Background: Bullying is a significant problem worldwide and in Lithuania, especially among children and adolescents. This study aimed to assess the associations of bullying with adolescents’ subjective sense of happiness and general health. Methods: A cross-sectional study was conducted using an anonymous written questionnaire. Adolescents at various schools across Lithuanian cities and districts were surveyed to investigate the frequency of bullying among them over the past six months and its impact on their subjective sense of happiness and well-being. Results: This study included 4124 students from seventh to tenth grade; their average age was 14.48 ± 1.15 years, with 49.35% being boys. Over the past six months, the highest bullying incidence occurred at school, accounting for 25.79% of the cases. Only half of the respondents (48.81%) felt happy, and a little more than half felt healthy (63.11%). It was found that bullying at school (ρ_s = −0.224; ρ_s = −0.197), outside school (ρ_s = −0.207; ρ_s = −0.180), and online (ρ_s = −0.175; ρ_s = −0.110) is associated with adolescents’ sense of happiness and health. Conclusion: Bullying is common among Lithuanian adolescents and has a negative impact on their subjective happiness and well-being. It is crucial to develop prevention initiatives to decrease bullying in schools and within the community. Full article

Background/Objectives: For kidney transplantation, it is very important to provide effective post-transplantation interventions to help patients achieve continuous and efficient self-management. Therefore, we review the self-management interventions applied to kidney transplant recipients and suggest the optimal approach to increase the effectiveness of future self-management interventions. Design: Systematic review. Methods: Search terms and strategies included kidney transplantation; self-management; intervention; systematic review. We searched MEDLINE via PubMed, Excerpta Media dataBASE, Cochrane Register Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, and one domestic Korean database to identify studies of self-management interventions for kidney transplant recipients aged ≥ 18 years published in English or Korean until 14 May 2025. Two reviewers independently selected related studies and extracted relevant data. Identified studies were assessed for quality and bias. Results: Of 1340 studies identified, 27 with 1912 participants met the inclusion criteria. Educational interventions were the most common self-management interventions and were provided 3 months to 1 year after kidney transplantation; most interventions were administered by nurses. Outcome variables were divided into cognitive, behavioral, affective, and health outcomes. Educational interventions were effective in improving cognitive, behavioral, and affective aspects. Some differences were observed, depending on the study. Conclusions: We recommend that nurse-involved educational interventions be included when developing self-management interventions and guidelines for kidney transplant recipients in clinical and community nursing settings.

(1) Background: People living with spinal cord injury (SCI) face numerous challenges in their lives in terms of health conditions, everyday activity, and participation in society, which are not fully recognized. To address such issues, a community survey with 125 questions for people living with SCI was conducted and the response rates, population characteristics, health and functioning problems are reported. (2) Methods: The survey questionnaire comprised 125 questions on SCI characteristics, health conditions, activities, participation, and environmental and personal factors. The survey response rates were calculated, and demographics and health and functioning characteristics were analyzed. (3) Results: A total of 890 individuals responded to the survey. The median age of the participants was 48 years (interquartile range (IQR), 39–56), and 76% of the population were males. Paraplegia (60%) and complete injury (58%) were the most common injury type, and the cause was mostly traumatic (92%). More health problems and lower quality of life were more frequent with older age and in patients without paid work. (4) Conclusions: The Ko-InSCI study provides valuable information in terms of health needs and service gaps for people with SCI in the community. Full article

Heavy metal pollution represents a pervasive environmental challenge that significantly exacerbates the ever-increasing crisis of antimicrobial resistance and the capacity of microorganisms to endure and proliferate despite antibiotic interventions. This review examines the intricate relationship between heavy metals and AMR, with an emphasis on the underlying molecular mechanisms and ecological ramifications. Common environmental metals, including arsenic, mercury, cadmium, and lead, exert substantial selective pressures on microbial communities. These induce oxidative stress and DNA damage, potentially leading to mutations that enhance antibiotic resistance. Key microbial responses include the overexpression of efflux pumps that expel both metals and antibiotics, production of detoxifying enzymes, and formation of protective biofilms, all of which contribute to the emergence of multidrug-resistant strains. In the soil environment, particularly the rhizosphere, heavy metals disrupt plant–microbe interactions by inhibiting beneficial organisms, such as rhizobacteria, mycorrhizal fungi, and actinomycetes, thereby impairing nutrient cycling and plant health. Nonetheless, certain microbial consortia can tolerate and detoxify heavy metals through sequestration and biotransformation, rendering them valuable for bioremediation. Advances in biotechnology, including gene editing and the development of engineered metal-resistant microbes, offer promising solutions for mitigating the spread of metal-driven AMR and restoring ecological balance. By understanding the interplay between metal pollution and microbial resistance, we can more effectively devise strategies for environmental protection and public health. Full article

