RESUMO
BACKGROUND: Although post-traumatic stress disorder (PTSD) and depression screening are recommended for traumatic injury patients, routine screening is still uncommon. Salivary inflammatory biomarkers have biological plausibility and potential feasibility and acceptability for screening. This study tested prospective associations between several salivary inflammatory biomarkers (proinflammatory cytokines interleukin-1ß, interleukin-6, tumor necrosis factor-α; and C-reactive protein), collected during hospitalization and PTSD and depressive symptoms at 5-month follow-up. METHODS: Adult traumatic injury patients (N = 696) at a major urban Level 1 trauma center provided salivary samples and completed PTSD and depressive symptom measures during days 0-13 of inpatient hospitalization. At 5-month follow-up, 368 patients (77 % male, 23 % female) completed the Clinician-Administered PTSD Scale for DSM-IV and the Self-rated Inventory of Depressive Symptomatology. Analyses focused on a latent inflammatory cytokine factor and C-reactive protein at baseline predicting 5-month PTSD and depression symptom outcomes and included baseline symptom levels as covariates. RESULTS: A latent factor representing proinflammatory cytokines was not related to 5-month PTSD or depressive symptom severity. Higher salivary CRP was related to greater PTSD symptom severity (ß = .10, p = .03) at 5-month follow-up and more severity in the following depressive symptoms: changes in weight and appetite, bodily complaints, and constipation/diarrhea (ß's from .14 to .16, p's from .004 -.03). CONCLUSION: In a primarily Latine and Black trauma patient sample, salivary CRP measured after traumatic injury was related to greater PTSD symptom severity and severity in several depressive symptom clusters. Our preliminary findings suggest that salivary or systemic CRP may be useful to include in models predicting post-trauma psychopathology.

Ballistic shields protect users from a variety of threats, including projectiles. Shield back-face deformation (BFD) is the result of the shield deflecting or absorbing a projectile and deforming toward the user. Back-face deformation can result in localized blunt loading to the upper extremity, where the shield is supported by the user. Two vulnerable locations along the upper extremity were investigated-the wrist and elbow-on eight postmortem human subjects (PMHS) using a pneumatic impacting apparatus for investigating the fracture threshold as a result of behind shield blunt trauma (BSBT). Impacting parameters were established by subjecting an augmented WorldSID anthropomorphic test device (ATD) positioned behind a ballistic shield to ballistic impacts. These data were used to form the impact parameters applied to PMHS, where the wrist most frequently fractured at the distal radius and the elbow most frequently fractured at the radial head. The fracture threshold for the wrist was 5663±1386 N (mean±standard deviation), higher than the elbow at 4765±894 N (though not significantly, p = 0.15). The failure impact velocity for wrist impacts was 17.7±2.1 m/s, while for the elbow, the failure impact velocity was 19.5±0.9 m/s. An approximate 10% risk of fracture threshold was identified on the modified WorldSID ATD (no flesh analogue included) to inform future protective standards.

BACKGROUND: Increased survival from traumatic injury has led to a higher demand for follow-up care when patients are discharged from hospital. It is currently unclear how follow-up care following major trauma is provided to patients, and how, when, and to whom follow-up services are delivered. The aim of this study was to describe the current follow-up care provided to patients and their families who have experienced major traumatic injury in Australia and New Zealand (ANZ). METHODS: Informed by Donabedian's 'Evaluating the Quality of Medical Care' model and the Institute of Medicine's Six Domains of Healthcare Quality, a cross-sectional online survey was developed in conjunction with trauma experts. Their responses informed the final survey which was distributed to key personnel in 71 hospitals in Australia and New Zealand that (i) delivered trauma care to patients, (ii) provided data to the Australasian Trauma Registry, or (iii) were a Trauma Centre. RESULTS: Data were received from 38/71 (53.5%) hospitals. Most were Level 1 trauma centres (n = 23, 60.5%); 76% (n = 16) follow-up services were permanently funded. Follow-up services were led by a range of health professionals with over 60% (n = 19) identifying as trauma specialists. Patient inclusion criteria varied; only one service allowed self-referral (3.3%). Follow-up was within two weeks of acute care discharge in 53% (n = 16) of services. Care activities focused on physical health; psychosocial assessments were the least common. Most services provided care for adults and paediatric trauma (60.5%, n = 23); no service incorporated follow-up for family members. Evaluation of follow-up care was largely as part of a health service initiative; only three sites stated evaluation was specific to trauma follow-up. CONCLUSION: Follow-up care is provided by trauma specialists and predominantly focuses on the physical health of the patients affected by major traumatic injury. Variations exist in terms of patient selection, reason for follow-up and care activities delivered with gaps in the provision of psychosocial and family health services identified. Currently, evaluation of trauma follow-up care is limited, indicating a need for further development to ensure that the care delivered is safe, effective and beneficial to patients, families and healthcare organisations.

