AbstractIntroductionSupportive adults are a critical component of effective out‐of‐school time (OST) youth programs, yet the short‐term dynamics that underlie their role are poorly understood. Within GripTape, a US‐wide self‐driven learning program, we examined if interactions with program‐assigned adults (i.e., Champions) correspond with youths' daily psychosocial functioning (i.e., sense of purpose, self‐concept clarity, and self‐esteem).MethodParticipants were 204 North American adolescents (M [SD] = 16.42 [1.18] years; female = 70.1%, male = 25.0%) enrolled in GripTape, a remote OST program that empowers under‐resourced teens to pursue their passions for ~10 weeks. During enrollment, youth are given autonomy to structure their learning goals and methods to best match their needs; a stipend of up to 500 USD; and an adult Champion to act as a touchpoint. Data collection consisted of a baseline survey before the program launch and a 5‐min survey on each day of enrollment.ResultsAcross ~70 days, we found that youth reported greater psychosocial functioning on days they reported interacting with their Champion. After controlling for same‐day psychosocial functioning, we failed to find evidence that Champion interactions predicted youths' next‐day psychosocial functioning.ConclusionIn addition to being among the first studies to investigate the daily benefits of youth‐adult interactions within OST programming, this study documents the short‐term incremental change that may underlie previous work on OST program outcomes.

AbstractObesity is frequently a significant risk factor for multiple obesity‐associated diseases that have been increasing in prevalence worldwide. Anthropometric data such as body mass index, fat, and fat mass values are assessed for obesity. Therefore, we aimed to propose two Fourier transform infrared (FT‐IR) spectral regions, 800–1800 cm−1 and 2700–3000 cm−1, as sensitive potential band assignments for obesity‐related biochemical changes. A total of 134 obese (n = 89) and controls (n = 45) biochemical characteristics and clinical parameters indicative of obesity were evaluated. The FT‐IR spectra of dried blood serum were measured. Anthropometric data of the obese have the highest body mass index, %fat, and fat mass values compared to the healthy group (p < 0.01). Also, the triglyceride and high‐density lipoprotein cholesterol levels were higher than in healthy subjects (p < 0.01). Principal component analysis (PCA) technique successfully distinguished obese and control groups in the fingerprint, accounting for 98.5% and 99.9% of the total variability (800–1800 cm−1) and lipids (2700–3000 cm−1) regions presented as 2D and 3D score plots. The loading results indicated that peaks corresponding to phosphonate groups, glucose, amide I, and lipid groups were shifted in the obese group, indicating their potential as biomarkers of obesity. This study suggests that FTIR analysis based on PCA can provide a detailed and reliable method for the analysis of blood serum in obese patients.

Published: March 2023

AbstractHydrogel injection molding is a biofabrication method that is useful for the rapid generation of complex cell‐laden hydrogel geometries, with potential utility in biomanufacturing products for tissue engineering applications. Hydrogel injection molding requires that hydrogel polymers have sufficiently delayed crosslinking times to enable injection and molding prior to gelation. In this work, we explore the feasibility of injection molding synthetic poly(ethylene) glycol (PEG)‐based hydrogels functionalized with strain promoted azide‐alkyne cycloaddition click chemistry functional groups. We evaluate the mechanical properties of a PEG‐based hydrogel library, including time to gelation and successful generation of complex geometries via injection molding. We evaluate the binding and retention of adhesive ligand RGD within the library matrices and characterize the viability and function of encapsulated cells. This work demonstrates the feasibility of injection molding synthetic PEG‐based hydrogels for tissue engineering applications, with potential utility in the clinic and biomanufacturing.
Low‐fit cause‐related marketing: When and why do consumers respond positively?
Authors: DeMotta Yoshiko , Janssen Catherine , Sen Sankar 
Published: March 2023

AbstractThis paper examines when and why consumers are likely to support low‐fit cause‐related marketing (CM) initiatives. Through six studies, we demonstrate that when consumers think more holistically rather than analytically, they are likely to respond as positively to low‐fit CM initiatives as high‐fit ones. This effect occurs because holistic thinkers focus not only on the company and its characteristics but also on the perceived need of the cause beneficiaries, making them more likely to perceive the corporate motives to be public‐serving, producing more favorable evaluations of the company. Dispositional skepticism toward corporate social responsibility (CSR) acts as a boundary condition of this effect.

