Inferior vena cava collapsibility index and trauma severity in elderly fall injuries.

OBJECTIVE: Falls are a serious cause of morbidity and mortality among older people. One of the underlying causes of falls is dehydration. Therefore, ultrasonography has become an essential tool for evaluating volume status in the emergency department. However, the effect of volume status on falls in older people has not been evaluated before. The aim of this study was to determine the relationship between the inferior vena cava collapsibility index and the injury severity score in older patients who presented with fall-related injuries to the emergency department. METHODS: A total of 66 patients were included in the study. The injury severity score was used as the trauma severity score, and the Edmonton Frail Scale was used as the frailty scale. Volume status was evaluated with inferior vena cava collapsibility index. The primary outcome measure was defined as the correlation between inferior vena cava collapsibility index and injury severity score. Secondary outcome measures were defined as the effect of inferior vena cava collapsibility index and injury severity score on hospitalization and mortality. RESULTS: There was no significant correlation between injury severity score and inferior vena cava collapsibility index (p=0.342). Neither inferior vena cava collapsibility index nor injury severity score was an indicator of the mortality of these patients. However, injury severity score was an indicator of hospitalization. The mean Edmonton Frail Scale score was an indicator of mortality among older people who experienced falls (p=0.002). CONCLUSION: Inferior vena cava collapsibility index cannot be used to predict trauma severity in older patients who have experienced falls admitted to the emergency department.

Mitochondrial dysfunction in platelets from severe trauma patients - A prospective case-control study.

INTRODUCTION: Trauma-induced coagulopathy (TIC) refers to an abnormal coagulation process, an imbalance between coagulation and fibrinolysis due to several pathological factors, such as haemorrhage and tissue injury. Platelet activation and subsequent clot formation are associated with mitochondrial activity, suggesting a possible role for mitochondria in TIC. Comprehensive studies of mitochondrial dysfunction in platelets from severe trauma patients have not yet been performed. METHODS: In this prospective case-control study, patients with severe trauma (ISS≥16) had venous blood samples taken at arrival to the Emergency Unit of a Level 1 Trauma Centre. Mitochondrial functional measurements (Oxygraph-2k, Oroboros) were performed to determine oxygen consumption in different respiratory states, the H2O2 production and extramitochondrial Ca2+ movements. In addition, standard laboratory and coagulation tests, viscoelastometry (ClotPro) and aggregometry (Multiplate) were performed. Measurements data were compared with age and sex matched healthy control patients. RESULTS: Severe trauma patients (n = 113) with a median age of 38 years (IQR, 20-51), a median ISS of 28 (IQR, 20-48) met our inclusion criteria. Oxidative phosphorylation in platelet mitochondria from severe trauma patients significantly decreased compared to controls (34.7 ± 8.8 pmol/s/mL vs. 48.0 ± 19.7 pmol/s/mL). The mitochondrial H2O2 production significantly increased and greater endogenous Ca2+ release was found in the polytrauma group. Consistent with these results, clotting time (CT) increased while maximum clot firmness (MCF) decreased with the EX-test and FIB-test in severe trauma samples. Multiplate aggregometry showed significantly decreased ADP-test (38 ± 12 AUC vs. 112 ± 14 AUC) and ASPI test (78 ± 22 AUC vs. 84 ± 28 AUC) also tended to decrease in mitochondria of polytrauma patients as compared with controls. Significant strong correlation has been demonstrated between mitochondrial OxPhos and MCF while it was negatively correlated with ISS (R2=0.448, P˂0.05), INR, CT and lactate level of patients. CONCLUSIONS: The present study revealed that severe trauma is associated with platelet mitochondrial dysfunction resulting in reduced ATP synthesis and impaired extramitochondrial Ca2+ movement. These factors are required for platelet activation, recruitment and clot stability likely thus, platelet mitochondrial dysfunction contributes to the development of TIC.

Outcomes of Extracorporeal Membrane Oxygenation in Acute Respiratory Distress Syndrome in Pediatric Trauma Patients.

