Purpose: Climate change is now the greatest threat to human survival. The healthcare system contributes significantly to global pollution and greenhouse gas emissions. Individual practitioners play an important role in helping to reduce these impacts in day-to-day practice. Deimplementation of unnecessary processes and products, such as exam table paper, in medical offices is one simple approach to incorporating principles of planetary health into practice. All quality improvement (QI) projects must start to consider environmental impacts to fully evaluate change ideas., Methods: We designed a single Plan-Do-Study-Act cycle using the Institute for Health Improvement Model for Improvement. We removed the exam table paper from our primary care office and measured changes in staff time, laundry, financial costs, paper use and carbon dioxide (CO 2 ) emissions., Results: Eliminating exam table paper in our clinic resulted in modest annual cost savings of $C718 and improved staff efficiency and motivation to introduce other green office practices. In our clinic alone, this change will save 8.2 km of exam table paper, 10 trees and 148 kg of CO2e (equivalent to driving 1233 km) every year. There were no negative consequences or feedback., Conclusions: This simple QI project demonstrates the feasibility of implementing a small change in a primary care clinic that can improve environmental sustainability with multiple co-benefits. If all family physicians in Canada eliminated exam table paper in their offices, it would result in savings of approximately 95 940 km of paper, 121 680 trees, $C8 400 600 and 3054 T CO 2 emissions, equivalent to driving around the world 360 times., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Early-career surgeons must be exposed to a sufficient number of surgical cases of varying complexity in a mentored environment to allow them to solidify, sustain and build on the skills gained in training. Decreased operative volumes at military treatment facilities and assignments that do not include strong mentoring environments can place military surgeons at a disadvantage relative to their civilian counterparts during this critical time following training. The challenge of lower operative volumes in the current interwar lull has been exacerbated by the decline in beneficiary care conducted within the Military Healthcare System. These challenges must be addressed by ensuring early-career surgeons maintain exposure to a large volume of complex surgical procedures and deliberate mentoring from senior surgeons. The purpose of this position statement is to provide actionable methods to support early-career military surgeons to effectively transition from training to independent practice.

Introduction Research has provided novel insights into how light stimulates circadian rhythms through specialised retinal ganglion cells to the suprachiasmatic nucleus. In addition, there has been a revolution in light-emitting diode (LED) technology, leading to tunable LED light sources and lighting systems, enabling 24-hour dynamic light scenarios with bright blue-enriched short wavelength light during the day and dim evening light, stimulating the circadian system. These dynamic LED lighting systems are now being implemented at hospitals without adequate understanding of how it may affect the health and well-being of patients and staff.Methods and analysis An optimised dynamic LED lighting scenario is investigated at a newly built psychiatric hospital in Copenhagen. In the 12 months baseline period, a standard lighting scenario with dynamic colour temperature and fixed light intensity is investigated. In the following 12-month intervention period, a new DEL scenario is investigated, having dynamic colour temperature as well as dynamic light intensity with a higher daytime and lower evening-time melanopic daylight equivalent illuminance. This setting is furthermore adjusted for geographical orientation to compensate for differences in sunlight access in wintertime. The study uses a quasiexperimental design comparing patients admitted in the two study periods. Prior to each of the study periods, daylight and the contribution from the LED-lighting scenarios was measured. Patient sociodemographic and mental health data will be retrieved retrospectively from electronic medical records and by questionnaires administered in the two periods, evaluating lighting, noise, sleep quality and quality of life. Primary outcome is the proportion of patients receiving pro re nata medications. Secondary outcomes are the length of stay, sleep onset latency, sleep quality and quality of life.Ethics and dissemination No ethical issues are expected. The results will be disseminated through peer-reviewed international journal, lectures, posters and interviews.Trial registration number NCT05868291.

Introduction Paediatric concussion is a common injury. Approximately 30% of youth with concussion will experience persisting postconcussion symptoms (PPCS) extending at least 1 month following injury. Recently, studies have shown the benefit of early, active, targeted therapeutic strategies. However, these are primarily prescribed from the specialty setting. Early access to concussion specialty care has been shown to improve recovery times for those at risk for persisting symptoms, but there are disparities in which youth are able to access such care. Mobile health (mHealth) technology has the potential to improve access to concussion specialists. This trial will evaluate the feasibility of a mHealth remote patient monitoring (RPM)-based care handoff model to facilitate access to specialty care, and the effectiveness of the handoff model in reducing the incidence of PPCS.Methods and analysis This study is a non-randomised type I, hybrid implementation-effectiveness trial. Youth with concussion ages 13–18 will be enrolled from the emergency department of a large paediatric healthcare network. Patients deemed a moderate-to-high risk for PPCS using the predicting and preventing postconcussive problems in paediatrics (5P) stratification tool will be registered for a web-based chat platform that uses RPM to collect information on symptoms and activity. Those patients with escalating or plateauing symptoms will be contacted for a specialty visit using data collected from RPM to guide management. The primary effectiveness outcome will be the incidence of PPCS, defined as at least three concussion-related symptoms above baseline at 28 days following injury. Secondary effectiveness outcomes will include the number of days until return to preinjury symptom score, clearance for full activity and return to school without accommodations. The primary implementation outcome will be fidelity, defined as the per cent of patients meeting specialty care referral criteria who are ultimately seen in concussion specialty care. Secondary implementation outcomes will include patient-defined and clinician-defined appropriateness and acceptability.Ethics and dissemination This study was approved by the Institutional Review Board of the Children’s Hospital of Philadelphia (IRB 22-019755). Study findings will be published in peer-reviewed journals and disseminated at national and international meetings.Trial registration number NCT05741411.

