · Gao · L.
Objective

Aortic stenosis (AS) is one of the most common acquired cardiac valvular diseases. The success of transcatheter aortic valve implantation (TAVI) for severe AS has led to increasing interest in its use to earlier disease—moderate AS (MAS).

Design

Model-based study using a Markov microsimulation technique to evaluate the long-term costs and benefits associated with ‘early’ TAVI. Key data inputs were sourced from the international literature and costs were obtained from Australian sources.

Setting

Australian health care system perspective.

Participants

10 000 hypothetical MAS patients with or without left ventricular diastolic dysfunction or impaired left ventricular ejection fraction.

Intervention

Comparing early TAVI to medical management over a life time horizon for MAS patients aged >65 years. We evaluated the cost-effectiveness of offering early TAVI in five scenarios (10%, 25%, 50%, 75% and 90% take-up rates).

Primary and secondary outcome measures

The primary outcome measure is quality-adjusted life years (QALY) gained and the incremental cost–utility ratio (ICUR). Secondary outcomes are life-years gained and the number of heart failure case avoided.

Results

Offering early TAVI for MAS patients resulted in both higher healthcare costs and greater benefits (an increase of 3.02 QALYs or 3.99 life-years) per person treated. The ICUR was around $A10 867 and $A11 926 per QALY gained for all five scenarios, with the total cost of early TAVI to the healthcare system being anticipated to be up to $A3.66 billion. Sensitivity analyses indicated a 100% probability of being cost-effective with a willingness to pay threshold of $A50 000/QALY. The benefits remained, even with assumptions of high levels of repeat valve replacement after TAVI.

Conclusion

While ongoing randomised controlled trials will define the benefit of TAVI to MAS patients, these results suggest that this intervention is likely to be cost-effective.

Intrapartum care measures and indicators for monitoring the implementation of WHO recommendations for a positive childbirth experience: a scoping review

Objective

We aimed to identify all available studies describing measures or indicators used to monitor 41 intrapartum care practices described in the 2018 WHO intrapartum care recommendations, with a view to informing development of standardised measurement of implementing these recommendations.

Design

Systematic scoping review.

Methods

We conducted a scoping review to identify studies reporting measures of intrapartum care published between 1 January 2000 and 28 June 2021. Primary and secondary outcome measures included study characteristics (publication year, journal, country and World Bank classification) and intrapartum care measure characteristics (definition, numerator, denominator, measurement level and measurement approach). We searched MEDLINE, EMBASE, CINAHL, Cochrane Library, the Maternity and Infant Care Database, Global Index Medicus and grey literature using structured search terms related to included recommendations, focusing on respectful and supportive care, and clinical practices performed throughout labour and birth. The measures identified were classified by the WHO recommendation and their characteristics reported.

Results

We identified 150 studies which described 1331 intrapartum care measures. These measures corresponded to 35 of the 41 included WHO recommendations, and represented all domains of the WHO recommendations (care throughout labour and birth, first stage of labour, second stage of labour, third stage of labour). A total of 40.1% (534 of 1331 measures) of measures were related to respectful maternity care. Most studies used a questionnaire or survey measurement approach (522 of 1331 measures, 39.2%).

Conclusion

This scoping review presents a database of existing intrapartum care measures used to monitor the quality of intrapartum care globally. There is no clear consensus on a core set of measures for evaluating the practice of the WHO’s intrapartum care recommendations. This review provides a foundation to support the development of a core set of internationally standardised intrapartum care measures for the WHO intrapartum care recommendations, highlighting key areas requiring consensus and validation, and measure development.

Consecutive treatments of methamphetamine promote the development of cardiac pathological symptoms in zebrafish

Chronic methamphetamine use, a widespread drug epidemic, has been associated with cardiac morphological and electrical remodeling, leading to the development of numerous cardiovascular diseases. While methamphetamine has been documented to induce arrhythmia, most results originate from clinical trials from users who experienced different durations of methamphetamine abuse, providing no documentation on the use of methamphetamine in standardized settings. Additionally, the underlying molecular mechanism on how methamphetamine affects the cardiovascular system remains elusive. A relationship was sought between cardiotoxicity and arrhythmia with associated methamphetamine abuse in zebrafish to identify and to understand the adverse cardiac symptoms associated with methamphetamine. Zebrafish were first treated with methamphetamine 3 times a week over a 2-week duration. Immediately after treatment, zebrafish underwent electrocardiogram (ECG) measurement using an in-house developed acquisition system for electrophysiological analysis. Subsequent analyses of cAMP expression and Ca2+ regulation in zebrafish cardiomyocytes were conducted. cAMP is vital to development of myocardial fibrosis and arrhythmia, prominent symptoms in the development of cardiovascular diseases. Ca2+ dysregulation is also a factor in inducing arrhythmias. During the first week of treatment, zebrafish that were administered with methamphetamine displayed a decrease in heart rate, which persisted throughout the second week and remained significantly lower than the heart rate of untreated fish. Results also indicate an increased heart rate variability during the early stage of treatment followed by a decrease in the late stage for methamphetamine-treated fish over the duration of the experiment, suggesting a biphasic response to methamphetamine exposure. Methamphetamine-treated fish also exhibited reduced QTc intervals throughout the experiment. Results from the cAMP and Ca2+ assays demonstrate that cAMP was upregulated and Ca2+ was dysregulated in response to methamphetamine treatment. Collagenic assays indicated significant fibrotic response to methamphetamine treatment. These results provide potential insight into the role of methamphetamine in the development of fibrosis and arrhythmia due to downstream effectors of cAMP.

Impact of a short online course on the accuracy of non-ophthalmic diabetic retinopathy graders in recognising glaucomatous optic nerves in Vietnam

Por: Olawoye · O. O. · Ha · T. H. · Pham · N. · Nguyen · L. · Cherwek · D. H. · Fowobaje · K. R. · Ross · C. · Coote · M. · Chan · V. F. · Kahook · M. · Peto · T. · Azuara-Blanco · A. · Congdon · N.
Purpose

To test an online training course for non-ophthalmic diabetic retinopathy (DR) graders for recognition of glaucomatous optic nerves in Vietnam.

Methods

This was an uncontrolled, experimental, before-and-after study in which 43 non-ophthalmic DR graders underwent baseline testing on a standard image set, completed a self-paced, online training course and were retested using the same photographs presented randomly. Twenty-nine local ophthalmologists completed the same test without the training course. DR graders then underwent additional one–to-one training by a glaucoma specialist and were retested. Test performance (% correct, compared with consensus grades from four fellowship-trained glaucoma experts), sensitivity, specificity, positive and negative predictive value, and area under the receiver operating (AUC) curve, were computed.

Results

Mean age of DR graders (32.6±5.5 years) did not differ from ophthalmologists (32.3±7.3 years, p=0.13). Online training required a mean of 297.9 (SD 144.6) minutes. Graders’ mean baseline score (33.3%±14.3%) improved significantly after training (55.8%±12.6%, p

Conclusion

Non-ophthalmic DR graders can be trained to recognise glaucoma using a short online course in this setting, with no additional benefit from more expensive one–to-one training. After 5-hour online training in recognising glaucomatous optic nerve head, scores of non-ophthalmic DR graders doubled, and did not differ from local ophthalmologists. Intensive one-to-one training did not further improve performance
