Published: July 2023

AbstractFull utilization of the excited species at both singlet states (1R*) and triplet states (3R*) is crucial to improving electrochemiluminescence (ECL) efficiency but is challenging for organic luminescent materials. Here, an aggregation‐induced delayed ECL (AIDECL) active organic dot (OD) containing a benzophenone acceptor and dimethylacridine donor is reported, which shows high ECL efficiency via reverse intersystem crossing (RISC) of non‐emissive 3R* to emissive 1R*, overcoming the spin‐forbidden radiative decay from 3R*. By introducing dual donor‐acceptor pairs into luminophores, it is found that nonradiative pathway could be further suppressed via enhanced intermolecular weak interactions, and multiple spin‐up conversion channels could be activated. As a consequence, the obtained OD enjoys a 6.8‐fold higher ECL efficiency relative to the control AIDECL‐active OD. Single‐crystal studies and theoretical calculations reveal that the enhanced AIDECL behaviors come from the acceleration of both radiative transition and RISC. This work represents a major step towards purely organic, high‐efficiency ECL dyes and a direction for the design of next‐generation ECL dyes at the molecular level.
Technical note: A freeware, equitable approach to dental topographic analysis
Authors: Morley Matthew J. , Berthaume Michael A. 
Published: July 2023

AbstractDental topographic analysis has proved a valuable tool for quantifying dental morphology. Established workflows often use proprietary software for pre‐processing dental surfaces, rendering the method expensive and inaccessible to many. This study explores the use of freeware pre‐processing alternatives. We tested 4 decimation tools and 13 smoothing tools across 7 different freeware packages. Surfaces generated via proprietary software could not be replicated, but it was possible to obtain statistically similar measurements using freeware. Based on this investigation, we propose a freeware workflow for researchers to conduct dental topographic analysis, with the expectation that their results will be comparable to that obtained through proprietary methods.
Trabecular bone structure of the proximal capitate in extant hominids and fossil hominins with implications for midcarpal joint loading and the dart‐thrower's motion

Published: July 2023

AbstractObjectivesThis research examines whether the distribution of trabecular bone in the proximal capitates of extant hominids, as well as several fossil hominin taxa, is associated with the oblique path of the midcarpal joint known as the dart‐thrower's motion (DTM).Materials and MethodsWe analyzed proximal capitates from extant (Pongo n = 12; Gorilla n = 11; Pan n = 10; fossil and recent Homo sapiens n = 29) and extinct (Australopithecus sediba n = 2; Homo naledi n = 1; Homo floresiensis n = 2; Neandertals n = 3) hominids using a new canonical holistic morphometric analysis, which quantifies and visualizes the distribution of trabecular bone using relative bone volume as a fraction of total volume (rBV/TV).ResultsHomo sapiens and Neandertals had a continuous band of high rBV/TV that extended across the scaphoid, lunate, and hamate subarticular regions, but other fossil hominins and extant great apes did not. A. sediba expressed a distinct combination of human‐like and Pan‐like rBV/TV distribution. Both H. floresiensis and H. naledi had high rBV/TV on the ulnar‐side of the capitate but low rBV/TV on the radial‐side.ConclusionThe proximal capitates of H. sapiens and Neandertals share a distinctive distribution of trabecular bone that suggests that these two species of Homo regularly load(ed) their midcarpal joints along the full extent of the oblique path of the DTM. The observed pattern in A. sediba suggests that human‐like stress at the capito‐scaphoid articular surface was combined with Pan‐like wrist postures, whereas the patterns in H. floresiensis and H. naledi suggest their midcarpal joints were loaded differently from that of H. sapiens and Neandertals.

AbstractINTRODUCTIONFew studies have explored dementia risk according to sex and gender including for transgender and non‐binary adults. This study evaluated dementia risk factors and risk scores among cisgender, transgender, and non‐binary adults.METHODSObservational data were drawn from the 2019 Behavioral Risk Factor Surveillance System. A matched‐cohort approach was used to develop sex (male, female) and gender identity cohorts (cisgender men, cisgender women, transgender men, transgender women, and non‐binary adults) for comparison. Dementia risk scores were calculated using established mid‐life and late‐life risk score algorithms.RESULTSMales had higher overall mid‐life dementia risk, and lower late‐life Alzheimer's disease risk compared to females. Transgender men, transgender women, and non‐binary adults had higher overall late‐life risk compared to both cisgender men and women.DISCUSSIONFuture research is needed to build the evidence base for specific risk factors that may be contributing to higher overall risk among understudied and underserved gender groups.Highlights
Using data from the 2019 Behavioral Risk Factor Surveillance System, this matched‐cohort study found that those assigned female at birth had lower overall mid‐life dementia risk and higher overall late‐life Alzheimer's disease (AD) risk compared to those assigned male at birth.
Transgender men, transgender women, and non‐binary adults all showed higher overall late‐life AD risk compared to cisgender men and cisgender women.
Between‐group differences were found in the incidence of specific risk and protective factors for dementia and AD.
Sterile Processing Department Benchmarking for Labor Productivity
Authors: Kusler‐Jensen Jane 
Published: July 2023