Neuroinflammation has a significant impact on different pathologies, such as stroke or spinal cord injury, intervening in their pathophysiology: expansion, progression, and resolution. Neuroinflammation involves oxidative stress, damage, and cell death, playing an important role in neuroplasticity and motor dysfunction by affecting the neuronal connection responsible for motor control. The diagnosis of this pathology is performed using neuroimaging techniques and molecular diagnostics based on identifying and measuring signaling molecules or specific markers. In parallel, new therapeutic targets are being investigated via the use of bionanomaterials and electrostimulation to modulate the neuroinflammatory response. These novel diagnostic and therapeutic strategies have the potential to facilitate the development of anticipatory patterns and deliver the most beneficial treatment to improve patients' quality of life and directly impact their motor skills. However, important challenges remain to be solved. Hence, the goal of this study was to review the implication of neuroinflammation in the evolution of motor function in stroke and trauma patients, with a particular focus on novel methods and potential biomarkers to aid clinicians in diagnosis, treatment, and therapy. A specific analysis of the strengths, weaknesses, threats, and opportunities was conducted, highlighting the key challenges to be faced in the coming years.
RESUMO
Background: Several studies have linked traumatic injury and cardiovascular disease. However, few studies have investigated the associations between traumatic injury and cardiovascular disease subtypes. We aimed to prospectively examine the association between traumatic injury and the risk of incident myocardial infarction (MI) and stroke. Methods: This study was based on a prospective cohort study that included 13,973 patients who had been hospitalized for traumatic injuries from 1980 to 2020. We randomly selected 4 uninjured participants from the cohort study for each patient as controls matched by age ( ± 3 years) and sex. All participants were free of MI and stroke at enrollment. Cox regression was used to examine the association between traumatic injury and incident MI and stroke. Results: During a median follow-up period of 13.5 years, 1032 cases of MI and 4068 cases of stroke were recorded. After multivariable adjustment, relative to controls, patients with severe injury had the highest hazard ratio (HR) for MI (HR = 1.93; 95% CI: 1.26-2.96) and stroke (HR = 1.60; 95% CI: 1.25-2.05). The HRs of MI and stroke were 0.97 (0.81-1.17) and 1.11 (1.02-1.21) for patients with mild injury and 1.28 (0.97-1.69) and 1.22 (1.06 to 1.41) for patients with moderate injury. Additionally, patients with older age at injury and chest injury had a higher HR for MI and stroke (p-interaction < 0.05). Conclusions: Traumatic injury appears to be associated with an increased risk of incident MI and stroke. Therefore, early screening and prevention of MI and stroke following a traumatic injury are needed.
RESUMO
BACKGROUND: Racial/ethnic differences in mental health outcomes after a traumatic event have been reported. Less is known about factors that explain these differences. We examined whether pre-, peri-, and post-trauma risk factors explained racial/ethnic differences in acute and longer-term posttraumatic stress disorder (PTSD), depression, and anxiety symptoms in patients hospitalized following traumatic injury or illness. METHODS: PTSD, depression, and anxiety symptoms were assessed during hospitalization and 2 and 6 months later among 1310 adult patients (6.95% Asian, 14.96% Latinx, 23.66% Black, 4.58% multiracial, and 49.85% White). Individual growth curve models examined racial/ethnic differences in PTSD, depression, and anxiety symptoms at each time point and in their rate of change over time, and whether pre-, peri-, and post-trauma risk factors explained these differences. RESULTS: Latinx, Black, and multiracial patients had higher acute PTSD symptoms than White patients, which remained higher 2 and 6 months post-hospitalization for Black and multiracial patients. PTSD symptoms were also found to improve faster among Latinx than White patients. Risk factors accounted for most racial/ethnic differences, although Latinx patients showed lower 6-month PTSD symptoms and Black patients lower acute and 2-month depression and anxiety symptoms after accounting for risk factors. Everyday discrimination, financial stress, past mental health problems, and social constraints were related to these differences. CONCLUSION: Racial/ethnic differences in risk factors explained most differences in acute and longer-term PTSD, depression, and anxiety symptoms. Understanding how these risk factors relate to posttraumatic symptoms could help reduce disparities by facilitating early identification of patients at risk for mental health problems.

