Utility of an Alpha-1 Adrenergic Agonist in the Management of Chylothorax: A Case Series and Management Algorithm.

Chylothorax is the accumulation of lymphatic fluid (chyle) within the pleural space. There are multiple causes, including traumatic and non-traumatic mechanisms. Trauma can cause disruption of the thoracic duct either by direct damage or indirect crushing or avulsion mechanisms. Non-traumatic causes include infections, inflammatory processes, malignancies, and iatrogenic injury (during surgery or central venous access). The traditional management of traumatic chylothorax has been either a conservative approach, including complete Nil Per Os (NPO), or a low-fat diet with medium-chain triglyceride supplementation with the administration of somatostatin or its analog, octreotide, versus a surgical approach consisting of thoracic duct ligation. Recently a less invasive approach via thoracic duct embolization has gained popularity. There have been a few reports of the successful use of an α 1-adrenergic agonist (midodrine) as an adjunct in the conservative approach. We describe the utility of midodrine in three cases of chylothorax and propose a management algorithm. LEARNING POINTS: The initial diagnosis of chylothorax is based on clinical suspicion and proper imaging.The clinical success of midodrine use as a first-line medical treatment for chylothorax will support the use of midodrine before considering invasive procedures.We propose a management algorithm for patients with chylothorax that will stimulate researchers to conduct prospective studies to assess its efficacy.

Systemic and cerebro-cardiac biomarkers following traumatic brain injury: an interim analysis of randomized controlled clinical trial of early administration of beta blockers.

This is an interim analysis of the Beta-blocker (Propranolol) use in traumatic brain injury (TBI) based on the high-sensitive troponin status (BBTBBT) study. The BBTBBT is an ongoing double-blind placebo-controlled randomized clinical trial with a target sample size of 771 patients with TBI. We sought, after attaining 50% of the sample size, to explore the impact of early administration of beta-blockers (BBs) on the adrenergic surge, pro-inflammatory cytokines, and the TBI biomarkers linked to the status of high-sensitivity troponin T (HsTnT). Patients were stratified based on the severity of TBI using the Glasgow coma scale (GCS) and HsTnT status (positive vs negative) before randomization. Patients with positive HsTnT (non-randomized) received propranolol (Group-1; n = 110), and those with negative test were randomized to receive propranolol (Group-2; n = 129) or placebo (Group-3; n = 111). Propranolol was administered within 24 h of injury for 6 days, guided by the heart rate (> 60 bpm), systolic blood pressure (≥ 100 mmHg), or mean arterial pressure (> 70 mmHg). Luminex and ELISA-based immunoassays were used to quantify the serum levels of pro-inflammatory cytokines (Interleukin (IL)-1ß, IL-6, IL-8, and IL-18), TBI biomarkers [S100B, Neuron-Specific Enolase (NSE), and epinephrine]. Three hundred and fifty patients with comparable age (mean 34.8 ± 9.9 years) and gender were enrolled in the interim analysis. Group 1 had significantly higher baseline levels of IL-6, IL-1B, S100B, lactate, and base deficit than the randomized groups (p = 0.001). Group 1 showed a significant temporal reduction in serum IL-6, IL-1ß, epinephrine, and NSE levels from baseline to 48 h post-injury (p = 0.001). Patients with severe head injuries had higher baseline levels of IL-6, IL-1B, S100B, and HsTnT than mild and moderate TBI (p = 0.01). HsTnT levels significantly correlated with the Injury Severity Score (ISS) (r = 0.275, p = 0.001), GCS (r = - 0.125, p = 0.02), and serum S100B (r = 0.205, p = 0.001). Early Propranolol administration showed a significant reduction in cytokine levels and TBI biomarkers from baseline to 48 h post-injury, particularly among patients with positive HsTnT, indicating the potential role in modulating inflammation post-TBI.Trial registration: ClinicalTrials.gov NCT04508244. It was registered first on 11/08/2020. Recruitment started on 29 December 2020 and is ongoing. The study was partly presented at the 23rd European Congress of Trauma and Emergency Surgery (ECTES), April 28-30, 2024, in Estoril, Lisbon, Portugal.

Complications and failure rate of splenic artery angioembolization following blunt splenic trauma: A systematic review.

