Exploring the use of meal delivery services in Belgium

Abstract Background Ready-to-eat meal delivery services have become commonplace in recent years and their growth accelerated during the COVID-19 pandemic. However, the potential ramifications on dietary habits and subsequent health outcomes remain largely unexplored. Given the well-established links between unhealthy dietary patterns and chronic diseases such as obesity, type II diabetes, and cardiovascular diseases, understanding the determinants and public health implications of ready-to-eat meal delivery services use is imperative. This study aims to investigate the determinants associated with the use of ready-to-eat meal delivery services and their implications for health behaviours and outcomes. Methods This cross-sectional study is conducted amongst adults residing in Flanders or Brussels, Belgium. A quantitative online survey commenced in April 2024 and is scheduled to conclude by June 2024. Structural equation models will be used to assess determinants and implications of ready-to-eat meal delivery services use. Latent class analysis will be used to identify user profiles and subsequent structural equation modelling will assess determinants of these profiles and their associated health (behaviour) outcomes. Results Preliminary results suggest meal delivery usage was higher in younger and middle-income users. Main reasons of use amongst users (n = 139) were more time for leisure activities (66%) and supermarket avoidance (64%). Main reasons for non-use amongst non-users (n = 69) were not wanting to spend money with meal delivery services (70%) and preference to cook own meals (81%). Data collection is currently ongoing. Further analysis is planned, and full results will be available by November 2024. Conclusions This study will provide a better understanding of drivers of meal delivery services use in Belgium and their potential impact on public health. It will also help inform public health strategies targeted at improving dietary habits. Key messages • Recognising that meal delivery services will become ever present in the future, insights into why people order meals for delivery and the potential health implications of such services are essential. • The use of advanced statistical techniques highlights the potential of the study to offer novel insights into determinants and ramifications of meal delivery services usage.

Intersectional inequalities in child social-emotional health: a case for proportionate universalism

Abstract Background Social-emotional difficulties in early childhood are associated with a range of outcomes across the life course and are related to socioeconomic factors. The aim of this study was to examine intersectional inequalities in social-emotional problems in preschool children relating to their parents’ income, education and country of birth in addition to investigating the public health implications. Methods This population-based study with a repeated cross-sectional design in the Västerbotten County of Sweden used the Ages and Stages Questionnaires: Social-Emotional (ASQ:SE) for children aged 3 in child health care services over the years of 2014-2018 and socio-economic information from national population registers. The effective sample of 8,823 individuals was analyzed using additive binomial regression in combination with an analysis of individual heterogeneity and discriminatory accuracy (AIHDA) approach to estimate risk differences for social-emotional problems across 27 intersectional groups and discriminatory accuracy. Results Average risk differences generally increased in the groups where multiple dimensions of social inequality intersected, with risk differences as high as 18% (95% CI 8 to 28%) and 25% (95% CI 14 to 37%) compared to the most advantaged category. The discriminatory accuracy of all three included regression models was estimated as moderate, but improved in a slight but statistically significant way with the addition of social inequalities. Conclusions This study increases our understanding of intersectional and social inequalities in social-emotional problems in preschool children. It supports the need for universal public health policies in addition to policies targeting more vulnerable groups when addressing this issue, consistent with the concept of proportionate universalism. An intersectional research perspective including discriminatory accuracy could increase our knowledge of health inequities and improve public health effectiveness. Key messages • Intersecting dimensions of social inequalities are associated with an increased risk of social-emotional problems in children aged 3. • Universal public health policies are needed in addition to policies targeting vulnerable population groups with regards to social-emotional problems in young children.