Introduction While research into adolescent mental health has developed a considerable understanding of environmental and psychosocial risk factors, equivalent biological evidence is lacking and is not representative of economic, social and ethnic diversity in the adolescent population. It is important to understand the possible barriers and facilitators to conduct this research. This will then allow us to improve our understanding of how biology interacts with environmental and psychosocial risk factors during adolescence. The objective of this scoping review is to identify and understand the needs, barriers and facilitators related to the collection of biological data in adolescent mental health research.Methods and analysis Reviewers will conduct a systematic search of PubMed, Medline, Scopus, Cochrane, ERIC, EMBASE, ProQuest, EBSCO Global Health electronic databases, relevant publications and reference lists to identify studies published in the English language at any time. This scoping review will identify published studies exploring mental health/psychopathology outcomes, with biological measures, in participants between the ages of 11 and 18 and examine the reported methodology used for data collection. Data will be summarised in tabular form with narrative synthesis and will use the methodology of Levac et al, supplemented by subsequent recommendations from the Joanna Briggs Institute Scoping Review Methodology.Ethics and dissemination Ethical approval is not required for this scoping review. The scoping review will be conducted with input from patient and public involvement, specifically including young people involved in our study (‘Co-producing a framework of guiding principles for Engaging representative and diverse cohorts of young peopLE in Biological ReseArch in menTal hEalth’—www.celebrateproject.co.uk) Youth Expert Working Group. Dissemination will include publication in peer-reviewed journals, academic presentations and on the project website.

Objectives To map the current use of paper-based and/or screen-based media for health education aimed at older people.Design A scoping review was reported following the Preferred Reporting Items of Systematic Reviews and Meta-analyses for Scoping Reviews checklist.Data sources The search was carried out in seven databases (Scopus, Web of Science, Embase, Medline, CINAHL, ACM Guide to Computing Literature, PsycINFO), with studies available from 2012 to the date of the search in 2022, in English, Portuguese, Italian or Spanish. In addition, Google Scholar was searched to check the grey literature. The terms used in the search strategy were older adults, health education, paper and screen-based media, preferences, intervention and other related terms.Eligibility criteria Studies included were those that carried out health education interventions for older individuals using paper and/or screen-based media and that described barriers and/or facilitators to using these media.Data extraction and synthesis The selection of studies was carried out by two reviewers. A data extraction form was developed with the aim of extracting and recording the main information from the studies. Data were analysed descriptively using Bardin’s content analysis.Results The review included 21 studies that carried out health education interventions with different purposes, the main ones being promotion of physical activity, hypertension prevention and psychological health. All 21 interventions involved screen-based media on computers, tablets, smartphones and laptops, while only 4 involved paper-based media such as booklets, brochures, diaries, flyers and drawings. This appears to reflect a transition from paper to screen-based media for health education for the older population, in research if not in practice. However, analysis of facilitators and barriers to using both media revealed 10 design factors that could improve or reduce their use, and complementarity in their application to each media type. For example, screen-based media could have multimedia content, additional functionality and interactivity through good interaction design, but have low accessibility and require additional learning due to complex interface design. Conversely, paper-based media had static content and low functionality but high accessibility and availability and a low learning cost.Conclusions We recommend having improved screen-based media design, continued use of paper-based media and the possible combination of both media through the new augmented paper technology.Registration number Open Science Framework (DOI: 10.17605/OSF.IO/GKEAH).

