ABSTRACT
PURPOSE: To evaluate the diagnostic performance of lung ultrasound (LUS) in screening for SARS-CoV-2 infection in patients requiring surgery. METHODS: Patients underwent a LUS protocol that included a scoring system for screening COVID-19 pneumonia as well as RT-PCR test for SARS-CoV-2. The receiver operator characteristic (ROC) curve was determined for the relationship between LUS score and PCR test results for COVID-19. The optimal threshold for the best discrimination between non-COVID-19 patients and COVID-19 patients was calculated. RESULTS: Among 203 patients enrolled (mean age 48 years; 82 males), 8.3% were COVID-19-positive; 4.9% were diagnosed via the initial RT-PCR test. Of the patients diagnosed with SARS-CoV-2, 64.7% required in-hospital management and 17.6% died. The most common ultrasound findings were B lines (19.7%) and a thickened pleura (19.2%). The AUC of the ROC curve of the relationship of LUS score with a cutoff value >8 versus RT-PCR test for the assessment of SARS-CoV-2 pneumonia was 0.75 (95% CI 0.61-0.89; sensitivity 52.9%; specificity 91%; LR (+) 6.15, LR (-) 0.51). CONCLUSION: The LUS score in surgical patients is not a useful tool for screening patients with potential COVID-19 infection. LUS score shows a high specificity with a cut-off value of 8.

IMPORTANCE: The effect of high-flow oxygen therapy vs conventional oxygen therapy has not been established in the setting of severe COVID-19. OBJECTIVE: To determine the effect of high-flow oxygen therapy through a nasal cannula compared with conventional oxygen therapy on need for endotracheal intubation and clinical recovery in severe COVID-19. DESIGN, SETTING, AND PARTICIPANTS: Randomized, open-label clinical trial conducted in emergency and intensive care units in 3 hospitals in Colombia. A total of 220 adults with respiratory distress and a ratio of partial pressure of arterial oxygen to fraction of inspired oxygen of less than 200 due to COVID-19 were randomized from August 2020 to January 2021, with last follow-up on February 10, 2021. INTERVENTIONS: Patients were randomly assigned to receive high-flow oxygen through a nasal cannula (n = 109) or conventional oxygen therapy (n = 111). MAIN OUTCOMES AND MEASURES: The co-primary outcomes were need for intubation and time to clinical recovery until day 28 as assessed by a 7-category ordinal scale (range, 1-7, with higher scores indicating a worse condition). Effects of treatments were calculated with a Cox proportional hazards model adjusted for hypoxemia severity, age, and comorbidities. RESULTS: Among 220 randomized patients, 199 were included in the analysis (median age, 60 years; n = 65 women [32.7%]). Intubation occurred in 34 (34.3%) randomized to high-flow oxygen therapy and in 51 (51.0%) randomized to conventional oxygen therapy (hazard ratio, 0.62; 95% CI, 0.39-0.96; P = .03). The median time to clinical recovery within 28 days was 11 (IQR, 9-14) days in patients randomized to high-flow oxygen therapy vs 14 (IQR, 11-19) days in those randomized to conventional oxygen therapy (hazard ratio, 1.39; 95% CI, 1.00-1.92; P = .047). Suspected bacterial pneumonia occurred in 13 patients (13.1%) randomized to high-flow oxygen and in 17 (17.0%) of those randomized to conventional oxygen therapy, while bacteremia was detected in 7 (7.1%) vs 11 (11.0%), respectively. CONCLUSIONS AND RELEVANCE: Among patients with severe COVID-19, use of high-flow oxygen through a nasal cannula significantly decreased need for mechanical ventilation support and time to clinical recovery compared with conventional low-flow oxygen therapy.

