Mechanisms of Injury for Traumatic Brain Injury Among U.S. Military Service Members Before and During the COVID-19 Pandemic.

To understand the mechanisms of injury and demographic risk factors associated with traumatic brain injury (TBI) patients among active and reserve service members in the U.S. Military before and during the COVID-10 pandemic. Active and reserve service members diagnosed with an incident TBI from January 2019 through September 2021 were selected. Traumatic brain injury patients diagnosed before March 1, 2020 were categorized as pre-COVID (PC), and patients diagnosed on or after March 1, 2020 were categorized as the intra-COVID (IC) group, aligning closely with the date when the World Health Organization officially proclaimed the pandemic. We determined the frequency of causes of injuries associated with TBI separate by sex, age, occupation, and TBI severity. In addition, we conducted multivariate logistic regression analyses to assess the demographic risk factors associated with TBI severity during the PC and IC eras. Our cohort included 48,562 TBI patients: 22,819 (47.0%) diagnosed during the PC era and 25,743 (53.0%) diagnosed during the IC era. The major mechanisms of injury within our TBI cohort were being struck by/against objects, falls/slips/trips, and motor vehicle traffic accidents before and during the pandemic. The most common causes of TBI were not impacted by COVID, but motor vehicle accidents did increase during the IC era. The mechanisms of injury associated with TBI differed by TBI severity: being struck by or against an object caused more mild and moderate TBI; motor vehicle accidents caused more severe TBI; and firearms was a major cause of penetrating TBI. In addition, the percentage of severe TBI because of firearms rose sharply during the IC era. Further, women were more likely to be diagnosed with mild TBI compared to men. Military leaders should consider how different causes of injury are associated with differing TBI severities and how certain demographic groups were vulnerable to specific TBI severities when developing injury prevention programs.

Drowsy driving prevalence and beliefs among a nationally representative US sample: A report from the National Sleep Foundation

ObjectivesDrowsy driving is a preventable form of impaired driving, represents a large public health concern, and accounts for a significant proportion of motor vehicle crashes, injuries, and deaths. There is a limited body of research documenting the prevalence and frequency of drowsy driving, alongside the public’s perceptions and attitudes surrounding drowsy driving. The overarching goal of the present study was to document the prevalence, frequency, perceptions, attitudes, and associated sleep behaviors and beliefs related to drowsy driving. MethodsThe National Sleep Foundation conducted a national online survey of 1012 adults via the probability-based Ipsos Public Affairs KnowledgePanel. The survey was conducted in either English or Spanish, depending on participant preferred language. Respondents answered questions about the occurrence of drowsy driving, attitudes and beliefs about drowsy driving, and habitual sleep duration. ResultsResults indicated that the majority of US adults (95%) perceived drowsy driving as a risk; however, the lifetime prevalence of drowsy driving was high—62% of all drivers reported driving while so tired that they had a hard time keeping their eyes open. Individuals who obtained the NSF recommended sleep duration drove while drowsy less frequently. ConclusionsDrowsy driving is a preventable and common behavior at the intersection of sleep health and public safety. Drivers who get adequate nighttime sleep are less likely to drive while they are so tired that they have a hard time keeping their eyes open. Public health campaigns encouraging adequate sleep to drive alert are needed.

Mindfulness, crashes, and risky driving behaviors among adolescents and young adults in the United States

PurposeThe purpose of this study was to examine the association between individual-level mindfulness and a range of risky driving behaviors among U.S. adolescents. MethodsWe conducted a survey of a nationally representative sample of 16–19-year-olds, recruited from the National Opinion Research Center AmeriSpeak panel, a probability-based sample. Participants completed the Mindful Attention Awareness Scale. Risky driving measures were adapted from the Youth Risk Behavior Survey. Spline regression analysis was performed to identify the threshold where mindfulness scores significantly changed driving behaviors. ResultsAfter adjusting for age, gender, and race, adolescents reporting higher mindfulness scores were significantly less likely to engage on all risky driving behaviors and significantly less likely to have been involved in a crash. Spline regression analysis indicated that a mindfulness score of 75 corresponded to the minimum marginal probability change averaged across the outcomes of interest. DiscussionThis paper describes a previously unknown association between mindfulness and risky driving in a vulnerable population which is at higher risk of injury and death from motor vehicle crashes. The strength of the associations across a range of behaviors suggests mindfulness could be a general protective factor for adolescents’ driving behaviors and suggests that mindfulness training may be a promising safety intervention for adolescents. A mindfulness score of 75 could be a potential target for mindfulness training interventions aiming to reduce risky driving behaviors and crashes among teenage drivers.Abbreviations: ADHD, Attention Deficit Hyperactivity Disorder; CI, Confidence Interval; MAAS, Mindful Attention Awareness Scale; NORC, University of Chicago’s National Opinion Research Center; YRBS, Youth Risk Behavior Survey.

