The Impact of Social Media Use Among Millennial Couples
Authors: Owens Anna , Beattie Erin , Irvine Taylor
Published: October 2024

Social media use (SMU) among millennials (i.e., persons born between 1981 and 1996) is considered a hallmark behavior, with nearly 79% of individuals in this age bracket reportedly using social media multiple times a day. Despite the potential benefits of social media access, this communication method impedes forming deep connections, posing detrimental consequences to enduring romantic relationships among millennials. In recent years, SMU among millennials has skyrocketed, potentially contributing to the increased relational ruptures during this time, such as increased conflict and infidelity rates. With social media providing an outlet for individuals to text, share thoughts, photos, and intimate messages—all with the possibility of evading being caught, the millennial culture is shifting the dynamics of romantic relationships. As a result, therapists are seeing an increased number of couples from the millennial culture with heightened relational dysfunction due to social media and the digital world. Now more than ever, clinicians must be equipped with the necessary skills and competencies to assist millennial romantic relationships impacted by SMU. An in-depth literature review will provide a landscape to examine the role of social media, online dating, partner selection, and issues surrounding infidelity over the last decade. This article will conclude with a case study and recommendations for best practices to help facilitate healing among millennial relationships affected by negative SMU.
Emotional Consequences of Infidelity: Guilt and Regret Experiences Among Perpetrators of Cheating in Heterosexual Dating Relationships
Authors: Varma Parvati , Maheshwari Saurabh
Published: October 2024

Perpetrators of infidelity have to deal with the consequences of their actions, guilt, and regret being a few out of the many. Differences in these outcomes could be based on the kind of infidelity (emotional or sexual) they were involved in and the process of infidelity (spontaneous or planned) they have gone through. To explore the difference, the present study collected data on 196 adults (male = 97, female = 99; Mage = 24.54 years) who had cheated on their romantic partners. Out of the total, 136 participants were involved in self-reported sexual infidelity, and 60 participants were involved in emotional infidelity; 147 participants reported spontaneous infidelity and only 49 participants reported that the process was planned. Results showed that the process of infidelity (spontaneous/planned) significantly affects post-infidelity guilt. However, no role of type of infidelity (emotional/sexual) was found. Furthermore, results showed a significant interaction effect between the type and the process of infidelity on guilt and regret. Sexual-spontaneous infidelity provoked the highest guilt and regret, whereas sexual-planned infidelity led to the slightest guilt and regret. The findings that the emotional consequences of infidelity depend on its nature will help in understanding the aftermaths of infidelity and could apply to helping the perpetrators.
The Geometric Scale of an Urban Space—Neuro-perceptual Limitations for Face-to-Face Driver Behavior
Authors: Tice Patricia C. , Hancock Peter
Published: October 2024

For the last century, the roadway design paradigm has been grounded in the physics of point masses, adjusted for human limitations. However, this is inadequate to assure pedestrian safety in complete streets where vehicle kinematics no longer control. Instead, social and psychological factors manage behavior. Unfortunately, the appropriate design critical psychological principles have yet to be elucidated. We posit that interpersonal perception governs drivers’ behavior, attentiveness and speed in streets. This is bounded by previously delineated human neurological and perceptual propensities. Using these perceptual limitations as postulates in a geometric style proof, we derive the person perception panorama (PPP): a window of interactivity around the moving driver that is continuously monitored for human presence, roughly 60 to 90 feet wide. In this area interpersonal interaction is implicit, functional, and has an impact on driver behavior. Validating evidence, additional governing principles, and an initial speed prediction formula are also included.

Published: October 2024

Currently there is no easy way to rate the ease of evacuation from a building in case of fire or a shooter. Multiple tools, based on agent-based models, exist to simulate building evacuation. However, they have not been compared with human perceptual data of how easy people think it would be to evacuate from a building. This research is part of a project to establish an EASE score (Evacuation with Acceptable Simplicity in Emergencies) and validate that metric with human data. In this study, the authors asked participants to evaluate seven 2D building floor plans for ease of evacuation. There is a gap in the research on perceptions of floor plans which motivated this study’s research questions: (a) Do non-expert users agree on the ease of building evacuation? (b) What factors do viewers use to evaluate ease of evacuation?