IMPORTANCE: Acute respiratory distress syndrome (ARDS) is associated with high mortality and morbidity. Extracorporeal membrane oxygenation (ECMO) is one of the interventions that have been in practice for ARDS for decades. OBJECTIVES: The purpose of the study was to investigate the outcomes of ECMO in pediatric trauma patients who suffered from ARDS. DESIGN: Observational cohort study. SETTING AND PARTICIPANTS: The Trauma Quality Improvement Program database for years 2017 to 2019 and 2021 through 2022 was accessed for the study. All children younger than 18 years old who were admitted to the hospital after trauma and suffered from ARDS were included in the study. Other variables included in the study were patients' demographics, clinical characteristics, Injury Severity Score (ISS), Glasgow Coma Scale (GCS) score, comorbidities, and outcomes. MAIN OUTCOMES AND MEASURES: ECMO is the exposure, and the outcomes are in-hospital mortality and hospital complications (acute kidney injury [AKI], pneumonia and deep vein thrombosis [DVT]). RESULTS: Of 453 patients who qualified for the study, propensity score matching found 50 pairs of patients. There were no significant differences identified between the groups, ECMO+ vs. ECMO- on patients' age in years (16 yr; interquartile range [IQR], 13.25-17 yr vs. 16 yr [14.25-17 yr]), race (White; 62.0% vs. 66.0%), sex (male; 78% vs. 76%), ISS (23 [IQR, 9.25-34] vs. 22 [9.25-32]), and GCS (15 [IQR, 3-15] vs. 13.5 [3-15]), mechanism of injury; and comorbidities. There was no difference between the groups, ECMO+ vs. ECMO-, in-hospital mortality (10.0% vs. 20.0%; p = 0.302), hospital complications (AKI 12.0% vs. 2.0%; p = 0.131), pneumonia (10.0% vs. 20.0%; p = 0.182 > ), and DVT (16% vs. 6%; p = 0.228). CONCLUSIONS AND RELEVANCE: No difference in mortality was observed in injured children who suffered from the ARDS and were placed on ECMO when compared with patients who were not placed on ECMO. Patients with trauma and ARDS who require ECMO have comparable outcomes to those who do not receive ECMO. A larger sample size study is needed to find the exact benefit of ECMO in this patients' cohort.

Integrated landscape of plasma metabolism and proteome of patients with post-traumatic deep vein thrombosis.

Deep vein thrombosis (DVT) is a leading cause of morbidity and mortality after trauma. Here, we integrate plasma metabolomics and proteomics to evaluate the metabolic alterations and their function in up to 680 individuals with and without DVT after trauma (pt-DVT). We identify 28 metabolites and 2 clinical parameter clusters associated with pt-DVT. Then, we develop a panel of 9 metabolites (hexadecanedioic acid, pyruvic acid, L-Carnitine, serotonin, PE(P-18:1(11Z)/18:2(9Z,12Z)), 3-Hydroxycapric acid, 5,6-DHET, 3-Methoxybenzenepropanoic acid and pentanenitrile) that can predict pt-DVT with high performance, which can be verified in an independent cohort. Furthermore, the integration analysis of metabolomics and proteomics data indicates that the upregulation of glycolysis/gluconeogenesis-TCA cycle may promote thrombosis by regulating ROS levels in red blood cells, suggesting that interfering with this process might be potential therapeutic strategies for pt-DVT. Together, our study comprehensively delineates the metabolic and hematological dysregulations for pt-DVT, and provides potential biomarkers for early detection.

The UK resuscitative endovascular balloon occlusion of the aorta in trauma patients with life-threatening torso haemorrhage: the (UK-REBOA) multicentre RCT.

