Finite element analysis of a novel anatomical plate in posterolateral plateau fractures.

This study aims to analyze the biomechanical characteristics of posterolateral plateau fractures fixed by a novel anatomical plate using finite element analysis. A three-dimensional digital model of the full length of right tibiofibula was obtained by CT scanning. A posterolateral tibial plateau fracture model was then created. The acquired fracture model was assembled with 4 groups of internal fixations: Group A, novel anatomical plate; Group B, straight buttress plate; Group C, oblique T-shaped locking plate; Group D, two lag screws. Axial loads of 500, 1,000 and 1,500 N perpendicular to the horizontal plane were used to simulate the stress on the lateral plateau of a 65 kg person standing, walking and fast running. Vertical displacements of the posterolateral fragments in each of the four groups gradually increased under loads from 500 N to 1,500 N. The maximum displacement of the fracture fragment in four groups were all located on the lateral side of the proximal part, and the displacement gradually decreased from the proximal part to the distal end. The maximum displacement values under the axial load of 1,500 N was in the following order: novel anatomical plate (1.2365 mm) < oblique T-shaped locking plate (1.314 mm) < two lag screws (1.3747 mm) < straight buttress plate (1.3932 mm). As the axial load increased, the stress value of the different internal fixation models gradually increased. The stress behavior of the same internal fixation model under different loads was similar. The maximum stress value under the axial load of 1,500 N was in the following order: novel anatomical plate (114.63 MPa) < oblique T-shaped locking plate (277.17 MPa) < two lag screws (236.75 MPa) < straight buttress plate (136.2 MPa). The patients with posterolateral plateau fractures fixed with a novel anatomical plate in standing, walking and fast running can achieve satisfactory biomechanical results, which lays the foundation for future applications. At the same time, clinical fracture types are often diverse and accompanied by damage to the soft tissue. Therefore, the ideal surgical approach and appropriate internal fixation must be selected based on the patient's injury condition.

Virtual reality gameplay classification illustrates the multidimensionality of visuospatial neglect.

Brain injuries can significantly impact mental processes and lead to hidden disabilities not easily detectable. Traditional methods for assessing these impacts are imprecise, leading to unreliable prevalence estimates and treatments with uncertain effectiveness. Immersive virtual reality has shown promise for assessment, but its use as a standalone tool is rare. Our research focused on developing and validating a standalone immersive virtual reality classification system for unilateral spatial neglect, a condition common following brain injury characterized by inattention to one side of space. Our study involved 51 brain injury inpatients and 30 controls, all engaging with 'The Attention Atlas', an immersive virtual reality game for testing visual search skills. Our classification system aimed to identify patients with neglect, 'minor atypicality' (indicative of inattention not consistent enough to be labelled as neglect) or non-neglect. This categorization was based on a simple mathematical definition, utilizing gameplay to describe spatial orientation (to the left or right side) and attentional challenge (indicative of search inefficiency). These metrics were benchmarked against a normative model to detect atypical visual search, which refers to gameplay beyond the usual bounds. The combination of neglected side, orientation and challenge factors was used to categorize neglect. We discovered a strong correlation between atypical visual search patterns and neglect risk factors, such as middle cerebral artery stroke, parietal injuries and existing neglect diagnoses (Poisson regression incidence rate ratio = 7.18, 95% confidence interval = 4.41-11.90). In our study, immersive virtual reality-identified neglect in one-fourth of the patients (n = 13, 25.5%), minor atypicality in 17.6% (n = 9) and non-neglect in the majority, 56.9% (n = 29). This contrasts with standard assessments, which detected neglect in 17.6% (n = 9) of cases and had no intermediate category. Our analysis determined six categories of neglect, the most common being left hemispace neglect with above-median orientation and challenge scores. Traditional assessments were not significantly more accurate (accuracy = 84.3%, P = 0.06) than a blanket assumption of non-neglect. Traditional assessments were also relatively insensitive in detecting immersive virtual reality-identified neglect (53.8%), particularly in less severe cases and those involving right-side inattention. Our findings underline the effectiveness of immersive virtual reality in revealing various dimensions of neglect, surpassing traditional methods in sensitivity and detail and operating independently from them. To integrate immersive virtual reality into real-world clinical settings, collaboration with healthcare professionals, patients and other stakeholders is crucial to ensure practical applicability and accessibility.