Authors: Bustamante Orellana Carlos , Rodriguez Rodriguez Lucero , Huang Lixiao , Cooke Nancy , Kang Yun
Published: October 2024

Trust in automation (TiA) is crucial for human-automation interactions, but traditionally measured statically via discrete survey data points. We developed a mathematical model capturing the dynamic nature of TiA, incorporating measurable components across different timescales, and validated it through experimental data. Our findings show that: (1) trust timescales are important for predicting automation usage, emphasizing trust’s key role in decision-making; (2) short-timescale trust significantly impacts overall trust dynamics, highlighting the importance of recent interactions; (3) trust levels are generally higher in highly reliable automation scenarios, though this pattern emerges after an initial evaluation period; and (4) automation type, implying varying workloads, does not significantly impact trust dynamics in highly reliable systems but fosters increased trust in lower-reliability systems. This study advances our understanding of trust dynamics in automation, contributing to more intuitive and trustworthy technology development.
Downloading Creativity Mods: Improving Our Problem-Solving Skill Transfer

Published: October 2024

Gaming has become ingrained in our modern culture, with many students playing more than 10,000 hours of video games by the time they graduate from high school (McGonigal, 2011). One hundred and 54 participants were randomly assigned to one of three game conditions: perspective-shift game, puzzle game, or video. Our findings suggested that only 30-min of game play that required strategic perspective-shifting significantly increased creativity, however, these results were not driven by participants self-identifying themselves as either gamers or non-gamers. This study directly addresses the gap in evaluating the far transfer of skill sets developed during gameplay to other tasks or contexts.
Synchronization characteristics and stable states of four co-rotating vibrators with balanced slanted elliptical trajectory
Authors: Shuangquan Shi , Yongjun Hou , Pan Fang
Published: October 2024

In the petroleum drilling and mining screening industries, our goal is to enhance excitation force, integrate circular screening with rectilinear transport to obtain the balanced slanted elliptical trajectory (BSET), and reduce screen mesh clogging. This work investigates the synchronization characteristics and stable states of four co-rotating vibrators. The novelty of this work lies in using a novel vibration model to achieve the BSET in the synchronization state and in further considering the influence of a new skewing angle between two eccentric rotors (ERs), which are few in previous vibration screening field. Initially, the vibration model is extracted from the designed prototype. Then, in accordance with Routh–Hurwitz criterion, the synchronization and stability are theoretically analyzed using small parameters of vibrator velocity and phase differences (PDs). The synchronization characteristics related to mechanical structures are discussed via numerical calculation and experimental verification. Results reveal that the synchronization implementation is adversely affected by the skewing angle, even leading to unordered behaviors. Achieving zero-phase or in-phase synchronization with four vibrators is only feasible with a larger symmetric distance and installation angle. This work can contribute a foundation for designing some new types of large vibration screening and material conveyance machines.
State Full Practice Authority Regulations and Nurse Practitioner Practice Autonomy: Evidence From the 2018 National Sample Survey of Registered Nurses
Authors: Slade Eric P. , DePriest Kelli , Commodore-Mensah Yvonne , Samuel Laura , Hanson Ginger C. , D’Aoust Rita
Published: October 2024

State full practice authority (FPA) laws are designed to permit NPs to practice autonomously from physicians. Little is known regarding how FPA laws affect NPs’ practice autonomy in daily practice. This study used nationwide survey data from 20,830 NPs to estimate how NPs’ practice autonomy differs between NPs in FPA and non-FPA states. NPs in states with FPA laws were more than twice as likely as NPs in non-FPA states to practice in clinic settings with no onsite physicians and were twice as likely to not have a physician collaborator. Associations between FPA laws and four other indicators of practice autonomy were positive but smaller in magnitude. States with FPA laws more than 10 years experienced larger changes in nurse practitioner (NP) autonomy compared with states with FPA laws in effect less than 10 years. FPA laws may promote the development of autonomous NP practice sites, thereby expanding access in underserved populations.

Authors: Barbour Bradley N. , Twardowska Karolina , Favero Nicolò , Ghoddousi Payam , Hodkinson Peter
Published: October 2024

Long-duration spaceflights beyond low-Earth orbit, including missions to the Moon and Mars, pose significant health risks. Although biomedical approaches commonly appear in the literature, considering psychological and social factors alongside physiologic health offers a more holistic approach to astronaut care. Integrating the biopsychosocial (BPS) framework into medical planning addresses complex spaceflight challenges and aids in developing mitigation strategies. This review examined health risks associated with long-duration spaceflight within a BPS framework. Sources included governmental space agencies, academic textbooks, and relevant publications from multiple databases. Considering the National Aeronautics and Space Administration's Human Research Program's 5 main hazards, a conceptual model was developed to highlight the multifactorial BPS effects of spaceflight. In space, astronauts face unique environments and biological adaptations, including fluid shift, plasma volume loss, bone density loss, and muscle atrophy. Noise and the absence of natural light disrupt circadian rhythms, causing sleep disturbances and fatigue, which affect physical and mental health. Studies on crews in isolated and confined extreme environments reveal psychosocial challenges, including impaired mood and cognition, interpersonal tension, and miscommunication. International collaboration in spaceflight introduces differences in communication, problem solving, and social customs due to diverse cultural backgrounds. Upcoming long-distance missions likely will amplify these challenges. This review emphasizes BPS health considerations in long-duration spaceflight. It highlights the interplay among psychological, social, and biological factors, advocating for multidisciplinary teams and a holistic approach to astronaut health and mission planning and the potential added value of BPS perspectives in considering countermeasures.
Dietary Flavonoid Intake and Risk of Mild Cognitive Impairment in the Elderly: A Case-Control Study
Authors: Liu Quanri , Zhang Rui , Chen Yujiao , Lu Yanhui , Cui Fangqiang , Zhang Qiang , Zhang Chunmei
Published: October 2024

Background:

This study investigates the association between dietary flavonoid intake and the incidence of mild cognitive impairment (MCI) through a matched case-control design.

