METHODS: A realistic vehicle trial was conducted. Eight participants completed trials in both foggy and clear zones on the same roadway. Drivers' physiological and psychological properties were analyzed using gaze, saccade, pupil, and heart rate as primary indicators...

Muscle fatigue significantly impacts coordination, stability, and speed in daily activities. Accurate assessment of muscle fatigue is vital for effective exercise programs, injury prevention, and sports performance enhancement. Current methods mostly focus on individual muscles and strength evaluation, overlooking overall fatigue in multi-muscle movements. This study introduces a comprehensive muscle fatigue model using non-negative matrix factorization (NMF) weighting. NMF is employed to analyze the duration multi-muscle weight coefficient matrix (DMWCM) during synergistic movements, and four electromyographic (EMG) signal features in time, frequency, and complexity domains are selected...

BACKGROUND: Mental health (MH) problems in youth are prevalent, burdening, and frequently persistent. Despite the existence of effective treatment, the uptake of professional help is low, particularly due to attitudinal barriers. OBJECTIVE: This study evaluated the effectiveness and acceptability of 2 video-based microinterventions aimed at reducing barriers to MH treatment and increasing the likelihood of seeking professional help in young people. METHODS: This study was entirely web based and open access...

INTRODUCTION: Traumatic brain injury (TBI) is a leading cause of death and disability, often resulting in prolonged coma and disordered consciousness. There are currently gaps in understanding the factors affecting rehabilitation location and outcome after TBI. OBJECTIVE: To identify the impact of demographics, comorbidities, and complications on discharge disposition in adults with prolonged coma following TBI. DESIGN: Retrospective cohort study...

The impact of COVID-19 on sport and physical activity has been a subject of considerable interest and concern. Padel satisfies the desire for social interaction and a return to sport after a period of inactivity. The aim of this study is to show a correlation between return to sport and related injuries in a population of Padel players. The study was carried out in a survey mode, consisting of a questionnaire with four sections and fifty questions on the biographical data of the individual, lifestyle before and after the pandemic, knowledge and playing level of Padel and injuries...

OBJECTIVE: In the domain of competitive events, Latin dance athletes have always suffered competitive anxiety, which is a prevalent and prevailing psychological facet, in pre-, intra-, and post-competitive engagements. Usually, the implementation of systematic desensitization training is an efficacious approach to reduce competitive anxiety levels in routine sports to fortify psychological resilience of athletes (like swimming, volleyball, and basketball). This study focuses on the effect of systematic desensitization training on competition anxiety in the training of Latin dancers to establish good mental ability and promote the competitive ability of athletes...

This study aimed to investigate how overall competitive winningness in combat sports depended on patterns of victory and loss, as well as training habits. Competitors ( N  = 280) from several combat sports participated in the study. The online survey included questions on self-reported patterns of victory (and loss), training habits, general demographics (e.g., age), and sport-specific information (e.g., stage of career and competitive style). Overall, it was found across four models that reflected diversity of winningness in combat sports that the most important predictors of competitive winningness were loss by points (negative), loss by submission (negative), loss (negative) or victory (positive) by throw or technical fall, and loss (negative) or victory (positive) by knockout...

INTRODUCTION: While the U.S. has high quality data on firearm-related deaths, less information is available on those who arrive at trauma centers alive, especially those discharged from the emergency department. This study sought to describe characteristics of patients arriving to trauma centers alive following a firearm injury, postulating that significant differences in firearm injury intent might provide insights into injury prevention strategies. METHODS: This was a multi-center prospective cohort study of patients treated for firearm-related injuries at 128 U...

STUDY DESIGN: Cross-sectional survey of the Finnish population with spinal cord injury (SCI). OBJECTIVES: To explore the frequencies of perceived environmental barriers (EB) that made participation harder for the Finnish population with SCI and to compare the occurrence of perceived EBs by gender, age, time since injury, and injury severity. SETTING: Participants were recruited from the registers of the three SCI outpatient clinics responsible for the lifelong care of people with SCI in Finland...

Precise orchestration of cell fate determination underlies the success of scaffold-based skeletal regeneration. Despite extensive studies on mineralized parenchymal tissue rebuilding, regenerating and maintaining undifferentiated mesenchyme within calvarial bone remain very challenging with limited advances yet. Current knowledge has evidenced the indispensability of rebuilding suture mesenchymal stem cell niches to avoid severe brain or even systematic damage. But to date, the absence of promising therapeutic biomaterials/scaffolds remains...

