Structural color printing and evaluation based on 3D printing
Authors: He Jundong , Lv Xinguang 
Published: January 2023

Purpose
The purpose of this study is to modify the FDM 3D printer to print with polystyrene (PS) microspheres as the printing material, thus enabling bottom-up structural color printing and evaluating structural color printing.

Design/methodology/approach
This study chose a range of different heated bed temperatures to determine a suitable temperature for accelerating the self-assembly of photonic crystals and printing structural colors on various substrates. In addition, this study enhanced the structural color by doping PS microspheres with different contents of Acid Black 210 dye and evaluated the color-enhanced structural color by eye and spectrophotometer under different light sources.

Findings
The results show that the modified 3D printer can be used for structural color printing, and 50°C is determined as the heated bed temperature. There are significant differences in structural colors when printing under different color backgrounds and material substrates, and corresponding suitable substrates should be selected according to the application. The doping of PS microspheres with varying contents of dye results in different color levels of structural color. As with pigment colors, the visual perception of structural color varies when viewed under different light sources.

Originality/value
This paper proposes to print structural colors low-costly, analyze structural colors under substrate and light source conditions, and expand the structural color gamut by enhancing structural colors, which has positive implications for further research on structural colors as printing colors.
Compressive response of selective laser-melted lattice structures with different strut sizes based on theoretical, numerical and experimental approaches
Authors: Huang Xina , Ding Shoubin , Lang Lihui , Gong Shuili 
Published: January 2023

Purpose
The purpose of this paper is to investigate the effect of strut size on the compressive response for selective laser-melted lattice structure with a body-centered cubic (BCC) unit cell.

Design/methodology/approach
Theoretical analysis and numerical simulation were used to predict the compressive stiffness and strength of the lattice structures with different struts, and compression testing was conducted to validate the predicted results. The effect of strut size on actual porosity was determined with the dry weighting method. Scanning electron microscopy was used to observe the fracture morphologies.

Findings
The actual porosities in all the specimens turned out to be a little lower than the values expected from design. The maximum deviation appears at the strut size of 1.25 mm. The theoretical analysis reveals that the junctions of BCC unit cells are the most loaded points, and the maximum compression resistance load is proportional to the strut size. The stress–strain curves and collapse modes predicted by numerical simulation are in good agreement with the theoretical calculation and experimental results. The compression stress increases monotonously in strut size of 0.50–2.00 mm. The fracture morphologies reflect a transition from a mixed to ductile fracture mechanism. The lattice structure shows a stable plastic deformation without a destructive fracture for the strut size of 2.00 mm.

Originality/value
The findings of this study can provide theoretical and experimental support for the choice of strut size under different stress conditions. In addition, they are conductive to in-depth study of the compressive properties for lattice structures with different geometrical dimensions fabricated by selective laser melting.

Authors: Rahman Sohanur , Kabir Md Nurul , Talukdar Kamrul Huda , Anwar Mumtaheena 
Published: January 2023

Purpose
This study aims to examine the association between national culture and corporate carbon emissions. Specifically, the research explores how firm-level carbon emissions are associated with Hofstede’s four cultural dimensions: power distance, individualism/collectivism, masculinity/femininity and uncertainty avoidance.

Design/methodology/approach
The study examines 36,945 firm-year observations across 39 countries and uses panel regressions to assess the association between firm-level carbon emissions and national culture. This research also uses instrumental variable regression to address the potential endogeneity issues. Alternative proxies for culture are used to test the sensitivity of the findings.

Findings
The findings of this study reveal that power distance and uncertainty avoidance are negatively while individualism and masculinity are positively associated with corporate carbon emissions. The results are robust to the instrumental regressions and alternative measures of culture.

Practical implications
For policymakers, this research highlights the importance of national culture in assessing the efficacy of potential emissions reduction policies, identifying the possible challenges posed by the cultural differences of the targeted groups and designing policy adjustments accordingly. The local culture in which the branches of multinational corporations operate should be considered when the management implements emissions reduction policies for the business units in diverse cultural settings.

Social implications
Aligning emissions reduction policies with regional cultural dimensions has the potential to enhance the effectiveness of corporate and national emissions reduction policies, which can contribute to mitigating global climate change adversities.

