ObjectiveIdiopathic subglottic stenosis (iSGS) is a rare, recurrent, fibroinflammatory disease affecting the larynx and proximal trachea. Given it occurs primarily in adult females, estrogen is speculated to play a central pathophysiological role. This study aimed to evaluate relationships between estrogen exposure, disease progression, and recurrence.MethodsNorth American Airway Collaborative (NoAAC) data of adults with iSGS obstructive airway lesions, who underwent index endoscopic airway dilation, were used to identify associations between estrogen exposure, disease characteristics, and time to recurrence (TTR), and interventions were analyzed using Kruskal–Wallis test and Pearson coefficient. Cox proportional hazards regression models compared hazard ratios by estrogen exposure. Kaplan–Meier curves were plotted for TTR based on menopausal status.ResultsIn all, 533 females had complete estrogen data (33% premenopausal, 17% perimenopausal, 50% postmenopausal). Median estrogen exposure was 28 years. Overall, there was no dose–response relationship between estrogen exposure and disease recurrence. Premenopausal patients had significantly shorter time from symptom manifestation to diagnosis (1.17 vs. 1.42 years perimenopausal vs. 2.08 years postmenopausal, p < 0.001), shorter time from diagnosis to index endoscopic airway dilation (1.90 vs. 2.50 vs. 3.76 years, p = 0.005), and higher number of procedures (1.73 vs. 1.20 vs. 1.08 procedures, p < 0.001).ConclusionsWe demonstrate premenopausal patients may have a more aggressive disease variant than their peri‐ and postmenopausal counterparts. However, it is unclear as to whether this is related to reduced estrogen in the peri‐ and postmenopausal states or the age‐related physiology of wound healing and inflammation, regardless of estrogen.Level of Evidence3 Laryngoscope, 134:825–830, 2024
Impact of publisher's commercial or non‐profit orientation on editorial practices: Moving towards a more strategic approach to supporting editorial staff
Authors: Krapež Katarina 
Published: September 2023

AbstractThis study was guided by previous research highlighting the significance of journal publishers' commercial or non‐profit orientations in shaping academic editors' perspectives regarding the necessity of enhancing editorial and business practices. There is limited understanding of how the editor–publisher relationship varies based on publishers' commercial orientation. This study revealed five key factors influencing editors' attitudes towards how publishers strive to provide high‐quality publications: (i) availability of high‐quality publication services; (ii) sufficient technological support and access to visibility‐related data; (iii) accessible marketing and indexing services; (iv) access to continuous education for the editorial team; and (v) a balance between editorial autonomy and publisher support in managing the journal. The study indicated that editors partnering with commercial publishers tended to receive more extensive and advanced services, better technological support, and more training opportunities, contributing to the production of superior end products. However, working with commercial publishers resulted in the trade‐off of less editorial independence, which sometimes compromised editors' decision‐making ability and made them feel uncertain about their further involvement. The study's findings highlighted the importance of publishers adopting a more strategic approach to support their editorial staff, while considering the unique needs of each journal.
Revealing Mie Resonances with Enhanced and Suppressed Second‐Order Nonlinear Optical Responses in a Hexagonal‐Prism‐Like MoS2 Nanoparticle

Published: September 2023

AbstractTransition metal dichalcogenides (TMDC), such as molybdenum disulfide (MoS2), have attracted great interest owing to their excellent electronic and optical properties. Efficient second harmonic generation (SHG) has been successfully demonstrated in the MoS2 monolayer, in sharp contrast to the negligible SHG from the bulk material. Here, the nonlinear optical responses of hexagonal‐prism‐like MoS2 nanoparticles are investigated, which support Mie resonances in the near infrared spectral range. It is revealed that the Mie resonances of such a MoS2 nanoparticle can be clarified into two types, which exhibit enhanced and suppressed SHG. It is verified that the SHG from the MoS2 nanoparticle is strongly correlated with the electric field distribution at the optical resonance. For the electric quadrupole mode with an anti‐symmetric electric field distribution, the SHG is greatly suppressed. As a result, a nanohole appears in the emission pattern of the SHG from the MoS2 nanoparticle. In sharp contrast, the SHG from the electric dipole mode with a symmetric electric field distribution can be one order of magnitude stronger than that from a MoS2 monolayer. The findings open new horizons for manipulating the nonlinear optical responses of TMDC nanoparticles and pave the way for realizing photonic devices.