Shock Index and Lactate Level as Prognostic Factors of 24-Hour Mortality in Polytraumatized Patients in Emergency Services

Trauma is third in the world in terms of causes of mortality, accounting for 10% of all deaths. It is the primary cause of mortality for most persons under 40 and leads to severe disabilities. In addition, an increasing proportion of senior trauma patients are at increased risk of mortality. Hemorrhage is one of the two main causes of mortality after trauma, with 80% of deaths occurring within 48 hours. As a result, early, individualized treatment and proper triage are critical components of the trauma system, matching resources to the severity of the patient's injuries without overburdening the system. Whether to send a patient to a trauma center is the first choice made during triage 1-4.

Cold burn injuries in the United Kingdom: A five-year cohort study of patients presenting to a regional burn unit

AimsTo assess the aetiology, management and outcomes of cold burn injuries presenting to a regional burn unit in the United Kingdom. MethodsRetrospective cohort study of consecutive patients over a five-year period (2018-22). ResultsSixty-two patients (M:F 34:38; median age 23.5 years) were identified. The most common aetiology was aerosol (n=28, 45.2%). Seven (11.5%) injuries were sustained during a social media or peer ‘challenge’ and nineteen (31.2%) were self-harm, of whom five (26.3%) were inpatients on a mental health ward at the time of injury. All ‘challenge’ and self-harm injuries were caused by aerosol. ‘Challenge’ injury patients were younger than those with self-harm (p=.007) and non-intentional injuries (p<.001). A greater proportion of self-harm injuries were in female patients compared to non-intentional injuries (p<.001). Median TBSA was 0.35% (IQR 0.3). Most burns were superficial partial-thickness (n=35, 56.5%), followed by deep-dermal (n=18, 29.0%), full-thickness (n=8, 12.9%), and superficial (n=1, 1.6%). The upper limb was most frequently affected (n=35, 56.5%). Aetiology and whether a non-intentional, ‘challenge’ or self-harm injury did not affect TBSA (p=0.776 & p=0.364) or depth (p=0.353 & p=0.381). Five (8.1%) patients underwent autografting. The median time to healing was 17 days (range 7-45, IQR 22.75). Follow-up ranged from 1-173 weeks. ConclusionsThe incidence of cold burns has increased when compared with previous literature. A disproportionate number of cold burns are self-inflicted using aerosols, either as self-harm or due to social media or peer ‘challenges’. Other emerging aetiologies include non-intentional skin contact with nitrous oxide containers during its recreational use.

Management and Outcomes of Traumatic Liver Injury: A Retrospective Analysis from a Tertiary Care Center Experience.

although liver injuries are one of the most critical complications of abdominal trauma, choosing when to operate on these injuries is challenging for surgeons worldwide. We conducted a retrospective analysis of liver injury cases at our institution from 2016 to 2022 to describe the operative and nonoperative management (NOM) outcomes in patients with traumatic liver injuries. Baseline patient characteristics, liver injury details, treatments, and outcomes were analyzed. Data from 45 patients (male, 77.8%) were analyzed. The mean age was 29.3 years. Blunt trauma was the most common injury mechanism (86.7%), whereas penetrating injuries were 8.9% of cases. Conservative management was associated with 18.9% of complications. The overall complication rate was 26.7%; delirium and sepsis were the most common (13.3%), followed by acute renal failure (4.4%), pneumonia, biliary leaks, and meningitis/seizures. Notwithstanding its limitations, this retrospective analysis demonstrated that NOM can serve as a safe and effective strategy for hemodynamically stable patients with liver trauma, irrespective of the patient's injury grade. Nevertheless, careful patient selection and monitoring are crucial. Further investigations are necessary to thoroughly evaluate the management of traumatic liver injuries, particularly in the context of multiorgan injuries.

Alcohol use among emergency medicine department patients in Tanzania: A comparative analysis of injury versus non-injury patients.

