RESUMO

INTRODUCTION: Adipose-derived stem cells (ASCs) are multipotent stem cells capable of differentiating into many cell lineages. They play an important role in wound healing by secreting cytokines. Prior studies have demonstrated the presence of proinflammatory cytokines in burn wounds. However, no studies have been performed evaluating the cytokines released by burn wounds with infections. We hypothesized that there is an alteration in the paracrine factors secreted by ASCs in burn wounds with concomitant infections. METHODS: Adipose tissue was collected from patients with burn injuries at their index operation. ASCs were extracted and grown under standard tissue culture techniques. The supernatant was extracted. Cytokine analyses were performed with multiplex assays. Infection was determined using a burn sepsis protocol. The cytokine profiles of the two groups were compared using a Mann-Whitney U test. RESULTS: Sixteen patients were enrolled in the study, 50% with bacterial infection (n = 8). There was no significant difference in the baseline demographics of the two groups (P > 0.05). There were significantly lower concentrations of interleukin 13 and interferon gamma (P < 0.05) in burn patients with concomitant infections. CONCLUSIONS: ASCs are critical to burn wound healing. This study demonstrated diminished production of interleukin 13, an immunoregulatory cytokine involved in the antiinflammatory pathway by downregulating macrophage activity. This study also demonstrated significantly lower levels of interferon gamma in patient with burns and concomitant infection. This cytokine is crucial for antimicrobial defenses.

RESUMO

INTRODUCTION: One of the significant complications of operative liver trauma is intra-abdominal abscesses (IAA). The objective of this study was to determine risk factors associated with postoperative IAA in surgical patients with major operative liver trauma. METHODS: A retrospective multi-institutional study was performed at 13 Level 1 and Level 2 trauma centers from 2012 to 2021. Adult patients with major liver trauma (grade 3 and higher) requiring operative management were enrolled. Univariate and multivariate analyses were performed. RESULTS: Three hundred seventy-two patients were included with 21.2% (n = 79/372) developing an IAA. No difference was found for age, gender, injury severity score, liver injury grade, and liver resections in patients between the groups (P > 0.05). Penetrating mechanism of injury (odds ratio (OR) 3.42, 95% confidence interval (CI) 1.54-7.57, P = 0.02), intraoperative massive transfusion protocol (OR 2.43, 95% CI 1.23-4.79, P = 0.01), biloma/bile leak (OR 2.14, 95% CI 1.01-4.53, P = 0.04), hospital length of stay (OR 1.04, 95% CI 1.02-1.06, P < 0.001), and additional intra-abdominal injuries (OR 2.27, 95% CI 1.09-4.72, P = 0.03) were independent risk factors for IAA. Intra-abdominal drains, damage control laparotomy, total units of packed red blood cells, number of days with an open abdomen, total abdominal surgeries, and blood loss during surgery were not found to be associated with a higher risk of IAA. CONCLUSIONS: Patients with penetrating trauma, massive transfusion protocol activation, longer hospital length of stay, and injuries to other intra-abdominal organs were at higher risk for the development of an IAA following operative liver trauma. Results from this study could help to refine existing guidelines for managing complex operative traumatic liver injuries.

RESUMO

INTRODUCTION: The reported rate of postoperative bile leak is variable between 3 and 33%. Recent data would suggest a minimally invasive approach to liver surgery has decreased this incidence. METHODS: This multi-institutional case-control study utilized databases from three high-volume surgeons. All consecutive open and minimally invasive liver resection cases were analyzed in a propensity score-adjusted multivariable regression. A p value < 0.05 was considered significant. RESULTS: In 1388 consecutive liver resections, the average age was 56.9 ± 14.0 years, 730 (52.59%) were male gender, and 599 (43.16%) underwent minimally invasive liver resection. Thirty-nine (2.81%) in the series were identified with post-resection bile duct leaks. Leaks were associated with major resections and increased blood loss (p < 0.05). Propensity score-adjusted multivariable regression identified minimally invasive liver resection significantly and independently reduced the odds of bile duct leak (OR 0.48, p = 0.046) even controlling for BMI, ASA, cirrhosis, major resection, and resection year. CONCLUSIONS: Our data suggest the incidence of bile leaks in a large-volume center series is far less than previously reported and that a minimally invasive approach to liver resection reduces the incidence of postoperative bile leak.

