Information dissemination and preservation are crucial for societal progress, especially in the technological age. While technology fosters knowledge sharing, it also risks spreading misinformation. Audio deepfakes—convincingly fabricated audio created using artificial intelligence (AI)—exacerbate this issue. We present Sonic Sleuth, a novel AI model designed specifically for detecting audio deepfakes. Our approach utilizes advanced deep learning (DL) techniques, including a custom CNN model, to enhance detection accuracy in audio misinformation, with practical applications in journalism and social media. Through meticulous data preprocessing and rigorous experimentation, we achieved a remarkable 98.27% accuracy and a 0.016 equal error rate (EER) on a substantial dataset of real and synthetic audio. Additionally, Sonic Sleuth demonstrated 84.92% accuracy and a 0.085 EER on an external dataset. The novelty of this research lies in its integration of datasets that closely simulate real-world conditions, including noise and linguistic diversity, enabling the model to generalize across a wide array of audio inputs. These results underscore Sonic Sleuth’s potential as a powerful tool for combating misinformation and enhancing integrity in digital communications. Full article

Dengue and other arboviruses remain a global threat, and enhanced efforts to control the mosquitoes that transmit them are urgently needed. A survey of potential manmade Aedes aegypti (L.) and Aedes albopictus (Skuse) oviposition containers was performed in four communities near the end of the typical dry season in 2018 in Trinidad, West Indies. The purpose was to conduct individual premise surveys and use GIS mapping to visualize premises within communities that had Aedes-positive containers, as this information could be used for the prioritization of mosquito control efforts in potential high risk areas as the wet season progressed. Accessible premises were surveyed following standard inspection protocols used by the Insect Vector Control Division (IVCD), Ministry of Health (MOH). The results indicated that two of the four locations would be at high risk for arbovirus transmission going into the wet season. The GIS mapping of premises with Aedes-positive containers facilitated the identification of potential hot spots for arbovirus transmission risk within communities that should be prioritized for enhanced monitoring and vector control efforts, emphasizing the need to increase community participation in standard surveys by IVCD.

COVID-19 vaccination is a critical public health measure to control the pandemic, but disparities in vaccination uptake remain a concern. This study investigates the determinants of COVID-19 vaccination among Korean adults using the Andersen model. Data from 231,784 participants in the community health survey were analyzed using chi-square testing and logistic regression. The risk of non-vaccination was higher among those aged 19–64 (95% CI: 1.52–1.74), males (95% CI: 1.11–1.24), the unemployed (95% CI: 2.21–2.47), unmarried individuals (95% CI: 1.12–1.24), those with unmet healthcare needs (95% CI: 1.41–1.67), recipients of national basic livelihood guarantees (95% CI: 1.45–1.73), those with lower subjective health (95% CI: 1.20–1.30), individuals with depression (95% CI: 1.28–1.44), current smokers (95% CI: 1.13–1.30), and those skipping breakfast (95% CI: 1.04–1.16). Conversely, the risk was lower for those with less than a high school education (95% CI: 0.72–0.81), individuals with psychological concerns about infection (0.87, 95% CI: 0.82–0.92) or public criticism (0.91, 95% CI: 0.86–0.97), individuals with chronic diseases (95% CI: 0.64–0.72), and current alcohol consumers (95% CI: 0.52–0.58). These findings underscore the need for targeted intervention strategies and support systems to promote vaccination in vulnerable populations. Further research should explore the long-term impact of these interventions on vaccination uptake. Full article

