Background: Functional Neurological Disorder (FND) encompasses conditions with neurological symptoms inconsistent with structural pathology, arising instead from complex interactions between psychological, biological, and social factors. Despite growing research, the etiological and risk factor landscape remains only partially understood, complicating diagnosis and treatment. Objective: This systematic review maps risk factors for major FND subtypes such as functional seizures (psychogenic non-epileptic seizures or PNES), functional cognitive disorder (FCD), functional movement disorders (FMD), functional weakness and sensory disturbances, functional visual symptoms, and functional gait abnormalities by categorizing predisposing, precipitating, and perpetuating influences. Methods: A systematic search of PubMed, PsycINFO, Scopus, and Web of Science initially identified 245 records. After removal of 64 duplicates, 181 studies were screened by title and abstract. Of these, 96 full texts were examined in detail, and finally 23 studies met the predefined inclusion criteria. Data were extracted and analyzed thematically within a biopsychosocial framework, with results summarized in subtype-specific profiles. Results: Childhood adversity, especially emotional, physical, or sexual abuse, emerged as a robust and consistent predisposing factor across PNES cohorts. Psychiatric history (notably anxiety, depression, and PTSD), neurodevelopmental traits (more frequent in FCD), and personality patterns such as alexithymia and somatization also contributed to vulnerability. Precipitating influences included acute psychological stress, intrapersonal conflict, or concurrent medical illness. Perpetuating factors comprise maladaptive illness beliefs, avoidance behaviors, insufficient explanation or validation by healthcare providers, and secondary gains related to disability. While several risk factors were shared across subtypes, others appeared subtype-specific (trauma was especially associated with PNES, whereas neurodevelopmental traits were more characteristic of FCD). Conclusions: FND arises from a dynamic interplay of predisposing, precipitating, and perpetuating factors, with both shared and subtype-specific influences. Recognizing this heterogeneity can enhance diagnostic precision, guide tailored intervention, and inform future research into the neurobiological and psychosocial mechanisms underlying FND.

Visual information is crucial in human life, not only providing critical support for communication, learning, and decision-making, but also playing a key role in psychology, medicine, and science. Eye-tracking and gaze estimation have promoted the development of foveated rendering in wearable virtual reality and augmented reality glasses. This review summarizes the recent development on gaze estimation and discusses the impacts of head posture, illumination, occlusion, blur, and individual bias on the accuracy of eye-tracking. The prospective development on eye-tracking employing unsupervised learning, self-supervised learning, and meta-learning have also been discussed. Full article

Background/Objectives—The personalisation agenda—matching the correct psychological therapy to diverse and comorbid mental disorders—is an unanswered dilemma in the worldwide literature which has far reaching consequences for public health. This hypothesis article addresses the question: can a biomedical approach resolve the personalisation agenda? Methods—Narrative review drawing on clinical psychology, translational psychiatry, and biomedical science literature. Results—Diverse attempts to resolve the personalisation agenda have not yet succeeded. Randomised controlled trials are uniquely biased due to unwanted placebo effects; network meta-analysis cannot address adequately which psychological therapy to use; new methodologies have not yet produced data; and neuroscientific analysis cannot yet explain how trauma-based therapies work. However, a biomedical model which divides psychological therapy into low, medium and high intensity interventions can resolve the personalisation agenda. Conclusions—Combining low intensity (placebo), with medium intensity (cognitive behavioural techniques) and high intensity interventions (trauma-based therapies) are theoretically synergistic if combined with psychosocial treatments/exercise, and used in sequence in the correct order. A biomedical model based on recent advances in placebo studies and neuroplasticity can resolve the personalisation agenda, and improve outcomes for mental disorder. Full article

Introduction: Negative behaviors in nursing undermine well-being, erode team cohesion, and jeopardize patient safety. Rooted in systemic stressors—workload, emotional strain, and power imbalances—they have far-reaching effects on job satisfaction and care quality. Objective: To systematically map the scientific evidence on negative behaviors among nurses in healthcare organizations. Methods: A scoping review was conducted using five databases: CINAHL, MEDLINE, Scopus, Psychology & Behavioral Sciences Collection, and RCAAP (for grey literature). The review followed the Joanna Briggs Institute methodology and PRISMA-ScR reporting guidelines. Two independent reviewers conducted data extraction and synthesis. Results: Eighteen studies published between 2017 and 2024 met inclusion criteria from an initial pool of 88 references. Eleven thematic domains emerged: (1) the cycle of violence; (2) victims profile; (3) perpetrator profile; (4) negative behaviors spectrum; (5) negative behaviors prevalence; (6) risk predictors; (7) protective predictors; (8) impact of negative behaviors on nurses; (9) impact of negative behaviors on patients; (10) impact of negative behaviors on healthcare organizations; (11) organizational strategies and the role of the nurse managers. Conclusions: The findings highlight the multidimensional nature of negative behaviors and the variability in how they are defined and assessed. This review highlights the need for conceptual clarity and standardized tools to address negative behaviors in nursing. Nurse managers, as key organizational agents, play a critical role in fostering psychological safety, promoting ethical leadership, and ensuring accountability. System-level strategies that align leadership with organizational values are essential to protect workforce well-being and safeguard patient care. Full article