Extreme heat poses growing health risks in tropical regions, yet public perception of this threat remains understudied in the Caribbean. This study examines how residents in Puerto Rico perceived heat-related health risks and how these perceptions relate to vulnerability and protective behaviors during the extreme heat events of the summer of 2020. We conducted a cross-sectional telephone survey of 500 adults across metropolitan and non-metropolitan areas of Puerto Rico, using stratified probability sampling. The questionnaire assessed heat risk perception, sociodemographic characteristics, health status, prior heat exposure, and heat-related behaviors. While most participants expressed concern about climate change and high temperatures, fewer than half perceived heat as a high level of personal health risk. Higher levels of risk perception were significantly associated with being male, aged 50–64, unemployed, and in fair health, having multiple chronic conditions, and prior experience with heat-related symptoms. Those with symptoms were nearly five times more likely to report high levels of risk perception (OR = 4.94, 95% CI: 2.93–8.34). In contrast, older adults (65+), despite their higher level of vulnerability, reported lower levels of risk perception and fewer symptoms. Nighttime heat exposure was widespread and strongly associated with heat-related symptoms. Common coping strategies included the use of fans and air conditioning, though economic constraints and infrastructure instability limited access. The findings highlight the disparity between actual and perceived vulnerability, particularly among older adults. Public health strategies should focus on risk communication tailored to vulnerable groups and address barriers to heat adaptation. Strengthening heat resilience in Puerto Rico requires improved infrastructure, equitable access to cooling, and targeted outreach. Full article

Mast cell tumours (MCT) are the most common cutaneous neoplasms in dogs, with variable behaviours and patient survival time. Both indolent and aggressive forms have been described, but much remains to be explored regarding prognosis and therapy. Evidence has highlighted the influence of microbiota on multiple health and disease processes, including certain types of cancer in humans. However, knowledge remains scarce regarding microbiota biology and its interactions in both humans and canine cancer patients. This study aimed to characterise the faecal microbiota of dogs with MCT and compare it with that of healthy individuals. Twenty-eight dogs diagnosed with MCT and twenty-eight healthy dogs were enrolled in the study. Faecal samples were collected and analysed by Illumina sequencing of 16S rRNA genes. Alpha diversity was significantly lower in dogs with cancer, and the species diversity InvSimpson Indexwas reduced (p = 0.019). Principal coordinate analysis showed significant differences in the bacterial profile of the two groups: there was a significant lower abundance of the genera Alloprevotella, Holdemanella, Erysipelotrichaceae_UCG-003, and Anaerobiospirillum and, conversely, a significant increase in the genera Escherichia-Shigella and Clostridium sensu stricto 1 in diseased dogs. At the phylum level, Bacteroidota was significantly reduced in diseased dogs (25% in controls vs. 19% in MCT dogs). In conclusion, sequencing analysis provided an overview of the bacterial profile and showed statistical differences in the microbial communities of dogs with MCT compared with healthy dogs, suggesting a link between the gut microbiota and MCT in this species.

