The aim of the evaluation was to gather information on parents’ experiences and attitudes towards the Irish National Newborn Bloodspot Screening Programme (NNBSP). An interviewer-administered survey was completed by 151 parents whose babies underwent newborn bloodspot screening (NBS) between 2023 and 2025 and for whom the screening result was normal. Results suggest that NBS is highly acceptable to parents, with 100% glad their baby underwent screening. The majority (95%) felt they were provided the information needed to understand the importance of NBS for their baby, and 93% are in favour of screening for more conditions. Positive aspects of NBS reported by parents included the following: blood sampling being undertaken in the home, the sample-taker being very nice and being advised in advance to keep the baby’s heel warm to ease the sampling process. Negative aspects of NBS reported included the following: having to return to the hospital for sampling, the baby becoming distressed, not receiving adequate information and not receiving the screening results. Parents were more likely to report negative experiences if the sample was not taken at home and if the sample was taken by a healthcare professional other than a public health nurse. Parents offered recommendations for improvements to the programme. This study provides important insights into parents’ experiences and attitudes towards NBS in Ireland. Full article

Marine sediments are a key component of aquatic ecosystems, linking diverse water uses, functions, and services. Chemical contamination of sediments is a global concern, with many jurisdictions striving to prevent future pollution and manage existing contamination. This study evaluates the contamination status of Rovinj’s coastal waters using an integrated approach that combines sediment and biota chemical analyses. Sediments were analyzed to assess long-term contaminant accumulation (D8.C1), while the Mediterranean mussel (Mytilus galloprovincialis) served as a bioindicator of bioavailable contaminants and their cumulative effects on marine habitats (D8.C2). Sediment samples were collected from five sites (S1–S5), and mussels were caged using Mussel Watch installations for approximately 120 days at a control site (Lim Bay) and within Rovinj harbor. Both matrices were analyzed for heavy metals (As, Cd, Cu, Cr, Hg, Ni, Pb, and Zn), polycyclic aromatic hydrocarbons (16 PAHs), and polychlorinated biphenyls (PCBs), following the EU Water Framework Directive. All sampled locations showed a reduction in sediment contamination relative to 2011 data, with most concentrations below ecotoxicological thresholds. Exceptions included elevated ΣPAH and PCB concentrations in the harbor (S1 = 3.18 mg/kg DW; 0.33 mg/kg DW) and marina (S2 = 3.64 mg/kg DW; 0.89 mg/kg DW), as well as Ni levels (S3 = 30 mg/kg DW; S4 = 34 mg/kg DW). Despite higher contaminant loads at some locations, mussel contaminant bioaccumulation remained limited, and their vitality and survival were only moderately affected in the harbor. Although localized increases in some contaminants were detected, all calculated Q_PECm values remained below 1.0, indicating no significant ecological risk. However, a moderate-to-high probability of toxic effects (P) may occur with long-term exposure for biota inhabiting harbor and marina areas. The results of this study demonstrate continued improvement in the environmental quality of Rovinj’s coastal waters compared to the previous decade. Full article

The transition to electric vehicles (EVs) is pivotal for decarbonizing transport, yet the siting of EV charging stations (EVCSs) can load radial distribution networks with higher losses and more pronounced voltage drops. This study formulates the joint siting and sizing of EVCSs and distributed generators (DGs) as a constrained optimization that minimizes real and reactive losses and voltage deviation with integer bus location decisions. A novel version of the Artificial Bee Colony (ABC) algorithm known as GBest–Lévy Adaptive Differential ABC (GLAD-ABC) is introduced, combining global best guidance, differential perturbations, adaptive step sizes, Lévy-flight scouting, and periodic local refinement for finding the global optimum solution and avoiding local optima. The optimizer is coupled with a backward–forward sweep load flow and a EVCS power demand model. Validation on the IEEE-33 and IEEE-69 feeders across multiple scenarios shows that EVCS-only deployment degrades network performance, whereas optimizing EVCS and DG allocation via GLAD-ABC markedly improves voltage profiles and reduces both real and reactive losses. The proposed optimizer shows superior performance compared with other optimization algorithms reported in the literature, delivering consistently lower active losses alongside fast, stable convergence, indicating strong suitability for utility planning in EV-rich grids.