Originality/value
This study provides insights into firm-level carbon emissions and Hofstede’s four cultural dimensions in a global setting.
Cities under fire: Crisis communication on home front versus frontline cities' Facebook pages during operation ‘guardian of the walls’
Authors: Yavetz Gal , Bronstein Jenny 
Published: January 2023

AbstractSocial media has been widely adopted by local governments during emergencies and crises and its role as a communication platform has been discussed in various studies on natural hazards, pandemics and terror attacks. However, research in the field has not addressed how municipalities use social media to communicate valuable information during armed conflicts and military operations. The current study examined the ways five major cities in Israel used their Facebook pages to connect to their residents during operation ‘Guardian of the Walls' in 2021. We examined the social media usage and the strategies of these cities during the 12 days of the operation. The findings revealed significant differences between cities that are considered as home front versus frontline regions regarding content type and information dissemination strategies. Additionally, differences regarding content types in terms of sentiment and overall rates of engagement were also identified. These findings highlight the need to further investigate local municipalities' usage of social media during armed conflicts concerning the civil population.

AbstractInjury to the right gastroepiploic artery (RGEA) graft during gastrectomy after coronary artery bypass grafting (CABG) can cause critical coronary failure. A man in his 60s with advanced gastric cancer and a history of CABG was admitted to our hospital. His cardiac blood flow was dependent on RGEA, and a gastrectomy with RGEA preservation was necessary. Robot‐assisted distal gastrectomy with real‐time vessel navigation using indocyanine green (ICG) fluorescence imaging and Da Vinci Firefly technology was planned. Intraperitoneal observation revealed severe adhesions around the graft. Two milliliters ICG (2.5 mg/mL) was injected intravenously, and RGEA was visualized. An RGEA‐preserving robot‐assisted distal gastrectomy was successfully performed. The operation time was 279 minutes, and the blood loss was 5 mL. The postoperative course was good and there were no complications.
Get in and get out: Remodeling of the cellular actin cytoskeleton upon HIV‐1 infection
Authors: Serrano Thomas , Frémont Stéphane , Echard Arnaud 
Published: January 2023

AbstractThe human immunodeficiency virus type 1 (HIV‐1) is an intracellular pathogen whose replication cycle strictly depends on the host cell molecular machinery. HIV‐1 crosses twice the plasma membrane, to get in and to get out of the cell. Therefore, the first and the last line of intracellular component encountered by the virus is the cortical actin network. Here, we review the role of actin and actin‐related proteins in HIV‐1 entry, assembly, budding, and release. We first highlight the mechanisms controlling actin polymerization at the entry site that promote the clustering of HIV‐1 receptors, a crucial step for the virus to fuse with the plasma membrane. Then, we describe how actin is transiently depolymerized locally to allow the capsid to cross the actin cortex, before migrating towards the nucleus. Finally, we review the role of several actin‐binding proteins in actin remodeling events required for membrane deformation and curvature at the viral assembly site as well as for virus release. Strikingly, it appears that common actin‐regulating pathways are involved in viral entry and exit. However, while the role of actin remodeling during entry is well understood, this is not the case during exit. We discuss remaining challenges regarding the actin‐dependent mechanisms involved in HIV‐1 entry and exit, and how they could be overcome.

AbstractAimsTo examine association of liver‐expressed antimicrobial peptide 2 (LEAP2), an endogenous ghrelin antagonist with anorexiant effects, to key cardiometabolic risk factors in people with overweight and obesity.MethodsIn this cross‐sectional study, we sought to identify associations between LEAP2 levels and cardiometabolic risk factors, including body composition (dual X‐ray absorptiometry), insulin and glucose metabolism (oral and intravenous glucose tolerance tests and hyperinsulinaemic‐euglycaemic clamps), plasma lipids and inflammation markers (ELISA and multiplex assays).ResultsIn 65 participants with overweight or obesity (63.1% male, mean age 31.3 ± 8.5 years), LEAP2 levels were associated with total body fat, but not with body mass index or waist‐hip ratio in both univariable and age‐ and sex‐adjusted models (P < 0.05). Higher LEAP2 level was also positively associated with higher insulin secretion in univariable (P = 0.047) and multivariable models adjusted for age, sex and body fat (P = 0.03), but not with fasting glucose levels (P ≥ 0.05). Higher LEAP2 levels were associated insulin resistance (P = 0.07) after adjustment for age and sex, but the association disappeared after an additional adjustment for body fat (P = 0.2). There was an inverse association between LEAP2 levels and nuclear factor kappa‐B (NFκB) activity in the peripheral blood mononuclear cells in age‐, sex‐ and body fat‐adjusted models (P = 0.04). There were no associations with cardiovascular risk factors (lipids, blood pressure) or other inflammation markers.ConclusionsThese results provide important insights into the association between LEAP2 and cardiometabolic health in a high‐risk population of individuals with overweight and obesity. This is a first report of an association between LEAP2 and insulin secretion, insulin sensitivity and NFκB activity. LEAP2 may represent an important potential therapeutic target to promote insulin secretion in people with type 2 diabetes and obesity.
Self‐management interventions for children and young people with sickle cell disease: A systematic review
Authors: Poku Brenda A. , Atkin Karl Michael , Kirk Sue 
Published: January 2023