BACKGROUND: There is evidence in favor of using the ultrasound as the primary screening tool in looking for an occult cardiac injury. We report on a prospective single-center study to determine the diagnostic accuracy of chest ultrasound for the diagnosis of occult penetrating cardiac wounds in a low-resource hospital from a middle-income country. METHODS: Data were collected prospectively. We included all consecutive patients 14 years and older who presented to the Emergency Trauma Unit with (1) penetrating injuries to the precordial area and (2) a systolic blood pressure ≥ 90 mmHg (hemodynamically stable). The main outcome measures were sensitivity, specificity, and positive and negative predictive values of ultrasound compared with those of the pericardial window, which was the standard test. RESULTS: A total of 141 patients met the inclusion criteria. Our results showed that for diagnosing an occult cardiac injury, the sensitivity of the chest ultrasonography was 79.31%, and the specificity was 92.86%. Of the 110 patients with a normal or negative ultrasound, six had a positive pericardial window. All of these patients had left hemothoraces. None of them required further cardiac surgical interventions. CONCLUSION: We found that ultrasound was 79% sensitive and 92% specific for the diagnosis of occult penetrating cardiac wounds. However, it should be used with caution in patients with injuries to the cardiac zone and simultaneous left hemothorax.

BACKGROUND: The goal of our study was to evaluate the differences in care and clinical outcomes of patients with chest trauma between two hospitals, including one public trauma center (Pu-TC) and one private trauma center (Pri-TC). METHODS: Patients with thoracic trauma admitted from January 2012 to December 2018 at two level I trauma centers (Pu-TC: Hospital Universitario del Valle, Pri-TC: Fundación Valle del Lili) in Cali, Colombia, were included. Multivariable logistic regression was used to assess for differences in in-hospital mortality, adjusting for relevant demographic and clinical characteristics. RESULTS: A total of 482 patients were identified; 300 (62.2%) at the Pri-TC and 182 (37.8%) at the Pu-TC. Median age was 27 years (IQR 21-36) and median Injury Severity Score was 25 (IQR 16-26). 456 patients (94.6%) were male, and the majority had penetrating trauma [total 465 (96.5%); Pri-TC 287 (95.7%), Pu-TC 179 (98.4%), p 0.08]. All patients arrived at the emergency room with unstable hemodynamics. There were no statistically significant differences in post-operative complications, including retained hemothorax [Pri-TC 19 vs. Pu-TC 18], pneumonia [Pri-TC 14 vs. Pu-TC 14], empyema [Pri-TC 13 vs. Pu-TC 13] and mediastinitis [Pri-TC 6 vs. Pu-TC 2]. Logistic regression did, however, show a higher odds of mortality when patients were treated at the Pu-TC [OR 2.27 (95% CI 1.34-3.87, p < 0.001]. CONCLUSIONS: Our study found significant statistical differences in clinical outcomes between patients treated at a Pu-TC and Pri-TC. The results are intended to stimulate discussions to better understand reasons for outcome variability and ways to reduce it.

