Objective Antithrombin III (ATIII) deficiency may result from hereditary or acquired reduction in ATIII levels and is associated with an increase in venous thromboembolism (VTE) in the general population. VTE is a potentially preventable complication in the critically ill surgical patients. The objective of this study was to evaluate the relation between ATIII levels and VTE in surgical intensive care unit (SICU) patients.Methods All patients admitted to the SICU from January 2017 to April 2018 who had ATIII levels drawn were included in the study. An ATIII level below 80% of normal was considered low. The rate of VTE during the same admission was compared among patients with normal and low levels of ATIII. Prolonged length of stay (LOS >10 days) and mortality were also measured.Results Of the 227 patients included, 59.9% were male. The median age was 60 years. Overall, 66.9% of patients had low ATIII levels. Trauma patients had a higher rate of normal ATIII levels, whereas those weighing more than 100 kg had a higher rate of low ATIII levels. Patients with low ATIII levels had higher VTE rates compared with those with normal ATIII levels (28.9% vs. 16%, p=0.04). Patients with low ATIII levels also had prolonged LOS (76.3% vs. 60%, p=0.01) and increased mortality (21.7% vs. 6.7%, p

Introduction: During the current pandemic, there has been a paucity of Greek data in terms of recording the general long-term functional status of patients after coronavirus disease 2019 (COVID-19) hospitalizations, as well as very little information regarding rehabilitation services nationwide and their utilization. Objective-design: This is a prospective cohort study, including 92 adults discharged from the Infectious Disease Unit of a third-level hospital in Greece after hospitalization with COVID-19. Demographics and disease severity data was collected upon admission and symptoms at discharge, 4 months and 1 year. Following rating of 12 common symptoms on a Likert scale, quality-of-life data and accessibility to rehabilitation services were compared among the 3 time points. Results: At discharge, the most prevalent complaints were fatigue, exertional dyspnoea and difficulty walking. At 4 months, these 3 remained among the most prevalent symptoms, while pain and memory/loss concentration remained at high numbers as well. Finally, at the 1-year mark, the percentages of patients reporting fatigue, exertional dyspnoea and pain were the highest. At the 4-month follow-up, only 4.3% of the study participants had visited a rehabilitation facility of any kind, whereas at the 1-year mark the percentage rose to 10.9%. Conclusion: A clinically relevant number of participants experienced at least one post-COVID-19 hospitalization symptom. Quality of life was markedly affected by the longer-term effects of the disease. The percentage of people finally attending any kind of rehabilitation service was poor. With thousands more being infected and needing hospitalization nationwide daily, the need for the inclusion of relevant rehabilitation programmes in the Greek healthcare system appears imminent. LAY ABSTRACT For this research paper, we studied 92 adults discharged from the Infectious Disease Unit of a third-level hospital after hospitalization with COVID-19, examining their quality of life and accessibility to rehabilitation services among 3 time points: discharge, 4 months and 1 year afterwards. At discharge, the most prevalent complaints were fatigue, exertional dyspnoea and difficulty walking. At 4 months, these 3 remained among the most prevalent symptoms, while pain and memory/loss concentration remained at high numbers as well. Finally, at the 1-year mark, the percentages of patients reporting fatigue, exertional dyspnoea and pain were the highest. Quality of life was markedly affected by the longer-term effects of the disease. The percentage of people finally attending any kind of rehabilitation service was poor. Without a doubt, the need for inclusion of rehabilitation programmes in the healthcare systems is imminent in order to face the continued pandemic challenge.