Methods:

Dietary intake was assessed using a food frequency questionnaire, comparing the intake of flavonoids between individuals with MCI and those with normal cognitive function. Logistic regression analysis was employed to evaluate the correlation between dietary flavonoid intake and the risk of MCI. Additionally, blood concentrations of S100β, a marker of the blood-brain barrier (BBB) integrity, were measured using electrochemiluminescence immunoassay, and Pearson correlation analysis was conducted to explore the relationship between dietary flavonoid intake and blood S100β levels.

Results:

Compared to participants with normal cognition, those with MCI had significantly lower dietary intakes of total flavonoids, isoflavones, daidzein, glycitein, genistein, kaempferol, myricetin, flavonols, and anthocyanidins, while the intake of peonidin was significantly higher. Univariate logistic regression analysis indicated that high dietary intake of total flavonoids, isoflavones, daidzein, glycitein, genistein, kaempferol, myricetin, and flavonols was negatively correlated with MCI, whereas peonidin intake was positively correlated with MCI. Multivariate logistic regression analysis confirmed these findings. Pearson correlation analysis revealed a significant negative correlation between dietary intake of kaempferol and myricetin and blood S100β levels.

Conclusion:

Increasing the dietary intake of total flavonoids, isoflavones, daidzein, glycitein, genistein, and flavonols appears to be a protective factor against MCI, while higher intake of peonidin is associated with an increased risk of MCI. The protective or adverse effects of these flavonoids may not be related to the permeability of the BBB. Myricetin and kaempferol intake may protect cognitive function by maintaining BBB integrity.
Rethinking the Terminology: A Perspective on Renaming Polycystic Ovary Syndrome for an Enhanced Pathophysiological Understanding
Authors: Taieb Ach , Asma Gorchane , Jabeur Methnani , Fatma Ben Abdessalem , Nassim Ben Haj Slama , Asma Ben Abdelkrim
Published: October 2024

Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder that affects women at various stages of life, presenting a wide range of symptoms and health implications. The term “Polycystic Ovary Syndrome” can be misleading, prompting many within the medical community and advocacy groups to advocate for a name change. Critics argue that this terminology can complicate understanding and awareness of the disease among patients. The primary concern is that PCOS emphasizes the ovarian aspect, fostering the misconception that PCOS is merely a gynecological disorder. In reality, PCOS impacts multiple organ systems, particularly metabolic health. Patients frequently experience insulin resistance, weight gain, irregular menstrual cycles, and hirsutism—symptoms that extend beyond ovarian dysfunction. In light of these issues, there is increasing support for renaming PCOS to better reflect its systemic implications and minimize confusion. The current name may hinder understanding and potentially lead to inadequate disease management. Alternative names have been proposed, including “Ovarian Dysmetabolic Syndrome,” which our team supports, as well as “Metabolic Reproductive Syndrome” and “Hyperandrogenic Persistent Ovulatory Dysfunction Syndrome.” These alternatives aim to highlight the hormonal imbalances and metabolic disturbances associated with the condition, fostering inclusivity and reducing stigma for all affected individuals. This narrative review provides a historical overview of PCOS, tracing its recognition from early descriptions to contemporary guidelines. We discuss the evolving understanding of its pathophysiology and the rationale behind the proposed name change. By adopting a new nomenclature, we can enhance understanding among healthcare professionals, increase inclusivity for affected women, reduce the stigma and anxiety linked to the diagnosis, and offer a more accurate representation of the condition’s complex pathophysiology.
Dynamic analysis of a high-speed micro compressor supported by spiral-grooved hydrodynamic air bearing
Authors: Ren Tianming , Feng Ming , Zhang Jianhua
Published: October 2024

Spiral-grooved hydrodynamic air bearings are used in high-speed machines due to their advantages of oil-free, low friction, and compact structure. This paper aims to investigate the dynamic characteristics of a high-speed rotor supported by spiral-grooved hydrodynamic air bearings and the effects of spiral groove parameters. A mathematical model of the rotor-bearing system is developed by coupling the rotor nonlinear motion equations and the bearing dynamic Reynolds equation. The finite element method combined with the Runge-Kutta method is employed simultaneously to obtain the nonlinear trajectory of the rotor-bearing system. The theoretical model is verified by experiments on the built micro compressor prototype. The numerical predicted onset speed of the sub-synchronous motion of the rotor-bearing system agrees well with the experimental observations. Furthermore, the effects of radius clearance, groove depth, groove angle, groove axial and circumferential width on the dynamic performance of the rotor-bearing system are analyzed. The results show that radius clearance has the most significant influence, followed by groove depth, groove axial, and then circumferential width. The groove angle has the least impact.

