Public involvement in mental health research enhances research quality. The use of citizen science methods in mental health research has been described as a conclusion of a movement towards increased public involvement; however, this field is in its early stages of development. Our objective was to create a theory of change (ToC) for how citizen science can be used to enhance mental health research quality.

Iterative consultation with the stakeholders of an existing citizen mental health science study, that is, change for citizen science to achieve co-production at scale (C-STACS: https://www.researchintorecovery.com/research/c-stacs/)

We co-developed a ToC through an iterative consultation with C-STACS stakeholders who were (a) representatives of mental health community organisations (n=10), individuals with public involvement experience (n=2) and researchers (n=5). In keeping with established ToC practice, entities were identified, including long-term impacts, outcomes needed to create an impact, stakeholder assumptions and indicators for tracking progress.

A desired primary long-term impact of greater co-production of research was identified between researchers and members of the public, which would create a secondary impact of enhancing public capacity to engage in citizen mental health science. We proposed long-term outcomes needed to enable this impact: (1) greater co-production of research objectives and pathways between researcher and the public, (2) greater embedment of citizen mental health science into funder processes (eg, the creation of specific funding calls for citizen mental health science proposals, (3) greater clarity on the boundaries between citizen science and other participatory approaches (eg, so that there is not loss of impact due to conceptual confusion between these, (4) increased knowledge around effective frameworks to enable mass public participation and (5) greater availability of technology platforms, enabling safe and accessible engagement with citizen mental health science projects.

The proposed ToC is grounded in the C-STACS project, but intended to be broadly applicable. It allows the continued formation of a community of practice around citizen mental health science and should be reviewed, as greater knowledge is developed on how citizen mental health science creates change.

Medical oxygen supplementation is essential for treating severe illnesses and plays a critical role in managing life-threatening conditions, especially during the period of increased demand, such as the delta wave of COVID-19. The study aims to evaluate oxygen requirements and production to support effective capacity planning for future health crises.

Cross-sectional quantitative study. Data collection was carried out between 15 March and 19 December 2021.

The study used secondary data from Nepal’s Health Emergency Operation Centre. Regarding medical oxygen production, calculations included oxygen generated from both hospital-based oxygen plants and private companies, using their highest capacities for comparison. These production capacities were then assessed using three levels of efficiency (100%, 80% and 50%), revealing significant gaps when compared against the oxygen requirements of hospitalised COVID-19 patients, as guided by WHO recommendations. The results were communicated in terms of J-size cylinders, alongside average daily COVID-19 hospitalizations. Data was inputted and analysed using Microsoft Excel and presented in numbers and percentage.

The country’s oxygen demand relies largely on the production from private enterprises, with meeting approximately 85.2% of the total requirement. Optimal production ensures that national oxygen needs will be met. The analysis highlighted that at 80% operational efficiency, 90.8% of the hospital’s requirements could be fulfilled. However, if operational efficiency drops to 50%, the fulfilment rate diminishes to 56.7%. The differences in requirement and production of oxygen are consistent across the provinces; however, a huge disparity was notable in Karnali and Sudurpaschim.

Continuous assessment of production capacities in both hospital and private enterprises producing oxygen is necessary to plan and address the gaps.

This study aimed to evaluate the cost-effectiveness of integrating nutritional support into India’s National Tuberculosis Elimination Programme (NTEP) using the MUKTI initiative.

Economic evaluation.

Primary data on the cost of delivering healthcare services, out-of-pocket expenditure and health-related quality of life among patients with tuberculosis (TB) were collected from Dhar district of Madhya Pradesh, India.

Integration of nutritional support (MUKTI initiative) into the NTEP of India.

Routine standard of care in the NTEP of India.

Incremental cost per quality-adjusted life year (QALY) gained.

A mathematical model, combining a Markov model and a compartmental susceptible–infected–recovered model, was used to simulate outcomes for patients with pulmonary TB under NTEP and MUKTI protocols. Primary data collected from 2615 patients with TB, supplemented with estimates from published literature, were used to model progression of disease, treatment outcomes and community transmission dynamics over a 2-year time horizon. Health-related quality of life was assessed using the EuroQol 5-Dimension 5-Level scale. Costs to the health system and out-of-pocket expenditures were included. A multivariable probabilistic sensitivity analysis was undertaken to estimate the effect of joint parameter uncertainty. A scenario analysis explored outcomes without considering community transmission. Results are presented based on health-system and abridged societal perspectives.