The shock index (SI) has been associated with predicting transfusion needs in trauma patients. However, its utility in penetrating thoracic trauma (PTTrauma) for predicting the Critical Administration Threshold (CAT) has not been well-studied. This study aimed to evaluate the prognostic value of SI in predicting CAT in PTTrauma patients and compare its performance with the Assessment of Blood Consumption (ABC) and Revised Assessment of Bleeding and Transfusion (RABT) scores. We conducted a prognostic type 2, single-center retrospective observational cohort study on patients with PTTrauma and an Injury Severity Score (ISS) > 9. The primary exposure was SI at admission, and the primary outcome was CAT. Logistic regression and decision curve analysis were used to assess the predictive performance of SI and the PTTrauma score, a novel model incorporating clinical variables. Of the 620 participants, 53 (8.5%) had more than one CAT. An SI > 0.9 was associated with CAT (adjusted OR 4.89, 95% CI 1.64-14.60). The PTTrauma score outperformed SI, ABC, and RABT scores in predicting CAT (AUC 0.867, 95% CI 0.826-0.908). SI is a valuable predictor of CAT in PTTrauma patients. The novel PTTrauma score demonstrates superior performance compared to existing scores, highlighting the importance of developing targeted predictive models for specific injury patterns. These findings can guide clinical decision-making and resource allocation in the management of PTTrauma.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is gaining popularity worldwide for managing hypotensive trauma patients. Vascular access complications related to REBOA placement have been reported, with some cases resulting in permanent morbidity. We aim to capitalize on the increase in literature to further describe and estimate the incidence of REBOA-associated vascular access complications in adult trauma patients. METHODS: We searched Medline, EMBASE, Scopus, and CINAHL for studies reporting vascular access complications of REBOA in adult trauma patients from inception to October 14, 2021. Studies reporting data from adult trauma patients who underwent REBOA insertion were eligible. Exclusion criteria included patients 15 years and younger, nontrauma patients, non-REBOA use, non-vascular access complications and patient duplication. Study data was abstracted using the PRISMA checklist and verified independently by three reviewers. Meta-analysis of proportions was performed using a random effects model with Freeman-Turkey double-arcsine transformation. Post hoc meta-regression by year of publication, sheath-size, and geographic region was also performed. The incidence of vascular access complications from REBOA insertion was the primary outcome of interest. Subgroup analysis was performed by degree of bias, sheath size, technique of vascular access, provider specialty, geographical region, and publication year. RESULTS: Twenty-four articles were included in the systematic review and the meta-analysis, for a total of 675 trauma patients who underwent REBOA insertion. The incidence of vascular access complications was 8% (95% confidence interval, 5%-13%). In post hoc meta-regression adjusting for year of publication and geographic region, the use of a smaller (7-Fr) sheath was associated with a decreased incidence of vascular access complications (odds ratio, 0.87; 95% confidence interval, 0.75-0.99; p = 0.046; R 2 = 35%; I 2 = 48%). CONCLUSION: This study provides a benchmark for quality of care in terms of vascular access complications related to REBOA insertion in adult trauma patients. Smaller sheath size may be associated with a decrease in vascular access complications. LEVEL OF EVIDENCE: Systematic Review and Meta-Analysis; Level III.

BACKGROUND: Penetrating thoracic injuries have a significant risk of morbi-mortality. Despite the advancements in damage control methods, a subset of patients with severe pulmonary vascular lesions and bronchial injuries persists. In some of these cases, post-traumatic pneumonectomy is required, and perioperative extracorporeal membrane oxygenation (ECMO) support may be required due to right ventricular failure and respiratory failure. CASE DESCRIPTION: A male was brought to the emergency department (ED) with a penetrating thoracic injury, presenting with massive right hemothorax and active bleeding that required ligation of the right pulmonary hilum to control the bleeding. Subsequently, he developed right ventricular dysfunction and ARDS, necessitating a dynamic hybrid ECMO configuration to support his condition and facilitate recovery. CONCLUSIONS: Penetrating thoracic injuries with severe pulmonary vascular lesions may need pneumonectomy to control bleeding. ECMO support reduces the associated mortality by decreasing the complications rate. A multidisciplinary team is essential to achieve good outcomes in severe compromised patients.