Guide dogs are primarily seen as mobility aids for people with visual impairments, but they may also influence users’ psychological well-being and social lives. Benefits of being partnered with a guide dog have been found in several countries but Scandinavian studies are sparse. This qualitative study explores the lived experiences of six Danish guide dog partners through semi-structured interviews. A reflexive thematic analysis found six primary benefits: improved mobility, increased physical activity, enhanced freedom and independence, new social interactions, a strong emotional bond with the dog, and better mental well-being. Users also reported challenges, including frequent distractions caused by the public interacting with the dog, difficulties during the initial adjustment period, increased cleaning, and occasional trouble finding care for the dog. Participants unanimously emphasized the irreplaceable value of their guide dogs and positive socioemotional dimensions of guide dog partnerships. The findings add Scandinavian voices that support existing international research and note three areas of potential improvement: better public education about guide dog etiquette, enhanced support during the adjustment period, and improved care-sharing arrangements. The study underscores the importance of considering guide dogs as both functional aids and sources of emotional and social support. Full article

While increasingly popular for their aesthetic appeal and energy efficiency, reflective materials may also create harsh glare, disorientation, and psychological strain. Despite their prevalence in modern architectural design, the impact of these facades on mental well-being remains underexplored. Drawing from environmental psychology and perceptual science, this study assesses how different reflective materials influence both visual perception and psychological response, particularly among residents and students in Leicester. Two contrasting case studies, the reflective metal Highcross centre facade and the reflective glass Mattioli Woods PLC facade, served as focal points. Using a structured online questionnaire incorporating visual stimuli and Likert-scale questions, responses from 30 participants were analysed using descriptive and statistical analysis (i.e., one-way ANOVA) to determine differences in visual discomfort (due to brightness, glare, or shine), visual attractiveness, visual disorientation, and perception of the surroundings, as well as the associated physiological responses such as stress, tension, and mood. Results show that the Highcross Centre facade was consistently perceived as more visually discomforting and disorienting than the Mattioli Woods facade, with statistically significant differences. However, both facades were rated similarly high for visual interest, suggesting that aesthetic value can coexist with discomfort. Finally, the analysis shows that buildings’ reflective facades evoke only low levels of perceived stress, tension, or unease, with median scores remaining low overall. These findings highlight the importance of human-centred facade design, suggesting that, as cities adapt to climate change, architects and urban planners consider not only environmental performance but also perceptual and psychological effects.

The shortage of math and science teachers is a pressing issue in the United States (US) and globally. This review closely follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and synthesizes findings from 43 peer-reviewed empirical studies published between 2005 and 2024 on the recruitment and retention of math and science teachers, offering a new perspective for understanding and mitigating math and science teacher shortages. This review revealed (a) the qualifications and characteristics of math and science teachers who enter and remain in the teaching profession; (b) that financial incentives, experiential learning, mentorship, and professional development are commonly used strategies and mechanisms to recruit and retain math and science teachers; and (c) that psychological, sociocultural, and working conditions are factors that influence math and science teachers’ decisions to enter and remain in the teaching field. While this review primarily focuses on the US context, it offers valuable insights for researchers, practitioners, policymakers, and other key stakeholders worldwide by identifying strategies, mechanisms, and factors that shape teacher recruitment and retention in math and science. This review also discusses gaps in the literature, directions for future research, and implications for research, policy, and practice that emerge from the empirical evidence. Full article

