Published: June 2024

AbstractInvisible aligners have been widely used in orthodontic treatment but still present issues with plaque formation and oral mucosa abrasion, which can lead to complicated oral diseases. To address these issues, hydrophilic poly(sulfobetaine methacrylate) (polySBMA) coatings with lubricating, antifouling, and antiadhesive properties have been developed on the aligner materials (i.e., polyethylene terephthalate glycol, PETG) via a simple and feasible glycidyl methacrylate (GMA)‐assisted coating strategy. Poly(GMA‐co‐SBMA) is grafted onto the aminated PETG surface via the ring‐opening reaction of GMA (i.e., “grafting to” approach to obtain G‐co‐S coating), or a polySBMA layer is formed on the GMA‐grafted PETG surface via free radical polymerization (i.e., “grafting from” approach to obtain G‐g‐S coating). The G‐co‐S and G‐g‐S coatings significantly reduce the friction coefficient of PETG surface. Protein adsorption, bacterial adhesion, and biofilm formation on the G‐co‐S‐ and G‐g‐S‐coated surfaces are significantly inhibited. The performance of the coatings remains stable after storage in air or artificial saliva for 2 weeks. Both coatings demonstrate good biocompatibility in vitro and is not caused irritation to the oral mucosa of rats in vivo over 2 weeks. This study proposes a promising strategy for the development of invisible aligners with improved performance, which is beneficial for oral health treatment.

AbstractThe root nodules of actinorhizal plants are home to nitrogen‐fixing bacterial symbionts, known as Frankia, along with a small percentage of other microorganisms. These include fungal endophytes and non‐Frankia bacteria. The taxonomic and functional diversity of the microbial consortia within these root nodules is not well understood. In this study, we surveyed and analyzed the cultivable, non‐Frankia fungal and bacterial endophytes of root nodules from red and Sitka alder trees that grow together. We examined their taxonomic diversity, co‐occurrence, differences between hosts, and potential functional roles. For the first time, we are reporting numerous fungal endophytes of alder root nodules. These include Sporothrix guttuliformis, Fontanospora sp., Cadophora melinii, an unclassified Cadophora, Ilyonectria destructans, an unclassified Gibberella, Nectria ramulariae, an unclassified Trichoderma, Mycosphaerella tassiana, an unclassified Talaromyces, Coniochaeta sp., and Sistotrema brinkmanii. We are also reporting several bacterial genera for the first time: Collimonas, Psychrobacillus, and Phyllobacterium. Additionally, we are reporting the genus Serratia for the second time, with the first report having been recently published in 2023. Pseudomonas was the most frequently isolated bacterial genus and was found to co‐inhabit individual nodules with both fungi and bacteria. We found that the communities of fungal endophytes differed by host species, while the communities of bacterial endophytes did not.

AbstractBackgroundMultiple system atrophy is a neurodegenerative disease with α‐synuclein aggregation in glial cytoplasmic inclusions, leading to dysautonomia, parkinsonism, and cerebellar ataxia.ObjectiveThe aim of this study was to validate the accuracy of the International Parkinson and Movement Disorder Society Multiple System Atrophy clinical diagnostic criteria, particularly considering the impact of the newly introduced brain magnetic resonance imaging (MRI) markers.MethodsDiagnostic accuracy of the clinical diagnostic criteria for multiple system atrophy was estimated retrospectively in autopsy‐confirmed patients with multiple system atrophy, Parkinson's disease, progressive supranuclear palsy, and corticobasal degeneration.ResultsWe identified a total of 240 patients. Sensitivity of the clinically probable criteria was moderate at symptom onset but improved with disease duration (year 1: 9%, year 3: 39%, final ante mortem record: 77%), whereas their specificity remained consistently high (99%–100% throughout). Sensitivity of the clinically established criteria was low during the first 3 years (1%–9%), with mild improvement at the final ante mortem record (22%), whereas specificity remained high (99%–100% throughout). When MRI features were excluded from the clinically established criteria, their sensitivity increased considerably (year 1: 3%, year 3: 22%, final ante mortem record: 48%), and their specificity was not compromised (99%–100% throughout).ConclusionsThe International Parkinson and Movement Disorder Society multiple system atrophy diagnostic criteria showed consistently high specificity and low to moderate sensitivity throughout the disease course. The MRI markers for the clinically established criteria reduced their sensitivity without improving specificity. Combining clinically probable and clinically established criteria, but disregarding MRI features, yielded the best sensitivity with excellent specificity and may be most appropriate to select patients for therapeutic trials. © 2024 The Author(s).