AUMENTO DO USO DE ANSIOLÍTICOS APÓS A PANDEMIA – REVISÃO DA LITERATURA

Introduction: Anxiety disorders are significant areas of research due to the high incidence of anxiety being diagnosed in the population, leading to temporary or permanent disability. Investigations conducted on the mental health of Brazilian residents during the COVID-19 outbreak indicate an increase in diagnoses of anxiety, depression, and stress. The deterioration of mental well-being was influenced by multiple factors, including the absence of proper funeral ceremonies, the escalation of unemployment, and the decline in financial capacity, which heightened tension and anguish among those needing a source of income to support their families. This scenario significantly contributed to the increase in the use of anxiolytics, as many individuals resorted to these medications as a form of immediate relief for the symptoms of anxiety and stress exacerbated by the pandemic, highlighting the need for a broader and more integrated approach to mental health treatment in the current context. Objectives: To analyze the increase in the use of anxiolytics after the COVID-19 pandemic and its implications for public health. Methodology: This study is structured as a literature review, aiming to compile and analyze existing information on the topic. Additionally, the research is exploratory and descriptive, with the objective of mapping existing knowledge on the subject and outlining its nuances. The platforms Scielo, Portal de Periódicos CAPES, and Medline were used. The period considered was from 2018 to 2023, with texts fully available online, in Portuguese. Results: The results indicate a significant increase in the use of anxiolytics during and after the COVID-19 pandemic, especially among more vulnerable groups, such as the elderly and people with pre-existing health conditions. The use of medications like Alprazolam increased by 35% in 2020, reflecting the intensification of anxiety in the population. Conclusion: The pandemic exposed the fragility of mental health systems, highlighting the need for public policies that combine pharmacological treatment with continuous support. Future research is essential to monitor the long-term effects of anxiolytic use in the post-pandemic period.

The power of artificial intelligence for managing pandemics: A primer for public health professionals.

Artificial intelligence (AI) applications are complex and rapidly evolving, and thus often poorly understood, but have potentially profound implications for public health. We offer a primer for public health professionals that explains some of the key concepts involved and examines how these applications might be used in the response to a future pandemic. They include early outbreak detection, predictive modelling, healthcare management, risk communication, and health surveillance. Artificial intelligence applications, especially predictive algorithms, have the ability to anticipate outbreaks by integrating diverse datasets such as social media, meteorological data, and mobile phone movement data. Artificial intelligence-powered tools can also optimise healthcare delivery by managing the allocation of resources and reducing healthcare workers' exposure to risks. In resource distribution, they can anticipate demand and optimise logistics, while AI-driven robots can minimise physical contact in healthcare settings. Artificial intelligence also shows promise in supporting public health decision-making by simulating the social and economic impacts of different policy interventions. These simulations help policymakers evaluate complex scenarios such as lockdowns and resource allocation. Additionally, it can enhance public health messaging, with AI-generated health communications shown to be more effective than human-generated messages in some cases. However, there are risks, such as privacy concerns, biases in models, and the potential for 'false confirmations', where AI reinforces incorrect decisions. Despite these challenges, we argue that AI will become increasingly important in public health crises, but only if integrated thoughtfully into existing systems and processes.

An Integrated Pathophysiological and Clinical Perspective of the Synergistic Effects of Obesity, Hypertension, and Hyperlipidemia on Cardiovascular Health: A Systematic Review.

This review paper explores the synergistic effects of obesity, hypertension (HTN), and hyperlipidemia on cardiovascular health by integrating pathophysiological and clinical perspectives. Obesity, characterized by excessive body fat, HTN, defined by elevated blood pressure, and hyperlipidemia, indicated by high blood lipid levels, are globally prevalent conditions that significantly increase the risk of cardiovascular diseases (CVDs). The interplay between these conditions exacerbates cardiovascular risk through mechanisms such as chronic inflammation, insulin resistance, endothelial dysfunction, arterial stiffness, and atherogenesis. This review synthesizes epidemiological evidence and highlights the prevalence and co-occurrence of these conditions, with an emphasis on their combined impact on cardiovascular health. The literature search encompassed various databases, and data extraction included key study characteristics and outcomes. The findings underscore the importance of integrated management strategies, involving lifestyle interventions, pharmacological treatments, and regular monitoring, to mitigate the heightened cardiovascular risk posed by these conditions. In addition, the various public health implications are addressed, advocating for community-based interventions and policy changes. Future research directions may include exploring novel therapeutic approaches, personalized medicine strategies, and longitudinal studies to enhance the understanding and management of the synergistic effects of obesity, HTN, and hyperlipidemia on cardiovascular health.