Simultaneous clavicular hook plate fixation in bilateral distal clavicle fractures (Neer type II): A case report.

Bilateral distal clavicle fractures (BDCF) are exceedingly rare types of fractures. This study aimed to evaluate the surgical treatment under a single anesthesia for trauma-induced BDCF (Neer type II) through a case report. The patient brought to the emergency department due to a motor vehicle accident exhibited severe pain, tenderness, swelling, and deformity in both shoulder regions upon physical examination. No significant pain or tenderness was detected in other areas of the body. There were also no signs of additional neurological deficits or vascular pathology in the extremities. Radiographic examinations led to a diagnosis of BDCF (Neer type II). Surgical intervention involved the simultaneous application of a neutral-angled hook plate to both clavicles via open reduction. Postoperative radiographs taken at the 12th week demonstrated complete healing in both fractures and no functional limitations in shoulder movements. BDCF can compromise the stability of the shoulder girdle, necessitating surgical intervention with anatomical reduction and rigid fixation.

Gradient variations of formation mechanisms and sources of PM1 at the steep slope from western SiChuan Basin to eastern Tibetan Plateau

Vertical distributions of chemical components of particulate matter (PM) are essential for better understanding the climate, environmental and health effects. The steep slope from western SiChuan Basin (SCB) to eastern Tibetan Plateau (TP) provides a good platform for obtaining the gradient variations of PM chemical components. Daytime and nighttime PM1 (particulate matter smaller than 1 μm) samples were collected with the medium-volume sampler at six sites with elevation ranging from 500 m to 3500 m (Chengdu, Sanbacun, Wenchuan, Lixian, Maerkang and Hongyuan). The secondary inorganic ions and carbonaceous aerosols were the largest contributor to PM1 concentrations. The chemical components from the anthropogenic sources existed strong stratification with high concentrations inside the basin, while primary natural ions showed little discrepancy among the sites. The concentrations of primary inorganic ions from anthropogenic sources were much higher at nighttime than daytime, which was contrary to the diurnal cycle of secondary inorganic ions. Spatial heterogeneity of PM chemical components was large between basin and plateau sites, especially for NO3− and NH4+, large depending on season and daylight. The excess NH4+ concentrations existed in spring, summer and fall, while SO42− and NO3− cannot be completely neutralized by NH4+ in winter. The proportion of secondary formation in all sources significantly increased from about 10 % to 30 %–40 % with the increased elevation, while the contribution of motor vehicles declined from western SCB to eastern TP. This study will fill the scarce observations of PM chemical components at the sloped terrain and deepen the understanding of formation mechanism of heavy pollution inside the basin.

The Influence of "Labels" for Neck Pain on Recovery Expectations Following a Motor Vehicle Crash: An Online-Randomized Vignette-Based Experiment.

OBJECTIVES: To (1) investigate whether different labels for neck pain after a motor vehicle crash (MVC) influenced recovery expectations and management beliefs, (2) explore reasons for low recovery expectations and greater likelihood for lodging a claim, and (3) explore the moderating effect of neck pain history and sociodemographic characteristics. DESIGN: Online randomized experiment with nested qualitative content analysis. METHODS: We randomized 2229 participants from the general population (mean age: 46.7 ± 17.5 years; 72.4% females; 66% with previous or current neck pain; 10% with an MVC experience) to read 1 of 5 scenarios describing a patient with neck pain after an MVC, each was labeled as whiplash injury, whiplash-associated disorder, posttraumatic neck pain, neck pain, or neck strain. The primary outcome was recovery expectations, rated on a 0- to 10-point scale. RESULTS: Participants allocated to whiplash-associated disorder or neck pain had lower recovery expectations than those allocated to neck strain (adjusted mean difference [95% confidence interval]: -0.5 [-0.9 to -0.1] for both comparisons). Whiplash-associated disorder led to more recovery uncertainty, while neck pain led to greater doubt about the health care provider. Most secondary outcomes showed significant but small differences. Participants allocated to neck strain were less inclined to claim than those allocated to whiplash-associated disorder or whiplash injury due to less perceived need for financial support. Neck pain history moderated labeling effects on recovery expectations; household income moderated the claim intention. CONCLUSIONS: Labels for neck pain after an MVC influenced recovery expectations and management preferences. The clinical relevance of the small effects was unclear.

