RESUMO

Background and Purpose: Vulnerable populations are social groups at increased risk for poor health outcomes. According to the vulnerable populations conceptual model (VPCM) nursing theory, vulnerable groups such as survivors of intimate partner violence (IPV) are at risk for disease, morbidity, and mortality due to limited resources. The purpose of this article is to propose the VPCM as an organizing theoretical framework in the acute care setting of trauma patients suffering from IPV by outlining the factors affecting the care of this vulnerable population. Results: This synthesis of the literature outlines the decreased resource availability and increased relative risk encountered by IPV survivors, which results in poor health, which supports the application of the VPCM as a guiding theory. The VPCM provides a structure for understanding IPV patients and equips nursing with a framework for taking action through engagement, assessment, intervention, and evaluation of practice when caring for this vulnerable trauma population in the acute care setting. Implications for Practice: Using a theory-based model provides a framework for clinical practice interventions. Further research in the application of the VPCM as a theoretical basis for caring for trauma patients who are survivors of IPV is needed.

RESUMO

In recent years, with the deepening of researches on the molecular biological mechanisms of photobiomodulation (PBM), PBM has gradually been applied in clinical practice, providing effective treatment methods and approaches for various diseases. Compared with traditional photothermal therapy, PBM has the characteristics of good therapeutic effect, almost no adverse reaction, and simple operation, and its clinical efficacy is becoming increasingly significant. This article provides a detailed explanation on the mechanism of PBM, its application characteristics and development trends in trauma repair and medical aesthetics, in order to provide a theoretical basis for the extensively clinical application of this therapy.

RESUMO

BACKGROUND: Increasing mountain activity and decreasing participant preparedness, as well as climate change, suggest needs to tailor mountain rescue. In Sweden, previous medical research of these services are lacking. The aim of the study is to describe Swedish mountain rescue missions as a basis for future studies, public education, resource allocation, and rescuer training. METHODS: Retrospective analysis of all mission reports in the national Swedish Police Registry on Mountain Rescue 2018-2022 (n = 1543). Outcome measures were frequencies and characteristics of missions, casualties, fatalities, traumatic injuries, medical conditions, and incident mechanisms. RESULTS: Jämtland county had the highest proportion of missions (38%), followed by Norrbotten county (36%). 2% of missions involved ≥ 4 casualties, and 44% involved ≥ 4 mountain rescuers. Helicopter use was recorded in 59% of missions. Non-Swedish citizens were rescued in 12% of missions. 37% of casualties were females. 14% of casualties were ≥ 66 or ≤ 12 years of age. Of a total 39 fatalities, cardiac event (n = 14) was the most frequent cause of death, followed by trauma (n = 10) and drowning (n = 8). There was one avalanche fatality. 8 fatalities were related to snowmobiling, and of the total 1543 missions, 309 (20%) were addressing snowmobiling incidents. Of non-fatal casualties, 431 involved a medical condition, of which 90 (21%) suffered hypothermia and 73 (17%) cardiovascular illness. CONCLUSIONS: These baseline data suggest snowmobiling, cardiac events, drownings, multi-casualty incidents, and backcountry internal medicine merit future study and intervention.

RESUMO

INTRODUCTION: Hemorrhage is a major cause of preventable trauma deaths, and the ABC approach is widely used during the primary survey. We hypothesize that prioritizing circulation over intubation (CAB) can improve outcomes in patients with exsanguinating injuries. METHODS: A prospective observational study involving international trauma centers was conducted. Patients with systolic blood pressure below 90 who were intubated within 30 min of arrival were included. Prioritizing circulation (CAB) was defined as delaying intubation until blood products were started, and/or bleeding control was performed before securing the airway. Demographics, clinical data, and outcomes were recorded. RESULTS: The study included 278 eligible patients, with 61.5% falling within the "CAB" cohort and 38.5% in the "ABC" cohort. Demographic and disease characteristics, including age, sex, ISS, use of blood products, and other relevant factors, exhibited comparable distributions between the two cohorts. The CAB group had a higher proportion of penetrating injuries and more patients receiving intubation in the operating room. Notably, patients in the CAB group demonstrated higher GCS scores, lower SBP values before intubation but higher after intubation, and a significantly lower incidence of cardiac arrest and post-intubation hypotension. Key outcomes revealed significantly lower 24-hour mortality in the CAB group (11.1% vs. 69.2%), a lower rate of renal failure, and a higher rate of ARDS. Multivariable logistic regression models showed a 91% reduction in the odds of mortality within 24 h and an 89% reduction at 30 days for the CAB cohort compared to the ABC cohort. These findings suggest that prioritizing circulation before intubation is associated with improved outcomes in patients with exsanguinating injuries. CONCLUSION: Post-intubation hypotension is observed to be correlated with worse outcomes. The consideration of prioritizing circulation over intubation in patients with exsanguinating injuries, allowing for resuscitation, or bleeding control, appears to be associated with potential improvements in survival. Emphasizing the importance of circulation and resuscitation is crucial, and this approach might offer benefits for various bleeding-related conditions.