Introduction Technological advancement in low-resource settings is opening the gateway to implementation of electronic data collection methods that improve data quality. We examined the concerns to use electronic data collection tool in Zanzibar, codeveloped a tool that addressed the concerns and evaluated the process and limitations of incorporating an electronic data collection tool aside from paper-based during a community-based study in Zanzibar.Methods The science of improvement Plan-Do-Study-Act model guided this mixed-method participatory action research (PAR). From November 2022 to October 2023, 14 data collection team members participated in (1) a consultative workshop with a fishbone analysis to understand their hesitance to use electronic data collection tools for fieldwork (Plan); (2) developing implementation and evaluation plan for the paper-based method (Do); (3) assessing the proportion of errors and challenges faced using paper-based method (Study); and (4) codeveloping, implementing and assessing an electronic data collection tool (Act).Results Stakeholders were hesitant to use electronic data collection tools because of fear of lost data due to poor internet, insufficient competency with technology due to lack of training, unfamiliarity with technology in general and fear of lost wages. The study revealed that using a paper-based data collection tool during baseline was time-consuming, with 12.8% of responses being errors (2611 errors out of 20 398 responses). However, once implemented, the electronic data collection application was fast and simple, with minimal errors (0.02%). Overall, there is a need to improve devices’ storage capacity devices and provide more training.Conclusion Using the PAR approach, we understood the concerns with electronic data collection tools, allowed the team to experience the challenges faced with the paper-based collection method, codeveloped an appropriate solution and changed their attitude towards using technology that could increase accuracy and efficiency of their fieldwork.

Objective Since the emergence of COVID-19, university education has drastically transformed into digital-based learning (DBL). Online education has been well recognised as a promising mode of teaching; however, only a limited number of studies have reported the students’ preferred format for academic learning.Design Cross-sectional.Setting The study was conducted in a university setting in Japan. A Google Forms online questionnaire was distributed to the participants between April and May 2022.Participants A total of 939 undergraduate medical, nursing and pharmaceutical students in the pre-clinical grade were recruited, and 344 were included in the final analysis.Primary and secondary outcome The questionnaire assessed students’ format preferences between paper-based learning (PBL) and DBL as it pertained to academic performance and eyestrain. In terms of academic performance, comprehension, memory retention and absorption (concentration) were assessed. We also explored the association between students’ daily time spent using DBL and their digital preference by the Cochran-Armitage trend test and logistic regression analysis.Results A total of 344 (191 medical, 73 nursing and 80 pharmaceutical) university students completed the questionnaire (response rate 36.6%). An even distribution was observed in the preferred learning format for comprehension: PBL (32.0%), both formats equivalent (32.8%) and DBL (35.2%; digital preference). Only few students preferred DBL for memory retention (6.1%), absorption (6.7%) and eyestrain (1.2%). Although a positive association was observed between daily time spent using DBL and digital preference for comprehension, there was no association for memory retention, absorption and eyestrain.Conclusion Among university students, DBL was just as preferred as PBL for comprehension; however, only a few students reported that DBL was better in terms of memory retention, absorption and eyestrain. A learning environment where students can study using PBL should be continued.

Introduction: As a topic of inquiry in its own right, data management for interdisciplinary research projects is in its infancy. Key issues include the inability of researchers to effectively query diverse data outputs and to identify potentially important synergies between discipline-specific data. Equally problematic, few semantic ontologies exist to better support data organisation and discovery. Finally, while interdisciplinary research is widely regarded as beneficial to unpacking complex problems, non-researchers such as policy-makers and planners often struggle to use and interrogate the related datasets. To address these issues, the following article details the design and development of the UKRI GCRF Action Against Stunting Hub (AASH)'s All-Hub Data Repository (AHDR)., Methods and Analysis: The AHDR is a single application, single authentication web-based platform comprising a data warehouse to store data from across the AASH's three study countries and to support data querying. Four novel components of the AHDR are described in the following article: (1) a unique data discovery tool; (2) a metadata catalogue that provides researchers with an interface to explore the AASH's data outputs and engage with a new semantic ontology related to child stunting; (3) an interdisciplinary aid to support a directed approach to identifying synergies and interactions between AASH data and (4) a decision support tool that will support non-researchers in engaging with the wider evidence-based outputs of the AASH., Ethics and Dissemination: Ethical approval for this study was granted by institutional ethics committees in the UK, India, Indonesia and Senegal. Results will be disseminated via publications in peer-reviewed journals; presentations at international conferences and community-level public engagement events; key stakeholder meetings; and in public repositories with appropriate Creative Commons licences allowing for the widest possible use., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objectives Current mental health practices for people living in residential aged care (RAC) facilities are poor. In Australia, there are no mechanisms to monitor and promote mental health for people living in RAC, including those who experience changed behaviours and psychological symptoms. The aim of this study is to improve current practices and mental health outcomes for people living in RAC facilities by codesigning a Mental Health benchmarking Industry Tool for residential aged Care (MHICare Tool).Methods A two-stage sequential and mixed methods codesign methodology will be used. Stage 1 will include qualitative interviews and focus groups to engage with residents, family/care partners and RAC staff to ascertain mental healthcare practices and outcomes of greatest significance to them. Adapted concept mapping methods will be used to rank identified issues of concern in order of importance and changeability, and to generate draft quality indicators. Stage 2 will comprise a Delphi procedure to gain the wider consensus of expert panel views (aged care industry, academic, clinical) on the performance indicators to be included, resulting in the codesigned MHICare Tool.Ethics and dissemination This study has been reviewed and approved by the University of Queensland Human Research Ethics Committee (HREC/2019002096). This project will be carried out according to the National Statement on Ethical Conduct in Human Research (2007). The study’s findings will be published in peer-reviewed journals and disseminated at national and international conferences and through social media.Conclusion This protocol reports structured methods to codesign and develop a mental health performance indicator tool for use in Australian RAC.