Background/Objectives: Giant atrial chambers are rare but clinically important conditions, most often linked to rheumatic mitral valve disease, though they may also occur in congenital or other acquired disorders. Despite their low prevalence, they entail major hemodynamic, arrhythmogenic, and extracardiac risks. This study aimed to review recent evidence on giant atrial pathology—including giant left atrium (GLA), giant right atrium (GRA), and atrial appendage aneurysms—and to illustrate its relevance through cases of symptomatic extracardiac compression. Methods: A PubMed search on 15 September 2025 using “giant atrium” and limited to human, free full-text studies from the last 10 years yielded 93 results. After screening, 21 reports describing 24 cases were analyzed and compared with institutional experience. Results: GLA is most often defined by an anteroposterior diameter ≥6.5 cm or ≥8 cm, while criteria for GRA and appendage aneurysms remain inconsistent. Reported complications include atrial fibrillation, thromboembolism, and compression of mediastinal structures, with presentations such as dysphagia or airway obstruction. While valve surgery alone may suffice, many authors recommend concomitant atrial reduction or aneurysm resection in symptomatic patients. Conclusions: Giant atrial pathology, though uncommon, carries significant cardiac and extracardiac implications. Management should be individualized, and awareness of atypical manifestations is critical for timely diagnosis and treatment. Full article

Background: The GLA:D^® program is an evidence-based intervention widely used in Western countries to improve knee function and exercise adherence among individuals with osteoarthritis. However, its application in postoperative total knee arthroplasty (TKA) populations is limited, particularly in Asia. This study evaluated two modified GLA:D^® interventions tailored to the Korean clinical environment. Methods: Patients who underwent TKA participated in one of two programs. The GLA:D-M group received therapist-supervised neuromuscular training with structured progression. The GLA:D-C group received a modified GLA:D^® program with additional lower-limb strengthening, primarily conducted as home-based exercise. Outcomes at 3 and 6 months included functional performance, isokinetic strength, gait speed, and psychosocial measures. Statistical significance, minimal clinically important difference (MCID), and effect sizes were used to assess clinical relevance. Results: Both groups improved; however, recovery patterns differed. GLA:D-M demonstrated statistically significant (p < 0.05) and clinically meaningful improvements in functional and psychosocial outcomes, exceeding MCID thresholds with large effect sizes. GLA:D-C showed significant gains in lower-limb strength, but many changes did not meet the MCID and did not consistently translate into higher-level functional recovery. These findings suggest that supervised neuromuscular training may facilitate more comprehensive recovery than home-based strengthening alone. Conclusions: Adapting the GLA:D^® program for TKA patients in a Korean clinical setting was feasible and beneficial. Additionally, the delivery method, particularly therapist supervision, played a vital role in maximizing outcomes. Both program content and delivery format should be considered in rehabilitation models. Larger, long-term studies are warranted to confirm these findings and explore broader clinical applications.

The development of stable and efficient nanolubricants remains one of the main challenges in tribology due to particle agglomeration, poor long-term stability, and inconsistent frictional behavior under boundary lubrication. This study investigates the tribological performance of SAE 10W-40 engine oil enhanced with titanium dioxide (TiO₂) nanoparticles subjected to thermal treatments. TiO₂ powders (Degussa P25, ~30 nm) were calcined at 450 °C, 550 °C, 650 °C, and 750 °C, and incorporated into the base oil at a constant concentration of 0.05 wt%. Tribological tests were conducted using a four-ball tribometer under ASTM D4172 conditions (396 N, 1200 rpm, 30 min) at both ambient (23 °C) and elevated (75 °C) temperatures. The coefficient of friction (COF) and wear scar area (WSA) were measured, while the surface morphology was analyzed via 3D optical profilometry, SEM, and EDS. The results indicate that TiO₂ nanoparticles thermally treated at 550 °C offered the best tribological behavior, exhibiting the lowest COF and smallest WSA at both test temperatures. The improved performance is attributed to optimized crystalline structure and enhanced dispersion stability after calcination. Although no Ti-based tribofilm was detected, smoother wear scars suggest physical surface protection mechanisms, such as rolling and asperity smoothing. These findings highlight the critical influence of thermal treatment on nanoparticle effectiveness and demonstrate the potential of optimized nanoadditized lubricants for advanced friction and wear reduction under boundary lubrication conditions, providing practical guidance for developing next generation nanolubricants with improved durability and efficiency under boundary lubrication conditions.