BACKGROUND: Systolic blood pressure (SBP) is a potential indicator that could guide when to use a resuscitative endovascular balloon occlusion of the aorta (REBOA) in trauma patients with life-threatening injuries. This study aims to determine the optimal SBP threshold for REBOA placement by analyzing the association between SBP pre-REBOA and 24-hour mortality in severely injured hemodynamically unstable trauma patients. METHODS: We performed a pooled analysis of the aortic balloon occlusion (ABO) trauma and AORTA registries. These databases record the details related to the use of REBOA and include data from 14 countries worldwide. We included patients who had suffered penetrating and/or blunt trauma. Patients who arrived at the hospital with a SBP pre-REBOA of 0 mm Hg and remained at 0 mm Hg after balloon inflation were excluded. We evaluated the impact that SBP pre-REBOA had on the probability of death in the first 24 hours. RESULTS: A total of 1,107 patients underwent endovascular aortic occlusion, of these, 848 met inclusion criteria. The median age was 44 years (interquartile range [IQR], 27-59 years) and 643 (76%) were male. The median injury severity score was 34 (IQR, 25-45). The median SBP pre-REBOA was 65 mm Hg (IQR, 49-88 mm Hg). Mortality at 24 hours was reported in 279 (32%) patients. Math modeling shows that predicted probabilities of the primary outcome increased steadily in SBP pre-REBOA below 100 mm Hg. Multivariable mixed-effects analysis shows that when SBP pre-REBOA was lower than 60 mm Hg, the risk of death was more than 50% (relative risk, 1.5; 95% confidence interval, 1.17-1.92; p = 0.001). DISCUSSION: In patients who do not respond to initial resuscitation, the use of REBOA in SBPs between 60 mm Hg and 80 mm Hg may be a useful tool in resuscitation efforts before further decompensation or complete cardiovascular collapse. The findings from our study are clinically important as a first step in identifying candidates for REBOA. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

INTRODUCTION: Venous-to-arterial carbon dioxide difference (Pv-aCO2) may reflect the adequacy of blood flow during shock states. We sought to test whether the development of Pv-aCO2 during the very early phases of resuscitation is related to multi-organ dysfunction and outcomes in a population of septic shock patients resuscitated targeting the usual oxygen-derived and hemodynamic parameters. METHODS: We conducted a prospective observational study in a 60-bed mixed ICU in a University affiliated Hospital. 85 patients with a new septic shock episode were included. A Pv-aCO2 value ≥ 6 mmHg was considered to be high. Patients were classified in four predefined groups according to the Pv-aCO2 evolution during the first 6 hours of resuscitation: (1) persistently high Pv-aCO2 (high at T0 and T6); (2) increasing Pv-aCO2 (normal at T0, high at T6); (3) decreasing Pv-aCO2 (high at T0, normal at T6); and (4) persistently normal Pv-aCO2 (normal at T0 and T6). Multiorgan dysfunction at day-3 was compared for predefined groups and a Kaplan Meier curve was constructed to show the survival probabilities at day-28 using a log-rank test to evaluate differences between groups. A Spearman-Rho was used to test the agreement between cardiac output and Pv-aCO2. Finally, we calculated the mortality risk ratios at day-28 among patients attaining normal oxygen parameters but with a concomitantly increased Pv-aCO2. RESULTS: Patients with persistently high and increasing Pv-aCO2 at T6 had significant higher SOFA scores at day-3 (p < 0.001) and higher mortality rates at day-28 (log rank test: 19.21, p < 0.001) compared with patients who evolved with normal Pv-aCO2 at T6. Interestingly, a poor agreement between cardiac output and Pv-aCO2 was observed (r2 = 0.025, p < 0.01) at different points of resuscitation. Patients who reached a central venous saturation (ScvO)2 ≥ 70% or mixed venous oxygen saturation (SvO2) ≥ 65% but with concomitantly high Pv-aCO2 at different developmental points (i.e., T0, T6 and T12) had a significant mortality risk ratio at day-28. CONCLUSION: The persistence of high Pv-aCO2 during the early resuscitation of septic shock was associated with more severe multi-organ dysfunction and worse outcomes at day-28. Although mechanisms conducting to increase Pv-aCO2 during septic shock are insufficiently understood, Pv-aCO2 could identify a high risk of death in apparently resuscitated patients.