RESUMO

Road crashes are a major public safety concern in Pakistan. Prior studies in Pakistan investigated the impact of different factors on road crashes but did not consider the temporal stability of crash data. This means that the recommendations based on these studies are not fully effective, as the impact of certain factors may change over time. To address this gap in the literature, this study aims to identify the factors contributing to crash severity in road crashes and examine how their impact varies over time. In this comprehensive study, we utilized Generalised Linear Model (GLM) on the crash data between the years 2013 to 2017, encompassing a total sample of 802 road crashes occurred on the N-5 road section in Pakistan, a 429-kilometer stretch connecting two big cities of Pakistan, i.e., Peshawar and Lahore. The purpose of the GLM was to quantify the temporal stability of the factors contributing crash severity in each year from 2013 to 2017. Within this dataset, 60% (n = 471) were fatal crashes, while the remaining 40% (n = 321) were non-fatal. The results revealed that the factors including the day of the week, the location of the crashes, weather conditions, causes of the crashes, and the types of vehicles involved, exhibited the temporal instability over time. In summary, our study provides in-depth insights aimed at reducing crash severity and potentially aiding in the development of effective crash mitigation policies in Pakistan and other nations having similar road safety problems. This research holds great promise in exploring the dynamic safety implications of emerging transportation technologies, particularly in the context of the widespread adoption of connected and autonomous vehicles.

RESUMO

Recently, resuscitative endovascular balloon occlusion of the aorta (REBOA) had been introduced as an innovative procedure for severe hemorrhage in the abdomen or pelvis. We aimed to investigate risk factors associated with mortality after REBOA and construct a model for predicting mortality. This multicenter retrospective study collected data from 251 patients admitted at five regional trauma centers across South Korea from 2015 to 2022. The indications for REBOA included patients experiencing hypovolemic shock due to hemorrhage in the abdomen, pelvis, or lower extremities, and those who were non-responders (systolic blood pressure (SBP) < 90 mmHg) to initial fluid treatment. The primary and secondary outcomes were mortality due to exsanguination and overall mortality, respectively. After feature selection using the least absolute shrinkage and selection operator (LASSO) logistic regression model to minimize overfitting, a multivariate logistic regression (MLR) model and nomogram were constructed. In the MLR model using risk factors selected in the LASSO, five risk factors, including initial heart rate (adjusted odds ratio [aOR], 0.99; 95% confidence interval [CI], 0.98-1.00; p = 0.030), initial Glasgow coma scale (aOR, 0.86; 95% CI 0.80-0.93; p < 0.001), RBC transfusion within 4 h (unit, aOR, 1.12; 95% CI 1.07-1.17; p < 0.001), balloon occlusion type (reference: partial occlusion; total occlusion, aOR, 2.53; 95% CI 1.27-5.02; p = 0.008; partial + total occlusion, aOR, 2.04; 95% CI 0.71-5.86; p = 0.187), and post-REBOA systolic blood pressure (SBP) (aOR, 0.98; 95% CI 0.97-0.99; p < 0.001) were significantly associated with mortality due to exsanguination. The prediction model showed an area under curve, sensitivity, and specificity of 0.855, 73.2%, and 83.6%, respectively. Decision curve analysis showed that the predictive model had increased net benefits across a wide range of threshold probabilities. This study developed a novel intuitive nomogram for predicting mortality in patients undergoing REBOA. Our proposed model exhibited excellent performance and revealed that total occlusion was associated with poor outcomes, with post-REBOA SBP potentially being an effective surrogate measure.

