Published: September 2024

AbstractThe periodontal tissue comprises alveolar bone, cementum, and periodontal ligament (PDL), forming a highly hierarchical architecture. Although current therapies could regenerate the hard tissue well, the simultaneous reconstruction of hard and soft tissue remains a great clinical challenge with the major difficulty in highly orientated PDL regeneration. Using the unidirectional freeze‐casting method and biomimetic mineralization technique, we construct a hierarchical bilayer scaffold with the aligned chitosan scaffold with ZIF‐8 resembling PDL, and intrafibrillarly mineralized collagen resembling alveolar bone. The hierarchical bilayer scaffold exhibits different geomorphic clues and chemical microenvironments to realize a perfect simulation of the natural periodontal hierarchical architecture. The aligned scaffold with ZIF‐8 could induce the fibrogenic differentiation of bone mesenchymal stromal cells (BMSCs), and the mineralized scaffold could induce osteogenic differentiation of BMSCs. The hierarchical bilayer scaffold could simulate periodontal complex tissue, exhibiting great promise for synchronized multi‐tissue regeneration of periodontal tissue.

AbstractBackgroundLaCuMnOx (LCMO) perovskite was designed as an effective catalyst to activate peroxydisulfate (PDS) to remove bisphenol A (BPA) in hypersaline wastewater.ResultsIn the LCMO/PDS system, BPA (10 mg/L) was removed completely and the mineralization degree reached 74.9% in the presence of 0.12 g/L catalyst and 1.2 mM PDS. The BPA removal efficiency was still almost 100% even after five cycles. Metal ion leakage also indicated the stability of the catalytic system. •OH, SO4•−, 1O2, and O2•− all contributed to BPA removal, and O2•− accounted for the greatest contribution. The presence of oxygen vacancies (Vo··) on the surface of the catalyst was important for PDS activation and the formation of active species. In addition, the system could still maintain outstanding performance even when [Cl−] and [SO42−] were 100 g/L. CO32− and HCO3− inhibited BPA degradation greatly, even at very low concentrations. The inhibitory effect was related to changes in the pH of the solution caused by the addition of CO32− and HCO3−. This effect could be eliminated by adjusting the pH.ConclusionThe system showed excellent catalytic performance, stability, and inorganic anion tolerance, indicating its potential for application in hypersaline wastewater treatment. © 2024 Society of Chemical Industry (SCI).

AbstractPurposeThis study aims to investigate the fetal Evans Index and establish a nomogram for fetuses without any additional fetal anomalies detected during the prenatal period.MethodsWe conducted our research at Ankara City Hospital, including 894 patients who were admitted and evaluated between gestational weeks 16–40. These patients had no fetal anomalies detected in subsequent gestational weeks. Descriptive data, such as age, gravidity, parity, and body mass index (BMI), were recorded. Gestational week and Evans Index (mean, median, standard deviation, minimum, maximum, and percentile) were also documented. The Evans index was calculated as the ratio between the maximal width of the frontal horns and the maximal width of the inner diameter of the cranium.ResultsWe evaluated 894 fetuses in pregnant women had no fetal anomalies detected throughout the pregnancy. The evaluation took place at different gestational weeks, and a nomogram for the Evans Index was created.ConclusionsIt is relevant for clinicians and researchers to be aware of the range of fetal Evans Index values across different gestational weeks as a prognostic criterion.