Intestinal stem cells (ISCs) play a crucial role in the continuous self-renewal and recovery of the intestinal epithelium. In previous studies, we have revealed that the specific absence of Claudin-7 (Cldn-7) in intestinal epithelial cells (IECs) can lead to the development of spontaneous colitis. However, the mechanisms by which Cldn-7 maintains homeostasis in the colonic epithelium remain unclear. Therefore, in the present study, we used IEC- and ISC-specific Cldn-7 knockout mice to investigate the regulatory effects of Cldn-7 on colonic Lgr5+ stem cells in the mediation of colonic epithelial injury and repair under physiological and inflammatory conditions...

INTRODUCTION: Unintentional injury is the leading cause of death among children. Much can be gleaned from the adult literature in understanding the characteristics that lead to recidivism in efforts to establish interventions for prevention. Our study aims to evaluate the rates, demographics, and features of pediatric trauma recidivism. METHODS: This was a retrospective single-institution review at a level-1 pediatric trauma center of children and young adults (ages 0-28) with traumatic injuries from January 2008 to April 2023...

Acute kidney injury (AKI) is characterized by an abrupt decline of excretory kidney function. The incidence of AKI has increased in the past decades. Patients diagnosed with AKI often undergo diverse clinical trajectories, such as early or late recovery, relapses, and even a potential transition from AKI to chronic kidney disease (CKD). Although recent clinical studies have demonstrated a strong association between AKI and progression of CKD, our understanding of the complex relationship between AKI and CKD is still evolving...

BACKGROUND: In Lesch-Nyhan disease (LND), early dopamine deficiency is thought to contribute to dystonia and self-injury, gradually developing over the first years of life. Previous attempts to restore dopamine levels in older patients have been unsuccessful. Based on the hypothesis that very early dopamine replacement can prevent full phenotypic development, we treated three patients with LND from infancy with levodopa. METHODS: Levodopa/carbidopa (4:1) was started at age 11 to 13 months, aiming at escalating to 5 to 6 mg/kg levodopa per day...

BACKGROUND: The field of human expert performance teaches us that high quality, high-dose guided practice is required to make large gains in cognitively driven acts. The same also seems to be true for people with acquired brain injury, yet therapy services for people with aphasia (PWA) have traditionally not been designed with this in mind. Intensive Comprehensive Aphasia Programmes (ICAPs) are one way to address the chronic under-dosing of therapy that most PWA experience. AIMS: There are several ways to deliver an ICAP; here we describe two iterations of our Queen Square ICAP...

OBJECTIVE: To identify neurobehavioral symptom profiles among persons with chronic traumatic brain injury (TBI) using the Behavioral Assessment Screening Tool (BAST) and to consider participant characteristics that differ between profile groups. SETTING: Community. PARTICIPANTS: Participants (n = 615) were English-speaking adults (≥18) and had a self-reported history of at least one TBI of any severity. DESIGN: Secondary analysis of cross-sectional data...

INTRODUCTION: High rates of suicidal ideation (SI), suicide attempts (SA), and repetitive nonsuicidal self-injury (NSSI) among some ethnoracially minoritized United States youth populations may be related to adverse childhood experiences (ACEs) with structural roots. METHODS: Using the 2013-2019 Minnesota Student Surveys, we assessed associations of student-reported structural ACEs (parental incarceration, housing instability, food insecurity, and foster care involvement) with SI, SA, and repetitive NSSI within the past 12 months using multilevel logistic regression stratified by ethnoracial group (American Indian/Alaskan Native [AIAN], Hmong, other Asian, Black Latino, other Latino, Somali, other Black/African American [AA], Native Hawaiian/Pacific Islander [NHPI], and multiracial), and adjusted for sex, grade, ACEs experienced within one's household, mental health treatment, and perceived safety...

In 2021, there were 1.7 million suicide attempts in the US, with firearms being the most common method used, comprising more than 50% of attempts. We present a case report of delayed operative intervention for foreign body removal after a suicide attempt using a nail gun fired into the left hemi thorax. Initial conservative management was complicated by the delayed presentation of hemoptysis requiring surgical intervention. We hypothesize that the delay was secondary to foreign body migration. Initial management was attempted robotically, but dense adhesions were encountered, requiring conversion to an open thoracotomy...

While ample research has shown that sport injuries are associated with poor psychological status, scant attention has been given to changes in injured athletes' psychological status over the full course of recovery and return to sport. The aim of the present study was to prospectively investigate potential changes in injured athletes' psychological status across four phases of recovery and return to sport. A total of 38 severely injured adult competitive athletes (58% female; mean age 24.1 ± 7...

STUDY DESIGN: Qualitative Cohort Study. OBJECTIVES: Many people with long-term spinal cord injury (SCI) develop adaptation strategies to succeed. Understanding the factors that support their capacity to adapt and develop is important to enhance quality of life of others with SCI. This study aims to learn how these factors influence how people with SCI attain and maintain optimal quality of life as time since injury grows. SETTING: IL, USA...
