Objectives: Existing animal models of post-traumatic stress disorder (PTSD) are often methodologically complex and produce variable outcomes. The aim of this study was to develop a modified PTSD model that accurately recapitulates the clinical progression of the disorder, incorporating both behavioral features and objective physiological parameters. Methods: We utilized a modified Single Prolonged Stress with Subsequent Stress (SPS&S) protocol, supplemented by a stress reminder phase (without re-exposure to primary stressors) and an evaluation of stress response extinction. Eighty male Wistar rats were subjected to the stress protocol, followed by comprehensive behavioral, hematological (leukocytes, hemoglobin, and hematocrit), and hormonal (corticosterone; adrenocorticotropic hormone (ACTH)) assessments 4–5 weeks post-stress. Results: The model produced a PTSD-like phenotype in 25% of animals, characterized by persistent alterations in the investigated biomarkers. The PTSD group exhibited sustained behavioral impairments (increased anxiety), hematological changes (neutrophilic leukocytosis), and endocrine dysregulation (decreased corticosterone, ACTH, and epinephrine). Conclusions: This modified SPS&S model demonstrates validity for studying the long-term consequences of stress, with PTSD markers remaining stable throughout the 28-day observation period.

Inclusive AI-mediated mathematics education for students with learning difficulties refers to a human-centered approach to mathematics teaching and learning that uses artificial intelligence (AI), adaptive technologies, and data-rich environments to support learners who experience persistent challenges in mathematics. These challenges may take the form of a formally identified developmental learning disorder with impairment in mathematics, broader learning difficulties, low and unstable achievement, irregular engagement, or heightened mathematics anxiety that places students at risk of disengagement and poor long-term outcomes. This approach integrates early screening, personalized instruction, and affect-aware support to address both cognitive difficulties and the emotional burden associated with mathematics anxiety. Situated within digitally augmented schools, homes, and community spaces typical of smart cities, it seeks to reduce stress and anxiety, prevent the reproduction of educational inequalities, and promote equitable participation in science, technology, engineering, and mathematics (STEM) pathways. It emphasizes Universal Design for Learning (UDL), ethical and transparent use of learner data, and sustained collaboration among teachers, families, technologists, urban planners, and policy-makers across micro (individual), meso (school and community), and macro (urban and policy) levels. Crucially, AI functions as decision support rather than replacement of pedagogical judgment, with teachers maintaining human-in-the-loop oversight and responsibility for inclusive instructional decisions. Where learner data include fine-grained logs or affect-related indicators, data minimization, clear purpose limitation, and child- and family-friendly transparency are essential. Implementation should also consider feasibility and sustainability, including staff capacity and resource constraints, so that inclusive benefits do not depend on high-cost infrastructures.

5a-reductase (5a-R) isozymes are essential for androgen metabolism and neurosteroid biosynthesis, linking endocrinology and neuropsychiatry. This systematic review, conducted in accordance with PRISMA 2020 guidelines, aimed to synthesize current evidence on the tissue distribution of SRD5A1, SRD5A2, and SRD5A3 and their implications in mental health. A systematic search of the PubMed, Scopus, and Web of Science databases up to February 2025 identified 257 articles, of which 83 met the inclusion criteria. SRD5A1 is broadly expressed in the liver, skin, and central nervous system, contributing to allopregnanolone synthesis; SRD5A2 is mainly restricted to androgen-dependent tissues, playing a key role in prostate development and alopecia; and SRD5A3 is associated with glycosylation processes and oncogenesis. Converging evidence suggests that impaired neurosteroidogenesis due to 5α-R inhibition may underlie vulnerability to anxiety, depression, and suicidality. While earlier epidemiological findings were heterogeneous, recent pharmacovigilance data have strengthened the evidence supporting this association. Pharmacovigilance and clinical reports show that a subset of patients treated with finasteride or dutasteride may experience persistent psychiatric and sexual adverse effects, known as post-finasteride syndrome. The current findings underscore the need for careful patient counseling, systematic monitoring, and further translational studies integrating genetics, neuroendocrine markers, and standardized psychiatric outcomes to identify individuals at risk and advance personalized medicine in this field.

