Authors: El-Far Doaa Hassan , Mandour Mahmoud Fawzy , El-Aziz Mahmoud Abd , El-Sheikh Mohamed Nasser 
Published: January 2023

Background: Hyaluronic acid (HA) enriched fat graft myringoplasty (FGM) has many advantages compared with conventional MP using temporalis fascia and cartilage perichondrium, as it is short, easy, economical, and with minimum invasion and initiate a more rapid and complete healing process. This study aimed to evaluate the effectiveness of fat plug MP, enriched with HA for closure of medium size tympanic membrane perforations (TMP) (25-50% of TM surface area) and to compare it with classical cartilage perichondrium MP.
Methods: This prospective randomized control study was conducted on 50 cases with TMP. Cases were allocated into 2 groups: group I: tympanoplasty was done using fat graft enriched with HA. In group I hyaluronic was applied as gel foam soaked with commercially available HA and group II: tympanoplasty was done using cartilage perichondrium. All cases were subjected to ENT examination and pre-operative audiological evaluation including pure tone audiometry (PTA) and tympanometry.
Results: Graft taking was statistically insignificant after 3 months compared to 1 month follow ups in both groups. Air bone gap (ABG) was insignificantly different in the pre and postoperative ABG in both groups. Hearing was significantly improved postoperatively compared to preoperatively in both groups (P value<0.001). There was no significant difference in distribution of side of perforation in both groups. Hearing gain was statistically insignificant between both groups (P value=0.256). Hearing was significantly improved postoperatively compared to preoperatively in both groups (P value <0.001).
Conclusion: In cases with TMP, the TM HA enriched Fat graft myringoplasty (FGM) is an effective procedure with minimal invasion in management of the medium sized TMP. Also, it is safe and feasible procedure. Hearing was significantly improved postoperatively compared to preoperatively in both groups: HA enriched FGM group and MP with cartilage perichondrium group respectively.

Published: January 2023

ImportanceApproximately 60% of women physicians in emergency medicine (EM) experience gender-based discrimination (GBD). Women physicians are also more likely to experience GBD than men physicians, particularly from patients, other physicians, or nursing staff.ObjectiveTo describe the responses of men who are academic department chairs in EM to GBD directed toward a woman colleague.Design, Setting, and ParticipantsThis qualitative study was a secondary data analysis drawn from interviews of men EM academic department chairs at 18 sites who participated in a qualitative descriptive study between April 2020 and February 2021 on their perceptions of the influence of gender and leadership in academic medicine. Narrative data related to GBD were extracted and coded using conventional content analysis. Codes were clustered into themes and subthemes and summarized. Data were analyzed from November to December 2021.ExposureSemistructured interviews conducted via teleconferencing.Main Outcomes and MeasuresQualitative findings identifying experiences witnessing or learning about incidents of GBD against women colleagues, the impact of these observations, and personal or leadership actions taken in response to their observations.ResultsAll 18 men participants (mean [SD] age, 52.2 [7.5] years; mean [SD] time as a department chair, 7.2 [5.1] years) discussed witnessing or learning about incidents of GBD against women colleagues. The participant narratives revealed 3 themes: emotional responses to GBD, actions they took to address GBD, and reasons for not taking action to address GBD. When witnessing GBD, participants felt anger, disbelief, guilt, and shame. To take action, they served as upstanders, confronted and reported discrimination, provided faculty development on GBD, or enforced “zero-tolerance” policies. At times they did not take action because they did not believe the GBD warranted a response, perceived a power differential or an unsupportive institutional culture, or sought self-preservation.Conclusions and RelevanceIn this qualitative study of men physician leaders, we found all participants reported feeling troubled by GBD against women colleagues and, if possible, took action to address the discrimination. At times they did not take action because of unsupportive workplace cultures. These findings suggest that institutional culture change that supports the interventions of upstanders and does not tolerate GBD is needed.