BACKGROUND: Over recent decades, splenic angioembolization (SAE) as an adjunct to non-operative management (NOM) has emerged as a prominent intervention for patients with blunt splenic injuries (BSI). SAE improves patient outcomes, salvages the spleen, and averts complications associated with splenectomy. This systematic review aimed to evaluate the failure rate and complications related to SAE in patients with BSI. METHODS: A systematic literature search (PubMed, SCOPUS, and Cochrane Library) focused on studies detailing splenic angioembolization in blunt trauma cases. Articles that fulfilled the predetermined inclusion criteria were included. This review examined the indications, outcomes, failure rate, and complications of SAE. RESULTS: Among 599 identified articles, 33 met the inclusion criteria. These comprised 29 retrospective studies, three prospective studies, and one randomized control trial. The analysis encompassed 25,521 patients admitted with BSI and 3,835 patients who underwent SAE. The overall failure rate of SAE was 5.3 %. Major complications predominantly were rebleeding (4.8 %), infarction (4.6 %), and abscess formation (4 %). Minor complications were fever (18.4 %), pleural effusion (13.1 %), and coil migration (3.9 %). Other complications included splenic atrophy, splenic cyst, hematoma, and access site complications such as splenic/femoral dissection. Overall, post embolization mortality was 0.08 %. CONCLUSION: SAE is a valuable adjunct in managing BSI, with a low failure rate. However, this treatment modality is not without the risk of potentially serious complications.

Mechanical versus manual cardiopulmonary resuscitation (CPR): an umbrella review of contemporary systematic reviews and more.

BACKGROUND: High-quality cardiopulmonary resuscitation (CPR) can restore spontaneous circulation (ROSC) and neurological function and save lives. We conducted an umbrella review, including previously published systematic reviews (SRs), that compared mechanical and manual CPR; after that, we performed a new SR of the original studies that were not included after the last published SR to provide a panoramic view of the existing evidence on the effectiveness of CPR methods. METHODS: PubMed, EMBASE, and Medline were searched, including English in-hospital (IHCA) and out-of-hospital cardiac arrest (OHCA) SRs, and comparing mechanical versus manual CPR. A Measurement Tool to Assess Systematic Reviews (AMSTAR-2) and GRADE were used to assess the quality of included SRs/studies. We included both IHCA and OHCA, which compared mechanical and manual CPR. We analyzed at least one of the outcomes of interest, including ROSC, survival to hospital admission, survival to hospital discharge, 30-day survival, and survival to hospital discharge with good neurological function. Furthermore, subgroup analyses were performed for age, gender, initial rhythm, arrest location, and type of CPR devices. RESULTS: We identified 249 potentially relevant records, of which 238 were excluded. Eleven SRs were analyzed in the Umbrella review (January 2014-March 2022). Furthermore, for a new, additional SR, we identified eight eligible studies (not included in any prior SR) for an in-depth analysis between April 1, 2021, and February 15, 2024. The higher chances of using mechanical CPR for male patients were significantly observed in three studies. Two studies showed that younger patients received more mechanical treatment than older patients. However, studies did not comment on the outcomes based on the patient's gender or age. Most SRs and studies were of low to moderate quality. The pooled findings did not show the superiority of mechanical compared to manual CPR except in a few selected subgroups. CONCLUSIONS: Given the significant heterogeneity and methodological limitations of the included studies and SRs, our findings do not provide definitive evidence to support the superiority of mechanical CPR over manual CPR. However, mechanical CPR can serve better where high-quality manual CPR cannot be performed in selected situations.

Machine learning models predict triage levels, massive transfusion protocol activation, and mortality in trauma utilizing patients hemodynamics on admission.