Authors: Li Mengyu , Suk Jiyoun , Zhang Yini , Pevehouse Jon C. , Sun Yibing , Kwon Hyerin , Lian Ruixue , Wang Rui , Dong Xinxia , Shah Dhavan V.
Published: October 2024

This study proposes affordances for discursive opportunities (ADO) as a theoretical framework that leverages the concept of technological affordances and the theory of discursive opportunities to understand platform potential in shaping social media activism. Specifically, ADO underscores how social media platform affordances (e.g., algorithmic curation, shared group identity and culture, connectivity) shape movement visibility, resonance, and legitimacy, all of which can mobilize activism efforts. We further situate our discussion in the cross-platform context to explore both differences and interconnections between different platforms in facilitating digital activism. By analyzing 20,363,128 English posts related to the #MeToo movement from 2017 to 2020 on Twitter, Facebook, and Reddit using supervised machine learning and time series analysis, we reveal platform variations in affording discursive opportunities for visibility, resonance, and legitimacy, which shape activism efforts differently across platforms. We also find a unidirectional relationship from activism on Twitter and Reddit to activism on Facebook.
Lost in translation: Barbie and subtitle discrepancies in China
Authors: Gu Fangqing
Published: October 2024

I examine the subtle yet impactful subtitle translation errors in the Chinese version of Barbie (2023). These translation missteps undermine the film's feminist narratives and representations of gender, which reveals the translations’ capacity to distort the original English screenplay. Employing an interdisciplinary approach that integrates film studies, feminist theory and translation studies, I emphasise the instrumental role of subtitles as not just linguistic tools but narrative constructs that significantly influence the shaping and affirmation of gender identities. The analysis illuminates the pivotal role of subtitles in reflecting and shaping societal norms, offering insights for developing more culturally sensitive and empowered translation methodologies in the realm of international cinema.
Spray characteristics and combustion mechanism influence on combustion stability of UDMH/NTO pre-combustor under external excitation
Authors: Jin Ping , Yang Danqi , Gao Yushan , Yang Yongzhao , Cai Guobiao
Published: October 2024

To study the combustion stability of liquid rocket engines with hypergolic propellant more comprehensively, external pressure pulse excitation was applied to the UDMH (unsymmetrical dimethylhydrazine)/NTO (methylhydrazine) pre-combustor. The effects of pressure pulse intensity, spray characteristics (droplet diameter and spray cone angle), and combustion mechanism on combustion stability characteristic frequencies and attenuation characteristics after excitation were investigated. The simulation results show that all operation conditions capture the first three longitudinal frequencies of the pre-combustor, and all factors have a greater impact on frequencies with higher orders. Increasing the pulse intensity and reducing the droplet diameter are not conducive to combustion stability. The influence of the spray cone angle on the combustion stability is not monotonous. The pre-combustor has good stability when the spray cone angle is 70°. Different combustion mechanisms have a significant effect on the results before and after pressure pulses, and considering a more complete combustion process may increase the attenuation time in the pre-combustor. The obtained rules can provide a reference for the design and simulation of hypergolic liquid rocket engines, which is beneficial for predicting and evaluating the combustion stability of liquid rocket engines.
Fabrication and mechanical evaluation of lattice structures for developing a lumbar support brace
Authors: Park Seiyoung , Kim Dong-Eun
Published: October 2024

This study aims to explore and select a sample of three-dimensional (3D) printed lattice structures suitable for fabrication of a lumbar brace. In particular, the study compared honeycomb, gyroid, and X-shape lattice structures. Thirty-six samples with two thicknesses, two pattern repeats, three lattice structures, and three 3D printing manufacturing methods and material variables were fabricated to evaluate tensile strength, flexural strength, weight, and density. Mechanical evaluation revealed that the tensile and flexural strengths of the honeycomb structure were higher than those of other structures. In addition, the fused deposition modeling (FDM) method using thermoplastic polyurethane (TPU) material had higher tensile and flexural strengths compared with the other two printing methods and materials. The honeycomb structure weighed the most, followed by the X-shape and gyroid structures. The sample made of PolyJet method with Agilus material showed higher values of weight and density than the other samples. Based on the experimental results, it is considered that TPU material, FDM, and selective laser sintering printing methods are suitable for production of the lumbar support brace because it is flexible and allows body movement but has moderate strength and density. By adjusting the pattern repeat and thickness of the lattice structure variable, we can determine the structure that is most suitable for lumbar support. Considering the lightweight requirements of lumbar support, future studies should devise ways to improve the lightweight properties of samples.