INTRODUCTION: Crises like the COVID-19 pandemic create blood product shortages. Patients requiring transfusions are placed at risk and institutions may need to judiciously administer blood during massive blood transfusions protocols (MTP). The purpose of this study is to provide data-driven guidance for the modification of MTP when the blood supply is severely limited. METHODS: This is a retrospective cohort study of 47 Level I and II trauma centers (TC) within a single healthcare system whose patients received MTP from 2017 to 2019. All TC used a unifying MTP protocol for balanced blood product transfusions. The primary outcome was mortality as a function of volume of blood transfused and age. Hemoglobin thresholds and measures of futility were also estimated. Risk-adjusted analyses were performed using multivariable and hierarchical regression to account for confounders and hospital variation. RESULTS: Proposed MTP maximum volume thresholds for three age groupings are as follows: 60 units for ages 16-30 y, 48 units for ages 31-55 y, and 24 units for >55 y. The range of mortality under the transfusion threshold was 30%-36% but doubled to 67-77% when the threshold was exceeded. Hemoglobin concentration differences relative to survival were clinically nonsignificant. Prehospital measures of futility were prehospital cardiac arrest and nonreactive pupils. In hospital risk factors of futility were mid-line shift on brain CT and cardiopulmonary arrest. CONCLUSIONS: Establishing MTP threshold practices under blood shortage conditions, such as the COVID pandemic, could sustain blood availability by following relative thresholds for MTP use according to age groups and key risk factors.

INTRODUCTION: The objective of this study was to evaluate the performance of the Healthy Aging Brain Care Monitor (HABC-M) as a patient-reported outcome tool to measure cognitive, functional, and psychological symptoms among older adults who sustained non-neurologic injuries requiring hospital admission. METHODS: We used data from a multicenter randomized controlled trial to evaluate the utility of the HABC-M Self-Report version in older patients recovering from traumatic injuries. A total of 143 patients without cognitive impairment were included in the analysis. Cronbach's alpha was used to measure the internal consistency, and Spearman's rank correlation test was used to evaluate the relationship of the HABC-M with standard measures of cognitive, functional, and psychological outcomes. RESULTS: The HABC-M subscales and the total scale showed satisfactory internal consistency (Cronbach's alpha = 0.64 to 0.77). The HABC-M cognitive subscale did not correlate with the Mini-Mental State Examination. The HABC-M functional and psychological subscales correlated with corresponding standard reference measures (|rs| = 0.24-0.59). CONCLUSIONS: The HABC-M Self-Report version is a practical alternative to administering multiple surveys to monitor functional and psychological sequelae in older patients recovering from recent non-neurologic injuries. Its clinical application may facilitate personalized, multidisciplinary care coordination among older trauma survivors without cognitive impairment.

