Por: Naserrudin · N. A. · Adhikari · B. · Culleton · R. · Hod · R. · Saffree Jeffree · M. · Ahmed · K. · Hassan · M. R.
Introduction

Vector borne diseases (VBDs) present significant public health challenges in Southeast Asia (SEA), and the increasing number of cases threatens vulnerable communities. Inadequate vector control and management have been linked to the spread of VBDs. To address these issues, community participation has been proposed as a promising approach to enhance health programmes and control of VBDs. This article outlines a protocol for a scoping review of the published literature on community-participation approaches to control VBDs in the SEA region. The primary research question is ‘How does community participation complement the control of VBDs in SEA?’ This review aims to provide an overview of various approaches and identify barriers and facilitators to effective implementation.

Methods and analysis

The research questions will guide the scoping review. In stage 1, peer-reviewed publications from PubMed, Web of Science and Scopus will be searched using predefined search terms related to community-based approaches and VBDs in the SEA region, English, Indonesian and Malay published between 2012 and 2022. In stage 2, the references from relevant articles will be screened for eligibility. In stage 3, eligible articles will be charted in Microsoft Excel to facilitate the review process, and studies will be characterised based on the investigated diseases; this review will also highlight the methodological context of these studies. In stage 4, a thematic analysis will be conducted to derive meaningful findings from the dataset relevant to the research inquiry, followed by writing the results in stage 5. This scoping review aims to be the first to explore community participation in VBD control in the SEA population, providing valuable insights for future research and stakeholders involved in disease control.

Ethics and dissemination

This scoping review does not require ethical approval because the methodology synthesises information from available articles. This review is planned for dissemination in academic journals, conference presentations and shared with stakeholders as part of knowledge sharing among those involved in VBD control.

Projecting non-communicable diseases attributable to air pollution in the climate change era: a systematic review

Por: Karim · N. · Hod · R. · Wahab · M. I. A. · Ahmad · N.
Objectives

Climate change is a major global issue with significant consequences, including effects on air quality and human well-being. This review investigated the projection of non-communicable diseases (NCDs) attributable to air pollution under different climate change scenarios.

Design

This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 flow checklist. A population-exposure-outcome framework was established. Population referred to the general global population of all ages, the exposure of interest was air pollution and its projection, and the outcome was the occurrence of NCDs attributable to air pollution and burden of disease (BoD) based on the health indices of mortality, morbidity, disability-adjusted life years, years of life lost and years lived with disability.

Data sources

The Web of Science, Ovid MEDLINE and EBSCOhost databases were searched for articles published from 2005 to 2023.

Eligibility criteria for selecting studies

The eligible articles were evaluated using the modified scale of a checklist for assessing the quality of ecological studies.

Data extraction and synthesis

Two reviewers searched, screened and selected the included studies independently using standardised methods. The risk of bias was assessed using the modified scale of a checklist for ecological studies. The results were summarised based on the projection of the BoD of NCDs attributable to air pollution.

Results

This review included 11 studies from various countries. Most studies specifically investigated various air pollutants, specifically particulate matter 2.5), nitrogen oxides and ozone. The studies used coupled-air quality and climate modelling approaches, and mainly projected health effects using the concentration–response function model. The NCDs attributable to air pollution included cardiovascular disease (CVD), respiratory disease, stroke, ischaemic heart disease, coronary heart disease and lower respiratory infections. Notably, the BoD of NCDs attributable to air pollution was projected to decrease in a scenario that promotes reduced air pollution, carbon emissions and land use and sustainable socioeconomics. Contrastingly, the BoD of NCDs was projected to increase in a scenario involving increasing population numbers, social deprivation and an ageing population.

Conclusion

The included studies widely reported increased premature mortality, CVD and respiratory disease attributable to PM2.5. Future NCD projection studies should consider emission and population changes in projecting the BoD of NCDs attributable to air pollution in the climate change era.