Authors: Nemmers Natasha , Lee Jeong Eun 
Published: September 2024

AbstractLater life disability poses a significant public health challenge, and while research often concentrates on physical limitations, understanding the full spectrum of disability requires a comprehensive approach. This study employs latent profile analysis (LPA), a statistical technique that identifies underlying subgroups or profiles within a larger population based on patterns of responses to multiple indicators, to classify disability. We examined one wave of existing panel data from 414 participants aged 72–106 living in retirement communities. We focus on the following disability indicators: basic and instrumental activities of daily living; physical, cognitive, and sensory impairments; and participation restrictions. Three distinct profiles emerged. The largest group (58%), “Low Disability,” exhibited minimal disability across all domains and superior psychological well‐being. The second group (38%) experienced “High Physical and Functional Disability,” with a higher prevalence among older, unmarried women. The smallest group (4%) displayed “High Cognitive‐Sensory‐Functional Disability,” marked by extensive cognitive impairment and the highest functional and sensory limitations, prevalent in advanced age with poorer psychological outcomes of all profiles. Notably, participation restrictions showed minimal variation across disability profiles. The findings emphasize the need for a data‐driven policy framework addressing disability profiles. Efficient resource allocation and targeted support are crucial, and prevention strategies should proactively address individuals at risk of transitioning into higher‐multidomain disability profile membership. Given the connection between disability and mental health, addressing these concerns can enhance overall health and well‐being. Future research should explore changes in disability group membership over time in diversified samples.

AbstractObjectives/HypothesisSocioeconomics and demographics have been shown to be determinates of healthcare in specialty clinics, in which thorough research is lacking in the setting of the United States clinical sphere. We set out to determine the impact of socioeconomic and demographic factors on patient preparedness in an otolaryngologic clinic as to highlight the need for awareness in this aspect of disparate and delayed clinical care.Study DesignRetrospective chart review.MethodsA chart review was conducted of 482 patients who visited our otolaryngology clinic between June 1, 2020 and June 1, 2023. Demographic data including marital status, gender, age, zip code, and race was collected.ResultsOur study found several interesting points of significance. Marital status was a significant determinant of whether patients had missing labs and/or imaging (p = .001). Age was a significant determinant of patients having their imaging (p < .0001). Patients were more likely to have all their labs and imaging at a follow‐up appointment compared to an initial appointment (p < .0001). Finally, a patient's zip code was found to be a significant determinant of whether a patient no‐showed an appointment or arrived with all their needed imaging and labs (p = .004).ConclusionsHaving the needed labs and imaging for a clinical visit is vital to providing timely and well‐informed care for all patients. This study highlighted several potential determinates of missing labs and imaging. Elderly patients were less likely to have imaging, which may be attributed to transportation issues and a weaker support system. Individuals who were married were more likely to have their imaging. Married individuals may have a stronger support system, where their spouses can provide transportation and reminders for appointments. Finally, the significance of zip code highlights the role transportation distance and living in an underserved area may have on patients being able to go to their appointments or obtain their needed imaging.Level of Evidence4

AbstractThe micro‐ring resonator (MRR) is a crucial element in integrated photonics. It allows for the realization of various optical devices, including integrated filters, modulators, micro‐ring laser cavities, detectors, optical logic switches, and nonlinear optical devices. The development of integrated photonics has enabled the integration of these devices with other components into a photonic chip to perform specific functions. For instance, widely tunable MRR‐based lasers have been integrated with optical phased arrays (OPAs), detectors, and other elements to form a fully integrated LiDAR engine. Advances in nanofabrication have facilitated the miniaturization of nanophotonic phased arrays and on‐chip lasers. MRR‐based integrated external cavity lasers (ECLs) and integrated optical frequency combs (OFCs) have significantly enhanced the scanning and detection capabilities of LiDAR recently. Additionally, their size and power consumption have been continuously reduced, rendering them suitable for chip‐scale integration. This paper systematically reviews the major advancements of MRR‐based integrated lasers for chip‐scale LiDAR.

AbstractUltrasound and photoacoustic imaging are important imaging modalities with significant applications in clinical diagnosis and biomedical research. However, current capacitive and piezoelectric ultrasound detectors face challenges related to sensitivity and bandwidth, particularly at higher frequencies. These challenges can hinder their ability to achieve high spatial resolution and deep penetration for imaging purposes. Optical ultrasound sensors offer high sensitivity and show great potential for developing ultrasound/photoacoustic imaging systems. Among all methods of optical ultrasound detection, integrated photonics, with its superior advantages in miniaturization, sensitivity, and integration capability with electronics, could be next‐generation photoacoustic/ultrasound imaging technology. This review explores the device structure designs and applications of ultrasound/photoacoustic sensing based on integrated photonics, analyzes their performance metrics as ultrasound detectors, and discusses some perspectives on future developments and trends in this field.