Vocs pollution and respiratory exposure in commercial and residential underground parking garages

The indoor air quality in Underground Parking Garages (UPGs) has deteriorated significantly, primarily due to the high concentrations of particulate matter and volatile organic compounds (VOCs) emitted by idling or low-speed motor vehicles. However, the compositional characteristics and respiratory exposure to VOCs in UPGs have not been quantitatively analyzed. To establish a method for investigating the respiratory exposure to VOCs among different populations in UPGs, a three-dimensional dynamic diffusion model of indoor pollutants was developed based on monitoring data from 116 components in various UPGs in a large city in northern China. The results indicated that air pollution in underground spaces poses significant health risks to workers and children. Furthermore, a comprehensive approach is essential for improving ventilation capacity and air quality in underground transportation spaces.

Effects of periodic long-wave deviations on the dynamic behaviors of spur gear systems

Noise reduction plays a major role in the drive train of motor vehicles operating at higher speeds. Long-wave deviations of gear systems related to manufacturing and assembly errors, such as tooth pitch deviation and geometric eccentricity, exhibit circumferential variations and have been demonstrated to be significant contributors to noise generation. However, a comprehensive and effective model that considers multiple long-wave deviations simultaneously has seldom been studied. To fill this gap, a new numerical model of spur gear systems with long-wave deviations is established, in which the coupling effects of both tooth pitch deviation and geometric eccentricity are taken into consideration. A time-varying mesh stiffness (TVMS) analytical model for spur gear pairs is established, which considers the relationship of errors between pitch deviation and eccentricity. The time-varying contact state of the gear pair under periodic long-wave deviations is also analyzed. A translation-torsion coupled dynamic model is established to investigate the excitation behavior of gear pairs with periodic long-wave deviations. The accuracy of the TVMS and the dynamic model is verified through comparisons with reference and experimental results. Results show that gear pairs with long-wave deviations exhibit periodic fluctuations in TVMS compared to ideal gear pairs, accompanied by phase differences. The mesh stiffness impact phenomenon becomes less pronounced for higher gear precision under lower-load conditions. Conversely, the periodic vibration characteristics induced by eccentricity become less prominent for the lower gear precision level. The excitation behavior of the gear pair with pitch deviation is masked by eccentricity at lower rotational orders, but it still dominates at higher rotational orders. This method can predict the dynamic characteristics of gear transmission systems with periodic long-wave deviations, providing theoretical guidance for reducing the vibration and noise levels.

Control of a BLDC Motor of an Electric Vehicle Powered by a Photovoltaic System based on Fuzzy Logic MPPT (FLC-MPPT)

Photovoltaic Systems (PV) represent a viable solution for converting solar energy into electricity without emitting harmful gases. This technology remains highly sought-after in the market, primarily due to its renewable characteristics and the absence of movable components, which renders it a low-maintenance option. This produced energy can be stored in batteries tobe used for example in operating electric vehicles. If the generated voltage is inadequate or requires regulation, a boost converter may be employed or a buck boost To manage energy during storage and discharge to provide the energy needed to run the induction motor. In this paper, we proposed the field-oriented control as an approach for controlling the speed of BLDC Motor drive electrical vehicles to improve the overall effectiveness of the proposed system, The BLDC Motor is powered by battery storage from a photovoltaic system. Furthermore, this work also addresses the specifics of modeling the Fuzzy logic control MPPT (FLC-MPPT) used for the energy management system (PV and batteries), as well as the proposed control approach for the electric vehicle motor, which are subsequently simulated in the MatLab environment.