This study investigates the presence of potentially toxic elements (PTEs) in lettuce (Lactuca sativa L.) grown in urban gardens in a highly industrialized city in Brazil and evaluates the effectiveness of different washing methods in reducing contamination. Ten elements (arsenic (As), barium (Ba), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), vanadium (V), and zinc (Zn)) were analyzed for their concentration, and a health risk assessment was performed. The results showed that Pb concentrations in lettuce from gardens near the Capuava Petrochemical Complex reached 0.77 mg kg⁻¹, exceeding both national and international safety limits. The most effective washing procedure involved the use of sodium hypochlorite, which reduced As by 46%, Pb by 48%, and V by 52%. However, elements such as Ba, Cd, Cr, and Ni showed limited reductions of less than 10% across all washing methods. Health risk assessments revealed a particular concern for children, with the total cancer risk (TCR) exceeding acceptable limits in some gardens. Isotopic analysis of Pb revealed that atmospheric pollution from gasoline emissions and industrial activities were the primary sources of contamination. The elevated levels of Pb, Cr, and As highlight the need for targeted health education in local communities, especially regarding the importance of proper washing techniques. Risk management strategies, including improved contamination control and public awareness, are crucial to minimize exposure to these harmful elements, particularly in vulnerable populations like children.

Background/objectives: Sarcopenia, characterized by the progressive loss of muscle mass and strength, poses significant risks to physical health, leading to a reduced quality of life (QoL), increased disability, and higher mortality rates among older adults. Early detection and intervention are crucial to prevent the cascading effects of sarcopenia, including falls, fractures, and hospitalization. This study determined an optimal cut-off point of the SarQoL^® score that can serve as an effective screening tool among community-dwelling Korean older adults. Methods: The study involved 451 South Korean older adults, assessing the correlation between SarQoL^® scores and sarcopenia as defined by the Asian Working Group for Sarcopenia (AWGS) criteria. Participants completed the Korean version of the SarQoL questionnaire. Results: Findings revealed that individuals diagnosed with sarcopenia had significantly lower SarQoL^® scores compared to non-sarcopenic participants, with a cut-off score of ≤58.5 providing good diagnostic accuracy (AUC = 0.768, sensitivity = 69.3%, specificity = 75.2%). Conclusions: These results underscore the questionnaire’s reliability and validity in screening for sarcopenia-related QoL impairment and its potential utility as a clinical tool. Implementing the SarQoL^® in routine assessments could improve clinical outcomes by enabling earlier and more precise identification of sarcopenia. Full article

The maritime sector is increasingly integrating Information and Communication Technology (ICT) and Artificial Intelligence (AI) technologies to enhance safety, environmental protection, and operational efficiency. With the introduction of the MASS Code by the International Maritime Organization (IMO), which regulates Maritime Autonomous Surface Ships (MASS), ensuring the safety of AI-integrated systems on these vessels has become critical. To achieve safe navigation, it is essential to identify potential risks during the system planning stage and design systems that can effectively address these risks. This paper proposes RA4MAIS (Risk Assessment for Maritime Artificial Intelligence Safety), a risk identification method specifically useful for developing AI-integrated maritime systems. RA4MAIS employs a systematic approach to uncover potential risks by considering internal system failures, human interactions, environmental conditions, AI-specific characteristics, and data quality issues. The method provides structured guidance to identify unknown risk situations and supports the development of safety requirements that guide system design and implementation. A case study on an Electronic Chart Display and Information System (ECDIS) with an AI-integrated collision avoidance function demonstrates the applicability of RA4MAIS, highlighting its effectiveness in identifying specific risks related to AI performance and reliability. The proposed method offers a foundational step towards enhancing the safety of software systems, contributing to the safe operation of autonomous ships. Full article

The aging population in Poland poses significant socioeconomic and health challenges, particularly regarding malnutrition among seniors. This study examines the impact of place of residence on the nutritional status and related health outcomes of older adults. Data were collected from 338 community-dwelling seniors and those in long-term care facilities. The results indicate that long-term care residents exhibited significantly higher frailty and depression levels and poorer nutritional status, functional fitness, gait, and balance compared to those in communities. Self-reported quality of life did not differ significantly between groups. Regardless of residence, having a family correlated with better nutritional status, quality of life, and functional fitness and lower frailty and depression levels. Malnutrition was significantly associated with reduced functional fitness across all residences, and well-nourished individuals in care facilities had lower functional fitness than those who were at home. Community-dwelling residents had significantly lower frailty levels, with frailty negatively correlating with nutritional status. Normal nutritional status was linked to higher balance and gait scores, indicating a lower fall risk, with the risk further reduced for those living in community settings. Additionally, normal nutritional status correlated with lower depression levels and higher quality of life, with malnourished individuals experiencing better quality of life in community-dwelling settings. These findings underscore the critical role of residence and family support in elderly nutrition and health outcomes. Full article