Background: Postpartum depression and anxiety are common in the perinatal period and can adversely affect maternal functioning and infant outcomes. Self-esteem is a relevant psychosocial factor, yet evidence from Eastern Europe remains limited. Objectives: To describe self-esteem levels among postpartum Romanian women, examine correlational associations between self-esteem and postpartum depression/anxiety symptoms, and assess whether these associations persist after adjustment for sociodemographic and clinical covariates, across two maternity centers in a cross-sectional design. Methods: This cross-sectional study included 201 postpartum women recruited consecutively during their initial postpartum hospitalization from two public maternity hospitals in Western Romania (Bihor, n = 100; Timiș, n = 101) during 2024–2025. Participants completed the Rosenberg Self-Esteem Scale (RSES), Edinburgh Postnatal Depression Scale (EPDS), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7). Associations were assessed with χ² tests (categorical comparisons), Pearson correlations, and multivariable linear regression models including center and selected sociodemographic/obstetric covariates. Results: Self-esteem showed a strong inverse correlation with postpartum depressive symptoms (RSES–EPDS: r = −0.542 overall; r = −0.537 in Bihor; r = −0.552 in Timiș; all p < 0.001). Negative correlations were also observed with anxiety (RSES–GAD-7: r = −0.400; p < 0.001) and PHQ-9 depressive severity (r = −0.370; p < 0.001). Stratified analyses indicated graded symptom burden across self-esteem categories, with higher EPDS risk proportions among women with moderate/low self-esteem within each center (χ²p ≤ 0.039). In adjusted models, EPDS (B = −0.37; p < 0.001) and GAD-7 (B = −0.15; p = 0.021) remained independently associated with lower RSES, alongside study center (Timiș vs. Bihor: B = −1.08; p = 0.043) and educational attainment. Conclusions: Lower self-esteem co-occurs with postpartum depressive symptoms and, secondarily, anxiety in Romanian women. While the cross-sectional design precludes causal inference, these robust correlational associations support the potential value of self-esteem assessment for early psychosocial risk identification. Longitudinal research is needed to establish temporal relationships and evaluate whether self-esteem can prospectively predict postpartum mental health outcomes. Full article

Background: Patellofemoral pain (PFP) is a prevalent overuse injury among recreational cyclists worldwide. Despite its ubiquity, little is known about the lived experiences of people with PFP, especially in Saudi Arabia, where healthcare and cultural factors may have a specific impact on how the condition is managed. The aim of this study was to explore the lived experiences of recreational cyclists with patellofemoral pain in Al Madinah, Saudi Arabia. Method: A qualitative, descriptive design using reflexive thematic analysis was employed. Eleven male recreational cyclists aged 28–44 years diagnosed with PFP were purposely recruited from Al Madinah Physical Therapy Centre. Female participants were excluded due to cultural constraints regarding sports participation. The participants consented to participate in the study and to be audio recorded. Data were collected through semi-structured interviews using an interview guide. The interview data were transcribed verbatim and thematically analysed using Atlas.ti, version 24. Results: The thematic analysis revealed six themes highlighting the multidimensional impact of PFP. The participants described localised mechanical impairment with rapid onset during activity and persistent symptoms lasting up to two weeks. Pain was exacerbated by eccentric loading and cycling-specific stressors, such as uphill riding, leading to significant anxiety and avoidance behaviours. To maintain activity, these cyclists employed adaptive strategies, including bike modifications and self-management. Notably, PFP imposed substantial cultural and social burdens, hindering spiritual practices, specifically Salah (prayer) postures, professional duties, and family caregiving. While the participants demonstrated resourcefulness through a hybrid of physiotherapy and independent research, pharmacological relief was viewed as a transient solution. Conclusions: Patellofemoral pain imposes significant multidimensional burdens on recreational cyclists in Al Madinah, which are exacerbated by cultural practices. Physiotherapy offers targeted interventions for pain relief, functional restoration, and participation enhancement, necessitating the need for culturally sensitive management programmes.

Children’s responses to the climate crisis range from mistrust and helplessness to activism and eco-anxiety, highlighting the need for early educational experiences that foster constructive engagement. At the same time, the persistent underrepresentation of women in science highlights the importance of integrating gender awareness into science education. While hands-on activities and storytelling are widely recognized as effective educational strategies, less attention has been given to how these approaches can be meaningfully combined within a single learning experience. This exploratory study investigates the integration of hands-on environmental science activities and theatrical storytelling as an interdisciplinary, gender-aware educational design for children aged 6 to 11. The intervention included clean energy and greenhouse effect experiments guided by two actresses portraying pioneering scientists, Eunice Newton Foote and Susan Solomon, situating scientific concepts within narrative, historical, and social contexts. Qualitative observations and an exploratory analysis of children’s drawings indicate that narrative and embodied approaches can support cognitive and emotional engagement while fostering more inclusive representations of scientific practice. The study proposes a preliminary, interdisciplinary approach of engagement and inclusion, providing a starting point for future research on integrated, gender-aware environmental education.

