Soldering is a common engineering practice that releases airborne particulate matter (PM), contributing to significant long-term respiratory risk. The health impact of this exposure is significant, with up to 22% of soldering workers worldwide being diagnosed with conditions such as occupational asthma, restrictive lung disease, and bronchial obstruction. Studies have reported that soldering can produce PM_2.5 concentrations up to 10 times higher than the U.S. Environmental Protection Agency’s (EPA) 24 h exposure limit of 35.0 μg/m³—posing significant respiratory and cognitive health risks under chronic exposure. These hazards remain underappreciated by novice engineers in academic and entry-level industrial environments, where safety practices are often informal or inconsistently applied. Air purification systems offer a mitigation approach; however, performance varies significantly with model and placement, and independent validation is limited. This study uses an indoor air quality monitoring system consisting of six AeroSpec sensors to measure PM_2.5–10 concentrations during soldering sessions conducted with and without commercial air purifiers. Tests were conducted with and without a selection of commercial air purifiers, and measurements were recorded under consistent spatial and temporal conditions. Datasets were analyzed to evaluate purifier effectiveness and the influence of placement on pollutant distribution. The findings provide independent validation of air purifier capabilities and offer evidence-based suggestions for minimizing particulate exposure and improving safety in laboratory soldering environments.

Fruit and vegetables (F&V) are recommended for a healthy life. Adolescence is a critical period for the onset of eating disorders and future health. F&V consumption among adolescents is globally low, making this group a key target for diet/nutrition-related interventions. This cross-sectional study aimed to assess F&V consumption among secondary school students in the food-insecure communes of Boukombe (rural) and Natitingou (urban), Benin. Using probabilistic random sampling, 303 students completed F&V intake frequency questionnaires and 24-h dietary recalls on school and non-school days. Poisson models identified factors associated with F&V consumption. The results showed that only 8.8% (Boukombe) and 11% (Natitingou) of students consumed fruit at least twice per day, and over 80% of students had not eaten fruit in the preceding 24 h; 9.9% and 11.4%, respectively, consumed vegetables at least twice per day. On average, 45.5% of students in Boukombe and 68% in Natitingou consumed at least three types of vegetables on school days. The most commonly consumed fruits were oranges in Boukombe and lemons in Natitingou. Factors influencing fruit consumption included sex (p = 0.005), age (p = 0.04), and mothers’ occupation (p = 0.03) on school days/and school or non-school days, while commune (p = 0.00017) and ethnic group affected vegetable consumption. Such low F&V consumption among surveyed students is a matter of public health concern, as it is likely to affect their health―in terms of micronutrient deficiency―and intellectual performance. These results should incentivize nutrition researchers, project managers, public health officials, and policymakers to (re)design and implement broader measures targeting secondary school students’ dietary practices to increase their F&V consumption.

Background/Objectives: This study aims to assess the ease of use, accuracy, consistency, reliability, and reproducibility in evaluating spine and pelvis conditions when transitioning from the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) Sixth Edition 2008 to the newly updated Sixth Edition 2024. Methods: Two rounds of impairment ratings were performed by a team consisting of three physician experts and four premedical students, focusing on a comparison between the 2008 and 2024 editions of the AMA Guides. The analysis included both the impairment values generated and the time taken to complete assessments with each version. Results: For the expert group, the mean duration required to complete an impairment rating was 5.0 min with the AMA Guides 2024, compared to 15.4 min using the AMA Guides 2008, with both editions achieving 100% accuracy and reliability. The premedical students demonstrated similar improvements, averaging 8.4 min per rating with the 2024 edition versus 26.4 min with the 2008 edition. The AMA Guides 2024 yielded enhanced accuracy, consistency, reliability, and reproducibility. Conclusions: The AMA Guides Sixth Edition 2024 represents a significant advancement in impairment evaluation, particularly for spine and pelvis assessments. This updated edition introduces a more streamlined and time-efficient process while preserving the accuracy, consistency, and reproducibility essential to high-quality impairment ratings. By enhancing clarity and standardization, it sets a new standard in occupational health, offering a reliable framework that supports both clinical assessment and administrative oversight.