Introduction Air pollution is a global issue that poses a significant threat to public health. Children, due to their developing physiology, are particularly susceptible to the inhalation of environmental pollutants. Exposure can trigger immune modulation and organ damage, increasing susceptibility to respiratory diseases. Therefore, we aim to examine the association between heavy metal and particulate matter exposure with tuberculosis in children.Methods and analysis As a case–control study, we will include children diagnosed with pulmonary tuberculosis (n=60) and matched healthy controls (n=80) recruited from the same communities in Dhaka, Bangladesh. Exposure data for both cases and controls will be collected by a trained field team conducting home visits. They will administer an exposure questionnaire, measure child anthropometry, collect blood and household dust samples and instal 48-hour air quality monitors. The blood samples will be analysed by inductively coupled plasma mass spectrometry for serum heavy metal concentrations (lead, cadmium, arsenic, mercury and chromium), as a representative marker of exposure, and the presence of inflammatory biomarkers. Descriptive and inferential statistics, including independent samples t-tests, analysis of variance and conditional regression analysis, will be used to quantify heavy metal and particulate matter exposure status in tuberculosis cases compared with healthy controls, while accounting for potential confounders. Dust samples and air quality results will be analysed to understand household sources of heavy metal and particulate matter exposure. To test the study hypothesis, there is a positive association between exposure and tuberculosis diseases, we will also measure the accumulated effect of simultaneous exposures using Bayesian statistical modelling.Ethics and dissemination This study has been approved by International Centre for Diarrhoeal Disease Research, Bangladesh’s Institutional Review Board (PR-22030). The study findings will be disseminated at conferences and published in peer-reviewed journals.

Introduction: Several factors have been implicated in child stunting, but the precise determinants, mechanisms of action and causal pathways remain poorly understood. The objective of this study is to explore causal relationships between the various determinants of child stunting., Methods and Analysis: The study will use data compiled from national health surveys in India, Indonesia and Senegal, and reviews of published evidence on determinants of child stunting. The data will be analysed using a causal Bayesian network (BN)-an approach suitable for modelling interdependent networks of causal relationships. The model's structure will be defined in a directed acyclic graph and illustrate causal relationship between the variables (determinants) and outcome (child stunting). Conditional probability distributions will be generated to show the strength of direct causality between variables and outcome. BN will provide evidence of the causal role of the various determinants of child stunning, identify evidence gaps and support in-depth interrogation of the evidence base. Furthermore, the method will support integration of expert opinion/assumptions, allowing for inclusion of the many factors implicated in child stunting. The development of the BN model and its outputs will represent an ideal opportunity for transdisciplinary research on the determinants of stunting., Ethics and Dissemination: Not applicable/no human participants included., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: Environmental hygiene and food safety are important determinants of child stunting. This research aims to explore the relationship between child stunting and household hygiene practices and behaviours, including the availability of water, sanitation and hygiene (WASH) facilities; the use of safe food and good quality drinking water (especially when used for complementary feeding); hygienic practices in food transport, storage and preparation and the control of cross-contamination from animals, their produce and waste., Methods and Analysis: This study is part of a wider observational study which aims to investigate the interdisciplinary factors contributing to child stunting using a 'whole child' paradigm. The observational study recruits women during pregnancy in Hyderabad, India, Lombok, Indonesia and Kaffrine, Senegal, and dyads (ie, 500 mother-infant pairs per country) are followed longitudinally up to 24 months after birth. Within the interdisciplinary niche, the study here has developed tools to investigate the potential exposure pathways to environmental pathogen contamination of foods and water. Holistic WASH and food safety data collection tools have been developed to explore exposure pathways at the household level, including: (1) survey questionnaires; (2) spot-checks; (3) biological sampling of drinking water, food and domestic surfaces and (4) direct observation. An integrated analytical approach will be used to triangulate the evidence in order to examine the relationships between child stunting, WASH and food safety behaviours., Ethics and Dissemination: Ethical approval of the study was granted by the ethics committee of the LSHTM, RVC, ILRI, ICMR, IIPHG, SEAMEO-RECFON, University of Cheikh Anta Diop. Findings of the study will be disseminated through publication in peer-reviewed journals, relevant international conferences, public engagement events, and policy-maker and stakeholder events., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: Childhood stunting is associated with poorer child health, growth and development including diminished cognitive abilities. Mapping out the links between child stunting and Early Childhood Education and Development is critical to increasing understanding of the causes and effects of childhood stunting, and for programme and policy development. The aim of this study is to investigate and compare the development and educational environments across India, Indonesia and Senegal, and to identify the multifactorial drivers and impacts of childhood stunting to inform a new typology., Methods and Analysis: This current study is part of an interdisciplinary observational research study, where women are recruited during pregnancy and mother-infant pairs followed prospectively, up to 24 months after birth. Eight measures will be used to profile children's early development and learning environments in two sample cohorts: (A) children aged 12 and 24 months born to the women recruited during pregnancy (ie, 500 pregnant mothers per country) and (B) a preschool case-control cohort of siblings from the main cohort aged between 3:6 and 5:6 years of age where anthropomorphic measures will be collected to assess degrees of stunting. Profiling of the development and learning environments in the countries will include both parent/caregiver self-reported and local staff (enumerators) direct assessments of children and settings., Ethics and Dissemination: This study was approved by the institutional ethics committees of all partner institutions. In India, Indian Council of Medical Research-National Institute of Nutrition, Hyderabad; In Indonesia, Ethics Committee of the Faculty of Medicine, University of Indonesia; and in Senegal, National Ethics Committee for Scientific Research in Senegal.The findings of the study will be disseminated in national and international meetings, seminars, conferences and peer-reviewed journals., Competing Interests: Competing interests: None., (© Author(s) (or their employer(s)) 2024.