Background: The most common cause of preventable death after injury is haemorrhage. Resuscitative endovascular balloon occlusion of the aorta is intended to provide earlier, temporary haemorrhage control, to facilitate transfer to an operating theatre or interventional radiology suite for definitive haemostasis. Objective: To compare standard care plus resuscitative endovascular balloon occlusion of the aorta versus standard care in patients with exsanguinating haemorrhage in the emergency department. Design: Pragmatic, multicentre, Bayesian, group-sequential, registry-enabled, open-label, parallel-group randomised controlled trial to determine the clinical and cost-effectiveness of standard care plus resuscitative endovascular balloon occlusion of the aorta, compared to standard care alone. Setting: United Kingdom Major Trauma Centres. Participants: Trauma patients aged 16 years or older with confirmed or suspected life-threatening torso haemorrhage deemed amenable to adjunctive treatment with resuscitative endovascular balloon occlusion of the aorta. Interventions: Participants were randomly assigned 1 : 1 to: standard care, as expected in a major trauma centre standard care plus resuscitative endovascular balloon occlusion of the aorta. Main outcome measures: Primary: Mortality at 90 days. Secondary: Mortality at 6 months, while in hospital, and within 24, 6 and 3 hours; need for haemorrhage control procedures, time to commencement of haemorrhage procedure, complications, length of stay (hospital and intensive care unit-free days), blood product use. Health economic: Expected United Kingdom National Health Service perspective costs, life-years and quality-adjusted life-years, modelled over a lifetime horizon. Data sources: Case report forms, Trauma Audit and Research Network registry, NHS Digital (Hospital Episode Statistics and Office of National Statistics data). Results: Ninety patients were enrolled: 46 were randomised to standard care plus resuscitative endovascular balloon occlusion of the aorta and 44 to standard care. Mortality at 90 days was higher in the standard care plus resuscitative endovascular balloon occlusion of the aorta group (54%) compared to the standard care group (42%). The odds ratio was 1.58 (95% credible interval 0.72 to 3.52). The posterior probability of an odds ratio > 1 (indicating increased odds of death with resuscitative endovascular balloon occlusion of the aorta) was 86.9%. The overall effect did not change when an enthusiastic prior was used or when the estimate was adjusted for baseline characteristics. For the secondary outcomes (3, 6 and 24 hours mortality), the posterior probability that standard care plus resuscitative endovascular balloon occlusion of the aorta was harmful was higher than for the primary outcome. Additional analyses to account for intercurrent events did not change the direction of the estimate for mortality at any time point. Death due to haemorrhage was more common in the standard care plus resuscitative endovascular balloon occlusion of the aorta group than in the standard care group. There were no serious adverse device effects. Resuscitative endovascular balloon occlusion of the aorta is less costly (probability 99%), due to the competing mortality risk but also substantially less effective in terms of lifetime quality-adjusted life-years (probability 91%). Limitations: The size of the study reflects the relative infrequency of exsanguinating traumatic haemorrhage in the United Kingdom. There were some baseline imbalances between groups, but adjusted analyses had little effect on the estimates. Conclusions: This is the first randomised trial of the addition of resuscitative endovascular balloon occlusion of the aorta to standard care in the management of exsanguinating haemorrhage. All the analyses suggest that a strategy of standard care plus resuscitative endovascular balloon occlusion of the aorta is potentially harmful. Future work: The role (if any) of resuscitative endovascular balloon occlusion of the aorta in the pre-hospital setting remains unclear. Further research to clarify its potential (or not) may be required. Trial registration: This trial is registered as ISRCTN16184981. Funding: This award was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme (NIHR award ref: 14/199/09) and is published in full in Health Technology Assessment; Vol. 28, No. 54. See the NIHR Funding and Awards website for further award information.

