3D seismic analysis of complex faulting patterns and fluid escape features and their relation to Late Cenozoic Magmatism in the Bass Basin, offshore SE Australia
Authors: Velayatham Tayallen , Holford Simon , Bunch Mark , King Rosalind , Schofield Nick
Published: February 2024

Igneous intrusions in sedimentary petroleum basins are often perceived as having a negative impact on the elements of the petroleum system, though the impact of intrusion-related deformation features on petroleum systems and broader geoenergy applications is not well understood. In this study, we use 3D seismic reflection data to document a variety of deformation styles that are spatially and temporally associated late Cenozoic magmatic activity in the Bass Basin, offshore southeastern Australia; three types of normal fault systems (conjugate faults, concentric faults, radial faults) and fluid escape pipes. These deformation features occur in the overburden up to ∼600 m above underlying igneous intrusions, within the Eocene to Miocene Demons Bluff and Torquay formations. The conjugate faults bound graben and are interpreted to have formed in response to underlying dyke intrusions. The radial faults are interpreted to have formed in response to overburden uplift, though the link between these and associated igneous activity is less clear. We identify 101 fluid escape features that show variation in both the morphology of their surficial depressions and of the seismic reflection characteristics of their infilling deposits. These features are interpreted to be hydrothermal or volcanic vents with underlying pipe-like feeders, depending on their spatial association with adjacent or underlying igneous intrusions. The concentric fault systems are associated with surficial depressions, and quantitative analysis of reflection sags within these depressions suggest that they are a result of subsurface subsidence in response to formation of maar-craters. The intrusion-related deformation features documented in this study may have multiple effects on working petroleum systems, such as providing secondary fluid flow pathways that can either reduce seal integrity, or enabling migration of fluids into shallower reservoirs.

Authors: Amini Razieh , Moradi Shadi , Najafi Rezvan , Mazdeh Mehrdokht , Taherkhani Amir
Published: February 2024

Background. Neurological disorders like Alzheimer’s disease (AD) and Parkinson’s disease (PD) manifest through gradually deteriorating cognitive functions. An encouraging strategy for addressing these disorders involves the inhibition of precursor-cleaving enzyme 1 (BACE1). Objectives. In the current research, a virtual screening technique was employed to identify potential BACE1 inhibitors among selected herbal isolates. Methods. This study evaluated 79 flavonoids, anthraquinones (AQs), and cinnamic acid derivatives for their potential blood–brain barrier (BBB) permeability. Using the AutoDock 4.0 tool, molecular docking analysis was conducted to determine the binding affinity of BBB permeable compounds to the BACE1 active site. Molecular dynamics (MD) simulations were performed to assess the stability of the docked poses of the most potent inhibitors. The interactions between the most effective plant-based inhibitors and the residues within the BACE1 catalytic site were examined before and after MD simulations. Results. Ponciretin, danthron, chrysophanol, and N-p-coumaroyltyramine were among the highest-ranking BACE1 inhibitors, with inhibition constant values calculated in the nanomolar range. Furthermore, during 10 ns simulations, the docked poses of these ligands were observed to be stable. Conclusion. The findings propose that ponciretin, danthron, chrysophanol, and N-p-coumaroyltyramine might serve as potential choices for the treatment of AD and PD, laying the groundwork for the creation of innovative BACE1 inhibitors.
NETosis Secondary to the Use of Levamisole-Adulterated Cocaine: A Likely Underlying Mechanism of Vasculopathy
Authors: Osorio Manuela , Velásquez Isabel , Vargas Ruben , Vanegas-García Adriana , Rojas Mauricio , Vásquez Gloria , Muñoz-Vahos Carlos
Published: February 2024

