Head injury AND fit

BACKGROUND: The severity, progression, and outcomes of motor and non-motor symptoms in Parkinson's disease (PD) are quite variable. Following PD cohorts holds promise for identifying predictors of disease severity and progression. METHODS: PD patients ( N  = 871) were enrolled at five sites. Enrollment occurred within 5 years of initial motor symptom onset. Disease progression was assessed annually for 2-to-10 years after onset. Group-based trajectory modeling was used to identify groups differing in disease progression...

OBJECTIVE: To examine whether individuals who have had one exposure to lifetime subconcussive impacts differ from those who have had multiple subconcussive exposures or those who have never had any injury to the head or neck in their report of neurobehavioral symptoms. METHOD: 458 adults from the continental U.S., Spain, and Latin America participated in an online survey that included the Ohio State University Traumatic Brain Injury Identification Method Self- Administered-Brief (OSU TBI-ID SAB), which assesses lifetime exposure to Traumatic Brain Injury, and the Neurobehavioral Symptom Inventory (NSI), a measure of symptoms commonly observed after head injury...

INTRODUCTION: Electric personal mobility devices (ePMDs), as well as crashes involving ePMDs, have been on the rise all over the world. The objectives of this study were: (a) to summarize the literature based on a narrow definition of ePMD (excluding e-bikes) and (b) to sort out the results to fit into a psychological and behavioral framework. The available literature was sorted into three main categories: the behaviors of ePMD drivers, their antecedents, and their consequences. METHOD: A narrative review of the literature was carried out in 101 documents published between January 2018 and July 2021...

BACKGROUND: Engaging Hill-Sachs lesions (HSLs) pose a significant risk for failure of surgical repair of recurrent anterior shoulder instability. Reconstruction with fresh osteochondral allograft (OCA) has been proposed as a treatment for large HSLs. PURPOSE: To determine the optimal characteristics of talus OCA bone plugs in a computer-simulated HSL model. STUDY DESIGN: Descriptive laboratory study; Level of evidence, 6. METHODS: Included were 132 patients with recurrent anterior instability with visible HSLs; patients who had multidirectional instability or previous shoulder surgery were excluded...

This paper studies the active force characteristics of the neck muscles under the condition of rapid braking, which can provide theoretical support for reducing the neck injury of pilots when carrier-based aircraft blocks the landing. We carried out static loading and real vehicle braking experiments under rapid braking conditions, collected the active contraction force and electromyography (EMG) signals of neck muscles, and analyzed the response characteristics of neck muscle active force response. The results showed that the head and neck forward tilt time was delayed and the amplitude decreased during neck muscle pre-tightening...

BACKGROUND: Anatomic restoration of the humeral head is critical for successful shoulder replacement. Accurate measurements of the humeral head are essential for anatomic substitution. PURPOSE: To evaluate whether a best-fit circle of the humeral head, as determined from different projections of plain radiographs, can predict the humeral head implant size for either the left or right shoulder. STUDY DESIGN: Descriptive laboratory study. METHODS: Bilateral shoulder radiographs of 200 patients without arthropathy or other abnormal findings of the humeral head were evaluated...

The human dura mater is known to impact vastly traumatic brain injury mechanopathology. In spite of this involvement, dura mater is typically neglected in computational and physical human head models. The lack of location-dependent microstructural and related mechanical data of dura mater may be considered a rationale behind this simplification. The anisotropic nature of dura mater under various loading conditions so far remains unelucidated. Furthermore, principal collagen fiber orientation is yet to be quantified for a morpho-mechanically-informed material model on the dura mater...

Metoprolol, a drug for hypertension and cardiovascular diseases, has become a contaminant of emerging concern because of its frequent detection in various environmental matrices globally. The dwindling in the biodiversity of useful insects owing to increasing presence of environmental chemicals is currently a great interest to the scientific community. In the current research, the toxicological impact of ecologically relevant concentrations of metoprolol at 0, 0.05, 0.1, 0.25, and 0.5 μg/L on Nauphoeta cinerea nymphs following exposure for 42 consecutive days was evaluated...

BACKGROUND: Adolescent use of substances and injury experiences such as head injury have become increasingly prevalent. However, information regarding their association and the potential pathways linking them remains limited. This study examined the association between substance use and injuries, emphasizing the mediating role of interpersonal violence among adolescents. METHODS: We employed a multi-country analysis of Global School-based Health Surveys of 122,945 in-school adolescents aged 11-18 from 29 countries...

