Background: College students’ well-being is a critical determinant of academic success, and for Native American students, cultural strengths, resilience, and community support are key in fostering persistence in higher education. Alongside these assets, health behaviors are key contributors to psychological well-being (PWB) and academic performance. This study examined how modifiable health behaviors, such as physical activity (PA) and sleep duration, relate to PWB and academic performance among Native American college students. Methods: A secondary data analysis was conducted using a nationally representative sample of Native Americans (N = 1914) from the Spring 2023 American College Health Association-National College Health Assessment (ACHA-NCHA) survey. Independent variables include meeting PA guidelines (≥150 min moderate or ≥75 min vigorous/week) and sleep duration (categorized as poor or good). The Diener Flourishing Scale measured PWB. Academic performance was measured based on self-reported cumulative grade averages. Findings: Biological sex and PA were significantly associated, χ² = 40.60, p < 0.001, with a higher proportion of males meeting PA guidelines. Students with good sleep reported higher PWB than others, F(1, 1817) = 62.08, p < 0.001. Similarly, students who met PA guidelines reported higher PWB, F(1, 1817) = 35.71, p < 0.001. Poor sleep was associated with lower odds of higher academic performance (B = −0.33, p < 0.001). Contrarily, PA was not significant (p = 0.350). PWB was positively associated with academic performance (B = 0.031, p < 0.001). Conclusions: Sleep and PWB are key factors associated with both PWB and academic performance, while PA is associated with PWB. These findings highlight the importance of relevant interventions that promote these factors to support overall well-being, academic success, and retention among Native American college students.

Background: Sustaining long-term lifestyle change remains a major challenge in preventive health. Epigenetic clocks offer a dynamic, modifiable measure of biological ageing that may enhance motivation when returned to individuals. Objectives: This study had two aims: (1) to evaluate whether personalised health reports integrating epigenetic age, polygenic cancer risk scores, and lifestyle metrics could motivate sustained behavioural change; and (2) to examine variability across epigenetic clock generations to inform the selection of a suitable model for participant feedback. Methods: A total of 178 adults were recruited via the Graham Fulford Charitable Trust community testing programme, and 91 completed a one-year follow-up survey assessing behavioural, psychological, and knowledge-related outcomes. DNA methylation data from 140 samples were used to compare 14 epigenetic clocks across four generations. Results: Most participants reported positive lifestyle changes, including feeling healthier (72.5%), increased physical activity (60.4%), and improved diet (47.3%). Gains were also observed in health knowledge (63.7%) and psychological well-being (31.9%). Epigenetic clock comparisons revealed substantial heterogeneity across models. Zhang2019-BLUP was selected as a stable and interpretable measure of biological age that can be readily communicated to participants, supporting empowerment and improved health literacy, rather than serving only as a risk prediction metric. Conclusions: Personalised biomarker feedback including epigenetic age combined with lifestyle and wearable data can support self-reported improvements in health-related behaviours. Community-based delivery through trusted local networks proved effective. The marked variation between epigenetic clocks highlights the importance of selecting models designed for clear communication when used in public-facing health interventions. Full article

This systematic review examines the use of plant-derived extracts as antibacterial and antifungal agents in medical textiles, with an emphasis on active components, extraction techniques, biological efficacy, target microorganisms, and fabric application methods. This study is framed within the context of natural resource-based plant biomass and agro-industrial residues as a sustainable source of high-value functional compounds for resource valorization. Searches in Scopus and Web of Science followed the PIOC framework and PRISMA protocol. From an initial 389 records, 38 studies met the eligibility criteria. We identified a sustained growth in publications between 2020 and 2025, and six predominant thematic lines related to medical textiles, sustainability, antimicrobial assessment, structural characterization, natural dyeing optimization, and antioxidant functionalization. Among the most studied species, Aloe barbadensis and Salvia officinalis were prominent. Leaves were the most frequently used plant organ, highlighting their relevance as readily available renewable biomass resources. Maceration was the most common extraction method, although ultrasound-assisted extraction yielded a broader metabolite profile and better preserved thermolabile compounds, demonstrating the impact of biomass conversion techniques on resource efficiency and extract quality. Cotton 100% (plain weave) was the most widely used substrate, and the exhaustion method (immersion/exhaust dyeing) was the preferred application technique. Overall, plant extracts obtained through the sustainable management and valorization of plant resources achieved high inhibition against pathogenic bacteria, including resistant strains, and consistent antifungal activity, supporting their potential for developing functional and sustainable medical textiles. These findings align with the goals for responsible production and good health and well-being and reinforce the role of biomass-based resource systems within a circular bioeconomy, opening avenues to optimize formulations, standardize methodologies, and evaluate post-laundering performance and in vivo biocompatibility.