AbstractSevere fever with thrombocytopenia syndrome (SFTS) is a tick‐borne emerging infectious disease with an increasingly global concern. Sex difference in infectious diseases is an important public health problem. A comparative study on sex differences in SFTS incidence and fatality was conducted using all laboratory‐confirmed cases in mainland China during 2010−2018. Females had significantly higher average annual incidence rate (AAIR) with a risk ratio (RR) of 1.17 (95% confidence interval [CI] 1.11–1.22; p ˂ 0.0001), but significantly lower‐case fatality rate (CFR) with an odd ratio of 0.73 (95% CI 0.61–0.87; p = 0.001). The significant differences in AAIR and CFR were observed in age groups of 40–69 and 60–69 years, respectively (both p < 0.05). There was a rising incidence and declining CFR along with epidemic years. After adjusting for age, temporal and spatial distribution, agricultural setting and onset‐to‐diagnosis interval, the female‐to‐male difference in either AAIR or CFR remained significant. The underlying biological mechanisms of the sex‐based differences that the females are more prone to get the disease, but less likely for a fatal outcome deserve further investigations.

AbstractThe present study aimed to examine a weakly electric fish Gnathonemus petersii (G. petersii) as a candidate model organism of glutamatergic theory of schizophrenia. The idea of G. petersii elevating the modeling of schizophrenia symptoms is based on the fish's electrolocation and electrocommunication abilities. Fish were exposed to the NMDA antagonist ketamine in two distinct series differing in the dose of ketamine. The main finding revealed ketamine‐induced disruption of the relationship between electric signaling and behavior indicating impairment of fish navigation. Moreover, lower doses of ketamine significantly increased locomotion and erratic movement and higher doses of ketamine reduced the number of electric organ discharges indicating successful induction of positive schizophrenia‐like symptoms and disruption of fish navigation. Additionally, a low dose of haloperidol was used to test the normalization of the positive symptoms to suggest a predictive validity of the model. However, although successfully induced, positive symptoms were not normalized using the low dose of haloperidol; hence, more doses of the typical antipsychotic haloperidol and probably also of a representative of atypical antipsychotic drugs need to be examined to confirm the predictive validity of the model.

ObjectiveCommonly used endoscopic grading scales, such as the nasal polyp scale, inadequately describe the degree of polyposis found postoperatively in the paranasal sinus cavities. The purpose of this study was to create a novel grading system that more accurately characterizes polyp recurrence in postoperative sinus cavities, the Postoperative Polyp Scale (POPS).MethodsA modified Delphi method was utilized to establish the POPS using consensus opinion among 13 general otolaryngologists, rhinologists, and allergists. Postoperative endoscopy videos from 50 patients with chronic rhinosinusitis with nasal polyps were reviewed by 7 fellowship‐trained rhinologists and scored according to the POPS. Videos were rated again 1 month later by the same reviewers, and scores were assessed for test–retest and inter‐rater reliability.ResultsOverall inter‐rater reliability for the first and second reviews of the 52 videos was Kf = 0.49 (95% CI 0.42–0.57) and Kf = 0.50 (95% CI 0.42–0.57) for the POPS. Intra‐rater reliability showed near‐perfect test–retest reliability for the POPS with Kf = 0.80 (95% CI 0.76–0.84).ConclusionThe POPS is an easy‐to‐use, reliable, and novel objective endoscopic grading scale that more accurately describes polyp recurrence in the postoperative state which will be useful in the future for measuring the efficacy of various medical and surgical interventions.Level of Evidence5 Laryngoscope, 133:2885–2890, 2023