Background and Aims: Multiple organ dysfunction (MOD) is a potentially reversible physiological disorder that involves two or more systems. Modified NEOMOD (Neonatal Multiple Organ Dysfunction score) scale could be a useful instrument to measure MOD and predict mortality. Our aim was to validate modified NEOMOD in patients from a neonatal intensive care unit (NICU) of a middle-income country. Methods: Diagnostic test study. Preterm newborns admitted NICU were included. Daily values were collected from birthday to Day 14. MOD was defined as at least one point in two or more systems. The lowest score is 0 and the maximum is 16. The outcome variable was mortality. Secondary outcomes were bronchopulmonary dysplasia, retinopathy of prematurity (ROP), late-onset neonatal sepsis (LONS), intraventricular hemorrhage (IVH) and length of hospital stay. Area under the curve (AUC) and Hosmer-Lemeshow test were calculated to evaluate scale discrimination and calibration. Logistic regression was used to estimate the association between daily modified NEOMOD score and death. Results: We included 273 patients who met the inclusion criteria. MOD incidence was 74.4%. The median gestational age in patients with MOD was 30 (interquartile range [IQR]: 27-33) and in patients without MOD it was 32 (IQR: 31-33) (p < 0.001). There were 40 deaths (14.6%), 38 (18.7%) from the MOD group and 2 (2.9%) from non-MOD group. On accumulated Day 7, AUC was 0.89 (95% confidence interval [CI]: 0.83-0.95). Modified NEOMOD had good calibration (X 2 = 2.94, p = 0.982). DBP (12.8% vs. 2.9%, p = 0.001), ROP (3.9% vs. 0%, p = 0.090), IVH (33% vs. 12.9%, p < 0.001), and LONS (36.5% vs. 8.6%, p < 0.001) frequency was higher in the MOD group than non-MOD group. Length of hospital stay also was higher in MOD group (median 21 days [IQR 7-44] vs. median 5 days [IQR 4-9], p = 0.004). Conclusion: Modified NEOMOD scale presents good discrimination and calibration for death in preterm children. This scale could help in clinical decision-making in real-time.
ABSTRACT
BACKGROUND: In this systematic review and meta-analysis, we examined the evidence on transjugular intrahepatic portosystemic shunt (TIPS) as a bridge to elective and emergency surgery in cirrhotic patients. We aimed to assess the perioperative characteristics, management approaches, and outcomes of this intervention, which is used to achieve portal decompression and enable the safe performance of elective and emergent surgery. METHODS: MEDLINE and Scopus were searched for studies reporting the outcomes of cirrhotic patients undergoing elective and emergency surgery with preoperative TIPS. The risk of bias was evaluated using the methodological index for non-randomized studies of interventions, and the JBI critical appraisal tool for case reports. The outcomes of interest were: 1. Surgery after TIPS; 2. Mortality; 3. Perioperative transfusions; and 4. Postoperative liver-related events. A DerSimonian and Laird (random-effects) model was used to perform the meta-analyses in which the overall (combined) effect estimate was presented in the form of an odds ratio (summary statistic). RESULTS: Of 426 patients (from 27 articles), 256 (60.1%) underwent preoperative TIPS. Random effects MA showed significantly lower odds of postoperative ascites with preoperative TIPS (OR = 0.40, 95% CI 0.22-0.72; I2 = 0%). There were no significant differences in 90-day mortality (3 studies: OR = 0.76, 95% CI 0.33-1.77; I2 = 18.2%), perioperative transfusion requirement (3 studies: OR = 0.89, 95% CI 0.28-2,84; I2 = 70.1%), postoperative hepatic encephalopathy (2 studies: OR = 0.97, 95% CI 0.35-2.69; I2 = 0%), and postoperative ACLF (3 studies: OR = 1.02, 95% CI 0.15-6.8, I2 = 78.9%). CONCLUSIONS: Preoperative TIPS appears safe in cirrhotic patients who undergo elective and emergency surgery and may have a potential role in postoperative ascites control. Future randomized clinical trials should test these preliminary results.