Background. Since 2010, several cases of a new vasculopathy induced by the use of levamisole-adulterated cocaine (LAC) have been reported. This vasculopathy is characterized by retiform purpura, earlobe necrosis, multisystem compromise, and multiple autoantibodies. Given its similarity to antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, LAC-associated vasculopathy is postulated to be mediated by pathophysiologic processes resulting from neutrophil cell death by NETosis, a phenomenon previously described in ANCA vasculitis. This study tries to establish the presence of NETosis induced by cocaine, levamisole, or both. Methodology. Neutrophils were isolated from the peripheral blood of healthy controls by Ficoll-Hystopaque density gradient centrifugation followed by dextran sedimentation. Cell viability and purity were evaluated by flow cytometry after staining with PI/DiOC6 and labeling with fluorescent anti-CD45/anti-CD3 monoclonal antibodies (mAbs), respectively. Neutrophils were exposed to levamisole, cocaine, a cocaine-levamisole mixture, and sera pools from healthy controls and patients with LAC-associated vasculopathy. NETosis was then assessed by flow cytometry after staining cells with Sytox Green, Hoechst-33342, and fluorescent antineutrophil elastase (NE) and antimyeloperoxidase (MPO) mAbs. In addition, NETosis was morphologically confirmed by fluorescence microscopy. Proinflammatory cytokine levels in culture supernatants and reactive oxygen species (ROS) synthesis were determined by flow cytometry. The involvement of calcium and muscarinic receptors in cell death induction was evaluated in parallel experiments carried out in the presence of 1,2-bis (o-aminophenoxy) ethane-N, N, N′, N′-tetraacetic acid (BAPTA) and hyoscine butylbromide (HBB), their respective inhibitors. Results. Cocaine, levamisole, and a cocaine-levamisole mixture induced neutrophil cell death. DNA/MPO extrusion and cell morphology patterns were consistent with NETosis. Neither proinflammatory cytokines nor ROS behaved as proNETotic factors. Preliminary results suggested that muscarinic receptors and calcium-dependent signals were involved in LAC-induced NETosis. Conclusions. Cocaine, levamisole, and a cocaine-levamisole mixture can induce NETosis through mechanisms involving muscarinic receptors and calcium-dependent pathways.
Genetic Information to Share with Parents when Newborn Screening Reveals the Presence of Sickle Cell Trait
Authors: Elenga Narcisse
Published: February 2024

The primary purpose of newborn screening for sickle cell disease is to diagnose the disease before the appearance of symptoms and to initiate early treatment. To answer the question “What genetic information needs to be communicated to parents when newborn screening reveals the presence of a sickle cell trait,” we conducted a survey using a self-administered online questionnaire. We received responses from 122 healthcare workers and members of sickle cell disease associations, in France and French overseas departments. Our results showed similar positions on this issue. The information conveyed is not consistent and is the result of grassroots initiatives. The negative consequences generated by this information could be reduced when this information is delivered by a multidisciplinary team, within the framework of a dedicated consultation. This information on sickle cell trait status should be given in at least three key periods: the neonatal period, early adolescence, and later adolescence, when reproductive implications become important. Neonatal screening programs should develop systems that allow referring physicians to easily access the results of neonatal screening electronically. Harmonization of practices should allow a better analysis of the consequences of this counselling on family projects.

Published: February 2024

Kajian komunikasi Indonesia dan Asia (Timur) sejak lama didominasi perspektif Eropa dan Amerika Serikat (Barat). Kondisi ini berdampak pada penggunaan perpektif komunikasi yang tidak kontekstual dengan realitas lokus penggunaannya di Timur karena mempunyai kultur yang berbeda dengan Barat. Perspektif komunikasi Barat dengan budaya individualistik tentu tidak dapat dipakai di Indonesia dan Asia dengan budaya kolektif (gotong royong). Oleh sebab itu, wacana yang dibangun oleh penulis dalam buku Komunikasi Perspektif Indonesia dan Asia ini sangat berarti sebagai diskursus bersama dalam mengemukakan komunikasi berperspektif Timur. Penulis tidak sebatas menyajikan fenomena komunikasi dengan cara pandang orang Indonesia atau Asia, tetapi lebih jauh menguraikan ihwal perjalanan pemikiran dan autentisitas komunikasi perpektif Timur. Secara sistematis, pembaca akan menemukan pembabakan di satu sisi tentang pentingnya komunikasi perpektif Timur dan di sisi lain perihal kelemahaman komunikasi perpektif Barat. Lebih-lebih, wacana dalam buku ini digubah dengan literatur yang lengkap disertai kontekstualitas penerapannya di Indonesia dan Asia. Oleh karena itu, teruntuk setiap pembelajar Ilmu Komunikasi dan terkhusus pengkaji Komunikasi Perspektif Indonesia dan Asia, buku ini teramat penting untuk dilewatkan.

