Purpose: Most blunt thoracic aortic injuries (BTAIs) may be treated using thoracic endovascular aortic repair (TEVAR), and most blunt abdominal traumas (BATs) are managed conservatively. We hypothesized that severe trauma that needs TEVAR may increase the risk of delayed intra-abdominal hemorrhage in patients with concomitant BTAI and BAT because of the potential hemorrhagic shock, disseminated intravascular coagulopathy, blood loss, consequent need for blood transfusion, and procedure-associated heparinization. Materials and Methods: From 2015 to 2019, blunt trauma patients with concomitant severe chest trauma and abdominal trauma who could be managed conservatively were studied. The probability of delayed intra-abdominal hemorrhage was compared between patients with concomitant BTAI who received or did not undergo TEVAR. Propensity score matching (PSM), inverse probability of treatment weighting (IPTW), and multivariate logistic regression (MLR) were used to eliminate discrepancies between these 2 groups. Results: Among the 341 studied patients, there were 26 patients with BTAI, and 19 of them underwent TEVAR. Delayed intra-abdominal hemorrhage was observed in 4 patients (21.1%, 4/19) who underwent TEVAR. Both PSM and IPTW showed that patients who underwent TEVAR for concomitant BTAI had a greater delayed need for blood transfusions and a larger proportion of delayed intra-abdominal hemorrhage than patients who did not undergo the procedure. The MLR analysis showed that TEVAR for BTAI was an independent risk factor for delayed intra-abdominal hemorrhage (odds ratio: 10.534, 95%, p<0.001). Conclusion: An increased probability of delayed intra-abdominal hemorrhage in patients with BAT (who could be managed conservatively) was observed in patients who underwent TEVAR for concomitant BTAI. Clinical Impact: More attention should be give in patients with high grade aortic injuries and concomitant abdominal trauma. [ABSTRACT FROM AUTHOR]

Purpose: Adequate resuscitation and definitive hemostasis are both important in the management of hemorrhage related to pelvic fracture. The goal of this study was to analyze the relationship between the amount of blood transfused before transcatheter arterial embolization (TAE) and the clinical outcome later in the disease course. Methods: Patients with pelvic fractures who underwent TAE for hemostasis from January 2018 to December 2019 were studied. The characteristics of patients who received blood transfusions of >2 U (1000 mL) and ≤2 U before TAE were compared. The mortality rate, blood transfusion-related complications, and length of stay were compared between these two groups. Results: Among the 75 studied patients, 39 (52.0%) received blood transfusions of ≤2 U before TAE, and the other 36 (48.0%) patients received blood transfusions of >2 U before TAE. The incidence rates of systemic inflammatory response syndrome, sepsis, and coagulopathy were significantly higher in the >2 U group (97.2% vs 81.1%, P =.027; 50.0% vs 27.0%, P =.045; and 44.4% vs 5.4%, P <.01, respectively). After nonsurvivors were excluded, the >2 U group had a significantly higher proportion (43.8% vs 14.7%, P <.001) of prolonged intensive care unit (ICU) length of stay (7 days or more) and a longer hospital length of stay (33.8 ± 15.1 vs 21.9 ± 94.0, P <.01) than the ≤2 U group. Pre-TAE blood transfusion >2 U serves as an independent risk factor for prolonged ICU length of stay and increased hospital length of stay. Conclusion: Early hemostasis for pelvic fracture-related hemorrhage is suggested to prevent pre-TAE blood transfusion-associated adverse effects of blood transfusion. [ABSTRACT FROM AUTHOR]

Purpose: Whole-body computed tomography (WBCT) scans are frequently used for trauma patients, and sometimes, nontraumatic findings are observed. We aimed to investigate the characteristics of patients with nontraumatic findings on WBCT.Methods: From 2013 to 2016, adult trauma patients who underwent WBCT were enrolled. The proportions of nontraumatic findings in different anatomical regions were studied. Nontraumatic findings were classified and evaluated as clinically important findings and findings that needed no further follow-up or treatment. The characteristics of the patients with nontraumatic findings were analyzed and compared with those of patients without nontraumatic findings.Results: Two hundred seventeen patients were enrolled in this study during the 3-year study period, and 89 (41.0%) patients had nontraumatic findings. Nontraumatic findings were found more frequently in the abdomen (69.2%) than in the head/neck (17.3%) and chest regions (13.5%). In total, 31.3% of the findings needed further follow-up or treatment. Patients with nontraumatic findings that needed further management were significantly older than those without nontraumatic findings (57.3 vs. 38.9; P < .001), particularly those with abdominal nontraumatic findings (57.9 vs. 41.3; P < .001). A significantly higher proportion of women were observed in the group with head/neck nontraumatic findings that needed further management than in the group without nontraumatic findings (56.3% vs 24.9%; P = .015).Conclusions: Whole-body computed tomography could provide alternative benefits for nontraumatic findings. Whole-body computed tomography images should be read carefully for nontraumatic findings, particularly for elderly patients or the head/neck region of female patients. A comprehensive program for the follow-up of nontraumatic findings is needed. [ABSTRACT FROM AUTHOR]