BACKGROUND: Previous observational studies showed higher rates of abdominal wall closure with the use of hypertonic saline in trauma patients with abdominal injuries. However, no randomized controlled trials have been performed on this matter. This double-blind randomized clinical trial assessed the effect of 3% hypertonic saline (HS) solution on primary fascial closure and the timing of abdominal wall closure among patients who underwent damage control laparotomy for bleeding control. METHODS: Double-blind randomized clinical trial. Patients with abdominal injuries requiring damage control laparotomy (DCL) were randomly allocated to receive a 72-h infusion (rate: 50 mL/h) of 3% HS or 0.9 N isotonic saline (NS) after the index DCL. The primary endpoint was the proportion of patients with abdominal wall closure in the first seven days after the index DCL. RESULTS: The study was suspended in the first interim analysis because of futility. A total of 52 patients were included. Of these, 27 and 25 were randomly allocated to NS and HS, respectively. There were no significant differences in the rates of abdominal wall closure between groups (HS: 19 [79.2%] vs. NS: 17 [70.8%]; p = 0.71). In contrast, significantly higher hypernatremia rates were observed in the HS group (HS: 11 [44%] vs. NS: 1 [3.7%]; p < 0.001). CONCLUSION: This double-blind randomized clinical trial showed no benefit of HS solution in primary fascial closure rates. Patients randomized to HS had higher sodium concentrations after the first day and were more likely to present hypernatremia. We do not recommend using HS in patients undergoing damage control laparotomy. Trial registration The trial protocol was registered in clinicaltrials.gov (identifier: NCT02542241).

BACKGROUND: The use of resuscitative endovascular balloon of the aorta (REBOA) is a useful strategy for bleeding control in placenta accreta spectrum (PAS) management. The incidence of complications associated with this procedure is variable. We report three cases of arterial thrombosis associated with REBOA, and we also analyze the factors that facilitated its occurrence. CASE REPORT: Three women with PAS, presented common femoral and external iliac arterial thrombosis after REBOA use. Among the contributing factors probably associated with thrombosis, we identified the absence of ultrasound guidance for vascular access and the not using of heparin during aortic occlusion. CONCLUSIONS: REBOA use is not exempt from complications and must be performed by experienced groups applying strategies to reduce the risks of complications.

PURPOSE: General surgeons, anesthesiologists, obstetricians and gynecologists (ob-gyns), and orthopedic surgeons are the vital disciplines to provide emergency surgery within a healthcare system. This paper aims to examine the relationship (if any) between multidimensional poverty (MDP) and GDP per-capita with the emergency surgery workforce density in Colombia. METHODS: We performed an ecological study, where the observation units were the 32 Colombian departments. The total numbers of general surgeons, anesthesiologists, ob-gyns, and orthopedic surgeons were obtained from the "Registro Unico Nacional de Talento Humano en Salud" (ReTHUS) registry. The 2020 population projections, the incidence of MDP and the GDP per capita were obtained from the Colombian National Administrative Department of Statistics. A spearman's correlation coefficient was calculated to measure the strength of the correlations between the surgical workforce density with MDP and GDP per-capita. RESULTS: There were significant moderate inverse linear correlations between the incidence of multidimensional poverty and workforce density. The correlation coefficients for the incidence of multidimensional poverty and the workforce density were - 0.5273, - 0.5620, - 0.4704, and - 0.4612 for surgeons, anesthesiologists, ob-gyns, and orthopedic surgeons, respectively. Conversely, the correlation coefficients for the GDP per-capita and the workforce density were 0.4045, 0.3822, 0.4404, and 0.3742 for surgeons, anesthesiologists, ob-gyns, and orthopedic surgeons, respectively. CONCLUSION: This study found that Colombian trauma and emergency surgery workforce density was inversely and directly correlated with multidimensional poverty and GDP per-capita levels, respectively. The relationship of these economic indicators with the surgical capacity deserves further investigation.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a damage control tool with a potential role in the hemodynamic resuscitation of severely ill patients in the civilian pre-hospital setting. REBOA ensures blood flow to vital organs by early proximal control of the source of bleeding. However, there is no consensus on the use of REBOA in the pre-hospital setting. This article aims to perform a systematic review of the literature about the feasibility, survival, indications, complications, and potential candidates for civilian pre-hospital REBOA. METHODS: A literature search was conducted using Medline, EMBASE, LILACS and Web of Science databases. Primary outcome variables included overall survival and feasibility. Secondary outcome variables included complications and potential candidates for endovascular occlusion. RESULTS: The search identified 8 articles. Five studies described the use of REBOA in pre-hospital settings, reporting a total of 47 patients in whom the procedure was attempted. Pre-hospital REBOA was feasible in 68-100% of trauma patients and 100% of non-traumatic patients with cardiac arrest. Survival rates and complications varied widely. Pre-hospital REBOA requires a coordinated and integrated emergency health care system with a well-trained and equipped team. The remaining three studies performed a retrospective analysis identifying 784 potential REBOA candidates. CONCLUSIONS: Pre-hospital REBOA could be a feasible intervention for a significant portion of severely ill patients in the civilian setting. However, the evidence is limited. The impact of pre-hospital REBOA should be assessed in future studies.

