Background: Routine fundus photography is widely accessible; however, its utility in stratifying systemic vascular risk in asymptomatic, general populations remains understudied. We utilized a large-scale health screening cohort in South Korea to evaluate the clinical validity of the retinal arteriosclerosis index (RAI) in a generally healthy population. Methods: We conducted a cross-sectional study of 74,608 adults who underwent routine health screening (2003–2010) at a tertiary center. Retinal arteriosclerosis was graded (0–4) by masked readers with a modified Scheie classification; a higher eye grade was defined as a person-level grade. High-grade RAI was prespecified as ≥2. Associations with systemic conditions (hypertension, type 2 diabetes, hyperlipidemia, metabolic syndrome, cardiovascular disease, and stroke) were examined by using multivariable logistic regression adjusted for demographic, lifestyle, and laboratory covariates; moreover, analyses were stratified by age and sex. Results: High-grade RAI was present in 4.5% of the participants and increased with age. After adjustment, high-grade RAI was associated with hypertension (OR, 2.97; 95% CI, 2.73–3.23), diabetes mellitus (OR, 1.35; 95% CI, 1.22–1.50), cardiovascular disease (OR, 1.46; 95% CI, 1.25–1.71), metabolic syndrome (OR, 1.63; 95% CI, 1.49–1.78), and stroke (OR, 1.98; 95% CI, 1.41–2.79) but not with hyperlipidemia. Sex-stratified analyses revealed broadly similar patterns, although high-grade RAI was associated with stroke in women and cardiovascular disease in men. Age-stratified analyses demonstrated consistent associations with hypertension, metabolic syndrome, and stroke across all age groups, with stronger effect sizes being observed in younger individuals. With respect to lifestyle factors, frequent alcohol consumption was associated with higher odds of high-grade RAI. Laboratory correlates included higher uric acid levels and lower red blood cell, albumin, and bilirubin levels (all p < 0.001). Conclusions: Fundus-defined arteriosclerotic changes were independently associated with multiple systemic vascular and metabolic conditions. An association with stroke in adults younger than 40 years of age was also observed, although this finding should be interpreted with caution given the cross-sectional design and limited number of events. These findings support the potential role of retinal vascular changes as cross-sectional correlates of systemic vascular health. Longitudinal studies are needed to clarify temporal relationships and causality. Full article

Sepsis remains a leading cause of preventable morbidity and mortality worldwide, and adherence to the Centers for Medicare & Medicaid Services Severe Sepsis and Septic Shock Early Management Bundle (SEP-1) remains modest and variable across institutions. Simultaneously, controversy persists regarding fixed-volume fluid resuscitation mandates, particularly given the increasing emphasis on individualized, physiology-guided management. Artificial intelligence (AI) has emerged as a potential strategy to address both operational and clinical gaps in sepsis care. This review examines the current state of SEP-1 implementation, key barriers to compliance, and ongoing debates surrounding early fluid administration. We then discuss contemporary evidence on AI-enabled tools designed to accelerate bundle processes and support personalized fluid management. Early warning systems, natural language processing-augmented models, and telemedicine-integrated platforms have demonstrated improvements in process measures such as time-to-antibiotics and bundle component completion when embedded within defined clinical workflows. Reinforcement learning, causal machine learning, and predictive models offer promise for individualized fluid strategies, although most data remain retrospective and hypothesis-generating. Successful integration will require prospective validation, clinician-in-the-loop oversight, governance frameworks, and continuous monitoring for safety, equity, and model drift. AI should augment—rather than replace—clinical judgment to improve reliability, timeliness, and personalization in sepsis management. Full article

This review explores the hypothesis that schizophrenic symptoms may be understood not as isolated deficits, but as interconnected manifestations of a structural reorganization of consciousness. The premises of this work are grounded in a comparative matrix that suggests an underlying “consanguinity” between the philosopher’s voluntary epoché—the suspension of the natural attitude performed to study the inner workings of consciousness—and the involuntary “unworlding” passively experienced in schizophrenia. By exploring this shared ontological ground, the text suggests how specific phenomenological shifts, such as the collapse of the “vital drive,” may manifest as clinical markers; this process may eventually lead to an involuntary “transcendental reduction” where the mind’s internal machinery becomes an object of forced awareness. Building on these premises, the review tentatively outlines several key achievements. It addresses the substrate-subjectivity gap by linking biological sensory-binding failures to the onset of involuntary hyper-reflexivity. Regarding structural loss and gain of function, it suggests that the psychotic transition involves a simultaneous erosion of common-sense coherence and an intensified receptivity to unfiltered perceptual fragments, which may trigger a search for metaphysical meanings. In terms of a therapeutic synthesis, it proposes exploring the conversion of “artless decentering” into a manageable, strategic distance through mindfulness and person-centered position-taking. Finally, it discusses a potential nosographic evolution, advocating for future diagnostic classifications that prioritize the experiencing self and qualitative insights to support a more translational and empathetic approach to psychiatry.

