Achieving optimal daylighting in buildings necessitates complex and expensive control systems. This research addresses this challenge by proposing a simple and more practical solution: a parametric louver system based on rotating slats controlled by stepper motors, powered by an Integrated Circuit platform (Arduino board), which can translate the digital figures (the rotation angles) to a physical action. The system automatically adjusts the slats in accordance with solar altitudes and reflects them to specific targets over the ceiling. This ensures a uniform and comfortable distribution of daylight throughout a room. This system was developed using Grasshopper as the parametric software, with future control planned via a user-friendly mobile app through a preliminary prototype. This daylighting system prioritises human visual comfort while targeting a significant 53% reduction in electrical lighting energy consumption. The system aims to enhance occupant well-being to significantly increase energy savings, making it a compelling solution for sustainable building design. Full article

Background: This study examined changes in psychological adjustment among patients with Anorexia Nervosa (AN) and Binge Eating Disorder (BED) following a 3-week inpatient multidisciplinary (disease-tailored) rehabilitation program. Methods: twenty consecutive Italian female adults with a diagnosis of AN (mean age ± SD: 25.9 ± 9.4 years; mean Body Mass Index: BMI: kg/m²: 15.8 ± 1.61) and fifteen consecutive Italian female adults with diagnosis of BED (mean age ± SD: 43.5 ± 15.3 years; mean Body Mass Index: BMI: kg/m²: 41.1 ± 7.82) were admitted to the study. Psychological functioning and well-being were assessed pre- and post-intervention using the Strengths and Difficulties Questionnaire and the Psychological General Well-Being Index. Results: Significant improvements in emotional symptoms [F(1, 31) = 21.1973, p < 0.001, ƞ²p = 0.406] and overall psychological functioning [F(1, 31) = 10.0062, p = 0.373, ƞ²p = 0.026] were observed in both groups, with the most pronounced changes in internalizing symptoms, such as anxiety and depression. Changes in BMI were significantly associated with emotional symptoms, vitality [F(1, 31) = 4.89, p = 0.035, ƞ²p = 0.136], and total well-being scores [F(1, 31) = 6.341, p = 0.017, ƞ²p = 0.170]. By contrast, no significant changes were observed in domains such as behavioral problems, hyperactivity/inattention, and peer relationships, probably indicating the need for more prolonged and targeted, domain-specific interventions. Conclusions: A 3-week inpatient multidisciplinary program was associated with improvements in internalizing symptoms and psychological well-being in women with AN and BED. Domains such as behavioral regulation and social functioning showed limited change, indicating the need for longer and targeted psychosocial components. Full article

Microplastic (MP) pollution in urban areas is a growing global concern due to its health risks and environmental effects. This study investigates the sources, spatial distribution, and health risks of MPs in road dust across industrial, capital city, and peri-urban areas of Bangladesh. Street dust samples were collected from 15 heavily congested traffic sites across Dhaka and its surrounding areas. The samples were analyzed using fluorescence microscopy and Fourier Transform Infrared (FTIR) spectroscopy to identify MP types and their morphological characteristics. We have identified six types of polymers, including Polyvinyl alcohol (PVA), Polyethylene (PE), Polypropylene (PP), Polystyrene (PS), Low-Density Polyethylene (LDPE) and High-Density Polyethylene (HDPE), with industrial areas exhibiting the highest levels of MPs followed by capital city and peri-urban zones. PP was the most prevalent MP polymer, with the highest level in industrial areas (14.1 ± 1.7 MPs/g), followed by capital city (9.6 ± 1.92 MPs/g) and peri-urban areas (7.2 ± 1.56 MPs/g). Principal Component Analysis (PCA) identified traffic emissions, industrial activities, and mismanaged plastic waste as the primary sources of MPs. Health risk evaluations indicated that children are more susceptible to MP exposure through ingestion and inhalation, with industrial areas posing the highest carcinogenic risk. The findings underscore the pressing demand for better waste management systems and stricter regulatory measures to mitigate MP pollution and safeguard public health in urban environments. Addressing these challenges is essential to reduce the growing threat of MPs and their long-term effects on ecosystems and human well-being. Full article

