The factors influencing dengue virus (DENV) transmission by the Aedes aegypti mosquito vector in Latin America and the Caribbean (LAC) are complex and related. The use of a systems thinking, Ecohealth approach for understanding the dynamic linkages between all the ecological, biological, and social (eco-bio-social) factors associated with DENV epidemiology is imperative to better understand the DENV epidemiological system (episystem). The aim of this scoping review was to summarize the evidence for the relationships between the eco-bio-social factors influencing DENV vector dynamics, transmission, and epidemiological outcomes in LAC. The PubMed, SCOPUS, and LILACS databases were searched to collect relevant papers irrespective of design published in English, French, Portuguese, or Spanish. Full-text articles were obtained for the studies that passed the title and abstract screening process. The full-text articles were evaluated to determine if they met the eligibility criteria. Data were extracted using NVivo™ 12, and themes were compiled and communicated narratively. We included 68 studies from 13 different countries from LAC from the published literature from LAC between 2007 and 2022. Studies were classified as eco-biological (n = 24), bio-social (n = 21), eco-social (n = 14), or eco-bio-social studies (n = 9). Ten determinants emerged from the literature and were described, including: temperature; precipitation and humidity; artificial environment; vegetation and land cover; elevation and altitude; human population mobility and human activity; human population density and population demographics; chemical protective measures; seasonality and water storing practices; and urbanization and land use changes. We summarized the evidence on the eco-bio-social determinants of dengue transmission in LAC, with implications for comparable contexts in Asia and Africa. Key gaps remain regarding drivers of transmission and outcomes. Future research may benefit from using transdisciplinary research approaches to investigating Aedes-transmissible arboviruses.

In Guatemala, there is a significant gap in our understanding of the prevalence of antibiotic resistance across different reservoirs likely to affect human exposures. We conducted a One Health study of produce, poultry, water, and humans within peri-urban and urban Guatemalan markets to characterize the prevalence of third-generation cephalosporin-resistant Escherichia coli (3GCR-EC). We screened a total of 132 samples for 3GCR-EC using selective media. Samples were collected across three markets in Guatemala and included produce (n = 32), public tap water (n = 30), commercial and non-commercial poultry (n = 40), and human fecal matter (n = 30). We measured phenotypic and genotypic resistance using culture-based methods and whole-genome sequencing. Among the 132 samples, 87.1% (n = 115) were positive for E. coli, and 67.4% (n = 43) were positive for 3GCR-EC. After removing duplicates, a total of 40 3GCR-EC isolates were sequenced from commercial chicken carcasses (n = 8), non-commercial chicken carcasses (n = 16), water (n = 4), and human feces (n = 12). Out of 11 unique extended-spectrum beta-lactamase genes, the most prevalent gene was bla_CTX-M-55. There was high clonal diversity, with 32 distinct sequence types (ST) detected. Clinically important pandemic lineages of E. coli were identified: ST10, ST648, and ST410. This study identified a high prevalence of antibiotic resistance across diverse samples within public Guatemalan markets. The frequent detection of 3GCR-EC, their resistance genes, and epidemiologically important lineages of E. coli identified from humans, produce, water, and poultry samples highlight the importance of implementing more extensive surveillance using a One Health approach to develop coordinated strategies to mitigate the spread of antibiotic resistance.

Solastalgia refers to the emotional reactions of pain, lack of solace and isolation that individuals experience due to the environmental degradation of the area in which they live. Deterioration or rapid changes in the places where people live due to urbanization, disasters and various industrial initiatives, especially climate change, have made solastalgia an interdisciplinary research topic. Therefore, the aim of this study is to adapt the Solastalgia Scale into Turkish and examine its psychometric properties in a non-clinical sample. The study included 434 participants aged between 18 and 65 years. Participants responded to the Solastalgia Scale and the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5). According to the results of CFA, which examined the construct validity of the Turkish version of the scale, the original two-dimensional structure of the scale was confirmed and it was found that the factor loadings for the items in the Solace dimension ranged between .463 and .687, and the factor loadings for the items in the Algia dimension ranged between .811 and .922. SOS criterion validity, SOS total and its sub-dimensions and its relationship with the PCL-5 scale and its sub-scales were examined. According to the results of the correlation analysis, a moderate and positive significant relationship was found between SOS total and sub-dimensions and PCL-5 total and sub-dimensions. In addition, it was observed that all items of the SOS did not differ according to gender in terms of the answers given. Cronbach's Alpha, McDonald's Omega and Guttmann's Lambda values were examined for the reliability analysis of SOS. The values obtained as a result of the reliability analysis of the scale support the conclusion that both the total (α = .84; ω = .83, λ = .86) and the sub-dimensions of Solace (α = .77; ω = .77, λ = .77) and Algia (α = .90; ω = .91, λ = .87) have a very high level of reliability. In conclusion, according to the psychometric analyses, the Turkish version of the SOS was found to be reliable and valid. The scale is suitable for use with Turkish-speaking adults.