Discrimination and Mental Health Outcomes Among 1.5- and 2nd-Generation Muslim College Students
Authors: Hailes Helen P. , Tummala-Narra Pratyusha
Published: February 2024

In the United States, Muslims live in a climate of heightened Islamophobia and racism. While research has indicated the negative mental health impacts of discrimination among Muslim Americans, the relationship between specific types of discrimination and mental health among 1.5- and 2nd-generation racial minority immigrant-origin Muslim American emerging adults remains unclear. This study, with a sample of 128 1.5- and 2nd-generation, racial minority, immigrant-origin Muslim American college students, explored the associations between (a) everyday experiences of discrimination, (b) campus racial climate, and (c) perceived Islamophobia in the broader culture and symptoms of depression and anxiety. We further examined whether perceived social support and ethnic identity moderated these associations. Findings revealed that everyday experiences of discrimination were significantly associated with symptoms of both depression and anxiety, and campus racial climate and broader perceptions of Islamophobia were significantly associated with anxiety but not depressive symptoms. Although stronger ethnic identity was associated with fewer depressive symptoms and higher perceived social support was associated with fewer anxiety and depressive symptoms, neither buffered against the negative effects of discrimination on mental health symptoms. The implications of the findings for culturally informed interventions and resources for Muslim American college students are discussed.
Experimental evaluation of a machine learning approach to improve the reproducibility of network simulations
Authors: Liang Luke , Phan Hieu , Giabbanelli Philippe J
Published: February 2024

A stochastic network simulation is verified when its distribution of outputs is aligned with the ground truth, while tolerating deviations due to variability in real-world measurements and the randomness of a stochastic simulation. However, comparing distributions may yield false positives, as erroneous simulations may have the expected distribution yet present aberrations in low-level patterns. For instance, the number of sick individuals may present the right trend over time, but the wrong individuals were infected. We previously proposed an approach that transforms simulation traces into images verified by machine learning algorithms that account for low-level patterns. We demonstrated the viability of this approach when many simulation traces are compared with a large ground truth data set. However, ground truth data are often limited. For example, a publication may include few images of their simulation as illustrations; hence, teams that independently re-implement the model can only compare low-level patterns with few cases. In this paper, we examine whether our approach can be utilized with very small data sets (e.g., 5–10 images), as provided in publications. Depending on the network simulation model (e.g., rumor spread, cascading failure, and disease spread), we show that results obtained with little data can even surpass results obtained with moderate amounts of data at the cost of variability. Although a good accuracy is obtained in detecting several forms of errors, this paper is only a first step in the use of this technique for verification; hence, future works should assess the applicability of our approach to other types of network simulations.
Planning for Program Evaluation Improves Implementation and Assessment
Authors: Tower Leslie E. , Patrick Julie Hicks
Published: February 2024

This article offers a general approach to plan and implement an educational program by illustrating the evaluation process and data from the AGE-ADAR Scholars Program. A well-designed program evaluation will also include a plan for stakeholder dissemination. We adapted a framework from the Centers for Disease Control and Prevention which includes hard and soft outcomes. Hard outcomes include improved academic metrics, including test scores and graduation rates. Soft outcomes include changes in students’ attitudes, particularly those related to reduced ageism as well as readiness to pursue graduate study. While our hard and soft outcomes suggest that the ADAR program is effective in increasing interest in rural health disparities and aging research, we are hopeful that our impact will continue to enrich the lives of our students and the communities in which they live and work.
A Case of Squamoid Eccrine Ductal Carcinoma of the Auricle Mimicking Perichondritis

Published: February 2024

The subtype of eccrine carcinoma known as squamoid eccrine ductal carcinoma (SEDC) is rare; only 38 cases, including only 6 cases in the ear, have been documented in the literature. This may be the first case to focus on the fact that SEDC, located within the dermal and subcutaneous layers, spares the epidermis histopathologically, which can cause clinicians to confuse SEDC with acute perichondritis.

Published: February 2024

This paper focuses on improving the ergonomics of industrial workers. It addresses the critical implications of poor ergonomics, which can lead to musculoskeletal disorders over time. A novel methodology for a path-planning algorithm designed for human–robot collaboration was introduced to tackle this challenge. The algorithm’s essential contribution lies in determining the most ergonomic path for a robot to guide a human’s hand during task execution, facilitating a transition toward an optimized body configuration. The algorithm effectively charts the ergonomic path by adopting a Cartesian path-planning approach and employing the cell decomposition method. The methodology was implemented on a dataset of ten individuals, representing a diverse group of male and female subjects aged between 20 and 35, with one participant being left-handed. The algorithm was applied to three different activities: “stacking an item,” “taking an object from a shelf,” and “assembling an object by sitting over a table.” The results demonstrated a significant improvement in the REBA score (as a measure of ergonomics condition) of the individuals after applying the algorithm. This outcome reinforces the efficacy of the methodology in enhancing the ergonomics of industrial workers. Furthermore, the study compared the performance of A* with three heuristic functions against Dijkstra’s algorithm, aiming to identify the most effective approach for achieving optimal ergonomic paths in human–robot collaboration. The findings revealed that A* with a specific heuristic function surpassed Dijkstra’s algorithm, underscoring its superiority in this context. The findings highlight the potential for optimizing human–robot collaboration and offer practical implications for designing more efficient industrial work environments.
The Influence of Tibial Tubercle–Sparing Slope-Reducing Osteotomy on Patellar Height in Patients Undergoing Revision ACL Reconstruction
Authors: Guy Sylvain , Saithna Adnan , Ferreira Alexandre , Carrozzo Alessandro , Vieira Thais Dutra , Ollivier Matthieu P. , Sonnery-Cottet Bertrand
Published: February 2024