Background: Perinatal depression and anxiety are common but often under-detected. Current screening relies on depression-centered instruments and may miss relational drivers including sexual dysfunction, low self-esteem, and psychosocial adversity. Objective: To synthesize evidence on sexual function, self-esteem/body image, and psychosocial context as correlates of perinatal depression and anxiety, and propose a risk-stratified screening framework. Methods: We conducted a narrative evidence synthesis of studies from January 2010 to May 2025 (PubMed/MEDLINE, Scopus, Web of Science) examining associations between perinatal mood/anxiety outcomes and sexual function (Female Sexual Function Index), self-esteem/body image (Rosenberg Self-Esteem Scale), and psychosocial factors (perceived support, intimate partner violence). Results: Sexual dysfunction was highly prevalent and consistently associated with depressive and anxiety symptoms. Longitudinal evidence demonstrated bidirectional pathways: mood symptoms reduced sexual satisfaction, while sexual difficulties intensified relational strain and symptom persistence. Low self-esteem and negative body image mediated links between physiological changes and postpartum depression. Psychosocial adversity, particularly low partner support and intimate partner violence, identified high-risk subgroups with greater severity and slower recovery. Single-instrument approaches (Edinburgh Postnatal Depression Scale alone) may miss pregnancy-specific anxiety and postpartum relational drivers. Conclusions: A staged, risk-stratified model is recommended: assess pregnancy-specific anxiety alongside depression screening in the second/third trimesters; postpartum, selectively add sexual function and self-esteem assessment for women with elevated symptoms or psychosocial risk. Integration within defined referral pathways may improve detection and enable targeted perinatal mental health care. Full article

Sport persistence is a key factor in maintaining a sporting career and preventing dropout from sport. Among psychological and social factors, social support plays a prominent role as a protective factor that strengthens self-esteem and reduces the risk of burnout, as does the perfectionist climate, which is motivating in a supportive environment but places psychological burdens on athletes in its maladaptive forms. The research aimed to explore the extent to which the sport persistence of young athletes can be explained by different sources of social support (parental, teacher, peer) and the dimensions of the perfectionist climate (expectations, criticism, control, conditional respect, anxiety), as well as the role played by gender. We conducted a cross-sectional, quantitative study involving 1105 young people aged 14–25 who regularly participate in sports. We used validated questionnaires to measure sports persistence, social support and perfectionist climate. We used regression and mediation models to analyse the data. According to the analyses, parental and teacher support contributed to increased sport persistence, while peer support had no significant effect. Among the dimensions of the perfectionist climate, expectations were positively related to persistence, while criticism was negatively related. Gender also indirectly influenced sports persistence, with its effect partly mediated by social support and the perfectionist climate. The results indicate that parental and teacher support, along with an emphasis on healthy expectations, are vital for strengthening sports persistence. In contrast, a critical, controlling climate was associated with lower persistence among female athletes in the present sample. Full article

Obesity is associated with profound metabolic, inflammatory, and neurobehavioral dysfunctions. Dietary interventions leading to weight loss are commonly employed, yet it remains unclear whether all obesity-related alterations are fully reversed upon reaching normal body weight. Poor adherence to dietary regimens often results in weight cycling, or yo-yo dieting, characterized by repeated episodes of weight gain and loss, a phenomenon linked to adverse health outcomes. Here, we investigated the consequences of weight cycling in C57BL/6J mice. The Control Group was maintained on a standard chow diet throughout the protocol, whereas the experimental group underwent two alternating cycles of high-fat diet feeding (weight gain) and standard diet reversion (weight loss), until the end of the protocol where both groups reached 80 weeks of age. Despite achieving a final body weight and glucose and lipid metabolic profile comparable to lean controls, weight-cycled mice exhibited impaired sensorimotor function, increased anxiety-like behavior (evaluated through behavioral tests), and persistent inflammation, including a peritoneal macrophage pro-inflammatory profile and adipose tissue infiltration. We define this phenomenon as “obesogenic inflammatory memory”, highlighting that obesity leaves an immunological imprint that sustains inflammation even after normalization of weight and metabolic parameters. These findings demonstrate that weight cycling is associated with chronic macrophage-mediated inflammatory states, linked to long-term behavioral and neurological manifestations, and opening new avenues for future investigation and therapeutic approaches.