Trauma (physical injury) is a major cause of death and disability. The most common cause of preventable death after injury is uncontrolled bleeding. Resuscitative endovascular balloon occlusion of the aorta is a technique whereby a small balloon is inflated in the aorta (main blood vessel) which aims to limit blood loss until an operation can be done to stop the bleeding. In this study, which is the first randomised trial in the world of this technique, we investigated whether adding resuscitative endovascular balloon occlusion of the aorta to the standard care received in a major trauma centre reduced the risk of death in trauma patients who had life-threatening uncontrolled bleeding. The study took place in 16 major trauma centres in the United Kingdom. Ninety adult trauma patients with confirmed or suspected uncontrolled bleeding took part and were randomly divided into two groups: (1) those who received standard care and (2) those who received standard care plus resuscitative endovascular balloon occlusion of the aorta. We followed participants for 6 months using routinely collected data from the National Health Service and from the Trauma Audit Research Network registry. We also contacted surviving patients at 6 months to ask about their quality of life. In the standard care group, 42% of participants died within 90 days of their injury compared to 54% of participants in the standard care plus resuscitative endovascular balloon occlusion of the aorta group. Risk of death was also higher in the standard care plus resuscitative endovascular balloon occlusion of the aorta group at all other time points (3, 6 and 24 hours, in hospital and at 6 months). Overall, the study showed that the use of resuscitative endovascular balloon occlusion of the aorta in hospital increased the risk of death.

Systematic analysis of the occurrence characteristics and impact on hospitalization costs of trauma complications.

BACKGROUND: Trauma complications increase the burden of disease and hospitalization costs for patients. More research evidence is needed on how to more effectively prevent these complications and reduce hospitalization costs based on the characteristics of trauma patients. Therefore, this study will systematically analyze the characteristics of trauma complications and their specific impact on hospitalization costs. METHODS: This is a multi-center retrospective study of trauma hospitalizations from 2018 to 2023. Associations between population characteristics, trauma features, and each complication occurrence were investigated using multiple correspondence analysis. Logistic regression analysis assessed factors influencing trauma complications. Additionally, a generalized linear model analyzed the relative increase in hospital costs for each complication. RESULTS: A total of 48,032 trauma patients were included, with 22.0% experiencing at least one complication. Thrombosis is more prevalent among elderly women (aged ≥65) with pelvic and extremity trauma. In men aged 18-44 years, respiratory insufficiency and post-traumatic anemia primarily occurred in cases of head injuries and multiple injuries. Chest and multiple injuries predispose people aged 45-64 to pneumonia and electrolyte disorders. Body surface injuries are prone to surgical site infections. Complications resulted in an average relative increase in overall hospitalization costs of 1.32-fold, with thrombosis (1.58-fold), respiratory insufficiency (1.11-fold), post-traumatic anemia (0.58-fold), surgical site infection (0.48-fold), pneumonia (0.53-fold), electrolyte disorders (0.47-fold). CONCLUSIONS: This study systematically analyzed the occurrence characteristics of trauma complications and the burden trends of hospitalization costs due to complications, providing a reference for the formulation of trauma classification and management strategies.

Cytomegalovirus Ileitis in a Patient With Post-severe Trauma: A Case Report.

BACKGROUND/AIM: The mortality rate for alimentary tract hemorrhage remains high due to a variety of contributing factors. In this report, we present a case of post-severe trauma patient with life-threatening gastrointestinal bleeding caused by cytomegalovirus (CMV)-induced damage to the terminal ileum. CASE REPORT: A 76-year-old female with a history of hypertension and gastrointestinal bleeding developed CMV ileitis post-severe trauma. Despite negative CMV IgM antibodies, PCR testing confirmed CMV infection in the biopsy tissue. Histopathological examination revealed viral inclusion bodies, with immunohistochemistry confirming CMV presence. RESULTS: Intravenous ganciclovir effectively managed symptoms and halted bleeding. CMV ileitis, typically seen in immunocompromised states, may occur sporadically in immunocompetent individuals, including post-orthopedic surgery patients. The exact mechanism remains unclear, possibly related to surgical stress. Diagnosis relies on histopathology and immunohistochemistry. CONCLUSION: Early recognition and treatment are vital for optimal outcomes, emphasizing the need for awareness among orthopedic surgeons regarding CMV as a potential cause of postoperative complications.