A rare clinical condition associated with numerous diagnostic and treatment challenges, pregnancy-associated melanoma (PAM), is defined as melanoma diagnosed either during pregnancy or within the first year postpartum. The physiological changes in pregnancy (hormonal changes and immune modulation), along with the normal changes in the pregnant woman’s skin (skin color changes, etc.), may all hinder early detection of this disease and create concerns regarding the advancement of melanoma and the well-being of both the mother and her fetus. The purpose of this review article was to summarize the current literature on the incidence, biology, diagnostic methods and treatments of PAM, with an emphasis on comparison between the two forms of melanoma. More recent research indicates that pregnancy itself is not typically associated with decreased melanoma-specific survival rates. However, when worse results are reported, it appears that this may be more due to delays in initial diagnoses (diagnosis of cancer after delivery) or detection of cancer postpartum, as well as the increased number of stages of melanoma at which women were diagnosed at the time of their first evaluation compared to non-pregnant controls, rather than being a result of enhanced biologic aggressiveness in melanoma driven by pregnancy itself. The preclinical and translational models have suggested that pregnancy may influence melanoma biology through the mechanisms of hormonal signaling, immune system modulation and vascular remodeling; however, these mechanisms remain hypothesis-generating, and current clinical evidence does not indicate that changes in hormone levels during pregnancy negatively affect melanoma survival. Surgical excision is the mainstay of treatment and can be performed safely during pregnancy. In select patients, a sentinel lymph node biopsy may also be performed. Due to the risk of fetal harm, systemic therapy (targeted agents and/or immune checkpoint inhibitors) cannot be used for the treatment of PAM during pregnancy. Post-pregnancy treatment of PAM will follow standard melanoma treatment guidelines; however, the treatment options will need to take into consideration whether or not the patient is breastfeeding and if she desires to become pregnant again in the future. In summary, PAM will require a multidisciplinary, individualized approach to maximize oncologic outcomes while protecting the health of both the mother and her fetus. Awareness of this disease and timely diagnosis are critical to maximizing the prognosis. Full article

Sports participation is a widely recognized facilitator of physical health, mental well-being, and social inclusion, but persistent and substantial disparities have been observed across socioeconomic groups. Focusing on Japan, this study examined the socioeconomic determinants of sports participation, particularly the roles of gender, age, employment, and caregiving responsibilities. It used nationally representative repeated cross-sectional data to analyze participation rates and annual participation days across multiple sports at the population-segment level, defined by combinations of demographic and social attributes. Results revealed prominent sport-specific gender differences, heterogeneous age effects across sports, significant age–gender interaction effects, and distinctive behavioral changes during the COVID-19 pandemic. During the pandemic, participation in competitive and group sports declined with age, but walking increased among middle-aged and older adults. In addition, constraints in employment and caregiving had limited overall effects but significantly reduced engagement in walking. These findings suggest the crucial influence of the interaction among social roles, life-stage transitions, and historical context, rather than biological sex differences alone, on sports participation patterns, highlighting the urgency of designing sports policies as inclusive social interventions that consider diverse motivations and limitations across population groups.