Published: September 2023

AbstractConventional wavefront sensors suffer from the fundamental limitation of the space‐bandwidth product and have a trade‐off between their spatial sampling interval and dynamic range. Here, nonlocal thin film optical filters with optimized angle‐ and polarization‐dependent responses are leveraged to circumvent the fundamental limitation, and a robust single‐shot wavefront sensing system with a small spatial sampling interval of 6.9 µm and a large angular dynamic range of 15° is realized. The system only requires inserting two multilayer dielectric filters, fabricated using a mature thin film deposition technique, into a conventional 4‐f imaging apparatus. The polarization‐sensitive nonlocal filters are used to map the 2D phase gradients of the incident light field to the intensity variation of the x‐ and y‐polarized light, respectively, thus enabling single‐shot 2D wavefront reconstruction from images taken by a polarization camera. Such a system may be used for a variety of applications, including high‐resolution image aberration correction, surface metrology, and quantitative phase imaging.
Phase Behaviors of Charged Macromolecules in Aqueous Solutions
Authors: Yang Yiming , Jia Di 
Published: September 2023

AbstractCompared to the charge–charge interaction, the role of the dipole‐dipole interaction has long been ignored in the phase behaviors of charged macromolecules in solutions. Charged macromolecules in solutions exhibit rich phase behaviors due to their complexity and they have been studied extensively. Phase separation can happen for charged macromolecules in the presence of monovalent salt, multivalent salt, and oppositely charged polymers, surfactants, etc., and for more advanced charged macromolecules such as polyzwitterions and polyampholytes, the phase diagram is even richer. In this perspective, the unacknowledged role of dipole‐dipole interaction in the phase behaviors of charged macromolecular solutions will be introduced. Dipolar polymers can form complex, self‐regulating structures which can be employed in various fields from drug‐delivery systems to next‐generation polymers. More importantly, it will shed light on how some of the life's basic and coherent structures such as biomolecular condensates and membrane‐less organelles are assembled and built by charged biomacromolecules such as DNA, RNA, and proteins.

Slowdown in total factor productivity of French private companies: Between microeconomic heterogeneity and inappropriate government policies
Authors: Bouattour Afef , Kalai Maha , Helali Kamel 
Published: September 2023

AbstractThis article aims to find an explanation for the slowdown in the total factor productivity (TFP) of private firms on the one hand, and on the other hand, to show the need for state intervention through government policies whose impacts on TFP were verified in the literature. In this paper, we examined the relationship between different government policies and TFP growth for 78 French firms covering the period 2005 to 2019. Firstly, this study showed that TFP varies considerably over time, suggesting that microeconomic factors may have an important impact on firms' TFP. Secondly, some of the government policies were favorable to TFP growth while others were rather hindering. Indeed, the positive impact of both public infrastructure spending and public subsidies to French firms shows that an expansionary fiscal policy would allow a recovery in TFP. On the other hand, taxes on imported products, the exchange rate and cost‐competitiveness ratio, with a negative impact, show that the competitiveness policies adopted are unfavorable to the resumption of TFP growth. Thirdly, it should be noted that operating, investment and R&D subsidies were channels for the effectiveness of French government policies. Finally, by taking into account a set of macroeconomic indicators, the study confirmed the positive impact of a favorable macroeconomic environment on the recovery of TFP.

ScopeQuinoa intake exerts hypoglycemic and hypolipidemic effects in animals and humans. Although peptides from quinoa inhibit key enzymes involved in glucose homeostasis in vitro, their in vivo antidiabetic properties have not been investigated.Methods and resultsThis study evaluated the effect of oral administration of a quinoa protein hydrolysate (QH) produced through enzymatic hydrolysis and fractionation by electrodialysis with ultrafiltration membrane (EDUF) (FQH) on the metabolic and pregnancy outcomes of Lepdb/+ pregnant mice, a preclinical model of gestational diabetes mellitus. The 4‐week pregestational consumption of 2.5 mg mL−1 of QH in water prevented glucose intolerance and improves hepatic insulin signaling in dams, also reducing fetal weights. Sequencing and bioinformatic analyses of the defatted FQH (FQHD) identified 11 peptides 6–10 amino acids long that aligned with the quinoa proteome and exhibited putative anti‐dipeptidyl peptidase‐4 (DPP‐IV) activity, confirmed in vitro in QH, FQH, and FDQH fractions. Peptides homologous to mouse and human proteins enriched for biological processes related to glucose metabolism are also identified.ConclusionProcessing of quinoa protein may be used to develop a safe and effective nutritional intervention to control glucose intolerance during pregnancy. Further studies are required to confirm if this nutritional intervention is applicable to pregnant women.
Image quality improvement in bowtie‐filter‐equipped cone‐beam CT using a dual‐domain neural network