RESUMO

BACKGROUND: Racial disparity in access to liver transplantation among African Americans (AA) compared to Caucasians (CA) has been well described. The aim of this investigation was to examine the presentation of AA liver transplant recipients in a socioeconomically challenged region. METHODS: 680 adult liver transplant candidates and 233 resultant recipients between 2007 and 2015 were analyzed using univariate and multivariate analyses to evaluate factors significant for transplantation. RESULTS: Percentages of wait list patients transplanted were similar between CA and AA (34.9% vs. 32.2%, p = 0.5205). AA were younger (50.4 ± 1.8 vs. 56.3 ± 0.7 yrs, p = 0.0003) with higher average MELD scores (22.9 ± 1.6 vs. 19.4 ± 0.7, p = 0.0230). Overall patient mortality was similar (AA 22.7% vs. CA 26.3%, p = 0.5931). A multiple linear regression showed that male gender was strongly associated with transplantation. CONCLUSIONS: Equal access to liver transplantation remains challenging for racial minorities. At our institution, AA were accepted and transplanted at an equivalent rate as CA despite a higher AA population, HCV rate and diagnosed HCC. AA were younger and sicker at the time of transplant, but overall had similar outcomes compared to CA. Our study highlights the need for studies to delineate the underpinnings of disparity in transplantation access.

RESUMO

BACKGROUND: We present the unusual complication of peritoneal dialysis (PD) catheter dysfunction in a patient who developed a retroperitoneal hematoma following an endoscopic procedure and review the existing literature regarding this rare complication. CASE REPORT: A 60-year-old man with end stage renal disease presented with PD catheter dysfunction. Computed tomography scan of his abdomen showed a large left retroperitoneal hematoma. He underwent a diagnostic laparoscopy and PD catheter revision. The retroperitoneal hematoma had ruptured into the peritoneum with clots clogging the catheter. Clots were evacuated and the catheter was flushed. He restarted on low volume PD three days after surgery and increased to full volume within a week with no further issues. CONCLUSIONS: This case summarizes the very unusual complication of a retroperitoneal bleed from an endoscopic procedure that manifested as PD catheter dysfunction. The increasing utilization of PD catheters requires that surgeons remain aware of potential complications.

RESUMO

OBJECTIVES: Racial disparity as a barrier to successful outcomes in renal transplants for African Americans has been well described. Numerous unsuccessful attempts have been made to identify specific immunologic and socioeconomic factors. The objective of our study was to determine whether alemtuzumab (AL) induction abolishes this discrepancy and improves allograft survival in African American recipients. METHODS: A retrospective chart review of consecutive adult renal transplants was conducted between 2006 and 2014. Kaplan-Meier analysis and hazard ratios were calculated for the African Americans (AA) and white groups. Multiple linear regressions were performed to assess independent variables (race, retransplant, sex, donor type, induction agent) on allograft survival. RESULTS: A significant difference in allograft survival was identified between whites (n = 272) and AA (n = 445), with AA experiencing more graft losses (18.2% vs 12.1%, P = 0.0351). Induction with AL improved outcomes in all transplant recipients. Multiple linear regression identified that the strongest predictor of allograft failure was induction without AL (P < 0.0001). The data for a subset analysis matched for follow-up length demonstrated that whites compared with AA (n = 157, 67 whites and 90 AA) had lower rates of allograft failure in the absence of AL induction (14.9% vs 44.4%, P = 0.0156, hazard ratio = 2.077). In contrast, AL induction (n = 275, 105 whites and 170 AA) eliminated the racial disparity in allograft failure (5.7% vs 9.4%, P = 0.8248, hazard ratio = 1.504). CONCLUSIONS: This is the first study to describe the effects of AL induction therapy on AA renal transplant recipients beyond the first posttransplant year. Our early results suggest that AL induction therapy abolishes the disparity in renal allograft failure.