Effectiveness and cost-effectiveness of a 12-month automated text message intervention for weight management in postpartum women with overweight or obesity: protocol for the Supporting MumS (SMS) multisite, parallel-group, randomised controlled trial

Por: Gallagher · D. · Spyreli · E. · Anderson · A. S. · Bridges · S. · Cardwell · C. R. · Coulman · E. · Dombrowski · S. U. · Free · C. · Heaney · S. · Hoddinott · P. · Kee · F. · McDowell · C. · McIntosh · E. · Woodside · J. V. · McKinley · M. C.
Introduction

The reproductive years can increase women’s weight-related risk. Evidence for effective postpartum weight management interventions is lacking and engaging women during this life stage is challenging. Following a promising pilot evaluation of the Supporting MumS intervention, we assess if theory-based and bidirectional text messages to support diet and physical activity behaviour change for weight loss and weight loss maintenance, are effective and cost-effective for weight change in postpartum women with overweight or obesity, compared with an active control arm receiving text messages on child health and development.

Methods and analysis

Two-arm, parallel-group, assessor-blind randomised controlled trial with cost-effectiveness and process evaluations. Women (n=888) with body mass index (BMI) ≥25 kg/m2 and within 24 months of giving birth were recruited via community and National Health Service pathways through five UK sites targeting areas of ethnic and socioeconomic diversity. Women were 1:1 randomised to the intervention or active control groups, each receiving automated text messages for 12 months. Data are collected at 0, 6, 12 and 24 months. The primary outcome is weight change at 12 months from baseline, compared between groups. Secondary outcomes include weight change (24 months) and waist circumference (cm), proportional weight gain (>5 kg), BMI (kg/m2), dietary intake, physical activity, infant feeding and mental health (6, 12 and 24 months, respectively). Economic evaluation examines health service usage and personal expenditure, health-related quality of life and capability well-being to assess cost-effectiveness over the trial and modelled lifetime. Cost–utility analysis examines cost per quality-adjusted life-years gained over 24 months. Mixed-method process evaluation explores participants’ experiences and contextual factors impacting outcomes and implementation. Stakeholder interviews examine scale-up and implementation.

Ethics and dissemination

Ethical approval was obtained before data collection (West of Scotland Research Ethics Service Research Ethics Committee (REC) 4 22/WS/0003). Results will be published via a range of outputs and audiences.

Trial registration number

ISRCTN16299220.

A scoping review of the role of policy in mitigating childhood obesity in underserved populations using the RE‐AIM framework

Abstract

Background

Childhood obesity is an escalating crisis in the United States. Health policy may impact this epidemic which disproportionally affects underserved populations.

Aim

The aim was to use the reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) framework to assess health policy impact on preventing or treating school-aged children (5 > 18 years) with obesity in underserved populations.

Methods

A scoping review of 842 articles was conducted. Twenty-four articles met the inclusion criteria and underwent data extraction.

Results

Twelve studies included subgroup analysis, with four suggesting an impact of policy on at-risk groups. None of the 24 studies fully applied the RE-AIM framework. Policies positively impacted childhood obesity in 12 studies across the sample.

Linking Evidence to Action

Our review revealed inconsistent evidence for the effectiveness of policy on childhood obesity, perhaps due to the lack of focus on the social determinants of health. In addition, many studies did not evaluate the outcomes for underserved populations. Therefore, we propose more attention to social determinants in future legislation and evaluation of policy effectiveness on underserved populations. Findings identify an urgent need for the design, implementation, and evaluation of policies specifically directed to address the inequities of racism, social injustices, and social determinants of health that impact childhood obesity in the United States. Future work needs to identify who was reached by the policy, who benefitted from the policy, and how policies were implemented to address obesity-related health disparities. Nurses should advocate for the evaluation of childhood obesity policies, particularly in underserved populations, to determine effectiveness. Nurses, particularly those trained in population and community health and research, should advocate for policy research that considers inequities rather than controls for these variables. Multi-layered interventions can then be tailored to sub-populations and evaluated more effectively.

