Demographic and Regional Factors Associated With Reporting Homicides of Transgender People in the United States.

INTRODUCTION: The American Medical Association recently declared homicides of transgender individuals an epidemic. However, transgender homicide victims are often classified as nontransgender. Our objective was to describe existing data and coding of trans (i.e., transgender) victims and to examine the risk factors for homicides of trans people relative to nontrans people across the United States. METHODS: A retrospective review of the Centers for Disease Control and Prevention's National Violent Death Reporting System for the years 2003-2018 identified victims defined as transgender either through the "transgender" variable or narrative reports. Fisher's exact tests and logistic regression models were run to compare the demographics of trans victims to those not identified as trans. RESULTS: Of the 147 transgender victims identified, 14.4% were incorrectly coded as nontrans despite clear indication of trans status in the narrative description, and 6% were coded as hate crimes. Relative to nontrans victims, trans victims were more frequently Black (54.4% versus 40.7%, P = 0.001), had a mental health condition (26.5% versus 11.3%, P < 0.001), or reported being a sex worker (9.5% versus 0.2%, P < 0.001). There were disproportionately few homicides of transgender people in the South (13.6% of trans victims versus 29.1% of nontrans victims, P < 0.001). Conversely, the West and Midwest accounted for a higher-than-expected proportion of trans victims relative to nontrans victims (23.1% of trans victims versus 16.2% of nontrans victims, P = 0.03; 24.5% of trans victims versus 16.8% of nontrans victims, P = 0.02, respectively). CONCLUSIONS: Though the murder of transgender individuals is a known public health crisis, inconsistencies still exist in the assessment and reporting of transgender status. Further, these individuals were more likely to have multiple distinct vulnerabilities. These findings provide important information for injury and violence prevention researchers to improve reporting of transgender status in the medical record and local trauma registries.

Impact and treatment success of new-onset atrial fibrillation with rapid ventricular rate development in the surgical intensive care unit.

BACKGROUND: Atrial fibrillation (AF) with rapid ventricular rate (RVR; heart rate >100) in noncardiac postoperative surgical patients is associated with poor outcomes. The objective of this study was to evaluate the practice patterns of AF management in a surgical intensive care unit to determine practices associated with rate and rhythm control and additional outcomes. MATERIALS AND METHODS: Adult patients (≥18 y) admitted to the surgical intensive care unit (SICU) from June 2014 to June 2015 were retrospectively screened for the development of new-onset AF with RVR. Demographics, hospital course, evaluation and treatment of AF with RVR, and outcome were evaluated and analyzed. RESULTS: Thousand seventy patients were admitted to the SICU during the study period; 33 met inclusion criteria (3.1%). Twenty-six patients (79%) had rate and rhythm control within 48 h of AF with RVR onset. ß-Blockers were the most commonly used initial medication (67%) but were successful at rate and rhythm control in only 27% of patients (6/22). Amiodarone had the highest rate of success if used initially (5/6, 83%) and secondarily (11/13, 85%). Failure to control rate and rhythm was associated with a greater likelihood of comorbidities (100% versus 57%; P = 0.06). CONCLUSIONS: New-onset AF with RVR in the noncardiac postoperative patient is associated with a high mortality (21%). Amiodarone is the most effective treatment for rate and rhythm control. Failure to establish rate and rhythm control was associated with cardiac comorbidities. These results will help to form future algorithms for the treatment of AF with RVR in the SICU.

Trauma surgical skill sustainment at the University of Chicago AMEDD Military-Civilian Trauma Team Training Site: an observation report.

Background: The Army Medical Department (AMEDD) Military-Civilian Trauma Team Training (AMCT3) Program was developed to enhance the trauma competency and capability of the medical force by embedding providers at busy civilian trauma centers. Few reports have been published on the outcomes of this program since its implementation. Methods: The medical and billing records for the two AMCT3 embedded trauma surgeons at the single medical center were retrospectively reviewed for care provided during August 2021 through July 2022. Abstracted data included tasks met under the Army's Individual Critical Task List (ICTL) for general surgeons. The Knowledge, Skills, and Abilities (KSA) score was estimated based on previously reported point values for procedures. To assess for successful integration of the embedded surgeons, data were also abstracted for two newly hired civilian trauma surgeons. Results: The annual clinical activity for the first AMCT3 surgeon included 444 trauma evaluations and 185 operative cases. The operative cases included 80 laparotomies, 15 thoracotomies, and 15 vascular exposures. The operative volume resulted in a KSA score of 21 998 points. The annual clinical activity for the second AMCT3 surgeon included 424 trauma evaluations and 194 operative cases. The operative cases included 92 laparotomies, 8 thoracotomies, and 25 vascular exposures. The operative volume resulted in a KSA score of 22 799 points. The first civilian surgeon's annual clinical activity included 453 trauma evaluations and 151 operative cases, resulting in a KSA score of 16 738 points. The second civilian surgeon's annual clinical activity included 206 trauma evaluations and 96 operative cases, resulting in a KSA score of 11 156 points. Conclusion: The AMCT3 partnership at this single center greatly exceeds the minimum deployment readiness metrics established in the ICTLs and KSAs for deploying general surgeons. The AMEDD experience provided a deployment-relevant case mix with an emphasis on complex vascular injury repairs.