Background:

A posterior tibial slope (PTS) >12° is an independent risk factor for anterior cruciate ligament (ACL) graft rupture, and a high tibial osteotomy (HTO) for slope correction can help avoid it. Management of patellar height is of major concern when performing HTO.

Purpose:

To evaluate the effect of tibial tubercle–sparing anterior closing-wedge osteotomy on patellar height in revision ACL reconstruction (ACLR).

Study Design:

Case series; Level of evidence, 4.

Methods:

Patients who underwent arthroscopic revision ACLR combined with retro–tibial tubercle anterior closing-wedge HTO (ACW-HTO) between January 1, 2016, and March 31, 2021, were assessed for eligibility. Patellar height was measured on full weightbearing lateral radiographs according to the Insall-Salvati index (ISI) and Caton-Deschamps index (CDI) or frontal radiographs using the femoral patellar height index. The PTS was evaluated using the proximal anatomic axis of the tibia on standard short lateral radiographs. The delta (postoperative – preoperative) and the ratio (preoperative/postoperative) of the 3 patellar height indices and PTS were calculated. Preoperative and postoperative patellar heights were compared using independent t tests for each index. Also investigated was whether patients changed patellar height category (baja, normal, or alta) after slope osteotomy.

Results:

Among 475 revision ACLRs, 47 tibial tubercle–sparing ACW-HTOs were retained for analysis. No significant difference in patellar height was found between pre- and postoperative radiographs regardless of the index (preoperative – postoperative) (ISI: 1.0 ± 0.2 – 0.9 ± 0.2, P = .1729; CDI: 1.0 ± 0.2 – 1.0 ± 0.2, P = .4034; femoral patellar height index: 1.5 ± 0.2 – 1.5 ± 0.2; P = .5130). Fifteen patients (31.9%) exhibited a postoperative change in their patellar height category when measured by the ISI (6 moved up a category, 9 moved down one), and 18 patients (38.3%) changed category according to the CDI (10 moved up a category, 8 moved down one). No significant difference was found between pre- and postoperative patellar height among these patients (ISI: P = .2418; CDI: P = .3005).

Conclusion:

Changes in patellar height ratio are common after tibial tubercle–sparing ACW-HTO in patients undergoing revision ACLR. The clinical effect of these changes is unknown, and further study is needed to investigate whether they may result in patellofemoral symptoms.
The effect of incentive policies on the diffusion of construction and demolition waste recycling: A government perspective
Authors: Hua Chunxiang , Chen Linyan , Liu Chenyu , Yang Chenxi
Published: February 2024

Construction and demolition (C&D) waste recycling plays a significant role in waste reduction and carbon reduction, which is critical for sustainable development. However, due to various limitations such as financial problems, C&D waste recycling industry is not well developed in developing countries. To address this problem, this study combines complex network theory and evolutionary game theory to analyse the diffusion of C&D waste recycling behaviour among enterprises under governmental incentive policies within a complex network context. The results demonstrate that the size of the network has limited effects on behaviour diffusion in Watts–Strogatz small-world network. Additionally, the study highlights the clear impact of governmental incentive probability, initial rate and connection degree on the diffusion path. By quantitatively investigating the effects of incentive tools, this study contributes to the knowledge of C&D waste management and provides valuable implications for stakeholders seeking to promote the diffusion of C&D waste recycling.

Design

Randomized parallel group trial.

Setting

A public outpatient health center in Brazil.

Subjects

Women employees (included: n = 29; lost to follow-up: n = 1; analyzed: n = 28).