In an air-conditioned multinational graduate students’ office in Japan during the winter season, we examined indoor environmental conditions, occupants’ perceptions, and their acceptance levels over five consecutive days. Indoor air quality (IAQ) acceptance peaked on the third day, coinciding with the most favourable thermal sensation vote, which was “neutral” at a geometric mean indoor temperature of 25.1 °C. Aural comfort received the lowest acceptance due to ongoing construction work, but did not significantly impact overall IEQ acceptance, thus suggesting that unacceptable aspects of indoor environmental quality (IEQ) can be offset by acceptable aspects. IAQ and thermal comfort compensated for its effects, offering insights into occupants’ environmental tolerance. IAQ sensation votes and visual comfort votes exhibit a strong relationship with overall comfort, as indicated by their respective R² values. However, variations in overall comfort are primarily explained by IAQ, which has the highest R² value of 0.50, suggesting that IAQ accounts for 50% of the changes in overall occupant comfort. Non-Japanese participants had lower IEQ acceptance and a significantly higher number of complaints than Japanese participants more so in visual comfort where acceptable luminance levels were higher in Japan than other participants’ countries of origin. Thermal comfort was mutually highly accepted by both groups. Nose and eye irritation were significantly experienced by the international participants due to low RH levels but experiencing loss of concentration and lethargy was comparable in both groups (p > 0.05, t-test). We recommend global coherence in indoor environmental quality standards as is the case with drinking water standards for public health protection and seamless transitions in new indoor environments.

The quality of education is significantly influenced by occupational health and safety (OHS) measures. To this end, a safety incident at a university could have far-reaching negative effects on facilitating teaching and learning for both lecturers and students. Although OHS standards are widely established in numerous industries, they are often overlooked in the academic setting. It is for this reason that, to date, research gap exists in OHS systems in academic settings. While universities primarily focus on education, they also pose significant health and safety risks to staff and students due to their design and setup. Effective implementation of an occupational health and safety management system (OHSMS) within universities can mitigate these risks. However, there is a notable lack of research focusing on the efficiency of OHSMS in South African universities. This study, therefore, aimed to fill this gap by assessing the efficiency of the OHSMS at a South African university. Data were collected using in-depth interviews, observations, and document analysis qualitative research methods. Data analysis was carried out using the thematic analysis approach. Inductive logic was used in the interpretation of the current study results. This study highlights that while there is strong awareness of the OHS Act 85 of 1993 (>90%) among university staff, significant gaps exist in the communication and enforcement (5%) of OHS policy, alongside the poor communication of hazards and risks (30%). Amongst other challenges are infrastructure maintenance (>35%), as well as the lack of standard operation procedures (>5%). To address some of these setbacks, the current study recommends enhancing policy communication, conducting regular hazard assessments, increasing training participation, and improving documentation practices. These steps aim to improve the efficiency and effectiveness of the university’s OHSMS, ensuring a safer environment for all stakeholders. Full article

Background: Burnout is a state of emotional, physical, and mental exhaustion produced by excessive and prolonged professional stress. Its prevalence is unclear, and figures from 2 to 81% have been reported, although studies focused on this issue are scarce and inconsistent definitions and the absence of validated measurement tools make comparisons difficult. Methods: Our narrative review’s purpose was to explore physician and medical student burnout across medical specialties and in specific subgroups, including young doctors, researchers, and female physicians. We also assess burnout effects in medical students and patients and the possible strategies to prevent and reverse it. Results: Burnout affects doctors, medical students, and patients. It impacts significantly on physicians mental health and can be the trigger for depression, substance abuse, and suicide attempts. Moreover, this psychological and physical exhaustion can also increase the risk of systemic conditions such as cardiovascular disease. Physician burnout increases the risk of medical errors, reduces professional efficacy, and might compromise patients’ safety. Strategies focusing on mental, physical, social, and occupational well-being can help to prevent and treat burnout. These include resilience training, self-care, exercise, work–life balance, and institutional changes, such as reducing administrative burdens and improving electronic health record systems. Medical students’ burnout might be triggered by specific problems related to their young age, economic situation, exam stress and workload, high academic expectations, lack of support, and others. Conclusions: Burnout is common in physicians and medical students, negatively affecting mental health, professional/academic efficacy, and patient outcomes. Addressing burnout requires a multifaceted approach, including individual strategies and systemic changes within institutions. Full article