State-Level Analysis of Intimate Partner Violence, Abortion Access, and Peripartum Homicide: Call for Screening and Violence Interventions for Pregnant Patients.

BACKGROUND: Despite representing 4% of the global population, the US has the fifth highest number of intentional homicides in the world. Peripartum people represent a unique and vulnerable subset of homicide victims. This study aimed to understand the risk factors for peripartum homicide. STUDY DESIGN: We used data from the 2018 to 2020 National Violent Death Reporting System to compare homicide rates of peripartum and nonperipartum people capable of becoming pregnant (12 to 50 years of age). Peripartum was defined as currently pregnant or within 1-year postpartum. We additionally compared state-level peripartum homicide rates between states categorized as restrictive, neutral, or protective of abortion. Pearson's chi-square and Wilcoxon rank-sum tests were used. RESULTS: There were 496 peripartum compared with 8,644 nonperipartum homicide victims. The peripartum group was younger (27.4 ± 71 vs 33.0 ± 9.6, p < 0.001). Intimate partner violence causing the homicide was more common in the peripartum group (39.9% vs 26.4%, p < 0.001). Firearms were used in 63.4% of homicides among the peripartum group compared with 49.5% in the comparison (p < 0.001). A significant difference was observed in peripartum homicide between states based on policies regarding abortion access (protective 0.37, neutral 0.45, restrictive 0.64; p < 0.01); the same trend was not seen with male homicides. CONCLUSIONS: Compared with nonperipartum peers, peripartum people are at increased risk for homicide due to intimate partner violence, specifically due to firearm violence. Increasing rates of peripartum homicide occur in states with policies that are restrictive to abortion access. There is a dire need for universal screening and interventions for peripartum patients. Research and policies to reduce violence against pregnant people must also consider the important role that abortion access plays in protecting safety.

Life Over Limb: Why Not Both? Revisiting Tourniquet Practices Based on Lessons Learned From the War in Ukraine.

The use of tourniquets for life-threatening limb hemorrhage is standard of care in military and civilian medicine. The United States (U.S.) Department of Defense (DoD) Committee on Tactical Combat Casualty Care (CoTCCC) guidelines, as part of the Joint Trauma System, support the application of tourniquets within a structured system reliant on highly trained medics and expeditious evacuation. Current practices by entities such as the DoD and North Atlantic Treaty Organization (NATO) are supported by evidence collected in counter-insurgency operations and other conflicts in which transport times to care rarely went beyond one hour, and casualty rates and tactical situations rarely exceeded capabilities. Tourniquets cause complications when misused or utilized for prolonged durations, and in near-peer or peer-peer conflicts, contested airspace and the impact of high-attrition warfare may increase time to definitive care and limit training resources. We present a series of cases from the war in Ukraine that suggest tourniquet practices are contributing to complications such as limb amputation, overall morbidity and mortality, and increased burden on the medical system. We discuss factors that contribute to this phenomenon and propose interventions for use in current and future similar contexts, with the ultimate goal of reducing morbidity and mortality.

Yellow fever vaccine-associated viscerotropic disease.

Yellow fever is a mosquito-transmitted hemorrhagic viral disease that is endemic to tropical regions in South America and Africa. It remains a significant health concern for deploying military personnel, accordingly vaccination is frequently performed on troops. Although the vaccine is generally administered with only minor complications, rare severe complications are also reported. Herein, we report a mild case of yellow fever vaccine-associated viscerotropic disease 4 days after administration of the vaccine. The various complications of the vaccine and their pathogenesis are also reviewed.

Selective nonoperative management of anterior abdominal stab wounds: 1992-2008.