Exploring community behaviours and stakeholder challenges in engaging communities with dengue prevention behaviour in Malaysia: implementation research for a qualitative study with a community-based participatory research design

Por: Samsudin · N. A. · Karim · N. · Othman · H. · Naserrudin · N. A. · Sahani · M. · Hod · R. · Siau · C. S. · Harif · M. N. · Abd. Samad · B. H. · Zaini · Z.-I. I.
Objectives

To use a community-based participatory research (CBPR) design to explore local community behaviours and stakeholders’ challenges in engaging communities in dengue prevention behaviours in Hulu Langat, Selangor, Malaysia.

Design

This CBPR design in implementation comprised in-depth interviews (IDIs) and focus group discussions (FGDs). Themes were identified from the data with inductive and deductive thematic analysis.

Setting

FGDs were conducted in local community areas and IDIs were conducted in the local authority (LA) office and the Hulu Langat district health office.

Participants

All FGD and IDI participants consented to the study, and included health authorities (n=4), LAs (n=7), community leader (n=1), faith leader (n=1), patients diagnosed with dengue (IDIs, n=2) and permanent residents of Hulu Langat who had been exposed to dengue infectious disease (FGDs, n=27).

Results

The main themes were categorised into community behaviour and stakeholder challenges. The community behaviour-related themes were awareness of dengue disease and Aedes mosquitoes, perception of risk and severity, and involvement of authorities. The themes related to stakeholder challenges were resource constraints and capacity issues, jurisdictional constraints and coordination, and educational dissemination and vandalism.

Conclusions

The actions of the authorities shape community and stakeholder behaviours. Effective communication, including clear and aesthetically pleasing messages, motivates individuals to take appropriate actions. It is crucial for the authorities to engage in inclusive communication and consider diverse perspectives, such as those of residents and individuals exposed to dengue infection. Authorities that provide accurate and unbiased information foster transparency and enable informed decision-making by all stakeholders.

To highlight the value of utilizing the Listening Guide methodology for nursing research and provide an exemplar applying this methodology to explore a novel concept in an underrepresented group—inner strength in persons newly diagnosed with mild cognitive impairment along with their care partners.

Design

Methodology discussion paper.

Methods

The exemplar study used the Listening Guide methods for data elicitation and analysis. Methods included adaptations for the study population and novice qualitative researchers.

Results

The Listening Guide methodology with adaptations enabled the research team to centre the voices of persons living with mild cognitive impairment, highlight an abstract phenomenon and attend to the influences of the sociopolitical context. Further, this methodology helped address common challenges emerging qualitative researchers encounter, including understanding methods of application, engaging reflexively and immersing in the data.

Conclusion

The Listening Guide is a voice-centred qualitative methodology that is well suited to foreground the experiences of groups underrepresented in research and explore emerging phenomena.

Implications for Nursing

Nurses are central to striving for health equity. The Listening Guide methodology offers a valuable and accessible research tool to understand the experiences and needs of underrepresented groups and shape healthcare in response.

Impact

The Listening Guide methodology can be broadly applied to research with persons with mild cognitive impairment, and other underrepresented groups, to explore other phenomena beyond inner strength and move the science forward in representing the perspectives of groups underrepresented by research.

Patient or Public Contribution

Persons living with cognitive impairment and their care partners participated in study conceptualization, interview guide development, methods development and dissemination plans.

Enhanced active case finding of drug-resistant tuberculosis in Namibia: a protocol for the hotspots, hospitals, and households (H3TB) study

Por: Shavuka · O. · Iipumbu · E. · Boois · L. · Günther · G. · Hoddinott · G. · Lin · H.-H. · Nepolo · E. · Niemann · S. · Ruswa · N. · Seddon · J. · Claassens · M. M.
Introduction

Namibia is a high tuberculosis (TB)-burden country with an estimated incidence of 460/100 000 (around 12 000 cases) per year. Approximately 4.5% of new cases and 7.9% of previously treated TB cases are multidrug resistant (MDR) and 47% of patients with MDR-TB are HIV coinfected. Published data suggest a clustering of MDR-TB transmission in specific areas. Identifying transmission clusters is key to implementing high-yield and cost-effective interventions. This includes knowing the yield of finding TB cases in high-transmission zones (eg, community hotspots, hospitals or households) to deliver community-based interventions. We aim to identify such transmission zones for enhanced case finding and evaluate the effectiveness of this approach.