Introduction: The COVID-19 pandemic has offset some of the gains achieved in global health, particularly in relation to maternal, child health and nutrition. As pregnancy is a period of plasticity where insults acting on maternal environment have far-reaching consequences, the pandemic has had a significant impact on prenatal outcomes, intrauterine and postnatal development of infants. This research will investigate both the direct and indirect impacts of the COVID-19 pandemic during pregnancy on prenatal outcomes, growth and development in early childhood., Methods and Analysis: Community and hospital data in Hyderabad and Gujarat, India will be used to recruit women who were pregnant during the COVID-19 pandemic and contracted SARS-CoV-2 infection. In comparison with women who were pregnant around the same time and did not contract the virus, the study will investigate the impact of the pandemic on access to healthcare, diet, nutrition, mental health and prenatal outcomes in 712 women (356 per study arm). Children born to the women will be followed prospectively for an 18-month period to investigate the impact of the pandemic on nutrition, health, growth and neurocognition in early childhood., Ethics and Dissemination: Ethics approval was granted from the institutional ethics committees of the Indian Institute of Public Health Gandhinagar (SHSRC/2021/2185), Indian Council of Medical Research-National Institute of Nutrition (EC/NEW/INST/2021/1206), and London School of Hygiene and Tropical Medicine (72848). The findings of the study will be disseminated to policy and research communities through engagements, scientific conferences, seminars, and open-access, peer-reviewed publication., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Inadequate access to affordable, safe, desirable and convenient nutrient-dense food is one of the underlying causes of child stunting. While targeted nutrition-sensitive interventions (eg, backyard 'nutri-gardens') may increase dietary diversity within farming households, such interventions have limited scalability across the wider food system where markets remain underdeveloped. This research aims to develop and assess market-based interventions for key nutrient-dense foods to help improve the diets of women and children in the first 1000 days of life., Methods: Data collection uses four parallel approaches in each of the three study countries (India, Indonesia and Senegal). (1) A novel food environment tool will be developed to characterise the accessibility and affordability of nutrient-dense foods in the study countries. The tool will be validated through pretesting using cognitive interviewing and piloting in purposively sampled households, 10 (cognitive interviewing) and 30 (piloting) households in each country; (2) stakeholder interviews (eg, with producers, intermediaries and retailers) will be conducted to map out nutrition-sensitive entry points of key value chains (eg, animal-sourced foods), before hotspots of potential food safety hazards will be identified from food samples collected along the chains; (3) the Optifood and Agrifood tools will be used to identify foods that can address food system nutrient gaps and engage key stakeholders to prioritise market interventions to improve nutrition outcomes. Optifood and Agrifood parameters will be informed by publicly available data, plus interviews and focus groups with value chain stakeholders; (4) informed by the previous three approaches and a campaign of participatory 'group model building', a novel system dynamics model will evaluate the impact of alternative market-based solutions on the availability and affordability of nutrient-dense foods over time., Ethics and Dissemination: The study has received ethical approval in the United Kingdom, Senegal, Indonesia and India. Dissemination comprises peer-reviewed journals, international disciplinary conferences and multistakeholder dissemination workshops., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: In 2020, an estimated 150 million children under the age of 5 years were stunted. Stunting results from early-life adversity and it is associated with significant physical and cognitive deficit, lifelong socioeconomic disadvantage and reduced life expectancy. There is a need to understand the causes of stunting and its effects in order to develop strategies to avoid it and to mitigate the consequences once stunting has occurred. Epigenetics is an important mechanism through which early-life factors are thought to influence biological function, with long-term consequences. We describe a series of epigenetic studies designed to understand how early-life adversity results in stunting and to inform the development of practical tools such as predictive markers and therapeutic targets. This work is part of the UKRI GCRF Action Against Stunting Hub., Methods and Analysis: The project-in India, Indonesia and Senegal-comprises an observational study of mothers, fathers, and offspring (n=500) spanning the first 1000 days of life, and an intervention study in each country. Epigenetic status (DNA methylation) is determined in saliva from babies collected within 1 month of birth and again at 18 months of age, and from mothers and fathers around the time of birth. Epigenome-wide analysis is carried out using the Illumina EPIC array, augmented by high-definition sequencing approaches. Statistical analysis is carried out at the level of candidate genes/regions, higher dimensional epigenetic states and epigenome-wide association. Data analysis focuses on the determinants of stunting, the effectiveness of interventions, population comparisons and the link between epigenetics and other thematic areas, which include anthropometry, microbiome, gut health, parasitology, cognition, nutrition, food hygiene and water sanitation, food systems and the home environment., Ethics and Dissemination: This study has been approved by the relevant Ethics Committees in Indonesia, India and Senegal, and the UK. Research data will be published and posted in public repositories., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024. Re-use permitted under CC BY.