Impersonal Sex and Pornography: Potential Confounding, Moderation, and Implications for Public Health

ABSTRACT Following the recent exhortations of health communication scholars to continue the study of pornography and its potential impact on health-related behaviors, the present study investigated associations between the frequency of pornography use and six indicators of impersonal sex among a national probability sample of US adults. Impersonal sex has been linked to a variety of important public health outcomes, including STD risk and sexual aggression perpetration. In this study, pornography use was positively correlated with the likelihood of engaging in group sex, having sex with a casual partner, having sex without emotional intimacy, experiencing heightened sexual pleasure during non-relational sex, relational infidelity, and perceiving the receipt of sexual pleasure from others as the best thing about sex. No evidence emerged that these associations were spuriously due to high sex drive individuals being both more likely to consume pornography and engage in impersonal sex. But several were conditional on age. Most importantly, countering the conventional wisdom that sexual media are most likely to affect the sexual behavior of young audiences, the strength of the positive association between pornography use and the likelihood of engaging in group sex and casual dyadic sex was larger among older adults and weaker among younger adults.

Genomic adaptation of Clostridium perfringens to human intestine

AbstractClostridium perfringens is often associated with foodborne diseases, posing significant public health risks. However, genomic investigation of C. perfringens isolates from the human population has been lacking. This study aims to fill this knowledge gap by examining the genomic characteristics of C. perfringens isolates from 699 individuals at a provincial hospital in China. We further conducted evolutionary and pan‐genomic analyses, incorporating isolates from humans and animals worldwide. The results reveal potential regional and transregional transmission of C. perfringens among individuals, along with the common transfer of small gene clusters during this process. Notably, the food poisoning‐associated toxin gene cpe was identified in a fusion plasmid for the first time in an isolate, indicating fusion of pCP13‐like and pCW3‐like plasmids and the potential for transfer of cpe across genetic backgrounds. Moreover, we observed that the genomic characteristics of C. perfringens correlate with host species, with specific toxin genes, such as pfoA and colA, potentially influencing host selectivity. Through this comprehensive genomic analysis, we provide novel insights into the fusion of pCW3‐like and pCP13‐like plasmids, the genetic location of cpe, the transmission dynamics of C. perfringens strains, and the relationship between toxin genes and host relevance. These findings expand our understanding of C. perfringens and its implications for public health.

Cryptosporidium spp. Infection in Adult Kidney Transplant Patients: A Systematic Review and Meta-Analysis.

Background: Diarrhea frequently occurs after vascular organ transplantation, including kidney transplants. This may result from non-infectious factors, adverse effects of immunosuppressive medications, or infections caused by various pathogens, including viruses, bacteria, fungi, or parasites, for example, intestinal protozoan parasites such as Cryptosporidium spp., which are particularly dangerous for immunocompromised patients. Methods: This review is based on scientific articles sourced from validated databases such as PubMed, the National Center for Biotechnology Information (NCBI), ScienceDirect, and Google Scholar. The primary search was conducted on 12-13 July 2024, using the keywords 'Cryptosporidium' AND 'cryptosporidiosis' AND 'kidney' AND 'transplant' AND 'adult'. Inclusion criteria encompassed human studies, case reports, peer-reviewed journal publications, review articles, and research articles in English. Exclusion criteria included studies not in English, gray literature (e.g., conference proceedings and abstracts), and data related to pediatric patients (under 18 years old) and HIV patients. Results: This systematic review and meta-analysis have highlighted an often-overlooked connection between Cryptosporidium spp. infections in adult kidney transplant recipients (KTR). Furthermore, it includes an analysis of the clinical presentation, diagnosis, and treatment of Cryptosporidium spp. infection in these patients, based on available case reports. Our study demonstrates that adult kidney transplant patients are at a significantly higher risk of acquiring Cryptosporidium spp. compared to healthy participants. Conclusions:Cryptosporidium spp. infections can be asymptomatic, making it essential to screen both symptomatic and asymptomatic kidney transplant recipients. The clinical presentation of cryptosporidiosis typically involves digestive symptoms and can be complicated by biliary tract involvement. In KTR patients presenting with diarrhea, it is crucial to not only test for Cryptosporidium spp. but also to rule out bacterial and viral etiologies, including infections such as C. difficile, C. colitis, Clostridium spp., and rotavirus. The diagnosis of Cryptosporidium spp. infections primarily relies on microscopic methods, which are known for their low sensitivity. Therefore, diagnostic approaches should include both direct methods and, where possible, molecular techniques. Based on the analyzed cases, the most effective treatment results were achieved with reduction in immunosuppression if possible (strong, very low) and nitazoxanide at a dose of 500 mg twice daily for 14 days. Considering the public health implications of our findings, the current epidemiological data underscore the need for further research to develop effective prevention and intervention strategies against cryptosporidiosis. Preventive measures, regular screening programs, and the treatment of Cryptosporidium spp. infections should be integrated into the clinical care of transplant patients. It is also important that patients are informed about environmental risk factors.