Alcohol is a leading behavioral risk factor for death and disability worldwide. Tanzania has few trained personnel and resources for treating unhealthy alcohol use. In Emergency Medicine Departments (EMDs), alcohol is a well-known risk factor for injury patients. At Kilimanjaro Christian Medical Center (KCMC) in Moshi, Tanzania, 30% of EMD injury patients (IP) test positive for alcohol upon arrival to the ED. While the IP population is prime for EMD-based interventions, there is limited data on if non-injury patients (NIP) have similar alcohol use behavior and potentially benefit from screening and intervention as well. This was a secondary analysis of a systematic random sampling of adult (≥18 years old), KiSwahili speaking, KCMC EMD patients surveyed between October 2021 and May 2022. When medically stable and clinically sober, participants provided informed consent. Information on demographics (sex, age, years of education, type of employment, income, marital status, tribe, and religion), injury status, self-reported alcohol use, and Alcohol Use Disorder (AUD) Identification Test (AUDIT) scores were collected. Descriptive statistics were analyzed in RStudio using frequencies and proportions. Of the 376 patients enrolled, 59 (15.7%) presented with an injury. The IP and NIP groups did not differ in any demographics except sex, an expected difference as females were intentionally oversampled in the original study design. The mean [SD] AUDIT score (IP: 5.8 [6.6]; NIP: 3.9 [6.1]), drinks per week, and proportion of AUDIT ≥8 was higher for IP (IP:37%; NIP: 21%). However, alcohol preferences, drinking quantity, weekly expenditure on alcohol, perceptions of unhealthy alcohol use, attempts and reasons to quit, and treatment seeking were comparable between IPs and NIPs. Our data suggests 37% of injury and 20% of non-injury patients screen positive for harmful or hazardous drinking in our setting. An EMD-based alcohol treatment and referral process could be beneficial to reduce this growing behavioral risk factor in non-injury as well as injury populations.

Comprehensive Medical History Interview: Practical Guidance

Abstract Independent medical evaluations (IMEs), impairment assessments, and providing clinical care mandate obtaining an appropriate history. The medical interview is a crucial component for obtaining an accurate and complete medical history for IMEs, which requires interpersonal and analytical skills. The interview is a purposeful conversation aimed at understanding the patient's experiences, with a focus on verbal and nonverbal cues, to help build a comprehensive understanding of the patient's injury and current problems within the context of their overall health. The extent of history that is documented depends on the purpose of the evaluation and the nature of the injury. The process involves documenting chief complaints, injury details, pre-existing conditions, clinical course, current symptoms, and functional and past medical history.

Rehabilitation of Older Asian Traumatic Brain Injury Inpatients: A Retrospective Study Comparing Functional Independence between Age Groups.

Across traumatic brain injury (TBI) severities, a geriatric TBI tsunami has emerged. Mixed outcomes are reported for elderly TBI with positive functional improvements with acute inpatient rehabilitation. We studied the effect of age at TBI on discharge functional outcomes, levels of independence and length of stay. A retrospective analysis of Asian TBI patients during inpatient rehabilitation over a 4-year period was conducted. Independent variables included admission GCS, post-traumatic amnesia (PTA) duration and injury subtypes. Primary outcomes were discharge Functional Independence Measure (Td-FIM) and FIM gain. In total, 203 datasets were analysed; 60.1% (122) were aged ≥65 years (older), while 39.9% (81) were <65 years (younger). At discharge, older TBI had a significantly lower Td-FIM by 15 points compared to younger (older 90/126 vs. younger 105/126, p < 0.001). Median FIM gains (younger 27 vs. older 23, p = 0.83) and rehabilitation LOS (older 29.5 days vs. younger 27.5 days, p = 0.79) were similar for both age groups. Older TBIs had significantly lower independence (Td-FIM category ≥ 91) levels (49.4% older vs. 63.9% younger, p = 0.04), higher institutionalisation rates (23.5% older vs. 10.7% younger, p = 0.014) and need for carers (81.5% older vs. 66.4% younger, p = 0.019) on discharge. Although 77% of older TBI patients returned home, a significantly higher proportion needed care. This study supports the functional benefits of TBI rehabilitation in increasing independence regardless of age without incurring longer inpatient rehabilitation days.