BACKGROUND: The effective management of trauma patients necessitates efficient triaging, timely activation of Massive Blood Transfusion Protocols (MTP), and accurate prediction of in-hospital outcomes. Machine learning (ML) algorithms have emerged as up-and-coming tools in the domains of optimizing triage decisions, improving intervention strategies, and predicting clinical outcomes, consistently outperforming traditional methodologies. This study aimed to develop, assess, and compare several ML models for the triaging processes, activation of MTP, and mortality prediction. METHODS: In a 10-year retrospective study, the predictive capabilities of seven ML models for trauma patients were systematically assessed using on-admission patients' hemodynamic data. All patient's data were randomly divided into training (80 %) and test (20 %) sets. Employing Python for data preprocessing, feature scaling, and model development, we evaluated K-Nearest Neighbors (KNN), Logistic Regression (LR), Decision Tree (DT), Support Vector Machines (SVM) with RBF kernels, Random Forest (RF), Extreme Gradient Boosting (XGBoost), and Artificial Neural Network (ANN). We employed various imputation techniques and addressed data imbalance through down-sampling, up-sampling, and synthetic minority for the over-sampling technique (SMOTE). Hyperparameter tuning, coupled with 5-fold cross-validation, was performed. The evaluation included essential metrics like sensitivity, specificity, F1 score, accuracy, Area Under the Receiver Operating Curve (AUC ROC), and Area Under the Precision recall Curve (AUC PR), ensuring robust predictive capability. RESULT: This study included 17,390 adult trauma patients; of them, 19.5 % (3385) were triaged at a critical level, 3.8 % (664) required MTP, and 7.7 % (1335) died in the hospital. The model's performance improved using imputation and balancing techniques. The overall models demonstrated notable performance metrics for predicting triage, MTP activation, and mortality with F1 scores of 0.75, 0.42, and 0.79, sensitivities of 0.73, 0.82, and 0.9, and AUC ROC values of 0.89, 0.95 and 0.99 respectively. CONCLUSION: Machine learning, especially RF models, effectively predicted trauma triage, MTP activation, and mortality. Featured critical hemodynamic variables include shock indices, systolic blood pressure, and mean arterial pressure. Therefore, models can do better than individual parameters for the early management and disposition of patients in the ED. Future research should focus on creating sensitive and interpretable models to enhance trauma care.

Presentations and management of hospitalized patients with upper extremity fractures at a level 1 trauma center: a 5-year observational study.

BACKGROUND: Upper extremity injuries (UEIs) are common in the emergency departments, yet they are under-reported in developing countries. This study examined the frequency, injury characteristics, and treatment approaches of upper extremity fractures (UEFs) among hospitalized trauma patients in a nationally representative population. METHODS: We conducted a retrospective, observational study including all the hospitalized patients with UEFs in the only level 1 trauma center in Qatar between July 2015 and August 2020. Comparative analyses were performed according to injury mechanisms, severity, and management approach. RESULTS: A total of 2,023 patients sustained UEIs with an average age of 34.4 ± 12.9 years, and 92% were males. Motor vehicle crashes (MVCs; 42.3%) were the primary cause of shoulder girdle injuries in 48.3% of cases. Fractures of the radius, ulna, and hands occurred in 30.8, 16.5 and 14.5%, respectively. Young adults were more involved in MVCs and motorcycle crashes (MCCs), while pedestrians who were typically older had a higher rate of humerus fractures. Patients with MCCs had a higher rate of clavicle and ulna fractures. Pedestrians were at risk of serious injuries, with a higher mean injury severity score and lower Glasgow Coma Scale. CONCLUSION: Most UEFs patients were young males and mainly affected by MVCs. Shoulder girdle, particularly clavicle and scapula/glenoid fractures, emerged as common injury sites. The study highlighted the potential risk of pedestrian injuries, as reflected in higher injury severity, concomitant injuries, and higher mortality. Future studies are needed to optimize preventive measures by incorporating insights into specific injury mechanisms and patterns of UEIs.

Pre- and post-implementation protocol for non-operative management of grade III-V splenic injuries: An observational study.

Background: Grade (III-V) blunt splenic injuries (BSI) in hemodynamically stable patients represent clinical challenges for successful non-operative management (NOM). In 2014, Our institution proposed a treatment protocol requiring splenic angiography and embolization for stable, intermediate, and high-grade BSI. It also included a follow-up CT scan for grade III BSI. We sought to assess the success rate of NOM in treating intermediate and high-grade BSI, following a standardized treatment protocol at a level 1 trauma center. Methods: An observational retrospective study was conducted. Data of patients with BSI from June 2011 to September 2019 were reviewed using the Qatar National Trauma Registry. Patients' demographics, CT scan and angiographic findings, grade of splenic injuries, and outcomes were analyzed. The pre- and post-implementation of treatment protocol periods were compared. Results: During the study period, a total of 552 hemodynamically stable patients with BSI were admitted, of which 240 had BSI with grade III to V. Eighty-one patients (33.8%) were admitted in the pre-protocol implementation period and 159 (66.2%) in the post-protocol implementation period. The NOM rate increased from 50.6% in the pre-protocol group to 65.6% in the post-protocol group (p = 0.02). In addition, failure of the conservative treatment did not significantly differ in the two periods, while the requirement for blood transfusion dropped from 64.2% to 45.9% (p = 0.007). The frequency of CT scan follow-up (55.3% vs. 16.3%, p = 0.001) and splenic arterial embolization (32.7% vs. 2.5%, p = 0.001) in NOM patients increased significantly in the post-protocol group compared to the pre-protocol group. Overall mortality was similar between the two periods. However, hospital and ICU length of stay and ventilatory days were higher in the post-protocol group. Conclusions: NOM is an effective and safe treatment option for grade III-V BSI patients. Using standardized treatment guidelines for intermediate-to high-grade splenic injuries could increase the success rate for NOM and limit unnecessary laparotomy. Moreover, angioembolization is a crucial adjunct to NOM that could improve the success rate.