Plant microbiomes are vital for the growth and health of their host. Tree-associated microbiomes are shaped by multiple factors, of which the host is one of the key determinants. Whether different host genotypes affect the structure and diversity of the tissue-associated microbiome and how specific taxa enriched in different tree tissues are not yet well illustrated. Chinese fir (Cunninghamia lanceolata) is an important tree species for both economy and ecosystem in the subtropical regions of Asia. In this study, we investigated the tissue-specific fungal community structure and diversity of nine different Chinese fir genotypes (39 years) grown in the same field. With non-metric multidimensional scaling (NMDS) analysis, we revealed the divergence of the fungal community from rhizosphere soil (RS), fine roots (FRs), and thick roots (TRs). Through analysis with α-diversity metrics (Chao1, Shannon, Pielou, ACE, Good‘s coverage, PD-tree, Simpson, Sob), we confirmed the significant difference of the fungal community in RS, FR, and TR samples. Yet, the overall fungal community difference was not observed among nine genotypes for the same tissues (RS, FR, TR). The most abundant fungal genera were Russula in RS, Scytinostroma in FR, and Subulicystidium in TR. Functional prediction with FUNGuild analysis suggested that ectomycorrhizal fungi were commonly enriched in rhizosphere soil, while saprotroph–parasite and potentially pathogenic fungi were more abundant in root samples. Specifically, genotype N104 holds less ectomycorrhizal and pathogenic fungi in all tissues (RS, FR, TR) compared to other genotypes. Additionally, significant correlations of several endophytic fungal taxa (Scytinostroma, Neonothopanus, Lachnum) with the growth traits (tree height, diameter, stand volume) were observed. This addresses that the interaction between tree roots and the fungal community is a reflection of tree growth, supporting the “trade-off” hypothesis between growth and defense in forest trees. In summary, we revealed tissue-specific, as well as host genotype-specific and genotype-common characters of the structure and functions of their fungal communities. Full article

Staphylococcus aureus frequently causes intramammary infections in dairy cows (bovine mastitis), which impair animal welfare, milk yield, and food safety. This study determined the prevalence and genetic diversity of S. aureus in bulk tank milk (BTM) samples from community-based Alpine dairy pastures in Tyrol, a major milk-producing region in Austria. Throughout the 2023 Alpine season (May–September), 60.3% (94/156) of BTM samples tested positive for S. aureus at least once over the course of up to four samplings. A total of 140 isolates collected from the 94 S. aureus-positive community-based Alpine dairy pastures revealed 33 distinct spa types, with t2953 (n = 33), t529 (n = 12), t267 (n = 11), and t024 (n = 10) being the most common. Selected isolates representing the different spa types were characterised by DNA microarray-based genotyping, multi-locus sequence typing (MLST), and antimicrobial susceptibility testing. Isolates with spa types associated with bovine-adapted CC8 (CC8bov/GTB) were identified as the most common subtype, being detected in BTM samples from 35.3% (55/156) of the pastures. This emphasises the high prevalence of this subtype in dairy herds across European Alpine countries. Other common bovine-associated subtypes were also detected, including CC97, CC151, and CC479. While antimicrobial resistance was rare, enterotoxin-producing genes were detected in all CC8bov-associated spa types. Overall, these findings underscore the importance of rigorous hygiene practices in dairy farming, particularly in community-based Alpine dairy pastures, where the risk of transmission is particularly high. It also emphasises the need for continued surveillance and subtyping to improve animal health, ensure food safety, and promote sustainable milk production. Full article

Background and Objective: Large language model (LLM)–based chatbots are increasingly utilized by postpartum individuals seeking guidance on breastfeeding. However, the chatbots’ content quality, readability, and alignment with clinical guidelines remain uncertain. This study was conducted to evaluate and compare the quality, readability, and factual accuracy of responses generated by three publicly accessible AI chatbots—ChatGPT-4o Pro, Gemini 2.5 Pro, and Copilot Pro—when prompted with common maternal questions related to breast-milk supply. Methods: Twenty frequently asked breastfeeding-related questions were submitted to each chatbot in separate sessions. The responses were paraphrased to enable standardized scoring and were then evaluated using three validated tools: ensuring quality information for patients (EQIP), the simple measure of gobbledygook (SMOG), and the global quality scale (GQS). Factual accuracy was benchmarked against WHO, ACOG, CDC, and NICE guidelines using a three-point rubric. Additional user experience metrics included response time, character count, content density, and structural formatting. Statistical comparisons were performed using the Kruskal–Wallis and Wilcoxon rank-sum tests with Bonferroni correction. Results: ChatGPT-4o Pro achieved the highest overall performance across all primary outcomes: EQIP score (85.7 ± 2.4%), SMOG score (9.78 ± 0.22), and GQS rating (4.55 ± 0.50), followed by Gemini 2.5 Pro and Copilot Pro (p < 0.001 for all comparisons). ChatGPT-4o Pro also demonstrated the highest factual alignment with clinical guidelines (95%), while Copilot showed more frequent omissions or simplifications. Differences in response time and formatting quality were statistically significant, although not always clinically meaningful. Conclusions: ChatGPT-4o Pro outperforms other chatbots in delivering structured, readable, and guideline-concordant breastfeeding information. However, substantial variability persists across the platforms, and none should be considered a substitute for professional guidance. Importantly, the phenomenon of AI hallucinations—where chatbots may generate factually incorrect or fabricated information—remains a critical risk that must be addressed to ensure safe integration into maternal health communication. Future efforts should focus on improving the transparency, accuracy, and multilingual reliability of AI chatbots to ensure their safe integration into maternal health communications. Full article