ABSTRACTPersonnel are a critical resource in health care. Ensuring that enough staff members are available to provide necessary care for patients is of utmost importance. Leaders can use labor productivity measures to compare their department to other like departments and set a benchmark to ensure that staff members are performing at their fullest potential. Productivity measures provide data to help leaders better understand how well processes, personnel, and technology are performing the required work of the department. Benchmarking the sterile processing department for labor productivity is one of the measures that leaders can use to ensure that staff members understand expectations and the role that they play in providing quality care and improving patient outcomes. Benchmarking provides the sterile processing leader with the ability to measure performance; look for opportunities to improve performance; and ensure that staff members are working safely and efficiently, especially during staffing shortages.

Published: July 2023

ABSTRACTThe use of performance qualification (PQ) tests for ultrasonic cleaners leads to improvements in the quality of processing lumened surgical instruments. Evidence and national standards assert the need for health care facilities to implement a quality management system related to device reprocessing and testing the adequacy of mechanical cleaning processes. Testing includes showing that ultrasonic cleaners have properly functioning cavitation, soil removal, and lumen perfusion capabilities. This article summarizes survey responses from an audit of sterile processing personnel regarding ultrasonic cleaning units in health care facilities. The article also provides guidance to facilities regarding assessing installation, operational, and PQ related to ultrasonic cleaning equipment. Implementing PQ testing of ultrasonic cleaners in sterile processing units leads to a decreased risk of soiled instrumentation in the OR, which can reduce the risk of patient infection and adverse events.

Published: July 2023

AbstractIn this study, green synthesis of titanium nanoparticles using liquids metabolites of microalgae, Porphyridium cruentum, was performed to evaluate potential biotechnological activity. The rising rates of multidrug‐resistant bacteria and the number of cancer patients are driving the search for novel antimicrobial and anticancer agents to combat this threat. In recent years, with the increasing number of studies, nanomaterials are starting to be better understood and are emerging as a solution to this problem. Especially, green synthesized nanoparticles with anticancer, antioxidant, and antimicrobial activities have potential in biomedical applications because of their eco‐friendly and biocompatible nature. Scanning electron microscopy (SEM) images revealed that spherical shaped Ti‐NPs' size ranged from 62 to 133 nm. This study aimed to assess the effectiveness of antibacterial activity of Ti‐NPs and chitosan‐coated Ti‐NPs against Escherichia coli and Staphylococcus aureus using disc diffusion assay. It demonstrated the concentration‐dependent cytotoxic effect of Ti‐NPs of human prostate adenocarcinoma (PC‐3), human alveolar adenocarcinoma (A549), and human mammary gland adenocarcinoma (MDA‐MB) cancer cell lines. This present study shows promising outcomes for possible future applications of synthesized Ti‐NPs as a novel antibacterial and cytotoxic agent for biomedical applications such as drug delivery, biosensor, and hyperthermia.
Abundance of radioactive technetium in Przybylski's star revisited

Published: July 2023

AbstractWe have searched for lines of the radioactive element technetium (Tc) in the spectrum of Przybylski's star (HD 101065). The nuclei of this chemical element are formed in the slow process of capturing thermalized neutrons. The possible lines of Tc I are heavily blended. We have synthesized the profile of one resonance line at 4297.06 Å , which is also a part of the complex blend, and we arrived at a decision that it is not visible in the spectrum (as was first noted by Ryabchikova), casting doubt on the existence of technetium in the atmosphere of the Przybylski's star. Therefore, based on our calculated combined profile, which has been adjusted to the observed blend profile at 4297.2 Å (that may possibly contain the resonance technetium line 4297.06 Å), we reduce the maximum technetium abundance to (Tc/H) = 2.5. This value can be considered only as an upper limit of the technetium abundance in the Przybylski's star.
Can theSustainable Development Goalssupport nexus thinking in companies? The case of water
Authors: Morris Jonathan , Guenther Edeltraud 
Published: July 2023

