Background and Objectives: Early assessment interventions are recommended for older adults with sarcopenia. Gait speed in older adults considerably decreases activities of daily living (ADL). However, the association between ADL and gait speed in older adults with sarcopenia has not yet been fully elucidated. This study aimed to clarify the association between walking speed and ADL in older adults with sarcopenia. Materials and Methods: A total of 72 older adults with sarcopenia who required support or care under Japan’s long-term care insurance system were included. Correlation and multivariate analyses were performed to examine the association between walking speed and ADL performance. A receiver operating characteristic analysis was used to evaluate the discrimination power of gait speed for ADL independence. Results: Gait speed was significantly and positively correlated with the Barthel Index scores for the men and women. ADL were independently and significantly associated with walking speed in the multivariate analysis. The threshold for gait speed that distinguished ADL independence in older adults with sarcopenia was 0.76 m/s (area under the curve = 0.75, sensitivity 72.7%, specificity 74.0%). Conclusions: Decreased gait speed in older adults with sarcopenia was associated with decreased ADL. Gait speed had high discriminatory power in identifying ADL independence. This indicates that an assessment intervention for gait speed in older adults with sarcopenia may have high clinical utility. Full article

Metformin is a promising small molecule for dentin regeneration, but an effective local delivery system for pulp applications has been underexplored. This study encapsulated metformin in poly(lactic-co-glycolic acid) (PLGA) microspheres and incorporated them into calcium phosphate–chitosan cement (CPCC) as a direct pulp-capping material (DPC). Metformin-PLGA microspheres were prepared by double emulsion and mixed with CPCC at a concentration of 0% to 20% by weight. Microsphere morphology, encapsulation efficiency, chemical composition, and physico-mechanical properties were characterized, and compatibility with human dental pulp stem cells (hDPSCs) was evaluated by live/dead assay and SEM. The microspheres were spherical (5.43 ± 0.17 µm) with (51 ± 3.69%) encapsulation efficiency, and FTIR confirmed metformin incorporation. The 15% Met-PLGA-CPCC group showed flexural strength (15.22 ± 1.98 MPa), elastic modulus (4.60 ± 0.73 GPa), and work of fracture (104.96 ± 12.48 J/m²) comparable to or higher than CPCC and MTA, while all Met-PLGA-CPCC groups had shorter setting times ranging from 18 min to 27 min than CPCC (39.15 ± 2.10 min) and MTA (123 ± 4.2 min). Metformin release increased proportionally with Met-PLGA content. hDPSCs exhibited good attachment and high viability on all materials over the evaluated period. In conclusion, Met-PLGA-CPCC provides fast-setting and favorable physico-mechanical properties, sustained metformin delivery, and excellent hDPSC compatibility. These properties support its potential as a bioactive direct pulp-capping material and as a versatile platform for regenerative applications. Full article

Sustainable development is crucial worldwide. Under the Paris Agreement, countries commit to Nationally Determined Contributions (NDCs) assessed every five years. China, a major contributor to global warming, has made significant efforts to reduce carbon emissions and achieve carbon neutrality, a key strategy for sustainable development. However, there is a lack of adequate attention to embodied emission reduction in rural residential construction, despite a surge in building to improve living standards. This paper evaluated the feasibility of applying a multi-ribbed composite wall structure (MRCWS) in rural China through a village service project. A full-scale shaking table test was conducted to study its seismic performance. Carbon emissions were analyzed using process-based life cycle assessment (P-LCA) and the emission-factor approach (EFA), while costs were estimated using life cycle costing (LCC) and the direct cost method (DCM). These analyses focused on sub-projects and specific structural members to validate the superiority of this prefabricated structure over common brick masonry. MRCWS blocks were prefabricated by mixing wheat straw with aerocrete, utilizing agricultural by-products from local farmlands, thus reducing both construction-related carbon emissions and agricultural waste treatment costs. Results show that this novel precast masonry structure exhibits strong seismic resistance, complying with fortification limitations. Its application can reduce embodied carbon emissions and costs by approximately 6% and 10%, respectively, during materialization phases compared to common brick masonry. This new prefabricated building product has significant potential for reducing carbon emissions and costs in rural housing construction while meeting seismic requirements. The recycling of agricultural waste highlights its adaptability, especially in rural areas. Full article