Introduction: Child stunting has a complex aetiology, especially in the first 1000 days of life. Nutrition interventions alone have not produced expected impacts in reducing/preventing child stunting, indicating the importance of understanding the complex interplay between environmental, physiological and psychological factors influencing child nutritional status. This study will investigate maternal and child nutrition, health and well-being status and associated factors through the assessment of: (1) anthropometry, (2) biomarkers of nutrition and health status, (3) dietary intakes, (4) fetal growth and development, (5) infant morbidity, (6) infant and young child feeding (IYCF) and (7) perinatal maternal stress, depression and social support., Methods: This study will be conducted in a prospective pregnancy cohort in India, Indonesia and Senegal. Pregnant women will be recruited in the second (Indonesia, Senegal) and third (India) trimester of pregnancy, and the mother and infant dyads followed until the infant is 24 months of age. During pregnancy, anthropometric measures will be taken, venous blood samples will be collected for biochemical assessment of nutrition and health status, dietary intakes will be assessed using a 4-pass-24-hour dietary recall method (MP24HR), fetal ultrasound for assessment of fetal growth. After birth, anthropometry measurements will be taken, venous blood samples will be collected, MP24HR will be conducted, infant morbidity and IYCF practices will be assessed and a sample of breastmilk will be collected for nutrient composition analyses. Perinatal maternal stress, depression, social support and hair cortisol levels (stress) will be measured. The results from this study will be integrated in an interdisciplinary analysis to examine factors influencing infant growth and inform global efforts in reducing child stunting., Ethics and Dissemination: Ethical approval was granted by the Ethics Committee of the London School of Hygiene and Tropical Medicine (17915/RR/17513); National Institute of Nutrition (ICMR)-Ministry of Health and Family Welfare, Government of India (CR/04/I/2021); Health Research Ethics Committee, University of Indonesia and Cipto Mangunkusumo Hospital (KET-887/UN2.F1/ETIK/PPM.00.02/2019); and the Comité National d'Ethique pour la Recherche en Santé, Senegal (Protocole SEN19/78); the Royal Veterinary College (URN SR2020-0197) and the International Livestock Research Institute Institutional Research Ethics Committee (ILRI-IREC2020-33). Results will be published in peer-reviewed journals and disseminated to policy-makers and participating communities., Competing Interests: Competing interests: none., (© Author(s) (or their employer(s)) 2024.

