Introduction: The COVID-19 pandemic has worsened pre-existing vulnerabilities among older Syrian refugees in Lebanon, potentially impacting their mental health. The study aims to describe the evolution of poor mental health over time and to develop and internally validate a prediction model for poor mental health among older Syrian refugees in Lebanon.

Methods: This prognostic study used cross-sectional data from a multiwave telephone survey in Lebanon. It was conducted among all Syrian refugees aged 50 years or older from households that received assistance from a humanitarian organisation. Data were collected between 22 September 2020 and 20 January 2021. Poor mental health was defined as a Mental Health Inventory-5 score of 60 or less. The predictors were identified using backwards stepwise logistic regression. The model was internally validated using bootstrapping. The calibration of the model was presented using the calibration slope (C-slope), and the discrimination was presented using the optimised adjusted C-statistic.

Results: There were 3229 participants (median age=56 years (IQR=53-62)) and 47.5% were female. The prevalence of poor mental health was 76.7%. Predictors for poor mental health were younger age, food insecurity, water insecurity, lack of legal residency documentation, irregular employment, higher intensity of bodily pain, having debt and having chronic illnesses. The final model demonstrated good discriminative ability (C-statistic: 0.69 (95% CI 0.67 to 0.72)) and calibration (C-slope 0.93 (95%CI 0.82 to 1.07)).

Conclusion: Mental health predictors were related to basic needs, rights and financial barriers. These allow humanitarian organisations to identify high-risk individuals, organise interventions and address root causes to boost resilience and well-being among older Syrian refugees in Lebanon.

From the WHO's perspective, trained and motivated healthcare workers can promote community access to essential health services in deprived areas; this could also help achieve the millennium development goals. The concentration of healthcare workers in the capital has caused a lack of them in deprived areas and made delivering services difficult in almost all rural and underdeveloped areas. So, one of the main concerns of all health systems is planning to attract and keep physicians in underprivileged areas.The number of retained physicians has tripled.24/7 coverage of specialised medical services in the hospital has been provided.People's access to health care has improved.Dispatching of patients to other cities' hospitals for essential medical services has been minimised by providing it locally.Illegal payments have been eliminated.This practice study aims to present Iran's Universal Health Coverage approach to addressing the lack of access to physicians in deprived areas through the 'supporting physician retention in deprived areas' programme and demonstrate its outcomes from 2014 to 2016. This national programme is designed to improve people's access to high-quality health services and reduce out-of-pocket payments at hospitals in underdeveloped areas.The number of retained physicians has tripled.24/7 coverage of specialised medical services in the hospital has been provided.People's access to health care has improved.Dispatching of patients to other cities' hospitals for essential medical services has been minimised by providing it locally.Illegal payments have been eliminated.The programme began by ranking all the cities in the country based on socioeconomic indicators. Then, 302 regions in 30 provinces of Iran were selected and classified into four groups. Finally, each group's incentive package was defined, consisting of a combination of fixed and performance-oriented payments. This programme has obtained the following achievements in the deprived areas:The number of retained physicians has tripled.24/7 coverage of specialised medical services in the hospital has been provided.People's access to health care has improved.Dispatching of patients to other cities' hospitals for essential medical services has been minimised by providing it locally.Illegal payments have been eliminated.

Introduction: COVID-19 showed that countries must strengthen their operational readiness (OPR) capabilities to respond to an imminent pandemic threat rapidly and proactively. We conducted a rapid scoping evidence review to understand the definition and critical elements of OPR against five core sub-systems of a new framework to strengthen the global architecture for Health Emergency Preparedness Response and Resilience (HEPR).

Methods: We searched MEDLINE, Embase, and Web of Science, targeted repositories, websites, and grey literature databases for publications between 1 January 2010 and 29 September 2021 in English, German, French or Afrikaans. Included sources were of any study design, reporting OPR, defined as immediate actions taken in the presence of an imminent threat, from groups who led or responded to a specified health emergency. We used prespecified and tested methods to screen and select sources, extract data, assess credibility and analyse results against the HEPR framework.

Results: Of 7005 sources reviewed, 79 met the eligibility criteria, including 54 peer-reviewed publications. The majority were descriptive reports (28%) and qualitative analyses (30%) from early stages of the COVID-19 pandemic. Definitions of OPR varied while nine articles explicitly used the term 'readiness', others classified OPR as part of preparedness or response. Applying our working OPR definition across all sources, we identified OPR actions within all five HEPR subsystems. These included resource prepositioning for early detection, data sharing, tailored communication and interventions, augmented staffing, timely supply procurement, availability and strategic dissemination of medical countermeasures, leadership, comprehensive risk assessment and resource allocation supported by relevant legislation. We identified gaps related to OPR for research and technology-enabled manufacturing platforms.

Conclusions: OPR is in an early stage of adoption. Establishing a consistent and explicit framework for OPRs within the context of existing global legal and policy frameworks can foster coherence and guide evidence-based policy and practice improvements in health emergency management.