Given global efforts to promote sustainable energy transitions, this study investigates how the deployment of renewable energy technologies (RETs) relates to multidimensional societal welfare and provides empirical evidence on these linkages in Lithuania. The purpose of the study is to provide an integrated, Lithuania-specific assessment of how economic, social, and environmental determinants associated with RET deployment are related to multiple dimensions of societal welfare. Drawing on scientific literature, an integrated indicator framework is developed that links the economic, social, and environmental determinants of renewable energy technology (RET) deployment to six societal welfare dimensions, as defined by the Lithuanian Quality of Life Index. Using official Lithuanian statistics for 2020–2024, a standardized panel dataset is constructed and Pearson correlation analysis and multiple linear regression are applied using aggregated determinant categories, with model assumptions verified using the Breusch–Pagan and Durbin–Watson tests. Correlation results show very strong positive links between RET intensity indicators and key economic welfare measures (for example, wages, GDP per capita, foreign direct investment, disposable income), with absolute correlation coefficients typically between 0.90 and 0.99 (p < 0.05), and strong negative correlations between air-pollution indicators and GDP, income, FDI, and education (correlation coefficients between −0.96 and −0.90; p < 0.05). The results indicate that RET-related economic determinants have a statistically significant positive effect on the societal welfare dimensions of material living conditions; entrepreneurship/business competitiveness; and public infrastructure, living-environment quality/safety. Social factors also significantly support the societal welfare dimensions of entrepreneurship/business competitiveness and public infrastructure, living-environment quality/safety. In the retained regression models, explanatory power is very high (R² between 0.91 and 0.999), with positive and statistically significant coefficients for the economic determinant (regression coefficients between 0.43 and 0.96; p < 0.05) and negative, statistically significant coefficients for the environmental determinant in the entrepreneurship and public-infrastructure dimensions (regression coefficients between −1.13 and −1.51; p < 0.05). Environmental determinants are associated with lower air pollution but show negative effects on the societal welfare dimensions of entrepreneurship/business competitiveness and public infrastructure, living-environment quality/safety. Overall, the findings suggest that RET deployment is an important correlate of the economic aspects of societal welfare, while environmental and social dimensions display more complex, domain-specific impacts.

Regenerative medicine is increasingly leveraging the synergies between bioinspired conductive biomaterials and 3D/4D bioprinting to replicate the native electroactive and hierarchical microenvironments essential for functional tissue restoration. However, a critical gap remains in the intelligent integration of these technologies to achieve dynamic, responsive tissue regeneration. This review introduces a “bioinspired material–printing–function” triad framework to systematically synthesize recent advances in: (1) tunable conductive materials (polymers, carbon-based systems, metals, MXenes) designed to mimic the electrophysiological properties of native tissues; (2) advanced 3D/4D printing technologies (vat photopolymerization, extrusion, inkjet, and emerging modalities) enabling the fabrication of biomimetic architectures; and (3) functional applications in neural, cardiac, and musculoskeletal tissue engineering. We highlight how bioinspired conductive scaffolds enhance electrophysiological behaviors—emulating natural processes such as promoting axon regeneration cardiomyocyte synchronization, and osteogenic mineralization. Crucially, we identify multi-material 4D bioprinting as a transformative bioinspired approach to overcome conductivity–degradation trade-offs and enable shape-adaptive, smart scaffolds that dynamically respond to physiological cues, mirroring the adaptive nature of living tissues. This work provides the first roadmap toward intelligent electroactive regeneration, shifting the paradigm from static implants to dynamic, biomimetic bioelectronic microenvironments. Future translation will require leveraging AI-driven bioinspired design and organ-on-a-chip validation to address challenges in vascularization, biosafety, and clinical scalability. Full article

This paper assesses the use of ‘plastic age’ and ‘glass age’ terms, using a bibliometric approach to identify their proponents, purposes, and connections to debates in Anthropocene and heritage studies. This study explores how glass and plastic have been portrayed as age-defining materials and how this concept relates with what is expected to be preserved for future generations. Are these materials so ubiquitous that they become invisible? If visible, are they considered waste or heritage? Both materials appear in the Anthropocene discussion as stratigraphic indicators. The term ‘glass age’ is related with the marketing of glass (not only new glass formulations and new products, but also as an alternative to other more polluting materials), and the term ‘plastic age’ appears to be related to the multitude of plastics in our everyday lives and all the problems associated with their disposal. Although there are few examples of bibliometric research on glass and plastic as heritage, there is currently great investment in the study of glass and plastic from the perspective of conservation viability; this perspective needs to be promoted so that these materials can be included in heritage policies and museum collections as a reflection of today’s society.