Employee burnout levels have risen due to teleworking, increased job demands, and the lack of clear boundaries between personal and professional life. This study evaluated burnout levels, occupational health (through the presence or absence of psychosocial risk factors), engagement, and well-being/job satisfaction in a sample of employees aged over 18 from varying sociodemographic backgrounds. Additionally, we sought to explore the relationships among these variables and their influence on workplace well-being. The sample comprised 112 employees aged 18 to 65 (of both genders). The instruments used included the Burnout Syndrome Scale (Maslach Burnout Inventory—Student Survey -MBI-SS-), the DECORE multidimensional questionnaire, the Utrecht Work Engagement Scale (UWES), and the General Work Well-Being Questionnaire (qBLG). The results indicated that overall workplace well-being levels are high, while the presence of psychosocial risk factors and burnout levels are moderate to low. Most variables correlated with each other in the expected directions. Furthermore, job well-being was inversely predicted by cynicism and burnout and positively predicted by support, engagement, and control. This study highlights the importance of workplace well-being and occupational health. Our findings suggest the need for intervention programs that include strategies to motivate employees, improve the work environment, and enhance stress coping mechanisms, among other areas.

Indoor air quality (IAQ) in higher education institutions’ dormitories, without mechanical ventilation, is a significant concern for students’ health due to prolonged occupancy in cold regions. The present investigation assessed IAQ by measuring two dormitories’ CO₂, temperature, and relative humidity with the presence of one, two, three, and four occupants in the United Kingdom. Considering the possibility of natural ventilation by opening the windows in the summer, IAQ was monitored using two sensors located at 1 m and 2 m heights from the floor level of the dormitories in July. The tracer mass balance model showed close agreement with the monitored IAQ levels, with a direct relationship observed between occupant numbers and CO₂ build-up. CO₂ levels exceeded 1000 ppm within an hour during occupancy and closed ventilation, with air exchange rates between 0.12 and 0.2 h⁻¹, increasing to 1334, 1259, 1884, and 2064 ppm after 30 min with one, two, three, and four occupants, respectively. Desired IAQ standards (1000 ppm) were achieved in 13, 33, 80, and 86 min for one, two, three, and four occupants after starting natural ventilation by opening 20% of the windows. The analysis of variance affirmed the effect of occupancy on IAQ, while the impact of height (1 m and 2 m) on CO₂ levels was insignificant. This study underscores the need to effectively ventilate the partial opening of windows in dormitories to mitigate CO₂ build-up, ensuring the desired ambient environment within dormitory rooms during summers in cold regions.

After the COVID-19 lockdown, the health authorities established strict protocols for ventilating indoor spaces and reducing contagion. Although the control of the disease allowed these measures to be relaxed, indoor air quality (IAQ) and natural ventilation (NV) are still essential. However, in certain climatic conditions, this can affect the thermal comfort of the occupants. This situation is relevant in educational buildings, where thermal discomfort can influence students’ academic performance, especially during critical periods such as exams. In this context, this article explores how different NV strategies, both during and after the pandemic, affect the thermal comfort of students at a university in a Mediterranean climate zone. The analyses revealed that, despite the low temperatures and strict ventilation protocols due to COVID-19, thermal comfort during winter was higher than in spring and summer. These results led to an investigation into which variables could explain this phenomenon, detecting that the choice of clothing was crucial to achieving adequate comfort conditions. Regarding IAQ, ventilation was sufficient, even excessive, in some cases, especially during mandatory measures. In conclusion, it would be beneficial to establish ventilation protocols adapted to each environment and to advise students on individual strategies to improve their thermal comfort. Full article