Background: Anxiety and depression are among the most common mental health disorders affecting adolescents worldwide. Skipping breakfast is a prevalent dietary behaviour linked to inadequate nutrient intake, which may contribute to the development or exacerbation of mental health issues in this age group. Despite growing interest, a comprehensive synthesis of evidence on the association between breakfast omission and adolescent anxiety or depression remains limited. Objectives: This scoping review aimed to synthesise existing research on the association between skipping breakfast and the risk of anxiety and/or depression in adolescents. Methods: A systematic scoping review was conducted using the Joanna Briggs Institute (JBI) methodological framework. A comprehensive search of PubMed, ProQuest, and EBSCOhost databases was performed, focusing on studies published in English between 2014 and 2024. Keywords included “skipping breakfast,” “risk,” “anxiety,” “depression,” and “adolescen*.” Studies were screened and selected based on predefined inclusion and exclusion criteria. Results: Out of 1671 initially identified studies, 12 met the inclusion criteria. The majority were cross-sectional (n = 9), with one prospective cohort study, one secondary data analysis, and one systematic review with meta-analysis. Most studies reported a significant association between breakfast skipping and increased risk of anxiety and depression in adolescents. Only one study reported no significant relationship between the two variables. Conclusions: This review underscores a consistent association between skipping breakfast and elevated risk of anxiety and depression among adolescents. While causality remains to be established, breakfast omission emerges as a modifiable lifestyle factor with potential public health implications. These findings highlight the need for prospective research, as well as the importance of community- and school-based health promotion strategies that advocate for regular and nutritious breakfast consumption as part of broader mental health support efforts.

In the era of precision medicine, effective data visualisation plays a pivotal role in supporting clinical decision-making by translating complex, multidimensional datasets into intuitive and actionable insights. This paper explores the foundational principles of visual perception, with a specific focus on pre-attentive attributes such as colour, shape, size, orientation, and spatial position, which are processed automatically by the human visual system. Drawing from cognitive psychology and perceptual science, we demonstrate how these attributes can enhance the clarity and usability of medical visualisations, reducing cognitive load and improving interpretive speed in high-stakes clinical environments. Through detailed case studies and visual examples, particularly within the field of oncology, we highlight best practices and common pitfalls in the design of dashboards, nomograms, and interactive platforms. We further examine the integration of advanced tools—such as genomic heatmaps and temporal timelines—into multidisciplinary workflows to support personalised care. Our findings underscore that visually intelligent design is not merely an aesthetic concern but a critical factor in clinical safety, efficiency, and communication, advocating for user-centred and evidence-based approaches in the development of health data interfaces.

Background: Informal welders in Pretoria West face growing occupational safety risks due to hazardous working environments and limited regulatory oversight. Despite the high-risk nature of their work, many remain unaware of relevant safety legislation and inconsistently use personal protective equipment (PPE). This study aimed to investigate the occupational safety risks, challenges, and levels of compliance with safety practices among informal welders in Pretoria West, South Africa. Methods: A cross-sectional mixed-methods approach was employed, incorporating both qualitative and quantitative designs. Data were collected from 40 male welders (aged 20–55 years) using structured questionnaires, observational checklists, and semi-structured interviews. Descriptive statistics were generated using Microsoft Excel, while thematic content analysis was applied to the qualitative data. Results: Eighty-five percent (85%) of welders reported using gas welding, and more than half had received training in welding and PPE use; however, 47.5% had no formal training. A high prevalence of work-related injuries was reported, including burns, cuts, and eye damage. Common safety concerns identified were burns (42.5%), electric shocks (35%), and malfunctioning equipment. Observational data revealed inconsistent PPE use, particularly with flame-resistant overalls and eye protection. Qualitative insights highlighted challenges such as demanding client expectations, hazardous physical environments, and inadequate equipment maintenance. Many sites lacked compliance with occupational safety standards. Conclusion: The study reveals critical gaps in safety knowledge, training, and PPE compliance among informal welders. These deficiencies significantly elevate the risk of occupational injuries. Strengthening occupational health and safety regulations, improving access to PPE, and delivering targeted training interventions are essential to safeguard the well-being of welders and those in their surrounding communities.