RESUMO

Aim: Mesenchymal stem cells (MSCs) are pluripotent cells with significant therapeutic potential. The objective of this study was to examine the inflammatory profile of MSCs cultured under different conditions. Methods: MSCs were cultured by three strategies: seeding on an extracellular matrix (ECM), spheroids in static culture and spheroids in a bioreactor. Paracrine factors and CD206, a marker of M2 macrophage phenotype, were measured. Results: MSCs grown as spheroids in a bioreactor produced more IL-6 and IL-8 (p < 0.05). Supernatant collected from spheroids under both culture conditions increased the M2 macrophage phenotype almost twofold. Conclusion: Results indicate that the inflammatory profile of the supernatant collected from MSCs can be modified through culture conditions which has impacts for the future of regenerative medicine.

RESUMO

PURPOSE: To describe the experience of a single level 1 trauma center in the management of blunt splenic injuries (BSI). METHODS: This is a retrospective study with Institutional Review Board approval. The medical records of 450 patients with BSI treated between January 2016 and December 2022 were reviewed. Seventy-two patients were treated with splenic artery embolization (SAE), met the study criteria, and were eligible for data analysis. Spleen injuries were graded in accordance with the American Association for the Surgery of Trauma Organ Injury Scale. Univariate data analysis was performed, with P < 0.05 considered statistically significant. RESULTS: The splenic salvage rate was 90.3% (n = 65/72). Baseline demographics were similar between the groups (P > 0.05). Distal embolization with Gelfoam® had similar rates of splenic salvage to proximal embolization with coils (90% vs. 94.1%, P > 0.05). There was no significant difference in the rate of splenic infarction between distal embolization with Gelfoam® (20%, 4/20) and proximal embolization with coils (17.6%, 3/17) (P > 0.05). There was no significant difference in procedure length (68 vs. 75.8 min) or splenic salvage rate (88.5% vs. 92.1%) between proximal and distal embolization (P > 0.05). There was no significant difference in procedure length (69.1 vs. 73.6 min) or splenic salvage rate (93.1% vs. 86.4%) between Gelfoam® and coil embolization (P > 0.05). Combined proximal and distal embolization was associated with a higher rate of splenic abscess formation (25%, 2/8) when compared with proximal (0%, 0/26) or distal (0%, 0/38) embolization alone (P = 0.0003). The rate of asymptomatic and symptomatic splenic infarction was significantly higher in patients embolized at combined proximal and distal locations (P = 0.04, P = 0.01). CONCLUSION: The endovascular management of BSI is safe and effective. The overall splenic salvage rate was 90.3%. Distal embolization with Gelfoam® was not associated with higher rates of splenic infarction when compared with proximal embolization with coils. Combined proximal and distal embolization was associated with a higher incidence of splenic infarction and splenic abscess formation. CLINICAL SIGNIFICANCE: Distal splenic embolization with Gelfoam® is safe and may be beneficial in the setting of blunt splenic trauma.

RESUMO

Tension pneumothorax (TPT) identified in the prehospital setting requires prehospital needle decompression (PHND). This study aimed to evaluate complications from PHND when it was performed without meeting clinical criteria. A retrospective review was performed of patients undergoing (PHND) from 2016 through 2022 at a level 1 trauma center. Patient data who received PHND were reviewed. Of 115 patients, 85 did not meet at least one clinical criterion for PHND. The majority of patients in this cohort 76 (89%) required a chest tube and 22 (25%) had an iatrogenic pneumothorax from PHND. 5 patients (6%) were admitted due to iatrogenic PHND. Two vascular injuries in this population were directly due to PHND and required emergency operative repair. This study shows the negative consequences of PHND when performed without clear indications. Several patients underwent unnecessary procedures with significant clinical consequences.