The long-term coexistence of human-driven vehicles (HVs) and autonomous vehicles (AVs) in mixed traffic presents significant challenges for lane-change interactions on freeways. To address this, we propose a closed-loop decision-making framework, centered on Social Value Orientation (SVO), that covers the entire process from recognition to fallback execution. First, we use maximum-entropy inverse reinforcement learning (MaxEnt-IRL) to infer driver SVO parameters (${\theta }_{SVO}$) from the NGSIM dataset, quantifying the trade-off between selfish and cooperative behaviors as learnable weights. These parameters are then incorporated into a Transformer-based predictor via conditional embeddings, enabling the model to generate personalized trajectories from identical historical data. Furthermore, within a receding-horizon, game-theoretic framework, we combine preference-weighted payoffs with this conditional predictor and introduce a dynamic lane-change abort mechanism. This mechanism triggers a fallback maneuver, generated by an APF + MPC controller, if the expected return of continuing the lane change drops below that of aborting. Simulations across 1000 adversarial scenarios show that our method markedly improves the lane-change success rate and cruising efficiency compared to the IDM + MOBIL baseline. It also significantly reduces forced merges and hazardous events when encountering aggressive or selfish blocking vehicles, demonstrating the safety and robustness benefits of our preference-aware model and abort mechanism.

Background: Osteopathy’s integration into contemporary healthcare requires clear articulation of its theoretical and practical foundations and active engagement in interprofessional practice. Despite growing institutional recognition, conceptual ambiguity remains regarding foundational principles and their operationalization. Osteopathy is broadly described as a person-centered, evidence-informed discipline promoting health through manual and educational strategies within systemic and biopsychosocial contexts. Objectives: This Perspective critically examines osteopathic principles, proposes a shared conceptual model for interdisciplinary care, and outlines a structured research agenda for empirical validation, aiming to enhance person-centered, preventive, and sustainable practice. Methods: A narrative review synthesized historical, theoretical, and contemporary evidence. Records were thematically analyzed through expert collaborative brainstorming to achieve consensus, ensuring both conceptual and empirical rigor. Results: Twenty-two studies were included, forming two thematic areas: (1) historical evolution of osteopathic principles, encompassing foundational definitions, early interpretive divergences, codifications, and adaptations; and (2) contemporary reconceptualization for interdisciplinary care, integrating systems-oriented and biopsychosocial frameworks. Emphasis was placed on self-regulation, structure–function relationships, and holistic care. This synthesis bridges historical and modern insights, highlighting osteopathy’s relevance in integrative, pediatric, and preventive healthcare. Conclusions: Reconceptualizing osteopathic principles strengthens professional identity and supports sustainable, evidence-informed, person-centered practice. The proposed framework informs interprofessional collaboration and guides a research roadmap to validate and integrate osteopathy globally within contemporary healthcare systems. Full article

Transgenerationality refers to the psychological and behavioral elements transmitted across generations. It is intrinsically linked to unelaborated content—such as trauma, grief, secrets, conflicts, and shame—operating through implicit and partially unconscious pathways that manifest in individual behavior. In the context of nursing, transgenerationality explores how nursing care is influenced by these dynamics and how the concept can be utilized to achieve superior health-related outcomes, such as facilitating more effective healthcare transitions. Specifically, it examines how experiences, vulnerabilities, resilience factors, and health-related patterns transmitted across generations affect overall health. As a humanistic profession rooted in person-centered care, nursing must remain cognizant of the impact of this concept on healthcare. This is particularly relevant in clinical settings where nurses are pivotal practitioners, such as mental health, health literacy, chronic disease management, and healthcare transitions. Healthcare transitions represent critical periods in a person’s life, and nurses are present across all contexts to facilitate these shifts. A primary example is the transition from hospital to home, which illustrates the importance of understanding transgenerationality within the roles of both patients and caregivers. Understanding how this concept impacts healthcare allows for the perception of transition as a holistic process. Awareness of these transgenerational operations leads to more personalized care, fostering healthier and more seamless healthcare transitions. The general purpose of this paper is to define and operationalize the concept of transgenerationality within nursing care, emphasizing its critical role in achieving better health outcomes, particularly during hospital-to-home transitions.