AbstractThe FeS2 has abundant reserves and a high specific capacity (894 mAh g−1), commonly used to fabricate Li‐FeS2 primary batteries, like LiMx‐FeS2 thermal batteries (working at ≈500 °C). However, Li–FeS2 batteries struggle to function as rechargeable batteries due to serious issues such as pulverization and polysulfide shuttling. Herein, highly reversible solid‐state Li‐FeS2 batteries operating at 300 °C are designed. Molten salt‐based FeS2 slurry cathodes address the notorious electrode pulverization problem by encapsulating pulverized particles in time with e− and Li⁺ flow conductors. In addition, the solid electrolyte LLZTO tube serves as a hard separator and fast Li+ channel, effectively separating the molten electrodes to construct a liquid–solid–liquid structure instead of the solid–liquid–solid structure of LiMx‐FeS2 thermal batteries. Most importantly, these high‐temperature Li–FeS2 solid‐state batteries achieve FeS2 conversion to Li2S and Fe at discharge and further back to FeS2 at charge, unlike room‐temperature Li‐FeS2 batteries where FeS and S act as oxidation products. Therefore, these new‐type Li‐FeS2 batteries have a lower operating temperature than Li‐FeS2 thermal batteries and perform highly reversible electrochemical reactions, which can be cycled stably up to 2000 times with a high specific capacity of ≈750 mAh g−1 in the prototype batteries.

AbstractThe economic viability of carbon dioxide electroreduction (CO2R) relies on improved performance accompanied by scalable system design. Membranes are commonly used for the separation of reduction and oxidation products as well as to provide a suitable micro‐environment for CO2R. Commercial membranes often address only one of the key challenges in CO2R: either they offer a suitable micro‐environment for CO2R (e.g., anion exchange membrane) or suppress carbonate cross‐over (e.g., cation exchange membrane and bipolar membrane). This work presents a cation‐infused ultrathin (≈3 µm) solid polymer electrolyte (CISPE) that concomitantly addresses both challenges via a bidirectional ion transport mechanism and suppressed cathode flooding. This directly‐deposited CISPE (that substitutes the commonly used pre‐made membrane) enables record high full‐cell energy efficiency of 28% at 100 mA cm−2 for one‐step CO2 electrolysis to ethylene (C2H4) with ≈110 h of stable operation. This translates into a record low energy cost of 290 GJ per ton C2H4 for the end‐to‐end process (i.e., CO2 capture and electroreduction, carbonate regeneration, CO2 separation from anode and cathode streams) in a membrane electrode assembly CO2R. The present work offers a versatile design paradigm for functional polymer electrolytes, opening the door to stable, and efficient electrolysis of high‐value feedstock chemicals and fuels using low‐cost catalysts.

AbstractA visible‐light‐triggered synthesis of sulfonamide was developed via an electron donor‐acceptor (EDA) complex in the more environmentally friendly green solvent 2‐methyltetrahydrofuran (MeTHF). This method offers a novel strategy for synthesizing sulfonamide in high yields at room temperature, without the need of a base, any additional photocatalyst, or transition metals. Simple operation, mild reaction conditions, excellent atom economy, and excellent functional group compatibility are the main advantages of this reaction.

Published: January 2023

AbstractA critical query on literature is the approach used to immobilize homogeneous catalysts to improve their efficiency and recyclability. This work aims to compare the immobilization level of a kind of Pd‐N,N′‐bis(salicylidene)‐o‐phenylenediamine complex on high surfaces of polymeric resins to provide heterogenous catalysts for Mizorocki‐Heck reaction. The preparation method involves two strategies: (i) polymerization of the ligand before the complex‐synthesis in a “multi‐step (MS)” approach and (ii) a direct “one‐step” (OS) immobilization by polymerization of the metal‐containing monomers (MCMs) as co‐monomer. Both approaches effectively yield polymers with a larger surface area, over 700 m2 g−1, and suitable thermic properties to use in the proposed reaction. In addition, the characterization of the polymers by XRD, XPS, and TEM demonstrates notable differences in Pd species on polymer support associated with the methodological approach to immobilizing the metal complex.

Published: January 2023

AbstractWith the increasing use of plastic product, there is a large amount of plastic waste containing plasticizer, especially dibutyl phthalate (DBP), which would pollute the water and soil, and even cause diseases to humans and wildlife. Normally, the DBP in soil or water is trace, making it hard to be detected exactly. To solve this case, core‐shell structured molecularly imprinting polymers (P‐MIPs) were synthesized. Combing with photoresponsive monomer 4‐[(4‐methacryloyloxy) phenylazo] benzenesulfonic acid (MAPASA), the prepared P‐MIPs can be controlled by light to specifically absorb (440 nm or darkness condition) and release (365 nm) DBP, with the absorption capacity of 4.45 mg g−1 and imprinting factor of 3.56. More important, the P‐MIPs exhibit excellent reusability and practicability by applied to enrich and extract DBP in river water samples. In conclusion, the proposed P‐MIPs offer an idea for the detection of trace pollutants.