Inhalational Injury Secondary to House Fire.

This scenario was developed to educate emergency medicine residents on the diagnosis and management of patients with an inhalational airway injury secondary to a house fire. Burn injuries are a common occurrence encountered by the emergency physician. According to the National Hospital Ambulatory Medical Care Survey, around 371,000 patients were treated in emergency departments for fire or burn injuries across the United States in 2020. This represents around 1% of emergency department visits related to injury, poisoning, or adverse effects.1 One of the most dangerous and time critical aspects of managing severely burned patients is inhalation injury. Inhalation injury is a relatively vague term which may refer to pulmonary exposure to a wide range of chemicals in various forms. In the context of burn patients, this is most often smoke exposure. It is critical that the emergency medicine provider rapidly identifies the potential for an inhalational injury in order to determine the need for definitive airway management. It is also important that the provider has the necessary skills and systematic approach to manage what is likely to be a difficult airway. Furthermore, providers must then have the knowledge of how to best manage and resuscitate these severely burned patients post-intubation. At the conclusion of the simulation session, learners will be able to: 1) recognize the indications for intubation in a thermal burn/inhalation injury patient; 2) develop a systematic approach to an inhalational injury airway; and 3) recognize indications for transfer to burn center. This session was conducted using high-fidelity simulation, followed by a debriefing session and lecture on the diagnosis, differential diagnosis, and management of inhalational airway injury secondary to a house fire. Debriefing methods may be left to the discretion of participants, but the authors have utilized advocacy-inquiry techniques. This scenario may also be run as an oral board case. Our residents are provided a survey at the completion of the debriefing session so they may rate different aspects of the simulation, as well as provide qualitative feedback on the scenario. The local institution's simulation center's electronic feedback form is based on the Center of Medical Simulation's Debriefing Assessment for Simulation in Healthcare (DASH) Student Version Short Form2 with the inclusion of required qualitative feedback if an element was scored less than a 6 or 7. Nine learners completed a feedback form. This session received all 6 & 7 scores (consistently effective/very good and extremely effective/outstanding, respectively) other than one isolated 5 score. This is a cost-effective method for reviewing inhalational airway injury diagnosis and management. The case may be modified for targeted audiences, expected resources, and learning objectives, such as removal of a bronchoscope availability in settings which are expected to be resource-limited. Some readers may choose to focus on other aspects of burn management instead of airway securement such as cyanide and/or carbon monoxide toxicity. We encourage readers to limit the number of learning objectives because airway algorithms and troubleshooting for this scenario was a rich, stand-alone debriefing. There was not enough time to review in detail all nuanced aspects of the burned patient, including: Lund-Browder versus rule of 9's, modified Brooke versus Parkland formulas, indications for and completion of escharotomies, and/or identification and treatment of cyanide and carbon monoxide toxicity.

Pre-Hospital and Post-Hospital Quality of Care in Traumatic Spinal Column and Cord Injuries in Iran.

A retrospective study. The quality of care (QoC) for spinal column/cord injury patients is a major health care concern. This study aimed to implement the QoC assessment tool (QoCAT) in the National Spinal Cord/Column Injury Registry of Iran (NSCIR-IR) to define the current state of pre- and post-hospital QoC of individuals with Traumatic Spinal Column and Spinal Cord Injuries (TSC/SCIs). The QoCAT, previously developed by our team to measure the QoC in patients with TSC/SCIs, was implemented in the NSCIR-IR. The pre-hospital QoC was evaluated through a retrospective analysis of NSCIR-IR registry data. Telephone interviews and follow-ups of patients with SCI evaluated the QoC in the post-hospital phase. In the pre-hospital phase, cervical collars and immobilization were implemented in 46.4% and 48.5% of the cases, respectively. Transport time from the scene to the hospital was documented as <1hour and <8hours in 33.4% and 93.9% of the patients, respectively. Post-hospital indicators in patients with SCI revealed a first-year mortality rate of 12.5% (20/160), a high incidence of secondary complications, reduced access to electrical wheelchairs (4.2%) and modified cars (7.7%), and low employment rate (21.4%). These findings revealed a significant delay in transport time to the first care facilities, low use of immobilization equipment indicating low pre-hospital QoC. Further, the high incidence of secondary complications, low employment rate, and low access to electrical wheelchairs and modified cars indicate lower post-hospital QoC in patients with SCI. These findings imply the need for further planning to improve the QoC for patients with TSC/SCIs.

