The proliferation of digital public service platforms and the expansion of e-government initiatives have significantly increased the volume and diversity of citizen-generated feedback. This trend emphasizes the need for classification systems that are not only tailored to specific administrative domains but also robust to the linguistic, contextual, and structural variability inherent in user-submitted content. This study investigates the comparative effectiveness of large language models (LLMs) alongside instruction-tuned embedding models in the task of categorizing public transportation complaints. LLMs were tested using a few-shot inference, where classification is guided by a small set of in-context examples. Embedding models were assessed under three paradigms: label-only zero-shot classification, instruction-based classification, and supervised fine-tuning. Results indicate that fine-tuned embeddings can achieve or exceed the accuracy of LLMs, reaching up to 90 percent, while offering significant reductions in inference latency and computational overhead. E5 embeddings showed consistent generalization across unseen categories and input shifts, whereas BGE-M3 demonstrated measurable gains when adapted to task-specific distributions. Instruction-based classification produced lower accuracy for both models, highlighting the limitations of prompt conditioning in isolation. These findings position multilingual embedding models as a viable alternative to LLMs for classification at scale in data-intensive public sector environments. Full article

Background/Objectives: Public transportation drivers are exposed to a variety of occupational hazards. The scope of this study is to describe the most significant changes in symptoms and work-related disorders in the last decade in a sample of professional drivers from a large Romanian city, and, in particular, the cardio-metabolic and musculoskeletal impact. Methods: A retrospective study on 186 professional tram, trolley, and bus drivers from a total number of 344 employed by the company was conducted. The initial values (pre-employment) of the BMI, blood pressure, cholesterol, fasting glycemia, and musculoskeletal complaints were compared to the values of the last employment check-up. Results: After an average follow-up period of 11 years, BMI increased from 27.69 (SD = 4.68) to 30.06 (SD = 5.2) (p < 0.0001), cholesterol from 201.7 (SD = 39.87) to 212.62 (SD = 42.51), (p = 0.04). The number of cases of high blood pressure (25 to 56, p < 0.0001) and musculoskeletal complaints increased from 3 initial cases to 26 cases of neck pain (p = 0.07), from 2 to 49 cases of dorsal pain (p = 0.02), and from 18 to 59 cases of lumbar pain (p < 0.0001). High blood pressure and low back pain were significantly correlated with tenure, independent of other factors. Conclusions: As tenure is important in the development of cardiovascular and musculoskeletal diseases, specific interventions should be developed in the early stages of the drivers’ career.

Over the past three turbulent decades, research has profoundly reshaped our understanding of chronic Toxoplasma gondii infection—traditionally regarded as harmless in immunocompetent individuals—unveiling its surprising impact on human health, performance, and behavior. This review emphasizes the effects of chronic Toxoplasma infection on physical and mental health, cognitive performance, and behavioral changes, highlighting key findings from studies investigating these domains, with a particular focus on both ultimate and proximate mechanisms underlying the observed effects. To this end, the primary focus will be on human studies; however, animal model studies will also be thoroughly considered when necessary and appropriate, to provide context and additional important information. Research demonstrates that chronic Toxoplasma infection may contribute to a broad spectrum of physical health issues. Ecological studies have revealed correlations between toxoplasmosis prevalence and increased morbidity and mortality from various conditions, including cardiovascular diseases, neurological disorders, and certain cancers. Large-scale cross-sectional studies have further shown that infected individuals report a higher incidence of numerous health complaints and diagnosed diseases, suggesting a significant impact on overall physical well-being. In addition to physical health, lifelong Toxoplasma infection (subclinical toxoplasmosis) has been implicated in cognitive impairments and behavioral changes. Studies have reported associations between infection and poorer performance in areas such as reaction time, processing speed, working memory, and executive function. Many of these behavioral changes likely relate to worsened health and a shift towards a “fast life history strategy.” These cognitive deficits can have significant implications for daily functioning and performance. Furthermore, the role of Toxoplasma infection in the development or exacerbation of mental health disorders has been extensively investigated. Meta-analyses, ecological studies, and large-scale observational studies have demonstrated associations between Toxoplasma infection and an increased risk of disorders such as schizophrenia and obsessive–compulsive disorder. While the precise mechanisms underlying these associations remain under investigation, research suggests that neuroinflammation and alterations in neurotransmitter systems are likely to play a role. Far from being harmless, subclinical toxoplasmosis is increasingly recognized as a hidden factor influencing human health, behavior, and cognitive performance—with implications that extend well beyond the individual to public health at large. Further research is warranted to elucidate the complex interplay between Toxoplasma infection, host physiology, and the development of various physical, cognitive, behavioral, and mental health conditions.