AbstractMany initiatives and targets have been developed to address the unsustainable consumption of resources that consider the interconnected impacts and trade‐offs that exist between different resources that are critical for the functioning of human societies and economies. Despite efforts to engage with the business sector to achieve these aims, there lacks sufficient integration of globally agreed targets (such as the United Nations Sustainable Development Goals) into business operations, and even less is understood on how these goals translate into management processes. Using a case study of water, and a consideration of the Water‐Energy‐Food‐Ecosystem (WEFE) nexus, this paper looks at the public communications made by FTSE 100 companies via their annual and CSR reports, identifying that where present, water management disclosures remain in silo and are not explicitly linked to global sustainable development goals.
Employee‐sharing and consumers' brand attitudes during COVID‐19: A CSR perspective
Authors: (Monroe)Meng Lu , Huang Xin , Xie Yufeng , Jia Weiwei 
Published: July 2023

AbstractThe rapid proliferation of COVID‐19 has dealt a heavy blow to many companies. Under these circumstances, employee‐sharing has become a valuable strategy to help enterprises resume work and production. Based on the event system theory, we explored the impact of employee‐sharing event strength on consumers' brand attitudes during the COVID‐19 pandemic through a corporate social responsibility (CSR) lens. Also, we verified that employee‐sharing event strength during the COVID‐19 pandemic positively affected consumers' internal (ICSR) and external (ECSR) perceptions of enterprises, improving consumers' brand attitudes and validating the positive moderating effect of customer‐company identification. Thus, this study provides theoretical insights and managerial implications for CSR.
Interaction and Energy Decomposition Analyses to Predict Stability of Tetraaryl Square Planar Cobalt Complexes

Published: July 2023

AbstractThe sodium‐mediated cobaltation of pentafluorobenzene using the bimetallic base [NaCo(HMDS)3] (HMDS=N(SiMe3)2) has been reported to afford a novel tetraaryl Co(II) square planar complex. Yet, the preparation of analogue structures with 1,2,3,4‐tetrafluorobenzene, 1,3,5‐trichlorobenzene, and 1,4‐dibromo‐2,5‐difluorobenzene remains elusive. While the metalation step proceeds leading to stable [NaCo(HMDS)2Ar] species, the ligand redistribution process to afford the tetraaryl Co(II) square planar complexes does not take place. Herein we report a density functional theory study in combination with electronic structure and energy decomposition analyses to shed light on the electronic and steric requirements to afford such complexes. Our findings show that the formation of the Co(II) square planar complexes depends on the right balance between intramolecular X⋅⋅⋅X and Na⋅⋅⋅X (X=H, F, Cl, Br) interactions. The latter further induces a ‘seesaw effect’, whereby the aryl ligand acts as a ‘seesaw’ allowing two X atoms in ortho positions to interdependently interact with Na. Only by considering both attractive and repulsive Na(X)⋅⋅⋅X interactions, the correct stability of the square planar complexes observed in experiments can be predicted computationally. We envision these insights to guide the rational design of novel square planar metal complexes for C−C coupling, a field that is still dominated by scarce and expensive precious metals.
Comparison of calculation models for flexural capacity of RC beams strengthened with TRC in China and Germany
Authors: Xu Ronghua , Curbach Manfred 
Published: July 2023

AbstractThe new innovative composite material textile reinforced concrete (TRC) has been intensively investigated in Germany since the end 1990s. It has become increasingly important in the construction industry. Compared with conventional steel reinforcement, TRC has advantages such as higher load‐bearing capacity, higher strength‐to‐weight ratio, better ductility, and non‐corrosive behavior. This made them a subject of extensive research and diverse applications both nationally and internationally. In 2004, Xu et al. started research on bond properties of TRC in China in cooperation with Hans‐Wolf Reinhardt et al. from the University of Stuttgart in Germany. Since then, there have been numerous researches on TRC in China. This article introduces a calculation method for the flexural capacity of reinforced concrete (RC) beams strengthened with TRC in China. For comparison, the dimensioning procedure in Germany is also presented. Subsequently, the two models are compared with each other in a case study. Both models in China and Germany have the same mathematical background and also provide similar results. However, they have some differences in definitions of material characteristics (e.g., design concrete compressive strength, strain, and stress distribution) and consideration of the damage resulting from the preloading stage.
Synthesis and Reactivity of Hetero‐Pnictogen Diazonium Analogs Stabilized by Transition Metal Units

Published: July 2023

AbstractThe reactivity of the mixed dipnictogen complexes [{CpMo(CO)2}2(μ,η2 : 2‐PE)] (E=P, As, Sb) towards different group 14 electrophiles is reported. The resulting library of cationic compounds [{CpMo(CO)2}2(μ,η2 : 2‐EPR)]+ (R=Mes (2,4,6‐C6H2Me3), CH3, CPh3, SnMe3) represents formally inorganic diazonium homologs which are stabilized by transition metal units. Modifying the steric and electronic properties of the electrophile drastically impacts the respective P−R bond lengths and is accompanied by increasing (SnMe3>CPh3>CH3) dynamic behavior in solution. In contrast to the well‐studied organic analogs, the prepared compounds are stable at room temperature. The subsequent reaction of the model substrate [{CpMo(CO)2}2(μ,η2 : 2‐P2Me)][OTf] ([OTf]−=[CF3SO3]−) with different N‐heterocyclic carbenes (NHCs) leads to an addition at the unsubstituted P atom which is also predicted by computational methods. NMR spectroscopy confirms the formation of two isomers sync/gauche‐[{CpMo(CO)2}(μ,η2 : 1‐P(NHC)PMe){CpMo(CO)2}][OTf]. X‐ray crystallographic characterization and additional DFT calculations shed light on the spatial arrangement as well as on the possible formation pathways of the isomers.