PURPOSE: The purpose of this study was to examine the association of REBOA and mortality in a group of patients with penetrating trauma to the torso, treated in a level-I trauma center from Colombia. METHODS: In a retrospective cohort study, patients with penetrating trauma, requiring emergency surgery, and treated between 2014 and 2018, were included. The decision to use or not use REBOA during emergent surgery was based on individual surgeon's opinion. A propensity score (PS) was calculated after adjusting for age, clinical signs on admission (systolic blood pressure, cardiac rate, Glasgow coma scale), severe trauma in thorax and abdomen, and the presence of non-compressive torso hemorrhage. Subsequently, logistic regression for mortality was adjusted for the number of red blood cells (RBC) transfused within the first six hours after admission, injury severity score (ISS), and quintiles of PS. RESULTS: We included 345 patients; 28 of them (8.1%) were treated with REBOA. Crude mortality rates were 17.9% (5 patients) in REBOA group and 15.3% (48 patients) in control group (p = 0.7). After controlling for RBC transfused, ISS, and the PS, the odds of death in REBOA group was 78% lower than that in the control group (odds ratio [OR] 0.20, 95% confidence interval [95%CI] 0.05-0.77, p = 0.01). CONCLUSION: We found that, when compared to no REBOA use, patients treated with REBOA had lower risk-adjusted odds of mortality. These findings should be interpreted with caution and confirmed in future comparative studies, if possible.

PURPOSE: Although Damage Control Thoracic Surgery (DCTS) has become a provocative alternative to treat patients with chest injuries who are critically ill and physiologically depleted, the management approaches of chest-packing and the measurement of clinically relevant outcomes are not well established. In this paper, we systematically reviewed the available knowledge and evidence about intra-thoracic packing during DCTS for trauma patients. We furthermore inform on the management approaches, surgical strategies, and mortality associated with this intervention. METHODS: We identified articles in MEDLINE and SCOPUS. We reviewed all studies that included trauma patients with chest injuries and managed with intrathoracic packing during DCTS. Studies were eligible if the use of intrathoracic packing in trauma populations was reported. RESULTS: We identified 14 studies with a total of 211 patients. Overall, intrathoracic packing was used in 131 trauma patients. Packing was most commonly used to arrest persistent coagulopathic bleeding or oozing either from raw surfaces or repaired structures and in conjunction with other operative techniques. Pneumonectomy was a deadly intervention; however, one study reported survivors when pneumonectomy was deferred. CONCLUSION: Packing is a feasible, reliable and potentially effective complementary method for hemorrhage control. Therefore, we recommend that packing can be used liberally as a complement to rapid lung-sparing techniques.