The digital transformation of public services has led to a surge in the volume and complexity of informatics-related complaints, often marked by ambiguous language, inconsistent terminology, and fragmented reporting. Conventional keyword-based approaches are inadequate for detecting semantically similar issues expressed in diverse ways. This study proposes an AI-powered framework that employs BERT-based sentence embeddings, semantic clustering, and classification algorithms, structured under the CRISP-DM methodology, to standardize and automate complaint analysis. Leveraging real-world interaction logs from a public sector agency, the system harmonizes heterogeneous complaint narratives, uncovers latent issue patterns, and enables early detection of technical and usability problems. The approach is deployed through a real-time dashboard, transforming complaint handling from a reactive to a proactive process. Experimental results show a 27% reduction in repeated complaint categories and a 32% increase in classification efficiency. The study also addresses ethical concerns, including data governance, bias mitigation, and model transparency. This work advances citizen-centric service delivery by demonstrating the scalable application of AI in public sector informatics. Full article

Background/Objectives: Breast implants are widely used in reconstructive surgeries, as well as in cosmetic procedures, to enhance or restore breast shape and volume. With advances in techniques and materials, these devices have become safer and more effective over the years. Nevertheless, complications such as capsular contracture, rupture, infections, or other types of malignancies (BIA-SCC). This study evaluated the postmarketing safety and performance of implants via technovigilance data and a review of scientific studies. Methods: The research analyzed publications from the BVS, PubMed, Embase, and ClinicalTrials databases from between 2007 and 2023 (15 years), in addition to reports registered in the Notivisa system during the same period. Results: A total of 113 studies were identified, 15 of which were selected for the final analysis, which revealed that capsular contracture, seroma, infection, and rupture were the most common complications. In the Notivisa system, 786 reports were found, including 397 technical complaints and 389 adverse events, with pain, infections, and lymphoma among the most frequently reported issues. Conclusions: These findings highlight the importance of continuous surveillance to identify risks and promote improvements in the quality and safety of breast implants, ensuring patient well-being. As a practical contribution, a clinical decision-making algorithm was proposed to support healthcare professionals in the early identification and management of implant-related complications.

Background/Objectives: Developmental Topographical Disorientation (DTD) refers to a condition in which individuals report getting lost in very familiar surroundings, since childhood, with no other cognitive complaints, and no brain injuries or neurological disorders. While the cognitive and neurological mechanisms underlying DTD are being investigated, to date, there is no tool available to the public and health practitioners for identifying this lifelong condition. Methods: Here, we used a decade of data (N = 3794) collected in healthy and DTD individuals to produce a short and reliable measure of self-reported sense of direction that could point to the presence of DTD. Results: We adopted a measure of internal consistency (Cronbach’s alpha) and identified four items of the well-known Santa Barbara Sense of Direction (SBSOD) Scale that retain its original strong internal consistency. These four items remain sensitive to the well-known effects of sex on spatial orientation and, importantly, to the presence of DTD, while maintaining the same pattern of association with a cognitive battery of computerized tasks measuring different spatial abilities. Conclusions: This four-item measure could be of practical use to obtain a rapid assessment of an individual’s self-reported sense of direction and help to identify the presence of DTD in the general population.