AbstractBackgroundIncreasing numbers of interventions are being developed to support self‐management for children and young people (CYP) with sickle cell disease (SCD), but no systematic review has systematically synthesized this evidence regarding their characteristics, effectiveness, acceptability and feasibility for all published intervention types.MethodsThe Joanna Briggs Institute guidelines for mixed‐method reviews were followed. A systematic search of eight databases and key journals was conducted from their inception to November 2021. Primary research of self‐management interventions targeting CYP with SCD aged 8–24 years and reporting any health/social outcome and acceptability data were included. Design‐specific standardized critical appraisal instruments were used. Two independent reviewers screened and appraised the articles. A third reviewer resolved disagreements.ResultsOf 1654 articles identified, 38 studies were included. Methodological quality was moderate. Most studies evaluated SCD education, psycho‐behavioural, psychosocial and skills training and/or social support interventions. They appear to demonstrate short‐term improvements in knowledge, social functioning and medical adherence outcomes. Interventions that were multifaceted in content, combined technological platforms and in‐person group‐based formats and involved peers, family and care providers were more acceptable and effective. The long‐term impact of interventions was limited, including CYP's involvement in the intervention development and implementation.ConclusionsThere is inconclusive evidence for any self‐management programme. Nonetheless, support from family, peers and care providers appears to be important for self‐management interventions' effectiveness and acceptability. Future research needs to prioritize CYP involvement in both intervention design and delivery, their wider social context and include CYP with SCD from non‐Black backgrounds.Patient and Public ContributionThree young people with SCD recruited acted as the review advisors. They were formally trained in the review process and involved in every aspect of the review: the design, conduct and interpretation of the findings. CYP involvement in the interventions' development and implementation was analysed as part of the review. This systematic review was conducted as part of a wider research project titled: Understanding fatigue experiences of CYP with SCD to guide the co‐development of a fatigue self‐management intervention. Two of the young advisors involved in the review were also involved in the development of the project funding application.
Insight into the antibacterial activity and mechanism of chitosan caffeic acid graft against Pseudomonas fluorescens
Authors: Lan Weiqing , Du Jintao , Sun Yuqing , Xie Jing 
Published: January 2023

SummaryThe antibacterial mechanism of chitosan‐grafted caffeic acid (CS‐g‐CA) against Pseudomonas fluorescens (P. fluorescens) was studied. The results indicated that the MIC of CS‐g‐CA to P. fluorescens was 1.25 mg/mL, and CS‐g‐CA in MIC could effectively inhibit the growth of bacteria. CS‐g‐CA can greatly destroy the cell membrane of P. fluorescens, enhancing its permeability and leading to the leakage of macromolecular proteins. The results of reactive oxygen species (ROS) and lipid peroxidation activities demonstrated that CS‐g‐CA could destroy the respiratory and metabolic system. According to scanning electron microscope (SEM), CS‐g‐CA can destroy the somatic cells of bacteria, resulting in the leakage of their contents and death by lysis. In addition, thallus movement was inhibited by CS‐g‐CA. Electrophoresis results showed that the DNA of P. fluorescens with CS‐g‐CA treatment was destroyed, which further led to the death of microorganisms. Eventually, the normal growth and reproduction of bacteria were also hindered. These findings suggested that CS‐g‐CA is a promising antimicrobial agent to control P. fluorescens in aquatic products.

AbstractIntroductionThe Heliostar™ ablation system is a novel RF balloon ablation technology with an integrated three‐dimensional mapping system. Here, we describe our early experience and procedural outcomes using this technology for atrial fibrillation catheter ablation.MethodsWe sought to comprehensively assess the first 60 consecutive patients undergoing pulmonary vein isolation using the novel HELISOTAR™ RF balloon technology including procedural outcomes. A comparison of the workflow between two different anaesthetic modalities (conscious sedation [CS] vs. general anaesthesia [GA]) was made. Procedural data were collected prospectively from two high‐volume centers (Barts Heart Centre, UK and University Hospital of Zurich, Zurich). A standardized approach for catheter ablation was employed.ResultsA total of 35 patients had the procedure under CS and the remaining under GA. Mean procedural and fluoroscopy times were 84 ± 33 min and 1.1 min. The median duration of RF energy application was 7 (5–9.8) mins per patient. All veins were successfully isolated, and the median isolation time was 10 (7–15) seconds. Our cohort's rate of procedural complications was low, with no mortality within 30 days postprocedure.ConclusionOur early experience shows that catheter ablation using the Heliostar™ technology can be performed efficiently and safely; however, long‐term data is yet to be established. Low fluoroscopy requirements, short learning curves and use of this technology with CS is possible, including the use of an oesophageal temperature probe.
Lifestyle changes in atrial fibrillation management and intervention
Authors: Yang Lucy , Chung Mina K. 
Published: January 2023