Interventions

8 weeks of gamified (n = 15) or nongamified (n = 13) interventions, consisting of health lectures, nutritional counseling, and supervised exercise training. The gamified group was divided into teams that received points based on completion of health goals/tasks.

Measures

Anthropometric, cardiometabolic and physical fitness parameters.

Analysis

Two-way ANOVA with repeated measures (group vs. time), and Bonferroni post hoc tests.

Results

Body mass (-1.5 ± 1.5 kg), waist circumference (-1.6 ± 3.0 cm), HbA1C (-.2 ± .3%), triglycerides (-21.5 ± 48.2 mg/dl), systolic (-11.1 ± 7.9 mmHg) and diastolic (-7.1 ± 5.8 mmHg) blood pressure, as well as sit and reach (3.9 ± 3.0 cm) and six-minute walking (56 ± 37 m) performance improved ( P < .05) only after the gamified intervention. Sit-to-stand performance improved after both the gamified (-1.18 ± 1.24 s) and nongamified (-1.49 ± 1.87 s) interventions.

Conclusion

The gamified intervention was more effective than the nongamified intervention for improving cardiometabolic and physical fitness parameters, suggesting that gamification may be an effective tool for promoting health in healthcare worker women.
How do Teleworkers Relieve Negative Emotions to Improve Job Performance Through Enterprise Social Media? The Conservation of Resources Theory View
Authors: Ren Xu , Hao Yali , Xu Jing
Published: February 2024

The primary aim of this paper is to study the impact of teleworkers’ psychology on their job performance and how teleworkers relieve negative emotions to improve job performance through enterprise social media (ESM) from the conservation of resources theory perspective. An online survey was sent to 835 teleworkers from industries such as finance, automobile, IT, construction, and logistics from March to May 2022 in China. Useful data from 218 respondents were collected and analyzed to test the hypothesized relationships by partial least squares-structural equation modeling (PLS-SEM) method. The findings show that family-to-work conflict and social isolation positively influence employees’ emotional exhaustion and emotional exhaustion further negatively influences their job performance. The visibility affordance and association affordance of ESM can reduce family-to-work conflict and social isolation, thus reducing teleworkers’ emotional exhaustion. The employees’ psychological resilience negatively moderates the positive effects which family-to-work conflict and social isolation have on emotional exhaustion. This paper studies the relieving effects of ESM affordance on teleworkers’ emotional exhaustion and reveals their defending mechanism for avoiding entering into the negative psychological state. Furthermore, this paper supplies beneficial practical suggestions for managers and teleworkers to improve job performance when working from home.
Immune Thrombocytopenic Purpura and Intracranial Stenting
Authors: Pathan Sophia
Published: February 2024

Patients with immune thrombocytopenic purpura (ITP) presenting with indications for dual antiplatelet therapy (DAPT) can be difficult to manage due to the precarious balance of managing the need for increased platelet counts as well as inhibition of platelet activity. This case represents a 65 year old woman with ITP who presented with a bilateral subarachnoid hemorrhage secondary to a left ophthalmic aneurysm that required placement of a pipeline embolization device (PED) necessitating DAPT. After treatment of her ITP with pulse dexamethasone for four days, she was safely discharged on one month of DAPT with aspirin and ticagrelor then switched to aspirin monotherapy without any immediate complications. During her period of DAPT, she did not receive additional medical treatment for her ITP. This case successfully presents a high-risk ITP patient requiring DAPT for a neurosurgical procedure and illustrates that these patients can be safely and successfully treated with DAPT once their ITP is stabilized.
Dynamic analysis of short-fiber reinforced composite nanobeams based on nonlocal strain gradient theory
Authors: Gul Ufuk
Published: February 2024

This study deals with the dynamic behavior of short-fiber reinforced composite nanobeams. It is assumed that short-fibers are aligned or randomly distributed in the composite nanobeams. Nonlocal strain gradient theory is applied to composite nanobeam mechanics including Euler–Bernoulli and Timoshenko beam models. The transverse vibration of these composite nanobeams is investigated for various boundary conditions. Approximate Ritz method is used for obtaining the natural frequencies of short-fiber reinforced composite nanobeams. In addition to vibration analysis, wave propagation in short-fiber reinforced composite nanobeams is investigated and wave dispersion relations are analytically obtained for both Euler-Bernoulli and Timoshenko beam models. The vibration and wave dispersion results of short-fiber reinforced composite nanobeams are obtained for aligned and randomly distributed cases. The results obtained from this paper showed that there is no significant difference between the aligned and randomly oriented short-fiber composite nanobeams. This provides great convenience to designers where it is not possible to orient the reinforcement material in composites. The present study may be useful for the mechanical analysis and design of micro/nano-electromechanical systems (MEMS/NEMS), nanoprobes, nanosensors, nanoactuators, and atomic force microscopes.
Optimization of prepreg compression molding process for production of structures with recycled carbon fibers
Authors: Minosi Stefania , Buccoliero Giuseppe , Araganese Michele , Raganato Umberto , Tarzia Antonella , Corvaglia Stefano , Gallo Nicola
Published: February 2024