A dynamic online nomogram predicting post-traumatic arrhythmias: A retrospective cohort study.

BACKGROUND: A nomogram is a visualized clinical prediction models, which offer a scientific basis for clinical decision-making. There is a lack of reports on its use in predicting the risk of arrhythmias in trauma patients. This study aims to develop and validate a straightforward nomogram for predicting the risk of arrhythmias in trauma patients. METHODS: We retrospectively collected clinical data from 1119 acute trauma patients who were admitted to the Advanced Trauma Center of the Affiliated Hospital of Zunyi Medical University between January 2016 and May 2022. Data recorded included intra-hospital arrhythmia, ICU stay, and total hospitalization duration. Patients were classified into arrhythmia and non-arrhythmia groups. Data was summarized according to the occurrence and prognosis of post-traumatic arrhythmias, and randomly allocated into a training and validation sets at a ratio of 7:3. The nomogram was developed according to independent risk factors identified in the training set. Finally, the predictive performance of the nomogram model was validated. RESULTS: Arrhythmias were observed in 326 (29.1%) of the 1119 patients. Compared to the non-arrhythmia group, patients with arrhythmias had longer ICU and hospital stays and higher in-hospital mortality rates. Significant factors associated with post-traumatic arrhythmias included cardiovascular disease, catecholamine use, glasgow coma scale (GCS) score, abdominal abbreviated injury scale (AIS) score, injury severity score (ISS), blood glucose (GLU) levels, and international normalized ratio (INR). The area under the receiver operating characteristic curve (AUC) values for both the training and validation sets exceeded 0.7, indicating strong discriminatory power. The calibration curve showed good alignment between the predicted and actual probabilities of arrhythmias. Decision curve analysis (DCA) indicated a high net benefit for the model in predicting arrhythmias. The Hosmer-Lemeshow goodness-of-fit test confirmed the model's good fit. CONCLUSION: The nomogram developed in this study is a valuable tool for accurately predicting the risk of post-traumatic arrhythmias, offering a novel approach for physicians to tailor risk assessments to individual patients.

Construction of the discomfort assessment scale for immobilized trauma victims (DASITV).

BACKGROUND: Immobilization is an intervention widely administered to trauma victims and aims to reduce the victim's movements, ensuring the alignment of anatomical structures suspected of being injured. Despite the benefits of immobilization, it is responsible for the occurrence of pressure injuries, increases in intercranial pressure, pain, and discomfort. AIM: To develop an instrument to assess the discomfort caused by immobilization in trauma victims - Discomfort Assessment Scale for Immobilized Trauma Victims (DASITV). METHODS: A sequential mixed-methods design was used, divided into three distinct but complementary phases: (1) Conceptualization Phase - Construction of the DASITV; (2) Focus Group with a Panel of ten Technical Experts in the care of immobilized trauma victims to approve the DASITV proposal; (3) Acceptance of the scale proposal using a modified e-Delphi technique with 30 pre-hospital health professionals. RESULTS: The first phase led to the construction of a scale made up of two sub-scales. The Numerical Discomfort Scale assesses the level of discomfort the person reports from 0 to 10, with 0 being no discomfort and 10 being maximum discomfort. The second evaluation parameter gives the level of pressure in mmHg that the body exerts on the surface where it is immobilized. The combined interpretation of these two sub-scales leads to 4 different possibilities - ordered by level of severity. The Focus Group made it possible to improve the scale, with input from the group of experts and, using the modified e-Delphi technique, a wider group of professionals showed agreement with the DASITV. CONCLUSION: This study allowed us to propose a preliminary scale to assess the discomfort felt by victims of trauma caused by immobilization.

Prevalence and Patterns of Seizure-related Injuries: A Study of People Living with Epilepsy Found in a Community-based Door-to-door Survey in Southeast Nigeria.