ObjectivesCompared to adult patients undergoing thyroid surgery, pediatric patients have higher rates of hypoparathyroidism often related to parathyroid gland (PG) inadvertent injury or devascularization. Previous studies have shown that near‐infrared‐autofluorescence (NIRAF) can be reliably used intraoperatively for label‐free parathyroid identification, but all prior studies have been performed in adult patients. In this study, we assess the utility and accuracy of NIRAF with a fiber‐optic probe‐based system to identify PGs in pediatric patients undergoing thyroidectomy or parathyroidectomy.MethodsAll pediatric patients (under 18 years of age) undergoing thyroidectomy or parathyroidectomy were enrolled in this IRB‐approved study. The surgeon's visual assessment of tissues was first noted and the surgeon's confidence level in the tissue identified was recorded. A fiber‐optic probe was then used to illuminate tissues‐of‐interest with a wavelength of 785 nm and resulting NIRAF intensities from these tissues were measured while the surgeon was blinded to results.ResultsNIRAF intensities were measured intraoperatively in 19 pediatric patients. Normalized NIRAF intensities for PGs (3.63 ± 2.47) were significantly higher than that of thyroid (0.99 ± 0.36, p < 0.001) and other surrounding soft tissues (0.86 ± 0.40, p < 0.001). Based on the PG identification ratio threshold of 1.2, NIRAF yielded a detection rate of 95.8% (46/48 pediatric PGs).ConclusionOur findings indicate that NIRAF detection can potentially be a valuable and non‐invasive technique to identify PGs during neck operations in the pediatric population. To our knowledge, this is the first study in children to assess the accuracy of probe‐based NIRAF detection for intraoperative parathyroid identification.Level of EvidenceLevel 4 Laryngoscope, 133:3208–3215, 2023

Published: March 2023

AbstractRecently, higher‐order topological insulators (HOTIs), accompanied by topologically nontrivial boundary states with a codimension larger than one, have been extensively explored because of unconventional bulk‐boundary correspondences. As a novel type of HOTIs, very recent works have explored the square‐root HOTIs, where the topologically nontrivial nature of bulk bands stems from the square of the Hamiltonian. In this paper, 2D square‐root HOTIs are experimentally demonstrated in photonic waveguide arrays written in glass using femtosecond laser direct‐write techniques. Edge and corner states are clearly observed at visible light spectra. The dynamical evolutions of topological boundary states are experimentally demonstrated, which verify the existence of photonic corner states in two band gaps. The symmetry‐protected corner states in the photonic square‐root HOTI may have potential applications in information processing and lasing.

Published: March 2023

AbstractIn recent years, with the rapid development of military, optical communication, biological imaging, and other fields, practical engineering applications such as fiber‐optic gyroscope, wavelength division multiplexing, and optical coherence tomography have put forward higher requirements on light sources. Amplified spontaneous emission (ASE) light source has become an excellent candidate due to its advantages such as suitable bandwidth, low coherence, and high power. Although the ASE light source is developed to a certain extent, there is still great room for improvement in the choice of gain medium and device structure. In order to accelerate the development and practical engineering application of ASE optoelectronic devices, it is of great significance to grasp the basic characteristics of the gain materials and the design of the device structure. In this review, the principle of the ASE effect and its difference with the generation of lasing are analyzed. Then, the optical gain properties of various gain materials, together with different structural types of electrically pumped ASE devices and their practical engineering applications, are summarized. Finally, the new ASE light‐emitting devices integrated with high‐gain materials and low‐cost structures are prospected to provide more ideas for their development.

AbstractControlling the crystallization of advanced, high‐performance polymeric materials during 3D printing is critical to ensure that the resulting structures have appropriate mechanical properties. In this work, two grades of polyetherketoneketone (PEKK 6002 and PEKK 7002) are used to print 3D specimens via a fused filament fabrication process. The samples are compared with polyetheretherketone printed under the same conditions. Two approaches for controlling the crystallization process are undertaken. The first involves adjustment of the chamber temperature between room temperature and 190 °C to create two regions where crystallization is governed by the slow diffusion process and elevated by limiting the nucleation process. The second approach involves selection of PEKK materials with varying crystallization kinetics, namely. Application of this method into 3D‐printing process allows for printing semicrystalline materials with tailored mechanical, thermal, and chemical properties as either amorphous or in situ crystallized products. The studies undertaken here provide the basis to eliminate expensive and time‐consuming post‐processing of 3D fabricated parts. In particular, solutions for the avoidance of poor adhesion to the building plate and weak interlayer adhesion that can lead to warping are described. The materials are divided into three groups, slow, moderate, and too fast crystallization kinetics.
An examination of frontline employee–customer incidental similarities in service failure and recovery contexts