Changing Epidemiology and Functional Outcomes of Inpatient Rehabilitation in Asian Traumatic Brain Injury Cases before and during the COVID-19 Pandemic: A Retrospective Cohort Study.

This study aimed to compare acute injury and rehabilitation characteristics for traumatic brain injury (TBI) inpatients during the pre and post COVID-19 pandemic periods. A retrospective study of TBI inpatients between 1 April 2018 and 31 December 2019 (pre COVID-19 period), and 1 July 2020 and 31 March 2022 (post COVID-19 period) was performed to compare demographics, premorbid comorbidity, TBI characteristics, rehabilitation complications, admission and discharge functional independence measure (FIM®), length of stay and discharge status. A total of 187 data sets were analyzed (82 pre COVID-19 and 105 post COVID-19). Post COVID-19 TBI inpatients were older by 11 years (pre COVID-19 mean 55 years vs. post COVID-19 mean 66 years, and p < 0.001), with 23% higher female inpatients (pre COVID-19 13.4% vs. post COVID-19 36.2%, and p < 0.001) and 25% higher presence of comorbidities (pre COVID-19 52.4% vs. post COVID-19 77.1%, and p < 0.001). In the post COVID-19 group, total discharge FIM (Td-FIM) was significantly lower by ~12 points (pre COVID-19 94.5 vs. post COVID-19 82, and p = 0.011), Td-FIM ≥ 91 was lower by ~18% (pre COVID-19 53.7% vs. post COVID-19 36.2%, and p = 0.017), and the need for caregivers increased by ~17% (pre COVID-19 68% vs. post COVID-19 85.4%, and p = 0.006) Conclusions: Our findings signal a demographic shift towards older, frailer TBI with lower functional independence levels post COVID-19.

Combined pelvic and acetabular injuries: clinical features and treatment strategies of a unique injury pattern

BackgroundTo explore the clinical characteristics of patients with unstable pelvic fractures combined with acetabular fractures and to discuss the treatment strategies for such patients to help guide treatment.MethodsWe retrospectively assessed 24 patients admitted to our hospital from June 2018 to June 2022 with unstable pelvic fractures combined with acetabular fractures, including 15 male patients and 9 female patients with a mean age of 44.8 years. According to the Tile pelvic fracture classification, 15 cases were type B, and 9 cases were type C. The acetabular fractures were classified using the Letournel–Judet classification. There were 8 transverse fractures, 4 transverse and posterior wall fractures, 3 anterior and posterior hemitransverse fractures, 6 both-column fractures, 2 T-shaped fractures and 1 anterior column fracture. We recorded the cause of the patient's injury and vital signs on admission and assessed the patient's treatment strategy and prognosis.ResultsAll patients completed the surgery successfully, and the follow-up ranged from 6 to 42 months, with a mean of 23 months. The healing time for pelvic fractures ranged from 11 to 21 weeks, with a mean of 14.8 weeks, and the postoperative displacement of the posterior pelvic ring ranged from 1.2 to 9.0 mm, with a mean of 3.5 mm. The final clinical outcome at follow-up was evaluated using the Majeed scale: excellent in 11 cases, good in 10 cases and fair in 3 cases; the excellent rate was 87.5%. The time to healing of the acetabular fracture ranged from 13 to 25 weeks, with a mean of 15.9 weeks, and the postoperative displacement of the acetabular fracture ranged from 0.6 to 5.2 mm, with a mean of 1.9 mm. Hip function was assessed at the final follow-up using a modified Merle D’ Aubigné and Postel scale: there were 9 excellent, 11 good and 4 acceptable scores; an excellent rate of 83.3% was achieved.ConclusionPatients with unstable pelvic fractures combined with acetabular fractures suffer severe trauma and complex mechanisms of injury. Treatment needs to be individualized, taking into account the patient's physiological status, fracture classification and degree of displacement.