Background and Objectives: Coracoid process (CP) fractures combined with acromioclavicular (AC) joint dislocation are extremely rare, and evidence guiding optimal surgical management remains limited. This retrospective, single-center case series study evaluated clinical and radiologic outcomes after simultaneous fixation of both lesions using a clavicular hook plate and a coracoid screw. Materials and Methods: We retrospectively reviewed 15 consecutive patients with Ogawa type I CP fractures combined with AC joint dislocation who underwent clavicular hook plate and coracoid screw fixation between March 2019 and May 2024. Clinical outcomes at final follow-up included shoulder range of motion (ROM), visual analog scale (VAS) for pain, and the Constant score. Radiologic outcomes included CP union confirmed by computed tomography (CT) and residual AC joint subluxation. Results: The cohort comprised 13 men and 2 women with a mean age of 55.2 years, and the mean final follow-up was 40.2 months. At final follow-up, mean ROM was 168° for forward elevation, 161° for abduction, and 69° for external rotation at the side, with internal rotation to L1. The mean VAS score was 0.4 and the mean Constant score was 97. CT-confirmed union of the CP fracture was achieved in all patients, and no residual AC joint subluxation was observed. All patients returned to sports and activities of daily living. Conclusions: In this series, simultaneous fixation using a clavicular hook plate and a coracoid screw provided reliable stabilization for CP fractures with AC joint dislocation, achieving consistent CP union, restoration of AC joint alignment, and favorable clinical outcomes. However, given the retrospective, non-comparative study design, these findings should be interpreted with caution, and further comparative studies are warranted. Full article

Objective: Additional preoperative risk factors may influence the prognosis of patients diagnosed with HBV. This study aims to compare the effects of cirrhosis patients with HBV with and without risk factors on post-transplant follow-ups and postoperative complications. Materials and Method: The study included patients with HBV who underwent living donor liver transplantation (LDLT) at Demiroğlu Bilim University, Şişli Liver Transplant Center, Istanbul, Türkiye, between 2004 and 2019. The data from 319 patients were retrospectively analyzed. Those without preoperative risk factors were classified as group 1 (n = 214), and those with risk factors were classified as group 2 (n = 105). These patients were compared in terms of complications during their postoperative follow-up. The Student’s t-test, ANOVA test, Mann–Whitney U test, Kruskal–Wallis test, chi-squared test, and Fisher’s exact test were used, and p < 0.05 was considered statistically significant. Results: When group 1 and group 2 were compared in terms of postoperative mortality, infections, bleeding complications, and biliary system complications, no statistically significant difference was found [(8.87% vs. 9.52% p = 0.62), (28.80% vs. 20.24%, p = 0.95), (6.10% vs. 8.70%, p = 0.35), (12.7% vs. 9.60% p = 0.19, respectively)]. Although bleeding complications were numerically found more frequent in patients with obesity, this difference did not reach statistical significance (23.02% vs. 6.10% p = 0.08). Conclusions: Obesity was not significantly associated with postoperative complications and may be influenced by accompanying comorbidities. Full article

This article examines Norah Hoult’s 1929 short story “Miss Jocelyn,” from her short story collection Poor Women!, as an intertextual response to James Joyce’s representation of single women in the short story “Eveline” included in his landmark 1914 collection Dubliners. Drawing on Katherine Fama and Jorie Lagerwey’s work on singlehood, I suggest that Hoult challenges the dichotomy of “married” versus “premarried” that Joyce critiques in “Eveline”. At the same time, Hoult’s portrait of Miss Jocelyn powerfully engages the material and social factors that so often condition single women’s lives. She considers not only Miss Joceyln’s awareness and loss of her former independence, but also the ways that ageism compromises her options and agency. While both stories examine the disempowerment of women, “Miss Joceyln” highlights the loss of agency, the financial dependency, and the societal dismissal to which celibate older women were often subject in early twentieth-century Ireland and Britain, thus treating celibacy as a “third space”—an option not proffered in Joyce’s work.

Thorium carbide (${\mathrm{ThC}}_{2\pm x}$) nano-structured thin disc-like pellets were produced from thoria nanoparticles (${\mathrm{ThO}}_2$-NP) and multi-walled carbon nanotubes (MWCNT). These composites are to be studied as a target material candidate for radioactive ion beam (RIB) production via nuclear reactions upon impact with high-energy proton beams on a stack of solid pellets. The ${\mathrm{ThO}}_2$-NP precursor was produced via precipitation of thorium oxalate from a thorium nitrate solution with oxalic acid and subsequent hydrothermal oxidation of the oxalate, creating the thoria nanoparticles. The ${\mathrm{ThO}}_2$-NP were then mixed with MWCNT in isopropyl alcohol and sonicated by two different methods to create a nanoparticle dispersion. This dispersion was then heated under medium vacuum to evaporate the solvent; the resulting powder was pressed into pellets and taken to an inert-atmosphere oven, where it was heated to 1650 °C and carbothermally reduced to ${\mathrm{ThC}}_{2\pm x}$. The resulting pellets were characterized via XRD, SEM-EDS, and Raman spectroscopy. The resulting thorium pellets exhibited, at most, trace levels of the oxide precursor. Furthermore, the nanotube structures were still present in the final product and are expected to contribute positively towards faster radioisotope release times by lowering isotope diffusion times, which is required for the efficient extraction of the shortest-lived (<1 s half-life) radioisotopes.