Carbon fibers are widely used in a growing number of industrial sectors. Their high strength to weight ratio makes carbon fibers suitable for high-value-added applications. However, significant environmental and economic problems are related to composite waste disposal and consumption of non-renewable resources for their production. European legislation has imposed more controls on composite materials waste management. Consequently, development of processes for the recovery of the added value of wastes, instead of its simple disposal, is crucial to promoting the application of EU requirements and the realization of a circular economy model. Currently, thermal processes represent the most promising technology in this direction. Thermal processes include pyrolysis, fluidized bed pyrolysis, and microwave-assisted pyrolysis, but only pyrolysis is implemented on an industrial scale in Europe because of its economic viability and technical feasibility. Although the recovery of carbon fibers has reduced cost, compared to virgin fibers, length, orientation, and sizing of the fibers are lost. In this context the challenge is to realize composites reinforced with reclaimed fibers that can compete economically and in terms of mechanical performance with composite with virgin fibers. In this work, prepreg compression molding technique was used to produce a window frame with non-woven fabrics of recycled carbon fibers impregnated with a fast-curing resin. The fibers were coated with a sizing developed by CETMA and compatible with fast-curing epoxy resin.
A preview SMC driver modeling and simulation for the B-train doubles
Authors: Deng Zhaowen , Wang Junzhu , Zhao Youqun , Gao Wei , Zhang Shuqian , Wang Baohua , Chen Yufeng
Published: February 2024

B-train doubles have existed a greater risk of causing accidents. The research on the driver model for combination vehicles is crucial to the active safety control of B-train doubles. The direction control of the driver model forms an invaluable part of the closed-loop simulation of the human-vehicle-road system. Meanwhile, studies of driver models for long combination vehicles (LCVs) are limited. Driver modeling for the articulated heavy vehicle (AHV), a preview driver model for B-train doubles, has been proposed, on the basis of Sliding Mode Control (SMC), considering the low-speed path-tracking and high-speed stability, with the constant speed approach rate and optimal approach rate of the SMC, respectively. The simulation proved that, the proposed driver model can significantly eliminate the chattering phenomena of the front wheel angle, enhance the lateral stability of the B-train doubles, and decrease in peak magnitude of lateral acceleration and yaw angular velocity, and achieve better path following ability.
Müller-Weiss Disease: Midfoot Arthrodesis in Reduction vs Malreduction
Authors: Bai Wenbo , Xu Jingcheng , Zhang Hongning , Li Xue , Zou Yunxuan , Shen Guodong , Zhu Yongzhan
Published: February 2024

Background:

Midfoot arthrodesis is regarded as the main surgical approach for treating Müller-Weiss disease (MWD). This study aimed to investigate the incidence of postoperative pain during MWD treatment through midfoot reduction or malreduction during arthrodesis and to explore the factors influencing postoperative pain in patients with MWD.

Methods:

A total of 67 patients with MWD were recruited and divided into two groups according to whether midfoot alignment was reduced: reduction group ( n = 38) and malreduction group ( n = 29). Demographic characteristics before the operation and at the last follow-up, as well as clinical and radiographic parameters, were compared between the two groups. Clinical parameters included the American Orthopaedic Foot & Ankle Society score and visual analog scale score, whereas radiographic parameters included the calcaneal pitch angle, lateral Meary’s angle, talometatarsal-1 angle dorsoplantar (TMT1dp), talocalcaneal angle dorsoplantar (Kite angle), talonavicular coverage angle, and medial navicular pole extrusion. Postoperative complications and incidence of midfoot pain were evaluated at the last follow-up visit.