Background: This systematic review aims to summarize the most recent data from the literature on the psychological aspects of parents of children prenatally diagnosed with congenital heart defects (CHDs). Methods: A comprehensive literature search was conducted to identify relevant studies on the psychological issues faced by parents of children prenatally diagnosed with CHD. Searches were performed in multiple scientific databases, including PubMed, Science direct, Embase, Scopus, Medline, Clarivate, to ensure the broad coverage of the literature. The search was limited to studies published up until February 2025. The search strategy included the following terms and combinations: “congenital heart defect” OR “CHD” AND “prenatal diagnosis” AND “psychological impact” OR “parental distress” OR “coping”. Results: Eighteen studies involving the 673 parents of fetuses diagnosed with congenital heart defects were included. Studies spanned four continents and employed both qualitative (n = 14) and quantitative (n = 4) designs. Key psychological outcomes reported were anxiety, depression, stress, post-traumatic stress, coping strategies, maternal–fetal attachment, and life satisfaction. Anxiety and depression were the most frequent issues, with maternal anxiety reaching 65% and depression up to 45.7%. Stress related to diagnostic uncertainty was common. While some parents used adaptive coping (social support, emotional regulation), others experienced maladaptive patterns such as avoidance. One study reported increased maternal–fetal attachment following prenatal CHD diagnosis. Predictors of psychological distress included time of diagnosis, parental gender, education level, social support, and severity of the defect. Recommended interventions included early psychological screening, empathetic communication, structured counseling, and long-term emotional support. Despite heterogeneity in design and moderate overall bias, findings highlight a consistent psychological burden among parents, underscoring the need for integrated psychosocial care following a prenatal CHD diagnosis. Conclusions: Parents whose children have been prenatally diagnosed with a congenital heart defect are at an increased risk for psychological distress. To improve the quality of care, a multidisciplinary team is needed to provide parents with the necessary information on diagnosis, interventions, and potential outcomes. Full article

This essay examines emotions as a critical, yet underutilized, dimension in marine conservation and ocean sustainability science. Drawing on cognitive neuroscience, social psychology, human geography, and political ecology, we argue that integrating emotional dimensions into research, policy, and practice can enhance both understanding and action toward marine conservation and ocean sustainability. We conceptualize emotions, and explore their experiential and functional implications in marine contexts. Using targeted case examples and theories, we identify both opportunities and challenges for applying emotional insights in research, policy, and practice, including barriers posed by dominant rationality models of human decision-making. We present intellectual pathways as well as research, methodological and policy agendas to integrate emotions into marine conservation research and strategies. Our analysis responds to gaps in the literature and provides actionable recommendations for researchers, policymakers, and practitioners during the UN Decade of Ocean Science for Sustainable Development.

Background: Depression is a significant global mental health concern, especially among medical students. This study combines two components: (1) a cross-sectional assessment of depression and related psychological and demographic factors among students at “Dunărea de Jos” University of Galați, and (2) a systematic review and meta-analysis of published Romanian studies on depression in medical students. Methods: For the cross-sectional component, 495 students (Years I–III) completed online questionnaires assessing depressive symptoms (PHQ-9), personality traits, procrastination, and sociodemographic factors. In the systematic review, studies from PubMed and Web of Science were synthesized following PRISMA guidelines, with prevalence data being pooled via random-effects meta-analysis. Results: In the Galați sample, 34.0% of students had clinically significant depressive symptoms (PHQ-9 ≥ 10). Depression was associated with female gender, being in the third year of study, low social support, high neuroticism, and procrastination. The meta-analysis (six studies, N = 1546) yielded a pooled national prevalence of 19.99% (95% CI: 18.24–21.73%). Conclusions: Depression is highly prevalent among Romanian medical students, particularly in Galați. The findings support the need for targeted mental health interventions in Romanian universities. Registration: This systematic review has been registered in the Prospero database (registration number CRD420251056873). Full article

Fatigue in elite soccer is a multifaceted phenomenon involving physical, metabolic, psychological, and neuromuscular stressors that accumulate over training and competition. Traditional monitoring tools, while informative, are often invasive, impractical during play, or fail to provide real-time insights. This narrative review synthesizes sweat-based biomarkers linked to fatigue in elite soccer, with a focus on multi-modal domains (neuromuscular, metabolic, inflammatory, psychological). Using an integrative approach, we reviewed studies published across databases including PubMed, Scopus, and Web of Science that evaluate sweat biomarkers of different types of fatigue in soccer. We identified key candidates—lactate, sodium, cortisol, IL-6, and hypoxanthine—and evaluated their potential in non-invasive monitoring. Youth-specific and female populations remain underrepresented. We also assessed each biomarker’s technological maturity using a sweat-specific Technology Readiness Level (TRL) framework. Based on these findings, we propose a translational framework for practitioners and outline priorities for future research and validation in real-world sport settings. Full article

Background/Objectives: Academic stress arises when students perceive that university demands exceed their coping resources, leading to cognitive, behavioral, and physiological stress responses. This study examines the predictive role of academic stressors and sociodemographic variables across five dimensions of stress response. Methods: The sample comprised 1014 Spanish university students (64.5% women, 35.5% men; M = 20.56, SD = 3.50). Participants completed the Academic Stressors Scale (E-CEA) and the Stress Responses Scale (R-CEA). Hierarchical regression analyses were conducted in two blocks: sociodemographic variables were entered in the first block, followed by academic stressors in the second. Results: Academic stressors accounted for substantial variance in all five stress response dimensions: negative thoughts (47.8%), physical exhaustion (39.5%), physical agitation (32.9%), irritability (29.7%), and sleep disturbances (26.8%). The most recurrent predictors were beliefs about performance, exams, and academic overload. In contrast, sociodemographic variables explained a much smaller portion of the variance (5.9%) and were specifically linked to higher irritability among women and younger students, more negative thoughts among students in Arts and Humanities, and fewer physical symptoms and sleep disturbances in students from science and technical fields. Conclusions: The findings reveal that academic stressors are key contributors to psychological distress among university students, highlighting the need for institutional interventions to alleviate the most frequent stressors. Identifying student groups particularly vulnerable to academic stress further supports the implementation of tailored strategies that address the diversity of students’ profiles and needs.