Methods and analysis

H3TB is an observational cross-sectional study evaluating MDR-TB active case finding strategies. Sputum samples from MDR-TB cases in three regions of Namibia will be evaluated by whole genome sequencing (WGS) in addition to routine sputum investigations (Xpert MTB/RIF, culture and drug susceptibility testing). We will collect information on household contacts, use of community spaces and geographical map intersections between participants, synthesising these data to identify transmission hotspots. We will look at the feasibility, acceptability, yield and cost of case finding strategies in these hotspots, and in households of patients with MDR-TB and visitors of hospitalised patients with MDR-TB. A compartmental transmission dynamic model will be constructed to evaluate the impact and cost-effectiveness of the strategies if scaled.

Ethics and dissemination

Ethics approval was obtained. Participants will give informed consent. H3TB will capitalise on a partnership with the Ministry of Health and Social Services to follow up individuals diagnosed with MDR-TB and integrate WGS data with innovative contact network mapping, to allow enhanced case finding. Study data will contribute towards a systems approach to TB control. Equally important, it will serve as a role model for similar studies in other high-incidence settings.

Por: Rezaianzadeh · A. · Niazkar · H. R. · Rezaeianzadeh · R. · Jafari · F. · Rahimikazerooni · S. · Ghoddusi Johari · M. · Zare · M. · Hosseini · S. V.
Purpose

The Kharameh cohort study (KHCS) is one branch of the ‘Prospective Epidemiological Research Studies in Iran’, located in the south of Iran. The enrolment phase of KHCS spanned from April 2015 to March 2017, during which urban and rural residents of Kharameh were enrolled in the study. KHCS aims to investigate the incidence of non-communicable diseases (NCDs) such as hypertension, diabetes mellitus, cardiovascular diseases and cancer, and its related risk factors in a 15-year follow-up.

Participants

KHCS was designed to recruit 10 000 individuals aged 40–70 years old from both urban and rural areas of Kharameh. Thus, a total of 10 800 individuals aged 40–70 years of age were invited and, finally, 10 663 subjects were accepted to participate, with a participation rate of 98.7%.

Findings to date

Of the 10 663 participants, 5944 (55.7%) were women, and 6801 (63.7%) were rural residents. The mean age of the participants was 51.9±8.2 years. 41.8% of the participants were aged 40–49, 35.2% were aged 50–59 and the remaining 23% were 60–70 years old. Until March 2020 (first 3 years of follow-up), the total number of patients diagnosed with NCDs was 1565. Hypertension, type 2 diabetes and acute ischaemic heart disease were the most common NCDs. Furthermore, the total number of deaths during the first 3 years of follow-up was 312, with cardiovascular diseases (38.7%) as the most common cause of death, followed by cerebrovascular diseases (11.8%) and cancer (16.2%).

Future plans

The remaining 12 years of follow-up will inevitably shed light on the genetic, lifestyle/socioeconomic status, and environmental risk and protective factors of NCDs.

Development and psychometric properties evaluation of nurses innovative behaviours inventory in Iran: protocol for a sequential exploratory mixed-method study

Por: Shahidi Delshad · E. · Soleimani · M. · Zareiyan · A. · Ghods · A. A.
Introduction

Nurses’ innovative behaviours play a crucial role in addressing the challenges including adapting to emerging technologies, resource limitations and social realities such as population ageing that are intricately tied to today’s healthcare landscape. Innovative behaviours improve healthcare quality, patient safety and satisfaction. Organisational factors and individual attributes influence nurses’ inclination to innovate. With the rise of artificial intelligence and novel technology, healthcare institutions are actively engaged in the pursuit of identifying nurses who demonstrate innovative qualities. Developing a comprehensive protocol to elucidate the various dimensions of nurses’ innovative behaviours and constructing a valid measuring instrument, rooted in this protocol represents a significant step in operationalising this concept.