Eutrophication is a pervasive issue in Mediterranean reservoirs, where external nutrient inputs and internal sediment releases interact to impair water quality and ecological stability. This study assessed the trophic condition of the artificial lake Cuga in Sardinia (Italy), mainly used for irrigation and providing potable water, by integrating watershed nutrient load estimates, inter-lake transfers, and internal phosphorus release. Field campaigns between July 2022 and May 2023 provided bi-monthly measurements of physical, chemical, and biological parameters, complemented by GIS-based land cover analysis and export coefficient modeling to quantify spatial nutrient sources. Additional phosphorus inputs from water transfers with a nearby reservoir were calculated, while internal sediment release was estimated using a calibrated mass balance model. Results revealed high nutrient concentrations, with mean total phosphorus of 128 mg P m⁻³, chlorophyll a averaging 9.9 mg m⁻³, and Secchi depth below 1 m, classifying the reservoir as eutrophic to hypertrophic under OECD and Carlson indices. Spatial loads were dominated by agricultural areas, while inter-lake transfers and internal sediment release contributed substantially to the overall phosphorus budget. The predictive Vollenweider model closely matched the observed conditions, confirming the robustness of the combined approach. Maintaining good ecological status in Mediterranean reservoirs is essential for safeguarding human well-being, as eutrophication degrades drinking-water quality, increases treatment costs, and can promote toxin-producing algal blooms with direct implications for public health. These findings highlight the need for integrated management strategies addressing both external and internal nutrient sources to mitigate eutrophication in Mediterranean reservoirs, which affects the ecosystem functioning and the related human needs and well-being.

Background: Dentists constitute one of the most heavily burdened groups of healthcare professionals, experiencing high levels of musculoskeletal disorders, occupational stress, burnout, and diminished quality of life. Although extensive literature addresses these issues, no study has directly examined biological age or epigenetic markers of aging in this population. This narrative review, informed by systematic methodological principles, seeks to fill this gap by connecting established occupational stressors with contemporary concepts of biological aging and chronomedicine, ultimately proposing a preventive well-being framework specifically for dentists. Methods: A narrative review informed by systematic methodology was conducted following PRISMA 2020 guidelines. Searches in PubMed, Scopus, and the Cochrane Library (2015–2025) used combined keywords and MeSH terms related to lifestyle factors, occupational stress, musculoskeletal disorders, quality of life, and wellness among dentists. Of the 943 records identified, 15 met the inclusion criteria and were assessed for outcomes, methodological quality, and relevant risk factors. Results: The included studies consistently indicated a significant occupational burden, with musculoskeletal pain, emotional exhaustion, anxiety, and depersonalization as frequent findings. Quality of life was generally moderate to low, especially regarding mental health. Lifestyle patterns were characterized by inadequate sleep, limited physical activity, irregular eating habits, and insufficient recovery. These conditions-chronic stress, poor sleep, inactivity, and suboptimal nutrition-are recognized accelerators of biological aging, implying that the professional demands of dentistry may adversely influence the biological clock. Although none of the studies measured biological age directly, the collective evidence underscores the need for preventive strategies informed by chronomedicine. Conclusions: This review highlights a critical gap in the dental literature: the complete absence of biological-age assessment in a professional population exposed to multiple aging accelerators. Integrating occupational health data with modern concepts of biological aging and chronomedicine, the study proposes a targeted preventive framework to regulate biological rhythms, reduce cumulative biological deterioration, and improve the long-term quality of life and professional sustainability of dentists.

Building lighting has a significant impact on occupant health and well-being, energy efficiency, spatial perception, and visual comfort. Many current building lighting systems, however, continue to be insufficiently responsive to changing environmental conditions and human-centric demands, leading to ineffective energy use, poor visual quality, and disruption of the circadian rhythm. This disparity highlights the need for modern buildings to incorporate integrated, intelligent, and sustainable lighting design strategies. This review offers a methodical examination of current, emerging and future developments in building lighting research in six related fields within an architectural scope of building design and performance. To assess lighting effectiveness, it first examines both qualitative and quantitative performance metrics, including illuminance, luminance distribution, glare, color quality, and user comfort. Second, it examines lighting control systems that use tunable light sources that can dynamically change the spectral composition and intensity in response to task demands, occupancy patterns, and daylight availability. Third, the study examines circadian-centric lighting strategies, focusing on digital modeling and simulation approaches that capture real-world lighting conditions and biological reactions. Fourth, the function of virtual reality and sophisticated visualization tools is examined, emphasizing their role in design decision-making and pre-implementation assessment. Fifth, a critical evaluation is conducted of the expanding use of machine learning and data-driven techniques in adaptive lighting control, prediction, and optimization. Limited real-time adaptability, inadequate personalization, disjointed simulation frameworks, and poor integration of human-centric metrics with intelligent control systems are some of the major research gaps. Sustainable Development Goal (SDG) 7, SDG 11, and SDG 3 are in line with the review, which ends with a summary of future paths toward intelligent, energy-efficient, and human-centered building lighting systems.