CONTEXT: Epileptic seizures and the unpredictable falls resulting from epileptic seizures predispose the people living with epilepsy (PLWE) to various physical injuries as well as postictal cognitive and behavioral changes. AIMS: The aim of the study was to determine the frequency and patterns of seizure-related physical injuries, postictal cognitive impairments, and behavioral changes. SETTINGS AND DESIGN: This was a cross-sectional descriptive study in a Southeast Nigeria local government area. SUBJECTS AND METHODS: PLWE identified during a two-phase door-to-door survey and their caregivers were interviewed using a semi-structured questionnaire. STATISTICAL ANALYSIS USED: The Statistical Package for the Social Sciences version 22.0 was used. RESULTS: There were 56 cases of active convulsive seizures comprising 33 (58.9%) males and 23 (41.1%) females, with a mean age of 32.9 ± 14.2. The lifetime prevalence of seizure-related physical injuries, postictal behavioral changes, and postictal cognitive impairments was 9.8 per 1000 (95% confidence interval [CI]: 9.1-10.0), 8.4 per 1000 (95% CI: 7.2-9.2), and 6.3 per 1000 (95% CI: 4.9-7.5), respectively. Skin/soft-tissue injuries and tongue laceration were the most frequent physical injuries found in 66.1% ( n = 37/56) and 60.7% ( n = 34/56) of cases, respectively. The frequency of soft-tissue injuries was significantly higher (χ 2 = 5.038; P = 0.0248) in the females 78.3% ( n = 18/23) than the males 48.5% ( n = 16/33). About a third of the females 39.1% had burn injuries compared to 18.1% of the males. CONCLUSIONS: Seizure-related injuries are common and have the tendency to increase the burden of epilepsy and epilepsy-related stigma from deformities and the chronic disfiguring scars resulting from such injuries.

Trauma Patients and Acute Compartment Syndrome: Is There an Ariadne's Thread That Can Safely Guide the Anesthesiologist/Emergency Physician Out of the Labyrinth?

Trauma patients in the emergency department experience severe pain that is not always easy to manage. The risk of acute compartment syndrome further complicates the analgesic approach. The purpose of this review is to discuss relevant bibliography and highlight current guidelines and recommendations for the safe practice of peripheral nerve blocks in this special group of patients. According to the recent bibliography, peripheral nerve blocks are not contraindicated in patients at risk of acute compartment syndrome, as long as there is surveillance and certain recommendations are followed.

The impact of frailty on long-term functional outcomes in severely injured geriatric patients.

BACKGROUND: The incidence of severe injury in the geriatric population is increasing. However, the impact of frailty on long-term outcomes after injury in this population remains understudied. Therefore, we aimed to understand the impact of frailty on long-term functional outcomes of severely injured geriatric patients. METHODS: We conducted a retrospective cohort study, including patients ≥65 years old with an Injury Severity Score ≥15, who were admitted between December 2015 and April 2022 at one of 3 level 1 trauma centers in our region. Patients were contacted between 6 and 12 months postinjury and administered a trauma quality of life survey, which assessed for the presence of new functional limitations in their activities of daily living. We defined frailty using the mFI-5 validated frailty tool: patients with a score ≥2 out of 5 were considered frail. The impact of frailty on long-term functional outcomes was assessed using 1:1 propensity matching adjusting for patient characteristics, injury characteristics, and hospital site. RESULTS: We included 580 patients, of whom 146 (25.2%) were frail. In a propensity-matched sample of 125 pairs, frail patients reported significantly higher functional limitations than nonfrail patients (69.6% vs 47.2%; P < .001). This difference was most prominent in the following activities: climbing stairs, walking on flat surfaces, going to the bathroom, bathing, and cooking meals. In a subgroup analysis, frail patients with traumatic brain injuries experienced significantly higher long-term functional limitations. CONCLUSION: Frail geriatric patients with severe injury are more likely to have new long-term functional outcomes and may benefit from screening and postdischarge monitoring and rehabilitation services.

The Relationship Between Body Mass Index and Long-Term Outcomes Following Traumatic Injury.