Methods and analysis

The study encompasses two phases: a qualitative study combined with a literature review, followed by the design and psychometric evaluation of the instrument. To ensure diversity, a maximum variation purposive sampling method will be used during the qualitative phase to select clinical nurses. In-depth semistructured interviews will be conducted and analysed using conventional content analysis. Additionally, a comprehensive literature review will supplement any missing features not captured in the qualitative phase, ensuring their inclusion in the primary tool. The subsequent quantitative phase will focus on evaluating the questionnaire’s psychometric properties, including face, content and construct validity through exploratory factor analyses (including at least 300 samples) and confirmatory factor analyses (including at least 200 samples). Internal consistency (Cronbach’s alpha), reliability (test–retest), responsiveness, interpretability and scoring will also be assessed.

Ethics and dissemination

This study originates from a doctoral dissertation in nursing. Permission and ethical approval from Semnan University of Medical Sciences has been obtained with reference code IR.SEMUMS.1401.226. The study’s findings will ultimately be submitted as a research paper to a peer-reviewed journal.

What are the views of adults with an intellectual disability (AWID), carers and healthcare professionals on a community falls management programme for AWID: a qualitative interview study in the UK

Por: Robinson · K. · Logan · P. · Tucker · C. · Finlayson · J. · van der Wardt · V. · Kilby · A. · Knowles · S. · Vanhegan · S. · Hodgson · S. · Lidstone · N.
Objectives

The aim of this study was to refine a draft of the ACTiON FALLS LD programme based on the views of adults with an intellectual disability (AWID), carers and healthcare professionals (HCPs).

Design, setting and participants

The semistructured interview study included HCP as well as AWID and carers supporting AWID living in the community. Community settings included sheltered living, supported living, AWID living at home with family carers or independently. The interview study explored the first draft of the ACTiON FALLS LD programme as well as the wider falls management for AWID. Interviews with AWID were developed to include a range of approaches (eg, case studies, pictures) to support inclusive participation. Individual interviews were digitally recorded and transcribed. Researcher notes were used during interviews with AWID. All data were analysed using the principles of framework analysis.

Results

14 HCP, 8 carers and 13 AWID took part in the interview process. Five key themes were identified: programme components, programme design, programme approach, who would use the programme and programme delivery.

Conclusions

The views of AWID, HCP and carers showed the need to consider the impact of risk perception, anxiety and fear of falling in the adaption of the ACTiON FALLS programme. The programme needs to be accessible and support the inclusion of AWID in managing falls and ultimately fulfil the requirement for a proactive and educational tool by all.

Factors that influence medication adherence in women with fibromyalgia: A path analysis

Abstract

Aims

To investigate the relationships between depression symptoms, perceived stigma, disease severity, patient-provider communication and medication adherence in fibromyalgia patients. The objectives were to explore how these factors influence treatment adherence and to develop a comprehensive model illustrating their interconnections.

Background

Fibromyalgia is a chronic pain syndrome with fatigue, sleep issues and idiopathic pain. Medication adherence is limited by insufficient symptom relief, side effects and costs. Stigma further complicates fibromyalgia. Disease severity affects patient-provider communication. Associations between depression, stigma, severity, communication and adherence in fibromyalgia are unclear.

Design

A cross-sectional, correlational study.

Methods

The STROBE guidelines for cross-sectional studies were followed. Participants included Hebrew-speaking participants who were members of two Facebook groups: ‘Shades of Purple’ and ‘Fibromyalgia- Get to Know!’ Between February and April 2022. They undertook evaluations using The Patient Health Questionnaire-9 to gauge depression symptoms, assessed perceived stigma, utilised The Revised Fibromyalgia Impact Questionnaire to determine disease severity, employed The Patient Reaction Assessment questionnaire for patient-provider communication, and used the 8-item Morisky Medication Adherence Scale (MMAS-8). Associations between the variables were explored using Pearson's correlations and path analyses.

