Global health faces the triple challenge of preparing for future pandemics while responding to current ones in the midst of a climate crisis. In this commentary, we discuss the heightened focus on pandemic preparedness after the COVID-19 pandemic and the risks that this may pose to addressing the elimination of AIDS, tuberculosis, hepatitis and malaria, established in the Sustainable Development Goals as target 3.3. Considering their interconnections with the climate crisis and advocating for global health justice, we identify impasses that such a dispute over priorities can imply, and comment on four fronts of actions that could contribute convergently to both agendas as well as to facing the consequences of climate change to health: strengthening health systems, global commitment to equitable access to strategic medicines, addressing social inequalities and joining efforts for health and climate justice We conclude that addressing these fronts safeguards the health rights of the most vulnerable to existing epidemics while enhancing readiness for future pandemics. Moreover, solutions must transcend technocratic approaches, necessitating the confrontation of inequalities perpetuated by systems of power and privilege fueling both health and climate crises. Ultimately, health justice should guide responses to this intricate triple global health challenge.

Background: Human Papillomavirus (HPV), a prevalent sexually transmitted infection carrying significant risks ranging from benign lesions to various types of malignancies, represents a matter of great public health concern. Notably, most Arab countries lack public awareness campaigns or national immunization programs. This study aims at assessing the overall knowledge on HPV and HPV vaccination among the Lebanese population, exploring the prevalent attitude on the matter, and identifying barriers and misconceptions that prevent individuals from receiving the HPV vaccine.

Methods: A cross-sectional study was conducted in Beirut, on 201 participants aged between 18 and 36 years old. We performed ordinal analysis to assess the trend between Knowledge levels, attitude levels and hesitancy Levels.

Results: Majority of participants (77%) demonstrated a low level of knowledge on HPV vaccination, 50% held a positive attitude, with only 18.4% being already vaccinated. Negative trend was identified between levels of knowledge, attitude and hesitancy (gamma = -0.7415, p-value < 0.01; gamma= -0.58, p-value < 0.01 respectively). Unavailability or limited access to the vaccine, and misconceptions about HPV immunization were shown to be impeding vaccination.

Conclusion: Analysis of our results strongly suggests that improving knowledge and attitudes is likely to foster trust and reduce hesitancy, thereby promoting higher vaccine uptake.

The self-collection of vaginal swabs and point-of-care testing and treatment of sexually transmitted infections (STIs) is reported from several low-and middle-income countries. However, the reporting on women's experiences of self-collection and same-day testing and treatment of STIs is less well described. In this paper, we present the acceptability of self-collected vaginal swabs and point-of-care testing and treatment among pregnant women enrolled in a clinical trial (Women and Newborn Trial of Antenatal Intervention and Management - WANTAIM) in Papua New Guinea. Semi-structured interviews were conducted among 54 women enrolled into WANTAIM to identify the acceptability of the test and treat approach. Analysis of qualitative data used deductive and inductive thematic analysis applying Sekhon, Cartwright and Francis' acceptability theoretical framework. Most women reported that they understood that the vaginal swab was to identify infections that may affect their unborn baby; however, some were unsure about the specific infections they were being tested for. Among women who tested positive for an STI, some were unsure what they had been treated for. Overall, the self-collection of vaginal swabs for STI testing during pregnancy was highly acceptable.

There are many examples of poor TB infection prevention and control (IPC) implementation in the academic literature, describing a high-risk environment for nosocomial spread of airborne diseases to patients and health workers. We developed a positive deviant organisational case study drawing on Weick's theory of organisational sensemaking. We focused on a district hospital in the rural Eastern Cape, South Africa and used four primary care clinics as comparator sites. We interviewed 18 health workers to understand TB IPC implementation over time. We included follow-up interviews on interactions between TB and COVID-19 IPC. We found that TB IPC implementation at the district hospital was strengthened by continually adapting strategies based on synergistic interventions (e.g. TB triage and staff health services), changes in what value health workers attached to TB IPC and establishing organisational TB IPC norms. The COVID-19 pandemic severely tested organisational resilience and COVID-19 IPC measures competed instead of acted synergistically with TB. Yet there is the opportunity for applying COVID-19 IPC organisational narratives to TB IPC to support its use. Based on this positive deviant case we recommend viewing TB IPC implementation as a social process where health workers contribute to how evidence is interpreted and applied.

Establishing a robust One Health (OH) governance is essential for ensuring effective coordination and collaboration among human, animal, and environmental health sectors to prevent and address complex health challenges like zoonoses or antimicrobial resistance. This study conducted a mixed-methods environmental scan to assess to what extent Mexico displays a OH governance and identify opportunities for improvement. Through documentary analysis, the study mapped OH national-level governance elements: infrastructure, multi-level regulations, leadership, multi-coordination mechanisms (MCMs), and financial and OH-trained human resources. Key informant interviews provided insights into enablers, barriers, and recommendations to enhance a OH governance. Findings reveal that Mexico has sector-specific governance elements: institutions, surveillance systems and laboratories, laws, and policies. However, the absence of a OH governmental body poses a challenge. Identified barriers include implementation challenges, non-harmonised legal frameworks, and limited intersectoral information exchange. Enablers include formal and ad hoc MCMs, OH-oriented policies, and educational initiatives. Like other middle-income countries in the region, institutionalising a OH governance in Mexico, may require a OH-specific framework and governing body, infrastructure rearrangements, and policy harmonisation. Strengthening coordination mechanisms, training OH professionals, and ensuring data-sharing surveillance systems are essential steps toward successful implementation, with adequate funding being a relevant factor.