Empirical Pyridostigmine in a Patient with Difficult Weaning from Mechanical Ventilation after Traumatic Brain Injury.

We present a 30-year-old male who sustained a mild traumatic brain injury and then was intubated due to deterioration of consciousness. A head CT scan revealed mild brain oedema, a fractured nasal bone and mild left thoracic wall haematoma. Despite complete clinical and radiological normalisation within 36 hours, he failed to wean off the ventilator. The patient was found to have subtle bulbar manifestations including dysphonia, dysarthria, and dysphagia, with recurrent left lung collapse. He responded to an empirical pyridostigmine trial despite negative biochemical tests for myasthenia gravis (MG). The patient was weaned successfully from the ventilator, transferred to a long-term care facility, and then discharged home. Classic symptoms and signs of a disease may be absent, but the presence of dysarthria, dysphagia, transient vocal cord palsy, nasal speech, absent gag reflex and respiratory failure in difficult-to-wean patients, with no definitive diagnosis, may warrant an empirical trial of therapy for suspected MG and for the benefit of any doubt. LEARNING POINTS: "Hidden" cranial injuries may account for subtle bulbar symptoms in victims of traumatic brain injury and should be searched for.Myasthenia gravis has been reported in association with trauma, which comes first and is often difficult to ascertain.A trial of pyridostigmine may be reasonable in difficult-to-wean patients when all other causes have been excluded for the benefit of the doubt.

Seizure Prophylaxis in Young Patients Following Traumatic Brain Injury.

Introduction: Phenytoin is one of the commonly used anti.seizure medications in nontraumatic seizures. However, its utility and safety in young patients with traumatic brain injury (TBI) for the prevention of early-onset seizures (EOS) are debatable. We sought to explore the use of phenytoin as a seizure prophylaxis following TBI. We hypothesized that administering phenytoin is not effective in preventing EOS after TBI. Methods: This was a retrospective observational study conducted on adult TBI patients. EOS was defined as a witnessed seizure within a week postinjury. Data were compared as phenytoin versus no-phenytoin use, EOS versus no-EOS, and among TBI severity groups. Results: During 1 year, 639 TBI patients were included with a mean age of 32 years; of them, 183 received phenytoin as seizure prophylaxis, and 453 received no prophylaxis medication. EOS was documented in 13 (2.0%) patients who received phenytoin, and none had EOS among the nonphenytoin group. The phenytoin group was more likely to have a higher Marshall Score (P = 0.001), lower Glasgow Coma Scale (GCS) (P = 0.001), EOS (P = 0.001), and higher mortality (P = 0.001). Phenytoin was administrated for 15.2%, 43.2%, and 64.5% of mild, moderate, and severe TBI patients, respectively. EOS and no-EOS groups were comparable for age, gender, mechanism of injury, GCS, Marshall Score, serum phenytoin levels, liver function levels, hospital stay, and mortality. Multivariable logistic regression analysis showed that low serum albumin (odds ratio [OR] 0.81; 95% confidence interval [CI] 0.676.0.962) and toxic phenytoin level (OR 43; 95% CI 2.420.780.7) were independent predictors of EOS. Conclusions: In this study, the prophylactic use of phenytoin in TBI was ineffective in preventing EOS. Large-scale matched studies and well-defined hospital protocols are needed for the proper utility of phenytoin post-TBI.

Diagnosis and treatment of epiploic appendagitis in a Middle Eastern country: An observational retrospective analysis of 156 cases.