Published: October 2024

Purpose

To assess whether gray-scale ultrasound (US) based radiomic features can help distinguish HER2 expressions (ie, HER2-overexpressing, HER2-low-expressing, and HER2-zero-expressing) in breast cancer.

Materials and Methods

This retrospective study encompassed female breast cancer patients who underwent US examinations at two distinct centers from February 2021 to July 2023. Tumor segmentation and radiomic feature extraction were performed on grayscale US images. Decision Tree analysis was employed to simultaneously evaluate feature importance, and the Least Absolute Shrinkage and Selection Operator technique was utilized for feature selection to construct the radiomic signature. The Area Under the Curve (AUC) of the Receiver Operating Characteristic curve was employed to assess the performance of the radiomic features. Multivariate logistic regression was used to identify independent predictors for distinguishing HER2 expression in the dataset.

Results

The training set comprised 292 patients from Center 1 (median, 51 years; interquartile range [IQR]: 45-61), while the external validation set included 131 patients from Center 2 (median, 51 years; IQR: 45-62). In the external validation dataset, the radiomic features achieved AUC of 0.76 for distinguishing between HER2-low and positive tumors versus HER2-zero tumors. The AUC for differentiating HER2-low (1+) from HER2-zero tumors was 0.74, and for distinguishing HER2-low (2+) from HER2-zero tumors, the AUC was 0.77. In the multivariate analysis assessing HER2-low and HER2-positive versus HER2-zero tumors, internal echoes (P = .029) and margins (P < .001) emerged as independent predictive factors.

Conclusion

The radiomic signature and tumor descriptors from gray-scale US may predict distinct HER2 expressions of breast cancers with therapeutic implications.

Authors: Chen Xuemei , Wang Wei , Huang Xiaotong , Diao Wenchao , Xu Chendi , Jia Lecheng , Li Hua , Li Bin , Jiang Xiaobo
Published: October 2024

Objective

This study assesses the physical properties of the silicone rubber (SR) bolus, compares its dosimetric characterization with those of gel and thermoset boluses, aiming to evaluate the feasibility and stability of utilizing SR bolus for head photon-beam radiotherapy.

Methods

Three types of boluses (gel, thermoset, and SR) were prepared with same dimensions. Firstly, the physical properties of SR bolus (density, tensile strength and hardness) were assessed pre-irradiation and post-irradiation. Secondly, the percentage of depth dose (PDD) curve was calculated using the treatment planning system (TPS) and measured with a plane-parallel. Thirdly, these three boluses were individually placed on the head phantom, followed by computed tomography (CT) scans to delineate the customized target area and organs at risk (OARs) for treatment planning. Over the subsequent three weeks, fan-beam CT (FBCT) images were obtained weekly and registered with the initial CT to modify the target area and OARs. Fourthly, the adhesion differences, dose distributions, and inter-fraction reproducibility of the three boluses were compared and evaluated.

Results

The results observed that post-irradiated SR bolus exhibited higher hardness values ( p < .01) than the pre-irradiated one, with no significant differences in tensile strength and density. The PDD curves of all three boluses showed similarity within a difference range less than ±1%. The air gaps between the SR, thermoset, and gel boluses and skin surfaces were measured as 0.07 cm3, 2.96 cm3, and 4.82 cm3, respectively. Compared with gel bolus and thermoset bolus, the SR bolus demonstrated noticeable inter-fraction reproducibility.

Conclusion

The SR bolus can be fabricated at room temperature, adheres to irregular body surfaces, and retains its physical properties post-irradiation. Additionally, this bolus has comparable dosimetric characterization to other commercial boluses, and may provide notable protection for OARs. Therefore, the SR bolus is recommended as a feasible and stable material for head photon-beam radiotherapy.
Quality Assessment of YouTube Videos on Complementary and Alternative Medicine (CAM) for Cancer Using a Newly Developed Tool
Authors: Huchel Sophia , Grumt Alina , Keinki Christian , Buentzel Judith , Käsmann Lukas , Huebner Jutta
Published: October 2024

Background:

The global burden of cancer continues to rise and complementary and alternative medicine (CAM) is attracting a lot of interest. However, quality of online information on CAM, particularly on platforms like YouTube, remains questionable. This study aimed to create a comprehensive assessment tool to assess the quality of CAM-related YouTube videos, crucial for informed decision-making in oncology.

Methods:

The assessment tool was developed by adapting existing criteria for website content analysis to video rating. A YouTube search was conducted using German-language terms related to CAM (“complementary medicine (CM) for cancer” and “alternative medicine (AM) for cancer”). In total 25 videos were assessed based on the defined criteria and assigned to five different types of providers (journalism, healthcare organization, hospital or health insurance, independent person, non-medical organization). Statistical analysis was conducted using IBM SPSS Statistics 27.

