Background: The Semipalatinsk Nuclear Test Site (SNTS) represents a unique example of long-term population exposure to ionizing radiation. This study aimed to assess the health status of individuals from three generations permanently residing in territories affected by radioactive contamination resulting from nuclear weapons testing at the SNTS, based on the findings of a population screening examination. Materials and Methods: A cross-sectional screening study was conducted among 2802 adults aged 18 years and older. The exposed group consisted of residents of the Abay and Beskaragai districts of the Abay Region and their descendants (n = 1358). The control group included residents of Arshaly village in the Akmola Region with no history of radiation exposure (n = 1444). All participants underwent a structured questionnaire survey, clinical examination, biochemical and hematological testing, and assessment of thyroid function. Individual radiation doses were obtained from the State Scientific Automated Medical Registry of Persons Exposed to Radiation (SSAMR). Results: Arterial hypertension (p < 0.001), chronic ischemic heart disease (p < 0.001), thyroid disorders (p < 0.001), malignant neoplasms (p = 0.003), renal diseases, and respiratory diseases were significantly more prevalent in the exposed population than in the control group. Exposed individuals also demonstrated significantly higher levels of total cholesterol, triglycerides, and the triglyceride-glucose (TyG) index, indicating increased insulin resistance. After adjustments, the only outcome that retained a statistically significant association with radiation dose was thyroid disorders (adjusted OR per 10 mSv increase = 1.017; 95% CI: 1.009–1.025; p < 0.001). ROC analysis demonstrated a moderate discriminative ability of radiation dose with respect to arterial hypertension (AUC = 0.715), chronic ischemic heart disease (AUC = 0.735), and ischemic stroke (AUC = 0.711). Conclusions: The findings suggest long-term adverse health effects associated with radiation exposure among populations residing near the SNTS. Continued epidemiological surveillance and medical monitoring of exposed individuals and their descendants are warranted. Full article

Nanotechnology has become an important platform in the fields of gene therapy and genome editing, providing delivery strategies that address persistent therapeutic challenges by improving the precision, efficiency, and safety of genetic modifications. This review highlights the central role of nanomaterials in overcoming persistent barriers to genetic interventions, including inefficient delivery, instability of genetic cargo, and off-target effects. Specifically, we emphasize the combined use of nanomaterials with clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) systems, which can improve editing specificity and therapeutic efficacy. Beyond the classical CRISPR/Cas9 platform, this review also discusses next-generation modalities such as base editors, Cas13, prime editing, and the recently described Tandem Interspaced Guide RNA and TIGR-associated protein (TIGR-Tas) system, while considering their therapeutic potential and distinct delivery challenges. By using nanomaterials, the stability and intracellular delivery of genome-editing systems are improved, enabling more effective treatments for genetic disorders and acquired diseases such as cancer and infectious diseases. In addition, nanocarriers provide controlled release, protection from degradation, and better biocompatibility, thereby improving the safety and reliability of gene-editing therapies. Despite these advances, important translational challenges remain, including immunotoxicity, large-scale manufacturing, and regulatory integration. Overall, the continued convergence of nanotechnology and genome engineering may support the development of personalized medicine strategies that adapt genetic engineering tools for patient-specific applications.

The main purpose of this work is to critically review the literature on neurocognitive disorders (ND) diagnosis. A critical review was conducted in PubMed, Scopus, and EBSCO. Systematic reviews and meta-analyses focusing on ND diagnosis were included. The selected studies were critically analyzed and conceptually integrated to identify relevant dimensions for the diagnosis of ND. The review included 88 studies. Most studies focused on Alzheimer’s disease and mild cognitive impairment. The literature remained predominantly centred on isolated diagnostic domains, and important limitations were consistently identified, including methodological heterogeneity, lack of standardized thresholds, and reduced clinical applicability. Based on the identified conceptual and methodological limitations, a Multidimensional Model of Neurocognitive Disorders (MOND model) for ND diagnosis was proposed. The MOND model was developed as a multidimensional, multilevel, transdiagnostic model integrating biological, neurocognitive, neuropsychiatric, motor, functional, frailty, reserve-related, and socio-environmental dimensions. The model may contribute to research, symptom classification, severity characterization, prognosis, and personalized intervention planning across different ND trajectories. Future studies using the MOND model should focus on refining algorithms to estimate the risk of ND. Full article