BACKGROUND: Epiploic appendagitis (EPA) is an uncommon emergency surgical condition that causes acute abdominal pain, rendering a list of differential diagnoses. Therefore, careful examination and imaging tools are required. EPA is a self-limiting condition that can be resolved in 1-2 weeks and rarely needs surgical intervention. Its low incidence makes EPA less well-known among the public and some medical professionals, and it is frequently under-diagnosed. We aimed to explore the incidence, clinical presentation, modalities of imaging to diagnose and options for treating EPA. METHODS: An observational retrospective analysis was conducted between 2016 and 2022 at a tertiary hospital in an Arab Middle Eastern country. RESULTS: There were 156 EPA cases diagnosed over six years, with a mean age of 33 years. Males represented 82% of the cohort. The entire cohort was treated non-operatively except for eight patients who had surgical intervention using open or laparoscopic surgery. The diagnosis was made by a computerized tomographic scan (CT). However, plain X-ray, abdominal ultrasound, and magnetic resonance imaging (MRI) were performed initially in a few selected cases to rule out other conditions. No specific blood test indicated EPA; however, a histopathology examination was diagnostic. No mortality was reported in the study cohort. CONCLUSION: This is the most extensive study analyzing EPA patients from the Middle East. EPA is a rare and mostly self-limiting acute abdominal disorder; however, early ultrasound and CT scan can pick it up quickly after a high index of suspicion.

Utility of indocyanine green fluorescent dye in emergency general surgery: a review of the contemporary literature.

For decades, indocyanine green (ICG) has been available for medical and surgical use. The indications for ICG use in surgery have expanded where guided surgery directed by fluorescence and near-infrared fluorescent imaging offers numerous advantages. Recently, surgeons have reported using ICG operative navigation in the emergency setting, with fluorescent cholangiography being the most common procedure. The utility of ICG also involves real-time perfusion assessment, such as ischemic organs and limbs. The rising use of ICG in surgery can be explained by the ICG's rapid technological evolution, accuracy, ease of use, and great potential to guide precision surgical diagnosis and management. The review aims to summarize the current literature on the uses of ICG in emergency general surgery. It provides a comprehensive and practical summary of the use of ICG, including indication, route of administration, and dosages. To simplify the application of ICG, we subdivided its use into anatomical mapping and perfusion assessment. Anatomical mapping includes the biliary tree, ureters, and bowel. Perfusion assessment includes bowel, pancreas, skin and soft tissue, and gonads. This review provides a reference to emergency general surgeons to aid in implementing ICG in the emergency setting for more enhanced and safer patient care.

Can "Stop The Bleed" training courses for laypersons improve hemorrhage control knowledge, skills, and attitudes? A systematic review.

BACKGROUND: In many regions of the world, most trauma deaths occur within 1-2 h of injury due to uncontrolled bleeding. For this reason, training lay first-person responders in trauma care, focusing on hemorrhage control, has been recommended. We hypothesized that STOP THE BLEED (STB) training courses that teach laypersons how to stop traumatic compressible bleeding immediately are needed to potentially prevent deaths due to hemorrhage. This systematic review will analyze the effect of the STB training course on the knowledge, skill, and attitudes of lay first-person responders for hemorrhage control. METHODS: PubMed and Google Scholar databases were used to identify relevant peer-reviewed research articles describing evaluations of STB courses for laypersons from December 1 2013 to October 31 2022. In addition, a hand search of article references was undertaken. Studies were included if they implemented the STB course; trainees were laypersons, and the study had some outcome measures such as knowledge, skill, confidence gained, and willingness to provide or utilization of care provided to and outcomes of trauma patients. RESULTS: The database searches yielded 2,893 unique papers. We retained 33 articles for full-text review, resulting in 24 eligible papers. Gray literature and manual searches yielded 11 additional publications for a total of 35 studies. The most reported finding was a statistically significant increase in hemorrhage control knowledge or tourniquet application skills in 26 studies. Twenty-two studies reported statistically significant improvements in willingness, confidence, comfort, and likelihood to respond to a bleeding patient, and 6 studies reported substantial reductions in the retention of bleeding control knowledge or skills. Only one study reported on the effect on patient outcomes. CONCLUSION: STB courses for laypersons have demonstrated significant improvements in knowledge, skill, confidence, and willingness to intervene to stop traumatic exsanguination. The evaluation of clinically relevant patient outcomes, specifically their effect on preventable deaths from traumatic exsanguination, is needed to strengthen further the evidence behind the recommendations for more widespread teaching of "STB" courses.

Motorcycle-related crashes before and during the COVID-19 pandemic: A comparative retrospective observational study from the Middle East.

