Accurate sex identification in reptiles with genotypic sex determination is essential for breeding management, veterinary care and evolutionary research, yet commonly used methods are often invasive, stressful or unreliable. This study aimed to evaluate a dosage-based quantitative PCR approach for molecular sex determination in caenophidian snakes, using naturally shed epidermal skin as a non-invasive DNA source. Genomic DNA extracted from shed skin was analysed by qPCR targeting conserved Z-linked genes (ADARB2, ARMC4 and TANC2), together with autosomal and reference genes, to assess sex-specific differences in gene copy number. Sixteen caenophidian snake species were examined, including taxa for which molecular sexing data are currently scarce or unavailable. The autosomal control gene showed dosage ratios close to parity between sexes, supporting DNA quality and reference gene reliability; meanwhile, Z-linked markers generally exhibited reduced dosage in females relative to males, consistent with a ZZ/ZW sex determination system. These results demonstrate that dosage-based qPCR applied to shed epidermal skin provides a promising and non-invasive framework for molecular sex determination in caenophidian snakes, without compromising animal welfare.

Advances in pediatric oncology have markedly improved survival, shifting attention toward long-term treatment-related morbidity. Targeted agents and immune-based therapies are now widely used across pediatric malignancies and selected non-malignant conditions, often for prolonged periods and during critical windows of growth and development. Because many therapeutic targets regulate physiological pathways involved in growth, pubertal maturation, gonadal function, bone metabolism, and energy homeostasis, clinically relevant endocrine toxicity may emerge during treatment or become apparent only with extended follow-up. This narrative review summarizes pediatric evidence on endocrine and metabolic effects associated with major classes of targeted and immune-based therapies, including tyrosine kinase inhibitors, mTOR inhibitors, MAPK-pathway inhibitors (BRAF/MEK), TRK inhibitors, ALK inhibitors, immune checkpoint inhibitors, and immune effector therapies. Distinct patterns of endocrine vulnerability emerge across drug classes: growth impairment and bone–mineral alterations are most consistently reported with tyrosine kinase inhibitors; weight gain and metabolic changes predominate with MAPK-, TRK-, and ALK-targeted agents; immune checkpoint inhibitors are characterized by early, multi-axis immune-related endocrinopathies with a high likelihood of permanent hormone deficiency once established. In contrast, endocrine abnormalities observed after immune effector therapies largely reflect indirect effects of systemic inflammation, corticosteroid exposure, and prior hematopoietic stem cell transplantation rather than direct endocrine toxicity. Given the limited pediatric-specific data, frequent confounding by multimodal therapy, and the potential for delayed or irreversible endocrine sequelae, structured endocrine monitoring and long-term survivorship care are essential for children exposed to modern anticancer therapies.

Health crises hinder the provision of intensive care for critical obstetric conditions such as preeclampsia and eclampsia, where timely decision making and system capacity directly impact maternal and fetal outcomes. This study compared the clinical and epidemiological profile and care processes in the ICU for cases of preeclampsia and eclampsia before and during the COVID-19 health crisis in Alto Amazonas, Loreto (Peru), using a comparative mixed-method approach. Quantitative data were obtained from ICU medical records for two periods (2015–2019 and 2020–2022). Categorical variables were compared using exact methods (Fisher’s exact test for 2 × 2 tables and exact procedures for scatter tables with multiple categories), and continuous variables were compared using nonparametric tests where appropriate. The most notable change was an increase in the frequency of cesarean sections during the health crisis, which should be interpreted with caution given the small sample size and potential changes in admission criteria and system limitations. Other clinical indicators and discharge status showed no clear evidence of substantial differences between the periods. Qualitative findings highlighted systemic limitations affecting continuity of care, particularly those related to timely access to safe blood products and referral pathways. These results align with SDG 3 (Good Health and Well-being) and support strengthening preparedness, referral coordination, and the availability of essential resources to protect maternal health during large-scale emergencies.