Published: September 2024

AbstractPurposeTo develop a generic radial sampling scheme that combines the advantages of golden ratio sampling with simplicity of equidistant angular patterns. The irrational angle between consecutive spokes in golden ratio‐based sampling schemes enables a flexible retrospective choice of temporal resolution, while preserving good coverage of k‐space for each individual bin. Nevertheless, irrational increments prohibit precomputation of the point‐spread function (PSF), can lead to numerical problems, and require more complex processing steps. To avoid these problems, a new sampling scheme based on a rational approximation of golden angles (RAGA) is developed.MethodsThe theoretical properties of RAGA sampling are mathematically derived. Sidelobe‐to‐peak ratios (SPR) are numerically computed and compared to the corresponding golden ratio sampling schemes. The sampling scheme is implemented in the BART toolbox and in a radial gradient‐echo sequence. Feasibility is shown for quantitative imaging in a phantom and a cardiac scan of a healthy volunteer.ResultsRAGA sampling can accurately approximate golden ratio sampling and has almost identical PSF and SPR. In contrast to golden ratio sampling, each frame can be reconstructed with the same equidistant trajectory using different sampling masks, and the angle of each acquired spoke can be encoded as a small index, which simplifies processing of the acquired data.ConclusionRAGA sampling provides the advantages of golden ratio sampling while simplifying data processing, rendering it a valuable tool for dynamic and quantitative MRI.

AbstractIntroduction/AimsNusinersen intrathecal administration can be challenging in spinal muscular atrophy (SMA) adults. We aimed to determine if the ultrasound (US)‐assistance reduces the number of needle attempts and needle redirections needed for intrathecal drug administration and its impact on the procedure time, the incidence of adverse events (AEs), and patient satisfaction in these patients.MethodsFifty‐eight patients aged 18 years and older scheduled for intrathecal nusinersen injection were enrolled and randomized (1:1 ratio) into Group 1 (nusinersen infusion with US‐assisted technique) or Group 2 (nusinersen infusion with landmark‐based technique). The number of attempts, number of redirections, periprocedural time, AEs and patient satisfaction were reported. Continuous variables were compared with the Student t‐test or Wilcoxon rank sum test. Categorical variables were evaluated with the Chi‐square test or Fisher's exact test in case of expected frequencies <5. The p‐values <.05 were considered statistically significant.ResultsThere were no statistical differences in the number of attempts, AEs, or patient satisfaction between the two groups. The number of needle redirections was significantly lower in the ultrasound group versus landmark‐based group (p < .05) in both the overall group of patients and in the subgroup with difficult spines. The periprocedural time was about 40 seconds longer in US‐group versus landmark‐based group (p < .05).DiscussionIn SMA adults, US assistance reduces the number of needle redirections needed for intrathecal drug administration. These results suggest that the US assistance may be advantageous for nusinersen therapy to reduce the therapeutic burden of intrathecal infusion.

AbstractThe one parameter conjugate gradient method by Hager and Zhang (Pac J Optim, 2(1):35–58, 2006) represents a family of descent iterative methods for solving large‐scale minimization problems. The nonnegative parameter of the scheme determines the weight of conjugacy and descent, and by extension, the numerical performance of the method. The scheme, however, does not converge globally for general nonlinear functions, and when the parameter approaches 0, the scheme reduces to the conjugate gradient method by Hestenes and Stiefel (J Res Nat Bur Stand, 49:409–436, 1952), which in practical sense does not perform well due to the jamming phenomenon. By carrying out eigenvalue analysis of an adaptive two parameter Hager–Zhang type method, a new scheme is presented for system of monotone nonlinear equations with its application in compressed sensing. The proposed scheme was inspired by nice attributes of the Hager–Zhang method and the various schemes designed with double parameters. The scheme is also applicable to nonsmooth nonlinear problems. Using fundamental assumptions, analysis of the global convergence of the scheme is conducted and preliminary report of numerical experiments carried out with the scheme and some recent methods indicate that the scheme is promising.