BACKGROUND: During the COVID-19 pandemic, there was a boom in the delivery sector, with a significant increase in the demand and number of motorcycle delivery drivers in Qatar, which made them vulnerable to injury. We aimed to evaluate the incidence, pattern, and outcome of patients injured by motorcycle-related crashes (MCC) before and during the pandemic. METHODS: A retrospective observational study included all adult patients admitted with motorcycle-related injuries before the pandemic (March 2018 to February 2020) and during the pandemic (March 2020 to March 2022). Comparative analyses were performed based on (work versus non-work related MCCs) and (pre- versus during the pandemic injuries). RESULTS: 510 patients with MCC were identified, of which 172 (33.7 %) were admitted in the pre-pandemic and 338 (66.3 %) during the pandemic. The mean age of patients was 29.2±7.8 years; 56 % were aged 20-29 years, and 99.4 % were males. Work-related MCCs were more frequent among the younger age group (60.9 % vs. 52.1 %; p=0.001) during the early evening, i.e., 6:00 to 9:00 p.m. (21.9 % vs. 13.9 %; p=0.004). However, non-work related MCC occurred more frequently between midnight and 3:00 am (20.2 % vs. 10.9 %; p=0.004), and such patients were more likely non-compliant for protective devices use (19.3 % vs. 6.1 %; p=0.001) and ride under the influence of alcohol (13.2 % vs. 7.4 %; p=0.03). During the pandemic, the proportion of alcohol consumers (13 % vs. 5.8 %; p=0.01) and work-related MCC (50.9 % vs. 22.7 %; p=0.001) increased significantly compared to the pre-pandemic period. CONCLUSION: The overall burden of MCC increased during the pandemic, and the frequency of MCC involving commercial drivers surged significantly during the pandemic period as opposed to the non-work MCC, which predominated in the pre-pandemic period. Work-related MCCs were more frequent among younger age groups, mainly involving South Asians with frequent accidents in the evening time. However, recreation-related MCCs occurred more frequently at midnight, and victims were non-compliant with the protective gear. Furthermore, there is a need for prospective studies to examine the broader scope of risk factors that are associated with the work-related MCC, especially involving food deliveries, and for focused safety programs for motorcycle delivery drivers and recreational motorcyclists.

Time and Risk Factors of Trauma-Related Mortality: A 5-Year Retrospective Analysis From a National Level I Trauma Center.

Background: We aimed to analyze in-hospital timing and risk factors for mortality in a level 1 trauma center. Methods: This is a retrospective analysis of all trauma-related mortality between 2013 and 2018. Patients were divided and analyzed based on the time of mortality (early (≤48 h) vs late (>48 h)), and within different age groups. Multivariate regression analysis was performed to predict in-hospital mortality. Results: 8624 trauma admissions and 677 trauma-related deaths occurred (47.7% at the scene and 52.3% in-hospital). Among in-hospital mortality, the majority were males, with a mean age of 35.8 ± 17.2 years. Most deaths occurred within 3-7 days (35%), followed by 33% after 1 week, 20% on the first day, and 12% on the second day of admission. Patients with early mortality were more likely to have a lower Glasgow coma scale, a higher shock index, a higher chest and abdominal abbreviated injury score, and frequently required exploratory laparotomy and massive blood transfusion (P < .005). The injury severity scores and proportions of head injuries were higher in the late mortality group than in the early group. The severity of injuries, blood transfusion, in-hospital complications, and length of intensive care unit stay were comparable among the age groups, whereas mortality was higher in the age group of 19 to 44. The higher proportions of early and late in-hospital deaths were evident in the age group of 24 to 29. In multivariate analysis, the shock index (OR 2.26; 95%CI 1.04-4.925; P = .04) was an independent predictor of early death, whereas head injury was a predictor of late death (OR 4.54; 95%CI 1.92-11.11; P = .001). Conclusion: One-third of trauma-related mortalities occur early after injury. The initial shock index appears to be a reliable hemodynamic indicator for predicting early mortality. Therefore, timely hemostatic resuscitation and appropriate interventions for bleeding control may prevent early mortality.

Beta-Adrenergic Receptor Polymorphism and Patho-Genetics of Trauma: A Transformational Frontier of Personalized Medicine in Neurotrauma.

Trauma is a serious public health issue, and remains a major cause of mortality and disability worldwide. The notion that genetic factors contribute to an individual's response to traumatic injury has advanced significantly. Genetic variations in severely injured patients have been linked to mortality, morbidity, and psychological outcomes. We conducted a comprehensive review of beta-adrenergic receptor polymorphisms and their impact on the pathogenetics of traumatic injuries, which could pave the way for a transformational frontier of personalized medicine in neurotrauma. It remains unclear why some individuals are vulnerable to worse outcomes, whereas others are resilient. Although genetic factors may be significant, the intricate interplay between environmental and genetic factors may be responsible for variations in the presentation and outcome after injury. Recent advancements in genetic analysis and molecular physiology have helped to shed light on the causes of such variability. Although exposure to trauma can initiate a cascade of stress-related responses, these responses alone are insufficient to explain etiopathogenesis. Therefore, gaining insights into how trauma and genetic predispositions to adrenergic variations interact at the molecular level to affect an individual's susceptibility and recuperation could provide an essential understanding of the molecular pathogenesis of traumatic injuries. Therefore, it is imperative to identify potential genetic and physiological markers to guide early management and prognosis of trauma. Such knowledge could pave the way for the discovery of novel biomarkers that can identify a transdiagnostic subgroup that is at high risk and requires early intervention. This could lead to the adoption of personalized medical approaches in neurotrauma care.