AIMS: The aim of this study was to analyze how proximal radial neck resorption (PRNR) starts and progresses radiologically in two types of press-fit radial head arthroplasties (RHAs), and to investigate its clinical relevance. METHODS: A total of 97 patients with RHA were analyzed: 56 received a bipolar RHA (Group 1) while 41 received an anatomical implant (Group 2). Radiographs were performed postoperatively and after three, six, nine, and 12 weeks, six, nine, 12, 18, and 24 months, and annually thereafter...

OBJECTIVE: Pediatric clinicians caring for children with acquired brain injury have noted that many individuals requiring assistive technology (AT) go unserved or face delays until devices are obtained, with potential adverse implications for recovery and development. In this article we map the pathways by which AT is prescribed and assess delays and barriers to access. METHODS: We conducted a retrospective chart review of patients with moderate to severe brain injury admitted to Blythedale Children's Hospital over a 2-year period using a database drawn from the medical record...

Limited research has examined the symptom sequelae of head injuries in women survivors of intimate partner violence (IPV), despite this community being at increased risk of neurotrauma due to partner abuse. The current study compared post-concussion symptom severity between women with and without IPV-related head injuries. Women were recruited from court jurisdictions in Kentucky, USA after receiving a protective order for partner abuse. The sample included 286 women with no prior head injuries [age: M(SD)=31...

BACKGROUND: Despite improved outcomes, failure or nonhealing of graft materials has been reported after superior capsular reconstruction (SCR) for massive irreparable rotator cuff tears. PURPOSE: To evaluate the short-term clinical and radiological outcomes of a novel technique for SCR using an Achilles tendon-bone allograft. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: We performed a retrospective review of patients who underwent SCR using an Achilles tendon-bone allograft with the modified keyhole technique and who had a minimum follow-up of 2 years...

Field-evolved resistance of the western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, to Bacillus thuringiensis Berliner (Bt) proteins Cry3Bb1 and Cry34/35Ab1 (now classified as Gpp34Ab1/Tpp35Ab1) expressed in the pyramid SmartStax® has been documented in areas of the United States (U.S.) Corn Belt. SmartStax® PRO is a recently registered rootworm-active pyramid containing the same Bt proteins expressed in SmartStax® plus DvSnf7 dsRNA. Little to no published data is available comparing efficacy of the technologies or potential effects of dietary exposure on adult WCR fitness...

PURPOSE: Military risk factors such as blast exposure, noise exposure, head trauma, and neurotoxin exposure place Service members and Veterans at risk for deficits associated with auditory processing dysfunction. However, there is no clinical guidance specific to the treatment of auditory processing deficits in this unique population. We provide an overview of available treatments and their limited supporting evidence for use in adults, emphasizing the need for multidisciplinary case management and interdisciplinary research to support evidence-based solutions...

Truck-involved crashes, especially truck-car crashes, are associated with serious and even fatal injuries, thus necessitating an in-depth analysis. Prior research focused solely on examining the injury severity of truck drivers or developed separate performance models for truck and car drivers. However, the severity of injuries to both drivers in the same truck-car crash may be interrelated, and influencing factors of injury severities sustained by the two parties may differ. To address these concerns, a random parameter bivariate probit model with heterogeneity in means (RPBPHM) is applied to examine factors affecting the injury severity of both drivers in the same truck-car crash and how these factors change over the years...

To determine the diagnostic bias between clinical and forensic radiology in cases of nonfatal hanging and determine and describe typical underreported imaging findings. In a retrospective, single-center study, all patients admitted for attempted suicide with near-hanging or fatal hanging between January 2008 and December 2020 who received CT or MRI of head and neck were reviewed and missed findings in the original report were documented. A binary regression with disagreement as dependent variable was fitted for the imaging modality, fatality, age, and sex...

INTRODUCTION: The head and face, due to their prominent positions, are at risk of intentional and unintentional injuries in the majority of competitive sports. There are regional preferences for sports and differences in infrastructural facilities. The majority of the recommendations for sports have been based on the studies conducted in the western world. Hence, this systematic review aimed to estimate the prevalence of sports-related orofacial and dental injuries in professional-sportspersons living in Asian countries...

UNLABELLED: A prospective observational study was done with the aim to analyze the difficulties during decannulation of tracheostomized head injury patients and to devise a sound protocol for decannulation. It was done over 2 years in a tertiary care Army Hospital with 40 tracheostomized head injury cases in the age group of 10-70 years. Once the indication of tracheostomy was over, their Glasgow Coma Scale score, airway adequacy, phonation, swallowing, cough reflex, and lung pathology were assessed...