RESUMO

In this special communication, an overview of the research on trauma, resilience, and action items for the pediatric physical therapist (PT) is addressed. The experiences of early childhood, positive and negative, impact overall development and well-being throughout the lifespan. Childhood trauma can include exposure to abuse, neglect, violence, racism, or medical procedures. These adverse childhood experiences are associated with poor physical and mental health outcomes that can extend into adulthood and can appear in the pediatric rehabilitative realm as caregivers who become labeled noncompliant. Trauma is common and impacts all children; however, some populations, such as children with disabilities, have greater risk for experiencing adversity. An individual's trauma history is not always visible, necessitating a standard approach. Pediatric PTs must take an intentional approach to address the detrimental effects of trauma on those we serve. Many organizations recommend adopting trauma-informed care as the standard of care for all populations.

RESUMO

OBJECTIVE: Road traffic crashes cause 1.19 million deaths and millions more injuries annually. The persistently high burden has drawn attention from national and international stakeholders worldwide. Unsafe road infrastructure is one of the major risk factors for traffic safety, particularly in low- and middle-income countries. METHODS: Aiming to eliminate high-risk roads in all countries, the International Road Assessment Programme (iRAP) developed a robust and evidence-based approach to support country transportation agencies. RESULTS: Thus far, the iRAP protocols have been used to collect 1.8 million kilometers of Crash Risk Mapping and 1.5 million kilometers of Star Rating and FSI estimations in 128 countries. Deploying an observational before-and-after (or pre-post) study design, this report estimated the fatal and series injuries (FSI) saved through use of the iRAP protocols. The study is based on 441,753 kilometers of assessed roads from 1,039 projects in 74 countries. Our results show that the implementation of iRAP's proposed countermeasures saves about 159,936 FSI annually. Throughout the lifetime of the implemented countermeasures, a total of 3.2 million FSI could be saved. CONCLUSION: While quantifying the success of the iRAP protocols, our results suggest an opportunity to save many millions more lives on the roads through expanding iRAP implementation to more regions and countries.

RESUMO

Introduction: Globally, injuries pose significant public health challenges, with road traffic accidents in particular being responsible for considerable morbidity, mortality, and economic distress. Italy has been significantly impacted due to its high population density and frequency of road traffic and domestic incidents. Method: This study set out to investigate the incidence of self-reported road traffic and home and leisure accidents in the Italian general population. A particular emphasis was placed on exploring possible gender differences across varying age groups. The data was obtained from the European Health Interview Survey and a representative sample of the Italian population was analyzed. Results: The analysis revealed that regardless of age, women experienced a reduced risk of road traffic accidents compared to men. However, gender disparities in home-leisure accidents were observed to be age-dependent. Women under the age of 25 exhibited a lower likelihood of home-leisure accidents and serious accidents necessitating hospital admission in comparison to their male counterparts. In contrast, women aged 65 and above had an increased likelihood of home-leisure accidents as opposed to men in the same age category. Conclusions: The findings of this study highlight the importance of considering age and gender as significant factors in the occurrence of different types of accidents, offering insight into how injury rates vary between these demographic groups within Italy.

RESUMO

OBJECTIVE: This study examined changes in wound symptoms and the health-related quality of life (HRQoL) of patients with newly diagnosed malignant fungating wounds, and explored the factors that impacted the changes in HRQoL. METHOD: This prospective longitudinal study included patients from three hospitals in China who had been diagnosed with malignant fungating wounds. Questionnaires were used to assess patients' HRQoL and their wound symptoms at the time of diagnosis (T0), as well as at one, three and six (T1, T2 and T3, respectively) months following the treatment period. Factors related to changes in HRQoL were analysed using generalised estimating equation models. RESULTS: A total of 162 patients were included in the study. The patients reported low overall HRQoL. In three health-related dimensions (functional status, social relations and mental health), patients reported lower functional status at the time of wound diagnosis (T0), which then increased slowly with treatment over time. A lower QoL was associated with odour, exudate, bleeding, pruritus, a low performance status and the need for the dressing of wounds. CONCLUSION: The HRQoL of patients with malignant fungating wounds exhibited significant changes across different periods. It is thus of great importance to formulate pragmatic, patient and family-centred palliative wound care management strategies.