INTRODUCTION: Little is known about the relationship between body mass index (BMI), a function of mass and height (masskg/height2m) and long-term outcomes among traumatic injury survivors. In this prospective cohort study, we investigate the relationship between BMI and long-term health outcomes in the trauma population. METHODS: Adult trauma survivors with an injury severity score ≥9 admitted to one of three level 1 trauma centers, from January 1, 2015 to December 31, 2022, were surveyed via telephone between 6 and 12 mo postinjury. Participants were stratified into one of five groups by BMI at the time of trauma: L-BMI (BMI <18.5), N-BMI (BMI 18.5-24.9), H1-BMI (BMI 25-29.9), H2-BMI (BMI 30-34.9), and H3-BMI (BMI ≥35); N-BMI was used as the referent. Mental and physical health-related quality of life scores, pain, new functional limitations, and hospital readmissions were evaluated. Univariate and multivariate analyses were used to compare outcomes between study groups. RESULTS: 3830 patients were included. Of those, 124 were L-BMI (3.2%), 1495 N-BMI (39%), 1318 H1-BMI (34.4%), 541 H2-BMI (14.1%), and 352 H3-BMI (9.2%). L-BMI was associated with adverse physical (b = -3.13, CI = -5.71 to -0.55, P = 0.017) and mental health (b = -3.17, CI = -5.87 to -0.46, P = 0.022) outcomes 6-12 mo postinjury compared to the referent. H1-BMI and H2-BMI had higher odds of wo`rse physical outcomes (b = -1.47, CI = -2.42 to -0.52, P = 0.002; b = -3.11, CI = - 4.33 to -1.88, P ≤ 0.001, respectively) and chronic pain (adjusted odds ratio (aOR) = 1.24, CI = 1.04-1.47, P = 0.016; aOR = 1.52, CI = 1.21-1.90, P ≤ 0.001, respectively). Patients with H3-BMI had higher odds of worse physical outcomes compared to N-BMI (b = -4.82, CI = -6.28 to -3.37, P ≤ 0.001), chronic pain (aOR = 2.11, CI = 1.61-2.78, P ≤ 0.001), all-cause hospital readmissions (aOR = 1.62, CI = 1.10-2.34, P = 0.013), and new functional limitations (aOR = 1.39, CI = 1.08-1.79, P = 0.01). CONCLUSIONS: BMI variance above or below N-BMI is associated with worse long-term outcomes following traumatic injury.

Association between clinical factors and mortality in older adult trauma patients: A systematic review and meta-analysis.

BACKGROUND: This study reviews and meta-analysis factors affecting mortality in older adult trauma patients, addressing previously unidentified heterogeneity and risk burden. METHODS: Databases (PubMed, Embase, Cochrane and Scopus) were searched for studies from January 1, 2000, to April 30, 2024. Inclusion criteria were patients aged ≥65 years with trauma, assessing survival or death outcomes. Two authors independently screened and extracted data using the PRISMA checklist; disagreements were resolved by a third author. RESULTS: Eighteen retrospective studies were included (425,355 patients), showing an overall mortality rate of 9.6 â€‹%. Falls were the predominant cause of injury. Demographic mortality risk factors included advanced age, frailty, male sex, and comorbidities (blood/bleeding disorders, liver disease, cancer, kidney disease, and lung disease). Injury risk factors were identified as contributing to the outcome, including low systolic blood pressure, Glasgow Coma Scale, Injury Severity Score, Revised Trauma Score, and surgical intervention. CONCLUSION: Trauma significantly elevates the mortality rate in older adults, with advanced age, gender, comorbidities, injury severity, frailty, and surgical intervention being key factors.

Fat embolism syndrome after trauma: What you need to know.