Introduction: Patients with colorectal cancer who undergo ileostomy surgery confront multifaceted challenges that significantly impact their daily lives and cause symptoms of anxiety and depression. The aim of this study was to explore the anxiety and depression experienced by colorectal cancer patients undergoing ileostomy with three assessments. Materials and Methods: This longitudinal study included 96 patients with newly diagnosed colorectal cancer who underwent scheduled ileostomy surgery at two public hospitals in Attica. The Hospital Anxiety and Depression Scale (HADs) was used, which included patients’ characteristics. Measurements were collected at three distinct time points: preoperatively (Time 1), postoperatively between the 12th and 14th day (Time 2), and after stoma closure, approximately one year later (Time 3). Statistical analysis was performed using the SPSS 26.0 statistical package and the statistical significance level was set at p < 0.05. Results: The proportion of participants reporting moderate levels of anxiety (scores 8–10) was 15.6% at Time 1, which increased to 27.1% at Time 2, and had a slight increase to 28.1% at Time 3. The increase was statistically significant between Time 1 and Time 2 and at Time 1 and Time 3 (p < 0.001). Regarding high levels of anxiety (scores >11), the percentage of affected individuals increased from 13.5% at Time 1 to 17.7% at Time 2 and reached 15.6% at Time 3. The comparison between Time 1 and Time 2 revealed a statistically significant increase (p = 0.016), while the subsequent decrease between Time 2 and Time 3 was not statistically significant (p = 0.508). In terms of depression, at Time 1, 84.4% of patients had low depression, which decreased significantly to 56.3% at Time 2 and 39.6% at Time 3 (p < 0.001 for all comparisons). The percentage of patients who were moderately depressed at Time 1 was 9.4%; this percentage increased significantly to 32.3% at Time 2 and remained high, reaching 29.2% at Time 3. Finally, the proportion of patients who had high levels of depression at Time 1 was 6.3%, a figure that rose to 11.5% and 31.3% for Time 2 and Time 3, respectively. Conclusions: Anxiety and depression experienced by colorectal cancer patients undergoing ileostomy surgery escalate postoperatively and remain at high levels after ileostomy closure. Understanding these mental health challenges is crucial for providing comprehensive patient care. Further research is needed on the early recognition and management of these emotional difficulties, which are key elements of holistic oncology care. Full article

Bacterial infections remain a major challenge to human health, especially in wound healing, where they can cause prolonged inflammation, delayed recovery, and severe complications. Current research is increasingly focused on developing innovative antimicrobial materials capable of overcoming the limitations of conventional antibiotics, whose effectiveness has declined due to the rise in bacterial resistance. Among the various alternatives, silver nanoparticles have gained particular attention for their broad-spectrum antibacterial properties and have already been successfully applied in the functionalization of commercial wound dressings. The aim of this study was to optimize the functionalization of commercial cotton gauzes based on in situ UV-assisted reduction of silver nanoparticles, reducing methanol usage and identifying the minimal silver nitrate precursor concentration to achieve antimicrobial efficacy while maintaining biocompatibility. Different precursor concentrations were then evaluated through cytocompatibility assays (MTT, Live/Dead, and scratch tests on fibroblasts) and antimicrobial analyses against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus (including an antibiotic-resistant strain), and Candida albicans. The results demonstrated that a 0.5% w/w silver nitrate concentration provided strong antimicrobial and antibiofilm activity without compromising textile properties or cytocompatibility. Furthermore, this optimized process reduced material waste, highlighting its potential for scalable production of antimicrobial wound dressings. Full article

Background/Objectives: Gastrointestinal and eating disorders are highly prevalent problems in children with Down syndrome (DS) and have a significant impact on their daily lives. It is important to investigate the bowel habits of children with DS, specifically the prevalence of functional constipation (FC), in order to develop practice guidelines for pediatricians that support diagnosis and treatment. Materials and Methods: This observational, analytical, and cross-sectional study was approved by the Ethics Committee and included 36 children with DS under pediatric outpatient follow-up at a university hospital. To assess bowel habits, an interview was held with the parents using the Rome IV criteria and the Bristol Stool Scale. The children were divided into two groups: those with and those without FC. Specific curves for individuals with DS were used for nutritional assessment. Results: The median age of the children was 46.6 months (5 to 144 months); a total of 80.5% of those included were eutrophic. The median age at initiation of toilet training was 36 months. Most children achieved bowel control when training started after 30 months of age. A total of 15 (41.7%) of the 36 children included were assigned to the group with FC, and 21 (58.3%) were assigned to the group without FC. The FC group had a lower frequency of bowel movements, hardened stools, pain during bowel movement, and used laxatives. According to the Rome IV criteria, the three most prevalent criteria were hard stools, large-volume stools, and painful bowel movements. Conclusions: Children with DS had a high prevalence of FC, and it was possible to identify an association between delayed sphincter training and FC. A care and monitoring protocol and flowchart are useful tools for the general pediatrician. Full article