Background: Despite scientific breakthroughs in vaccine development, some people remain reluctant to accept the anti-SARS-CoV-2 vaccine. This study evaluates attitudes and behaviours towards the vaccine and factors associated with refusal/hesitancy at the start of Italy’s vaccination campaign. Methods: EPICOVID19 is a two-phase observational web-based study where adult volunteers completed questionnaires in April–June 2020 and January–February 2021. Refusal/hesitancy towards the vaccine was assessed among those not yet vaccinated. We analysed factors associated with refusal/hesitancy by applying multivariate multinomial logistic regression models. Results: Among 36,820 survey participants (mean age of 51 years, 59.7% women, 63.6% highly educated), 2449 (6.7%) were against or hesitant, 4468 (12.1%) were inclined but unsure, and 29,903 (81.2%) were willing to be vaccinated. Factors positively associated with refusal/hesitancy included female sex, middle age, at-risk occupations, medium and low education, deprived status, being underweight, previous SARS-CoV-2 positivity, poor perceived health, no fear of contracting SARS-CoV-2, the fear of contaminated food and natural disasters, and low trust in science, media, government, or institutions. Low hesitancy was associated with student and retired status, overweight and obesity, moderate and high alcohol consumption, no concern about economic and working conditions, and sensitivity to climate change/environmental pollution and epidemics. Conclusions: This survey showed that, during the first month of Italy’s vaccination campaign, some individuals were reluctant to receive the anti-SARS-CoV-2 vaccine. This study highlights potential target groups for tailored communication and prevention campaigns. Full article

In parallel with the global landscape, the architecture profession is losing its appeal in Turkey, as evidenced by a decline in school occupancy rates to 79%. Accordingly, the Higher Education System (YÖK) has decreased architecture program quotas by an average of 20%. This study establishes a comprehensive model outlining the key factors influencing these orientations to better understand architecture students’ career paths. This paper investigates how architecture students’ perceptions of the construction industry influence their career choices, particularly their likelihood of staying in the sector. The devised model is empirically validated via data collected from 419 online survey questionnaires. Utilizing SPSS 23 and LISREL 8.8 software, a range of analyses, including frequency, validity, reliability, exploratory and confirmatory factor analysis, and structural equation modeling, are conducted. The model posits “intention to stay in the sector (IS)” as a dependent latent variable, affected by independent latent variables like “nature of the profession (NP)”, “prestige (PR)”, “working conditions (WCs)”, “health and stress (HS)”, “salary and benefits (SB)”, “ethical and political processes (EPs)”, “authorities and responsibilities (AR)”, and “conformity to expectations (CE)”. The findings demonstrate that NP, PR, WCs, SB, HS, EPs, AR, and CE significantly influence IS. Particularly, NP and PR substantially impact the preference for the architectural profession and the determination to remain in the sector. In contrast, WCs, HS, SB, and EPs affect IS negatively. This research contributes significantly to the literature on the career intentions of architecture students by presenting a model that captures the factors influencing their career choices. The model is supported by substantial empirical evidence and is based on a comprehensive literature review. Full article

(1) Background: With the growing severity of global environmental issues and increasing consumer health consciousness, green consumption has become a prominent focus in both research and practice. However, studies on the mechanisms of health consciousness and environmental awareness influencing the purchase intentions of sports enthusiasts toward sustainable sports products remain relatively limited. This study investigates how health consciousness and environmental awareness impact the green consumption behavior of sports enthusiasts through psychological pathways, including attitude, subjective norm, and perceived behavioral control, aiming to reveal their underlying mechanisms. (2) Methods: Based on the extended Theory of Planned Behavior (TPB), this study developed a theoretical model incorporating health consciousness and environmental awareness. Data were collected via a questionnaire survey, yielding 407 valid responses. The sample was gender-balanced (52.8% male, 47.2% female), predominantly consisting of young individuals aged 26–35 (44.7%) and 18–25 (28.0%), with primary occupations being company employees/managers (46.2%) and students/teachers (25.3%). The collected data were analyzed using SPSS and AMOS software to systematically evaluate the research hypotheses and the model’s applicability. (3) Results: The model exhibited excellent fit indices, with a χ²/df value of 2.129, an RMSEA value of 0.053, an RMR value of 0.029, and GFI, CFI, NFI, and NNFI values all exceeding 0.90, indicating that the model structure adequately explained the relationships among latent variables. All research hypotheses were significantly supported (p < 0.01), demonstrating that health consciousness and environmental awareness not only directly influence purchase intentions but also exert significant indirect effects through attitude, subjective norm, and perceived behavioral control. (4) Conclusions: Health consciousness and environmental awareness are critical drivers of sports enthusiasts’ purchasing behavior for sustainable sports products. This study deepens the understanding of the mechanisms underlying green consumption behavior and offers practical implications for related businesses. Companies should enhance product healthiness and environmental friendliness while optimizing consumer psychological perceptions to increase purchase intentions. Full article