Research self-efficacy (RSE) is significantly associated with research interest, scholarly productivity, and professional development. It is particularly critical in counselor education, a field centered on improving human well-being and advancing evidence-based practice. However, RSE is often conceptualized primarily as an intrapersonal construct, with its relational and contextual dimensions underexplored. In this study, we examined doctoral counseling students’ quantitative research self-efficacy (QRSE) within the context of a quantitative research course. We employed a convergent mixed-methods case study design to investigate QRSE development over one semester. Four qualitative themes emerged: (a) QRSE is associated with professional development level; (b) QRSE is domain- and topic-specific; (c) QRSE is shaped by curriculum design and instructor characteristics; and (d) QRSE is dynamic and evolving rather than static. Quantitative results demonstrated a fluctuating yet overall upward trend. The qualitative and quantitative findings largely converged, with qualitative data extending beyond the quantitative measures. We propose a preliminary conceptual cubic model representing four interconnected dimensions of QRSE: personal, contextual, relational, and temporal. This study offers an exploratory, multidimensional framework for understanding how these factors may jointly shape QRSE development and provides implications for research training in counselor education.

Purpose: The purpose of this study was to examine the effects of a medically centered, interdisciplinary treatment model on adaptive behavior in children with Autism Spectrum Disorder (ASD). The Cortica model involves a comprehensive program including behavioral and developmental therapies, overseen by a neurodevelopmental physician. Here, we investigated how adaptive behaviors change over time during care at Cortica. Methods: We analyzed changes in the Vineland Adaptive Behavior Scales over the course of Cortica care compared to a community sample comprising longitudinal data from the National Database for Autism Research (NDAR). Results: Using propensity score weights to match cohorts based on baseline functioning, multilevel growth curve models showed significant Cohort × Time interactions for the Adaptive Behavior Composite (ABC) score and all subscale scores, indicating increased growth in adaptive behavior skills for children in the Cortica cohort relative to NDAR. Conclusions: Results of this study highlight the importance of using adaptive behaviors as a primary outcome in clinical research studies and suggest that a personalized, multidisciplinary approach to intervention can result in improved adaptive behavior skills over time.

Adolescents and young people (AYP) experience a disproportionate burden of both mental health conditions and HIV, particularly in low- and middle-income countries (LMICs)-nations classified by the World Bank as having lower or middle economies. Mental health problems such as depression, anxiety, and substance use increase HIV (Human Immunodeficiency Virus that attacks the human immune system and leads to various illnesses when untreated) risk, and negatively affect treatment adherence and outcomes. However, mental health remains insufficiently integrated into HIV research and programming. Evidence on how mental health services are operationally integrated into HIV prevention and treatment for this population is limited and fragmented. This scoping review mapped existing evidence on the integration of mental health services into HIV treatment programs for AYP in LMICs, guided by PRISMA-ScR (a guideline used for reporting scoping reviews in research) and the Person–Concept–Context framework, a framework used to define specific research question in research. In this case, the population was adolescents and young people (10–24 years) receiving HIV prevention or treatment services, the concept referring to the integration of mental health interventions such as screening, assessment and counseling within HIV services, and the context focused on low- and middle-income countries (LMICs). PubMed, MEDLINE, Scopus and PsycINFO databases were searched for studies published between 2014 and 2024. Eligible studies reported mental health screening, assessment, treatment, or referral within HIV services for AYP in LMICs. Two reviewers independently screened studies, assessed full texts, and extracted data. Of 634 records identified, ten (10) studies met the inclusion criteria. All were conducted in Sub-Saharan Africa and primarily used qualitative or pilot designs. Four integration approaches were identified: routine mental health screening within HIV services, task-shifting to trained lay providers, peer-led and community-based psychosocial support, and culturally adapted, youth-centered psychological interventions. Common barriers included stigma, low mental health literacy, limited training and supervision, staffing constraints, and weak referral systems. Existing evidence is limited, remains exploratory, preliminary, and largely focused on feasibility and implementation experiences, suggesting that integrating mental health services within adolescent HIV care in LMICs may be feasible and acceptable when approaches are contextually adapted and participatory.