Major Depressive Disorder (MDD) has a multifactorial etiology and pathogenesis that significantly impacts an individual’s quality of life. One of the possible correlations for its onset is the activation of inflammatory responses resulting in neurodegeneration and, consequently, the emergence of depressive symptoms. Interleukin-1β is a regulatory cytokine of the immune and nervous systems that acts on several processes, including mood regulation. This systematic review analyzed the IL1B (C-511T) (rs16944) variant’s CC and CT genotype frequencies and their associations with MDD in different populations while also verifying the TT genotype’s influence on response to antidepressant therapy. This review involved searching five databases, and articles were selected according to the PECOS inclusion criteria, resulting in eight articles. The findings highlight distinct clinical outcomes: the CC genotype was more frequently associated with greater MDD symptom severity, whereas the TT genotype was predominantly associated with antidepressant treatment response; thus, these associations should not be considered equivalent in terms of susceptibility to disease onset. However, despite these findings, other studies have found no significant association between this genetic variant and MDD. Therefore, further studies across different populations are needed to better understand the role of this polymorphism in the etiology of this disorder. Full article

Acne vulgaris is a common chronic inflammatory disorder of the pilosebaceous unit that is increasingly recognized as a condition linked to systemic metabolic disturbances. Growing evidence suggests that alterations in lipid metabolism, both in sebum composition and circulating lipid profiles, may play a key role in acne pathogenesis. This narrative review aims to summarize current knowledge on the relationships between lipid metabolism, body composition, diet, and acne. Acne vulgaris should be considered not only a dermatological condition but also a disorder with metabolic components. A deeper understanding of lipid-related mechanisms may support the development of more personalized and metabolically targeted therapeutic strategies. Full article

Background: As a crucial transitional period from campus to society, providing comprehensive undergraduate health psychological care is essential for addressing Social Anxiety Disorder (SAD). Current global healthcare research is actively exploring innovative digital interventions, with a specific focus on leveraging Augmented Reality (AR) as a transformative auxiliary tool in clinical settings. Methods: This study investigates the factors influencing the acceptance of AR-assisted Cognitive Behavioral Therapy (CBT) within student healthcare frameworks by developing a research model based on the Technology Acceptance Model (TAM). The framework incorporates key clinical and behavioral constructs: self-efficacy (SE), facilitating conditions (FC), and social influence (SI). Results: SE, FC, and SI significantly and positively impact the willingness to adopt AR technology for mental health purposes. Based on these findings, practical recommendations are provided for healthcare technology developers, therapists, and university psychological care providers to enhance the integration of AR-assisted CBT. Conclusions: Strengthening these digital pathways is vital for improving healthcare outcomes and enabling students to navigate future social and professional environments effectively. Because the sample consisted solely of Chinese undergraduate students, the findings should be interpreted within this specific cultural and educational context and require further validation in cross-cultural and multi-regional samples.