Published: September 2023

AbstractBackgroundThe bowtie‐filter in cone‐beam CT (CBCT) causes spatially nonuniform x‐ray beam often leading to eclipse artifacts in the reconstructed image. The artifacts are further confounded by the patient scatter, which is therefore patient‐dependent as well as system‐specific.PurposeIn this study, we propose a dual‐domain network for reducing the bowtie‐filter‐induced artifacts in CBCT images.MethodsIn the projection domain, the network compensates for the filter‐induced beam‐hardening that are highly related to the eclipse artifacts. The output of the projection‐domain network was used for image reconstruction and the reconstructed images were fed into the image‐domain network. In the image domain, the network further reduces the remaining cupping artifacts that are associated with the scatter. A single image‐domain‐only network was also implemented for comparison.ResultsThe proposed approach successfully enhanced soft‐tissue contrast with much‐reduced image artifacts. In the numerical study, the proposed method decreased perceptual loss and root‐mean‐square‐error (RMSE) of the images by 84.5% and 84.9%, respectively, and increased the structure similarity index measure (SSIM) by 0.26 compared to the original input images on average. In the experimental study, the proposed method decreased perceptual loss and RMSE of the images by 87.2% and 92.1%, respectively, and increased SSIM by 0.58 compared to the original input images on average.ConclusionsWe have proposed a deep‐learning‐based dual‐domain framework to reduce the bowtie‐filter artifacts and to increase the soft‐tissue contrast in CBCT images. The performance of the proposed method has been successfully demonstrated in both numerical and experimental studies.

AbstractBackgroundSevere pneumonia in children accounts for a significant healthcare burden, involving prolonged hospitalization and increased risk of complications. The prognosis is closely related to the child's nutrition status. Anthropometric z scores are preferred to evaluate growth levels in children. This study aimed to investigate the association of anthropometric z scores with complications and length of hospital stay (LOS) in children with severe pneumonia.MethodsThis study included 361 hospitalized children aged 3 months to 5 years with severe pneumonia in Tianjin, China. Anthropometry was performed, and anthropometric z scores were calculated. Blood laboratory indices were assessed, and complications and LOS were recorded.ResultsThe average anthropometric z scores were −0.10 ± 1.15 (body mass index for age z score), 0.00 ± 0.97 (upper arm circumference for age z score [ACAZ]), and −0.14 ± 1.00 (triceps skinfold thickness for age z score [TSAZ]). The prevalence of complications was 73.96% (n = 267), including 82 children with only respiratory complications, 71 with only extrapulmonary complications, and 114 with both. After adjusting for confounding factors, compared with the noncomplication group, only the extrapulmonary complication group had a lower TSAZ (odds ratio [OR] = 0.597; 95% CI = 0.405–0.880; P < 0.05), whereas the respiratory and extrapulmonary complication group had a lower ACAZ (OR = 0.674; 95% CI = 0.469–0.969; P < 0.05) and TSAZ (OR = 0.573; 95% CI = 0.389–0.843; P < 0.05). ACAZ (β = −0.368; 95% CI = −0.720 to 0.016; P < 0.05) and TSAZ (β = −1.123; 95% CI = −1.470 to −0.777; P < 0.05) were negatively correlated with LOS.ConclusionACAZ and TSAZ were associated with complications and LOS of severe pneumonia in children aged 3 months to 5 years.