Association between the levels of toxic heavy metals and schizophrenia in the population of Guangxi, China: A case-control study

The relationship between body levels of heavy metals and the risk of schizophrenia remains unclear. This study investigates the relationship between plasma levels of toxic heavy metals and the risk of schizophrenia among adults in Guangxi, China. Plasma concentrations of lead (Pb), cadmium (Cd), arsenic (As), and chromium (Cr) were measured using inductively coupled plasma mass spectrometry (ICP-MS). To evaluate both the single and combined effects of metal exposure on the risk of schizophrenia, we employed multivariate logistic regression, Bayesian Kernel Machine Regression (BKMR), and generalized Weighted Quantile Sum (gWQS) models. Additionally, we employed the Comparative Toxicogenomics Database (CTD) to analyze the mechanistic pathways through which metal mixtures may induce schizophrenia. Relative mRNA expression levels were measured using Real-Time Quantitative Reverse Transcription Polymerase Chain Reaction (RT-qPCR). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were conducted to predict potential biological functions. In logistic regression models, compared to the lowest exposure group (Q1), the odds ratios (ORs) for Pb in groups Q2, Q3, and Q4 were 2.18 (95% CI: 1.20–3.94), 4.74 (95% CI: 2.52–8.95), and 3.62 (95% CI: 1.80–7.28), respectively. Both BKMR and gWQS models indicated a positive correlation between the combined effects of toxic heavy metal mixtures and the risk of schizophrenia, with Pb demonstrating the most substantial impact, particularly in older adults and females. Elevated levels of tumor necrosis factor (TNF) and interleukin-1 beta (IL-1β) were observed in patients with schizophrenia, while the expression of tumor protein p53 (TP53) was significantly reduced. These findings underscore the critical need to avoid exposure to toxic heavy metals to prevent schizophrenia, highlighting significant public health implications.

Pregnancy-Related Mortality Disparities During the COVID-19 Pandemic.

Objectives. To compare pregnancy-related mortality ratios (PRMRs) associated with COVID-19 by race/ethnicity, by region of residence, and in states with and without Medicaid expansion. Methods. We used 2020-2021 data from the US Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research in our analysis. We stratified PRMRs by race/ethnicity, census regions, and Medicaid expansion and nonexpansion states. Results. The 2020-2021 PRMR was 40.3 per 100 000 live births. American Indian/ Alaska Native pregnant people had the greatest PRMR, followed by non-Hispanic Blacks and non-Hispanic Native Hawaiians/other Pacific Islanders. PRMRs associated with COVID-19 in the southern region were at least 2 times higher than in other regions and were highest for all pregnant people in the various racial/ethnic groups. PRMRs associated with COVID-19 were lower in Medicaid expansion states than in nonexpansion states. Conclusions. The US COVID-19 epidemic exacerbated racial and ethnic disparities in pregnancy-related mortality. Public Health Implications. The alarming increase in disparities among racial and ethnic pregnant people during the COVID-19 pandemic underscores the need to address social determinants of health at the structural level.

Hepatitis A, B, and C in Brazilian Afro-Descendant Communities from Northeast Brazil: A Seroepidemiological Survey.