RESUMO

Pyoderma gangrenosum (PG) is a rare, chronic, ulcerative disease characterized by non-healing wounds that worsen with debridement, a phenomenon called pathergy. No consensus regarding pathogenesis, diagnosis, or treatment exists for PG. A previous pilot study using dehydrated human amniotic/chorionic membrane (dHACM), following excisional debridement, augmented PG wound healing and allowed for subsequent wound closure through split-thickness skin grafting (STSG). In this clinical trial (NCT05120726), four patients with an established PG diagnosis were enrolled to undergo treatment with dHACM and characterize the pre- and post-treatment transcriptome profiles. RNA sequencing was used to isolate the total RNA from specimens. Genes of particular interest were quantified through real-time quantitative reverse transcription polymerase chain reaction. We observed varied changes to the local expression of inflammatory response, positive regulators of cellular proliferation, and extracellular matrix disassembly cytokines. All PG wounds produced granulation tissue following treatment and were closed using split-thickness skin grafts.

RESUMO

Empyema resulting as a complication of penetrating diaphragmatic injuries is a subject that requires further investigation, and the aim of this study was to determine the risk factors associated with empyema in patients with penetrating trauma. Consecutive adult trauma patients from a level 1 trauma center were searched for penetrating diaphragm injuries. Data were collected on patient demographics, pre-existing conditions, injury type and severity, hospital interventions, in-hospital complications, and outcomes. Patients were stratified by empyema formation and univariant analyses were performed. 164 patients were identified, and 17 patients (10.4%) developed empyema. Empyema was associated with visible abdominal contamination (35.3% vs 15%, P = .04), thoracotomy (35.5% vs 13.6%, P = .03), pneumonia (41.2% vs 14.3%, P = .01), sepsis (35.3% vs 8.8%, P = .006), increased hospital length of stay (25.5 vs 10.1 days, p =<.001), increased intensive care unit length of stay (9.6 vs 4.3 days, P = .01), and decreased in-hospital mortality (0% vs 20.4%, P = .04).

RESUMO

INTRODUCTION: The United States has one of the highest rates of gun violence and mass shootings. Timely medical attention in such events is critical. The objective of this study was to assess geographic disparities in mass shootings and access to trauma centers. METHODS: Data for all Level I and II trauma centers were extracted from the American College of Surgeons and the Trauma Center Association of America registries. Mass shooting event data (4+ individuals shot at a single event) were taken from the Gun Violence Archive between 2014 and 2018. RESULTS: A total of 564 trauma centers and 1672 mass shootings were included. Ratios of the number of mass shootings vs trauma centers per state ranged from 0 to 11.0 mass shootings per trauma center. States with the greatest disparity (highest ratio) included Louisiana and New Mexico. CONCLUSION: States in the southern regions of the US experience the greatest disparity due to a high burden of mass shootings with less access to trauma centers. Interventions are needed to increase access to trauma care and reduce mass shootings in these medically underserved areas.

RESUMO

Traumatic abdominal wall hernias are a rare complication of high energy blunt trauma. There exist several studies evaluating and outlining potential management options but still no generalized consensus on management. This series was meant to evaluate the diagnosis and management of traumatic abdominal wall hernias. A prospectively maintained database was used to identify patients with TAWH from 2021 to 2022. The primary outcome was operative management. Secondary outcomes included: time to diagnosis and post-operative outcomes. Of the 19 patients in this case series, 100% (n = 19/19) were secondary to blunt trauma with a mean ISS of 21. Exploratory laparotomy was performed in 17 cases. 14 cases had concomitant traumatic injuries to visceral structures. Complications were found in nearly half of the patients with 3 experiencing wound dehiscence. Future studies should be aimed at standardizing management approach taking into account nature of the mechanism and concomitant injuries.