Published: January 2023

AbstractSulfurized poly(acrylonitrile) (SPAN) is a prominent example of a highly cycle stable and rate capable sulfur/polymer composite, which is solely based on covalently bound sulfur. However, so far no in‐depth study on the influence of nitrogen in the carbonaceous backbone, to which sulfur in the form of thioketones and poly(sulfides) is attached, exists. Herein, we investigated the role of nitrogen by comparing sulfur/polymer composites derived from nitrogen‐containing poly(acrylonitrile) (PAN) and nitrogen‐free poly(vinylacetylene) (PVac). Results strongly indicate the importance of a nitrogen‐rich, aromatic carbon backbone to ensure full addressability of the polymer‐bound sulfur and its reversible binding to the aromatic backbone, even at high current rates. This study also presents key structures, which are crucial for highly cycle and rate stable S‐composites.

Published: January 2023

AbstractHydrazine (N2H4) is a highly toxic and harmful chemical reagent. Fluorescent probes are simple and efficient tools for sensitive monitoring of N2H4 enrichment in the environment, humans, animals, and plants. In this work, a ratiometric fluorescent probe (FP‐1) containing coumarin was used for hydrazine detection. The proposed FP‐1 probe had a linear detection range of 0–250 μM and a limit of detection (LOD) of 0.059 μM (1.89 ppb). A large red Stokes shift was observed in fluorescence and UV–vis absorption spectra due to the hydrolysis of ester bonds between FP‐1 and hydrazine. The hydrazine detection mechanism of FP‐1 was also investigated using density functional theory (DFT) calculations. Finally, FP‐1 could sensitively and selectively monitor hydrazine in actual water samples and BEAS‐2B cells. Therefore, it has great application potential in environmental monitoring and disease diagnosis.

Published: January 2023

AbstractAn economical and green approach to the synthesis of naphthyl derivative for detection of l‐carnitine (3‐hydroxy‐4‐N‐trimethyl‐aminobutyrate) is practically important. We developed a naphthyl derivative as a probe showing ‘turn‐on’ response towards l‐carnitine selectively at pH 7.2 through ICT mechanism with a good limit of detection (LOD) of 0.126 μM. Using Job's plot for determining the binding stoichiometry, it was found that probe could form a more stable complex (1:1) with carnitine. The binding constant (K) between probe and carnitine was calculated as 8 × 107 M−1 using the Benesi–Hildebrand plot. The binding interaction of the probe with l‐carnitine was confirmed by nuclear magnetic resonance titrations, Fourier‐transform infrared spectroscopy, photo physical studies and density functional theory calculations. Meanwhile, the probe can be used to quantitatively detect carnitine in food samples.
The link between psychological distress and survival in solid tumor patients: A systematic review
Authors: Roche Kayla N. , Cooper Diane , Armstrong Terri S. , King Amanda L. 
Published: January 2023

AbstractPurposeResearch has demonstrated that solid tumor patients experience high levels of psychological distress at the time of diagnosis. While distress has been associated with many adverse clinical outcomes, little is known about how this symptom may influence the disease trajectory for cancer patients, affecting outcomes such as progression, recurrence, and survival. The purpose of this systematic review was to explore the literature linking distress with survival in solid tumor patients, which may guide future work exploring clinical outcomes as a function of distress.MethodsA systematic search of PubMed, Embase, and Web of Science was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta‐Analyses) guidelines with predefined eligibility criteria. Thirteen studies met the inclusion criteria and were selected for review.ResultsFindings from this review demonstrated a weak‐to‐moderate relationship between cancer patients' experience of distress and overall survival, with most included studies (11/13) finding at least one predictive analysis to be significant when controlling for confounders. However, significant heterogeneity in the literature, particularly with study sample characteristics and varying methodologies, made direct comparisons across studies challenging.ConclusionFindings from this review suggest that psychological distress may have an impact on disease‐related outcomes, including (but not limited to) survival. Future work should consider performing disease‐specific analyses controlling for key prognostic factors to better understand the nuanced relationship between distress and clinical outcomes, which may allow further understanding of the biological underpinnings of this relationship and enable the development of targeted interventions for improving distress.
A long‐term archival analysis of social influence on online wine evaluations: Effects of consensus and expertise
Authors: Gokcekus Omer , Gokcekus Samin , Hewstone Miles 
Published: January 2023

AbstractWhen forming opinions, people often rely on the behaviours and beliefs of others; this phenomenon has been understood by social psychologists as ‘social influence’. Online evaluations of goods provide a naturalistic context in which to investigate social influence. We collected information from 20,397 notes about 209 wines posted on a wine social networking site over the course of 10 years to examine the social influence on wine evaluations. Our analyses provide evidence for both normative and informational social influence on online wine evaluations. However, normative influence outweighs the effect of judgements made by experts. The influence of prior evaluations is strongest for the first few individuals who post their notes, and social influence increases as a function of source uniformity. Furthermore, expert members' evaluations are not more influential than other individuals' evaluations. Our results provide evidence for significant effects of social influence in an applied setting, impacting wine consumers that are exposed to the opinions of others, and have implications for how goods are advertised online.