Integrated unified phase‐field modeling (UPFM)
Authors: Zhao Yuhong 
Published: June 2024

AbstractFor a long time, the phase‐field method has been considered a mesoscale phenomenological method that lacks physical accuracy and is unable to be closely linked to the mechanical or functional properties of materials. Some misunderstandings existing in these viewpoints need to be clarified. Therefore, it is necessary to propose or adopt the perspective of “unified phase‐field modeling (UPFM)” to address these issues, which means that phase‐field modeling has multiple unified characteristics. Specifically, the phase‐field method is the perfect unity of thermodynamics and kinetics, the unity of multi‐scale models from micro‐ to meso and then to macro, the unity of internal or/and external driving energy with order parameters as field variables, the unity of multiple physical fields, and thus the unity of material composition design, process optimization, microstructure control, and performance prediction. It is precisely because the phase‐field approach has these unified characteristics that, after more than 40 years of development, it has been increasingly widely applied in materials science and engineering.
Twist sensor based on fiber Bragg grating fiber laser frequency splitting effect
Authors: Lu Peng , jing Genqiang , Luo Zhu , Wang Yiwu 
Published: June 2024

AbstractA twist sensor based on the frequency splitting effect of fiber Bragg grating laser is proposed and experimentally demonstrated. Laser longitudinal mode was split into two frequencies under the action of birefringence induced by fiber twist and by monitoring the periodical beat frequency response, the twist angle could be deduced. The experimental results show that the relationship between the fiber twist angle and the beat frequency is linear (linearity is more than 99%) when the twist angle is in the range of 10°–55°. Moreover, the wavelength drift caused by the temperature does not affect this linearity. Since the sensor is based on frequency rather than on the wavelength, its sensitivity is not limited to the resolution of the spectrometer, and has been improved to 31.59 MHz/rad (0.55 M/degree).
Three‐magnet‐ring quasi‐zero stiffness isolator for low‐frequency vibration isolation

Published: June 2024

AbstractA three‐magnet‐ring quasi‐zero stiffness (QZS‐TMR) isolator is designed to solve the problem of low‐frequency vibration isolation in the vertical direction of precision equipment. QZS‐TMR has both positive and negative stiffness structures. The positive stiffness structure consists of two mutually repelling magnetic rings and the negative stiffness structure consists of two magnetic rings nested within each other. By modulating the relative distance between positive and negative stiffness structures, the isolator can have QZS characteristics. Compared with other QZS isolators, the QZS‐TMR is compact and easy to manufacture. In addition, the working load of QZS‐TMR can be flexibly adjusted by varying the radial widths of the inner magnetic ring. In this paper, the static analysis of QZS‐TMR is carried out to guide the design, and the low‐frequency vibration isolation performance is studied. In addition, the experimental prototype of QZS‐TMR is designed and manufactured. The static and vibration isolation experiments are carried out on the prototype. The results show that the initial vibration isolation frequency of the experimental prototype is about 4 Hz. The results show an excellent low‐frequency vibration isolation effect, which is consistent with the theoretical research. This paper introduces a new approach to the design of the QZS isolator.