Published: July 2023

AbstractGold (III) cyclometalated based amphiphiles in aqueous media have been revealed with excellent supramolecular transformations to external stimuli to open new pathways for soft functional material fabrications. Herein, we report a new chiral cyclometalated gold (III) amphiphile (GA) assembling into lamellar nanostructures in aqueous media confirmed with transmission electron microscopy (TEM). Counterion exchange with D‐, L‐, or racemic‐camphorsulfonates features the significant supramolecular helicity enhancements, enabling transformations of GA from lamellar structure to vesicles and to nanotubes with multi‐equivalents of counterion. The limited cytotoxicity of GA in aqueous media exhibits good biocompatibility.

AbstractThe rapidly evolving synthetic cannabinoid receptor agonist (SCRA) market poses significant challenges for forensic scientists. Since the enactment of a generic ban in China, a variety of new compounds have emerged capable of evading the legislation by carrying new structural features. One recent example of a SCRA with new linker and head moieties is CH‐PIATA (CH‐PIACA, CHX‐PIATA, CHX‐PIACA). CH‐PIATA bears an additional methylene spacer in the linker moiety between the indole core and the traditional carbonyl component of the linker. This study describes detections in 2022 of this new SCRA in the United States, Belgium, and Scottish prisons. CH‐PIATA was detected once in a seized powder by Belgian customs and 12 times in Scottish prisons in infused papers or resin. The metabolites of CH‐PIATA were investigated via in vitro human liver microsome (HLM) incubations and eight metabolites were identified, dominated by oxidative biotransformations. A blood sample from the United States was confirmed to contain a mixture of SCRAs including CH‐PIATA via presence of the parent and at least five of the metabolites identified from HLM incubations. Furthermore, this paper evaluates the intrinsic in vitro cannabinoid 1 and 2 (CB1 and CB2) receptor activation potential of CH‐PIATA reference material and the powder seized by Belgian customs by means of β‐arrestin 2 recruitment assays. Both the reference and the seized powder showed a weak activity at both CB receptors with signs of antagonism found. Based on these results, the expected harm potential of this newly emerging substance remains limited.

AbstractObjectiveThe offspring of US military service members may be at increased risk for eating disorders. However, no epidemiological studies to date have evaluated eating disorder incidence rates and prevalence estimates among military‐dependent youth.MethodThis retrospective cohort study examined eating disorder diagnoses in the military healthcare system (MHS) from 2016 through 2021. Active duty and national guard military‐dependent youth, aged 10–17 years, who received care in the MHS via TRICARE Prime insurance, were identified by one or more ICD‐10 codes indicative of an eating disorder diagnosis (anorexia nervosa, bulimia nervosa, binge‐eating disorder, and other‐specified eating disorders).ResultsDuring the 6‐year surveillance period, 2534 dependents received incident diagnoses of eating disorders, with a crude overall incidence rate of 1.75 cases per 10,000 person‐years. The most common diagnosis was other‐specified eating disorder, followed by anorexia nervosa, bulimia nervosa, and binge‐eating disorder. The crude annual incidence rate of all eating disorder diagnoses increased by nearly 65% from 2016 to 2021. Rates for all diagnoses were highest in 2020 and 2021. Period prevalence estimates were .08% for any eating disorder diagnosis, .01% for anorexia nervosa, .004% for bulimia nervosa, .004% for binge‐eating disorder, and .06% for other‐specified eating disorders.DiscussionThe observed increase in eating disorder diagnoses during the surveillance period appeared to be driven by female dependents. More military dependents experienced a new‐onset diagnosis during the COVID‐19 pandemic compared to previous years. These findings highlight the need for eating disorder screening, identification, and treatment for dependents within the MHS.Public Significance StatementChildren of US military service members may be at increased risk for eating disorders. Results indicate new‐onset eating disorder cases increased 65% from 2016 to 2021, primarily among girls compared to boys. The most diagnosed and fastest growing diagnosis was other‐specified eating disorder. Rates of anorexia nervosa increased following the COVID‐19 pandemic. Findings highlight the need for eating disorder screening, identification, and treatment within the military healthcare system.