AbstractObjectiveThe aim of this study was to assess the utility of ultrasound (US) imaging for diagnosis of abnormal tracheal morphology, such as tracheal cartilaginous sleeves (TCS), in patients with syndromic craniosynostosis (SC).Study DesignAge‐matched cohort study.SettingTertiary pediatric hospital.MethodsTwo age‐matched cohorts were identified: patients with SC and known TCS based upon airway endoscopy and normal controls without tracheal pathology. Enrolled patients underwent awake US of the neck which were randomized and reviewed by blinded pediatric radiologists and rated on presence or absence of normal tracheal cartilage morphology and visualization or nonvisualization of a tracheostomy tube. Fisher's exact test was used to assess pooled data. Fleiss' Kappa (κ) was calculated to assess inter‐rater reliability.ResultsTen patients were included in each cohort. Control patients were gender and age‐matched to TCS patients with a mean difference of 3.7 months (±3.9 months). Across all raters, cartilage type was correctly identified in 93% (95% confidence interval [CI]: 84%‐98%) and tracheostomy visualization in 97% (95% CI: 89%‐99%). The sensitivity and specificity for detection of abnormal cartilage pathology was 87% and 100%, respectively. Inter‐rater reliability for cartilage assessment was κ = 0.88 (95% CI: 0.67‐1.00, P < .05) and 0.83 (95% CI: 0.58‐1.00, P < .05) for tracheostomy presence.ConclusionThis study demonstrated that tracheal US is a feasible, accurate screening tool for TCS, and can be successfully performed non‐sedated in patients up to 18 years of age, both with and without tracheostomy tubes in place.

AbstractThe efficiency of a staged photocatalytic reactor prototype was evaluated on a semi‐pilot scale with the removal of acetaminophen, for which anatase particles were synthesized by Sol‐Gel and impregnated on rectangular plates of clay. X‐ray diffraction and Energy Dispersive X‐ray Fluorescence patterns show that the final composite is made up of Al2O3 (14 %), SiO2 (41 %), CaO (3 %) TiO2 (34 %), and Fe2O3 (7 %). The impregnation method favors the dispersion of Anatase on the surface of the adsorbent. TiO2‐Anatase/Clay, classified as a macro‐porous solid with H3‐type hysteresis loops by N2 physisorption. Adsorption processes are improved when using TiO2‐Anatase/Clay compared to using TiO2‐Anatase. The external mass transfer has a greater influence on the removal rate. The dimensionless parameters of the Biot number indicate there are no limitations due to the diffusive effect on the interior of the particle. The evaluation of the kinetic data under the Langmuir‐Hinshelwood equation shows a decrease in efficiency as the initial concentration increases. The acetaminophen molecule shows destabilization in the structure of the aromatic ring with a visible decrease in the signals of this functional group evaluated by High‐Performance Liquid Chromatography and Raman Spectroscopy.

Published: September 2024

AbstractComponents for timber constructions are usually based on simple geometrical shapes. In the production, bifurcated or curved components of the tree crown remain unused. Recently, building botany has evolved as a new discipline of living construction design. Therefore, trees are lead in the right shape to join as a load‐bearing structure interconnected with conventional parts. For the structural analysis, geometric features such as curvature or bifurcations exhibit unique static capabilities. It is crucial to transfer these geometries into the calculation model accurately. The structure can be depicted through three‐dimensional scanning techniques. A fundamental model (point cloud) is created in this process. This is the base for a Non‐uniform rational B‐spline (NURBS) model, existing as a 2D surface within a 3D space. Using the novel generalized scaled boundary isogeometric analysis (GSBIGA)‐approach, numerical disadvantages of conventional scaled boundary methods can be reduced. This method employs a scaling center line instead of a scaling center point. A growth simulation is used to describe the leading process. The present approach is based on an isotropic growth model applied to wooden growth applications. Therefore, the deformation gradient is split multiplicatively into an elastic and a growth part. The formulation for modeling volumetric growth is located on the kinematic level.