026. Utilizing Pre-Existing Lacerations for Frontal Bone Fracture Management: A Case Report

Background: Patients with fractures of the frontal bone use the coronal incision approach to expose the anterior cranial vault, including the forehead. The flap allows for widespread exposure of the fractures, facilitating access for the removal of segmental fractures and hematoma evacuation. Maintaining sufficient pedicle width is crucial to reduce the risk of unintentional arterial damage and to ensure proper venous drainage. The objective of this study was to document the surgical approach for segmental fracture removal under a forehead pedicle flap. Case: This case presents a 22-year-old male with moderate traumatic brain injury, who had two lacerations on his forehead and showed an open depressed fracture of the frontal bone after a motor vehicle collision. The patient experienced loss of consciousness and a history of vomiting. Imaging revealed intracerebral hemorrhage in the frontal region and a depressed fracture of the frontal bone. Intraoperative findings revealed the fracture site through the previous laceration incision. The fracture was clearly evaluated by the surgeon using tools to lift the skin between the two incisions. Conclusion: Despite the access for segment fracture removal being conducted through a pre-existing laceration, the patient outcomes were favorable, and no complications were reported.

Pediatric Cervical Spine Trauma: A Narrative Review.

Narrative review. To provide an updated overview of pediatric cervical spine trauma. Pediatric cervical spine trauma can cause debilitating morbidity and mortality and neurological impairment. The unique anatomic features of the developing cervical spine can predispose children to injuries. We reviewed the pediatric cervical spine trauma literature in PubMed and EMBASE. Pediatric cervical spine injury occurs in 1%-2% of pediatric trauma. The most frequent cause is motor vehicle collisions, with sports-related injuries being more common in older children. Larger head-to-body ratios and tissue elasticity can predispose young children to a greater risk of injury higher in the craniocervical junction and cervical spine. Standardized protocols and classification systems, such as the Pediatric Cervical Spine Clearance Working Group protocol and the AO Spine Injury and Subaxial Cervical Spine Injury Classifications, are valuable in triage as well as for assessing the need for operative versus nonoperative management. In general, operative approaches and principles are similar to those in adults, with modern instrumentation and fusion techniques achieving high rates of successful arthrodesis. Effective management and treatment of pediatric cervical spine injuries depends on early and accurate diagnosis, a thorough understanding of pediatric spinal anatomy, and a versatile surgical armamentarium.

Expandable Intravertebral Titanium Implants for Thoracolumbar Burst Fractures Without Neurological Deficits

Objective: A thoracolumbar burst fracture (TLBF) is defined as the failure of the anterior and middle columns of the vertebra due to high-energy trauma, such as motor vehicle collisions and falls from heights. Debate has continued for decades regarding the standard treatment, especially for TLBFs without neurological deficits (TLBF-WONDs). The aim of this study was to understand the role of expandable intravertebral titanium implants (EITIs) in treating TLBF-WONDs.Methods: We included patients aged 18–65 years who presented at our hospital Emergency Department with severe back pain (visual analogue scale [VAS] score ≥ 8), were neurologically intact, were diagnosed with TLBF-WOND by either computed tomography or magnetic resonance imaging, underwent percutaneous bilateral transpedicular EITI implantation, and were followed-up for ≥12 months. Radiological and clinical outcomes were analyzed.Results: Thirty patients satisfied the study inclusion criteria, including 9 men and 21 women, with an average age of 48.2 years. Thirteen A3 and 17 A4 burst fractures were included. The mean duration of hospitalization was 3.3 days. The mean follow-up period was 4.4 years. All patients exhibited significant improvements in radiographical (anterior, middle, and posterior vertebral heights); vertebral kyphotic angle (p<0.001); and functional outcomes (VAS and Oswestry Disability Index scores, p<0.001). One case of cement leakage into the paraspinal muscle was observed; however, no major complications occurred.Conclusion: Percutaneous bilateral transpedicular EITI placement with cement augmentation under local anesthesia may be an effective strategy for the treatment of high-energy traumatic TLBFs with neurological integrity.

An Experimental Investigations on Design and Weight Optimization for a Light Motor Vehicle (LMV) Drive Shaft Using a Composite Material Aluminum and Glass Fiber (Al + GF)

Aluminum is primarily used in Metal Composites because of its lighter weight and higher strength. Glass fibers are wound around an aluminum shaft to create the composite. ANSYS results determine the relative amounts of aluminum and Eglass fiber in each shaft. The purpose of this study is to use a torsion test to evaluate the mechanical performance of a composite shaft composed of aluminum and glass fiber. The results are carefully examined for different combinations of glass fiber layers and aluminum layers. When the weight proportion of aluminum in the composite increases, the mechanical properties of the composites improve.