RESUMO

Refractory wounds present complex and serious clinical dilemmas in plastic and reconstructive surgeries. Currently, there are no standard guidelines for the treatment of refractory wounds. To observe the clinical effects of ultraviolet (UV) therapy combined with autologous platelet-rich plasma (PRP) on chronic refractory wounds. Between January 2021 and December 2022, 60 inpatients with chronic refractory wounds were enrolled. Twenty patients were assigned to each of control groups 1 and 2 and treatment group according to whether they received PRP or UV treatment. All the patients underwent thorough debridement. Control group 2 received UV radiation. The treatment group underwent UV radiation combined with PRP gel covering the wound. Control group 1 underwent routine dressing changes after surgery, followed by skin grafting or skin key transfer if needed. One month later, we observed the wound healing in the two groups. After 2-4 PRP gel treatments, the wounds of patients in the treatment group healed. The healing time was 25.25 ± 4.93 days, and the dressings were changed 4.15 ± 3.30 times, both of which were better outcomes than in both control groups. In the treatment group, epidermal growth factor (EGF), insulin-like growth factor (IGF), platelet-derived growth factor (PGF), and transforming growth factor ß (TGF-ß) were slightly higher, and the concentration of vascular endothelial growth factor (VEGF) was significantly higher than in the control group (p < 0.05). PRP combined with UV therapy significantly increased the concentration of wound growth factors, accelerated wound healing, shortened treatment time, reduced treatment costs, and alleviated pain in patients.

RESUMO

BACKGROUND: Identifying patients at imminent risk of death is critical in the management of trauma patients. This study measures the vital sign thresholds associated with death among trauma patients. METHODS: This study included data from patients ≥15 years of age in the American College of Surgeons Trauma Quality Improvement Program (TQIP) database. Patients with vital signs of zero were excluded. Documented prehospital and emergency department (ED) vital signs included systolic pressure, heart rate, respiratory rate, and calculated shock index (SI). The area under the receiver operator curves (AUROC) was used to assess the accuracy of these variables for predicting 24-hour survival. Optimal thresholds to predict mortality were identified using Youden's Index, 90% specificity, and 90% sensitivity. Additional analyses examined patients 70+ years of age. RESULTS: There were 1,439,221 subjects in the 2019-2020 datasets that met inclusion for this analysis with <0.1% (10,270) who died within 24 hours. The optimal threshold for prehospital systolic pressure was 110, pulse rate was 110, SI was 0.9, and respiratory rate was 15. The optimal threshold for the ED systolic was 112, pulse rate was 107, SI was 0.9, and respiratory rate was 21. Among the elderly sub-analysis, the optimal threshold for prehospital systolic was 116, pulse rate was 100, SI was 0.8, and respiratory rate was 21. The optimal threshold for ED systolic was 121, pulse rate was 95, SI was 0.8, and respiratory rate was 0.8. CONCLUSIONS: Systolic blood pressure (SBP) and SI offered the best predictor of mortality among trauma patients. The SBP values predictive of mortality were significantly higher than the traditional 90mmHg threshold. This dataset highlights the need for better methods to guide resuscitation as initial vital signs have limited accuracy in predicting subsequent mortality.

RESUMO

Hereby, we aimed to comprehensively compare different scoring systems for pediatric trauma and their ability to predict in-hospital mortality and intensive care unit (ICU) admission. The current registry-based multicenter study encompassed a comprehensive dataset of 6709 pediatric trauma patients aged ≤ 18 years from July 2016 to September 2023. To ascertain the predictive efficacy of the scoring systems, the area under the receiver operating characteristic curve (AUC) was calculated. A total of 720 individuals (10.7%) required admission to the ICU. The mortality rate was 1.1% (n = 72). The most predictive scoring system for in-hospital mortality was the adjusted trauma and injury severity score (aTRISS) (AUC = 0.982), followed by trauma and injury severity score (TRISS) (AUC = 0.980), new trauma and injury severity score (NTRISS) (AUC = 0.972), Glasgow coma scale (GCS) (AUC = 0.9546), revised trauma score (RTS) (AUC = 0.944), pre-hospital index (PHI) (AUC = 0.936), injury severity score (ISS) (AUC = 0.901), new injury severity score (NISS) (AUC = 0.900), and abbreviated injury scale (AIS) (AUC = 0.734). Given the predictive performance of the scoring systems for ICU admission, NTRISS had the highest predictive performance (AUC = 0.837), followed by aTRISS (AUC = 0.836), TRISS (AUC = 0.823), ISS (AUC = 0.807), NISS (AUC = 0.805), GCS (AUC = 0.735), RTS (AUC = 0.698), PHI (AUC = 0.662), and AIS (AUC = 0.651). In the present study, we concluded the superiority of the TRISS and its two derived counterparts, aTRISS and NTRISS, compared to other scoring systems, to efficiently discerning individuals who possess a heightened susceptibility to unfavorable consequences. The significance of these findings underscores the necessity of incorporating these metrics into the realm of clinical practice.