Results:

Interrater reliability analysis showed an Intraclass Correlation Coefficient (ICC) of .91, indicating good to excellent agreement. The average video result was of poor quality, with none of the videos meeting all criteria. The videos achieved a mean rating of 38.2 points (SD: 6.5 points; possible range: 20-60 points). Journalism-based videos showed the most views per days, particularly surpassing those from hospitals or health insurance providers (Kruskal-Wallis-Test: z = 3.14, P = .02). However, there was no statistically significant correlation between video quality and the type of provider or interaction indices. Videos retrieved under the search term “CM” generally scored higher in quality than those under “AM” (Mann-Whitney U test: U = 39.5, P = .04). Nonetheless, "CM" videos were less frequently viewed (Mann-Whitney U test: U = 31.0, P = .01).

Conclusion:

This study, the first of its kind focusing on CAM in cancer care emphasized the challenges in identifying credible sources on social media platforms such as YouTube. The developed assessment tool offers a more detailed evaluation method for health-related videos but requires further refinement and testing. Collaboration between healthcare and media entities is suggested to improve the dissemination of reliable information on platforms like YouTube.

Trends in Upper Extremity Saw Injuries From 2003 to 2022
Authors: Monir Joseph G. , Nguyen Jenny , McQuillan Thomas J. , Wagner Eric R.
Published: October 2024

Purpose:

Saws are a common source of upper extremity injury. There have been several commercial and government-mandated safety mechanisms designed to reduce the number of saw injuries. We aim to assess the trends in the incidence and impact of saw-related upper extremity injuries over the last 2 decades.

Methods:

The National Electronic Injury Surveillance System database was queried from January 2003 to December 2022 for upper extremity injuries caused by saws. Summary statistics for primary body part injured and diagnosis were calculated. Linear regression was performed to evaluate trends in the number of injuries over time.

Results:

An estimated 1.38 million injuries (weighted) presenting to emergency departments were reported from January 2003 to December 2022. Patients had a mean age of 50.5 ± 18.1. Digits (82.2%) accounted for most injuries, followed by hands (11.9%). The lower arm (3.4%), wrist (1.66%), shoulder (0.3%), elbow (0.2%), and upper arm (0.2%) accounted for fewer injuries. There was a downtrend in number of saw injuries over the study period (R = 0.83, R2 = 0.69, p < .001). Subgroup analysis showed decreases in number of injuries to fingers (R = −0.82, R2 = 0.67, p < .001) and wrists (R = −0.61, R2 = 0.37, p = .004). The most common diagnoses were lacerations (69.7%), fractures (12.6%), and amputations (9.9%).

Conclusions:

Upper extremity saw injuries have significantly decreased over the last 20 years. The fingers and hands account for the vast majority of saw injuries, resulting most commonly in lacerations, fractures, and amputations.

Seamless shifting and suppressing clutch judder of 2-speed DCT for EV by deep reinforcement learning
Authors: Ogawa Kazuki , Aihara Tatsuhito , Minorikawa Gaku
Published: October 2024

One of the challenges facing widespread adoption of electric vehicles (EVs) is their short driving range. To address this challenge, the development of various EV transmissions is underway. In transmissions, clutches are used for disconnection from the drive source, and a phenomenon called judder, which is a violent vibration, may occur when the clutch slides on a frictional surface. To resolve this problem, the use of deep reinforcement learning, which is being used and advanced in areas such as machine control in simulations, was focused upon. The purpose of this study is to suppress clutch judder using deep reinforcement learning. The deep reinforcement learning model was developed for seamless gear shift control, and the gearshift results without control were compared with the gearshift results after training. As a result, a control rule that achieves seamless gear shifting while suppressing the judder is designed by applying deep reinforcement learning to gear shifting control. In addition, seamless gear shifting can be achieved for various patterns of friction coefficients, enabling the development of a robust controller for changing the friction coefficients.
Intervention accuracy and perception of fatigue in state-level Australian football umpires
Authors: Wilson Corey , Scanlan Mark , Bradbury Duncan G. , Barley Oliver R.
Published: October 2024