Epidemiology and severity of traumatic dental injuries in permanent teeth: A 20-year retrospective study.

This study aimed to assess the traumatic dental injuries (TDIs) in permanent dentition among patients who attended at the outpatient clinic of a Brazilian dental school, during the last 20 years, and to investigate factors associated with the severity of these injuries. Clinical records of patients who attended a specialized center for dental trauma care in Brazil presenting at least one TDI in a permanent tooth, between the years 2000 and 2019, were reviewed. The data recorded were sex, age, affected arch, etiology, number, and type of the teeth affected, and classification and severity of the TDIs. The diagnosis and classification of the TDIs were based on the guidelines of the International Association of Dental Traumatology (IADT). The severity of each patient's injuries was defined as mild, moderate, or severe. Descriptive statistics, chi-square and multinomial regression analyses were used to evaluate the results. The significance level was set at 5%. A total of 837 clinical records were included, totaling 2357 teeth. Males were more prevalent than females. The patients' age ranged from 5 to 71 years. The most common traumas were avulsion (n=512) and uncomplicated enamel-dentin fracture (n=488). Univariate analyses showed that there was a statistically significant association between age group (p=0.004), etiology (p=0.000) and number of teeth affected (p=0.000) with severity of dental trauma. In conclusion, TDIs that occurred in Piracicaba and region are epidemiologically similar to those found worldwide, and that more severe injuries are related to age range, etiology and number of teeth affected.

Ten-Year Analysis of Complications Related to Simple Basilar Skull Fractures in Children Presenting to a Trauma Center.

Head trauma is a common presenting complaint among children requiring urgent medical attention, accounting for more than 600,000 emergency department (ED) visits annually, 4% to 30% of which identify skull fractures among the patient's injuries. Previous literature shows that children with basilar skull fractures (BSFs) are usually admitted for observation. We studied whether children with an isolated BSF have complications precluding them from safe discharge home from the ED. We performed a retrospective review of ED patients aged 0 to 18 years given a simple BSF diagnosis (defined by nondisplaced fracture, with normal neurologic examination, Glasgow Coma Score of 15, no intracranial hemorrhage, no pneumocephalus) during a 10-year period to identify complications associated with their injury. Complications were defined as death, vascular injury, delayed intracranial hemorrhage, sinus thrombosis, or meningitis. We also considered hospital length of stay (LOS) longer than 24 hours or any return visit within 3 weeks of the original injury. Of the 174 patients included in the analysis, there were no deaths, cases of meningitis, vascular injury, nor delayed bleeding events. Thirty (17.2%) patients required a hospital LOS longer than 24 hours and 9 (5.2%) returned to the hospital within 3 weeks of discharge. Of those with LOS longer than 24 hours, 22 (12.6%) patients needed subspecialty consultation or intravenous fluids, 3 (1.7%) had cerebrospinal fluid leak, and 2 (1.2%) had a concern for facial nerve abnormality. On the return visits, only 1 (0.6%) patient required readmission for intravenous fluids because of nausea and vomiting. Our findings suggest that patients with uncomplicated BSFs can be safely discharged from the ED if the patient has reliable follow-up, is tolerating oral fluids, has no evidence of cerebrospinal fluid leak, and has been evaluated by appropriate subspecialists before discharge.