In the conditions of growing anthropogenic pressure, aquatic ecosystems all over the world are subject to transformation, expressed in the growth of eutrophication, increase in acidity, changes in water exchange, etc. In the region of Eastern Siberia we studied, located in Yakutia in the middle reaches of the Lena River basin, there is a significant population growth accompanied by advancements in agriculture and public utilities. The region is rich in small lakes, which have been under pressure from human activities for the past few decades. The studied region is located in the permafrost zone and is characterized by severe climatic conditions, cold long winters, short hot summers, and a short ice-free period on reservoirs. We studied 17 lakes of various genesis, with varying degrees of anthropogenic pressure, located in the largest city of the region, small villages, and at different distances from them. Previous studies have established that cyanobacteria constitute the phytoplankton main group in these lakes during the summer period. Therefore, we selected them as the focus for our bioindication analysis. An integrated assessment of the bioindication properties of cyanobacteria, along with chemical water parameters, was undertaken using statistical mapping methods, JASP, and Redundancy Analysis (RDA). This analysis revealed the impact of urbanized areas, characterized by a decrease in pH, runoff of nitrogen compounds, and an increase in organic matter. Despite the cryolithozone harsh conditions, in small lakes of urbanized areas, cyanobacteria exhibit their competitive advantages within the plankton community. The prospect of continuing our work is associated with the need to determine the risk of cyanoHAB development since potentially toxic cyanobacteria have a mass development in a number of lakes.

Background: Since 2008, several cases of pregabalin abuse have been reported to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA). Despite this evidence, gabapentinoids are increasingly being prescribed. Moreover, pregabalin is being used in a recreational setting for its dissociative effects and euphoria. Objectives: To assess the characteristics of non-therapeutic users of pregabalin and to show behavioral trends associated with requests for the medicine at community pharmacies. Methods: The Medicine Abuse Observatory (MAO), an epidemiological surveillance system, was able to analyze trends about the most diverted drugs and the behavioral patterns of the population from community pharmacies. We have conducted an observational and cross-sectional study from January 2022 to April 2023, to determinate trends in the behavior of patients who have requested pregabalin in the Catalan Sephanet. Results: Behavior with respect to sex was similar in all health problems, although one difference was raised when considering neuropathic pain, in which the females were more involved (72.7%), especially around 2.5 times more than the males (27.3%, p < 0.05). The study showed a potential recreational use related to patients aged <25 years and patients aged 25–35 years (p < 0.05). Neuropathic pain was mainly identified in patients >65 years. In 75% of the cases, there was a preceding prescription. Conclusions: This study underlines the evidence of non-therapeutic use of pregabalin among the Catalan population and the need to take control measures. Actions should be promoted, both at the level of prescription and dispensing, and focusing on education and knowledge about the risks that may appear with the use of pregabalin. Full article

Access to credit plays an important role in the adoption of modern agricultural practices, such as better seeds, pesticides, and fertilizers, as well as in the sustainable utilization of land by smallholder farmers. This study explores the dynamics of smallholders’ access to and utilization of informal credit to manage local farming systems. The data were collected from rural households in the Dir Kohistan mountainous region of Pakistan in 2021. A bivariate probit model was employed to analyze the data from 300 randomly selected farming households. Our findings indicate that a significant proportion of respondents (70%) reported having access to informal credit, with 65% actively utilizing credit to bolster the economic viability of their farms. This study reveals various strategies that farmers employ in response to credit constraints. The majority of farmers (69%) prioritize meeting their own farm/household needs. Social networks, particularly friends, emerge as key sources of informal credit (58.1%). The results of the bivariate probit regression analysis identify positive relationships with fellow farmers and neighbors/relatives, along with a lower perceived risk, as the most significant factors influencing access to and utilization of informal credit. Therefore, our study recommends the promotion of relationships and linkages among farmers through facilitated networking events, introducing risk mitigation measures and promoting financial literacy programs to empower smallholder capacities on the credit market. Policymakers are urged to recognize the role of social relationships and consider policies that promote community credit practices for the overall financial well-being of farmers, especially in more isolated mountain areas.