OBJECTIVE: Electrical injury (EI) is a significant, multifaceted trauma often with multi-domain cognitive sequelae, even when the expected current path does not pass through the brain. Chronic pain (CP) research suggests pain may affect cognition directly and indirectly by influencing emotional distress which then impacts cognitive functioning. As chronic pain may be critical to understanding EI-related cognitive difficulties, the aims of the current study were: examine the direct and indirect effects of pain on cognition following EI and compare the relationship between pain and cognition in EI and CP populations. METHOD: This cross-sectional study used data from a clinical sample of 50 patients with EI (84.0% male; Mage = 43.7 years) administered standardized measures of pain (Pain Patient Profile), depression, and neurocognitive functioning. A CP comparison sample of 93 patients was also included. RESULTS: Higher pain levels were associated with poorer attention/processing speed and executive functioning performance among patients with EI. Depression was significantly correlated with pain and mediated the relationship between pain and attention/processing speed in patients with EI. When comparing the patients with EI and CP, the relationship between pain and cognition was similar for both clinical groups. CONCLUSIONS: Findings indicate that pain impacts mood and cognition in patients with EI, and the influence of pain and its effect on cognition should be considered in the assessment and treatment of patients who have experienced an electrical injury.

BACKGROUND: This study investigated the relationship between combat-related traumatic injury (CRTI) and its severity and predicted cardiovascular disease (CVD) risk. MATERIAL AND METHODS: This was an analysis of comparative 10-year predicted CVD risk (myocardial infarction, stroke or CVD-death) using the QRISK®3 scoring-system among adults recruited into the Armed Services Trauma Rehabilitation Outcome (ADVANCE) cohort study. Participants with CRTI were compared to uninjured servicemen frequency-matched by age, sex, rank, deployment (Afghanistan 2003-2014) and role. Injury severity was quantified using the New Injury Severity Score (NISS). RESULTS: One thousand one hundred forty four adult combat veterans were recruited, consisting of 579 injured (161 amputees) and 565 uninjured men of similar age ethnicity and time from deployment/injury. Significant mental illness (8.5% vs 4.4%; p = 0.006) and erectile dysfunction (11.6% vs 5.8%; p < 0.001) was more common, body mass index (28.1 ± 3.9 vs 27.4 ± 3.4 kg/m2; p = 0.001) higher and systolic blood pressure variability (median [IQR]) (1.7 [1.2-3.0] vs 2.1 [1.2-3.5] mmHg; p = 0.008) lower among the injured versus uninjured respectively. The relative risk (RR) of predicted CVD (versus the population expected risk) was higher (RR:1.67 [IQR 1.16-2.48]) among the injured amputees versus the injured non-amputees (RR:1.60 [1.13-2.43]) and uninjured groups (RR:1.52 [1.12-2.34]; overall p = 0.015). After adjustment for confounders CRTI, worsening injury severity (higher NISS, blast and traumatic amputation) were independently associated with QRISK®3 scores. CONCLUSION: CRTI and its worsening severity were independently associated with increased predicted 10-year CVD risk.

Major traumatic crush injuries are difficult to manage, with high morbidity, requiring prolonged, complex treatment with many procedures. Free-flap reconstruction is often used yet full functionality still may not be regained. In this case study of a traumatic crush injury of the anterior distal tibia, ankle and foot of a 48-year-old male patient, we opted for an alternative management strategy using a combination of a dynamic tissue system (DTS) and biological xenografts (porcine urinary bladder matrix and a multi-tissue platform). The DTS was kept in place in an outpatient setting for four weeks postoperatively and removed after that time. At the 3-month follow-up, the wound was significantly smaller at about 15% of the original size. The wound healed completely before 6-month follow-up. Our patient's traumatic crush injury was successfully healed using an alternative management strategy, DTS and biologic xenografts.