RESUMO

OBJECTIVE: Large passenger vehicles have consistently demonstrated an outsized injury risk to pedestrians they strike, particularly those with tall, blunt front ends. However, the specific injuries suffered by pedestrians in these crashes as well as the mechanics of those injuries remain unclear. The current study was conducted to explore how a variety of vehicle measurements affect pedestrian injury outcomes using crash reconstruction and detailed injury attribution. METHODS: We analyzed 121 pedestrian crashes together with a set of vehicle measurements for each crash: hood leading edge height, bumper lead angle, hood length, hood angle, and windshield angle. RESULTS: Consistent with past research, having a higher hood leading edge height increased pedestrian injury severity, especially among vehicles with blunt front ends. The poor crash outcomes associated with these vehicles stem from greater injury risk and severity to the torso and hip from these vehicles' front ends and a tendency for them to throw pedestrians forward after impact. CONCLUSIONS: The combination of vehicle height and a steep bumper lead angle may explain the elevated pedestrian crash severity typically observed among large vehicles.

RESUMO

Despite advances in the treatment and care of severe physical injuries, trauma remains one of the main reasons for disability-adjusted life years worldwide. Trauma patients often suffer from disturbances in energy utilization and metabolic dysfunction, including hyperglycemia and increased insulin resistance. White adipose tissue plays an essential role in the regulation of energy homeostasis and is frequently implicated in traumatic injury due to its ubiquitous body distribution but remains poorly studied. Initial triggers of the trauma response are mainly damage-associated molecular patterns (DAMPs) such as histones. We hypothesized that DAMP-induced adipose tissue inflammation contributes to metabolic dysfunction in trauma patients. Therefore, we investigated whether histone release during traumatic injury affects adipose tissue. Making use of a murine polytrauma model with hemorrhagic shock, we found increased serum levels of histones accompanied by an inflammatory response in white adipose tissue. In vitro, extracellular histones induced an inflammatory response in human adipocytes. On the molecular level, this inflammatory response was mediated via a MYD88-IRAK1-ERK signaling axis as demonstrated by pharmacological and genetic inhibition. Histones also induced lytic cell death executed independently of caspases and RIPK1 activity. Importantly, we detected increased histone levels in the bloodstream of patients after polytrauma. Such patients might benefit from a therapy consisting of activated protein C and the FDA-approved ERK inhibitor trametinib, as this combination effectively prevented histone-mediated effects on both, inflammatory gene activation and cell death in adipocytes. Preventing adipose tissue inflammation and adipocyte death in patients with polytrauma could help minimize posttraumatic metabolic dysfunction.

RESUMO

BACKGROUND: Early identification of patients at risk of potential death and timely transfer to appropriate healthcare facilities are critical for reducing the number of preventable trauma deaths. This study aimed to establish a cutoff value to predict in-hospital mortality using the reverse shock index multiplied by the Glasgow Coma Scale (rSIG). METHODS: This multicenter retrospective cohort study used data from 23 emergency departments in South Korea between January 2011 and December 2020. The outcome variable was the in-hospital mortality. The relationship between rSIG and in-hospital mortality was plotted using the shape-restricted regression spline method. To set a cutoff for rSIG, we found the point on the curve where mortality started to increase and the point where the slope of the mortality curve changed the most. We also calculated the cutoff value for rSIG using Youden's index. RESULTS: A total of 318,506 adult patients with trauma were included. The shape-restricted regression spline curve showed that in-hospital mortality began to increase when the rSIG value was less than 18.86, and the slope of the graph increased the most at 12.57. The cutoff of 16.5, calculated using Youden's index, was closest to the target under-triage and over-triage rates, as suggested by the American College of Surgeons, when applied to patients with an rSIG of 20 or less. In addition, in patients with traumatic brain injury, when the rSIG value was over 25, in-hospital mortality tended to increase as the rSIG value increased. CONCLUSIONS: We propose an rSIG cutoff value of 16.5 as a predictor of in-hospital mortality in adult patients with trauma. However, in patients with traumatic brain injury, a high rSIG is also associated with in-hospital mortality. Appropriate cutoffs should be established for this group in the future.