AbstractAtrial fibrillation (AF) is one of the most common arrhythmias in adults, and its continued rise in the United States is complicated by the increased incidence and prevalence of several AF risk factors, such as obesity, physical inactivity, hypertension, obstructive sleep apnea, diabetes mellitus, coronary artery disease, and alcohol, tobacco, or caffeine use. Lifestyle and risk factor modification has been proposed as an additional pillar of AF therapy, added to rhythm control, rate control, and anticoagulation, to reduce AF burden and risk. Although emerging evidence largely supports the integration of lifestyle and risk factor management in clinical practice, randomized clinical trials investigating the long‐term sustainability and reproducibility of these benefits remain sparse. The purpose of this review is to discuss potentially reversible risk factors on AF, share evidence for the impact on AF by modification of these risk factors, and then provide an overview of the effects of reversing or managing these risk factors on the success of various AF management strategies, such as antithrombotic, rate control, and rhythm control therapies.

AbstractBackgroundLesion gaps assessed by late‐gadolinium enhancement magnetic resonance imaging (LGE‐MRI) are associated with the atrial fibrillation (AF) recurrence after pulmonary vein isolation. Animal studies have demonstrated that the catheter‐contact force (CF), stability, and orientation are strongly associated with lesion formation. However, the impact of those procedural factors on the lesion characteristics associated with AF recurrence has not been well discussed.MethodsA total of 30 patients with paroxysmal AF who underwent catheter ablation were retrospectively enrolled. Radiofrequency (RF) applications were performed with 35 W for 30 s in a point‐by‐point fashion under esophageal temperature monitoring. The inter‐lesion distance was 4 mm. The lesions were visualized by LGE‐MRI 3 months postprocedure and assessed by the LGE volume (ml), gap number (GN), and average gap length (AGL [mm]). The gaps were defined as nonenhancement sites of >4 mm. The procedural factors including the catheter‐CF, stability, and orientation were calculated on the NavX system.ResultsSix (20%) of 30 patients had AF recurrences 12 months postablation. A univariate analysis demonstrated that the AGL was associated with AF recurrence (hazard ratio [HR]: 1.20, confidence interval [CI]: 1.03–1.42, p = .02). All AF recurrence were found in patients with an AGL of >7 mm. The catheter‐CF and stability were associated with an AGL of >7 mm, but not the orientation (CF—HR: 0.62, CI: 0.39–0.97, p = .038; stability—HR: 0.8, CI: 0.66–0.98, p = .027).ConclusionsRF ablation with a low CF and poor catheter stability has a potential risk of creating large lesion gaps associated with AF recurrence.

AbstractInstructionWe hypothesized that real‐time simultaneous amplitude frequency electrogram transform (SAFE‐T) during sinus rhythm (SR) is able to identify and characterize the drivers of atrial fibrillation (AF) in nonparoxysmal (NP) AF.MethodsTwenty‐one NPAF patients (85.71% males, mean age 52 years old) underwent substrate mapping during SR (SAFE‐T and voltage) and during AF (complex fractionated atrial electrograms [CFAE] and similarity index [SI]). After pulmonary veins isolation, extensive substrate ablation was performed with the endpoint of procedural termination or elimination of all SI sites (>63% similarities). Sites with procedural termination and non‐termination sites were tagged for postablation SR analysis using SAFE‐T.ResultsIn 74 CFAE sites identified (average of 3 ± 2 sites per person), 28 (37.84%) were identified as termination sites demonstrating a high SI compared with the non‐termination sites (80.11 ± 9.57% vs. 45.96 ± 13.38%, p < .001) during AF. During SR, these termination sites have high SAFE‐T values and harbor a highly resonant, localized, repetitive high frequency components superimposed in the low frequency components compared with non‐termination sites (5.70 ± 3.04 vs. 1.49 ± 1.66 Hz·mV, p < .001). In the multivariate analysis, the termination sites have higher SAFE‐T and SI value (p < .001).ConclusionAF procedural termination sites harbored signal characteristics of repetitive, high frequency component of individualized electrogram during SR, which can be masked by the low frequency fractionated electrogram and are difficult to see from the bipolar electrogram. Thus, SAFE‐T mapping is feasible in identifying and characterizing sites of AF drivers.