Background/Objectives: Chemotherapy is an aggressive form of oncological treatment often accompanied by numerous adverse effects. A patient’s baseline status significantly influences the course of therapy, its efficacy, quality of life, and overall survival. This review aims to analyze the published peer-reviewed studies in this area and to assess whether they permit the formulation of preliminary recommendations for future prehabilitation protocols. Methods: An integrative review was conducted due to the limited number of relevant studies. Four databases—MEDLINE/PubMed (Medical Literature Analysis and Retrieval System Online/National Library of Medicine), Scopus, Cochrane, and Web of Science—were systematically searched for English-language articles published between 2010 and 13 January 2025, using the terms “prehabilitation,” “chemotherapy,” “drug therapy,” and “neoadjuvant.” A total of 162 records were retrieved. After duplicate removal, titles and abstracts were screened. The remaining papers were subjected to detailed analysis, resulting in ten studies with diverse methodologies being included. Results: We reviewed ten (n = 10) studies, most of which were reviews focused on breast cancer, indicating variation in the state of knowledge across different cancer types. A protein intake of 1.4 g/kg body mass helps preserve fat-free mass, with whey being more effective than casein. Omega-3 fatty acid supplementation at a dose of 2.2 g/kg may prevent chemotherapy-related neurotoxicity and support appetite and weight maintenance. Physical activity, especially when it includes strength training, improves VO₂max, preserves fat-free mass, and may reduce stress and anxiety. We identified one randomized controlled trial in which a single exercise session before the first dose of doxorubicin resulted in a smaller reduction in cardiac function. Continuous psychological support should be available. A combined behavioural and pharmacological approach appears to be the most effective strategy for smoking cessation. Conclusions: No official guidelines exist for prehabilitation before chemotherapy, and the availability of studies on this topic is very limited. The pre-treatment period represents a critical window for interventions. Further research is needed to evaluate the effectiveness and applicability of particularly single-component interventions.

(1) Background: Domestic violence (DV), including intimate partner violence (IPV) during pregnancy and the puerperium, represents a major public health issue, significantly affecting maternal and child health. (2) Methods: This systematic review and meta-analysis, conducted according to PRISMA 2020 guidelines, aimed to identify screening tools used to detect DV and IPV among pregnant and postpartum women and to estimate DV prevalence. The protocol was published in PROSPERO in advance (CRD42023473392). (3) Results: A comprehensive literature search across PubMed, EMBASE, Scopus, and Web of Science was conducted on 1 January 2024, resulting in 34,720 records; 98 studies met the inclusion criteria. The included studies were conducted in over 40 countries, and most were cross-sectional. Commonly used screening tools included the WHO Women’s Health and Life Experiences Questionnaire, the Abuse Assessment Screen, and the WHO Violence Against Women Instrument. Meta-analyses showed that 10% of women experienced physical violence, 26% psychological violence, 9% sexual violence, 16% verbal violence, and 13% economic violence. The overall prevalence of IPV during pregnancy and the puerperium was 26%. Despite the widespread use of validated instruments, substantial heterogeneity was observed, underscoring the need for standardization. (4) Conclusion: These findings underline the urgent need to integrate routine IPV screening into maternal care pathways using validated, culturally adapted tools, ensuring women’s safety and confidentiality.

The latent class model has been proposed as a powerful tool in understanding human behavior for various fields such as social, psychological, behavioral, and biological sciences. However, one important limitation of the latent class model is that it is primarily applied to data with binary responses or categorical responses, making it fail to model real-world data with continuous or negative responses. In many applications, ignoring the weights throws out a lot of potentially valuable information contained in the weights. To address this limitation, we propose a novel generative model, the arbitrary-distribution latent class model (adLCM). Our model enables the generation of data’s response matrix from an arbitrary distribution with a latent class structure. When compared to the latent class model, our adLCM is both more realistic and general. To our knowledge, our adLCM is the first model for latent class analysis with any real-valued responses, including continuous, negative, and signed values, thereby extending the classical latent class model beyond its traditional limitation to binary or categorical outcomes. We investigate the identifiability of the model and propose an efficient algorithm for estimating the latent classes and other model parameters. We show that the proposed algorithm enjoys consistent estimation. The performance of our algorithm is evaluated using both computer-generated data and real-world personality test data. Full article