RESUMO

BACKGROUND: The standard for managing traumatic pneumothorax (PTX), hemothorax (HTX), and hemopneumothorax (HPTX) has historically been large-bore (LB) chest tubes (>20-Fr). Previous studies have shown equal efficacy of small-bore (SB) chest tubes (≤19-Fr) in draining PTX and HTX/HPTX. This study aimed to evaluate provider practice patterns, treatment efficacy, and complications related to the selection of chest tube sizes for patients with thoracic trauma. METHODS: A retrospective chart review was performed on adult patients who underwent tube thoracostomy for traumatic PTX, HTX, or HPTX at a Level 1 Trauma Center from January 2016 to December 2021. Comparison was made between SB and LB thoracostomy tubes. The primary outcome was indication for chest tube placement based on injury pattern. Secondary outcomes included retained hemothorax, insertion-related complications, and duration of chest tube placement. Univariate and multivariate analyses were performed. RESULTS: Three hundred and forty-one patients were included and 297 (87.1%) received LB tubes. No significant differences were found between the groups concerning tube failure and insertion-related complications. LB tubes were more frequently placed in patients with penetrating MOI, higher average ISS, and higher average thoracic AIS. Patients who received LB chest tubes experienced a higher incidence of retained HTX. DISCUSSION: In patients with thoracic trauma, both SB and LB chest tubes may be used for treatment. SB tubes are typically placed in nonemergent situations, and there is apparent provider bias for LB tubes. A future randomized clinical trial is needed to provide additional data on the usage of SB tubes in emergent situations.

RESUMO

BACKGROUND: With an ongoing demand for transplantable organs, optimization of donor management protocols, specifically in trauma populations, is important for obtaining a high yield of viable organs per patient. Endocrine management of brain-dead potential organ donors (BPODs) is controversial, leading to heterogeneous clinical management approaches. Previous studies have shown that when levothyroxine was combined with other treatments, including steroids, vasopressin, and insulin, BPODs had better organ recovery and survival outcomes were increased for transplant recipients. AIM: To determine if levothyroxine use in combination with steroids in BPODs increased the number of organs donated in trauma patients. METHODS: A retrospective review of adult BPODs from a single level 1 trauma center over ten years was performed. Exclusion criteria included patients who were not solid organ donors, patients who were not declared brain dead (donation after circulatory death), and patients who did not receive steroids in their hospital course. Levothyroxine and steroid administration, the number of organs donated, the types of organs donated, and demographic information were recorded. Univariate analyses were performed with P < 0.05 considered to be statistically significant. RESULTS: A total of 88 patients met inclusion criteria, 69 (78%) of whom received levothyroxine and steroids (ST/LT group) vs 19 (22%) receiving steroids without levothyroxine (ST group). No differences were observed between the groups for gender, race, pertinent injury factors, age, or other hormone therapies used (P > 0.05). In the ST/LT group, 68.1% (n = 47) donated a high yield (3-5) of organ types per donor compared to 42.1% (n = 8) in the ST group (P = 0.038). There was no difference in the total number of organ types donated between the groups (P = 0.068). CONCLUSION: This study suggests that combining levothyroxine and steroid administration increases high-yield organ donation per donor in BPODs in the trauma patient population. Limitations to this study include the retrospective design and the relatively small number of organ donors who met inclusion criteria. This study is unique in that it mitigates steroid administration as a confounding variable and focuses specifically on the adjunctive use of levothyroxine.