Background: Femoral pseudoaneurysms are clinically heterogeneous, with substantial variability in anatomical features and patient-related bleeding risk. Standard treatment algorithms may be inadequate, particularly in patients receiving anticoagulation or presenting with altered coagulation profiles. A personalized, risk-adapted interventional strategy may optimize outcomes while preserving procedural safety. This study compares ultrasound-guided compression with endovascular and percutaneous therapies and evaluates the safety of minimally invasive approaches across different risk profiles to support individualized management. Methods: This single-center retrospective cohort study included 65 consecutive patients treated for femoral pseudoaneurysms between January 2019 and May 2025. Treatment modalities comprised ultrasound-guided compression, endovascular embolization (coils, covered stents, NBCA–Lipiodol), percutaneous glue injection, and hybrid approaches. Primary endpoints were technical and clinical success. Safety was assessed using pre- and post-procedural INR, platelet count, and hemoglobin levels. High-risk status was defined as ongoing anticoagulation or antiplatelet therapy, INR > 1.5, or platelet count <50 × 10⁹/L. Results: Endovascular and percutaneous approaches achieved significantly higher technical (100% vs. 68.5%, p = 0.006) and clinical success rates (100% vs. 77.8%, p = 0.009) compared with ultrasound-guided compression. In minimally invasive cohorts, INR and platelet counts remained stable after treatment, while hemoglobin showed an expected post-procedural decrease (p < 0.001). High-risk patients demonstrated technical success rates comparable to standard-risk patients, with no significant differences in laboratory trends. Favorable outcomes were observed across different embolic materials. Conclusions: Endovascular and percutaneous therapies provide superior effectiveness compared with ultrasound-guided compression while maintaining a reassuring safety profile, even in patients at increased bleeding risk. These findings support a personalized, patient-tailored interventional approach based on individual anatomical and clinical characteristics. Full article

Erectile dysfunction (ED) is a common multifactorial condition with significant physical, psychological and relational consequences. While historically associated with aging, its rising prevalence among younger men underscores the need for updated diagnostic and therapeutic frameworks. This narrative review synthesizes contemporary evidence on the pathophysiology, diagnostic workup and management of ED, with emphasis on guideline-directed care and emerging treatment modalities. A comprehensive literature search was conducted, with evidence synthesized from key clinical guidelines, landmark trials and recent peer-reviewed studies. Lifestyle optimization remains the foundational step, followed by first-line pharmacotherapy with phosphodiesterase type 5 inhibitors (PDE5is), which demonstrate high efficacy and safety across diverse patient populations. For patients with inadequate PDE5is response, second-line options include alprostadil (intracavernosal, with approximately 70% success rates or intraurethral), vacuum erection devices and penile prosthesis surgery, with patient and partner satisfaction exceeding 95% for the latter when performed in experienced centers. Psychosexual therapy is an integral adjunct, particularly in psychogenic or mixed etiologies. Regenerative approaches such as low-intensity extracorporeal shockwave therapy (Li-SWT) and platelet-rich plasma (PRP) injections are under investigation; current evidence supports their use only in experimental settings due to limited long-term data. A multidisciplinary, individualized strategy—incorporating pharmacologic, surgical and psychosocial interventions—remains the cornerstone of modern ED management. This review critically distinguishes well-established evidence from ongoing clinical debates and translates findings into practical guidance for daily practice. Ongoing technological advances may further refine diagnostic accuracy and treatment personalization, but high-quality studies are needed to establish the role of regenerative and digital tools.

Tobacco use remains disproportionately high among adults living with mental illnesses (MIs), contributing to excess morbidity and mortality, particularly in high-burden states such as Kentucky. Behavioral healthcare providers are well-positioned to address this disparity but often lack formal training in evidence-based tobacco treatment. Tobacco Treatment Specialist (TTS) training provides healthcare providers with skills to deliver evidence-based tobacco treatment; however, traditional TTS training models often rely on synchronous, in-person or live virtual formats, which may limit accessibility for some healthcare workforces. Asynchronous, web-based delivery models may reduce these barriers. This study evaluates a targeted, asynchronous TTS training program designed for providers working in Community Mental Health Centers (CMHCs) across Kentucky between 2020 and 2024. Using a one-group post-test-only design to assess engagement and completion and a one-group pre-test–post-test design among completers, we examined program outcomes and changes in knowledge and attitudes. Eligible participants were nominated by the administrative team at each CMHC. Of 100 registered participants, 70.0% enrolled and 55.0% completed the program. Among completers (n = 55), knowledge scores increased significantly from pre- to post-test (t[51] = 7.6, p < 0.001). Participants also reported significant improvements in perceived skills (t[51] = 7.9, p < 0.001) and knowledge of resources to deliver tobacco treatment (t[51] = 7.8, p < 0.001), while perceived time to deliver services did not change significantly. These findings suggest that asynchronous TTS training is a feasible approach to improving tobacco treatment knowledge and confidence among behavioral health providers, though additional strategies may be needed to enhance completion and assess practice-level impact.