BACKGROUND: The use of selective nonoperative management for anterior abdominal stab wounds has evolved into a readily accepted practice. Multiple reports have shown this strategy to be both safe and effective. However, there is a paucity of long-term studies. METHODS: A retrospective review was performed of all trauma patients presenting for anterior abdominal stab wounds at a Level I trauma center during a 17-year time period. Primary outcomes were the percentage of patients undergoing an exploratory laparotomy and the negative laparotomy rate. RESULTS: A total of 7,033 patients sustained a stab wound with 1,961 involving the anterior abdomen. The percentage of patients undergoing exploratory laparotomy decreased during the study period from 64.8% to 37.6% (overall 45.8%). The negative laparotomy rate decreased from 21.3% to 8.6% (overall 18.7%). The negative laparotomy rate of patients who underwent exploratory laparotomy immediately did not change over time (13.8%), whereas the negative laparotomy rate of those patients who underwent exploratory laparotomy in a delayed fashion decreased from 25.0% to 6.25%. The overall mortality was 1.9%, with 6.2% mortality for patients undergoing an immediate laparotomy, 0.7% for patients undergoing a delayed laparotomy, and 0.0% for patients managed nonoperatively (p<0.04). The mean length of hospital stay was 6.6 days±0.5 days, with a mean of 9.4 days±0.9 days in patients undergoing an immediate laparotomy, 8.1 days±0.5 days in patients undergo a delayed laparotomy, and 3.8 days±0.2 days in patients managed nonoperatively (p<0.001). CONCLUSIONS: Selective nonoperative management for stab wounds to the anterior abdomen is associated with a decreased operative rate and decreased negative laparotomy rate over time. Selective nonoperative management is both safe and effective for anterior abdominal stab wounds.

Pancreaticoduodenectomy in the setting of intestinal malrotation.

Malrotation is an intestinal gestational disorder which not only affects the positioning of the midgut, but also its vascular supply. While this is generally thought of as a pediatric surgical condition, it can have significant implications for adult surgeries as well. Herein we present a patient with asymptomatic nonrotation of the midgut with a concomitant pancreatic adenocarcinoma. The authors review the modifications necessary to perform a pancreaticoduodenectomy in a nonrotated patient. The review includes a caution and emphasis on an understanding of the vascular anatomic variants.

Red blood cell distribution width and outcome in trauma patients.

Context: Red blood cell distribution width (RDW) has been used to predict mortality during infection and inflammatory diseases. It also been purported to be predictive of mortality following traumatic injury. Objective: To identify the role of RDW in predicting mortality in trauma patients. We also sought to identify the role of RDW in predicting the development of sepsis in trauma patients. Methods: A retrospective observational study was performed of the medical records for all adult trauma patients admitted to Loyola University Medical Center from 2007 to 2014. Patients admitted for fewer than four days were excluded. Admission, peak, and change from admission to peak (Δ) RDW were recorded to determine the relationship with in-hospital mortality. Patient age, development of sepsis during the hospitalization, admission to the intensive care unit (ICU), and discharge disposition were also examined. Results: A total of 9,845 patients were admitted to the trauma service between 2007 and 2014, and a total of 2,512 (25.5%) patients fit the inclusion criteria and had both admission and peak values available. One-hundred twenty (4.6%) died while in the hospital. RDW values for all patients were (mean [standard deviation, SD]): admission 14.09 (1.88), peak 15.09 (2.34), and Δ RDW 1.00 (1.44). Admission, peak, and Δ RDW were not significant predictors of mortality (all p>0.50; hazard ratio [HR], 1.01-1.03). However, trauma patients who eventually developed sepsis had significantly higher RDW values (admission RDW: 14.27 (2.02) sepsis vs. 13.98 (1.73) no sepsis, p<0.001; peak RDW: 15.95 (2.55) vs. 14.51 (1.97), p<0.001; Δ RDW: 1.68 (1.77) vs. 0.53 (0.91), p<0.001). Conclusion: Admission, peak, and Δ RDW were not associated with in-hospital mortality in adult trauma patients with a length of stay (LOS) ≥four days. However, the development of sepsis in trauma patients is closely linked to increased RDW values and in-hospital mortality.

Development of atrial fibrillation following trauma increases short term risk of cardiovascular events.