Viral hepatitis is a disease that is more prevalent among individuals residing in remote regions and in contexts of social vulnerability. The objective of this study was to ascertain the seroprevalence of hepatitis A (HAV), B (HBV), and C (HCV) in vulnerable communities in the rural area of São João do Piauí (SJP), northern Brazil. Immunoenzymatic assays were employed to detect the presence of anti-HAV (total and IgM), HBsAg, anti-HBc, anti-HBs, and anti-HCV serological markers in serum samples. Samples that yielded positive results were subjected to further analysis using real-time polymerase chain reaction (PCR). A total of 492 individuals, ranging in age from 3 to 101 years, were consecutively recruited from eight rural communities. The majority of individuals were female (51.2%), over 30 years of age (57.1%), self-identified as Black/Brown (92.2%), and resided in Afro-Brazilian communities, designated as "quilombos" (68.1%). The seroprevalence of anti-HAV was 69.5% (95% CI: 65.4-73.6%), while that of anti-HBc was 4.7% (95% CI: 2.8-6.6%), and that of anti-HBs was 35.2% (95% CI: 30.1-39.4%), and 0.2% (95% CI:0.0-0.6%) for anti-HCV. The seroprevalence rates observed were higher than the national average, and a significant proportion of individuals in the target age groups were susceptible to HBV, despite the availability of vaccination. These findings highlight potential shortcomings in the management of vaccine-preventable diseases, which could have implications for public health.

Exploring metabolic syndrome and dietary quality in Iranian adults: a cross-sectional study

BackgroundMetabolic syndrome (MetS) is a cluster of cardiovascular risk factors affecting a quarter of the global population, with diet playing a significant role in its progression. The aim of this study is to compare the effectiveness of the Dietary Diabetes Risk Reduction Score (DDRRS) and the Macronutrient Quality Index (MQI) scoring systems in assessing the diet-related risk of metabolic syndrome.MethodsIn this cross-sectional study, data from 7431 individuals aged between 30 and 70 years, obtained from the Mashhad Cohort Study, were utilized to evaluate the risk factors of metabolic syndrome. A valid semi-quantitative food frequency questionnaire was used to assess participants’ dietary intake. The MQI was calculated based on carbohydrate, fat, and healthy protein components, while the DDRRS was also computed. Anthropometric measurements and blood samples were taken to determine the presence of metabolic syndrome. Logistic regression analyses were conducted to assess the association between MQI and DDRRS with metabolic syndrome and its components.ResultsAccording to the crude model, we observed lower odds of MetS in the highest quartile of DDRRS and MQI compared to the lowest quartile (P-trend < 0.001). This trend persisted in the fully adjusted models, revealing odds ratios of 0.399 (95% CI: 0.319-0.500) and 0.597 (95% CI: 0.476–0.749) for DDRRS and MQI, respectively. After controlling for all potential confounders, we observed lower odds of central obesity in the highest quartile of MQI (OR: 0.818, 95% CI: 0.676–0.989, P-trend = 0.027). Furthermore, we found that the odds of high triglyceride levels were lower in the highest quartile of DDRRS compared to the lowest quartile (OR: 0.633, 95% CI: 0.521, 0.770, P-trend < 0.001).ConclusionIn conclusion, our study indicates that greater adherence to both DDRRS and MQI is linked to a decreased risk of metabolic syndrome and its components. These findings hold significant implications for public health and the development of personalized nutrition strategies.

Vaping Possible Negative Effects on Lungs: State-of-the-Art From Lung Capacity Alteration to Cancer.

Vaping has emerged as a popular alternative to traditional smoking. It produces smokeless vapour by heating an e-liquid mixture in an atomizer. This paper delves into the current state of knowledge surrounding electronic cigarettes, exploring the gap between the perceived safety of e-liquids and the emerging evidence of their harmful effects when inhaled. As we navigate this intricate landscape, it is crucial to unravel the complexities of vaping and its implications for public health. We conducted a three-layer systematic review of the guidelines set by the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Meta-analyses of Observational Studies in Epidemiology (MOOSE). The search was performed in three layers, including the first layer, the effect of vaping on lung function; the second layer, the effect of vaping on lung structure and inducing lung injury; and the third layer, the physiopathologic effect of vaping on the lung and a possible carcinogenic effect. Exposure to e-cigarette vapour reduced lung ventilation in adult male Long-Evans rats, indicating impaired lung function. In male Wistar rats, vaping was associated with a decrease in lung air volume and denser lung tissue structure. Studies on guinea pigs showed that vaping caused acute bronchoconstriction, contributing to lung function impairment. A case study of a young man with an E-cigarette and vaping-induced lung injury (EVALI) highlighted the detrimental effects of vaping on human lung function. The EVALI outbreak in the USA was linked to harmful substances in vapes, such as vitamin E acetate and THC, leading to serious lung injuries, including pneumonia and bronchiolitis. Vaping poses significant health risks, especially to young adults, and misconceptions regarding its safety persist despite evidence of its potential to cause various lung diseases. While vaping has positioned itself as a smoking cessation aid, the discussion surrounding its impact on lung health requires careful consideration. The lack of conclusive evidence on the long-term effects of vaping underscores the need for further research. However, existing data suggest that vaping is not without risks, and its potential association with respiratory issues and cancer underscores the urgency of public health interventions.