Published: January 2023

Comprehensive SummaryA novel polyurethane polymer containing perylene diimide (PDI) unit and aniline segment, denoted as PU‐PDI, was designed and synthesized. Their tensile property and photophysical characteristic were investigated using various experimental and theoretical techniques. It is found that the elongation of PU‐PDIs can reach more than 1000%, indicating good tensile performance. Moreover, based on the photoinduced electron transfer mechanism, the aniline segments in polyurethane can quench the auto‐fluorescence of PDI unit to a negligible value, which overcomes the intractable fluorescence drawbacks of conventional colour filters. The non‐emissive characteristic, in combination with the good thermal stability and tensile property of PU‐PDI, provides a feasible design strategy to fabricate optical filters with high display quality.

Published: January 2023

AbstractThe tetranuclear Cu2+/Ca2+/Ca2+/Cu2+ complex based on Malten ligand has been investigated as a platform for anion binding. Simple organic carboxylates and non‐steroidal anti‐inflammatory drugs (NSAIDs) have been tested, revealing the ability of the platform to bind them. The receiving platform hosts at least two guests in solution although a third anion can be bound, as suggested by X‐ray diffraction analysis. The addition of the anions is accompanied by a color change of the solution, making the system a colorimetric sensor for carboxylates (LOD values comprised between 3.6 and 20.7 ppm). A fluorescent system consisting of the 2‐(3‐oxido‐6‐oxoxanthen‐9‐yl)benzoate (fluorescein anion) linked to the tetranuclear platform has been also prepared and used in a chemosensing ensemble approach to signal the presence of the selected anions (Log K between 2.6 and 5.6 for the addition of two guests). The latter also works in a paper strip test, offering the chemosensor a possible practical application.
How objectifiers are granted power in the workplace

Published: January 2023

AbstractObjectification often has profound negative consequences for its victims, yet we argue that objectification may have positive ancillary implications for the perpetrators. Drawing from system justification theory, we posit that, especially in organizations characterized by higher power distance, objectifying supervisors would be afforded more power by their subordinates because they would deem such behaviour as more typical (i.e., descriptive justification) and more desirable (i.e., prescriptive justification). The results of two experiments (N = 443 and N = 211) showed that high (vs. low) power distance subordinates afforded less power to a non‐objectifying supervisor (but not more power to an objectifying supervisor), and that prescriptive justification (but not descriptive justification) mediated the interaction effect of objectification and power distance on power affordance. In a field survey with dyads of supervisors and subordinates (N = 122), we found that subordinates with relatively high power distance orientations afforded power to their objectifying supervisors through prescriptive justification. Our research contributes to objectification literature by demonstrating when and how supervisor objectification can be rationalized and perpetuated through granting objectifiers power.

AbstractBackgroundTo investigate the effect of nutritional status on radiation‐induced acute toxicities in nasopharyngeal carcinoma (NPC) patients before radiotherapy.MethodsNutritional status of 228 patients with NPC who received intensity‐modulated radiotherapy was retrospectively analyzed by modified nutrition index (m‐NI). Cumulative grading score of six common acute toxicities were defined as total score for acute toxicities.ResultsM‐NI ≤6 is a risk factor for xerostomia (p = 0.016, OR = 0.208, 95% CI 0.058–0.743), oral mucositis (p = 0.016, OR = 0.287, 95% CI 0.104–0.793), dysgeusia (p = 0.001, OR = 0.028, 95% CI 0.004–0.217), and dysphagia (p = 0.015, OR = 0.251, 95% CI 0.083–0.764) as well in patients with NPC. Total score of radiation‐induced acute toxicities of patients with malnutrition (13.6 ± 1.7) was significantly higher than that of patients with normal nutrition (12.0 ± 2.4) (t = −5.464, p < 0.001).ConclusionsNPC patients with malnutrition before radiotherapy develop more serious dysgeusia, oral mucositis, dysphagia, and xerostomia after intensity‐modulated radiotherapy.