Over 2 years, patients in the NTEP plus MUKTI programme had higher life years (1.693 vs 1.622) and QALYs (1.357 vs 1.294) than those in NTEP alone, with increased health system costs (11 538 vs 6807 (US$139 vs US$82)). Incremental cost per life year gained and QALY gained were 67 164 (US$809) and 76 306 (US$919), respectively. At the per capita gross domestic product threshold of 161 500 (US$1946) for India, the MUKTI programme had a 99.9% probability of being cost-effective but exceeded the threshold when excluding community transmission.

The findings highlight the potential benefits of a cost-effective, holistic approach that addresses socio-economic determinants such as nutrition. Reduction in community transmission is the driver of cost-effectiveness of nutritional interventions in patients with TB.

To identify the factors influencing professionals’ implementation of the National Institute for Health and Care Excellence (NICE) guidelines on self-harm.

A rapid review evidence synthesis

Five electronic databases (ASSIA, CINAHL, EMBASE, MEDLINE, PsycINFO) and five indexing databases (Science Citation Index Expanded (SCIE), Social Sciences Citation Index (SSCI), Arts and Humanities Citation Index (AHCI), Emerging Sources Citation Index (ESCI) and Conference Proceedings Citation Index (CPCI)), using the Web of Science platform, were searched in December 2023 and repeated in July 2024.

We included quantitative and qualitative studies that investigated professionals’ knowledge and implementation of NICE guidelines on self-harm, that were in English language and published between 2004 and July 2024.

One reviewer used standardised methods to search, screen, select, quality assess and synthesise the included studies, to accelerate the review. Quality assessment was conducted using the Mixed Methods Appraisal Tool. Data were extracted and synthesised thematically using NICE guidance implementation priorities.

The review included 10 studies. Six were conducted in accident and emergency (A&E) settings, two in general practice, one in a burns and plastic surgery hospital department and one involved cross-sectoral health professionals. Key findings indicate that awareness and implementation of self-harm guidelines is low among health professionals. Systemic barriers include lack of staff training, negative staff attitudes towards people who self-harm and lack of resources.

There is a need to develop and implement regular training on self-harm, incorporating NICE guidance and measures, to integrate knowledge and mobilise practice changes. Further research into the implementation of NICE guidelines in children who self-harm is needed, and in a wider variety of health and social care settings. The absence of studies from the social care sector into professionals’ awareness and implementation of NICE guidelines on self-harm is a key limitation.

Colorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer-related death globally. Growing evidence links gut microbiota dysbiosis to CRC, with several reviews reporting consistent microbial alterations in CRC patients that may serve as non-invasive biomarkers. However, findings vary across studies, and consensus on key microbial taxa is lacking. This umbrella review aims to clarify: (1) the association between gut microbiome composition and CRC development/progression, (2) specific microbial taxa linked to CRC risk, (3) the role of microbiome diversity in CRC outcomes and (4) potential microbial biomarkers for diagnosis, prognosis and treatment response.

This umbrella review will follow the Joanna Briggs Institute (JBI) Umbrella Review Guidelines and adhere to the Preferred Reporting Items for Overviews of Reviews. A comprehensive search will be conducted across MEDLINE (PubMed), Embase, CINAHL and key systematic review databases, including the Cochrane Database, JBI Evidence Synthesis and Database of Abstracts of Reviews of Effects, without language restrictions. The search strategy will use a combination of Medical Subject Headings terms and free-text keywords with Boolean operators. The review questions were developed using the Population, Concept and Context framework. Only high-quality (as determined by the JBI Critical Appraisal Checklist for Systematic Reviews and Research Syntheses), peer-reviewed quantitative systematic reviews with or without meta-analyses will be included. Overall effect estimates extracted from systematic reviews, with the number of studies that inform the outcome, will be presented.

No ethical approval is required since the work is carried out on published documents. Findings of this review will be disseminated among relevant stakeholders through multiple scientific avenues, including presentations at both national and international forums and manuscript publication in an open-access journal.

This study aimed to determine the prevalence of non-communicable diseases (NCDs) among pregnant women in Sri Lanka and examine the association between NCDs and maternal and fetal outcomes.

A hospital-based, descriptive cross-sectional study.

The study was conducted in three tertiary care hospitals in the Western Province and one intermediate obstetrics care facility in the Southern Province of Sri Lanka, encompassing diverse, multiethnic populations, over 3 months.

Data from 1350 pregnant women were collected from discharged bed head tickets of the postnatal obstetric wards using a standardised checklist.

The primary outcomes were the prevalence of NCDs. Secondary outcomes included associations between maternal NCDs and adverse fetal outcomes such as preterm births and neonatal complications.