Introduction: In the evaluation of haemorrhage in trauma patients with pelvic fractures, contrast extravasation (CE) on computed tomography (CT) scan often implies active arterial bleeding. However, the absence of CE on CT scan does not always exclude the need for transcatheter arterial embolisation (TAE) to achieve haemostasis. In the current study, we evaluated the factors associated with the need for TAE in patients without CE on CT scan. These factors may be evaluated as adjuncts to CT scanning in the management of patients with pelvic fractures. Methods: We retrospectively reviewed our trauma registry and medical records of patients with pelvic fractures. When CE was observed, indicating active haemorrhage, the patients underwent TAE to achieve haemostasis. In contrast, patients without CE were held for observation and treatment of their injuries, and if their condition deteriorated after a delayed interval, they were then also referred for TAE if no other focus of haemorrhage was found. Patients without CE on CT scan but with retroperitoneal haemorrhage requiring TAE were investigated. Their demographic characteristics, associated injuries, fracture patterns, and changes in systolic blood pressure were described and analysed. Results: In total, 201 patients with pelvic fracture underwent CT scan examination; 47 (23.4%) had CE by CT scan, whereas the other 154 (76.6%) did not. Of the 154 patients who did not show CE by CT scan, 124 (80.5%) patients never underwent TAE; however, 30 (19.5%) of these patients did eventually undergo TAE. In comparing the patients who underwent TAE to those who did not undergo TAE among patients without CE on CT scan, the systolic blood pressure (SBP) on arrival (median: 100.0 mmHg vs 136.0 mmHg, p<0.01) and the lowest SBP recorded in the ED (median: 68.0 mmHg vs 129.0 mmHg, p<0.01) were significantly lower in the patients who underwent TAE. The ROC curve analysis revealed that the most appropriate cutoff value of decrement of SBP (SBP on arrival minus the lowest SBP in the ED) was 30 mmHg (AUC=0.89). Conclusion: In the management of pelvic fracture patients, greater attention should be directed toward patients with relative hypotension. The higher likelihood of haemodynamic deterioration and the need for TAE for haemorrhage control should remain under consideration in such cases, despite the absence of CE by CT scan.

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been an established life-saving procedure for adult trauma patients, but the evidence for its use in pediatric patients is still under question. The purpose of this study was to examine the outcome of REBOA in pediatric patients., Methods: We retrospectively analyzed observational cohort data from the American College of Surgeons-Trauma Quality Improvement Program from 2017 to 2019. We analyzed 183 506 trauma patients aged 7-18, and 111 patients were matched by propensity score analysis. Basic demographics, injury severity, trauma type, and clinical outcomes of the patients receiving REBOA and those not receiving REBOA were compared. In the REBOA patients, a subgroup analysis was performed to evaluate the potential influence of age and body weight on the outcomes of REBOA., Results: After the pretreatment factors were balanced for the REBOA and no-REBOA groups, the patients in the REBOA group had more transfused packed red blood cells within the first 4 hours (3250 mL vs. 600 mL, p<0.001), and the mortality rate was higher in the REBOA group, but it did not reach statistical significance (56.8% vs. 36.5%, p=0.067). No significant difference was detected regarding in-hospital complications. In the subgroup analysis of the patients who received REBOA, we discovered no significant difference in mortality and complications between the subgroups when compared by age (>15 years old/≤15 years old) or weight (>58 kg or ≤58 kg)., Conclusions: Pediatric trauma patients who received REBOA were not significantly associated with an increased risk of mortality when compared with no-REBOA patients with matched basic demographics and pretreatment factors. Younger age and lighter body weight did not seem to influence the outcomes of REBOA regarding survival and complications., Level of Evidence: Level III., Competing Interests: None declared., (Copyright © Author(s) (or their employer(s)) 2024.