This investigation examined intervention accuracy and perception of fatigue associated with umpiring state-level Australian Rules football (AF). 39 field umpires (Age: 25.2 ± 6.8 y, Body Mass: 74.6 ± 7.9 kg, Height: 178.9 ± 7.4 cm) employed by the Western Australian Football Commission, were recruited. Intervention accuracy (whether given free kicks were correct) was analysed post-event by the lead investigator using footage of the matches, with two umpire coaches being used for reliability. Perception of fatigue was assessed pre- and post-match using a questionnaire. Data was collected in 22 Western Australian Football League matches in the 2023 season. 384 free kicks were recorded, with 343 correct and 41 incorrect decisions. Each umpire awarded 9.8 ± 3.8 free-kicks, with a distribution of correct-to-incorrect being 8.8 ± 3.2 to 1.1 ± 1.1 free-kicks per match. Intervention accuracy was 89.3 ± 10.4% correct. Significant decline in intervention accuracy between first and second half (W = .931, p = .021) was found. No significant declines in intervention accuracy between quarters were observed. Perception of fatigue was unchanged across matches ( p = .074). Our results demonstrate that umpires are generally accurate when adjudicating free kicks but said accuracy declines across a match. The results of this study, provide important insight on free-kick accuracy and perception of fatigue in state-level AF umpires, and may help regulatory bodies designing strategies to improve umpiring outcomes.
A qualitative analysis of existing concussion return to play protocols and psychological recovery management in Gaelic games
Authors: Daly Ed , Ryan Lisa
Published: October 2024

Background

Sports related concussions are a common injury in field-based contact sports including Gaelic games. Even though accurate data on concussion in Gaelic games is currently limited, it is well documented that concussion is a common injury in Gaelic sports. The purpose of this current research was to discern the psychological impact of concussion on Gaelic games athletes as in many instances, recovery from concussion focuses mainly on physical recovery.

Methods

A grounded theory methodology was used to explore the experiences of a cohort of adult male and female amateur and elite amateur Gaelic games athletes (n = 22) and their experiences involving psychological recovery post-concussion and eventual return to play. The data for this study were gathered through a series of individual semi-structured interviews.

Results

Two major themes were identified, (1) lack of psychological recovery management for concussion in Gaelic games athletes and, (2) non-standardised concussion protocols and concussion education within Gaelic games. These themes were further divided into categories and subcategories.

Conclusion

Recovery from concussion in Gaelic games is broadly a non-standardised process, whereby recovery processes are haphazard and lack enforcement.

Objectives: This study aimed to investigate the potential of Dendrobium officinale Kimura & Migo (DOKM) in ameliorating high cholesterol-induced atherosclerosis (AS) in zebrafish, focusing on the development of safe and effective drugs with low toxicity for AS treatment. Methods: A zebrafish AS model was established by feeding zebrafish a high cholesterol diet (HCD). Treatment was administered using 1 mg/L and 10 mg/L DOKM water extract. Fluorescence microscopy was utilised to observe the effects of DOKM on HCD-induced cholesterol accumulation, neutrophil accumulation, and macrophage infiltration in the vasculature. The impact of DOKM on HCD-induced disorders of lipid metabolism was assessed using Nile red staining. Total cholesterol (TC), triglycerides (TG), and low-density lipoprotein (LDL-C) levels in zebrafish were measured using kits. The expression of pcsk9, srebf2, and hmgcr genes in zebrafish was determined using RT-PCR. HE staining and Elvitegravir (EVG) staining were employed to assess the effect of DOKM on plaque formation in the blood vessels of AS zebrafish. Results: A total of 145 compounds were collected from Dendrobium officinale, along with 680 corresponding targets. Additionally, 1583 atherosclerosis-related targets were identified, with 202 representing interaction targets between Dendrobium officinale and atherosclerosis-related targets. Key compounds identified included Gigantol, Chrysotobibenzyl, Naringenin Chalcone, Hesperetin, and Tangeretin. The core targets of Dendrobium officinale for atherosclerosis treatment were STAT3, PTPN11, JAK2, epidermal growth factor receptor (EGFR), platelet-derived growth factor receptor alpha (PDGFRA), proto-oncogene tyrosine-protein kinase Src (SRC), STAT1, TP53, ESR1, and AKT1. GO functional enrichment analysis revealed a total of 2090 GO biological functional entries. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed 200 AS signalling pathways associated with DOKM treatment for atherosclerosis. DOKM significantly attenuated cholesterol accumulation, neutrophil aggregation, and macrophage infiltration in the blood vessels of AS zebrafish, ultimately leading to reduced plaque formation. AS zebrafish exhibited lipid metabolism disorders, characterised by significant increases in TC, TG, and LDL-C levels, as well as mRNA expression of pcsk9, srebf2, and hmgcr genes. Treatment with DOKM significantly improved these lipid metabolism disorders. Conclusion: DOKM effectively attenuates HCD-induced AS, and this therapeutic effect on AS may be related to its role in improving lipid metabolism dysfunction.

Background and Purpose

Neurohospitalists specialize in the care of hospitalized patients with neurological conditions. As the neurohospitalist model of patient care has grown rapidly and in diverse ways, there has been increasing demand for a formal definition of the field, particularly to support curriculum development for learners at multiple levels.