Objectives The goal of this study was to explore the incidence of overtransfusion in trauma patients requiring massive transfusion protocol (MTP) activation and identify modifiable risk factors. We hypothesized that overtransfusion is common after MTP activation.Methods Patients admitted to a level I trauma center from July 2016 to December 2019 and who required MTP activation were selected. The primary outcome was overtransfusion, defined as a hemoglobin (Hg) ≥11 g/dL at 24 hours (±2 hours). A Cox regression model was used to identify independent risk factors for overtransfusion.Results 140 patients met inclusion criteria. The median age was 39.0 years, with the majority (74.3%) being male. The median (IQR) Injury Severity Score (ISS) was 24.0 (58.0) and 38.4% had a penetrating mechanism. The median (IQR) admission Hg was 12.6 (11.7) g/dL. Overall, 71.4% of patients were overtransfused by the conclusion of MTP, 43.6% 24 hours later, and 29.5% at discharge. Overtransfusion did not correlate with the number of units of blood transfused nor with the duration of MTP. Overtransfused patients at 24 hours after the conclusion of MTP were significantly more likely to present with a penetrating injury (52.5% vs. 27.3%, p=0.003) and have a significantly lower ISS (median (IQR) 18.5 (44.0) vs. 26.0 (58.0), p=0.035.) In a Cox regression model, penetrating mechanism (adjusted HR (AHR): 2.93; adjusted p=0.004) and admission base excess (BE) (AHR: 1.15; adjusted p=0.001) were the only variables independently associated with overtransfusion.Conclusions Overtransfusion of trauma patients requiring MTP activation is highly common, leading to overutilization of a limited resource. Penetrating trauma and BE may be modifiable risk factors that can help limit overtransfusion. Overtransfusion should be tracked as a data point by blood banks and trauma centers and be further studied as a potential quality metric for the resuscitation of massively transfused trauma patients.Level of evidence III.

Introduction: The role of robotic surgery in the nonelective setting remains poorly defined. Accessibility, patient acuity, and high turn-over may limit its applicability and utilization. The goal is to characterize the role of robotic cholecystectomy (CCY) in a busy acute care surgery (ACS) practice at a quaternary medical center, and compare surgical outcomes and resource utilization between robotic and laparoscopic CCY. Methods: Adult patients who underwent robotic (Da Vinci Xi) or laparoscopic CCY between 01/2021-12/2022 by an ACS attending within 1 week of admission were included. Primary outcomes included time from admission to surgery, off hour (weekend and 6p-6a) cases, operation time, and hospital costs, to reflect "feasibility" of robotic compared to laparoscopic CCY. Secondary outcomes encompassed surgery-related outcomes and complications. Results: The proportion of robotic CCY increased from 5% to 32% within 2 years. In total 361 laparoscopic and 89 robotic CCY were performed. Demographics and gallbladder disease severity were similar. Feasibility measures--operation time, case start time, time from admission to surgery, proportion of off-hour cases, and cost--were comparable between robotic and laparoscopic CCY. There were no differences in surgical complications, common bile duct injury, readmission, or mortality. Conversion to open surgery occurred more often in laparoscopic cases (5% vs 0%, P = .02, OR = 1.05). Discussion: Robotic CCY is associated with fewer open conversions and otherwise similar outcomes compared to laparoscopic CCY in the non-elective setting. Incorporation of robotic CCY in a busy ACS practice model is feasible with available resources. [ABSTRACT FROM AUTHOR]

Introduction: Selective nonoperative management of neck injuries from penetrating mechanism has become an acceptable management strategy. We herein characterize current management strategies of cervical pharyngoesophageal injuries implemented by trauma surgeons in the United States. Methods: The National Trauma Data Bank datasets 2007–2011 were queried for penetrating pharyngeal and/or cervical esophageal injuries. Subjects surviving 24 hours or more were analyzed based on whether a surgical exploration was pursued and by gunshot versus stabbing mechanism. Results: In all, 1,256 patients were identified, representing 6% of all penetrating neck injuries during the study period. The majority (84%) were male, with a median age of 27 years. Injury severity was high (median score of 14). Compared to stabbing victims, gunshot patients were more likely to have associated cervical spine (24% vs. 1%, p

The enzymatic activity of APOBEC3B (A3B) has been implicated as a prime source of mutagenesis in head and neck squamous cell carcinoma (HNSCC). The expression of Protein Kinase C α (PKCα) and Nuclear Factor-κΒ p65 (NF-κΒ p65) has been linked to the activation of the classical and the non-canonical NF-κB signaling pathways, respectively, both of which have been shown to lead to the upregulation of A3B. Accordingly, the aim of the present study was to evaluate the expression of PKCα, NF-κΒ p65 and A3B in non-HPV related oral and oropharyngeal squamous cell carcinomas (SCC), by means of immunohistochemistry and in silico methods. PKCα was expressed in 29/36 (80%) cases of oral and oropharyngeal SCCs, with 25 (69%) cases showing a PKCα+/A3B+ phenotype and only 6/36 (17%) cases showing a PKCα-/A3B+ phenotype. Εxpression of NF-κB p65 was seen in 33/35 (94%) cases of oral and oropharyngeal SCCs, with 30/35 (86%) cases showing an NF-κB p65+/A3B+ phenotype and only 2/35 (6%) cases showing an NF-κB p65-/A3B+ phenotype. In addition, mRNA expression analysis, using the UALCAN database, revealed strong expression of all three genes. These findings indicate that the expression of A3B is associated with PKCα/NF-κB p65 expression and suggest a potential role for the PKC/NF-κB signaling pathway in the development of oral and oropharyngeal cancer.