Background/Objectives: Cardiorespiratory fitness (CRF) represents a strong and consistent predictor of mortality among adults. It is ideally expressed as the maximum or peak rate of oxygen consumption per kilogram of body mass (VO_2max) determined by the cardiopulmonary exercise test (CPX). Variance in CRF is mainly attributable to genetics and physical training; nevertheless, strong behavioral and socioeconomic confounders need to be considered. Among those, psychosocial stress may play an important role. Some papers show an association between low CRF and chronic stress conditions; nevertheless, CRF is generally estimated by indirect assessment and not directly measured by CPX. Methods: CRF was directly assessed by performing a CPX in 145 consecutive subjects (56 male, 89 female) (age 19–65 years) who attended our Exercise Medicine unit for health check-ups. Weekly total volume of physical activity (PA) was evaluated using a validated questionnaire (IPAQ); perceptions of stress, fatigue, and somatic symptoms were assessed using a self-administered questionnaire. Results: VO_2max was negatively correlated with perception of stress (p = 0.03), fatigue (p < 0.001), and somatic symptoms (p < 0.001); as expected, it was positively correlated with the weekly volume of PA (p < 0.001). This link was further evidenced by the observation that subjects who did not meet the PA goals as indicated by WHO guidelines presented a higher perception of stress, fatigue, and symptoms, as compared to physically active subjects. Conclusions: This direct link might, on the one hand, corroborate the role of exercise as a tool to manage stress and, on the other hand, focus on the role of stress as a possible determinant of CRF.

This study investigates the impact of servant leadership on employee performance in mobile telecommunications providers, emphasizing the mediating role of organizational trust and its implications for organizational sustainability. Leadership effectiveness is particularly critical in environments where trust is limited, as it shapes both immediate performance and long-term organizational resilience. Using survey data from 375 employees across three telecom companies in Iraq, the results indicate that servant leadership is positively related to employee performance. Mediation analysis further demonstrates that organizational trust significantly transmits the effect of servant leadership on performance. These results extend current knowledge of leadership dynamics in the telecom sector and underscore the role of trust-based leadership in fostering sustainable organizational outcomes. Based on these insights, a practical framework was developed to integrate servant leadership principles into team-building initiatives, leadership development programs, and organizational systems. This framework not only supports the training of future leaders but also strengthens employee well-being, ethical culture, and long-term sustainability in the telecommunications industry.

Background: Musculoskeletal disorders are disorders that affect bones, muscles, and joints, significantly impacting quality of life and academic performance. Medical students are particularly susceptible to these conditions due to academic overload, inadequate posture, and overuse of digital devices. Objectives: This study aimed at investigating the prevalence of musculoskeletal disorders and associated factors among medical students at a university centre in northwestern São Paulo State. Materials and Methods: This cross-sectional, descriptive, and analytical study involved administering a structured questionnaire and conducting clinical tests (Phalen and Finkelstein) to assess musculoskeletal disorders in 164 students. Data were analyzed using the chi-square test with a significance level of 5% (p-value < 0.05). Results: The results indicate a high incidence of musculoskeletal disorders primarily affecting the upper back, neck and shoulders. In addition, prolonged use of mobile phones and tablets and predominantly typing with the thumbs were found to be associated with an increased risk of De Quervain’s tenosynovitis. A high rate of self-medication was also observed among students, with few participants seeking medical care. These findings highlight the importance of implementing preventive strategies early in the undergraduate curriculum, emphasizing ergonomics and musculoskeletal health awareness. Conclusions: This proactive approach can significantly minimize the negative impact on students’ well-being throughout their training and subsequent professional careers. Further studies might explore ergonomic interventions and educational programmes to reduce the incidence of these disorders. Full article

STEM (Science, Technology, Engineering & Mathematics) programs hold significant social and economic relevance, as the technological innovation that sustains a country’s competitiveness depends on them. This article compares research on STEM programs in Portuguese- and Spanish-speaking countries, specifically Brazil, Chile, Portugal, and Spain. More specifically, it aims to reflect on the social and economic relevance of STEM programs; vocational choices and the social stereotypes associated with these fields; the variables that influence academic success, retention, and graduation rates; and the measures implemented, either nationally or by Higher Education Institutions (HEIs), to promote access and success in these programs. We conducted qualitative research, analyzing official documents and peer-reviewed articles that describe the higher education landscape in the selected countries. Results show that in all four countries studied, there is a growing demand for STEM graduates. However, concerns remain about high dropout and failure rates, as well as the lower participation of women and students from disadvantaged socioeconomic backgrounds or ethnic minorities. Some measures have been implemented by the governments of these countries to promote greater democratization of access and academic success for these students. Nevertheless, inequalities persist, suggesting the need to increase investment in practices and policies that encourage young people, especially those from more disadvantaged groups, to engage early in STEM domains.