Results:

The reduction group exhibited better clinical and radiological parameters, including the TMT1dp and medial navicular pole extrusion, than the malreduction group at the last follow-up (all P < .05). However, the calcaneal pitch angle, lateral Meary’s angle, Kite angle, and talonavicular coverage angle did not significantly differ between the two groups (all P > .05). The overall incidence of midfoot pain was 26.4%. The reduction group showed a lower incidence of medial pain than the malreduction group (15.7% vs. 40.0%, P < .05). Regression analysis revealed that midfoot abduction, represented by the TMT1dp, was a critical factor for midfoot arthrodesis failure and that medial navicular pole extrusion was not correlated with postoperative midfoot pain.

Conclusion:

Midfoot reduction arthrodesis yields better clinical outcomes than malreduction arthrodesis. The TMT1dp, representing midfoot abduction, is a key factor for midfoot arthrodesis failure. The extruded medial navicular bone may not affect postoperative medial midfoot pain.

Correlation Between Life Satisfaction and Symptoms of ADHD in Dental Students: The Mediation of Resilience
Authors: Sun Yuwei , Miao Lei , Chen Siying , Piao Zhenya , Tong Chi
Published: February 2024

Objective:

This study explores the correlation between life satisfaction and ADHD symptoms. It also discusses whether resilience mediates the correlation between ADHD symptoms and life satisfaction.

Method:

We surveyed 297 dental students. A total of 291 completed a self-report scale consisting of the Adult ADHD Self-Report Scale, Wender Utah Rating Scale, Life Satisfaction Scale, and Conner–Davidson Resilience Scale. The study used hierarchical linear regression analysis, resampling, and asymptotic strategies for data processing.

Results:

The ADHD screening results of the self-report scale were positive for 6.87% of the students. This positive rate differed among participants of diverse ages and varying paternal education levels. ADHD symptoms were negatively correlated with life satisfaction and resilience. Life satisfaction was observably positively associated with resilience. Resilience serves as a mediating role between life satisfaction and the two symptoms of ADHD.

Conclusion:

Resilience intervention programs can enhance the life satisfaction of dental students, especially those with positive ADHD symptoms screening.
The Cutler-Beard flap for upper eyelid reconstruction: Surgical indications revisited
Authors: Franzolin Elia , Quaranta Leoni Flavia , Quaranta Leoni Francesco M.
Published: February 2024

Purpose

To present the long-term outcome of the Cutler-Beard two-stage technique in patients with large full-thickness upper eyelid defects after tumor excision.

Methods

The medical records of 24 patients with large full-thickness upper eyelid defects reconstructed with the Cutler-Beard technique from January 2000 to January 2021 were retrospectively reviewed. All the defects involved ≥ 60% of the horizontal length of the upper eyelid and extended vertically for at least 15 mm from the eyelid margin. Patients with follow-up < 24 months were excluded. Long-term postoperative complications, functional outcome, and patient's satisfaction at the end of the follow-up were evaluated.

Results

Patients’ age ranged from 36 to 88 (mean 66.0  ±  10.7 years) and 58.3% were females. Seven patients (29.2%) had had previous eyelid surgeries. The most common diagnosis was basal cell carcinoma (62.5%), followed by sebaceous gland carcinoma (12.5%), squamous cell carcinoma (8.3%), and Merkel cell carcinoma (8.3%). The mean duration of follow-up was 53.0  ±  16.9 months. Eleven patients (45.8%) developed upper eyelid entropion: 9 were treated conservatively with a therapeutic contact lens, 2 patients required a third operating stage. Most patients achieved a satisfactory functional and aesthetical outcome at the end of the follow-up.

Conclusions

Although non-bridging techniques are usually favored to reconstruct large upper eyelid defects, the Cutler-Beard bridge flap is a valuable technique in case of large horizontal defects where the vertical gap is greater than 15 mm. Further surgical steps are rarely necessary; however, alternative techniques should be considered following excision of highly malignant tumors.

Published: February 2024

Purpose

Aim of the study was to evaluate the efficacy of dexamethasone (DEX) 0.7 mg intravitreal implant in patients with diabetic macular edema (DME) and serous retinal detachment (SRD), and to study the prognostic factors on a follow up of 12 months.

Methods

Forty eyes of twenty- six patients with centre involving DME and SRD, who underwent DEX implant, were enrolled. Best-corrected visual acuity (BCVA), Swept source OCT imaging and intraocular pressure were evaluated. Central macular thickness (CMT), vitreomacular adhesion (VMA), disorganization of retinal inner layers (DRILs), hyperreflective dots (HRD), SRD and ellipsoid zone (EZ) disruption were included in the analysis at baseline and 12 months after implant.