Background: Epilepsy is a complex neurological disorder in which growing evidence supports a significant role for the microbiota–gut–brain axis (MGBA) in modulating neuroinflammation, neuronal excitability, and treatment responsiveness. Beyond their traditional role in inducing ketosis, dietary therapies may influence epilepsy by modulating gut microbial ecology, intestinal barrier integrity, immune signaling, and microbiota-derived metabolites. Methods: This narrative review critically examines current clinical and experimental evidence regarding the relationship between epilepsy, gut microbiota, and dietary interventions. Particular attention was given to ketogenic dietary therapies, the Modified Atkins Diet (MAD), low-glycemic-index treatment (LGIT), Mediterranean dietary patterns, restrictive diets, and microbiota-targeted supplementation, including probiotics, prebiotics, and postbiotics. Results: Available evidence suggests that patients with epilepsy exhibit alterations in gut microbial composition associated with impaired short-chain fatty acid production, intestinal inflammation, and altered neuroimmune regulation. Ketogenic and microbiota-supportive dietary approaches may modulate these pathways beyond ketosis alone, potentially contributing to seizure reduction through integrated metabolic, inflammatory, and microbial mechanisms. Emerging evidence also supports a role for probiotics, prebiotics, and postbiotics in modulating gut–brain communication and neuroinflammatory signaling, although current clinical data remain limited. Conclusions: Dietary therapies in epilepsy should no longer be viewed exclusively as metabolic interventions aimed at inducing ketosis, but rather as potential modulators of the microbiota–gut–brain axis and neuroimmune homeostasis. While further mechanistic and clinical studies are needed, microbiota-targeted nutritional approaches may represent valuable complementary strategies to be integrated alongside conventional antiseizure therapies within more personalized models of epilepsy management.

Transcranial magnetic stimulation-electroencephalography (TMS–EEG) biomarkers have recently become available as a means to obtain new understanding of the causal chains of neuronal signaling in the brain. This is a key piece in the puzzle of how the brain is organized and how it works. Using dMRI tractography, we can map the circuit beneath a chosen cortical target; TMS can then stimulate it, and EEG records responses that reflect—and may even be caused by—activity in that structural circuit. The chain of events after stimulus delivery can be observed and quantified using current neuroimaging and TMS–EEG technology, a matter of tremendous relevance on how to approach novel therapeutic approaches in clinical conditions. Herein, we elaborate upon a perspective of how groundbreaking multi-locus TMS (mTMS) technology associated with EEG and multimodal neuroimaging can be applied to modulate the flow dynamics of the glymphatic system (GS). The enhancement of the GS waste clearance functionality has been shown to improve significantly symptom severity in neurodegenerative disorders such as Alzheimer’s (AD) and Parkinson’s disease (PD) or long COVID. In this perspective paper, we consider that next-generation therapeutics using versatile technologies such as noninvasive neuromodulation and neuroimaging will provide important benefits in public health and in how society can address the management of these difficult-to-deal-with ailments more effectively.

Introduction: Eosinophilic esophagitis (EoE) is a chronic immune-mediated esophageal disease characterized by eosinophilic infiltration, epithelial barrier dysfunction, and progressive tissue remodeling. Increasing evidence identifies eosinophils as central drivers of inflammation and fibrosis, linking EoE to type 2 immune responses and allergic disorders. However, the molecular mechanisms underlying eosinophil-mediated esophageal damage and their interaction with gastroesophageal reflux disease (GERD) remain incompletely understood. Material and Methods: A comprehensive narrative review of the current literature was conducted, focusing on studies investigating eosinophil biology, inflammatory signaling pathways, epithelial remodeling, fibrosis, and therapeutic targets in EoE. Clinical, translational, and experimental studies evaluating the association between EoE, GERD, and allergic comorbidities were critically analyzed. Results: Available evidence demonstrates that eosinophils actively contribute to EoE pathogenesis through the release of cytotoxic granule proteins, cytokines, chemokines, and lipid mediators, leading to chronic inflammation and fibrostenotic remodeling. Dysregulation of type 2 cytokines, particularly IL-4, IL-5, and IL-13, plays a pivotal role in disease progression and immune cell recruitment. Significant overlap between EoE and GERD suggests shared inflammatory mechanisms and diagnostic challenges. Furthermore, EoE frequently coexists with systemic allergic diseases, supporting the concept of a broader atopic inflammatory phenotype. Emerging biologic therapies targeting eosinophilic and type 2 inflammatory pathways have shown promising efficacy in reducing symptoms and histologic activity. Conclusions: Eosinophils represent key regulators of EoE pathobiology and constitute promising biomarkers and therapeutic targets. A deeper understanding of eosinophil-driven inflammatory networks may improve diagnostic accuracy, patient stratification, and the development of personalized therapeutic strategies for EoE and related esophageal inflammatory disorders.