Quantifying the noncarcinogenic and carcinogenic risks resulting from the inhalation of PM2.5-bound metals: A multicity analysis and implications for public health

Toxic metals in PM2.5 represent a growing public health concern because of their potential health effects. Ambient PM2.5 samples were collected from five provinces around Bangkok from December 2020 to December 2021. The concentrations of PM2.5 and metals (arsenic, cadmium, chromium, cobalt, nickel, lead, and vanadium) were analyzed. The noncarcinogenic and carcinogenic risks were evaluated via Monte Carlo simulations in four age groups (0 to <6, 6 to <12, 12 to <18, 18–70 years), with a dataset comprising 2282 heavy metal assays within the particulate matter. Significantly higher PM2.5 concentrations were detected in provinces with higher factory densities, as well as higher concentrations during haze periods than during non-haze periods. The HI values for all age groups and provinces were lower than 1, indicating acceptable noncarcinogenic risks. The carcinogenic risks from PM2.5-bound metals varied between 7.08×10−7 and 4.29×10−6, indicating increased cancer risks, for preschool children and adults. Cancer risk was highest in industrial areas, followed by areas with dense traffic, and lowest in agricultural areas. The results indicated that Thailand's current air quality regulations, which primarily provide only lead limits, are insufficient considering the high carcinogenic potential of other metals. The Monte Carlo simulation results confirmed that lowering Thailand’s 24-h PM2.5 standard from 37.5 to either 25 or 15 µg m−3, as specified in the 2021 World Health Organization guidelines, would decrease cancer risk by 9.63–43.18 %.

Harnessing the Link between Climate Change and Traditional Food Preservation Methods: Implications for Global Food Security and Public Health

Climate change is a global issue, which impacts the different geographical zones in different levels. It is also linked to numerous human health issues, which are a concern to human health. The impact of climate change on traditional methods of food preservation in Nigeria and the consequences for food security and health are examined in this research. Information from the Nigerian Meteorological Agency (NIMET) and the National Emergency Management Agency (NEMA) show that average temperatures are increasing and rainfall is decreasing, which are effects of climate change that affect agriculture, water resources, and traditional food preservation methods that are detrimental to public health.Traditional food preservation methods are critical for understanding the link between climate change and food security.This paper uses a case study of Nigeria to examine the effects of climate change on traditional food preservation practices and public health. The research focuses on the shifts in the conventional preservation techniques, the impact of these shifts on nutrition, and policy interventions for enhancing sustainable preservation of food. Climate change indicators such as temperature and rainfall were used as surrogates for climate change, food insecurity such as undernourishment rates were used for food security and nutritional health outcomes such as child stunting and micronutrient malnutrition. The study shows that climate change has a negative effect on food security since it reduces crop yields and enhances post-harvest losses. Sun-drying and smoking are the common preservation techniques that are now less efficient because of high humidity and unpredictable weather. As such, people are experiencing increased incidences of food wastage, nutritional imbalance, and food borne diseases especially with those people in rural regions. Furthermore, the study confirms the relationship between climate change and food insecurity, which has a negative impact on the health of pregnant women and children, especially under five years, and high under-five mortality despite a decrease in child mortality in the last decade.The results provide important regional information relevant to the entire Sub-Saharan Africa and useful to the international community in matters of climate change, food security and health. This study calls for the use of innovation that combines the conventional and contemporary methods of food preservation in order to mitigate the impacts of climate change on food security systems. Furthermore, it underlines the need for the policy interventions that may prevent food borne illness and other diseases. These insights are in line with the United Nations Sustainable Development Goals (UN-SDGs) 2, 3, and 13, namely; Zero Hunger, Good Health and Well-being, and Climate Action, respectively.This research addresses a significant gap in the literature by linking climate change effects with food preservation practices and offering recommendations for improving food system vulnerability to climate change. It provides a clear picture of the prospects and constraints of mitigating climate change impacts on food insecurity and enhancing food security and health in the world.