Indoor air quality is paramount for the health and well-being of individuals, especially in enclosed spaces like office buildings, schools, hospitals, and homes where people spend a significant amount of time. Ensuring good indoor air quality is not only essential for reducing symptoms such as headaches, eye and respiratory irritation, fatigue, and difficulty in concentration, but it is also a key component of sustainable building practices aimed at promoting long-term health and environmental balance. This study aims to explore the impact of the microclimate and fungal microbiota on the health and cognitive performance of occupants in a university classroom, which is part of a cultural heritage building. The research delves into various microclimatic parameters, including temperature, relative humidity, CO₂, volatile organic compounds, O₂, and particulate matters (PM_2.5 and PM₁₀), to understand their influence on the development of microbiota and the manifestation of symptoms associated with Sick Building Syndrome. Over the course of a year-long investigation, microbiological samples were collected, revealing the presence of 19 fungal species, with Cladosporium, Alternaria, and Aureobasidium being the most prevalent genera. These species were found to thrive in an environment characterized by inadequate ventilation, posing potential health risks to occupants, such as allergic reactions and respiratory infections. Microclimatic parameter values such as mean temperature of 22.9 °C and mean relative humidity of 38.5% indicated moderate conditions for fungal proliferation, but occasional high levels of PM_2.5 and CO₂ indicated periods of poor indoor air quality, negatively influencing the comfort and health of the occupants. The questionnaires completed by 190 students showed that 51.5% reported headaches, 44.2% frequent sneezing, and 43.7% severe fatigue, linking these symptoms to increased levels of CO₂ and PM_2.5. The novelty of the study lies in the integrated approach to indoor air quality assessment in a heritage educational building, highlighting the need for improved ventilation and air management to enhance health and cognitive performance, while emphasizing sustainable indoor environment management that balances occupant well-being with the preservation of cultural heritage.

Dentist–patient communication is at the core of providing quality dental care. This study aims to review the importance, challenges, strategies, and training of dentist–patient communication. The World Dental Federation (FDI) emphasizes the importance of effective communication between oral healthcare providers and patients as a critical component of high-quality care. Effective dentist–patient communication allows dentists to accurately and effectively pass on essential medical information to patients. It improves the dentist’s efficiency, boosts self-confidence, reduces occupational stress, and minimizes the risks of complaint or litigation. Moreover, it alleviates dental anxiety and fear, helps build trust between dentists and patients, addresses patients’ needs and preferences, increases patients’ adherence to improved treatment outcomes, and ultimately leads to enhanced patient satisfaction. Nonetheless, it has been widely acknowledged that dentists universally encounter the repercussions arising from suboptimal communication strategies. Time constraints, difficulties in establishing rapport, the oral-health illiteracy of the patients, the poor communication skills of the dentists, dentists’ perceptions, and language barriers often hinder dentist–patient communication. Dentists should take the patient-centered approach as a premise and acquire verbal and non-verbal communication skills to overcome these communication barriers. The patient-centered approach comprises the understanding of patients’ illness, shared decision-making, and intervention with mindfulness of the patient’s own pace. Simple, succinct, and jargon-free language should be used in verbal communication. Proper body postures and gestures are fundamental for showing positive attitudes towards patients. Communication training for dental students should involve a structured pedagogical approach that includes didactic instruction, role-playing exercises, patient interviewing, and ongoing assessments. Key components of effective communication skills training in dental education include motivational interviewing, open-ended questioning, affirmations, reflective listening, and summaries to enhance patient engagement and adherence to treatment plans.