Variants in the glucocerebrosidase gene (GBA1) are the predominant genetic risk factor for Parkinson’s disease (PD), often accelerating disease progression. While biological sex modulates PD progression, the longitudinal association between rasagiline (a monoamine oxidase-B [MAO-B] inhibitor) and motor outcomes in GBA1-associated Parkinson’s disease (GBA1-PD) remains unclear. This retrospective cohort study (2019–2026) analyzed 259 patients with PD (106 females, 153 males) with a median follow-up of 1.56 years to evaluate the association between rasagiline use and motor decline, emphasizing sex-stratified outcomes. Motor progression was evaluated using the Movement Disorder Society—Unified Parkinson’s Disease Rating Scale part III (MDS-UPDRS-III). Rates of change were calculated using sex-stratified Generalized Estimating Equations models, with adjustment for age at diagnosis to evaluate treatment effects and sex-specific associations. Among 259 patients, rasagiline use was associated with a significantly slower annual rate of motor decline (Slope Difference: −0.95; p = 0.03). In the GBA1-PD subgroup, females using rasagiline exhibited a clinically relevant slower rate of progression (approximately 1 point/year on the MDS-UPDRS-III) compared with non-users, although not statistically significant (p = 0.08); no association was observed in males. These findings suggest a potential sex-specific association of rasagiline with motor progression in GBA1-PD. Results highlight the importance of sex-stratified analyses to support personalized therapeutic approaches for PD genetic variants. Full article

Background/Objectives: Borderline personality disorder (BPD) is a severe mental disorder characterised by emotion dysregulation, impulsivity and interpersonal hypersensitivity. Its prevalence ranges from 0.5% to 6.4%. Eye tracking and pupillometry provide objective indices of social attention and inhibitory control, but the BPD literature using these techniques has not been systematically reviewed. The aim of this work was to synthesise the empirical evidence on visuo-attentional and pupillary alterations in BPD. Methods: Following the PRISMA 2020 statement, Web of Science, Scopus and PubMed were searched up to 13 March 2026, with no date or language restrictions. Search terms combined borderline personality disorder and eye-tracking constructs. Two reviewers independently screened records with complete inter-rater agreement at the title-and-abstract stage (Cohen’s κ = 1.00); two generative artificial-intelligence assistants (ChatGPT, NotebookLM) were additionally consulted as a non-systematic plausibility check and returned no eligible studies beyond the database search. Risk of bias was appraised with the framework appropriate to each study design (RoB 2 for randomised trials and Newcastle–Ottawa Scale logic for observational studies, with ROBINS-I held in reserve for non-randomised intervention designs). Results: Seventeen studies met the inclusion criteria, with sample sizes ranging from 19 to 164 participants and predominantly adult female samples. Designs included antisaccade and oculomotor tasks, free-viewing, dot-probe, affective priming and pharmacological challenge. Four findings recurred across studies. First, patients with BPD showed an early reflexive vigilance to the eye region of emotional and neutral faces, followed by reduced time on positive stimuli during longer presentations. Second, self-reported impulsivity was elevated, but laboratory inhibition was largely preserved; the deficits that did emerge were limited to preparatory control and were greater in patients with comorbid ADHD or under induced negative affect. Third, autonomic dysregulation was indexed by lower heart-rate variability and a larger baseline pupil size; in a single longitudinal study, pupillary reactivity was prospectively associated with subsequent symptom change. Finally, intranasal oxytocin reduced amygdala-driven vigilance. Conclusions: Eye-tracking and pupillometric measures appear to capture meaningful aspects of the BPD clinical picture. The two-stage profile of early vigilance followed by reduced sustained engagement is most parsimoniously described as a vigilance–avoidance pattern, which is compatible with, but not uniquely explained by, the hypersensitivity hypothesis of emotion dysregulation. Because thirteen of the seventeen studies recruited women only, these conclusions apply primarily to adult women with BPD. Methodological heterogeneity, the predominance of female samples and the scarcity of longitudinal data justify the need for standardised protocols, transdiagnostic comparisons and the inclusion of male and gender-diverse populations in future research.