Introduction Infection control in patients with perforated peptic ulcers (PPU) commonly includes empiric antifungals (AF). We investigated the variation in the use of empiric AF and explored the association between their use and the subsequent development of organ space infection (OSI).Methods This was a secondary analysis of a multicenter, case–control study of patients treated for PPU at nine institutions between 2011 and 2018. Microbiology and utilization of empiric AF, defined as AF administered within 24 hours from the index surgery, were recorded. Patients who received empiric AF were compared with those who did not. The primary outcome was OSI and secondary outcome was OSI with growth of Candida spp. A logistic regression was used to adjust for differences between the two cohorts.Results A total of 554 patients underwent a surgical procedure for PPU and had available timing of AF administration. The median age was 57 years and 61% were male. Laparoscopy was used in 24% and omental patch was the most common procedure performed (78%). Overall, 239 (43%) received empiric AF. There was a large variation in the use of empiric AF among participating centers, ranging from 25% to 68%. The overall incidence of OSI was 14% (77/554) and was similar for patients who did or did not receive empiric AF. The adjusted OR for development of OSI for patients who received empiric AF was 1.04 (95% CI 0.64 to 1.70), adjusted p=0.86. The overall incidence of OSI with growth of Candida spp was 5% and was similar for both groups (adjusted OR 1.29, 95% CI 0.59 to 2.84, adjusted p=0.53).Conclusion For patients undergoing surgery for PPU, the use of empiric AF did not yield any significant clinical advantage in preventing OSI, even those due to Candida spp. Use of empiric AF in this setting is unnecessary.Study type Original article, case series.Level of evidence III.

Background: International rotations with hands-on experience are commonly cited as a potential supplement to the current experience of surgical trainees in trauma; however, quantification of this experience remains unclear. Methods: A link to an online survey was distributed by electronic mail to physicians who rotated for any period of time at the Trauma Unit of the Groote-Shuur Hospital of the University of Cape Town from January 1, 2006, to December 2016. Results: Of 160 participants, 75 (47%) completed the survey. A high proportion (45%) had performed less than 25 trauma-related surgical procedures during their previous training. Most (56%) performed ≥10 trauma laparotomies and sternotomies/thoracotomies during their rotation, whereas 43% performed ≥5 vascular procedures. The level of perceived confidence in managing trauma patients increased significantly from a median of 3/10 to 7/10 (P < .05). Conclusion: Rotations at large-volume trauma centers abroad offer the opportunity for a hands-on operative experience and may enhance the confidence of surgical trainees. Further standardization of these opportunities may result in a larger-scale participation of graduate residents and fellows.

Background: Although ejections from motor vehicles are considered a marker of a significant mechanism and a predictor of severe injuries and mortality, scant recent data exist to validate these outcomes. This study investigates whether ejections increase the mortality risk following a motor vehicle crash using data that reflect the introduction of new vehicles to the streets of a large city in the United States. Methods: The Trauma and Emergency Medicine Information System of Los Angeles County was queried for patients ≥16 years old admitted following a motor vehicle crash between 2002 and 2012. Ejected patients were compared to nonejected. Primary outcome was mortality. A logistic regression model was used to identify predictors of mortality and severe trauma. Results: A total of 9,742 (6.8%) met inclusion criteria. Of these, 449 (4.6%) were ejected; 368 (82.0%) were passengers and 81 (18.0%) were drivers. The rate of ejection decreased linearly (6.1% in 2002 to 3.4% in 2012). Compared to nonejected patients, ejected patients were more likely to require intensive care unit admission (43.7% vs 22.1%, P 25) (24.2% vs 7.3%, P 25) with adjusted odds ratio of 2.48 (P