Introduction: Chronic subdural hematoma (CSDH) is a complex disease with an overall incidence of 1.7–20.6 per 100,000 persons per year and is more commonly encountered in the elderly population. It is projected to be one of the most common neurosurgical procedures. Postoperative delirium is a common complication associated with the elderly, causing increased morbidity and prolonged hospital stay. However, its risk factors in chronic subdural hematoma patients have not been well studied. Methods: A total of 202 consecutive patients with chronic subdural hematoma at different neurosurgical centers in Europe between January 2023 and June 2025 were enrolled. Various clinical indicators were analyzed to identify independent risk factors for postoperative delirium using univariate and multivariate regression analyses. Results: Out of the 202 patients (age, 71 (IQR, 18); female-to-male ratio, 1:2.7) studied, 63 (31.2%) experienced postoperative delirium. Univariate analysis identified age (p < 0.001), gender (p = 0.014), restraint belt use (p < 0.001), electrolyte imbalance (p < 0.001), visual analog scale (VAS) pain score (p < 0.001), hematoma thickness (p < 0.001), midline shift (p < 0.001), hematoma side (p = 0.013), hematoma location (p = 0.018), and urinal catheterization (p = 0.028) as significant factors. Multivariate regression analysis confirmed the significance of restraint belt use (B = 7.657, p < 0.001), electrolyte imbalance (B = −3.993, p = 0.001), VAS pain score (B = 2.331, p = 0.016), and midline shift (B = 0.335, p = 0.007). Hematoma thickness and age had no significant impact. Conclusions: Increased midline shift and VAS pain scores, alongside restraint belt use and electrolyte imbalance, elevate delirium risk in chronic subdural hematoma surgery. Our prediction models may offer a reference value in this context. Full article

Objectives: Small-cell lung cancer (SCLC) is an aggressive malignancy often diagnosed at the extensive stage (ES-SCLC). While chemoimmunotherapy (CIT) has emerged as a first-line option, SCLC’s “cold” immune profile limits broad efficacy. This study evaluates the real-world clinical efficacy of CIT versus chemotherapy (CT) alone and analyzes the association between gene mutation characteristics and clinical indicators. Methods: We retrospectively analyzed 170 patients with ES-SCLC treated at a single center between January 2020 and January 2024. Patients were categorized by first-line treatment (CIT vs. CT). Subgroup analyses were conducted to evaluate treatment response. Genomic profiling was integrated for a subset of patients to identify associations between mutation signatures and clinicopathological factors. Results: Of the 115 patients (67.6%) who received CIT and 55 (32.4%) who received CT, the CIT group achieved a significantly higher objective response rate (76.5% vs. 56.4%). Median progression-free survival was numerically but not significantly longer in the CIT group (6.0 vs. 5.8 months). Adrenal metastasis was identified as an independent adverse prognostic factor. Genomic analysis revealed site-specific correlations: MYC mutations with pleural metastasis, NTRK3 with brain metastasis, ALK with adrenal metastasis, and NTRK1 with intrapulmonary metastasis. Additionally, smokers showed higher mutation frequencies in SMAD4 and PIK3CA. Conclusions: CIT significantly improves initial response rates in ES-SCLC compared to CT alone. Baseline adrenal metastasis serves as a poor prognostic indicator. Distinct genomic mutation signatures are associated with clinical characteristics, suggesting potential pathways for personalized treatment strategies. Full article

The reorganization of academic work following the COVID-19 pandemic has intensified debate regarding the effects of work modality on faculty well-being, particularly in Latin American contexts characterized by structural inequalities and digital divides. This study examines the influence of work modality on the integrated well-being of university faculty in Peru. A quantitative, non-experimental explanatory design was employed with a sample of 448 faculty members from public and private universities. Occupational well-being and quality of life were assessed using validated instruments and subsequently integrated into a higher-order construct due to the absence of discriminant validity. Structural relationships were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with bootstrapping (5000 resamples). The results indicate that work modality significantly predicts integrated well-being (β = 0.823; p < 0.001), although the model explains a limited proportion of variance (R² = 0.168). Comparative analysis revealed that faculty in in-person modality report significantly higher levels of well-being and quality of life than those in virtual modality. These findings suggest that work modality operates as a structural condition shaping faculty well-being and highlight the need for institutional policies that promote balanced and human-centered work designs in higher education.