Results

The study included 141 women with fibromyalgia, aged 22 to 76 years. Most reported having a stable partner (69.5%) and 75.2% had children. The treatment adherence levels were as follows: 53.2% (N = 75)—low, 33.3% (N = 47)—medium and 13.5% (N = 19)—high. Depression positively correlated with stigma. Stigma negatively correlated with patient-provider communication. Patient-provider communication positively correlated with treatment adherence. A significant negative indirect effect of depression on treatment adherence through stigma and patient-provider communication was found.

Conclusions

Perceived stigma and patient-provider communication played a mediating role in the relationships between depression and treatment adherence among women with fibromyalgia.

Relevance to Clinical Practice

Addressing stigma related to fibromyalgia and effective patient-provider communication can positively influence treatment adherence.

Application of in-silico drug discovery techniques to discover a novel hit for target-specific inhibition of SARS-CoV-2 Mpro’s revealed allosteric binding with MAO-B receptor: A theoretical study to find a cure for post-covid neurological disorder

by Magdi E. A. Zaki, Sami A. AL-Hussain, Aamal A. Al-Mutairi, Abdul Samad, Vijay H. Masand, Rahul G. Ingle, Vivek Digamber Rathod, Nikita Maruti Gaikwad, Summya Rashid, Pravin N. Khatale, Pramod V. Burakale, Rahul D. Jawarkar

Several studies have revealed that SARS-CoV-2 damages brain function and produces significant neurological disability. The SARS-CoV-2 coronavirus, which causes COVID-19, may infect the heart, kidneys, and brain. Recent research suggests that monoamine oxidase B (MAO-B) may be involved in metabolomics variations in delirium-prone individuals and severe SARS-CoV-2 infection. In light of this situation, we have employed a variety of computational to develop suitable QSAR model using PyDescriptor and genetic algorithm-multilinear regression (GA-MLR) models (R2 = 0.800–793, Q2LOO = 0.734–0.727, and so on) on the data set of 106 molecules whose anti-SARS-CoV-2 activity was empirically determined. QSAR models generated follow OECD standards and are predictive. QSAR model descriptors were also observed in x-ray-resolved structures. After developing a QSAR model, we did a QSAR-based virtual screening on an in-house database of 200 compounds and found a potential hit molecule. The new hit’s docking score (-8.208 kcal/mol) and PIC50 (7.85 M) demonstrated a significant affinity for SARS-CoV-2’s main protease. Based on post-covid neurodegenerative episodes in Alzheimer’s and Parkinson’s-like disorders and MAO-B’s role in neurodegeneration, the initially disclosed hit for the SARS-CoV-2 main protease was repurposed against the MAO-B receptor using receptor-based molecular docking, which yielded a docking score of -12.0 kcal/mol. This shows that the compound that inhibits SARS-CoV-2’s primary protease may bind allosterically to the MAO-B receptor. We then did molecular dynamic simulations and MMGBSA tests to confirm molecular docking analyses and quantify binding free energy. The drug-receptor complex was stable during the 150-ns MD simulation. The first computational effort to show in-silico inhibition of SARS-CoV-2 Mpro and allosteric interaction of novel inhibitors with MAO-B in post-covid neurodegenerative symptoms and other disorders. The current study seeks a novel compound that inhibits SAR’s COV-2 Mpro and perhaps binds MAO-B allosterically. Thus, this study will enable scientists design a new SARS-CoV-2 Mpro that inhibits the MAO-B receptor to treat post-covid neurological illness.

How do they cope? A national cross-sectional study of coping in hospital doctors in Ireland

Por: Doherty · A. · Prihodova · L. · Walsh · G. · Hayes · B.
Objectives

To measure coping strategies and associated psychological distress, burnout and work ability in hospital doctors in Ireland.

Design

National cross-sectional study of randomised sample of trainee and consultant hospital doctors.

Setting

Irish publicly funded hospitals and residential institutions.

Participants

1749 doctors returned surveys (55% response rate).