Implementation of Mandatory Blood Alcohol Screening in Trauma Patients: A Retrospective Study from a Tertiary Trauma Center in a Middle Eastern Country.

BACKGROUND: Alcohol consumption is a significant risk factor for several types of injuries and trauma recidivism and remains an important public health concern worldwide. We aimed to describe the implementation of mandatory alcohol screening and the AUDIT tool among trauma patients admitted to a level 1 trauma center in a country with a partial ban on alcohol consumption. METHODS: This was a retrospective analysis of trauma patients (>12 years old) who required hospital admission and underwent blood alcohol concentration (BAC) screening between 2014 and 2019. This was achieved via an enzymatic method using alcohol dehydrogenase for ethanol detection in the plasma and serum samples. Trauma patient with a BAC < 2.2 mmol/L was referred to as "negative," and BAC > 2.2 mmol/L was referred to as "BAC positive." A comparative analysis was performed between the two BAC groups. Alcohol Screening, Brief Intervention, Referral for Treatment [ASBIRT] program, and AUDIT were applied. RESULTS: A total of 7,326 BAC screening tests were performed in 7,284 patients during the study period. With slight variation over the years, the compliance rate was 77% (70.4%-85.3%), and the test-positivity rate was 10% (8.6%-12.5%). There were 42 repeated admissions, of which seven patients were BAC positive at every admission. Young age and non-Arab patients were more likely to test positive, and the main mechanism of injury (MOI) was road traffic-related trauma (p<0.05). Assault and self-inflicted injuries were significantly higher in BAC-positive patients than in BAC-negative patients (18% vs 4% and 2.7% vs 1.3%, respectively; p=0.001). The injury severity score (ISS) and mortality rate were comparable between the study groups. Patients with a positive BAC were significantly more likely to undergo pan-CT scan in the emergency department, intubation, and exploratory laparotomy than those with a negative BAC. In patients who sustained injuries due to assault, all-terrain vehicles, or motorcycle crashes, there was a significant association between the positivity of BAC tests and the patient' ISS. CONCLUSION: Despite improvements in BAC screening in trauma admissions over the years, almost 20% of cases were missed. Although the mortality rates were comparable, alcohol consumption burdens resources in terms of excess imaging, intubation, open abdominal surgery, and possible disability. Further studies are needed to understand the key obstacles and challenges to achieving optimum compliance for screening in trauma settings.

Academic and healthcare efforts from Cessation to complete resumption of professional football tournaments during COVID-19 pandemic: A narrative review.

The Coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus led to over 626 million infections and 6.5 million deaths worldwide and forced to cancel or postpone several sporting events. Effective control techniques are therefore urgently required to avoid COVID-19 spread at these local and global events. This narrative review addressed the healthcare and research efforts on the intersections between COVID-19 and major professional sports leagues worldwide, with special reference to the FIFA World Cup football 2022. This explained how the broader transformation of COVID-19 from being a potential risk to an urgent pandemic public health emergency, caused the world of Football to halt between February and March 2020. This review could add to the growing literature on the importance of scientific research in understanding the relationship between mass sports events and COVID-19 trajectory, concerning studies conducted globally and particularly for the recommencement of major professional football competitions. The information outlined in the article may help sports organizations understand the risks associated with sports and their settings and improve their preparedness for future events under unprecedented circumstances. There were tremendous global healthcare and research efforts to deal with this unprecedented pandemic. The successful FIFA World Cup football tournament was an indicator of the success of these efforts.

Patterns and Outcomes of Obesity Using Body Mass Index in Patients Hospitalized with Acute Cardiovascular Disorders: A Retrospective Analysis of 7284 Patients in a Middle Eastern Country.