BACKGROUND: We performed a systematic review (SR) and meta-analysis (MA) to determine the diagnostic accuracy of chest ultrasound (US) compared with a pericardial window (PW) for the diagnosis of occult penetrating cardiac injuries in hemodynamically stable patients with penetrating thoracic trauma. METHODS: A literature search in five databases identified relevant articles for inclusion in this SR and MA. Studies were eligible if they evaluated the diagnostic accuracy of chest US, compared with a PW, for the diagnosis of occult penetrating cardiac injuries in hemodynamically stable patients presenting with penetrating thoracic trauma. Two investigators independently assessed articles for inclusion and exclusion criteria and selected studies for final analysis. Methodological quality was evaluated using Quality Assessment of Diagnostic Accuracy Studies-2. We performed a MA of binary diagnostic test accuracy within the bivariate mixed-effects logistic regression modeling framework. RESULTS: We included five studies in our SR and MA. These studies included a total of 556 trauma patients. The MA found that, compared with PW, the US was 79% sensitive and 92% specific for detecting occult penetrating cardiac injuries in hemodynamically stable patients. The presence of a concomitant left hemothorax was frequent in patients with false-negative results. CONCLUSION: This SR and MA found that, compared with PW, US was 79% sensitive and 92% specific for detecting occult penetrating cardiac injuries in hemodynamically stable patients with penetrating thoracic trauma. Caution interpretation of pericardial US results is suggested in the presence of left hemothorax. In these cases, a second diagnostic test should be performed. LEVEL OF EVIDENCE: Systematic Review and Meta-analysis, level II.

In designing and implementing a peer support writing group for junior researchers at our home institution, we saw an opportunity to advance the understanding of this intervention as a valuable tool for future physician-scientists. We, therefore, performed a scoping literature review of the available literature on peer support writing groups in clinical disciplines to learn what has been described about this topic. We paid specific attention to the characteristics, implementation, and impact of these groups on the academic development of medical/healthcare scientists. We performed a scoping literature review following the conceptual framework proposed by Arksey and O'Malley. We included studies describing the characteristics, implementation, and impact/effects of peer support writing groups in clinical disciplines. All the information extracted was summarized descriptively to chart the available literature on peer support writing groups in clinical disciplines. We identified a total of 369 articles, of which six were finally included. The absolute number of papers published increased considerably after the participation in the peer support writing groups. The subjective comments of the participating individuals highlighted the positive effects of these groups on the academic productivity of attendees. Available information shows a significant increase in the absolute number of publications and a positive perception between individuals participating in peer support writing groups. Stakeholders should implement this strategy in their home academic institutions.
ABSTRACT
BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) could provide a survival benefit to severely injured patients as it may improve their initial ability to survive the hemorrhagic shock. Although the evidence supporting the use of REBOA is not conclusive, its use has expanded worldwide. We aim to compare the management approaches and clinical outcomes of trauma patients treated with REBOA according to the countries' income based on the World Bank Country and Lending Groups. METHODS: We used data from the AORTA (USA) and the ABOTrauma (multinational) registries. Patients were stratified into two groups: (1) high-income countries (HICs) and (2) low-to-middle income countries (LMICs). Propensity score matching extracted 1:1 matched pairs of subjects who were from an LMIC or a HIC based on age, gender, the presence of pupillary response on admission, impeding hypotension (SBP ≤ 80), trauma mechanism, ISS, the necessity of CPR on arrival, the location of REBOA insertion (emergency room or operating room) and the amount of PRBCs transfused in the first 24 h. Logistic regression (LR) was used to examine the association of LMICs and mortality. RESULTS: A total of 817 trauma patients from 14 countries were included. Blind percutaneous approach and surgical cutdown were the preferred means of femoral cannulation in HICs and LIMCs, respectively. Patients from LMICs had a significantly higher occurrence of MODS and respiratory failure. LR showed no differences in mortality for LMICs when compared to HICs; neither in the non-matched cohort (OR = 0.63; 95% CI: 0.361.09; p = 0.1) nor in the matched cohort (OR = 1.45; 95% CI: 0.633,33; p = 0.3). CONCLUSION: There is considerable variation in the management practices of REBOA and the outcomes associated with this intervention between HICs and LMICs. Although we found significant differences in multiorgan and respiratory failure rates, there were no differences in the risk-adjusted odds of mortality between the groups analyzed. Trauma surgeons practicing REBOA around the world should joint efforts to standardize the practice of this endovascular technology worldwide.