CONTEXT: New onset atrial fibrillation (AF) is associated with poor outcomes in several different patient populations. OBJECTIVES: To assess the effect of developing AF on cardiovascular events such as myocardial infarction (MI) and cerebrovascular accident (CVA) during the acute index hospitalization for trauma patients. METHODS: The Healthcare Cost and Utilization Project State Inpatient Databases for California and Florida were used to identify adult trauma patients (18 years of age or older) who were admitted between 2007 and 2010. After excluding patients with a history of AF and prior history of cardiovascular events, patients were evaluated for MI, CVA, and death during the index hospitalization. A secondary analysis was performed using matched propensity scoring based on age, race, and preexisting comorbidities. RESULTS: During the study period, 1,224,828 trauma patients were admitted. A total of 195,715 patients were excluded for a prior history of AF, MI, or CVA. Of the remaining patients, 15,424 (1.5%) met inclusion criteria and had new onset AF after trauma. There was an associated increase in incidence of MI (2.9 vs. 0.7%; p<0.001), CVA (2.6 vs. 0.4%; p<0.001), and inpatient mortality (8.5 vs. 2.1%; p<0.001) during the index hospitalization in patients who developed new onset AF compared with those who did not. Cox proportional hazards regression demonstrated an increased risk of MI (odds ratio [OR], 2.35 [2.13-2.60]), CVA (OR, 3.90 [3.49-4.35]), and inpatient mortality (OR, 2.83 [2.66-3.00]) for patients with new onset AF after controlling for all other potential risk factors. CONCLUSIONS: New onset AF in trauma patients was associated with increased incidence of myocardial infarction (MI), cerebral vascular accident (CVA), and mortality during index hospitalization in this study.

Laboratory models available to study alcohol-induced organ damage and immune variations: choosing the appropriate model.

The morbidity and mortality resulting from alcohol-related diseases globally impose a substantive cost to society. To minimize the financial burden on society and improve the quality of life for individuals suffering from the ill effects of alcohol abuse, substantial research in the alcohol field is focused on understanding the mechanisms by which alcohol-related diseases develop and progress. Since ethical concerns and inherent difficulties limit the amount of alcohol abuse research that can be performed in humans, most studies are performed in laboratory animals. This article summarizes the various laboratory models of alcohol abuse that are currently available and are used to study the mechanisms by which alcohol abuse induces organ damage and immune defects. The strengths and weaknesses of each of the models are discussed. Integrated into the review are the presentations that were made in the symposium "Methods of Ethanol Application in Alcohol Model-How Long is Long Enough" at the joint 2008 Research Society on Alcoholism (RSA) and International Society for Biomedical Research on Alcoholism (ISBRA) meeting, Washington, DC, emphasizing the importance not only of selecting the most appropriate laboratory alcohol model to address the specific goals of a project but also of ensuring that the findings can be extrapolated to alcohol-induced diseases in humans.

Infiltrating mammary carcinoma with osteoclast-like giant cells.

Mammary carcinoma with osteoclast-like giant cells is an uncommon variant. The following case examines a 36-year-old woman incidentally found to have a left breast mass on routine physical exam. Initial ultrasound-guided core biopsies revealed infiltrating mammary carcinoma with focal mucinous features, for which a left breast lumpectomy and sentinel lymph node biopsy were performed. The sentinel lymph nodes were positive for metastatic mammary carcinoma with osteoclast-like giant cells on permanent section corresponding to the lumpectomy breast specimen, thus a left completion axillary node dissection was subsequently performed.

Intussusception and colonic ischemia in portal hypertension: a case report.

Intestinal intussusception is a relatively uncommon occurrence in adults in comparison to pediatric patients. While the management of intussusception in children is frequently decompression of the involved segment, adults often require surgical resection secondary to frequent association with neoplastic lead points. A less common reason for surgical removal of an intussuscepted segment in adults is the development of ischemic colitis. The authors present an unusual case of adult intussusception with associated ischemic colitis in a patient with portal hypertension awaiting liver transplantation. Portal hypertension is associated with the development of a microvascular colopathy This condition may serve as the lead point for intestinal intussusception. Furthermore, the vascular changes of portal hypertension leave the bowel unable to respond appropriately to the threat of ischemia. The colopathy of portal hypertension may have predisposed our patient to the development of colonic intussusception by submucosal vascular engorgement; it may have also rendered the intussuscepted segment more susceptible to the development of ischemia.

Scholarly Output by Army General Surgery Residents.

INTRODUCTION: To characterize and compare the scholarly activity of applicants to Army First Year Graduate Medical Education (FYGME) general surgery positions over the course of a residency. METHODS: All applicants for the 2011-2012 Army FYGME positions in general surgery were included. Applications were used to obtain demographics and peer-reviewed publications. Publications were verified using PubMed and Google Scholar. Applicants were tracked for acceptance to a FYGME position, graduation from a general surgery program, and future publications. Comparisons were made between selectees and non-selectees. RESULTS: There were 46 applicants for 22 positions. Seven of the selectees (32%) had prior publications versus three non-selectees (12%; p < 0.109). Eighteen of the selectees went on to complete a general surgery residency by 2017. Of those who completed a general surgery residency, 16 (89%) have at least one publication with the mean number of publications of 4.0 versus 10 (43%), and of those not selected had at least one publication and the mean number of publications was 0.7 (p < 0.05). CONCLUSIONS: The majority of applications for general surgery residencies have no prior research publications. However, after 6 years, graduates of a general surgery residency have significantly published out those not selected for training.