Among the participants, 68.5% (n=926) had one or more NCDs, with anaemia (37.9%), obesity (18.1%), gestational diabetes mellitus (14.9%) and hypertensive disorders (13.6%) being the most prevalent. Women with NCDs were at significantly higher odds of adverse fetal outcomes, including preterm birth (OR=2.3, 95% CI: 1.5 to 3.4), neonatal sepsis (OR=2.5, 95% CI: 1.5 to 4.04) and hypoglycaemia (OR=3.5, 95% CI: 1.2 to 10.0). Maternal complications, including postpartum haemorrhage (3.3%) and placental abruption (0.7%), were also more frequent in this group.

NCDs are highly prevalent among pregnant women in Sri Lanka and are significantly associated with adverse maternal and fetal outcomes. Enhanced screening and management strategies during antenatal care are essential to mitigate risks and improve health outcomes, aligning with global efforts to reduce maternal and neonatal morbidity and mortality.

To identify the patterns of tuberculosis (TB) notification rates and examine their relationship with social and economic determinants in Nepal between 2020 and 2023.

Cross-sectional study.

Nepal.

All TB cases across all ages.

Prevalence of TB cases.

This cross-sectional spatial analysis used the data set of the National Tuberculosis Control Centre, Nepal, covering the Fiscal Year (FY) 2020–2021 to 2022–2023. Moran’s I and Local Indicators of Spatial Association were employed to detect the spatial autocorrelation between the prevalence of TB and associated social and demographic factors.

The overall prevalence rate for TB in FY 2020–2021 was 98.08 per 100 000 population. This increased to 129.82 per 100 000 population in FY 2021–2022, followed by a slight decrease to 128.39 per 100 000 population in FY 2022–2023. The highest TB prevalence was observed in Kathmandu, with 146 cases per 100 000 population in 2020–2021, and in Dang district, the rate decreased from 215–191 per 100 000 population. We investigated the spatial patterns of TB prevalence and highlighted the geographic areas in each district in Nepal from 2021 to 2023 with Moran’s I of 0.558, 0.614 and 0.596, respectively. The consistent identification of High-High clusters in specific districts like Banke, Kapilbastu and Parsa across all 3 years periods highlighted persistent high-risk areas for TB transmission in Nepal.

This study emphasised the strong spatial associations and the complex, diverse aspects of TB transmission shaped by demographic and socioeconomic factors. Our results highlighted the need for tailored public health approaches that account for specific social determinants to address TB effectively.

To analyse patient profiles, transportation patterns and time delays in ischaemic time and door-to-balloon (DTB) time and evaluate the effect of these delays on in-hospital mortality among patients undergoing primary percutaneous coronary intervention (P-PCI) for ST-segment elevation myocardial infarction (STEMI) at a tertiary care hospital in Colombo.

Retrospective observational study.

Tertiary care hospital specialising in STEMI treatment, located in Sri Lanka.

The study included adults aged 16–87 years admitted for P-PCI between January 2018 and September 2023, presenting with STEMI and undergoing emergency P-PCI. Patients with incomplete records or unrealistic values on ischaemic time or DTB time were excluded.

Outcome measures include ischaemic time, DTB time and in-hospital mortality. The associations of demographic factors, transfer methods and DTB time with survival rates were analysed.

A total of 1758 patients underwent P-PCI (mean age, 53.0±11.64), with 85.2% being male. The male risk group was 46–60 years (OR, 1.22), whereas the female risk group was predominantly older than 60 years (OR, 1.87). The median ischaemic time was 4 hours and 36 min, and the median DTB time was 110 min. The in-hospital mortality rate was 3.8% (63/1,664). Prolonged DTB times exceeding 120 min were significantly associated with increased mortality (p=0.046), although alternative thresholds (45, 60 or 90 min) were not significant (p>0.05). Binary logistic regression with multiple variables identified female sex (OR, 2.52; 95% CI, 1.168 to 5.435, p=0.018), increasing age (OR 1.05; 95% CI, 1.016 to 1.085, p=0.004) and DTB times (OR, 1.001; 95% CI, 1.000 to 1.002, p=0.027) as independent predictors of mortality.

Despite improvements in DTB times, this study indicates that prolonged delays exceeding 120 min remain associated with increased mortality. Older age and female sex were identified as independent predictors of higher mortality. These findings underscore the need for efficient patient transfer methods and prompt decision-making at the primary healthcare level to minimise delays and disparities in P-PCI outcomes.

Psychotic disorders are more prevalent among minority ethnic groups in the UK. However, there is no research on how the British Sikh community understands and seeks help for psychosis. The way in which a community understands the nature, causes and treatment of psychosis can impact their duration of untreated psychosis, treatment pathways, experience and engagement with mental health services, and outcomes.