Outcome measures

Dependent variables were psychological distress (measured using 12-item General Health Questionnaire), burnout (Maslach Burnout Inventory) and work ability (single-item measure). Adaptive and maladaptive coping strategies (Brief Coping Orientation to Problems Experienced) were covariates.

Results

The coping mechanism most frequently reported by this cohort was the adaptive strategy of active planning. Increased mean hours worked (MHW) (OR 1.02; 95% CI 1.01 to 1.03), a low Work Ability Score (OR 3.23; 95% CI 2.47 to 4.23) and maladaptive coping strategies (OR 1.26; 95% CI 1.22 to 1.31) were significantly associated with psychological distress. Adaptive coping was associated with decreased psychological distress (OR 0.98; 95% CI 0.97 to 1.00). Increased MHW (OR 0.98; 95% CI 0.97 to 0.99), insufficient work ability (OR 0.62; 95% CI 0.48 to 0.80) and maladaptive coping (OR 0.87; 95% CI 0.85 to 0.89) were significantly associated with burnout. Increased MHW (OR 0.99; 95% CI 0.98 to 1.00) and maladaptive coping (OR 0.90, 95% CI 0.88 to 0.92) were significantly associated with insufficient work ability.

Conclusions

Adaptive coping is associated with decreased psychological distress but does not mitigate the effect of increased work hours, which are associated with burnout, distress and insufficient work ability, regardless of a doctor’s coping style. The burden of psychological distress on doctors cannot be mitigated meaningfully unless workplace factors are addressed.

Feasibility of a pregnancy intervention mimicking viral transmission mitigation measures on the incidence of preterm birth in high-risk pregnant women enrolled in antenatal clinics in Melbourne, Australia: protocol for a pilot, randomised trial

Por: Sridhar · S. · Mol · B. W. · Hodges · R. · Palmer · K. R. · Sundram · S. · de Carvalho Pacagnella · R. · Souza · R. T. · Barbosa-Junior · F. · Mackin · D. · Said · J. · Rolnik · D. · Malhotra · A.
Introduction

Preterm birth is a leading cause of perinatal morbidity and mortality. During the COVID-19 pandemic, reduction in rates of preterm birth in women exposed to viral mitigation measures was reported by multiple studies. In addition, others and we observed a more pronounced reduction of preterm birth in women who had previously experienced a preterm birth. The aim of this pilot study is to establish the feasibility of a lifestyle intervention based on viral mitigation measures in high-risk pregnancies, with the ultimate aim to reduce the incidence of preterm birth.

Methods and analysis

One hundred pregnant women, enrolled in antenatal clinics at two tertiary maternity centres in Melbourne, Australia, who have had a previous preterm birth between 22 and 34 weeks gestation will be recruited. This is a two-arm, parallel group, open-label randomised controlled feasibility trial: 50 women will be randomised to the intervention group, where they will be requested to comply with a set of lifestyle changes (similar to the viral mitigation measures observed during the pandemic). Another 50 women will be randomised to the control group, where they will undergo standard pregnancy care. The primary outcome of this trial is feasibility, which will be assessed by measuring patient eligibility rate, recruitment rate, compliance rate and data completion rate. Secondary outcomes include incidence of preterm birth, maternal satisfaction, maternal quality of life and other pregnancy outcomes. Standard methods in statistical analysis for randomised controlled trials on an intention to treat basis will be followed.

Ethics and dissemination

This trial has been approved by the Monash Human Research Ethics Committee; approval reference number RES-22-0000-122A. Study findings will be reported and submitted to peer-reviewed journals for publication, and presentation at conferences.