There is growing attention to the ways in which climate change may affect sexual health, yet key knowledge gaps remain across global contexts and climate issues. In response, we conducted a scoping review to examine the literature on associations between climate change and sexual health. We searched five databases (May 2021, September 2022). We reviewed 3,183 non-duplicate records for inclusion; n = 83 articles met inclusion criteria. Of these articles, n = 30 focused on HIV and other STIs, n = 52 focused on sexual and gender-based violence (GBV), and n = 1 focused on comprehensive sexuality education. Thematic analysis revealed that hurricanes, drought, temperature variation, flooding, and storms may influence HIV outcomes among people with HIV by constraining access to antiretroviral treatment and worsening mental health. Climate change was associated with HIV/STI testing barriers and worsened economic conditions that elevated HIV exposure (e.g. transactional sex). Findings varied regarding associations between GBV with storms and drought, yet most studies examining flooding, extreme temperatures, and bushfires reported positive associations with GBV. Future climate change research can examine understudied sexual health domains and a range of climate-related issues (e.g. heat waves, deforestation) for their relevance to sexual health. Climate-resilient sexual health approaches can integrate extreme weather events into programming.

Variations of Community Health Workers (CHWs) interventions in diabetes self-management education (DSME) have been reviewed by many studies. In contrast, specific interventions regarding foot care intervention (FCI) are scarce and need to be explored further as one preventive measure to reduce diabetic foot problems in the community. This scoping review aimed to identify, and report nature of FCIs and the core components of FCIs delivered by CHWs. The scoping review was undertaken using PRISMA Extension for Scoping Reviews (PRISMA-ScR). The following electronic databases were searched for articles from data first indicated date through December 2022: CINAHL, EMBASE, Cochrane, Scopus, Web of Science, Theses ProQuest, PubMed, google scholar and other sources by using search terms related to foot care, community health workers, and diabetes mellitus. Descriptive synthesis was used to summarise the data. Nine studies from 1644 were included. All studies found that CHWs provided DSME in general, and foot care education was included. There was no detailed description of the core components of the intervention on foot care. Although, all studies might not provide detailed data on how CHW provided FCIs; the CHW intervention is an undoubtedly vital strategy to promote and prevent foot problems in medically underserved communities.

Urban inequalities are exacerbated due to rapid urbanisation. This is also evident within slums in low- and middle-income countries, where high levels of heterogeneity amongst the slum population lead to differential experiences in Water, Sanitation, and Hygiene (WASH) and housing access. This scoping review provides evidence of the interconnection of WASH and housing and presents barriers to access and the consequences thereof for slum dwellers. It does so while considering the social stratification amongst urban slum dwellers and their lived experiences. A systematic search of journal articles was conducted in November 2022 in PubMed, Scopus, and Web of Science. A total of 33 papers were identified which were full text reviewed and data extracted. Infrastructure, social and cultural, socio-economic, governance and policy and environmental barriers emerged as general themes. Barriers to WASH and housing were more frequently described concerning women and girls due to gender norms within WASH and the home. Barriers to WASH lead to compromised health, socio-economic burdens, and adverse social impacts, thus causing residents of slums to navigate their WASH mobility spatially and over time. Insights from this review underscore the need for an intersectional approach to understanding access inequalities to WASH and housing.

Transfers between health facilities for postpartum women living with HIV are associated with disengagement from care. In South Africa, women must transfer from integrated antenatal/HIV care to general HIV services post-delivery. Thereafter, women transfer frequently e.g. due to geographic mobility. To explore barriers to transfer, we conducted in-depth interviews >2 years post-delivery in 28 participants in a trial comparing postpartum HIV care at primary health care (PHC) antiretroviral therapy (ART) facilities versus a differentiated service delivery model, the adherence clubs, which are the predominant model implemented in South Africa. Data were thematically analysed using inductive and deductive approaches. Women lacked information including where they could transfer to and transfer processes. Continuity mechanisms were affected when women transferred silently i.e. without informing facilities or obtaining referral letters. Silent transfers often occurred due to poor relationships with healthcare workers and were managed inconsistently. Fear of disclosure to family and community stigma led to transfers from local PHC ART facilities to facilities further away affecting accessibility. Mobility and the postpartum period presented unique challenges requiring specific attention. Information regarding long-term care options and transfer processes, ongoing counselling regarding disclosure and social support, and increased health system flexibility are required.

A growing body of evidence has shown the effects of poor preconception health on adverse pregnancy outcomes and, subsequently, maternal and child morbidity and mortality. However, the cost of poor preconception health remains relatively unexplored. Using the case of Nigeria, this study provides the first estimate of the disease and economic burden of poor preconception health at a country level. Using data from international databases and the scientific literature, the study used a cost-of-illness approach to quantify the foregone productivity and direct healthcare costs resulting from six preconception risk factors (adolescent pregnancy, short birth interval, overweight and obesity, intimate partner violence, female genital mutilation, folate deficiency). The results indicate that 6.7% of maternal deaths, 10.9% of perinatal deaths, and 10.5% of late neonatal deaths were attributable to the selected preconception risk factors in 2020. The economic burden of poor preconception health in Nigeria was estimated at US$ 3.3 billion in 2020, of which over 90% was generated by premature mortality. If prevalence rates remain constant, total economic losses could amount to US$ 46.2 billion by 2035. This analysis paves the way for further studies investigating the economic costs and benefits of preconception interventions and policies in low and middle-income countries.