OBJECTIVE: Asymmetrical dimensions and nonlinear margins of a multilayered traumatic wound often preclude healing via primary intention. We present the case of an otherwise healthy 21-year-old male who sustained trauma following a boating accident. METHOD: The patient sustained three lacerations to the posterior thighs from the boat propeller. The most extensive wound measured 25×10×6cm of muscle extrusion with a divot fracture involving the posterior femur. RESULTS: Primary closure and restoration of muscle biomechanics was achieved using a combination of a dynamic tissue system (DTS) and porcine urinary bladder matrix (PUBM) xenograft. After 24 days of treatment in hospital, the patient was discharged without the need for home health, outpatient wound care, or ongoing negative pressure wound therapy. The patient recovered full function of the legs and was cleared for participation in all activities. CONCLUSION: This complex traumatic boat propeller injury presented many challenges, including a transverse orientation on the extremity, degree of muscle injury/extrusion, and significant soft tissue loss. The combined application of a DTS with PUBM biological xenograft achieved a primary myocutaneous closure without the need for skin graft or flap reconstruction by plastic surgery.

The blood-brain barrier (BBB) is a multicellular construct that regulates the diffusion and transport of metabolites, ions, toxins, and inflammatory mediators into and out of the central nervous system (CNS). Its integrity is essential for proper brain physiology, and its breakdown has been shown to contribute to neurological dysfunction. The BBB in vertebrates exists primarily through the coordination between endothelial cells, pericytes, and astrocytes, while invertebrates, which lack a vascularized circulatory system, typically have a barrier composed of glial cells that separate the CNS from humoral fluids. Notably, the invertebrate barrier is molecularly and functionally analogous to the vertebrate BBB, and the fruit fly, Drosophila melanogaster, is increasingly recognized as a useful model system in which to investigate barrier function. The most widely used technique to assess barrier function in the fly is the dye-exclusion assay, which involves monitoring the infiltration of a fluorescent-coupled dextran into the brain. In this study, we explore analytical and technical considerations of this procedure that yield a more reliable assessment of barrier function, and we validate our findings using a traumatic injury model. Together, we have identified parameters that optimize the dye-exclusion assay and provide an alternative framework for future studies examining barrier function in Drosophila.

BACKGROUND/AIM: In case of crown fractures after traumatic dental injuries, the affected teeth can be restored either with reattachment of the fractured fragment or with a direct composite restoration. So far, longevity data for reattachments and direct composite restorations with regard to different failure types (pulp necrosis and infection, restoration loss) are scarce. Therefore, the aim of this retrospective study was to evaluate the restorative and biological survival of reattached fragments and composite restorations after crown fractures in permanent teeth. MATERIAL AND METHODS: Dental records of patients treated between 2000 and 2018 were retrospectively analysed regarding the restoration (reattachment or direct composite restorations) of teeth with crown fractures. Survival (no further intervention) and restorative and/or biological failure of all restored teeth were recorded. Statistical analysis was performed using Kaplan-Meier statistics, and the mean annual failure rates for two and 5 years were calculated. Furthermore, the effect of potential risk factors on survival was assessed. Log-rank tests and univariate Cox regression models (likelihood ratio tests) were used to assess the univariate effect of all variables of interest. Variables with a p-value ≤.10 were included in a multivariate Cox regression model with shared frailty (p < .05). RESULTS: Overall, 164 patients with 235 teeth (uncomplicated crown fracture: N = 201, complicated crown fracture: N = 34) were included (1.6 ± 2.5 years observation time). Of these, 59 teeth were restored with reattachment of the fragment and 176 with a composite restoration. Overall, composite restorations had a significantly higher survival rate than reattachments (p = .002). The cumulative survival after 2 years was 42.9% and 65.0% for teeth treated with a reattachment (mAFR = 34.5%) and a composite restoration (mAFR = 19.3%), respectively. When differentiating between failure types, restoration failure and pulp necrosis were significantly more frequently detected in reattached crown fractures compared to composite restorations (restorative failure: p = .001; biological failure: p = .036). In the multivariate Cox regression model, the variable jaw and luxation significantly influenced the survival when the tooth was restored with a composite restoration. The survival was not influenced by the fracture type. CONCLUSIONS: Restorative and biological failures were more frequently detected when the tooth was restored with a reattached fragment compared to a direct composite restoration. Both, restoration failure and pulp necrosis with infection should be considered as frequent complications after restoration of crown-fractured teeth which emphasizes the necessity of regular and short follow-up intervals throughout the first 2 years.