AbstractIntroductionBladder outflow obstruction (BOO) is a urethral resistance (UR) at a level above a clinically relevant threshold. UR is currently graded in terms of the existence and severity of the BOO based on maximum flowrate and associated detrusor pressure only. However, the pressure‐flow relation throughout the course of voiding includes additional information that may be relevant to identify the type of BOO. This study introduces a new method for the distinction between the provisionally called compressive and constrictive types of BOO and relates this classification to underlying patient and urodynamic differences between those BOO types.MethodsIn total, 593 high‐quality urodynamic pressure‐flow studies in men were included in this study. Constrictive BOO was identified if the difference Δp between the actual minimal urethral opening pressure (pmuo) and the expected pmuo according to the linearized passive urethral resistance relation (linPURR) nomogram was >25 cmH2O. Compressive BOO is identified in the complementary case where the pressure difference Δp ≤ 25 cmH2O. Differences in urodynamic parameters, patient age, and prostate size were explored.ResultsIn 81 (13.7%) of the cases, constrictive BOO was found. In these patients, the prostate size was significantly smaller when compared to patients diagnosed with compressive BOO, while displaying a significantly lower maximum flowrate, higher detrusor pressure at maximal flowrate and more postvoid residual (PVR).ConclusionThis study is an initial step in the validation of additional subtyping of BOO. We found significant differences in prostate size, severity of BOO, and PVR, between patients with compressive and constrictive BOO. Subtyping of voiding‐outflow dynamics may lead to more individualized management in patients with BOO.
Elastic sac to support oral feeding performance of preterm infants: Crossover randomized controlled study
Authors: Genç Canan , Gözen Duygu , Narter Fatma 
Published: June 2024

AbstractBackgroundSwaddling is recommended for preterm infants during feeding. Swaddling preterm infants with elastic cotton materials allows infants to easily stretch and move their extremities. This study aimed to assess the effect of bottlefeeding in a novel “elastic sac” on physiological parameters and feeding performance of preterm infants.MethodsA randomized controlled, crossover trial was conducted with total of 26 preterm infants at 26–36+6 weeks of gestation. Infants randomly assigned to group 1 (n = 13) were bottlefed in an elastic sac (researcher‐designed single‐piece pouch made of soft, elastic cotton) for the first feeding and in normal clothes for the next feeding. Infants randomly assigned to group 2 (n = 13) were fed first in normal clothes and then in the elastic sac. The physiological parameters and feeding performance of the infants were assessed during each feeding.ResultsPreterm infants fed in the elastic sac had lower heart rate and higher oxygen saturation during and after feeding than infants fed in normal clothes (P < 0.05). Although all values were within clinically normal ranges, the findings suggest that feeding preterm infants in the elastic sac had a favorable effect on physiological parameters compared with feeding in normal clothes. There was no significant difference in the infants' feeding performance (P > 0.05).ConclusionA semielevated right lateral position and flexed body posture are recommended while feeding preterm infants, which can be easily maintained using the elastic sac. Feeding preterm infants in an elastic sac may support physiologic stability during oral feeding.

Published: June 2024

AbstractThe presence and impact of malnutrition in adult hospitalized patients has been well documented by a significant body of literature. However, current malnutrition care practices often vary widely and frequently lack standardization. The Global Malnutrition Composite Score (GMCS), the first nutrition‐related electronic clinical quality measure, is intended to evaluate the quality of malnutrition care provided to inpatient adults. This measure aims to aid in standardizing malnutrition care through performance measurement. The four components of the measure (nutrition screening, nutrition assessment, malnutrition diagnosis, and nutrition care plans) follow the well‐established Nutrition Care Process and encourage the use of standardized terminology. Facilities with high‐performance scores on the GMCS are likely to experience improved outcomes associated with high‐quality malnutrition care.

AbstractAimsThis study aimed to evaluate the impacts of a single‐session group intervention for individuals with an eating disorder that involved collaborations between peer supporters, who had recovered from an eating disorder, and psychological professionals. We also compared intervention effects between in‐person and online settings.MethodsParticipants with an eating disorder were recruited through online platforms and public promotional materials. The inclusion criteria involved individuals who had current eating disorders and were willing to openly share their experiences during the session in which the Reflecting Team method was applied.ResultsThe analysis included 103 participants (75 in‐person and 28 online). We found significant time‐based effects (F(1, 101) = 70.390, p < 0.001, ηG2 = 0.083), which indicated that participants experienced reductions in feelings of isolation, hopelessness associated with their eating disorder, and belief in the incurability of their disorder following the group interventions. No significant differences were observed between in‐person or remote sessions (F(1, 101) = 0.087, p = 0.768, ηG2 = 0.001).ConclusionsOur findings suggest that peer supporters serve as a source of hope for individuals with eating disorders, even within group settings. Furthermore, the similar outcomes across in‐person and online sessions show the promise of remote group sessions as a novel means of support for individuals with eating disorders, regardless of their geographical location. However, future randomized controlled trials of continuous group therapy sessions are essential to confirm their effectiveness.