Creutzfeldt–Jakob disease (CJD) is a rare and still fatal neurodegenerative disorder caused by prion protein misfolding in the central nervous system. Accumulation of the pathogenic isoform leads to neuronal damage, spongiform degeneration, and rapidly progressive dementia. The disease is divided into sporadic, familial, iatrogenic, and variant forms, with sporadic cases accounting for the majority of cases. Diagnosis remains challenging and relies on a combination of clinical assessment, neuroimaging, and laboratory biomarkers. Key diagnostic methods include electroencephalography, Magnetic Resonance Imaging, and cerebrospinal fluid analysis for proteins as well as advanced amplification tests that improve diagnostic accuracy. Despite these advances, early detection remains challenging and misdiagnosis can occur. Currently, there is no effective disease-modifying therapy, and treatment is primarily supportive, focusing on symptom control and palliative care. Ongoing research aims to better understand the molecular mechanisms underlying prion propagation and develop targeted therapeutic strategies. This review summarizes current diagnostic methods and therapeutic approaches, focusing on molecular applications and their potential clinical implications. Full article

Background/Objectives: Japan’s mental healthcare system is characterized by the world’s highest number of psychiatric beds, widespread “social hospitalization,” and a structurally entrenched managerial support model that frequently undermines patient autonomy. Joint Crisis Plans (JCPs)—collaboratively developed crisis management documents—have been increasingly adopted as a care coordination tool; however, their role in transforming professional practice towards recovery-oriented support remains underexplored. This study aimed to elucidate the experiences of professionals utilizing JCPs across diverse facility types and to develop a theoretical understanding of the process by which they redefine their role from ‘manager’ to ‘recovery companion’. Methods: A qualitative design using the Modified Grounded Theory Approach (M-GTA), grounded in symbolic interactionism, was employed. Semi-structured interviews were conducted with 13 professionals (7 nurses, 6 mental health and welfare workers) across nine facilities (psychiatric hospitals, 24-h residential facilities, outpatient facilities) in the Kanto region of Japan. Theoretical sampling continued until saturation. Data were analyzed using the constant comparative method, with validity ensured through team checking. Results: Nine categories and 23 subcategories were extracted. A three-stage support transformation process emerged: (1) Stage of Motivation and Initial Support, in which professionals confronted the limitations of managerial practice; (2) Stage of Collaborative Role Redefinition and Practice, involving joint crisis management, strength-based support, and network building; and (3) Stage of Integration of Support Perspectives and Recovery-Oriented Practice, in which professionals witnessed individual recovery and integrated new support values into their practice. Negative cases revealed that JCP effectiveness is contingent on the co-construction of shared meaning rather than procedural compliance. Conclusions: JCP was suggested to function as a potential tool to facilitate navigating and reframing structural managerial barriers in Japanese mental healthcare. The creation of a shared language through JCP was associated with supporting conditions for individual self-determination, alleviating professional conflicts, and contributing to shifts in organizational culture.

Social determinants of health (SDoH) are non-medical factors shaped by the socioeconomic status of individuals or communities that influence the onset and progression of diseases and affect their outcomes. We have narratively analyzed the most important findings relating chronic kidney disease (CKD) and SDoH, evaluating the following items: (i) medical care and social determinants of health, (ii) socioeconomic risk for kidney disease at the individual level and (iii) socioeconomic risk for kidney disease at the population level. SDoH can be categorized by how they influence a person’s daily life. Individual factors include personal lifestyle choices such as smoking habits, alcohol consumption, and how a patient spends their non-working time. Community factors include structural elements such as average household income, educational attainment, employment rates, and the quality of the surrounding physical environment. Research consistently shows that a low socioeconomic status is a primary driver of poor clinical outcomes. While healthcare systems vary globally, the negative impact of socioeconomic deprivation on CKD patients remains a constant. Disadvantaged patients experience a faster loss of renal function, and there is a significantly higher incidence of cardiovascular events and mortality compared to those with financial stability. Financial hardship often leads to a “double burden,” where the struggle to afford care triggers a decline in both physical health and mental well-being. To improve patient care, it is essential to raise awareness among healthcare providers regarding the profound impact of these social factors. More precise data and thorough research are needed to fully understand these associations and develop targeted interventions. Full article