ABSTRACT: Fat embolism syndrome refers to a systemic condition caused by the circulation of fat droplets in the bloodstream, reaching various target organs typically after major bone fractures or related surgical procedures. Although most cases resolve spontaneously, severe instances can lead to significant respiratory failure, neurological damage, and even mortality. Therefore, appropriate prevention, timely diagnosis, and management are crucial for trauma patients at risk. The objective of this review article is to explore the definition, epidemiology, risk factors, clinical presentation, and pathophysiology of fat embolism syndrome. Furthermore, it aims to examine current recommendations for the accurate diagnosis, prevention, and treatment of it, providing a comprehensive guide for the effective management of patients prone to this condition.

Serum cortisol and neuroticism for post-traumatic stress disorder over 2 years in patients with physical injuries.

AIM: This study aimed to explore the relationships between serum cortisol levels, personality traits, and the development of Post-Traumatic Stress Disorder (PTSD) over 2 years among individuals with physical injuries. METHODS: Participants were consecutively recruited from a trauma center and followed prospectively for 2 years. At baseline, serum cortisol levels were measured, and personality traits were categorized into five dimensions (Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness), using the Big Five Inventory-10. The diagnosis of PTSD during follow-up (at 3, 6, 12, and 24 months post-injury) was determined using the Clinician-Administered PTSD Scale for DSM-5. Binary and multinomial logistic regression analyses were conducted to examine the interactions between cortisol levels, personality traits, and PTSD development. RESULTS: Among 923 patients analyzed, 112 (12.1%) were diagnosed with PTSD at some point during the study period, with prevalence rates decreasing from 8.8% at 3 months to 3.7% at 24 months post-injury. Direct associations between cortisol levels or personality traits and PTSD were not observed. However, a significant interaction between lower cortisol levels and higher Neuroticism in relation to PTSD risk was identified, especially during the early follow-up periods (3 to 6 months), but this association waned from the 12-month follow-up onward. CONCLUSION: Our findings reveal Neuroticism-dependent associations between serum cortisol levels and PTSD development, exhibiting temporal variations. These results suggest that PTSD development may be influenced by a complex, time-sensitive interplay of biological and psychosocial factors, underscoring the importance of considering individual differences in stress reactivity and personality in PTSD research and treatment.

Correction of Trauma-induced Coagulopathy by Goal-directed Therapy: A Secondary Analysis of the ITACTIC Trial.

BACKGROUND: Trauma hemorrhage induces a coagulopathy with a high associated mortality rate. The Implementing Treatment Algorithms for the Correction of Trauma Induced Coagulopathy (ITACTIC) randomized trial tested two goal-directed treatment algorithms for coagulation management: one guided by conventional coagulation tests and one by viscoelastic hemostatic assays (viscoelastic). The lack of a difference in 28-day mortality led the authors to hypothesize that coagulopathic patients received insufficient treatment to correct coagulopathy. METHODS: During ITACTIC, two sites were coenrolling patients into an ongoing prospective observational study, which included serial blood sampling at the same intervals as in ITACTIC. The subgroup in both studies had conventional and viscoelastic test results for each patient available for analysis. A goal-directed treatment was defined as one triggered by an ITACTIC algorithm. Coagulopathy was defined as rotational thromboelastometry EXTEM A5 less than 40 mm. The primary outcome was correction of coagulopathy by the 12th unit of erythrocyte transfusion during resuscitation. RESULTS: Full viscoelastic and conventional coagulation test results were available for 133 patients. Of these patients, 71% were coagulopathic on admission, and 16% developed a coagulopathy during resuscitation. ITACTIC viscoelastic hemostatic assay group patients were more likely to receive goal-directed treatment than the standard group (76% vs. 47%; odds ratio, 3.73; 95% CI, 1.64 to 8.49; P = 0.002). However, only 54% of patients received goal-directed treatment, and only 20% corrected their coagulopathy (vs. 0% with empiric treatment alone; not significant). Median time to first goal-directed treatment was 68 (53 to 88) min for viscoelastic and 110 (77 to 123) min for standard (P = 0.005). CONCLUSIONS: In ITACTIC, many bleeding trauma patients did not receive an indicated goal-directed treatment. Interventions arrived late during resuscitation and were only partially effective at correcting coagulopathy.