A Comprehensive Multi-Omics Study of Serum Alterations in Red Deer Infected by the Liver Fluke Fascioloides magna.

Liver fluke infections are acknowledged as diseases with global prevalence and significant implications for both veterinary and public health. The large American liver fluke, Fascioloides magna, is a significant non-native parasite introduced to Europe, threatening the survival of local wildlife populations. The aim of this study was to analyze differences in the serum proteome and metabolome between F. magna-infected and control red deer. Serum samples from red deer were collected immediately following regular hunting operations, including 10 samples with confirmed F. magna infection and 10 samples from healthy red deer. A proteomics analysis of the serum samples was performed using a tandem mass tag (TMT)-based quantitative approach, and a metabolomics analysis of the serum was performed using an untargeted mass spectrometry-based metabolomics approach. A knowledge-driven approach was applied to integrate omics data. Our findings demonstrated that infection with liver fluke was associated with changes in amino acid metabolism, energy metabolism, lipid metabolism, inflammatory host response, and related biochemical pathways. This study offers a comprehensive overview of the serum proteome and metabolome in response to F. magna infection in red deer, unveiling new potential targets for future research. The identification of proteins, metabolites, and related biological pathways enhances our understanding of host-parasite interactions and may improve current tools for more effective liver fluke control.

Exploring the short-term effects of extreme temperatures on tuberculosis incidence in Shantou, China: a Coastal City perspective.

Coastal cities, due to their proximity to coastlines and unique climatic conditions, face growing challenges from extreme temperature events associated with climate change. Research on the impact of extreme temperatures on tuberculosis (TB) in these cities is limited, and findings from different regions lack consensus. This study focuses on Shantou, a coastal city in China, to investigate the influence of extreme temperatures on TB within this distinctive geographical context. Distributed Lag Non-Linear Models (DLNM) were employed to evaluate the effect of extreme temperatures on TB incidence risk in Shantou, a coastal city in China, spanning from 2014 to 2021. Daily TB case data were provided by the Shantou Tuberculosis Prevention and Control Institute. Daily meteorological information was sourced from the Reliable Prognosis website, while daily air pollutant data were obtained from the China Air Quality Online Monitoring and Analysis Platform. The study revealed a significant association between extreme temperatures and TB incidence, with the impact peaking at a lag of 27 days after exposure. Notably, extreme cold temperatures led to a temporary decrease in TB incidence with a lag of 1-2 days. Subgroup analysis indicated that males had a notably higher risk of TB under extreme temperature conditions compared to females. Additionally, individuals aged 65 years and above showed a significant cumulative effect in such conditions. This research enhances our comprehension of the effects of extreme temperatures on TB in coastal cities and carries substantial public health implications for TB prevention in China.

Relationship between socioeconomic status and stroke: An observational and network Mendelian randomization study

BackgroundThe relationship between socioeconomic status (SES) and stroke remains controversial, and the underlying mediator is unclear. This study aimed to assess the causal relationship of SES with stroke and its subtypes and to identify potential modifiable risk factors responsible for this relationship. MethodsThe study included 372,437 participants from the UK Biobank. Over an average period of 12.13 years, 6,457 individuals (2.7 %) were recorded as having experienced a stroke. Cox proportional hazards model was used to determine the relationship between SES (average annual household income before tax and age at the end of full-time education) and stroke, ischemic stroke, and hemorrhagic stroke. Two-sample Mendelian randomization (MR) was employed to assess the causal relationship between SES and stroke and its subtypes. Furthermore, network MR was utilized to evaluate the potential mediating role of modifiable risk factors for stroke in this causal relationship. ResultsAfter adjusting for factors such as sociodemographic characteristics, health behaviors, health status, and past medical history, participants in the second highest income group showed the lowest risk of stroke, with a hazard ratio (HR) of 0.780 (95 % confidence interval [CI]: 0.702–0.866), and for ischemic stroke, the HR was 0.701 (95 % CI: 0.618–0.795). Those who completed full-time education at the latest age group(>18 years) had the lowest risk of stroke (HR: 0.906, 95 % CI: 0.830–0.988) and ischemic stroke (HR: 0.897, 95% CI: 0.811–0.992). MR analysis showed that higher income and education were both associated with a lower risk of stroke (income: inverse-variance-weighted odds ratio [ORIVW] =0.796, 95 % CI: 0.675–0.940, education: ORIVW = 0.631, 95 % CI: 0.557–0.716) and ischemic stroke (income: ORIVW = 0.813, 95 % CI: 0.684–0.966, education: ORIVW = 0.641, 95 % CI: 0.559–0.735). Additionally, hypertension had the highest mediating effect on this relationship. It accounted for 57.12 % of the effect of income on stroke, 51.24 % on ischemic stroke, and 27 % and 24 % for education. ConclusionHigher SES was associated with a lower risk of stroke and ischemic stroke, and hypertension had the highest mediating effect on this causal relationship. The results have significant public health implications, emphasizing the importance of early intervention to reduce the risk of stroke in low SES populations.