Results

According to our parametric analysis, at 12 months, BVCA improvement from 48.6 ± 23.4 letters to 53.3 ± 24.5 letters was statistically significant ( p = 0.04), CMT decreased from 460 ± 99.52 μm to 322.9 ± 117 μm. The presence at baseline of VMA ( p = 0.01), EZ disruption ( p = 0.03) and DRILs ( p = 0.04), were associated with poor BCVA improvement at the end of follow-up.

Conclusion

In conclusion, OCT biomarkers can be considered significant prognostic factors for treatment outcome in patients with DME undergoing DEX intravitreal implant.

Published: February 2024

Diabetes distress (DD) is a negative psychosocial response to living with type 2 diabetes mellitus (T2DM). We sought insight into Veterans’ experiences with DD in the context of T2DM self-management. The four domains in the Diabetes Distress Scale (i.e. regimen, emotional, interpersonal, healthcare provider) informed the interview guide and analysis (structural coding using thematic analysis). The mean age of the cohort ( n = 36) was 59.1 years (SD 10.4); 8.3% of patients were female and 63.9% were Black or Mixed Race; mean A1C was 8.8% (SD 2.0); and mean DDS score was 2.4 (SD 1.1), indicating moderate distress. Veterans described DD and challenges to T2DM self-management across the four domains in the Diabetes Distress Scale. We found that (1) Veterans’ challenges with their T2DM self-management routines influenced DD and (2) Veterans experienced DD across a wide range of domains, indicating that clinical interventions should take a “whole-person” approach.

Validation of the satisfaction with life scale for Korean older adults using item response theory
Authors: Lee Kyeongwon
Published: February 2024

As Korea is rapidly becoming an aging society, people are increasingly interested in the life satisfaction of the older adults. Therefore, the need for a tool that can precisely measure the life satisfaction of the older adults in Korea is also increasing. In this study, SWLS, which has been widely used to measure life satisfaction, was applied to Korean older adults. This study analyzed the life satisfaction of the older adults using item response theory that can supplement the limitations of existing research methods. Data from 3543 older adults who responded to the 2021 Korean Happiness Survey. As a result of the analysis, it was found that the goodness of fit of item 5 exceeded the standard value, and item 4 functioned differentially between the young-old and old-old. Based on the results of this study, it presented an empirical basis for the application of SWLS to the older adults.
Implications of dispositions for foreign language writing: The case of the Arabic–English learner

Individual differences matter in foreign language writing. Yet, little information exists on female students in Saudi Arabia, a patriarchal society that is being re-engineered to foster gender equity. This study asked whether particular psychological dispositions can account for the performance in English composition of STEM (science, technology, engineering, and mathematics) and non-STEM Saudi female students (i.e. an understudied population whose first language is Arabic). Examined were dispositions such as anxiety, which was expected to be detrimental to attainment, and self-efficacy and emotional intelligence, which were expected to be beneficial. A sample of 430 Saudi female students for whom English was their second language was surveyed. Students had completed a required English composition course the previous semester. Cluster analysis illustrated three distinct groups of students. Students who did not report anxiety were either STEM or a subsection of non-STEM students. The remaining non-STEM students reported anxiety as well as lower self-efficacy, emotional intelligence, and writing attainment than the other two groups. Findings suggest that, within this particular understudied population, consideration of individual differences can inform the selection of remedies for at-risk students in English composition courses.
Estimation of greenhouse gas emissions from ships registered in South Korea based on activity data using the bottom-up approach

Published: February 2024

The shipping sector is one of the major contributors to greenhouse gas (GHG) emissions. We aimed to calculate GHG emissions categorized by ship type for all vessels registered in South Korea. Hence, for the first time in South Korea, a bottom-up method based on ship activity data was employed, estimating energy consumption and emissions by ship type. Data from ships registered from 2019 to 2021 were collected and reclassified by ship type, and operational profiles were developed. Based on these profiles, the emissions of major GHGs, including CO2, CH4, and N2O, were estimated for the 3-year period. Cargo ships accounted for the highest percentage of annual fuel consumption, approximately 62.7%–64.7% of the total fuel consumption for all ships. The GHG emissions were calculated to be an average of 4.644 million tonCO2e, which is approximately 6.5 times higher than those from oil tankers (0.710 million tonCO2e), the second-highest emitter. This highlights the need for intensified GHG reduction measures specifically targeting cargo ships, providing clear evidence for prompt and enhanced implementation. The research findings are expected to be utilized as substantiated data for developing specific and systematic GHG reduction policies tailored to each ship type.