Background/Objectives: Antimicrobial resistance (AMR) is a critical global public health challenge driven by inappropriate and excessive antimicrobial use (AMU) across human, animal, and environmental sectors. Method: This narrative review synthesizes recent evidence on antimicrobial utilization and resistance patterns. A structured search of PubMed, Scopus, and Web of Science was conducted for studies published between 2015 and 2025. Eligible sources included surveillance reports, registry-based analyses, and clinical studies. Data were qualitatively analyzed to identify key trends and regional variations. Result: Marked geographical variation in AMR was observed. Carbapenem resistance in Escherichia coli remains low globally (2–3%) but is higher in Southeast Asia (17–18%) and India (~40%). Klebsiella pneumoniae shows consistently high resistance (>40% globally; ~54% in India), while Pseudomonas aeruginosa exhibits stable resistance levels (35–45%). Resistance prevalence increases from primary to tertiary care settings, reflecting greater antimicrobial exposure. Vulnerable populations—including pediatric, elderly, pregnant, and immunocompromised patients—face higher risks of antimicrobial exposure and adverse outcomes, including nephrotoxicity, hepatotoxicity, and microbiome disruption. WHO AWaRe data indicate a global shift toward increased use of Watch-category antibiotics. Stewardship interventions, such as audit and feedback, prescribing restrictions, rapid diagnostics, and decision support systems, effectively reduce inappropriate AMU. Conclusions: Integrated, data-driven antimicrobial stewardship and robust surveillance systems are essential to mitigate the global burden of AMR. Full article

Background and Objectives: Acute exacerbation of COPD (AECOPD) poses a major burden on healthcare systems, with critically ill AECOPD patients having increased morbidity and mortality. Since adverse outcomes are due both to respiratory failure and the systemic inflammatory response, prognostic markers accounting for these patterns are needed. Our aim was to investigate the predictive power of derived hematological indices for intensive care unit (ICU) mortality in patients with non-infectious versus infectious AECOPD. Materials and Methods: This is a retrospective, observational, monocentric cohort study on 88 AECOPD patients admitted to the ICU between 2018 and 2023. Descriptive statistics were performed for the entire cohort, and for predefined subgroups (non-infectious, infectious and bacterial AECOPD). Receiver Operating Characteristics (ROC) analysis was performed to test the predictive power of the studied indices. Cut-off values were identified using the Youden index. Kaplan–Meier analysis was conducted to test the association with ICU mortality. Results: Overall ICU mortality was 44%. For the whole cohort, neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-platelets ratio (NPR) and systemic inflammation response index (SIRI) showed moderate predictive power for ICU mortality (areas under the curve (AUCs) of 0.71–0.73). Non-infectious and infectious subgroups were comparable in terms of size, demographics, comorbidities and baseline COPD characteristics (p > 0.05). Mortality was significantly higher in infectious AECOPD (64.6% versus 20%, p < 0.001). For non-infectious AECOPD, monocyte-to-lymphocyte ratio (MLR) and SIRI had very good predictive power (AUCs between 0.82 and 0.855), while NPR and systemic inflammation index (SII) showed moderate AUC values (between 0.7 and 0.79). In infectious AECOPD, only NPR retained fair predictive power (AUC 0.691), which improved in bacterial AECOPD (AUC 0.781). Conclusions: Derived hematological indices have different predictive values for ICU mortality. MLR and SIRI exhibited very good predictive power in non-infectious AECOPD, while NPR was the best discriminator in bacterial AECOPD. These stress the importance of individualized prognostication in AECOPD. Full article

Background/Objectives: Chronic diseases pose a major challenge for healthcare systems, requiring integrated, patient-centered approaches that combine clinical management, prevention, and self-care. Lifestyle Medicine (LM) and lifestyle in general offers complementary frameworks to address these needs. However, the potential integration of LM within community nursing—particularly through the role of Family and Community Nurse (FCN)—has not been comprehensively synthesized. This narrative review aimed to synthesize international evidence on the role of community nursing—particularly FCN—in integrating chronic care management and LM view. Methods: For quality assessment, a narrative review was conducted in accordance with the SANRA criteria to enable the integration of heterogeneous evidence and a comprehensive synthesis of this complex topic. Literature searches were performed in the PubMed–Medline database, and the final screening of references from included studies was used to identify relevant manuscripts. Primary studies published in English over the past ten years were screened and analyzed using the PICOS framework. Sixteen eligible studies were included in the final synthesis. Results: The included studies indicated that nurse-led community interventions in LM view were associated with improvements in self-management, treatment adherence, and selected clinical outcomes, such as blood pressure, glycated hemoglobin, and physical activity levels. Empowerment-based approaches and the use of digital or telehealth tools supported patient engagement and health literacy. At the organizational level, multidisciplinary collaboration, shared protocols, and professional leadership emerged as key factors in sustaining continuity and quality of care, while organizational fragmentation and limited training in behavioral counseling were commonly reported barriers. Conclusions: Community nursing, particularly through FCNs, plays a relevant role in integrating chronic care management and LM approaches, contributing to improved self-management, treatment adherence, and selected clinical outcomes. The evidence highlights the importance of empowerment-based interventions, digital support tools, and multidisciplinary collaboration in enhancing care continuity and patient engagement. Addressing organizational barriers and strengthening behavioral counseling training remain essential to support effective implementation in community settings. Full article