Since the 1970s, influential literature has been using famines as natural experiments to examine the long-term health impact of prenatal famine exposure at the individual level. Although studies based on various famines have consistently shown that prenatal famine exposure is associated with an increased risk of type 2 diabetes (T2D), no studies have yet quantified the contribution of famines to later-life T2D at the population level. We, therefore, synthesised findings from the famines in Ukraine 1932-1933, the Western Netherlands 1944-1945 and China 1959-1961 to make preliminary estimates of T2D cases attributable to prenatal famine exposure. These famines were selected because they provide the most extensive and reliable data from an epidemiological perspective. We observed a consistent increase in T2D risk among prenatally exposed individuals in these famines, which translated into about 21 000, 400 and 0.9 million additional T2D cases due to prenatal famine exposure in Ukraine, Western Netherlands and China, respectively. The T2D increase related to famine exposure represented only around 1% of prevalent T2D cases in these countries. Our observations highlight the significant increase in later-life T2D risk among individuals with prenatal famine exposure but also the limited contribution of prenatal famine exposure to T2D epidemics at the population level.

The need for the public to take an active role in scientific research is becoming increasingly important, particularly in health-related research. However, the coexistence and alignment of scientific and citizen interests, needs, knowledge and timing is not straightforward, especially when involving migrant populations. To conduct impactful research, it becomes also essential to consider the perspectives of policymakers, thereby adding a layer of complexity to the processes.In this article we address the experience of a living lab created in a research institution and supported by the city council and a local foundation, in which we developed three experiences of patient and public involvement (PPI): (1) accessing to comprehensive care for people at risk of Chagas disease; (2) strategies towards improving access and quality of mental healthcare services in migrants; (3) promoting healthy and safe school environments in vulnerable urban settings.These three challenges provided an opportunity to delve into diverse strategies for involving key stakeholders, including migrant populations, expert researchers and political actors in health research. This article offers insights into the successes, challenges, and valuable lessons learnt from these endeavours, providing a vision that can be beneficial for future initiatives. Each living lab experience crafted its unique governance system and agenda tailored to specific challenge scenarios, giving rise to diverse methods and study designs.We have found that the management of the cocreation of the research question and the institutional support are key to building robust PPI processes with migrant groups.

Introduction: Chlamydia trachomatis (Ct) and Neisseria gonorrhoeae (Ng) infections are often asymptomatic; screening increases early detection and prevents disease, sequelae and further spread. To increase Ct and Ng testing, several countries have implemented specimen self-collection outside a clinical setting. While specimen self-collection at home is highly acceptable to patients and as accurate as specimens collected by healthcare providers, this strategy is new or not being used in some countries. To understand how offering at home specimen self-collection will affect testing uptake, test results, diagnosis and linkage to care, when compared with collection in clinical settings, we conducted a systematic literature review and meta-analysis of peer-reviewed studies.

Methods: We searched Medline, Embase, Global Health, Cochrane Library, CINAHL (EBSCOHost), Scopus and Clinical Trials. Studies were included if they directly compared specimens self-collected at home or in other non-clinical settings to specimen collection at a healthcare facility (self or clinician) for Ct and/or Ng testing and evaluated the following outcomes: uptake in testing, linkage to care, and concordance (agreement) between the two settings for the same individuals. Risk of bias (RoB) was assessed using Cochrane Risk of Bias (RoB2) tool for randomised control trials (RCTs).

Results: 19 studies, from 1998 to 2024, comprising 15 RCTs with a total of 62 369 participants and four concordance studies with 906 participants were included. Uptake of Ct or Ng testing was 2.61 times higher at home compared with clinical settings. There was a high concordance between specimens collected at home and in clinical settings, and linkage to care was not significantly different between the two settings (prevalence ratio 0.96 (95% CI 0.91-1.01)).

Conclusion: Our meta-analysis and systematic literature review show that offering self-collection of specimens at home or in other non-clinical settings could be used as an additional strategy to increase sexually transmitted infection testing in countries that have not yet widely adopted this collection method.

Introduction: A data monitoring committee (DMC) is an independent group of experts who assess the ongoing scientific and ethical integrity of a study through periodic analyses of study data. The objective of this study was to explore the extent to which the structure, membership and deliberations of DMCs enable them to address ethical issues.

Methods: We conducted qualitative individual interviews (n=22) with DMC members from countries across Africa, the Americas, South Asia and the UK. We selected interview respondents through purposive sampling, managed data using NVivo (Release V.1.7) and analysed data thematically.

Results: All respondents were highly experienced professionals; many (18/22) had received training in medicine and/or statistics. One respondent had academic qualifications in ethics, and four indicated that they served on DMCs as ethicists. While respondents generally felt DMCs should be required for studies that were high-risk or enrolled vulnerable populations, some were concerned about the overuse of DMCs. There were divergent views on the necessity of geographical and disciplinary representation in DMC membership, including about whether ethicists were helpful. Many respondents described a DMC member recruitment process that they felt was somewhat exclusive. While one respondent received DMC-specific training, most described learning on the job. Respondents generally agreed that study protocols and DMC charters were key guiding documents for addressing ethical issues and described DMC deliberations that often, but not always, involved consensus-building.

Conclusion: This study is one of the first to consider the ethical implications of DMC structure, membership and deliberations. The potential overuse of DMCs, DMC member recruitment processes that seem somewhat insular, limited training for DMC members, and divergent approaches to deliberation may limit the capacity of DMCs for addressing ethical issues. Further research on DMC structure and processes could help enhance the ethical preparedness of DMCs.