Background/Objectives: Multiple sclerosis (MS) is a chronic neurological disease characterized by demyelination, inflammation, and autoimmunity, leading to progressive physical and psychological impairments. Anxiety and depression are among the most prevalent neuropsychiatric comorbidities in MS, significantly impacting patients’ quality of life (QoL). This study aimed to assess the evolution of anxiety and depression in individuals with relapsing-remitting multiple sclerosis (RRMS) over a six-month follow-up period, identify associated factors, and explore potential predictors of these psychological conditions. Methods: A prospective observational study was conducted with 35 RRMS patients diagnosed at the Lucus Augusti University Hospital between January 2023 and March 2025. Psychological symptoms were assessed at baseline, after 3 months, and after 6 months using the Goldberg Anxiety and Depression Scale (GADS), the Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI). Data were analyzed using non-parametric tests to account for the small sample size and non-normal distribution of variables. Results: Anxiety and depression were prevalent and persistent in the study population, with no significant changes in mean scores over time (p > 0.05). However, specific symptoms, such as pessimism and loss of pleasure, showed worsening trends, while sadness and guilt remained stable. Sociodemographic factors, including lower income and employment status, were significantly associated with higher anxiety and depression scores (p < 0.05). Additionally, clinical factors such as autoimmune comorbidities and a history of mononucleosis were linked to higher depressive symptoms. Baseline anxiety and depression scores emerged as strong predictors of future levels (p < 0.01), emphasizing the importance of early assessments. Conclusions: Anxiety and depression are prevalent and persistent in RRMS patients, with specific symptoms fluctuating over time. Sociodemographic and clinical factors play a significant role in psychological outcomes, highlighting the need for integrated care models that address both physical and psychosocial aspects of MS. Early psychological assessments and targeted interventions are critical for improving QoL and mitigating the long-term burden of mental health challenges in RRMS. Full article

Electric vehicles (EVs) are central to low-carbon urban mobility, but range anxiety persists. In real fleet operations, vehicles are rarely discharged to low State-of-Charge (SOC), so the remaining driving range (RDR) labels are incomplete, hindering accurate RDR prediction and analysis of operating conditions. This paper proposes a label completion framework that reconstructs low SOC mileage and a hybrid mileage-factor-oriented residual regressor (MF-CMR) to learn mileage factors under SOC imbalance. Applied to one year of data from eight EVs in Guangzhou, China, the method achieves a mean absolute error of 0.88 and a coefficient of determination of 0.64, yielding completed trip-level RDR labels whose distribution centers around 241.73 km. Using the completed labels, a two-way analysis of variance (ANOVA) with ambient temperature and driving style as factors shows that temperature is the dominant determinant of RDR, while driving style exerts a secondary but substantial effect, with a significant interaction. Together, the label completion framework and the quantified impacts of temperature and driving style enable more reliable RDR estimation from fleet logs, offering a quantitative basis for dispatching policies, charging margins, and eco-driving guidance in EV fleet services involving long distance trips or low SOC deep discharge scenarios.

Background/Objectives: Von Hippel–Lindau (VHL) disease is a rare autosomal dominant hereditary disorder. Central nervous system hemangioblastomas are one of the most common tumor types associated with VHL disease. Although these tumors are histologically benign, delayed diagnosis and treatment may result in severe neurological dysfunction, permanent disability, and even death. However, little is known about the experiences of patients with VHL disease. The aim of this study was to gain a better understanding of the illness experiences and psychological responses of patients with VHL disease accompanied by central nervous system hemangioblastomas. Methods: A qualitative study based on a semi-structured guide was conducted. Twelve participants were recruited. Data were collected through face-to-face interviews and analyzed using the constant comparative method. Results: Four themes and their subthemes were identified: 1. powerlessness—unpredictable disease progression and uncontrollable continuity; 2. negative emotional experiences—guilt and self-blame, depression, and low self-esteem; 3. compromise—acceptance of fate, positive outlook, and sense of hope; and 4. persistent worry—worries about family members, anxiety regarding finances and employment, and uncertainty regarding the future. Conclusions: This study identified four major themes in the illness experiences of patients with VHL disease accompanied by central nervous system hemangioblastomas, which provided deep insights into the care needs of individuals with VHL disease. Healthcare providers should develop effective measures to enhance patients’ ability to maintain a good quality of life and confront the future with resilience. Full article