Background: Pleuroparenchymal fibroelastosis (PPFE) is a rare fibroelastotic lung disease characterized histologically by dense pleural and subpleural fibrosis with upper-lobe predominance. In clinical practice, diagnosis often relies on characteristic radiologic findings, as surgical lung biopsy is rarely feasible. Unlike idiopathic pulmonary fibrosis, robust radiologic criteria validated against biopsy-proven cohorts remain limited, and the diagnostic performance of imaging alone is incompletely defined. Although initially described as idiopathic, PPFE is increasingly recognized in secondary settings, including connective tissue disease-associated interstitial lung disease (CTD-ILD), where it frequently overlaps with more common fibrotic patterns. Methods: We conducted a focused narrative review of the literature on PPFE in CTD-ILD, synthesizing evidence on morphology, epidemiology, clinical course, prognostic implications, and proposed pathobiological mechanisms, with emphasis on distinguishing true PPFE from PPFE-like lesions. Results: CTD-associated PPFE is associated with accelerated lung function decline, increased risk of pneumothorax, and poorer outcomes, particularly in systemic sclerosis and rheumatoid arthritis. However, distinguishing true PPFE from radiologic mimics remains challenging, and diagnostic approaches rely heavily on imaging without robust histopathologic validation. Proposed mechanisms include epithelial injury, immune dysregulation, and vascular or lymphatic abnormalities, although causal links remain unproven. Significant gaps persist regarding natural history and therapeutic responsiveness. Conclusions: Earlier identification of PPFE in CTD-ILD is important, as misclassification may delay risk stratification and management. Longitudinal imaging, multidisciplinary evaluation, and standardized diagnostic criteria are needed to improve clinical care and guide future research. Full article

Background: Subacute sclerosing panencephalitis (SSPE) is a chronic, progressive disease of the central nervous system (CNS) caused by persistent infection at this level with the wild measles virus. Its incidence is negatively correlated with measles vaccination coverage. The pathogenesis isn’t fully understood, but infection before the age of 2 is an important risk factor. Methods: This is a retrospective observational study conducted at the Louis Turcanu Emergency Children’s Hospital in Timisoara, Romania, based on the analysis of the medical records of patients diagnosed with SSPE between January 2021 and December 2025. We analyzed demographic and epidemiological factors, clinical and paraclinical findings, management, and outcomes. Results: Seven children were diagnosed during the study period, with a mean age of 8.4 years (range 7–11 years). Six of them had contracted measles during their first year of life, and one at the age of four. The mean latency period was 7.1 years (range 4–9 years). On admission, all patients presented symptoms consistent with clinical stage II, with periodic slow wave discharges on electroencephalogram (EEG). The initial brain Magnetic Resonance Imaging (MRI) was normal in two cases, while revealing varied abnormalities in all others. Despite complex treatment with isoprinosine and anticonvulsants, progressive cognitive and neurological deterioration continued in all patients. Conclusions: SSPE is a rare but serious, debilitating disease despite its complex, multidisciplinary care. Following a 10-year SSPE-free period, the reappearance of these pediatric cases constitutes a public health alert, unequivocally demonstrating the importance of measles vaccination. Full article

Increasing water demand and the rising complexity of wastewater matrices, driven by pharmaceuticals, personal care products, and recalcitrant industrial contaminants, require advanced catalytic solutions capable of efficient mineralization under sustainable conditions. Solar-driven processes have attracted growing attention; however, ultraviolet disinfection, heterogeneous photocatalysis, and photo-Fenton systems are commonly treated as independent approaches without mechanistic integration. This review presents a unified photonic–thermal catalytic framework for solar-driven wastewater treatment, emphasizing the interplay between photon absorption, charge-carrier separation, reactive oxygen species generation, and radical-mediated oxidation pathways. The contributions of ultraviolet, visible, and infrared radiation are analyzed in terms of catalyst activation, persulfate and ozone activation mechanisms, and temperature-enhanced reaction kinetics governed by Arrhenius behavior. Particular attention is given to photothermal effects that modulate surface reaction rates, mass transfer, and catalyst stability. By integrating mechanistic insights with reactor-level considerations, this work provides a rational basis for the design of robust solar catalytic systems with enhanced activity, selectivity, and scalability for real wastewater applications.