Background: Scientific literature highlights that practitioners and policymakers in social and educational fields can contribute to the inclusion and empowerment of vulnerable groups when developing actions grounded in scientific evidence of social impact, co-created through dialogic engagement with the concerned communities. This study, aligned with Sustainable Development Goals 4 (“Quality Education”) and 5 (“Gender Equality”), provides new evidence on the co-creation process between policymakers and practitioners and women without higher education degrees and its impact. Methods: A qualitative study was conducted through nine in-depth interviews with practitioners and policymakers engaged in the development of dialogic spaces in education, health, and equality. Results: Two key characteristics were identified: (1) a focus on the inclusion of women not yet involved, through the co-creation of egalitarian spaces for dialogue and decision-making, and (2) a commitment to implementing actions based on scientific evidence of social impact. These led to reported improvements in empowerment, education, well-being, health, and employability, not only for the women themselves but also for their families, schools, and communities. Conclusions: The findings support the promotion of co-creation processes with women without academic qualifications and in vulnerable situations, demonstrating their potential to foster sustainable social development.

Pet humanization, particularly in dogs and cats, has transformed animal healthcare and highlighted the importance of nutrition in promoting human–pet social interaction, pet psychophysical well-being and, possibly, longevity. Nutraceuticals, such as omega-3 fatty acids, prebiotics, probiotics, plant extracts and dietary supplements, are endowed with antioxidant, anti-inflammatory, immune-modulating, cognitive-enhancing and gut-microbiota balancing properties. These effects have been shown to contribute to the possible prevention and management of bone and skin diseases, as well as gastrointestinal and behavioral disturbs. Moreover, the human–animal bond has been shown to play a pivotal role in reducing stress, improving sociability, and modulating pets’ emotional and physiological states. Evidence also suggests that nutrition and social interactions can influence the gut–brain axis, impacting the behavior, cognition, and resilience to stress-related disorders. Besides underlining the value of nutraceutical integration into pet nutrition strategies and offering a comprehensive, evidence-based perspective on their potential in improving animal welfare, literature reports about drawbacks of the use/misuse of such substances have been reported.

Background and Clinical Significance: The occurrence of acute myeloid leukemia (AML) in pregnancy represents a diagnostic and management challenge in the attempt to balance and achieve both maternal and fetal wellbeing. Pregnancy-specific manifestations mimic the initial symptoms of leukemia and may lead to a delay in diagnosis, especially during the first trimester of pregnancy. Decision-making strategies involve the patient and couples counseling with a multidisciplinary team of hematologists, obstetricians, neonatologists and psychologists. Maternal outcome depends on the disease subtype, progression and response to medication. Fetal outcome depends on other potential pregnancy complications, possible teratogenicity, gestational age at delivery and sometimes iatrogenic prematurity. Case Presentation: We present the case of a 38-year-old multiparous patient with a late first trimester, with an AML diagnosis presenting with hyperemesis gravidarum-like symptoms. Genetic testing revealed the presence of an Fms-like tyrosine kinase 3-internal tandem duplication mutation (FLT3-ITD). Following that, a repeatedly refused termination of pregnancy and rapid disease progression with azacitidine therapy was initiated. Elective cesarean delivery was performed at 34 weeks of gestation due to progressive leukocytosis, which persisted postpartum, requiring the use of first-, second-, and eventually third-line chemotherapy. Fetal outcome was favorable at 3 months postpartum. Conclusions: Cases of AML in pregnancy require a tailored approach according to guidelines, but also patient/couple preferences, while the choice of chemotherapy is limited considering its potential teratogenic effects. This is a case with a misleading first presentation and a challenging therapeutic choice due to its genetic subtype and maternal treatment postponement. Full article

Background: Breast reconstruction following mastectomy plays a crucial role in breast cancer management, restoring physical form and significantly impacting psychological well-being and quality of life. Implant-based breast reconstruction (IBBR) is the most performed technique worldwide due to its relative simplicity, shorter operative times, and avoidance of donor site morbidity. Achieving satisfactory aesthetic outcomes, however, remains challenging, as multiple factors—including patient characteristics, surgical technique, implant selection, timing of reconstruction, and adjuvant therapies—can influence the final appearance. Methods: Literature research was performed via PubMed, Scopus and Cochrane Library Database, focusing on studies examining aesthetic outcomes in implant-based breast reconstruction published between 2015 and 2025. Data on type of study, sample size, aesthetic evaluation methods, and duration of follow-up were collected and summarized. Results: Among 747 articles identified, only 25 articles fulfilled inclusion criteria, including mostly retrospective studies, but also prospective studies, randomized clinical trials, and reviews. Factors such as BMI, inframammary fold management, and implant selection were consistently reported to influence aesthetic outcomes. Surgical techniques including ADM use, axillary advancement sutures, hybrid reconstruction with fat grafting, and prepectoral implant placement were associated with improved patient satisfaction. Patient satisfaction often differs from surgeon-assessed outcomes, emphasizing the importance of subjective evaluation. Conclusions: Despite the heterogeneity and retrospective nature of many studies, evidence indicates that optimizing aesthetic outcomes in IBBR relies on careful patient selection, tailored surgical planning, and meticulous use of evidence-based techniques, including implant selection, flap-based support, and adjunctive strategies. Patient-reported outcomes are essential for evaluating success, and future research should focus on standardized outcome measures and prospective studies to further refine reconstructive approaches and maximize both cosmetic satisfaction and quality of life.