To explore the lay understandings of psychosis and associated help-seeking within the Sikh community in England, and how family, religion and culture influence these perspectives

An exploratory qualitative design, consisting of online semistructured interviews across the UK.

30 participants, 11 men and 19 women, ages ranged from 19 to 69, who identified as Sikh.

Thematic analysis revealed several common themes, including a lack of awareness and knowledge of psychosis, variety of causal beliefs held about psychosis, professional help-seeking being encouraged, religious practices regarded as helpful coping mechanisms, supernatural beliefs influencing alternative help-seeking, strong negative perceptions towards psychosis and general mental illness, the significant role of family and community, and conflicting religious and cultural beliefs.

Participants showed limited understanding of psychosis and mental illnesses, accompanied by widespread negative perceptions, potentially delaying help-seeking. Increasing awareness may prompt earlier help-seeking, enhancing outcomes and diminishing stigma.

Perinatal care continuity across the full continuum is essential for optimising maternal and infant health; however, a stark gap occurs post partum, with less than one half of Indian mothers receiving postpartum care due to significant logistical and sociocultural barriers, particularly for periurban and rural residents. To overcome these barriers and reduce women’s postpartum isolation, our international team of maternal and infant health clinicians and researchers developed and pilot-tested a culturally-tailored mobile interactive education and support group intervention, Kushal Maa (‘informed-mother’), confirming feasibility and acceptability and preliminary effectiveness. The current study seeks to estimate the effectiveness of the Kushal Maa intervention compared with standard care on maternal and neonatal health-related behaviours and health, characterise the mechanisms of intervention impact and evaluate the cost-effectiveness of the Kushal Maa intervention in improving postpartum maternal and neonatal health compared with the standard of care.

We will conduct a prospective, parallel block-randomised controlled trial with a 1:1 allocation ratio among 2100 pregnant women across three geographically diverse Indian states. Inclusion criteria for women: aged 18+years of age at enrolment, in the last trimester of pregnancy (30–33 weeks of gestation), with any parity, carrying single or multiple gestation (1-2), with knowledge of site-specific local language and had access to a mobile phone. Participants will be block-randomised in groups of 15. Intervention participants will receive 28 tailored education and support sessions weekly via audio/video conference facilitated by trained moderators (four prenatal and 24 weekly postpartum sessions through 6 months) and will be engaged in WhatsApp groups for health education videos and peer discussion via text chat. Control participants receive the standard of care. Data will be collected at four points: 30–33 weeks of pregnancy (enrolment), 6 weeks, 3 months and 6 months postpartum (endline). Investigators, outcome assessors and data analysts will be blinded to group allocation. Primary outcomes will be measured at 6 weeks, 3 months and 6 months post partum and include: postpartum depression (using Edinburgh Postnatal Depression Scale), exclusive breastfeeding and met need for postpartum family planning. Secondary outcomes include other maternal and child health knowledge, outcomes and maternal and newborn healthcare use indicators. We will use intention-to-treat analysis. Mixed-effects models will account for clustering due to the group-oriented delivery of the intervention and repeated measures.

The objective of the study was to understand the smoking behaviour of adults and how societal perceptions influence the smoking behaviour of university students.

Qualitative study.

National Institute of Medical Sciences university, India.

20 face-to-face interviews were carried out among university students who were in the age group of 19–30 years using a combination of purposive sampling, followed by snowball sampling methods.

Qualitative responses revealed that stress, cravings for cigarettes and mealtimes were key triggers for smoking behaviour. Many participants felt guilty about their smoking and often became irritated by advice from non-smoking friends. All participants had experienced negative health effects, including physical and sensory issues, as well as other adverse experiences. Students expressed a dislike for judgemental attitudes from society. They respected elders and found it difficult to smoke in front of them. Rather than being blamed for their smoking, they preferred supportive assistance to help them quit.

The study highlights the importance of understanding college students’ smoking behaviour, as it greatly influences their smoking habits. Cessation efforts should target this group and emphasise the negative experiences associated with smoking. Additionally, students recommend creating a non-judgemental and supportive environment to aid in quitting, rather than a judgemental and blaming society.

Caesarean birth (CB) under neuraxial anaesthesia (NA) is the most performed inpatient operation in the UK. The incidence of intraoperative pain during caesarean delivery performed under neuraxial anaesthesia is unclear, with limited data that used patient-reported measures to investigate intraoperative pain. The short- and medium-term impacts on patients of this adverse event are unknown.