Purpose To study the fungal microbiome (mycobiome) and the virome of the lacrimal sacs in patients with primary acquired nasolacrimal duct obstruction (PANDO). Methods A prospective study was performed on 10 consecutive samples of the lacrimal sac contents obtained from patients with PANDO. The samples were obtained from the lacrimal sacs under endoscopy guidance and immediately transported on ice to the laboratory. Following DNA extraction and library preparation, a whole shotgun metagenome sequencing was performed on the Illumina platform (NOVASEQ 6000). The fungal internal transcript spacer analysis was performed using the PIPITS v2.7. The viral taxonomy profiling was performed using Kraken2 against the virus database. Results The taxonomic hit distribution across the lacrimal sac samples showed rich fungal diversity (4 phyla, 12 classed, 21 families and 26 genera). The major phyla were Ascomycota and Basidiomycota, and the key genera identified were Alternaria, Hyphopichia, Malassezia, Aspergillus and Epicoccum. The virome analysis identified 13 phyla, 15 classes and 27 families. The viruses were commonly from the families Poxviridae, Retroviridae, Siphoviridae and Myoviridae, Poxviridae being the most prevalent family. The BeAn 58058 virus, a member of the Poxviridae family, was the most abundant in all the samples. Conclusion The present study is the first whole metagenome sequencing exclusively of the fungal microbiome and virome from the lacrimal sacs of patients with PANDO.

Introduction Clinical debriefing (CD) improves teamwork and patient care. It is implemented across a range of clinical contexts, but delivery and structure are variable. Furthermore, terminology to describe CD is also inconsistent and often ambiguous. This variability and the lack of clear terminology obstructs understanding and normalisation in practice. This review seeks to examine the contextual factors relating to different CD approaches with the aim to differentiate them to align with the needs of different clinical contexts. Methods Articles describing CD were extracted from Medline, CINAHL, ERIC, PubMed, PsychINFO and Academic Search Complete. Empirical studies describing CD that involved two or more professions were eligible for inclusion. Included papers were charted and analysed using the Who-What-When-Where-Why-How model to examine contextual factors which were then used to develop categories of CD. Factors relating to what prompted debriefing and when debriefing occurred were used to differentiate CD approaches. Results Forty- six papers were identified. CD was identified as either prompted or routine, and within these overarching categories debriefing was further differentiated by the timing of the debrief. Prompted CD was either immediate or delayed and routine CD was postoperative or end of shift. Some contextual factors were unique to each category while others were relatively heterogeneous. These categories help clarify the alignment between the context and the intention of CD. Conclusions The proposed categories offer a practical way to examine and discuss CD which may inform decisions about implementation. By differentiating CD according to relevant contextual factors, these categories may reduce confusion which currently hinders discourse and implementation. The findings from this review promote context-specific language and a shift away from conceptions of CD that embody a one-size-fits-all approach. [ABSTRACT FROM AUTHOR]

As the healthcare community increasingly harnesses the power of generative artificial intelligence (AI), critical issues of security, privacy and regulation take centre stage. In this paper, we explore the security and privacy risks of generative AI from model-level and data-level perspectives. Moreover, we elucidate the potential consequences and case studies within the domain of ophthalmology. Model-level risks include knowledge leakage from the model and model safety under AI-specific attacks, while data-level risks involve unauthorised data collection and data accuracy concerns. Within the healthcare context, these risks can bear severe consequences, encompassing potential breaches of sensitive information, violating privacy rights and threats to patient safety. This paper not only highlights these challenges but also elucidates governance-driven solutions that adhere to AI and healthcare regulations. We advocate for preparedness against potential threats, call for transparency enhancements and underscore the necessity of clinical validation before real-world implementation. The objective of security and privacy improvement in generative AI warrants emphasising the role of ophthalmologists and other healthcare providers, and the timely introduction of comprehensive regulations.

Background Temporal structuring Is determined by practices and social norms and affects the quality and timing of care. In this case study of hyperacute stroke wards which provide initial stroke investigation, treatment and care, we explored temporal structuring patterns to explain how these may affect quality of care. Methods This paper presents a thematic analysis of qualitative interviews with hyperacute stroke staff (n=76), non-participant observations (n=41, ~102 hours) and documentary analysis of the relevant service standards guidance. We used an inductive coding process to generate thematic findings around the concept of temporal structuring, with graphically illustrated examples. Results Five temporal structures influence what- happens-when: (1) clinical priorities and quality assurance metrics motivate rapid activity for the initial life-prolonging assessments and interventions; (2) static features of ward organisation such as rotas and ward rounds impact consistency of care, determining timing and quality of care for patients; (3) some services experimented with staff rotas to try to meet peaks in demand, sometimes unsuccessfully; (4) implicit social norms or heuristics about perceived necessity affected staff motivation to make changes or improvements to consistency of care, particularly around weekend work; and (5) after-effects such as bottlenecks or backlogs affect quality of care, which are hard to measure effectively to drive service improvement. Conclusions Patients need temporally consistent high quality of care. Temporal consistency stems from the design of services, including staffing, targets and patient pathway design as well as cultural attitudes to working patterns. Improvements to consistency of care will be limited without changes to structures such as rotas and ward rounds, but also social norms around weekend work for certain professional groups.