Background: Total situs inversus (TSI) is a rare genetic anomaly, and approximately half of the affected individuals also have other associated cardiovascular anomalies. Thus, the concomitance of conduction and rhythm disturbances is seldom described in the medical literature. Methods: We searched the medical literature for similar cases published as full text, in English, on Clarivate, PubMed, and Google Scholar between 2016 and 2025. Results: We found 9 reports on TSI patients also having sick sinus syndrome (SSS) associated with rhythm disturbances, mainly atrial fibrillation, raising diagnostic and procedural challenges due to the anatomical anomalies requiring a peculiar approach. We describe the case of a 43-year-old woman diagnosed with TSI associated with ventricular arrhythmias in 2015 who experienced SSS requiring the implantation of a pacemaker during 10 years of follow-up but continued to have frequent episodes of nonsustained ventricular tachycardia (NSVT), raising multiple diagnoses and therapeutic challenges. After developing heart failure with preserved ejection fraction, she received guideline-adjusted treatment and, surprisingly, her clinical status improved, and NSVT diminished in frequency and then disappeared. Conclusions: Highlighting TSI′s clinical implications, often associated with other cardiovascular abnormalities, is important for an accurate diagnosis and adapted therapeutic management, considering the procedural challenges and potential complications.

Background/Objectives: C-reactive protein (CRP) is widely used as a marker of perioperative inflammation, but its predictive value for cardiac surgical outcomes remains uncertain. Obstructive sleep apnea (OSA), a prevalent and underrecognized comorbidity, may independently contribute to postoperative complications through non-inflammatory mechanisms. This study aimed to reevaluate the prognostic role of CRP and determine the clinical impact of OSA severity on postoperative recovery, focusing on new-onset atrial fibrillation (AF), prolonged intubation time, and postoperative CPAP/AIRVO use as indicators of respiratory burden. Methods: In this prospective cohort of 142 elective cardiac surgery patients, preoperative polysomnography and serial CRP measurements were obtained. Multivariable regression, mediation analysis, and propensity score matching (PSM) were performed to evaluate associations between OSA severity, CRP, and perioperative outcomes (AF, intubation time, CPAP/AIRVO use). Results: OSA severity independently predicted prolonged intubation (β = 1.74, p = 0.0019) and new-onset AF (β = 0.85, p = 0.004), even after excluding patients with preexisting arrhythmia. CRP showed poor discriminatory power as a standalone biomarker (AUC for IOT > 14 h = 0.445) and did not mediate OSA–outcome associations. However, CRP > 2.1 mg/dL doubled the odds of moderate-to-severe OSA (OR = 2.05, p = 0.041). A composite score integrating AHI, BMI, and postoperative CRP strongly correlated with postoperative respiratory support (p < 0.0001). Conclusions: OSA exerts a stronger and more consistent influence on perioperative outcomes than CRP, challenging reliance on CRP for risk stratification. Incorporating objective OSA screening and spirometry into preoperative assessment may enhance perioperative risk prediction and guide personalized management strategies. Full article

Glancing angle deposition (GLAD) is a unique physical vapor deposition technique to enable wafer-scale production of close-packed nanopillar arrays (NaPAs) made of a wide range of inorganic and organic materials and engineerable structures, offering great potential for advanced optoelectronic applications. By flexibly controlling substrate rotation during GLAD, this technique enables intricate sculpture of nanopillars in vertical/tilted column, helix, zigzag, and square spiral shapes or a combination of these shapes along the vertical growth axis. In particular, NaPAs exhibit unique engineerability in their material/structure-determined optical, electronic, chemical, mechanical, and morphological properties, making them versatile for significant applications in photovoltaics, photodetection, photocatalysis, and advanced displaying. In this review, we provide a comprehensive overview of recent advancements in optoelectronic applications of GLAD-fabricated NaPAs by exploring the relationship between structural features and device functionality. Additionally, we discuss the technical challenges associated with GLAD, such as scalability, material compatibility, and fabrication precision, and address prospects to produce next-generation optoelectronic devices.