Background: Colombian migration globally has had many consequences. This study focuses solely on the smoking behavior of Colombian migrants. This study addresses how the act of international migration impacts the likelihood of smoking among Colombian migrants. Smoking has been found to be the leading cause of preventable death, and so it is a health risk for Colombian migrants. This study pertains to the communities sampled in Colombia, where the migrants originated. Methods: This study uses the Latin American Migration Project to address how migration impacts the smoking behavior of Colombian migrants. Using logit regression, the statistical analysis predicts the likelihood of smoking among Colombian migrants. This study compares the smoking behavior of current and former Colombian migrants, which is compared to that of Colombian non-migrants. Because current and former migrants were surveyed, the study is able to control for health selectivity. Results: After accounting for health selectivity, the study finds that migration, as measured by time abroad, is positively and significantly related with the smoking of migrants relative to non-migrants. Additionally, this study shows that former migrants are more likely to smoke than current migrants, providing support for the salmon effect. Conclusion: This study adds to the literature on smoking by studying an understudied group, Colombian migrants, and provides a better measure of the impact of migration on smoking behavior by accounting for health selectivity and the salmon bias. The findings are consistent with assimilation theory, as more time abroad is associated with negative health behaviors that are common in the culture of the receiving country, but the fact that such behaviors are harmful to the migrant is consistent with the immigrant health paradox.

Depression is a leading cause of disability in the United States. Previous research has shown that added sugar consumption and stress are both risk factors for depression. Despite evidence that stress predicts added sugar consumption, and both affect the HPA axis, no research has explored how stress, added sugar consumption and depression are related. In this study, we investigated the possible effects of total added sugar and sugar-sweetened beverage consumption on depression, as well as their potential interactions with chronic stress. Measures of sugar consumption, chronic stress and depression were taken in an adult community sample at two time points. We hypothesized that high sugar consumption would predict more depression even after stress was statistically adjusted for, but that stress would moderate the relationship between added sugar consumption and depressive symptoms, amplifying the effect. We found that both total sugar consumption and sugar-sweetened beverage consumption at baseline predicted depressive symptoms one month later. However, only sugar-sweetened beverage consumption was a significant predictor of depression after controlling for stress, possibly because stress is related to diet quality. Stress did not moderate the relationship between added sugar consumption and depressive symptoms. These results suggest that stress should be included in future research on sugar and depression.

Asbestos, also known by its commercial name “amianthus”, has been widely used in various industries due to its unique properties. However, the extensive use of asbestos has had serious consequences for human health, most notably asbestosis, an irreversible chronic lung disease. Asbestosis increases the risk of lung cancer and malignant mesothelioma, both of which are fatal. Applied sciences such as microscopy (optical and scanning electron microscopy) and geochemistry have been fundamental in characterizing the mineral fibers of asbestos to understand its role in human health. We previously used these techniques to characterize these fibers; in this study, we explored the issues associated with asbestos and asbestosis, as well as the challenges facing science communication strategies in effectively informing society and workers about these risks. The lack of scientific culture, in general, has led to a lack of public awareness of the risks of asbestos. As such, effective communication and outreach plans and strategies, including the visualization of the fibers to demonstrate why problems arise if inhaled, must be implemented to address these challenges. Educational campaigns, guidelines, and plans that are informative and actionable, teaching workers, communities, and the public about the risks of asbestos are crucial. A general knowledge of mineralogy and geochemistry is needed, and providing and disseminating proper scientific communication may help to close the knowledge gap. We use examples and experience from Spain and Italy to illustrate this matter, as we have been working on the characterization of ultramafic complexes in these countries for more than ten years. Additionally, because these countries have strict laws for asbestos-containing materials, they are currently involved in retiring and demolishing buildings and infrastructure that contain asbestos.