Background: Arabic-speaking populations lack a brief, psychometrically evaluated instrument for assessing maladaptive personality traits within the DSM-5 Alternative Model for Personality Disorders (AMPD). Objective: To translate the Personality Inventory for DSM-5—Brief Form (PID-5-BF) into Standard Arabic and evaluate its content validity, reliability, and factor structure in a Saudi community sample. Methods: The PID-5-BF was translated through a multistep forward–backward procedure with expert panel review. Twenty-five pilot participants rated item clarity and simplicity. The final Arabic version was administered to 328 Saudi adults, and 52 verified pairs completed it twice over a mean interval of 16.1 days. Confirmatory factor analysis (CFA) tested the a priori five-factor model. Principal axis factoring with Promax rotation and Horn’s parallel analysis were used to examine factor retention. Reliability indices included Cronbach’s alpha and intraclass correlation coefficients [ICC(2,1), absolute agreement]. Results: Content validity was excellent (S-CVI/Ave = 0.93 for clarity; 0.94 for simplicity). CFA showed an acceptable RMSEA (0.068, 90% CI 0.062–0.075) but incremental fit below thresholds (CFI = 0.84; TLI = 0.82; SRMR = 0.12). Parallel analysis retained four factors. Domain alphas ranged from 0.70 to 0.78 (total = 0.89), and domain ICCs were 0.74 to 0.85 (total = 0.88). Antagonism items showed 50–58% floor effects. Conclusions: The standard-Arabic PID-5-BF shows acceptable content validity, internal consistency, and temporal stability, with partial structural support. Further work using ordinal estimation, measurement invariance testing, and external validity assessment is needed before routine clinical adoption. Full article

Background/Objectives: Diabetes mellitus (DM) is a group of chronic metabolic disorders characterised by persistent hyperglycaemia and an increasing global prevalence, imposing a significant socioeconomic and healthcare burden. Among its associated complications, the diabetic foot is a critical condition that doubles the risk of mortality. Although therapeutic footwear is an essential preventive strategy, research on treatment adherence has predominantly focused on quantitative parameters. This protocol aims to explore the experiences, needs, and perceived barriers of people with DM regarding therapeutic footwear use from a qualitative perspective. Methods: A qualitative focus group study will be conducted in the province of Alicante, Spain. Participants will be adults with a confirmed diagnosis of DM recruited across IWGDF foot risk categories 1–3 through purposive sampling. A total of 8–10 focus groups of 10–12 participants will be conducted in separate in-person and online modalities. Data will be analysed using reflexive thematic analysis within a constructivist epistemological framework, following the six-phase approach proposed by Braun and Clarke. The study adheres to the Consolidated Criteria for Reporting Qualitative Research (COREQ). Ethical approval will be obtained from the relevant Ethics Committee prior to data collection. Results/Expected Outcomes: The findings are anticipated to generate patient-centred, evidence-based insights into the psychosocial and experiential dimensions of therapeutic footwear adherence, informing the development of novel educational strategies and improvements in footwear design to optimise treatment adherence and clinical outcomes. Conclusions: This protocol provides a rigorous and transparent methodological framework for qualitative investigation of therapeutic footwear adherence in people with DM, contributing to a more comprehensive and person-centred approach to diabetic foot prevention.