The term “plant awareness disparity”, also referred to as “lack of plant awareness”, describes a tendency for individuals to overlook and underestimate plants, especially compared to animals. This phenomenon is still referred to in parts of the literature as “plant blindness”, a term increasingly replaced due to its ableist connotations, which was introduced to capture the idea that people often fail to notice plants in their surroundings or recognize their significance for environmental sustainability and human well-being. Research has shown that this lack of awareness manifests in several interconnected ways, including: (a) failure to notice plants in everyday environments, (b) limited understanding of fundamental concepts in plant biology and ecology, (c) a tendency to undervalue or misunderstand the unique biological features of plants—such as their growth patterns, physiological processes, and adaptive strategies—and (d) the perception of plants as less complex than or inferior to animals. Plant awareness disparity has been linked to multiple contributing factors, including evolutionary, biological and educational factors. These influences reinforce anthropocentric and zoocentric views of nature, shaping how individuals conceptualize living organisms and their relative importance. In this entry, we trace the historical evolution of the concept from plant blindness to lack of plant awareness, examine the cognitive, evolutionary, and educational factors that contribute to its persistence, and discuss its broader implications for education and sustainability.

The Green Oasis (GRO) Project is a targeted urban greening intervention designed to evaluate the environmental and health impacts of compact, high-density plantings in dense built environments. Initiated in downtown Louisville, the project transformed Founders Square, a 0.64-acre sparsely planted park, into a microforest (“Trager Microforest”), a multilayered planting of 119 trees and more than 200 shrubs. The impact of this intervention is being assessed through a randomized crossover study in which participants walk in the microforest and a nearby impervious parking lot. Physiological outcomes include heart rate, heart rate variability, arterial stiffness, and stress biomarkers measured in saliva, urine, and sweat. Environmental conditions are continuously monitored by fixed and mobile weather stations, air pollution sensors, and biodiversity surveys. Baseline assessments were conducted in 2023 and 2024, with post-planting evaluations now underway (2025–). Power calculations indicate adequate sensitivity (n ≈ 40–50) to detect changes in cardiovascular stress responses in participants. Complementary ecological measurements include soil microbiome composition, greenhouse gas fluxes, and avian diversity. This study addresses critical gaps in understanding how small-scale, high-density greening interventions affect cardiovascular resilience, stress physiology, and microclimatic regulation. By integrating environmental, biological, and human health data, GRO establishes a comprehensive framework for evaluating the efficacy of urban microforests as nature-based solutions. The results are expected to inform urban planning, public health strategies, and climate adaptation policies, demonstrating how compact greening interventions can simultaneously mitigate heat, reduce pollution, enhance biodiversity, and promote human wellbeing in dense urban cores.

Background: Healthcare professionals experience continuous biological and psychosocial stressors that may disturb oral and systemic homeostasis. Alterations in salivary secretion, mucosal immunity, and microbiome composition reflect adaptive cellular responses to chronic occupational stress. Understanding these mechanisms may provide a biological framework for resilience and wellbeing in everyday clinical practice. Objective: To narratively review the evidence linking oral cellular and molecular mechanisms—salivary biomarkers, epithelial and immune cell activity, and microbiome dynamics—with stress, fatigue, burnout, and wellbeing outcomes among healthcare professionals. Methods: This narrative review employed a PRISMA-guided literature search of PubMed, Scopus, Web of Science, and Cochrane Oral Health to enhance transparency and coverage across databases. Given the heterogeneity of study designs and outcomes, data were synthesized thematically without quantitative pooling or formal meta-analysis. Methodological strength was evaluated qualitatively, focusing on biomarker validity, sampling conditions, and conceptual relevance. Eligible designs included observational, experimental, and interventional studies. Results: Evidence from 99 studies suggests that chronic occupational stress elevates salivary cortisol, oxidative stress markers, and pro-inflammatory cytokines (IL-6, TNF-α), while reducing protective salivary immunoglobulin A and microbiome diversity. Balanced oral immune and microbial profiles were associated with better psychological adaptation and lower fatigue indices. Conclusions: Oral cellular homeostasis offers a promising window into the biological underpinnings of occupational stress and resilience in healthcare professionals. Systematic integration of salivary and mucosal biomarkers into workplace wellbeing programs could enhance early detection of dysregulated stress physiology. Future interdisciplinary research should bridge oral biology, occupational medicine, and mental health to strengthen sustainable wellbeing strategies across the health workforce. Full article