Does the Halo Effect for Level 1 Trauma Centers Apply to High-Acuity Nonsurgical Admissions?

CONTEXT: The halo effect describes the improved surgical outcomes at trauma centers for nontrauma conditions. OBJECTIVE: To determine whether level 1 trauma centers have improved inpatient mortality for common but high-acuity nonsurgical diagnoses (eg, acute myocardial infarction [AMI], congestive heart failure [CHF], and pneumonia [PNA]) compared with non--level 1 trauma centers. METHODS: The authors conducted a population-based, retrospective cohort study analyzing data from the Healthcare Cost and Utilization Project State Inpatient Database and the American Hospital Association Annual Survey Database. Patients who were admitted with AMI, CHF, and PNA between 2006-2011 in Florida and California were included. Level 1 trauma centers were matched to non-level 1 trauma centers using propensity scoring. The primary outcome was risk-adjusted inpatient mortality for each diagnosis (AMI, CHF, or PNA). RESULTS: Of the 190,474 patients who were hospitalized for AMI, CHF, or PNA, 94,037 patients (49%) underwent treatment at level 1 trauma centers. The inpatient mortality rates at level 1 trauma centers vs non-level 1 trauma centers for patients with AMI was 8.10% vs 8.40%, respectively (P=.73); for patients with CHF, 2.26% vs 2.71% (P=.90); and for patients with PNA, 2.30% vs 2.70% (P=.25). CONCLUSION: Level 1 trauma center designation was not associated with improved mortality for high-acuity, nonsurgical medical conditions in this study.

Recurrent epiphrenic diverticulum after transabdominal diverticulectomy: report of a case and review of the literature.

Epiphrenic esophageal diverticula are uncommon esophageal disorders; reported recurrence after surgical treatment is rare. We describe a case of recurrence in a patient previously treated with a transhiatal diverticulectomy myotomy and fundoplication. Anatomic factors that may have contributed to this recurrence are discussed.

Development of a Field-Expedient Vascular Trauma Simulator.

The past few years have noted significant declines in combat casualty exposure over the course of a deployment. As a result, overall confidence and comfort in performing potentially life-saving therapies may wane during a deployment. Development of training simulators provides a method for bridging this gap. Herein, a field-expedient vascular trauma trainer for noncompressible torso hemorrhage is described. A low-fidelity simulator was created using a Penrose drain, intravenous tubing, suture, and a cardboard box. A higher-fidelity simulator was created using an aortobifemoral bypass graft, double-lumen endotracheal tube, suture, and an upper torso mannequin. The two trainers were successfully used to train for peripheral shunt placement and definitive vascular repair. The trainer makes use of supplies readily found at most Role 2 and 3 facilities and that are obtainable for Role 1 facilities providing damage control surgery. It provides a just-in-time way to develop and sustain confidence in the damage control principles applicable to vascular injuries.

Proficiency in Improvised Tourniquets for Extremities: A Review.

Tourniquets have become ubiquitous tools for controlling hemorrhage in the modern prehospital environment, and while commercial products are preferable, improvised tourniquets play an important role when commercial options are not available. A properly constructed improvised tourniquet can be highly effective provided the user adheres to certain principles. This review article identifies key skills in the construction and application of improvised tourniquets on an extremity. An improvised tourniquet design for an extremity should include three components: a strap, a rod, and a securing mechanism. The strap can be made from a variety of materials, but cravat- like fabric has been shown to work well. Optimal strap dimensions should be at least 2cm in width and a continuous segment long enough to extend around the extremity while still offering ends to accommodate and secure the rod. The rod should be constructed from a material that is hard, strong, and capable of withstanding the torque placed on it without bending or breaking. After torque is applied, the rod must be secured into position to maintain the constricting force and survive patient transport. Finally, the need for an improvised tourniquet is a contingency that all first responders should anticipate. Hands-on training should be conducted routinely in conjunction with other first responder tasks.

Sulfur Mustard Exposure: Review of Acute, Subacute, and Long-Term Effects and Their Management.

Sulfur mustard has been used in conflicts for more than a century. Despite international recognized bans on the use of chemical weapons, there continue to be reports of their use. The authors provide a contemporary overview of sulfur mustard injury and its management in the acute, subacute, and chronic periods.