Large-scale surface subsidence induced by extra-thick seam longwall top-coal caving (LTCC) is strongly amplified by thick unconsolidated overburden, posing serious serviceability risks to overlying linear infrastructure. Taking the S103 Provincial Highway above Panel 6118 in Inner Mongolia, China, as the engineering background, this study integrates theoretical analysis, numerical simulation, and in situ monitoring to investigate the subsidence-control mechanism of directional presplitting roof cutting. The results show that roof cutting mitigates surface subsidence by reconstructing the overburden structural system and weakening the stress-transfer chain, thereby transforming key-stratum deformation from integral bending to segmented block movement and narrowing the subsidence-affected zone. An equivalent mining-depth model for subsidence-boundary convergence is proposed to characterize the inward migration of the subsidence-basin boundary under thick unconsolidated cover, and a segmented probability-integral model is developed to explain the kink-like high-gradient feature in the post-cut subsidence profile. Parametric simulations of roof-cutting positions (p = 0, 2, 4, …, 32 m) show that the most effective mitigation occurs in the range p = 4–12 m; using minimum–maximum highway subsidence together with profile flattening as the optimization criteria, the representative optimum is identified at p ≈ 10 m, for which the maximum highway subsidence is approximately 57 mm, about 76% lower than that in the non-cutting case. The results further indicate that, although roof cutting significantly reduces subsidence and deformation gradients, fissure localization and possible discontinuous deformation near the pre-split weak plane still require careful field monitoring.

Background/Objectives: Spinal cord injury (SCI) leads to long-term changes in mobility, bodily function, and everyday participation, extending beyond physical impairment to affect autonomy, identity, and social inclusion. In Greece, limited community-based rehabilitation services, environmental inaccessibility, and fragmented follow-up care further shape the lived experience of individuals with SCI. This study aimed to explore the lived experiences and perceived rehabilitation needs of people with paraplegia living in the community, adopting a phenomenological approach to understand rehabilitation as an ongoing process of reclaiming autonomy, dignity, and participation. Methods: A qualitative phenomenological design was employed. In-depth semi-structured interviews were conducted with fourteen individuals with paraplegia following SCI. Data were analyzed using Braun and Clarke’s reflexive thematic analysis, supported by ATLAS.ti software. Results: Participants described living with SCI as a ‘Socially lived disability: a daily confrontation with an inadequate system and the ongoing struggle for accessibility, autonomy, and dignity’ (Overarching Theme). Participants’ experiences were organized into six themes: (A) facing the new reality, (B) barriers and facilitators of independent living, (C) role and importance of rehabilitation, (D) me and others around me, my difference, (E) the need for adequately trained and informed health professionals and caregivers, (F) ageing as an additional challenge. Conclusions: Living with SCI is experienced as an ongoing process of embodied and social reorientation, in which autonomy, participation, and dignity are continuously negotiated rather than restored once and for all. Rehabilitation emerges as a lifelong, person-centered process that extends beyond functional recovery to support bodily confidence, accessibility, social inclusion, and quality of life across the life course. These findings highlight the need for coordinated, community-based rehabilitation systems, accessible environments, and adequately trained health professionals capable of addressing the evolving functional, social, and existential realities of individuals living with SCI.

Background/Objectives: NF2-related schwannomatosis (NF2-SWN) is a genetic tumor predisposition syndrome of the nervous system caused by pathogenic variants in NF2 encoding the merlin tumor suppressor. Truncating variants in NF2 cause severe phenotypes with higher tumor burden, early mortality, and a lifetime need for multiple surgeries due to lack of medications that control schwannoma growth. Methods: We developed a functional precision medicine (FPM)-inspired workflow to identify drug sensitivities in cells isolated from a pediatric severe NF2-SWN patient’s spinal and peripheral schwannomas. Transcriptomic profiling, high-content drug sensitivity assays, tissue and isolated cell immunostaining, flow cytometry, and capillary-based immunoblotting were used to study the available tissues. Results: Aberrant merlin-dependent pathway expression was conserved between the spinal schwannoma and its cultured primary cells. Drug sensitivity screens in 2- and 3-dimensional formats revealed cytotoxic effects of fimepinostat in primary cells; dasatinib with brigatinib was the most effective cytostatic combination. Ineffective therapies attempted in the patient were also ineffective ex vivo. Conclusions: These data support the idea of using the FPM workflow to improve and individualize the standard of care for severe NF2-SWN patients using surgical samples. Full article