INTRODUCTION: The Victims of Crime Advocacy and Recovery Program (VOCARP) provides advocacy, mental health resources, and educational materials. This study will report complications, readmissions, and recidivism among crime victims, and who used or did not use victim services. MATERIALS AND METHODS: Patients engaged with programming from 3/1/17 until 12/31/18 were included. Control groups were patients injured by violent trauma without VOCARP use (N = 212) and patients injured by unintentional injuries (N = 201). Readmissions, complications, reoperations, and trauma recidivism were reported. RESULTS: 1019 patients (83%) used VOCARP. VOCARP users were less often male (56% vs. 71%), less commonly married (12% vs. 41%), and had fewer gunshot wounds (GSWs, 26% vs. 37%) and sexual assaults (4.1% vs. 8%), all p < 0.05. Of all 1,423 patients, 6.6% had a readmission and 7.4% developed a complication. VOCARP patients had fewer complications (4.5% vs. 13.7%), infections (2% vs. 9%), wound healing problems (1% vs. 3.3%), and deep vein thromboses (0.3% vs. 1.9%), all p < 0.05, but no differences in unplanned operations (4.5%). GSW victims had the most complications, readmissions, and unplanned surgeries. Prior trauma recidivism was frequent among all groups, with crime victim patients having 40% prior violence-related injury (vs 9.0% control, p < 0.0001). Trauma recidivism following VOCARP use occurred in 8.5% (vs 5.7% for non-users, p = 0.16). CONCLUSION: Crime victims differ from other trauma patients, more often with younger age, single marital status, and unemployment at baseline. Complications were lower for VOCARP patients. GSW patients had the most complications, readmissions, and unplanned secondary procedures, representing a population for future attention.

A man in his early 60 s who worked at a waste disposal plant had fallen into the refuse pit and was immediately taken to the emergency department for treatment. After 8 days without recovering consciousness, the man died. Antemortem contrast-enhanced computed tomography at the emergency department indicated Stanford type B/DeBakey type IIIb aortic dissection. The autopsy showed a sharp and transverse intimal tear 0.6 cm in length in the aortic isthmus and fractures in the 5th-6th thoracic vertebrae. No structural abnormalities in arterial walls were noted on histopathological examination. The traumatic aortic dissection induced by falling is rare, compared with vehicle crash. Although the verification process was challenging, the cause of death was ultimately concluded as traumatic aortic dissection due to falling into the refuse pit. The following observations were cited as evidence: (1) the location and feature of the intimal tear, (2) the positional relationship between the impact site and the entry tear, and (3) the circumstance of clash impact onto the "cushion" of accumulated waste in the refuse pit. Inquiries into the cause of death, such as those made in this report, are required to provide detailed information on the circumstances of the accident, postmortem examinations, and careful consideration.

BACKGROUND: Up to 40% of patients with traumatic injury experience critical bleeding, many requiring transfusion of blood products. International transfusion guidelines recommend the use of viscoelastic testing to guide blood product replacement. We implemented a Point of Care ROTEM® blood test for trauma patients who present and initiate a trauma activation. OBJECTIVES: The aim of this study was to undertake an evaluation of the implementation data to identify factors which helped and hindered this new practice. METHODS: A sequential mixed-methods design was conducted to evaluate intervention implementation. The intervention was designed with interprofessional collaboration and incorporated education and skills training supplemented with a decision aide. Patients aged ≥ 18 years who met the trauma activation criteria were included. Data collection occurred throughout the 21-month implementation period inclusive of initial roll out, maintenance and sustainability and include the number of ROTEM® blood tests taken and clinical characteristics of patients. Individual interviews were conducted with health professionals with experience of the intervention after the implementation period was complete. RESULTS: A total of 1570 eligible patients were included. The number of patients who had a ROTEM® blood test taken increased over time to 63%. The proportion of patients having a ROTEM® blood test obtained was higher for major trauma patients (n=162, 66.9%) who were admitted to the Intensive Care Unit. Regression analysis found trauma service presence on arrival and the sustainability phase of implementation increased the likelihood of having a ROTEM® taken. Qualitative data suggest that a more tailored approach to intervention implementation would assist with adoption. CONCLUSION: Implementation of new practice requires careful planning and should be undertaken with input from end-users. Continuous evaluation is necessary to support ongoing implementation and sustainability. To ensure effective implementation occurs, complex interventions need to be made workable and integrated in everyday health care practice.