Shelter environments frequently expose dogs to chronic stress and anxiety, which can compromise their welfare and reduce their chances of adoption. Recent interest in psychedelic-assisted approaches has suggested potential therapeutic applications in veterinary behavioral medicine, although empirical evidence remains scarce. This study aimed to evaluate the combined effects of low-dose 1-cyclopropionyl lysergic acid diethylamide (1cp-LSD), a legal lysergamide prodrug of LSD in several countries, and ethological intervention (EI) on the behavior and welfare of shelter dogs. Twenty dogs were randomly assigned to four groups: pharmacological intervention, ethological intervention, combined treatment, or control. The ethological sessions were conducted by veterinary behaviorists, and pharmacological treatment consisted of 10 µg of 1cp-LSD administered orally for three weeks. Blinded evaluators assessed animals using validated anxiety and welfare scales, including a treatment expectation scale, before, during and after the intervention. Results showed that the combined condition consistently outperformed single interventions, significantly enhancing sociability, calmness, and positive emotional reactivity. Importantly, these improvements persisted for three weeks following treatment cessation, indicating sustained benefits beyond the active intervention phase. These findings provide preliminary evidence for the potential of integrating low doses of psychedelics with behavioral therapy in shelter settings. Future studies with larger cohorts and refined pharmacokinetic data are required to confirm safety, elucidate mechanisms, and optimize protocols for clinical application in veterinary practice.

Background: Functional dizziness and persistent postural-perceptual dizziness (PPPD) involve mutually reinforcing vestibular symptoms and anxiety. Non-pharmacological interventions, such as vestibular rehabilitation therapy (VRT) and cognitive behavioral therapy (CBT), aim to address both mechanisms, yet their overall effectiveness remains unclear. Methods: We systematically examined randomized controlled trials (RCTs) published between 2000 and 2025 that evaluated VRT, CBT, or multimodal approaches for adults with functional or chronic dizziness (including PPPD and related functional dizziness constructs) accompanied by significant anxiety. Twelve RCTs (513 participants) met the criteria, involving individuals with PPPD, chronic subjective dizziness, chronic vestibular disorders with prominent anxiety, and residual dizziness after benign paroxysmal positional vertigo. Results: Conventional VRT delivered in clinic or as structured home-based programs produced small-to-moderate improvements in dizziness-related disability versus usual care. Combining VRT with CBT or psychologically informed components yielded larger and more consistent reductions in disability and maladaptive dizziness-related beliefs. CBT-based interventions reduced anxiety and dizziness-related distress compared with supportive controls. Emerging modalities, including virtual-reality-based VRT, non-invasive neuromodulation, and heart-rate-variability biofeedback, showed potential, although they were limited by small samples and methodological issues. Most trials had some risk-of-bias concerns and evidence certainty ranged from very low to moderate. Conclusions: Integrated multimodal rehabilitation shows promise, although larger, high-quality RCTs using standardized procedures and outcome measures are required. Full article

Background/Objectives: This umbrella review critically evaluates the available evidence on psychobiotics for depressive and anxiety symptoms, emphasizing methodological quality, consistency of findings, and persistent gaps in the literature. Methods: A comprehensive search was conducted across PubMed/MEDLINE, Scopus, Web of Science, SciELO, Cochrane, and EBSCO (May–June 2025) to identify systematic reviews with meta-analyses of randomized controlled trials examining probiotic, prebiotic, and synbiotic interventions in adults with depressive and/or anxiety symptoms or diagnoses. Two reviewers independently screened studies, extracted data, and evaluated methodological quality using AMSTAR-2. Additional bibliometric, conceptual, and psychometric features were mapped, including geographical origin, publication timeline, scale distribution, and citation-based connectivity. Results: Thirty systematic reviews and meta-analyses were included. Methodological quality was predominantly moderate, low, or critically low in 76.6% of reviews. Probiotic interventions demonstrated consistent benefits for MDD (SMD = −0.50 [95% CI: −0.58 to −0.42], p = 0.0001). However, findings for anxiety were markedly inconsistent, despite the modest improvements in specific subgroups (SMD = −0.19 [95% CI: −0.28 to −0.10]; p < 0.01). Prebiotics for MDD interventions showed limited positive results (SMD = −0.25 [95% CI: −0.47 to −0.03]; p = 0.03). For anxiety, the effects are inconclusive (SMD = −0.07 [95% CI: −0.30 to 0.10]; p = 0.18). Evidence for synbiotics was scarce. Citation-mapping revealed a fragmented and unevenly connected evidence base. Conclusions: The current evidence suggests that probiotics may confer beneficial effects on depressive and anxiety symptoms; however, the same cannot be said for prebiotics and synbiotics. Evidence for the efficacy of prebiotics and synbiotics to treat depression and anxiety is still insufficient or heterogeneous. Registration: CRD420251164884. Full article