Heart Failure (HF) significantly impacts approximately 26 million people worldwide, causing disruptions in the normal functioning of their hearts. The estimation of left ventricular ejection fraction (LVEF) plays a crucial role in the diagnosis, risk stratification, treatment selection, and monitoring of heart failure. However, achieving a definitive assessment is challenging, necessitating the use of echocardiography. Electrocardiogram (ECG) is a relatively simple, quick to obtain, provides continuous monitoring of patient’s cardiac rhythm, and cost-effective procedure compared to echocardiography. In this study, we compare several regression models (support vector machine (SVM), extreme gradient boosting (XGBOOST), gaussian process regression (GPR) and decision tree) for the estimation of LVEF for three groups of HF patients at hourly intervals using 24-hour ECG recordings. Data from 303 HF patients with preserved, mid-range, or reduced LVEF were obtained from a multicentre cohort (American and Greek). ECG extracted features were used to train the different regression models in one-hour intervals. To enhance the best possible LVEF level estimations, hyperparameters tuning in nested loop approach was implemented (the outer loop divides the data into training and testing sets, while the inner loop further divides the training set into smaller sets for cross-validation). LVEF levels were best estimated using rational quadratic GPR and fine decision tree regression models with an average root mean square error (RMSE) of 3.83% and 3.42%, and correlation coefficients of 0.92 (p

A novel splice-site <i>FHOD3</i> founder variant is a common cause of hypertrophic cardiomyopathy in the population of the Balkans–A cohort study

Founder variants in sarcomere protein genes account for a significant proportion of disease-causing variants in patients with hypertrophic cardiomyopathy (HCM). However, information on founder variants in non-sarcomeric protein genes, such as FHOD3, which have only recently been associated with HCM, remains scarce. In this study, we conducted a retrospective analysis of exome sequencing data of 134 probands with HCM for recurrent pathogenic variants. We discovered a novel likely pathogenic variant c.1646+2T>C in FHOD3 in heterozygous state in eight probands with HCM and confirmed its presence in seven additional relatives. Individuals with this variant had a wide range of ages at onset of the disease (4–63 years). No adverse cardiac events were observed. Haplotype analysis revealed that the individuals with this variant shared a genomic region of approximately 5 Mbp surrounding the variant, confirming the founder effect of the variant. FHOD3 c.1646+2T>C is estimated to have arisen 58 generations ago (95% CI: 45–81) in a common ancestor living on the Balkans. A founder FHOD3 c.1646+2T>C variant is the second most common genetic variant in our cohort of patients with HCM, occurring in 16% of probands with a known genetic cause of HCM, which represents a substantially higher proportion than the currently estimated 0.5–2% for causal FHOD3 variants. Our study broadens the understanding of the genetic causes of HCM and may improve the diagnosis of this condition, particularly in patients from the Balkans.

Introduction

Breastfeeding has health benefits for infants and mothers, yet the UK has low rates with marked social inequalities. The Assets-based feeding help Before and After birth (ABA) feasibility study demonstrated the acceptability of a proactive, assets-based, woman-centred peer support intervention, inclusive of all feeding types, to mothers, peer supporters and maternity services. The ABA-feed study aims to assess the clinical and cost-effectiveness of the ABA-feed intervention compared with usual care in first-time mothers in a full trial.

Methods and analysis

A multicentre randomised controlled trial with economic evaluation to explore clinical and cost-effectiveness, and embedded process evaluation to explore differences in implementation between sites. We aim to recruit 2730 primiparous women, regardless of feeding intention. Women will be recruited at 17 sites from antenatal clinics and various remote methods including social media and invitations from midwives and health visitors. Women will be randomised at a ratio of 1.43:1 to receive either ABA-feed intervention or usual care. A train the trainer model will be used to train local Infant Feeding Coordinators to train existing peer supporters to become ‘infant feeding helpers’ in the ABA-feed intervention. Infant feeding outcomes will be collected at 3 days, and 8, 16 and 24 weeks postbirth. The primary outcome will be any breastfeeding at 8 weeks postbirth. Secondary outcomes will include breastfeeding initiation, any and exclusive breastfeeding, formula feeding practices, anxiety, social support and healthcare utilisation. All analyses will be based on the intention-to-treat principle.

Ethics and dissemination

The study protocol has been approved by the East of Scotland Research Ethics Committee. Trial results will be available through open-access publication in a peer-reviewed journal and presented at relevant meetings and conferences.