748 Accidental Thermal Injury From Ignition of Home Oxygen: Is Burn Center Admission Advantageous?

Abstract Introduction Home oxygen therapy is available for the supportive treatment of patients with chronic lung disease. Nevertheless, complications associated with home oxygen use have been well described. The typical injury pattern associated with the accidental ignition of home oxygen does not mandate emergent intubation. However, due to the thermal component of the injury, patients are initially directed towards admission to burn units. The recent stress applied to the healthcare system by COVID-19 has highlighted the potential benefit of flexibility in the disposition of injured patients. In particular, we wanted to determine if there is a demonstrable benefit from admission to an American Burn Association (ABA) verified burn center for patients presenting with home oxygen ignition injuries. Methods After obtaining approval from our local Institutional Review Board, we conducted a retrospective review of our institution's ABA-verified burn center database from January 2016 through May 2022. Individual charts were inspected for discrete data points related to the general descriptor of the patient's injuries, comorbidities, and hospital course. Using independent samples t-tests, we compared patients admitted to the burn service with those primarily cared for by non-burn service teams. Results We identified 49 adult patients admitted with burn injuries associated with home oxygen use during the study period. These patients were divided into those intubated at or near the time of admission and those managed without intubation. Of the 29 patients intubated on admission, the burn service managed 19 of these patients, and non-burn services managed 10. There were no identified differences in the outcomes of ventilator days, days in the ICU, total length of stay, or mortality between the two groups. Similarly, we examined the 20 patients admitted without intubation. The burn service managed 7 of these patients, and non-burn services managed 13. Again, the two groups had no identified differences in the outcomes of days in the ICU, total length of stay, or mortality. Conclusions This single-center review revealed no difference in outcomes between patients cared for in an ABA-verified burn center versus non-burn services for home oxygen ignition injury. From a care perspective and resource utilization, the outcomes appear similar. Further, we note that patients required only brief periods of mechanical ventilation – supportive of the opportunity to avoid intubation in these patients. Prevention efforts, like those in the burn center, need to continue, and further studies must be done to confirm these preliminary findings. Applicability of Research to Practice These findings are supportive of potential opportunities to wisely use Burn Center capacity.

MACHINE LEARNING MODELS FOR PREDICTING ACUTE KIDNEY INJURY IN PATIENTS WITH SEPSIS-ASSOCIATED ACUTE RESPIRATORY DISTRESS SYNDROME.

Background: Acute kidney injury (AKI) is a prevalent and serious complication among patients with sepsis-associated acute respiratory distress syndrome (ARDS). Prompt and accurate prediction of AKI has an important role in timely intervention, ultimately improving the patients' survival rate. This study aimed to establish machine learning models to predict AKI via thorough analysis of data derived from electronic medical records. Method: The data of eligible patients were retrospectively collected from the Medical Information Mart for Intensive Care III database from 2001 to 2012. The primary outcome was the development of AKI within 48 hours after intensive care unit admission. Four different machine learning models were established based on logistic regression, support vector machine, random forest, and extreme gradient boosting (XGBoost). The performance of all predictive models was evaluated using the area under receiver operating characteristic curve, precision-recall curve, confusion matrix, and calibration plot. Moreover, the discrimination ability of the machine learning models was compared with that of the Sequential Organ Failure Assessment (SOFA) model. Results; Among 1,085 sepsis-associated ARDS patients included in this research, 375 patients (34.6%) developed AKI within 48 hours after intensive care unit admission. Twelve predictive variables were selected and further used to establish the machine learning models. The XGBoost model yielded the most accurate predictions with the highest area under receiver operating characteristic curve (0.86) and accuracy (0.81). In addition, a novel shiny application based on the XGBoost model was established to predict the probability of developing AKI among patients with sepsis-associated ARDS. Conclusions: Machine learning models could be used for predicting AKI in patients with sepsis-associated ARDS. Accordingly, a user-friendly shiny application based on the XGBoost model with reliable predictive performance was released online to predict the probability of developing AKI among patients with sepsis-associated ARDS.

Clinical characteristics of patients with snow sports trauma transported to a trauma care center: A retrospective observational study