Authors: Puleio Alexa , Sheehan Amanda , Musen Gail , Patti Mary Elizabeth 
Published: September 2023

AbstractObjectiveBariatric surgery, a highly effective treatment for obesity and associated comorbidities, may improve cognition and brain volume in parallel with cardiometabolic function. However, some post‐bariatric individuals develop post‐bariatric hypoglycemia (PBH), which can be frequent and severe. The impact of recurrent hypoglycemia on cognition in PBH is unknown. The objective of this study was to determine whether individuals with PBH display reduced cognitive function compared with postsurgical counterparts without hypoglycemia.MethodsFourteen adults with a history of Roux‐en‐Y gastric bypass with hypoglycemia (PBH+, n = 7) or without PBH (PBH−, n = 7) completed assessments of memory, executive function, attention, and psychomotor speed.ResultsPBH+ individuals displayed significantly decreased performance in category fluency (p < 0.01), category switching (p < 0.01), and category switching accuracy (p < 0.01), compared with PBH− individuals. Performance in the first (p = 0.03) and third intervals (p = 0.045) of verbal fluency was significantly lower in PBH+ individuals versus PBH− individuals. All other assessments did not differ.ConclusionsPBH+ individuals may be at greater risk for cognitive impairment compared with PBH− individuals, as suggested by impaired semantic processing and cognitive flexibility, as well as greater difficulty initiating and sustaining word retrieval.
Maxillary Frenulum and “Lip Tie”: What Parents Understand
Authors: Bacon Beatrice R. , Carr Michele M. 
Published: September 2023

AbstractObjectiveTo determine the proportion of parents that have some knowledge of abnormal maxillary frenulum, or “lip tie,” and their sources of this information.Study DesignCross‐sectional study.SettingOtolaryngology clinic.MethodsConsecutive parents of children ≤12 years of age presenting at a pediatric otolaryngology clinic were surveyed to discover their understanding of “lip tie” in children. The survey included questions on the effects of “lip tie,” where they learned about “lip tie,” whether they thought their child had “lip tie,” whether they had a child undergo “lip tie” division, and how concerned they would be if they thought their child had “lip tie.” Information on participant demographics and social media was collected.ResultsOverall, 59.8% (193) of the 323 parents surveyed had heard of “lip tie”; of those, 17.1% (33) had a child that had undergone “lip tie” surgery. Most parents (91.2%, 176) thought “lip tie” caused breastfeeding problems. Roughly one‐quarter of parents (51 of 197 responses) rated their concern about “lip tie” as >8 of 10 on a Likert scale (mean, 5.7). The reported sources of “lip tie” information included lactation consultants (36.8%, 71), nurses (22.8%, 44), and pediatricians (31.6%, 61) as well as nonmedical sources, such as social media, family, and friends (68.4%, 132). Overall, 87% (282) of the 323 participants reported daily use of social media.ConclusionAlthough many parents are concerned about “lip tie,” much of their information on this condition comes from nonmedical sources. Social media would be a valuable platform to provide accurate information on “lip tie.”
Ductile damage and failure of thin sheet metals: New biaxial experiments and numerical simulations
Authors: Gerke Steffen , Valencia Fabuer R. , Brünig Michael 
Published: September 2023

AbstractThe paper deals with the ductile damage and failure behavior of thin sheet metals under proportional biaxial loading paths. A newly designed specimen is presented and an experimental series with different loading ratios is performed. Corresponding numerical simulations including plastic anisotropy reflect the stress state and enable the interpretation of the different damage mechanisms. Due to fabrication issues the specimen geometry for this class of materials has to get by without notches in thickness direction and consequently the new specimens pre‐define the localization by a series of holes. The strain fields at the specimen surface are evaluated by digital image correlation and the fracture surface is analyzed by scanning electron microscopy. The experimental and numerical methods described here provide a possibility for the targeted investigation of the ductile damage behavior of thin sheet metals under proportional loading.

AbstractThis study investigated the production, characterization, mechanical and tribological performance of surface‐modified cow bone powder‐reinforced composites. The primary goal was to increase the tribological and mechanical performance of sustainable and cleanly produced composite materials. It was determined that the surface‐modified bone powder reinforcement increased the mechanical, thermal, and wear resistance of the polymer. The best surface modification method was determined as silanization. It reduced the friction coefficient and weight loss by 16.60% and 40.0%, respectively, according to the main factor analysis. In addition, it increased the glass transition temperature by 45.54%, crystallization by 2.93%, hardness by 2.70%, and tensile strength by 9.26% compared to the unmodified bone powder reinforcement.Highlights