The COVID-19 pandemic has exposed systemic vulnerabilities and inequities across global health systems, emphasizing the urgent need for holistic, adaptive strategies in the post-pandemic era. This study introduces an integrated population health framework grounded in the One Health paradigm, addressing the complex interplay between human, animal, and environmental health. The proposed framework encompasses four key dimensions-social governance, behavioral control, health system adjustments, and environmental governance-designed to align health priorities across sectors and scales. By incorporating multi-sectoral collaboration, evidence-based risk factor analysis, and multidimensional health indicators, this model offers actionable strategies for enhancing health equity, system resilience, and long-term sustainability. The framework is especially relevant to addressing the dual burden of chronic disease and emerging infectious threats, while simultaneously responding to climate-related and socio-environmental risks. Our findings support the need for integrated governance and cross-disciplinary partnerships to advance planetary health objectives and inform national and global health policy.

Background: Eco-distress shows positive correlations with mental health impairments. However, the correlations reported by different studies vary widely. The aim of our review was to explore possible methodological sources for this heterogeneity, hereby deepening our understanding of eco-distress and its relationship with mental health.

Methods: Following PRISMA guidelines, Academic Search Complete, PubMed, PsycInfo, and Web of Science were searched on 15.03.2025 for publications reporting the initial development of instruments assessing eco-distress, subsequent validation studies, or correlations with mental health impairments. We analyzed the relationship of psychometric quality and the range of effect sizes descriptively, as well as the potential influence of the type of mental health questionnaire, the psychometric quality, and study and sample characteristics statistically as moderators in meta-analysis.

Results: We included 87 studies reporting on 15 different instruments. The underlying definitions of eco-distress differed and psychometric quality was mixed. However, confidence intervals did not vary systematically due to psychometric quality. Overall, eco-distress and mental health impairments correlated with r = 0.32, 95% CI [0.27; 0.37]. Only type of mental health questionnaire moderated the effect size.

Conclusion: Although it varied in magnitude, there was a significant positive correlation between eco-distress and mental health impairments. However, type of eco-distress questionnaire did not systematically influence the effect size. The heterogeneity was considerable and could only be partially explained by the moderators used. Future research should focus on the psychometric evaluation of existing instruments, as information on psychometric quality was incomplete for many instruments.

Batrachochytrium dendrobatidis (Bd) is a fungal pathogen responsible for amphibian population declines worldwide. In Mexico, understanding the potential distribution of Bd is crucial for conservation. Here, we developed an ecophysiological suitability index that integrates five key physiological parameters related to temperature. The environmental variables from WorldClim v2.1 were used to derive spatial representations of Bd's thermal responses. A multicriteria evaluation combined these parameters into an ecophysiological suitability index. This index was projected to 2050 and 2070 under two contrasting climate change scenarios. We also analyzed the overlap between Bd's suitability, natural protected areas (NPAs), and endemic amphibian geographic distributions to assess conservation implications. Our results indicate that Bd suitability is highest in the mountainous regions of central Mexico and declines significantly in coastal and lowland areas. By 2050 and 2070, both climate change scenarios predict reduced suitability across most of Mexico. Thirty-five percent of federal NPAs and 53% of state NPAs had high suitability for Bd. Endemic amphibians inhabiting mountains face greater suitability for Bd in their habitats. Our findings highlight the utility of mechanistic models for predicting pathogen distributions under environmental constraints. This approach provides actionable insights for prioritizing conservation efforts, including habitat management and amphibian population monitoring.

The global acceptance of the One Health (OH) approach has surged over the past two decades, leading to a proliferation of OH-related activities. A consequence of this growth is the increase in discipline-specific terminologies emerging in the OH lexicon to become lingua franca. However, some of these terms are used ambiguously, and interpreted broadly, thereby hampering systematic OH coordination. This article elucidates the semantics of eight fundamental terminologies, including 'One Health', 'One Health Systems', 'One Health Framework', 'One Health Core Competency', 'One Health Education/Curriculum', 'One Health Professional/Workforce', 'One Health Study/Research', and 'One Health Governance/Legislation'. The major findings of this study are that while there is a consensus on OH definition and OH framework usage, OH systems remain ambiguous despite frequent mentions. Core competencies and educational models are disparate, thus requiring harmonization, and a putative global OH governance structure is being defined through international organizations.