Background/Objectives: Emerging evidence suggests the critical role of diet in shaping mental health outcomes, which are increasingly prevalent among children and adolescents worldwide. This study aims to investigate whether the dietary habits of children in the Italian multicenter Piccolipiù birth cohort at four years of age were associated with anxiety and depression symptoms. This analysis was conducted within the framework of the Global burden of disease Lifestyle And mental Disorder (GLAD) Project (DERR2-10.2196/65576). Methods: Data from 1726 children were analyzed. Emotional symptoms were assessed with the Child Behavior Checklist (CBCL), and diet was assessed using a food frequency questionnaire. Sociodemographic data, including per capita income, were also collected. Associations between food intake (grams per day) and clinical anxiety/depression (T-scores > 70) or total symptom scores were examined using univariate and multivariable logistic and robust linear regressions adjusted for sex and income. Results: In 1726 children (median age 4.4 years; 50% female), 3% exhibited clinical anxiety and 2% clinical depression. Higher grain intake was associated with increased odds of clinical anxiety (OR = 1.004; 95% CI: 1.001–1.007), while greater fish consumption reduced odds of clinical depression (OR = 0.946; 95% CI: 0.903–0.992). Vegetable intake was associated with lower anxiety and depression scores. Multivariable analyses confirmed that grain intake is positively associated with anxiety, while fish consumption is inversely associated with depression. Conclusions: Higher intake of vegetables, fruits, and fish may be associated with better emotional health in preschoolers, although effect sizes were modest. Early dietary interventions may offer a practical approach to improving children’s long-term mental health. Longitudinal studies are needed to confirm these associations and clarify underlying mechanisms. Full article

The response of titanium (Ti) thin films is closely related to their microstructure, which is extremely sensitive to the selected deposition parameters and geometrical configurations. The present study investigates the impact of geometrical factors on the growth of Ti thin films, focusing on how variations in growth geometry influence film microstructure, surface morphology, and corrosion resistance. Three Ti thin films were prepared using Glancing Angle Deposition (GLAD) in a custom-built DC reactive magnetron sputtering system. For the first sample, the target was positioned perpendicular to the substrate surface (α = 0°); for the second and third samples, the substrate holder was positioned at an angle of 85° regarding the target direction (α = 85°), incorporating a 180° azimuthal rotation for the last (to obtain a zigzag-like deposition). The thickness and morphological features of the thin films were investigated by SEM, while the surface morphology, specifically roughness, and crystallinity of the thin films were assessed by AFM and XRD, respectively. Continuous and alternating current techniques were used for electrochemical characterization of behavior in simulated body fluid. The obtained results show a clear tendency to an improvement in anticorrosion performances varying the nanoarchitecture of the films in comparison to the conventional-grown sample, with the inclined sample presenting a slight enhancement in corrosion resistance and the zigzag-grown sample having the best corrosion resistance properties of the three.

The electrical ventricular storm (VES) is defined as multiple sustained ventricular arrhythmias arising in a short time, often refractory to standard antiarrhythmic treatment. The three pillars of the physiopathogenesis of the VES are autonomic dysfunction, triggers, and an altered ventricular substrate. Incessant or highly recurrent ventricular arrhythmia impacts the hemodynamic status by worsening heart failure and increasing mortality. A stepwise, team-based, and tailored therapeutic approach is required to stop ventricular arrhythmia and regain the hemodynamic and electric stability of the patient. The authors focused on describing all currently available therapeutic approaches for VES, intending to establish the best VES therapeutic approaches. This process involves considering the patient’s specific condition, responses to previous treatments, and the potential risks and benefits of each approach. The options range from adjusting antiarrhythmic therapy to reprogramming of the ICD, sedation, epidural anaesthesia, stellate ganglia anaesthetic block, and the use of ECMO or left ventricular assist devices and radiofrequency catheter ablation. Particular attention is paid to the detailed management of genetic primary arrhythmia syndromes like long-QT syndrome, catecholaminergic polymorphic ventricular tachycardia, Brugada syndrome and Wolff–Parkinson–White syndrome, early repolarisation syndrome, right ventricular arrhythmogenic dysplasia, and idiopathic ventricular fibrillation. After overcoming the acute events of VES and obtaining hemodynamic stability, the treatment should shift toward an optimal balance of heart failure therapy, controlling the substrate by revascularisation procedures and resolving other pathology-generating ventricular arrhythmias. This article provides a comprehensive overview of ESV’s current management options using the most efficient strategies known to date. Full article