BACKGROUND: We aimed to study the presentation and in-hospital outcomes of obese patients hospitalized for cardiovascular diseases (CVDs) in a Middle Eastern country. METHODS: This retrospective study included patients admitted to the Heart Hospital between 2015 and 2020. Patients were divided according to their body mass index (BMI): Group I (BMI 18.5-24.9), Group II (BMI 25-29.9), and Group III (BMI ≥ 30), by applying one-way ANOVAs and chi-square tests. The obese group (BMI ≥ 30) was graded and compared (Grade I (BMI 30-34.9), Grade II (BMI 35-39.9), and Grade III (BMI ≥ 40)). RESULTS: There were 7284 patients admitted with CVDs (Group I (29%), Group II (37%), and Group III (34%)). The mean age was higher in Group III than Groups I and II (p < 0.001). Male sex was predominant in all groups except for morbid obesity (Grade III), in which females predominated. Diabetes mellitus (DM), hypertension, and dyslipidemia were more common in Group III. Chest pain was more common in Group II, while shortness of breath was more evident in Group III (p < 0.001). Group II had more ST-elevation myocardial infarction (STEMI), followed by Group I (p < 0.001). Atrial fibrillation (AF) was observed more frequently in Group III (p < 0.001). Congestive heart failure (CHF) was common in Group III (19%) (p < 0.001). In the subanalysis, (Grade I (62%), Grade II (22.5%), and Grade III (15.5%)), Grade I had more STEMI, whereas AF and CHF were higher in Grade III (p < 0.001). Percutaneous Coronary Intervention was performed less frequently in Grade III (p < 0.001). In-hospital mortality was higher in Grade III (17.1%), followed by Grades II (11.2%) and I (9.3%) (p < 0.001). CONCLUSIONS: In this study, one third of the hospitalized CVS patients were obese. AF and CHF with preserved EF were the most common cardiovascular presentations in obese patients. In patients with CVDs, obesity was associated with higher rates of comorbidities and in-hospital mortality. However, obesity measured by BMI alone was not an independent predictor of mortality in obese cardiac patients.

Pneumoscrotum with extensive subcutaneous emphysema in traumatic perineal injury: A case report.

Key Clinical Message: We present a rare case of pneumoscrotum with subsequent subcutaneous emphysema in penetrating perineal injury with a tangential wound. It is important to diagnose the underlying disease and treat the cause. An examination under anesthesia is crucial for the diagnosis and management of the set of injuries. Abstract: Pneumoscrotum with subcutaneous emphysema in traumatic perineal injuries is an alarming sign and may indicate life-threatening intraabdominal injuries or necrotizing fasciitis. We reported a case of pneumoscrotum and extensive subcutaneous emphysema of the abdomen and chest 2 days after admission. Pneumoscrotum was not seen on the initial Computerized tomographic scan.

Trauma Quality Improvement Program: A Retrospective Analysis from A Middle Eastern National Trauma Center.

BACKGROUND: The Trauma Quality Improvement Program (American College of Surgery (ACS-TQIP)) uses the existing infrastructure of the Committee on Trauma programs and provides feedback to participating hospitals on risk-adjusted outcomes. This study aimed to analyze and compare the performance of the Level I Hamad Trauma Centre (HTC) with other TQIP participating centers by comparing TQIP aggregate database reports. The primary goal was to pinpoint the variations in adult trauma outcomes and quality measures, identify areas that need improvement, and leverage existing resources to facilitate quality improvement. METHODS: A retrospective analysis was performed for the TQIP data from April 2019-March 2020 to April 2020-March 2021. We used the TQIP methodology, inclusion and exclusion criteria, and outcomes. RESULTS: There were 915 patients from Fall 2020 and 884 patients from Fall 2021 that qualified for the TQIP database. The HTC patients' demographics differed from the TQIP's aggregate data; they were younger, more predominantly male, and had significantly different mechanisms of injury (MOI) with more traffic-related blunt trauma. Penetrating injuries were more severe in the other centers. During the TQIP Fall 2020 report, the HTC was a low outlier (good performer) in one cohort (all patients) and an average performer in the remaining cohorts. However, during Fall 2021, the HTC showed an improvement and was a low outlier in two cohorts (all patients and severe TBI patients). Overall, the HTC remained an average performer during the report cycles. CONCLUSIONS: There was an improvement over time in the risk-adjusted mortality, which reflects the continuous and demanding effort put together by the trauma team. The ACS-TQIP for the external benchmarking of quality improvement could be a contributor to better monitored patient care. Evaluating the TQIP data with emphases on appropriate methodologies, quality measurements, corrective measures, and accurate reporting is warranted.