Per- and polyfluoroalkyl substances (PFASs), commonly known as “forever chemicals”, are synthetic compounds with highly stable carbon–fluorine bonds, making them resistant to environmental degradation. These chemicals accumulate in ecosystems and water supplies, posing significant risks to human health, including cancer, immune system dysfunction, and neurological disorders. However, the mental health impacts of PFAS exposure remain underexplored, particularly in marginalized communities. This review examines the emerging evidence linking PFAS exposure to mental health issues such as anxiety, depression, and cognitive decline, with a focus on communities of color who face heightened vulnerability due to environmental and social health disparities. The review highlights the persistence of PFASs in the environment, common exposure pathways, and the disproportionate effects on populations living near contaminated sites. Despite some regulatory progress, U.S. regulations on PFASs are limited, especially compared to international standards. The review calls for stronger policy frameworks and emphasizes the need for environmental justice, health equity, and public awareness. By connecting environmental health, social justice, and mental well-being, the review aims to guide future research and policy reforms to mitigate the mental health consequences of PFAS exposure in vulnerable populations.

Toenail onychomycosis causes significant problems in public health and is more common among the elderly and immune-compromised populations. A previous culture-based survey of communal finely ground toenails from the east coast of Australia isolated 125 T. interdigitale but only one T. rubrum. This paucity of T. rubrum was surprising because it is one of the most common dermatophytes isolated worldwide. Our aim was to find out if T. rubrum was present but not cultured. DNA was extracted from ground toenails from the same samples. New specific primers were designed for the ITS region of T. rubrum that excluded T. interdigitale and vice versa. PCR with these new primers found T. rubrum as well as T. interdigitale in all ground toenail samples. This suggests that T. rubrum was present and common in the ground toenails. It was possibly missed by culture because it grows slowly and was overgrown by T. interdigitale and non-dermatophyte moulds. Alternatively, its viability may have declined earlier, during collection, treatment, or storage of the ground toenails. This has implications for studies of clinical materials, especially nails, as infection by T. rubrum (the most common dermatophyte) may be missed by culture, the main method used in pathology laboratories.

Introduction: Visual impairment impacts millions of people around the world, with the vast majority of problems being treatable. Disadvantaged communities are unable to utilize the same resources to treat these problems due to a lack of knowledge or resources, in addition to the presence of barriers preventing access. The objective of this paper is to assess eye health awareness and evaluate the barriers for individuals from disadvantaged communities in order to inform future interventions and increase access to care. Methods: This is a pilot study utilizing an online anonymous questionnaire designed to assess the demographics, eye health awareness, and access to eye care of community-based patients. A comprehensive literature review was also conducted using PubMed, Scopus, and Google Scholar to evaluate barriers to eye care and methods to improve community health outcomes. The primary goal was to improve understanding of eye health awareness and access in order to inform future strategies that can help in improving eye health awareness and service availability. Results: The results indicated that 61.2% of respondents believed that eye exams are very important, and only 7.7% of participants believed that regular eye exams are not important. The majority of participants (75%) agree that regular eye exams help prevent serious eye conditions and 84.5% believe that eye health can affect quality of life. 35.6% of participants reported they had their eyes checked by a healthcare professional within the last year, while 21.2% reported never having an eye exam. Although the majority of participants found access to eye care services in their community somewhat or very easy, 8.6% and 9.5% of participants found access difficult and very difficult, respectively. Even though 45.6% of participants reported not facing any barriers regarding access to eye care, the cost of services, long waiting times, and lack of nearby eye care providers were often cited as barriers from the remainder of the participants. Moving forward, local interventions such as mobile eye clinics, public health workshops, and telehealth are viable options to obtain an understanding of the community’s health status in addition to creating opportunities to educate and provide health screenings. Conclusion: The results indicate that although there is awareness of the importance of eye health for the majority of participants, there is still a sizable minority who have insufficient understanding. Barriers to healthcare such as cost, waiting times, and proximity to providers are common problems that are preventing many from seeking eye care. Future interventions should be created to increase access and literacy amongst the community through telehealth, mobile eye clinics, and public health workshops. Additional efforts should be taken by healthcare stakeholders to enhance care delivery, implement policies, and improve awareness. Full article