Dietary Habits of Young Poles and Their Selected Determinants: A Review and Implications for Public Health.

This study investigates the dietary patterns, health behaviors, and related determinants among young people in Poland, amid increasing lifestyle-related health concerns like obesity and poor nutrition. Understanding the factors influencing these behaviors is crucial for crafting effective public health strategies. The objective was to analyze young Poles' eating habits, their perceptions of health, and the role of various determinants in shaping these behaviors. A survey was conducted among a representative sample of young Poles, gathering data on eating habits, health perceptions, and lifestyle choices. The survey focused on the respondents' understanding of healthy eating, sources of nutrition knowledge, and the influence of family, social media, and public health campaigns. Data were analyzed using descriptive statistics, and correlations between health behaviors and socio-demographic factors were examined. The study revealed that 88% of young respondents prioritize health, with 73% acknowledging a link between nutrition and health. While most participants accurately described healthy eating and reported adherence to dietary guidelines, 43% engaged in emotional eating, which often led to compulsive behaviors associated with obesity. Social media, internet articles, and family were primary sources of nutrition knowledge. Despite their knowledge, fruit and vegetable consumption was below recommended levels, and physical activity levels were insufficient in nearly half of the respondents. Only 36% regularly read food labels, with many choosing products containing additives. Appearance-related stress was prevalent among 52% of respondents, while sleep deficits and lack of sufficient physical activity were common. The findings suggest that while young Poles possess a high level of awareness regarding healthy eating, gaps remain in the application of this knowledge, particularly concerning emotional eating and inadequate fruit and vegetable consumption. Public health campaigns should be more effectively targeted to address these gaps and promote sustainable health behaviors from early childhood. Addressing emotional eating, enhancing physical activity, and improving nutrition education through effective channels like social media are key to improving public health outcomes.

Incidence of foodborne diseases in Ecuador.

Motivation for the study. In Ecuador, foodborne disease (FBD) incidence rates adjusted for population size have not been estimated, which will serve to identify priority geographic areas. Main findings. Between 2015-2020, 113,695 cases of FBD were identified, with "other food poisoning" and hepatitis A being most common. The highest incidence rates were found in the Amazon region. There is marked variability by geographic region in the incidence rates during the study period. Public health implications. It is necessary to optimize the registry system, establish detection and treatment protocols, analyze the causes related to the higher incidence of FBD in the Amazon region, and design a health promotion program focused on preventing contamination and establishing diagnostic and treatment protocols. In order to describe the incidence rates per 100 000 population of foodborne disease (FBD) cases during the period 2015-2020 in Ecuador, we carried out a secondary analysis of epidemiological surveillance records and population projections from the National Institute of Statistics and Census. A total of 113,695 cases were reported with an incidence of more than 100 cases per 100 000 population (2015-2019). In 2020, the records are considerably lower than those reported in previous years. Most cases were reported as "other food poisoning". The highest incidence rates of FBD were found in the Amazon region. In general, there is a marked annual variability in the incidence of FBD according to the geographic regions of Ecuador. In conclusion, FBD represent a public health problem in Ecuador. Comprehensive preventive strategies should be designed with special emphasis on the Amazon region.