BackgroundSnow sports are a popular recreational activity; however, the incidence of injury of snow sports can be high for skiers and snowboarders. Our hospital receives severe trauma cases from snow resorts and hospitals throughout the region. This study aimed to determine whether the risk of snow sports-related major trauma that requires emergency surgery under general anesthesia varies by the equipment and injury mechanism. MethodsThis retrospective cohort study included patients with snow sports trauma referred to Gifu University Hospital, Japan between November 2010 and March 2020. We analyzed the need for emergency operation under general anesthesia within 24 h using Fisher's exact test. We identified 106 patients: (1) 90 in the snowboarders’ group and 16 in the skiers’ group or (2) 46 in the fall after jumping group (jumping group), 27 in the collide with other people and obstacle group (collision group), and 33 in the fall during gliding group (gliding group). ResultsSnowboarders were nearly twice as likely as skiers to require emergency surgery under general anesthesia (44% vs. 25%; p = 0.236]. No significant associations were found between emergency surgery under general anesthesia and injury mechanism, but half of the patients in the jumping group required emergency surgery. ConclusionsSnowboard as equipment and falls after jumping as a mechanism of injury tended to be associated with emergency surgery under general anesthesia, with no significant differences. In order to provide adequate resources for snow sports trauma, the cause of the patient's injury is strongly related to the urgency of the condition, and transport to a trauma center should be actively considered. Further studies are warranted with respect to the effects of personal protective equipment and skill level.

Return to Play after Posterior Cruciate Ligament Injuries.

Posterior cruciate ligament injuries can be treated conservatively with a structured rehabilitation program or with surgical reconstruction. Treatment algorithms are based on a variety of factors including the patient's presentation, physical exam, and desired level of activity. The goal is to return the patient to their athletic pursuits with a stable and pain-free knee. Return to play and activities should be individualized based on the patient's injury and progression through rehabilitation. This article provides a review of the current treatments for posterior cruciate ligament injuries and the respective rehabilitation protocols, outcomes after each treatment option, and specific return to play criteria. Current research shows excellent outcomes and return to play with conservative treatment of isolated posterior cruciate ligament injuries. Return to play algorithms stress the importance of quadriceps strengthening throughout the recovery process and emphasize inclusion of plyometrics and sport-specific training. Rehabilitation plays a critical role in the outcome after posterior cruciate ligament injury and the ability to return to athletics. The primary focus of post-injury or post-operative rehabilitation is to restore function, as it relates to range of motion, strength, and proprioception, while mitigating swelling and pain. The patients' desired sport and level of play dictate return to play timelines. The literature supports the use of non-operative management of isolated PCL injuries in athletes and non-athletes with excellent functional and patient-reported outcomes.

Feasibility of SMS booster for alcohol reduction in injury patients in Tanzania.

Alcohol use is associated with 3 million annual deaths globally. Harmful alcohol use, which is associated with a high burden of disease in low- and middle-income countries (LMICs), often increases the probability of traumatic injury. Treatments for harmful alcohol use in LMICs, such as Tanzania, lack trained personnel and adequate infrastructure. The aim of this study was to assess the feasibility of using SMS boosters to augment a hospital based brief negotiational intervention (BNI) in this low resourced setting. We conducted a three stage, four arm feasibility trial of a culturally adapted BNI for injury patients with harmful and hazardous drinking admitted to Kilimanjaro Christian Medical Centre (KCMC) in Moshi, Tanzania. Post hospital discharge, two of the four arms included patients receiving either a standard or personalized short message service (SMS) booster to enhance and or perpetuate the effect of the in-hospital BNI. Text messages were sent weekly throughout a 3-month follow-up period. SMS feasibility was assessed according to the TIDier checklist evaluating what, when, how much, tailoring processes, modifications and how well (intervention fidelity). Data was collected with SMS logs and short answer surveys to participants. A total of 41 study participants were assigned to each receive 12 SMS over a three-month period; 38 received messages correctly, 3 did not receive intended messages, and 1 received a message who was not intended to. Of the 258 attempted texts, 73% were successfully sent through the messaging system. Of the messages that failed delivery, the majority were not able to be sent due to participants traveling out of cellular service range or turning off their phones. Participants interviewed in both booster arms reported that messages were appropriate, and that they would appreciate the continuation of such reminders. At 6-month follow-up, 100% (n = 11) of participants interviewed believed that the boosters had a positive impact on their behavior, with 90% reporting a large impact. This study demonstrated feasibility and acceptability of the integration of SMS mobile health technology to supplement this type of nurse-led BNI. SMS booster is a practical tool that can potentially prolong the impact of a brief hospital based intervention to enact behavioral change in injury patients with AUD.