The Mo:BiVO₄/FeOOH photoelectrode was synthesized through the deposition of FeOOH onto the surface of the Mo:BiVO₄ photoelectrode. The composite photoelectrode demonstrated a photocurrent of 1.8 mA·cm⁻², which is three times greater than that observed for pure BiVO₄. Furthermore, the glycerol conversion rate was recorded at 79 μmol·cm⁻²·h⁻¹, approximately double that of pure BiVO₄, while the selectivity for glyceraldehyde reached 49%, also about twice that of pure BiVO₄. The incorporation of Mo has been shown to enhance the stability of the BiVO₄. Additionally, Mo doping improves the efficiency of electron-hole transport and increases the carrier concentration within the BiVO₄. This enhancement leads to a greater number of holes participating in the formation of iron oxyhydroxide (FeOOH), thereby stabilizing the FeOOH co-catalyst within the glycerol conversion system. The FeOOH co-catalyst facilitates the adsorption and oxidation of the primary hydroxyl group of glycerol, resulting in the cleavage of the C−H bond to generate a carbon radical (C). The interaction between the carbon radical and the hydroxyl group produces an intermediate, which subsequently dehydrates to form glyceraldehyde (GLAD). Full article

Glancing Angle Deposition (GLAD) has emerged as a versatile and powerful nanofabrication technique for developing next-generation gas sensors by enabling precise control over nanostructure geometry, porosity, and material composition. Through dynamic substrate tilting and rotation, GLAD facilitates the fabrication of highly porous, anisotropic nanostructures, such as aligned, tilted, zigzag, helical, and multilayered nanorods, with tunable surface area and diffusion pathways optimized for gas detection. This review provides a comprehensive synthesis of recent advances in GLAD-based gas sensor design, focusing on how structural engineering and material integration converge to enhance sensor performance. Key materials strategies include the construction of heterojunctions and core–shell architectures, controlled doping, and nanoparticle decoration using noble metals or metal oxides to amplify charge transfer, catalytic activity, and redox responsiveness. GLAD-fabricated nanostructures have been effectively deployed across multiple gas sensing modalities, including resistive, capacitive, piezoelectric, and optical platforms, where their high aspect ratios, tailored porosity, and defect-rich surfaces facilitate enhanced gas adsorption kinetics and efficient signal transduction. These devices exhibit high sensitivity and selectivity toward a range of analytes, including NO₂, CO, H₂S, and volatile organic compounds (VOCs), with detection limits often reaching the parts-per-billion level. Emerging innovations, such as photo-assisted sensing and integration with artificial intelligence for data analysis and pattern recognition, further extend the capabilities of GLAD-based systems for multifunctional, real-time, and adaptive sensing. Finally, current challenges and future research directions are discussed, emphasizing the promise of GLAD as a scalable platform for next-generation gas sensing technologies. Full article

Aqueous zinc ion batteries (AZIBs) have considerable potential for energy storage owing to their cost-effectiveness, safety, and environmental sustainability. However, dendrite formation, hydrogen evolution reaction (HER), and corrosion of the bare zinc (B-Zn) anode tremendously impact the performance degradation and premature failure of AZIBs. This study introduces a glancing angle deposition (GLAD) approach during the sputtering process to fabricate tellurium nanostructured (TeNS) at the zinc (Zn) anode to avoid the aforementioned issues with the B-Zn anode. Three different deposition times (5, 10, and 30 min) were used to prepare TeNS at the Zn anode. The morphology, crystallinity, composition, and wettability of the TeNSs were analyzed. The TeNSs served as hydrophilic sites and a protective layer, facilitating uniform Zn nucleation and plating while inhibiting dendrite formation and side reactions. Consequently, the symmetric cell with TeNS deposited on the Zn anode for 10 min (Te@Zn_10 min) demonstrated an enhanced cycling stability of 350 h, the lowest nucleation overpotential of 10.65 mV at a current density of 1 mA/cm², and an areal capacity of 0.5 mAh/cm². The observed enhancement in the cycling stability and reduction in the nucleation overpotential can be attributed to the optimal open area fraction of the TeNSs on the Zn surface, which promotes uniform Zn deposition while effectively suppressing side reactions.