Background: Current evidence suggests that joint complaints can represent an extra-intestinal manifestation in patients with Celiac Disease (CD) without any rheumatic comorbidity. However, the prevalence of joint complaints in the context of both CD and rheumatic disease is not known. The aim of this study was to estimate the prevalence of joint complaints in patients with CD. Methods: We searched Medline, Embase, Cochrane, and Web of Science databases for studies reporting joint complaints in patients with CD between 1 January 1990 and 26 November 2024. Search results were screened by two independent reviewers. The pooled prevalence of joint complaints was estimated in meta-analysis using a random effects model. We conducted stratified analyses by region, age (adults vs. children), and study sample size. The Joanna Briggs Institute Critical Appraisal Tool was used to evaluate the quality of included studies, and publication bias was assessed using a funnel plot and Egger’s test. The study protocol was pre-registered in the PROSPERO database and the results were reported according to the PRISMA guidelines. Results: A total of 7414 publications were rendered in the search. Of these, 226 were reviewed in full text and 27 were included in the meta-analysis. Among 6901 patients with CD without any concomitant rheumatic diagnosis, 530 had joint complaints, yielding a weighted pooled prevalence of 10.7% (95%CI: 6.9–15.1). In meta-regression analysis, no association between the prevalence of joint complaints and patients’ clinical characteristics or demographics was found. Conclusions: This meta-analysis indicates that joint complaints in patients with CD without any specific rheumatic comorbidity are not uncommon. Increased awareness of joint complaints in CD is important to improve the diagnosis and clinical care of these patients. Full article

Intimate partner violence (IPV) is the main cause of violence against women, especially in Mexico. However, the causes, consequences, and solutions related to IPV have not been well understood in this population. A total of five focus groups that included Mexican women who were victims of IPV were conducted to understand the causes, consequences, and solutions related to IPV, and a thematic analysis was performed. A total of 32 participants were included, with a median (range) age of 35 (24–70). The main causes mentioned by the participants were (a) cultural ones, among which Machismo, transgenerational violence, and cultural norms and gender roles were the main categories; (b) emotional causes, among which the lack of emotional abilities and emotional dependence were the main categories; and (c) educative causes, among which the lack of information about mental health, emotional abilities, IPV, and healthy relationships was reported. The main consequences mentioned were (a) psychological; (b) physical; (c) economic; (d) family-related, including impacts on children; and (e) legal, in relation to IPV complaints and children’s custody. Finally, the main solutions mentioned by the participants were (a) prevention through education, including educational programs to address mental health, IPV information, healthy relationships, and training in emotional skills; (b) cultural transformation; and (c) institutional strengthening, with this last solution including improving public policies, improving legal advice, and training for legal authorities. In conclusion, the causes, consequences, and solutions related to IPV were varied and included many instances; therefore, its prevention and solution should be performed at the inter-institutional and community levels, in which the promotion of emotional skills should play a fundamental role.

Donkeys were traditionally used as draft animals for transporting cargo, as a means of transportation, and for riding purposes before the advent of mechanization. Following this historical shift, their economic significance declined, making them targets for other industries, such as Chinese industries that use donkey skin to extract gelatin (ejiao). Since donkey slaughter is not a regulated activity in Brazil, the welfare and survival of donkeys are increasingly at risk as demand for their skins rises. Complaints filed by public agencies in Brazil have raised concerns about the donkey slaughter chain in the country, questioning whether this production system operates under regulated standards or follows an extractive model. The objective of this study was to evaluate the production system of donkeys destined for slaughter in Brazil through physical and hematological assessments, aiming to identify potential systemic failures that may compromise animal welfare. To achieve this, physical and hematological evaluations were conducted on a group of 104 abandoned donkeys. The physical assessments aimed to determine the animals’ sex, estimate their age, and evaluate their body condition score (BCS). These were conducted through examination of the genital organs and dental arcades, with the neck evaluated using a scale from 0 to 4 and the body condition assessed using a scale from 1 to 9, respectively. Hematological assessments included the measurement of hematocrit (HT), total plasma protein (TPP), and plasma concentration of fibrinogen. Most of the donkeys were entire males (n = 50–48.08%), with a median age of 15.1 years. The body condition score was 2 or 3 (n = 36, 52%), and the neck condition score was 1 (n = 3, 37.5%). The majority of animals had hematocrit levels above 25%, total plasma protein levels below 7.5 g/dL, and fibrinogen levels exceeding 400 mg/dL. Based on the data analysis, the animals were characterized as being in poor health, since all groups exhibited altered body and neck condition score, plasma fibrinogen concentration, and total plasma protein. These parameters may be indicative of malnutrition and systemic inflammation, even though other laboratory results showed no signs of disease. Activities characterized by mistreatment contribute to an unsustainable extractive model. Full article