Understanding the Factors Affecting Traffic Danger for Children: Insights From Focus Group Discussions

Children’s safety on urban roads is a critical concern with young pedestrians and cyclists being among the most vulnerable groups to traffic-related dangers. The prioritization of motor vehicle traffic in road infrastructure poses significant risks to child pedestrians and cyclists navigating city streets. Furthermore, children’s independent mobility has been restricted due to traffic danger and their parents’ concerns about it. Given the important implications of this issue, a serious gap was identified in that no measure of traffic danger exists, with outcomes (e.g., collisions) being used as a proxy. Identifying factors contributing to traffic danger, how they interact, and how they impact traffic are imperative to identify where mitigation is needed to address these problems. This article delves into the complexities of traffic risks for children, focusing on intersections and streets. Six focus groups, including experts (<em>n</em> = 3), parents (<em>n</em> = 2), and children aged 8 to 12 (<em>n</em> = 1), were conducted to gather insights on factors impacting traffic danger. Thematic analysis revealed eight key themes, highlighting the importance of addressing traffic volume, speed, vehicle size, road design, driver behavior, visibility, and land use. These findings contribute to a comprehensive framework for understanding traffic danger for children. Additionally, the article examines how stakeholders’ perspectives align with standard measures of traffic danger in the literature.

Legal Protection for Creditors Who Recipient of Motor Vehicle Fiduciaries After Constitutional Court Decision Number 18/PUU-XVII/2019 & Number 2/PUU-XIX/2021 (Study at BRI Finance Malang Branch)

Fiduciary is a material guarantee which is a development of other material guarantees, namely Pawning. This development is a living need in society because pawning collateral which requires control of the pledged collateral object by the creditor is felt to be less supportive of business because the debtor cannot benefit from the collateral object so material collateral is needed which is more beneficial for the debtor but also the creditor's interests can still be protected. Execution of fiduciary guarantees can be carried out in accordance with article 29 UUJF, namely if the debtor or fiduciary person breaks his promise, the execution of the object that is the object of fiduciary guarantee point 1 above is the priority given by the material guarantee institution which is referred to as Parate execution, which is regulated in Article 15 paragraph (3) of the Fiduciary Guarantee Law (hereinafter abbreviated to "UUJF") which states that "If the debtor breaks his promise, the fiduciary recipient has the right to sell the object that is the object of the fiduciary guarantee under his own authority." The research method used is the Socio Legal Research Method or commonly used as empirical juridical research. Empirical legal research, namely data obtained directly from the community as the first source through field research. The research location is at the BRI Finance Malang Branch Office which is one of BRI's subsidiary entities which operates in the financing sector located in Malang City. One of the financing products from BRI Finance is Multipurpose Motor Vehicle Ownership Credit where the collateral is a motor vehicle tied to the institution fiduciary material guarantee. The results of the research show that the execution of credit collateral in the form of a motor vehicle tied to a fiduciary with the Constitutional Court decision Number 18/PUU/XVII/2019 which is confirmed by the Constitutional Court decision No.2/PUU-XIX/2021 becomes weaker because the creditor's preference rights are limited. The institution granted fiduciary material guarantees in the form of an execution parate cannot be carried out unilaterally because it must obtain the debtor's approval regarding the element of breach of contract/default and also the voluntary handover of fiduciary objects

Pengaruh Kesadaran Wajib Pajak, Pengatahuan Pajak, Sanksi Pajak, dan Tax Amnesty terhadap Kapatuhan Wajib Pajak Kendaraan Bermotor Roda Empat di Kota Kupang dengan Sosialisasi Pajak sebagai Variabel Moderasi (Studi di SAMSAT Kota Kupang)

This research aims to determine the influence of taxpayer awareness, taxpayer knowledge, tax sanctions and tax amnesty on tax socialization and motor vehicle taxpayer compliance in Kupang City. This research is included in the quantitative research category. The research results show that taxpayer responses to tax amnesty, tax sanctions, taxpayer awareness, and taxpayer compliance with four-wheeled motorized vehicles are positive. Factors that have a major influence on motor vehicle taxpayer compliance are: tax amnesty, tax knowledge, tax sanctions, and taxpayer awareness. The influence of taxpayer awareness, tax knowledge, and tax sanctions on motor vehicle taxpayer compliance can be mitigated by tax socialization. However, the effect of the tax amnesty on motor vehicle taxpayer compliance cannot be mitigated by tax socialization.