Uncontrolled hemorrhagic shock is the main cause of death in patients with traumatic injuries. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a rapidly performed and less-invasive treatment to stop bleeding. The REBOA balloon may be placed at the location of bleeding to achieve hemostasis. Prior to balloon placement, the indications for placement must be evaluated, including non-thoracic aortic trauma and non-traumatic patients with postpartum hemorrhage, and the appropriate sheath size (from 5 to 8 French) must be selected based on the bleeding site. As vascular injury of aortic dissection, rupture, or perforation may occur during the procedure, changes in hemodynamic parameters should be monitored. After balloon placement, ischemic complications due to blood flow occlusion such as lower extremity ischemia and acute renal failure should be tracked. After balloon removal, reperfusion injuries may occur, which can result in multiple organ failure, and should be observed closely. When caring for patients receiving REBOA, physicians should explain the procedure to their families to obtain informed consent. Also, nurses should prepare supplies and closely monitor changes in critical life signs to minimize the risks of hypotension, arrhythmia, and changes in consciousness during the procedure. After placement, the neurovascular and peripheral limbs "5P" (pain, pallor, paresthesia, pulselessness and paralysis) condition should be evaluated and recorded in detail. This treatment approach requires further study and research to assess the long-term impacts of placement and improve quality of care in these patients.

In the largest sample studied to date, white matter microstructural trajectories and their relation to persistent symptoms were examined after pediatric mild traumatic brain injury (mTBI). This prospective, longitudinal cohort study recruited children aged 8-16.99 years with mTBI or mild orthopedic injury (OI) from five pediatric emergency departments. Children's pre-injury and 1-month post-injury symptom ratings were used to classify mTBI with or without persistent symptoms. Children completed diffusion-weighted imaging at post-acute (2-33 days post-injury) and chronic (3 or 6 months via random assignment) post-injury assessments. Mean diffusivity (MD) and fractional anisotropy (FA) were derived for 18 white matter tracts in 560 children (362 mTBI/198 OI), 407 with longitudinal data. Superior longitudinal fasciculus FA was higher in mTBI without persistent symptoms relative to OI, d (95% confidence interval) = 0.31 to 0.37 (0.02, 0.68), across time. In younger children, MD of the anterior thalamic radiations was higher in mTBI with persistent symptoms relative to both mTBI without persistent symptoms, 1.43 (0.59, 2.27), and OI, 1.94 (1.07, 2.81). MD of the arcuate fasciculus, -0.58 (-1.04, -0.11), and superior longitudinal fasciculus, -0.49 (-0.90, -0.09) was lower in mTBI without persistent symptoms relative to OI at 6 months post-injury. White matter microstructural changes suggesting neuroinflammation and axonal swelling occurred chronically and continued 6 months post injury in children with mTBI, especially in younger children with persistent symptoms, relative to OI. White matter microstructure appears more organized in children without persistent symptoms, consistent with their better clinical outcomes.

In this report, the authors provide a contribution of PMCT in assessing the cause of death due to natural disasters. Here, the PMCT findings of 43 subjects who died during both landslide and flood were described. The post-mortem imaging revealed, clearly, traumatic injuries and/or the presence of foreign material in airways allowing to assess the cause of death of each subject, together with external inspection and the collected circumstantial data. Particularly, the PMCT has been helpful for characterization and localization of the clogging substance in airways providing findings on bronchial branches involvement. Moreover, the investigation offered detailed data on skeletal injuries in all anatomic districts and put in evidence both the precise fracturing site and the characteristics of fracture stubs for each bone fracture. This report supports the recommendation of the virtual autopsy in a case with several victims, as in natural disasters, and its role as an alternative diagnostic investigation when the standard autopsy is not feasible.