Methods

The Neurohospitalist Society (NHS) formed a Core Competencies Committee in 2021. This committee defined the scope of the Neurohospitalist Core Competencies and organized the competency topics into chapters. This chapter list was approved by the members of the NHS. An open invitation was made to the general membership of the NHS to write chapters on a first-come, first-served basis, using a standardized chapter template developed by the Committee. A three-step editing process was completed, with members of the Committee serving as editors. A dissemination strategy was designed, including drafting of 2 manuscripts (the Core Competencies themselves, and this accompanying manuscript) and outreach to the general membership of the NHS.

Results

The Neurohospitalist Core Competencies include 27 chapters divided into 3 sections: neurological conditions; clinical interventions and interpretations of ancillary studies; and neurohospitalist role in the health care system. The complete version of the Neurohospitalist Core Competencies is published as a separate manuscript in this issue of The Neurohospitalist.

Conclusions

The creation of the Neurohospitalist Core Competencies was a multi-year initiative intended to support practicing neurohospitalists, trainees interested in pursuing careers in the field, medical education leaders, and administrative leaders of hospitals and departments.

Objective

The purpose of this study was to evaluate outcomes following autologous osteochondral transplantation (AOT) for the treatment of osteochondral lesions of the talus (OLT) at a minimum of 10-year follow-up.

Design

Retrospective chart review identified patients who underwent AOT for the treatment of OLT. Pre-operative magnetic resonance imaging (MRI) scans were obtained in all patients. Clinical outcomes assessed included: pre- and post-operative foot and ankle outcome score (FAOS), visual analog scale (VAS), patient satisfaction, complications, failures and secondary surgical procedures.

Results

Thirty-nine patients with a mean lesion size was 122.3 ± 64.1 mm2 and mean follow-up time of 138.9 ± 16.9 months were included. The mean FAOS scores improved from a preoperative score of 51.9 ± 16.0 to 75.3 ± 21.9 ( P < 0.001). Increasing lesion size was variable associated with inferior FAOS scores (R2 = 0.2228). There was statistically significant higher mean T2 relaxation values at the superficial layer at the site of the AOT graft (42.9 ± 5.2 ms) compared to the superficial layer of the adjacent native cartilage (35.8 ± 3.8 ms) ( P < 0.001). Seventeen complications (43.6%) were observed, the most common of which was anterior ankle impingement (25.6%). There were 2 failures (5.1%), both of which had a history of prior bone marrow stimulation via microfracture and post-operative cysts identified on MRI.

Conclusion

This retrospective review found that AOT for the treatment of large OLTs produced a 94.9% survival rate at a minimum of 10-year follow-up. Increasing lesion size was associated with inferior clinical outcomes. The findings of this study indicates that AOT is a viable long-term surgical strategy for the treatment of large OLTs.
Magnetic resonance venography study of venous structures of the transverse-sigmoid sinus region in the Han Chinese population: A cross-sectional study
Authors: Zhou Zibo , Yu Jinlu
Published: October 2024

Objective:

Venous structures of the transverse-sigmoid sinus region have been insufficiently studied by magnetic resonance venography, especially in the healthy Han Chinese population.

Methods:

Magnetic resonance venography data were reconstructed. The relevant parameters were recorded. A paired t-test was used to compare the diameters of the inferior petrous sinus at the origin and termination. An unpaired t-test, a chi-squared test or Fisher’s exact test was used to compare other data.

Results:

One hundred healthy participants were included. The average age was 36.6 ± 17.1 years, and the ratio of males to females was 1:1. The development of the transverse-sigmoid sinus had a right-sided predominance in 51% of patients. Statistical analysis revealed significant differences ( p < 0.05) in the lengths of bilateral TSs, the lengths of bilateral partial TSs from the torcular to lateral tentorial sinus, the diameters between bilateral TSs at the origin and the lateral tentorial sinus, the diameters between bilateral TS-sigmoid sinus junctions and sigmoid sinus terminations, and the inferior petrous sinus diameters at the origin and termination. Statistical analysis revealed that the right lateral tentorial sinus was more likely to originate from the TS ( p < 0.05). Statistical analysis revealed no significant differences ( p < 0.05) between transverse-sigmoid sinus development and inferior petrous sinus continuity or between transverse-sigmoid sinus development and inferior petrous sinus continuity and bilateral inferior petrous sinus continuity.

Conclusions:

This study revealed that the right transverse-sigmoid sinus was predominantly larger in diameter, the torcular Herophili tended to deviate to the right, and the right lateral tentorial sinus tended to drain into the TS. The inferior petrous sinus at the origin was thicker than that at the termination, and the right inferior petrous sinus was thicker than the left inferior petrous sinus. transverse-sigmoid sinus development had no effect on inferior petrous sinus continuity, and there was no difference in inferior petrous sinus continuity between the left and right sides.