Introduction Current international standards in consent to surgery practices are usually derived from health systems in Western countries, while little attention has been given to other contexts such as sub-Saharan Africa (SSA), despite this region facing the highest burdens of disease amenable to surgery globally. The aim of this study was to examine how the concept of informed consent for surgery is interpreted and applied in the context of SSA, and factors affecting current practices. Methods A systematic search of Medline, Embase and African Journal OnLine databases as well as grey sources was executed in May 2023 to retrieve relevant literature published since 2010 in English language against a set of given criteria. The socioecological framework for health was used for organising and summarising the identified evidence. Results A total of 27 papers were included in the review. Findings revealed that consent to surgery practices is generally substandard across SSA and the process is not adequate. Patients' understanding of informed consent is limited, likewise awareness of their rights to decision-making. A range of factors at the individual, interpersonal, institutional and system/societal levels affect the informed consent process. Conclusion There is a need to find more culturally acceptable and ethical ways to include the participation of patients in the decision-making process for surgical treatment in the SSA and define standards more closely aligned with the local context.

Background/aims Recent work has called into question the ability of visual acuity (VA) to accurately represent changes in visual function in infantile nystagmus (IN). This systematic review investigated factors affecting visual performance in IN, to guide development of suitable alternatives to VA. Methods Included studies used an experimental manipulation to assess changes in visual function in people with IN. Interventional studies, case series and case studies were excluded. Six databases were searched in August 2023. Selection, detection, attrition and measurement bias were assessed. Due to heterogeneous methodologies, narrative synthesis was undertaken. Results Eighteen relevant papers were identified, 11 of which complied with the review criteria. Articles were grouped according to the factor manipulated to evoke within-participant changes in performance (motion blur, psychological state, gaze angle or visual crowding). Optotype, image, grating and moving stimuli have been employed under varying lighting conditions and exposure duration. Conclusion Several factors affecting visual performance should be considered when assessing visual function in IN. While maximum VA is a useful metric, its measurement deliberately minimises nystagmus-specific factors such as changes in visual performance with gaze angle and the 'slow to see' phenomenon. Maximum VA can be measured using the null zone, providing unlimited viewing time, reducing stress/mental load and minimising visual crowding. Gaze-dependent functional vision space is a promising measure which quantifies the impact of the null zone but does not consider temporal vision. Although no complete measurement technique has yet been proven, this review provides insights to guide future work towards development of appropriate methods. [ABSTRACT FROM AUTHOR]

In this paper, we report the case of a boy in early childhood who presented with iron-deficiency anaemia, initially thought to be nutritional, who had a subsequent diagnosis of idiopathic pulmonary haemosiderosis (IPH). This is a slowly progressive and life-threatening disorder and is of paramount importance that this is identified early and treated appropriately. His first chest CT was not typical for IPH, and this appearance should be highlighted (small cystic changes alone initially). He also had focal disease, which allowed us to make the diagnosis using CT-guided biopsy. During his treatment, he experienced an uncommon side effect to a commonly prescribed medication (bradycardia with methylprednisolone). Since starting azathioprine as a steroid-sparing agent, he has been doing well. [ABSTRACT FROM AUTHOR]

Conventional operative dental procedures are being revisited with an approach that seeks to preserve the original tissue as much as possible. Implant dentistry has also seen the advent of various techniques which make minimal alteration to natural tissue. The flapless technique involves implant placement either through a freshly extracted socket or through a tansmucosal punch hole, without elevating mucoperiosteal flap. This paper presents a report on three cases of patient centric, conventional dental implant-based full-mouth rehabilitation, which was successfully carried out using the flapless technique, under varied clinical situations. Each case showed a favourable outcome in terms of restoration of the form and function of the patient’s dentition. [ABSTRACT FROM AUTHOR]

A girl in the early adolescent age group presented with multisystem manifestations in the form of periodic fever, recurrent abdominal pain, hypertension, seizure, skin lesions over the chest and gangrene over the left ring and middle fingertips. Her condition had remained undiagnosed for 11 years. On evaluation, she had features of polyarteritis nodosa (PAN) (multiple aneurysms, symmetric sensorimotor peripheral neuropathy, superficial ulcers, digital necrosis, myalgia, hypertension and proteinuria). As childhood PAN is a phenocopy of adenosine deaminase 2 with a different management strategy, whole-exome sequencing was performed, which revealed a pathogenic variant in ADA2 gene. The child was treated with TNF alpha inhibitors and showed improvement in the Paediatric Vasculitis Activity Score. The paper highlights the gratifying consequences of correct diagnosis with disease-specific therapy that ended the diagnostic odyssey, providing relief to the patient from debilitating symptoms and to the family from the financial burden of continued out-of-pocket health expenditure.