RESUMO

BACKGROUND: Leak following surgical repair of traumatic duodenal injuries results in prolonged hospitalization and oftentimes nil per os(NPO) treatment. Parenteral nutrition(PN) has known morbidity; however, duodenal leak(DL) patients often have complex injuries and hospital courses resulting in barriers to enteral nutrition(EN). We hypothesized EN alone would be associated with 1)shorter duration until leak closure and 2)less infectious complications and shorter hospital length of stay(HLOS) compared to PN. METHODS: This was a post-hoc analysis of a retrospective, multicenter study from 35 Level-1 trauma centers, including patients >14 years-old who underwent surgery for duodenal injuries(1/2010-12/2020) and endured post-operative DL. The study compared nutrition strategies: EN vs PN vs EN + PN using Chi-Square and Kruskal-Wallis tests; if significance was found pairwise comparison or Dunn's test were performed. RESULTS: There were 113 patients with DL: 43 EN, 22 PN, and 48 EN + PN. Patients were young(median age 28 years-old) males(83.2%) with penetrating injuries(81.4%). There was no difference in injury severity or critical illness among the groups, however there were more pancreatic injuries among PN groups. EN patients had less days NPO compared to both PN groups(12 days[IQR23] vs 40[54] vs 33[32],p = <0.001). Time until leak closure was less in EN patients when comparing the three groups(7 days[IQR14.5] vs 15[20.5] vs 25.5[55.8],p = 0.008). EN patients had less intra-abdominal abscesses, bacteremia, and days with drains than the PN groups(all p < 0.05). HLOS was shorter among EN patients vs both PN groups(27 days[24] vs 44[62] vs 45[31],p = 0.001). When controlling for predictors of leak, regression analysis demonstrated EN was associated with shorter HLOS(ß -24.9, 95%CI -39.0 to -10.7,p < 0.001). CONCLUSION: EN was associated with a shorter duration until leak closure, less infectious complications, and shorter length of stay. Contrary to some conventional thought, PN was not associated with decreased time until leak closure. We therefore suggest EN should be the preferred choice of nutrition in patients with duodenal leaks whenever feasible. LEVEL OF EVIDENCE: IV.

RESUMO

OBJECTIVES: To evaluate the diagnostic performance of the IOTA (International Ovarian Tumor Analysis group) (clinically oriented three-step strategy for preoperative characterization of ovarian masses when ultrasonography is performed by examiners with different background training and experience. METHODS: A 27-month prospective multicenter cross-sectional study was performed. 36 level II ultrasound examiners contributed in three UK hospitals. Transvaginal ultrasonography was performed using a standardized approach. Step one uses simple descriptors (SD), step two ultrasound simple rules (SR) and step three subjective assessment of ultrasound images (SA) by examiners. The final outcome was findings at surgery and the histological diagnosis of surgically removed masses. RESULTS: 1165 women with adnexal masses underwent transvaginal ultrasonography, 301 had surgery. Prevalence of malignancy was 31% (n=92). SD were able to classify 46% of the masses into benign or malignant (step one), with a sensitivity of 93% and specificity of 97%. Applying SD followed by SR to residual unclassified masses by SD enabled 89% of all masses (n=268) to be classified with a sensitivity 95% of and specificity of 95%. SA was then used to evaluate the rest of the masses. Compared to the risk of malignancy index (RMI), the sensitivity and specificity for the three-step (SD+SR+SA) strategy were 93% (95% CI: 86-97%) and 92% (95% CI: 87-95%) vs. 72% (95% CI: 62-80%) and 95% (95% CI: 91-97%) for RMI, respectively. CONCLUSION: The IOTA three-step strategy shows good test performance on external validation in the hands of ultrasonography examiners with different background training and experience. This performance is considerably better than the RMI.

RESUMO

Automobile collisions with driver side intrusion >12 inches or >18 elsewhere meet criteria for trauma activation. However, vehicle safety features have improved since this inception. We hypothesized vehicle intrusion (VI) alone as mechanism-of-injury (MOI) criteria inadequately predicts trauma center activation. A retrospective, single-center chart review of adult patients involved in motor vehicle collisions presenting to a level 1 trauma center from July 2016 to March 2022 was performed. Patients were divided by MOI criteria: VI vs. multiple MOI criteria. 2940 patients met inclusion criteria. The VI group reported lower injury severity scores (P = 0.004), higher incidence of ED discharge (P = 0.001), lower ICU admissions (P = 0.004), and fewer in-hospital procedures (P = 0.03). Vehicle intrusion was found to have a positive likelihood ratio of 0.889 for predicting trauma center need. According to current guidelines, these results suggest that VI criteria alone may not be an accurate predictor for trauma center transport and require further investigation.