We will undertake a multicentre, prospective observational cohort study to evaluate the incidence and impact of pain experienced by patients during CB performed under neuraxial anaesthesia. Routine audit data will be collected for all patients undergoing caesarean delivery for any indication during a 1 week window at participating hospitals within the UK and Queensland, Australia. The dataset will include patient, anaesthetic, obstetric and neonatal risk factors for intraoperative pain. Local investigators will then seek informed consent from patients either before or within 24 hours of delivery to record patient experience and patient-reported outcomes at 24 hours and 6 weeks postdelivery. Local investigators at participating hospitals will also complete a survey evaluating compliance with evidence-based structural standards at their sites. The patient characteristics, structures, processes and outcomes will be described. Inferential techniques will be used to evaluate the relationship between risk factors and postoperative outcomes.

This study received ethical approval from the Leicester Health Research Authority and Care Research Wales, REC reference 24/EM/0084) on 24 May 24. The study received ethical approval from the Human Research Ethics Committee of Metro North Health in Australia on 25 March 2024 (REC Ref HREC/2024/MNHA/103767). The results of the study will be reported in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology statement. The results will be disseminated via conference presentations, peer-reviewed academic journals and reports prepared for patients, the public and policy makers.

Knee osteoarthritis (OA) is a serious public health problem since it is linked to loss of muscular function and independence, especially in older adults. In this study, the researchers have proposed a randomised controlled trial with a three-arm study strategy to explore the effectiveness of an oral nutritional supplementation containing hydroxymethylbutyrate and undenatured type-II collagen combined with exercise training (ET) on the OA-related symptoms and biomarkers among adults with knee OA.

Adults with knee OA aged between 50 years and 75 years will be invited to participate in the study and thereafter will be randomly assigned to either one of three groups: oral nutrition supplementation+ET, ET or usual care. The primary outcomes include changes in OA-related symptoms and biomarkers. The secondary outcomes include changes in body composition, blood profiles, physical fitness, quality of life, dietary intake, disability, psychology status and morphological changes of the knee.

Ethics approval was granted by the Medical Research Ethics Committee of the National University of Malaysia (reference number JEP-2024–264). Findings of this study will be disseminated via peer-reviewed presentations at scientific conferences as well as open access publications.

To compare cardiovascular mortality (ischaemic heart disease (IHD), hypertensive disease (HTN) and cerebrovascular disease (CeVD)) of 40–69-year-old Sri Lankans from 1980 to 2010 by age, birth cohort and sex.

A comparative retrospective study.

Sri Lanka.

40–69-year-old Sri Lankans from 1980 to 2010.

Cardiovascular deaths due to IHD, HTN and CeVD.

Mortality due to IHD increased with age but decreased with birth cohorts with time (range 3.7–390 per 100 000 population); there was a spike in the IHD mortality rates in both age groups and birth cohorts in 2000. Deaths due to HTN markedly increased after 55 years; however, mortality decreased in the younger cohorts (range 2.8–204.81 per 100 000 population). CeVD mortality linearly increased with age (range 3.3–153.3 per 100 000 population); birth cohorts of 1926–1930 and 1931–1935 had a spike in mortality among the 60–64 and 65–69 age groups, respectively. Changes were seen among both males and females; mortality rates were higher in males than in females.

All cardiovascular mortality rates increased with age and are higher in males than in females. Age-specific cardiovascular mortality rates were lower in the younger birth cohorts as compared with the older birth cohorts. The increase in cardiovascular deaths in Sri Lanka is due to the ageing population.

Childhood tuberculous meningitis (TBM) is a devastating disease. The long-standing WHO recommendation for treatment is 2 months of intensive phase with isoniazid (H), rifampicin (R), pyrazinamide (Z) and ethambutol (E), followed by 10 months of isoniazid and rifampicin. In 2022, WHO released a conditional recommendation that 6 months of intensified antituberculosis therapy (ATT) could be used as an alternative for drug-susceptible TBM. However, this has never been evaluated in a randomised clinical trial. Trials evaluating ATT shortening regimens using high-dose rifampicin and drugs with better central nervous system penetration alongside adjuvant anti-inflammatory therapy are needed to improve outcomes.

The Shortened Intensive Therapy for Children with Tuberculous Meningitis (SURE) trial is a phase 3, randomised, partially blinded, factorial trial being conducted in Asia (India and Vietnam) and Africa (Uganda, Zambia and Zimbabwe). It is coordinated by the Medical Research Council Clinical Trial Unit at University College London (MRCCTU at UCL). 400 children (aged 29 days to

Local ethics committees at all participating study sites and respective regulators approved the SURE protocol. Ethics approval was also obtained from UCL, UK (14935/001). Informed consent from parents/carers and assent from age-appropriate children are required for all participants. Results will be published in international peer-reviewed journals, and appropriate media will be used to summarise results for patients and their families and policymakers.