Background: Allergic diseases, such as allergic rhinitis, eczema, and asthma, are prevalent among adolescents and are associated with various health concerns, including poor sleep quality and mental health problems. Although previous research has investigated the general association between allergic conditions and sleep disturbances, few studies have examined how allergic diseases relate to sleep duration. Methods: We performed secondary analysis of the data obtained from the 19th Korea Youth Risk Behavior Survey (2023), which included 52,880 middle and high school students. Data was analyzed using complex sample design techniques, descriptive statistics, t-tests, and analyses of variance and covariance conducted to explore associations between allergic diseases and sleep duration on weekdays. Covariates included sex, school type, academic performance, socioeconomic status, and residential type. Results: The average weekday sleep duration among adolescents was 6.2 h, which was significantly shorter than that recommended by the U.S. Centers of Disease Control and Prevention (8–10 h). Among allergic conditions, allergic rhinitis was significantly associated with reduced sleep duration (p = 0.001), unlike asthma (p = 0.119) and eczema (p = 0.586). Additional differences in sleep duration were observed by sex, academic performance, socioeconomic status, and living arrangements. Conclusions: Managing allergic rhinitis may be crucial to promoting adequate sleep during adolescence. Furthermore, future research should incorporate physiological indicators to assess sleep quality, as self-reported measures may not capture sleep disturbances such as night-time awakenings. These findings can inform the development of integrated health strategies to enhance physical and psychological well-being of adolescents. Full article

Background: This exploratory, non-randomized pre–post study compares three school-based stress interventions—Yoga, Climbing, and Social–Emotional Learning—in primary school children. Methods: We compared three low-threshold interventions delivered during regular lessons: (1) a six-week video-guided Yoga sequence (n = 64; grade 3), (2) a 2.5-week social–emotional learning (SEL) module focused on emotion recognition and regulation (n = 60; grade 3), and (3) a two-week Climbing program implemented with a small special-education sample (n = 12). Parallel class-matched controls were included for Yoga and SEL (n = 64 and n = 60, respectively). A quasi-experimental pre–post design was used. Primary outcomes were overall stress and the emotion subdomains of anger, anxiety, and sadness (SSKJ 3–8); the secondary outcome for the Climbing pilot was general self-efficacy (SWE). Non-parametric statistics (Wilcoxon signed-rank, Mann–Whitney U) and rank-biserial effect sizes (r) were reported with Holm-adjusted α = 0.05. Results: Yoga and SEL produced significant within-group reductions in overall stress and all emotional subdomains (all p < 0.001; r = 0.59–0.75) and outperformed their respective controls at post-test (p ≤ 0.038; r = 0.22–0.48). Change-score comparisons between Yoga and SEL were not statistically different (p ≥ 0.44). In the exploratory Climbing group, self-efficacy increased significantly (V = 64.5, p = 0.006, r = 0.80); stress outcomes mirrored Yoga/SEL trends but were under-powered. Conclusions: A brief classroom Yoga routine and a condensed SEL module each yielded clinically meaningful reductions in stress among primary-school pupils, offering flexible options for post-pandemic recovery. Preliminary evidence suggests that Climbing may enhance self-efficacy in older students with psychological challenges; however, larger samples are required. Integrating cost-effective physical and emotional strategies can help schools promote resilience and well-being amid ongoing educational disruptions. Full article

Background/Objectives: Difficulties in emotional regulation are recognized as a risk factor for a variety of emotion-based psychopathologies, including anxiety and depression. In this context, movement and physical activity have been identified as a key element in preventing these health issues, particularly during the initial teacher training. This study aimed to analyze the impact of an emotional health physical education program on the Emotional Intelligence of university students studying physical education in Chile. Methods: A quasi-experimental design with experimental and control groups and repeated measures (pre test-post test) was employed. A total of 214 male and female students from two Chilean universities participated and completed the Spanish version of the Trait Meta-Mood Scale (TMMS-24). Results: Results confirmed the program’s effectiveness in fostering Emotional Intelligence, revealing statistically significant improvements (p < 0.05) in the dimensions of emotional attention and clarity. Conclusions: These findings suggest that emotional physical education programs can be effective in promoting emotional skills essential for the learning and mental well-being of university students who will later become primary and secondary school teachers.