Background: The impact of resuscitative endovascular balloon occlusion of the aorta (REBOA) on traumatic brain injuries remains uncertain, with potential outcomes ranging from neuroprotection to exacerbation of the injury. The study aimed to evaluate consciousness recovery in patients with blunt trauma with shock and traumatic brain injuries., Material and Methods: Data were obtained from the American College of Surgeons Trauma Quality Improvement Program from 2017-2019. During the study period, 3,138,896 trauma registries were examined, and 16,016 adult patients with blunt trauma, shock, and traumatic brain injuries were included. Among these, 172 (1.1%) underwent REBOA. Comparisons were conducted between patients with and without REBOA after implementing 1:3 propensity score matching to mitigate disparities. The primary outcome was the highest Glasgow Coma Scale score during admission. The secondary outcomes encompassed the volume of blood transfusion, the necessity for hemostatic interventions and therapeutic neurosurgery, and mortality rate., Results: Through well-balanced propensity score matching, a notable difference in mortality rate was observed, with 59.7% in the REBOA group and 48.7% in the non-REBOA group (P=0.015). In the REBOA group, the median 4-hour red blood cell transfusion was significantly higher (2800 mL [1500, 4908] vs. 1300 mL [600, 2500], P<0.001). The REBOA group required lesser hemorrhagic control surgeries (31.8% vs. 47.7%, P<0.001) but needed more transarterial embolization interventions (22.2% vs 15.9%, P=0.076). The incidence of therapeutic neurosurgery was 5.1% in the REBOA group and 8.7% in the non-REBOA group (P=0.168). Among survivors in the REBOA group, the median highest Glasgow Coma Scale score during admission was significantly greater for both total (11 [8, 14] vs. 9 [6, 12], P=0.036) and motor components (6 [4, 6] vs. 5 [3, 6], P=0.037). The highest GCS score among the survivors with predominant pelvic injuries was not different between the two groups (11 [8, 13] vs. 11 [7, 14], P=0.750)., Conclusions: Patients experiencing shock and traumatic brain injury have high mortality rates, necessitating swift resuscitation and prompt hemorrhagic control. The use of REBOA as an adjunct for bridging definitive hemorrhagic control may correlate with enhanced consciousness recovery., (Copyright © 2024 The Author(s).

Background: The influence of COVID-19 infection on elite athletes remains largely unknown, especially on baseball players. The goal of this study is to examine the actual performance of infected elite baseball players from the Chinese Professional Baseball League (CPBL) from a sabermetric point of view., Methods: This was a retrospective observational cohort study. CPBL players who were infected with COVID-19 from April 27 th to May 31 st , 2022, were eligible for this study. The performance of study participants before and after COVID-19 infection was compared, and statistics from the batters and pitchers were analyzed separately., Results: During the study interval, 56 players were infected with COVID-19, including 35 batters and 21 pitchers. After excluding injured players and players with inadequate playing opportunities, 23 batters and 12 pitchers were enrolled. For batters, there were no significant differences before and after COVID-19 infection. However, batters older than 28 years of age showed a decline in slugging percentage (0.372 vs. 0.292, P=0.049). Analysis of pitchers revealed significantly boosted fastball velocity after COVID-19 infection (142.10 km/h vs. 142.82 km/h, P=0.028) and improved strikeouts per nine innings (6.89 vs. 8.56, P=0.021)., Conclusions: COVID-19 might have a potential influence on professional baseball players. For batters, veteran players more than 28 years of age were more likely to be negatively affected by COVID-19, whereas the effect of COVID-19 on pitchers was generally positive, with significantly improved fastball velocity and K/9 numbers.

Background: Most trauma-related studies are focused on short-term survival and complications within the index admission, and the long-term outcomes beyond discharge are mainly unknown. The purpose of this study was to analyze the data from the National Health Insurance Research Database (NHIRD) and to assess the long-term survival of major trauma patients after being discharged from the index admission., Material and Methods: This retrospective, observational study included all patients with major trauma (injury severity score ≥16) in Taiwan from 2003 to 2007, and a 10-year follow-up was conducted on this cohort. Patients aged 18-70 who survived the index admission were enrolled. Patients who survived less than one year after discharge (short survival, SS) and those who survived for more than one year (long survival, LS) were compared. Variables, including preexisting factors, injury types, and short-term outcomes and complications, were analyzed, and the 10-year Kaplan-Meier survival analysis was conducted., Results: In our study, 9896 patients were included, with 2736 in the SS group and 7160 in the LS group. Age, sex, comorbidities, low income, cardiopulmonary resuscitation event, prolonged mechanical ventilation, prolonged ICU length of stay (LOS), and prolonged hospital LOS were identified as the independent risk factors of SS. The 10-year cumulative survival for major trauma patients was 63.71%, and the most mortality (27.64%) occurred within the first year after discharge., Conclusion: 27.64% of patients would die one year after being discharged from major trauma. Major trauma patients who survived the index admission still had significantly worse long-term survival than the general population, but the curve flattened and resembled the general population after one year., (Copyright © 2023 The Author(s).