Published: March 2023

AbstractDeveloping rapport during the “moment of truth” when frontline employees (FLEs) interact with customers has long been an important topic for researchers and managers. We suggest incidental similarities—seemingly trivial shared points of comparison between customers and FLEs—can play a vital role during this juncture in service failure and recovery contexts. Across two experimental studies, we investigate several relationships impacted by the presence or absence of an incidental similarity between FLEs and customers for their effect on satisfaction and repatronage intentions. Results suggest incidental similarities can reduce failure attributions toward service providers and improve these important customer‐related outcomes (study 1). Results of study 2 extend our findings, demonstrating that rapport can serve as a mediating mechanism explaining the relationship between incidental similarities and these key service outcomes. Study 2 also reveals that FLE authenticity acts as a boundary condition of this relationship, accentuating the indirect, conditional relationships between incidental similarities, and satisfaction and repatronage intentions. Critically, we demonstrate that an incidental similarity can be even more effective when there is no recovery. By pointing out the role of incidental similarities in service encounters, our research makes significant contributions to aiding understanding of how rapport can be developed during the relatively brief time customers interact with service employees.

AbstractWe developed a miniaturized coplanar Vivaldi antenna (M‐CPVA) for microwave imaging applications. First, a conventional coplanar Vivaldi antenna (CPVA) was designed. Then, the M‐CPVA was developed by properly cropping the exponential flares. The impedance bandwidth and near‐field electric field distribution of the M‐CPVA were improved as compared to the conventional CPVA. In particular, the designed M‐CPVA was 58.6 × 92 × 1.6 mm3in size and operated from 1 to 7.5 GHz, corresponding to a fractional bandwidth of 152%. Last, the produced M‐CPVA was tested in a microwave imaging system for continuous monitoring of brain strokes. The stability and accuracy of the imaging results imply that the proposed antenna could be useful for microwave brain stroke monitoring applications.

Published: March 2023

AbstractIn this letter, the extensive measurements and simulations are conducted at 28 GHz in the large waiting hall environments. The rotated linear array‐based method of measurement is proposed. The rotated linear array‐based method of measurement and the uniform virtual array‐based method of measurement are performed and compared. The space‐alternating generalized expectation‐maximization algorithm is exploited to extract the propagation parameters of multipath components (MPCs). Path loss models are illustrated based on self‐developed ray tracing simulator. A good agreement is achieved between the simulated results and the measured results, so the correctness of improved ray tracing method is verified. The results show that the measured results of the rotated linear array‐based method and the uniform virtual array‐based method are consistent. But the rotated linear array‐based method is simpler and less time‐consuming. A universal path loss model is proposed in the large waiting hall scenarios at 28 GHz. Moreover, clustering of MPCs is investigated by the K‐power‐mean algorithm. The number of clusters are calculated and analyzed.
Benchmarking quality of care using patient reported outcome measure data for patients presenting with musculoskeletal conditions in primary care GP practices

Published: March 2023

AbstractBackgroundPatient Reported Outcome Measures (PROMs) evaluate health status from a patient perspective. They can be used to support care at a patient level but also collectively to review quality of care across care providers. Vast amounts of patients with musculoskeletal (MSK) conditions present to General Practice (GP) primary care practitioners each year. Variation in patient outcomes in this setting however has not been reported.ObjectiveTo identify variation in patient outcomes measured using the musculoskeletal health questionnaire (MSK‐HQ) PROM for adults presenting to 20 GP practices in the UK with MSK conditions.MethodsA secondary analysis of the STarT MSK cluster randomised controlled trial dataset. A standardised case‐mix adjustment model, adjusting for condition complexity co‐variates, was used to calculate predicted 6‐month follow‐up MSK‐HQ scores, and used to compare adjusted and un‐adjusted health gain (n = 868). Patient MSK‐HQ change outcomes were aggregated to practice level and boxplots used to display outlier GP practices for un‐adjusted and adjusted outcomes.ResultsSubstantial variation in patient outcomes was seen across the 20 practices, even after case‐mix adjustment, with mean change in MSK‐HQ scores ranging from 6 to 12 points. Boxplots displaying un‐adjusted outcomes showed one negative GP practice outlier and two positive outliers. However, the boxplots displaying case‐mix adjusted outcomes showed no negative outliers, with two practices remaining as positive outliers, and one practice additionally becoming a positive outlier.ConclusionThis study showed a two‐fold GP practice variation in patient outcomes measured using the MSK‐HQ PROM. To our knowledge it is the first study to demonstrate that (a) a standardised case‐mix adjustment method can be used to fairly compare patient health outcome variation in GP care, and (b) that case‐mix adjustment changes benchmarking findings with regards to provider performance and outlier identification. This has important implications for identifying best practice exemplars and thereby helping to improve the quality of MSK primary care in the future.