Objectives: To evaluate the patient-reported impact of retinitis pigmentosa (RP) in a large patient cohort to identify relevant disease-related disadvantages as key aspects for the improvement of ophthalmic and social care. Methods: Consecutive patients with molecularly confirmed RP older than 18 years of age were identified in two tertiary care centers in Germany. Patients were contacted to participate in an anonymized patient query regarding the impact of RP on their vocational training, professional career, and social, familial, and personal life, as well as their experience with ophthalmologic care. Results: Out of 241 contacted patients, 162 responded (67.2%; 52.5% female, 67.3% younger than 50 years of age). While the impact of RP on vocational training was limited, professional careers were frequently disrupted with early retirement rates of 39.8% (≥40 years of age) to 50% (≥50 years of age). Most respondents felt restricted in their participation in public life (66.3%). One-fifth complained about financial restrictions; however, one-third of this number did not obtain financial help. A negative impact on familial life (21.4%) was less frequently reported compared to personal impairments, especially anxiety (74.5%) and depression (24.2%). Most respondents considered their ophthalmic care as adequate; however, a delayed diagnosis (≥two years: 28.6%) and initial misdiagnosis (24.0%) were frequent. Insufficient psychological support was the major complaint about professional care. Conclusions: RP affects the lives of patients in multiple aspects. Ophthalmic and social care providers should focus on the acceleration of the diagnostic process, as well as easy access to financial assistance and psychological support, as key areas for improvement. Improvements in these areas are expected to reduce challenges for patients. They should have an impact on rehabilitation, participation in public life, and quality of life. Full article

The Chilean feminist movements challenged the state and educational authorities regarding recurring instances of gender-based violence that were perpetuated and silenced. Reports of harassment and sexual abuse led to a broader critique about the ways in which education plays a part in the establishment of a model that sustains gender gaps. University authorities responded with institutional policies, establishing protocols and formal spaces to address these issues. However, these measures have revealed new problems. Given that the institutional response to the feminist uprising illuminated a range of nuances, obstacles, and new tensions related to issues of punishment, reparation, and justice, we identify four critical points of these political dissonances that emerged in Chilean universities following this cycle of protests: 1. problems in the definition and naming of violence and experiences of grievance; 2. public exposure of grievances, including “funas” (public shaming) and punitive practices; 3. disputes over the meaning of the slogan “non-sexist education”; 4. challenges in integrating the feminist complaint within the university community. Based on the analysis of slogans, key protest moments, and a comprehensive literature review, we argue that these tensions may hinder feminism’s transformative potential while simultaneously enabling a valuable internal critique.

Airline customers will often complain to the relevant authorities if they encounter an unpleasant flight experience. The specific complaint information can directly reflect the various service problems encountered, so conducting in-depth research on public air transport passenger complaints can reveal important details for improving service. Therefore, by analyzing the passenger complaint data of relevant civil aviation departments in China, we propose a method for identifying key topics of passenger complaints based on text mining. We organically integrate sentiment analysis, topic modeling and association rule mining. A new complaint text analysis framework is constructed, which provides new perspectives and ideas for complaint text analysis and related application fields. First, we calculate the sentiment orientation of the complaint text based on the sentiment dictionary method and filter complaint texts with strong negative sentiment. Then, we compare the two topic modeling methods of LDA (Latent Dirichlet Allocation) and LSA (Latent Semantic Analysis). Finally, we select the better LDA method to extract the main topics hidden in the passenger complaint text with high negative emotional intensity. We use the Apriori algorithm to mine the association rules between the complaint topic words and the service problem classification labels on the complaint text. We use the FP-growth algorithm to mine the association rules between the complaint subject words and the service problem classification labels on the complaint text. By comparing the Apriori algorithm with the FP-growth algorithm, the results of mining the support, confidence and promotion of the association rules show that the Apriori algorithm is more efficient. Finally, we analyze the causes of specific service problems and suggest improvement strategies for airlines and airports. Full article