Background: Perimenopause is characterized by pronounced fluctuations in ovarian steroids, which are associated with an increase vulnerability to anxiety symptoms. Growing evidence indicates that declining estrogen levels influence gut microbiota composition and microbial metabolic activity, thereby modulating neuroimmune and neuroendocrine pathways involved in emotional regulation. This review explores gut microbiota alterations occurring during the menopausal transition and critically evaluates dietary strategies targeting microbiota–gut–brain mechanisms potentially relevant to perimenopausal anxiety. Methods: A structured literature search was conducted in PubMed, Scopus, and Web of Science to identify clinical, translational, and preclinical studies addressing: (i) gut microbiota changes across perimenopause and menopause; (ii) microbiota–gut–brain pathways implicated in anxiety; and (iii) dietary patterns, nutrients, probiotics, and prebiotics with documented microbiota-modulating effects. The available evidence was synthesized narratively, with particular attention to biological plausibility and clinical relevance. Results: The perimenopause transition is associated with reduced microbial diversity, depletion of Lactobacillus, Bifidobacterium, and short-chain fatty acid (SCFA)-producing taxa, and enrichment of pro-inflammatory microbial signatures. These alterations are linked to increased intestinal permeability, altered tryptophan-kynurenine metabolism, immune activation, and dysregulated hypothalamic–pituitary–adrenal axis activity. Dietary interventions, including Mediterranean-style diets, fiber- and polyphenol-rich foods, fermented products, and selected probiotic and prebiotic formulations, have been shown to modulate gut microbial composition, enhance SCFA production, and attenuate inflammatory and neuroendocrine stress pathways. Preliminary evidence suggests potential anxiolytic benefits; however, randomized controlled trials specifically targeting perimenopausal populations remain limited. Conclusions: Gut microbiota dysbiosis may contribute to anxiety vulnerability in perimenopausal women through interconnected immune, metabolic, and neuroendocrine mechanisms. Dietary modulation of the intestinal microbiota represents a biologically plausible and low-risk complementary approach to support emotional well-being during this transitional period. Well-designed, perimenopause-specific clinical trials are needed to confirm efficacy and inform microbiome-based nutritional strategies. Full article

Exposure to poly- and perfluoroalkyl substances (PFASs) has been a cause for concern for decades due to evidence linking exposure to these substances with adverse health effects. Its widespread use in industrial and consumer products combined with their persistence in the environment poses a toxicological and regulatory challenge. Due to its ubiquity, resistance to degradation, and accumulation in biological systems, humans are exposed to a mixture of multiple PFASs, which complicates the analysis of exposure effects. As PFASs pose a risk to human health, it is crucial to study their impact during vulnerable periods, such as pregnancy. In this regard, understanding the impact of PFASs on the placenta is essential, as they can affect both pregnancy and the well-being of the developing fetus. This article reviews the current evidence linking PFAS exposure with altered placental function, focusing on the affected molecular pathways. Furthermore, we examine current methodologies for analyzing the effects of exposure to complex mixtures and explore how these approaches could be employed to evaluate the potential impact of such mixtures on placental function in the context of real-life exposure to these chemicals.

Integrative frameworks such as ‘One Welfare’ and ‘One Biology’ address the interconnectedness of animal welfare, human wellbeing, and environmental conditions by emphasising systemic interactions and shared biological mechanisms across species. Although grounded in scientific evidence, these approaches risk conceptual anthropomorphisation, whereby human-centred assumptions, emotional narratives, or cultural norms influence interpretations of welfare, sentience, or sustainability. Such projections can undermine scientific objectivity, misrepresent species-specific needs, and weaken the frameworks’ applicability in research, policy, and practice. This paper critically examines how anthropomorphising concepts may arise within this context, distinguishing empirically supported biological continuity from unwarranted human-like attributions. It highlights the importance of precise language, operational definitions, and comparative evidence to safeguard conceptual integrity. While both frameworks are fundamentally non-anthropomorphic, careless language and human-centred assumptions can compromise their scientific rigour and ethical coherence. Avoiding conceptual anthropomorphisation is therefore essential to maximise their value for robust welfare assessment, policy development, and sustainable practice. Full article