AbstractNanocomposites of poly(ε‐caprolactone) (PCL) reinforced by an organomodified beidellite (BDT) with 3% of cetyltrimethylammonium bromide (CTAB) (labeled PCL/3CTA‐BDT) were prepared by varying the content of filler (1, 2, 3, and 5 wt%). Their molecular dynamics were investigated by broadband dielectric spectroscopy at temperatures ranging from 0 to 40°C and a frequency window from 10−1 to 106 Hz. Three relaxation processes were detected for unfilled PCL: electrode polarization (EP), the Maxwell–Wagner–Sillars (MWS) polarization, and the α‐relaxation. The incorporation of the filler induced the emergence of a fourth process at high frequency of dipolar origin labeled as interfacial polarization (IP). Fitting the data with the Havriliak–Negami model as well as a study of the relaxation time variation with temperature demonstrated the noncooperative nature of the IP process. Activation energy and dielectric strength values demonstrated that the PCL/3CTA‐BDT with 3 wt% of filler showed a higher quality of dispersion and better interfacial features compared to those with other filler contents (2 and 5 wt%). This work highlights the challenges of dielectric green nanocomposites used for capacitors (storage energy) and cable/wire insulation.Highlights

Synthesis of chain‐end functionalized highly branched polyethylene waxes using sterically open α‐diimine Ni(II) catalysts
Authors: Chen Jianhai , Lu Zhou , Dai Shengyu 
Published: June 2024

AbstractOur previous research showed that bis(benzocyclopentyl) α‐diimine Pd(II) complexes can facilitate chain transfer and polar monomer insertion in ethylene (co)polymerization. In this study, we synthesized two bis(benzocyclopentyl) α‐diimine Ni(II) complexes with different backbones. The Ni(II) complexes exhibited high activities (0.63–7.23 × 106 g·mol−1 h−1) and produced low molecular weight (2.7–7.8 kg mol−1) polyethylene waxes with high branching densities (43–86/1000 C) in ethylene polymerization. The use of a catalyst with a butyl backbone resulted in polyethylene waxes with significantly higher molecular weights. The axial substituent restriction strategy employed in the nickel catalyst allows for a sterically open structure, reducing the molecular weight of the resulting polyethylene by over two orders of magnitude, compared to ethyl catalysts without axial restrictions. This enables the production of polyethylene wax grade products with improved properties. The branched polyethylene wax chain ends were found to be aryl‐functionalized according to NMR characterization analysis, while the double bonds were absent. Also, the choice of solvent affects the branching, molecular weight, and chain end composition of the polyethylene wax.

AbstractObjectiveClinical fear of cancer recurrence (FCR) was recently defined by a group of experts during a Delphi study. Five criteria were agreed upon, namely: (a) high levels of preoccupation, (b) high levels of worry, (c) that are persistent, (d) hypervigilance and hypersensitivity to physical sensations that e) may result in functional impairment. No existing instruments comprehensively capture all these criteria for clinical FCR.MethodsTo remedy this gap, a set of three patient‐reported outcome instruments including a one‐item screener, self‐report questionnaire, and semi‐structured clinical interview, named the Ottawa Clinical Fear of Recurrence instruments, were developed. To do so, the research team first conducted a literature review of potential items. Additional FCR experts discussed the content of the screener and interview. The self‐report's items were assessed for content validity by the same expert panel using Likert ratings and the Content Validity Index to narrow down the number of items. The three instruments were piloted with a group of cancer survivors to assess face validity following the European Organization for Research and Treatment of Cancer recommendations.ResultsThe literature review and content validity assessment led to a final draft pre‐pilot of 23 potential items for the self‐report questionnaire. The instruments were piloted. Pilot study participants suggested changing wording and response options (particularly for the self‐report) for greater clarity.ConclusionsBased on the feedback received, minor modifications were made, mostly for the self‐report. In general, content and face validity for the three instruments were good for both experts and cancer survivors.