Background: Farmers are continuously exposed to pesticides during crop production, which can lead to both acute and chronic poisoning. This exposure poses a significant global public health concern. In response, this study aims to achieve two primary objectives: (1) to identify the correlation between pesticide intoxication cases among farmers and their potential causes and (2) to assess the relationship between risk–control measures, hygiene practices, and resulting health effects. Methods: This study employed a cross-sectional mixed-methods observational design, sampling 112 farmers from Bogotá’s rural areas. Data were analyzed using logistic regression in R (version 4.2.1), examining eight associated variables. Results: The use of personal protective equipment (PPE) ranged from approximately 62% to 92%. Additionally, 82% of participants reported changing their workwear and 76% practiced bodily hygiene after exposure. Nevertheless, health complaints persisted—particularly affecting vision (46%), the respiratory system (38%), and the skin (32%). Notably, two out of every three farmers reported experiencing some form of systemic illness associated with pesticide exposure. Conclusion: A strong association was observed between the use of facemasks and changing workwear and the prevention of pesticide-related intoxication. These practices appear to be key in reducing chemical exposure during fumigation activities. Full article

Railways are considered an environmentally sustainable mode of transportation but can pose significant environmental challenges due to their operation and associated activities. Among these, noise generation is a persistent source of public complaints. In Korea, a maximum distance of 100 m from buildings has been proposed for new railway developments in residential areas, although this guideline lacks a solid foundation based on experimental evidence. Noise barriers are often installed as a mitigation measure; however, there is no standardized guideline for their height in relation to their effectiveness at varying distances. The distances and altitudes set in this study took into account accessibility and the height of noise barriers on actual railway sites. In particular, we examined the effects of altitude above and distance from a railway site under the assumption that the prefrontal cortex would be physiologically affected by noise exposure. In this study, we conducted the first analysis in Korea of cerebral blood flow changes in response to noise, to assess quantitatively the stress effects caused by railway environmental noise at varying distances from, and altitudes above, a railway. Using functional near-infrared spectroscopy (fNIRS), we measured prefrontal cortex activation in 10 adult males (average age: 33.2 years). Brain activation was evaluated under different distances from (40 and 100 m) and altitudes above (1st and 4th floors of a building) a railway through a paired-sample t-test analysis. Discomfort was felt at relatively close distances to the railway, and there were no differences in perceived discomfort between the examined floors. Brain activation due to environmental noise was highest in channel 43 (left DLPFC) for altitude (floor) and in channel 37 (left FPC) for distance. Significant differences in activation were observed in the corresponding Brodmann areas, varying based on altitude and distance (p < 0.05). These results provide valuable scientific data for the preliminary design phase of new railway developments, particularly with regard to determining appropriate residential distance and noise barrier specifications, to enhance comfort of nearby residents. Furthermore, they may contribute to the improvement of quality of life by reducing stress caused by railway environmental noise. Full article

Work-related musculoskeletal disorders (WMSDs) are a significant public health concern, particularly in professions requiring prolonged static postures. Objectives: This study examined the influence of demographic and occupational factors on the WMSD prevalence and provides evidence-based recommendations for workplace health improvements. Methods: A cross-sectional study (July–September 2024) surveyed 80 office employees in Varna, Bulgaria, using the Prevent 4 Work (P4Wq) questionnaire. ANOVA and t-tests assessed the WMSD prevalence across demographics, while Pearson’s correlations examined associations with age, BMI, and work experience. Data were analyzed in Jamovi v.2.6 (p < 0.05). Results: The sample (92.5% women, mean age 47.2 years) reported a high WMSD prevalence, with cervical pain (88.8%), lower back pain (83.8%), and shoulder pain (75.0%) being the most common. Work experience, age, and BMI were significantly correlated with WMSD severity, while gender showed no significant associations. Conclusions: WMSDs are highly prevalent among office employees, with lower back, neck, and shoulder pain being the most common complaints. Factors such as higher BMI, longer work experience, and increased workload are associated with greater symptom severity. These results emphasize the urgent need for targeted workplace interventions aimed at reducing ergonomic risks, improving posture, and enhancing employee well-being, ultimately fostering a healthier and more productive work environment.
