CD4+ T cells with latent HIV-1 have reduced proliferative responses to T cell receptor stimulation.

The latent reservoir for HIV-1 in resting CD4+ T cells persists despite antiretroviral therapy as a barrier to cure. The antigen-driven proliferation of infected cells is a major mechanism of reservoir persistence. However, activation through the T cell antigen receptor (TCR) can induce latent proviruses, leading to viral cytopathic effects and immune clearance.

Does lower extremity fracture fixation technique influence neurologic outcomes in patients with traumatic brain injury? The EAST Brain vs. Bone multicenter trial.

Objective: This study aimed to determine whether lower extremity fracture fixation technique and timing (≤24 vs. >24 hours) impact neurologic outcomes in TBI patients.

Methods: A prospective observational study was conducted across 30 trauma centers.

Emergency General Surgery Procedures in Older Adults: Where You Live Matters!

Background: Neighborhood location and its built environment are important social determinants of health that impact health outcomes. Older adults (OAs) represent the fastest growing population in the United States with many requiring emergency general surgery procedures (EGSPs). The aim of this study was to evaluate whether neighborhood location, represented by zip code, influences mortality and disposition in OAs undergoing EGSPs in Maryland.

Acute Care Surgery and Surgical Rescue: Expanding the Definition.

Background: Surgical rescue (SR) is the recovery of patients with surgical complications. Patients transferred (TP) for surgical diagnoses to higher-level care or inpatients (IP) admitted to nonsurgical services may develop intra-abdominal infection (IAI) and require emergency surgery (ES). The aims were to characterize the SR population by the site of ES consultation, open abdomen (OA), and risk of mortality.

Measuring the latent reservoir for HIV-1: Quantification bias in near full-length genome sequencing methods.

Antiretroviral therapy (ART) effectively inhibits HIV-1 replication but is not curative due to the persistence of a latent viral reservoir in resting CD4+ T cells. This reservoir is a major barrier to cure. Sequencing studies have revealed that the population of proviruses persisting in ART-treated individuals is dominated by defective proviruses that cannot give rise to viral rebound due to fatal defects including large deletions and APOBEC3-mediated hypermutation.

Observed relationships between driver and passenger restraint use in the front and rear seats.

Objective: Seat belt usage has increased substantially since the 1960s, yet driver use continues to affect passenger usage. Recent observational restraint use findings for Maryland will examine the relationship between driver and passenger usage, including adults and children in the rear seat.

Methods: Analyses were based on observational front and rear seat studies administered in parallel from 2016 to 2019.

Cost Differences Between Teaching and Nonteaching Hospitals for Older Adults Requiring Emergency General Surgery Procedures in the State of Maryland.

Background: Older adults (OAs; ≥ 65 years) comprise a growing population in the United States and are anticipated to require an increasing number of emergency general surgery procedures (EGSPs). The aims of this study were to identify the frequency of EGSPs and compare cost of care in OAs managed at teaching hospitals (THs) vs nonteaching hospitals (NTHs).

Methods: A retrospective review of data from the Maryland Health Services Cost Review Commission database from 2009 to 2018 for OAs undergoing EGSPs was undertaken.

Validation of the American Association for the Surgery of Trauma Emergency General Surgery Grading System for Colorectal Resection: An EAST Multicenter Study.

Methods: Patients enrolled in the "Eastern Association for the Surgery of Trauma Multicenter Colorectal Resection in EGS-to anastomose or not to anastomose" study undergoing urgent/emergent surgery for obstruction, ischemia, or diverticulitis were included.

Factors associated with stroke formation in blunt cerebrovascular injury: An EAST multicenter study.

Background: Stroke risk factors after blunt cerebrovascular injury (BCVI) are ill-defined. We hypothesized that factors associated with stroke for BCVI would include medical therapy (i.e.

Emergency General Surgery Procedures and Cost of Care for Older Adults in the State of Maryland.

Background: Older adults (OAs) 65 years of age, representing the fastest growing segment in the United States, are anticipated to require a greater percentage of emergency general surgery procedures (EGSPs) with an associated increase in health care costs. The aims of this study were to identify the frequency of EGSP and charges incurred by OA compared to their younger counterparts in the state of Maryland.

Methods: A retrospective review of the Maryland Health Services Cost Review Commission from 2009 to 2018 was undertaken.

Pre-operative fluid resuscitation in the emergency general surgery septic patient: does it really matter?

Objective: Emergency general surgery (EGS) patients presenting with sepsis remain a challenge. The Surviving Sepsis Campaign recommends a 30 mL/kg fluid bolus in these patients, but recent studies suggest an association between large volume crystalloid resuscitation and increased mortality. The optimal amount of pre-operative fluid resuscitation prior to source control in patients with intra-abdominal sepsis is unknown.

Surgical Intensivist-Led Training in Critical Care Ultrasound Improves Performance.

Background: Critical care ultrasound (CCUS) is essential in modern practice, with CCUS including cardiac and noncardiac ultrasound. The most effective CCUS training is unknown, with a diverse skill set and knowledge needed for competence. The objective of this project was to evaluate the effect of a surgical intensivist-led training program on CCUS competence in critical care fellows.

Colorectal resection in emergency general surgery: An EAST multicenter trial.

Objective: Evidence comparing stoma creation (STM) versus anastomosis after urgent or emergent colorectal resection is limited. This study examined outcomes after colorectal resection in emergency general surgery patients.

Methods: This was an Eastern Association for the Surgery of Trauma-sponsored prospective observational multicenter study of patients undergoing urgent/emergent colorectal resection.

The impact of a new casino on the motor vehicle crash patterns in suburban Maryland.

Background: Many states have legalized casino gambling, and casinos create increased vehicle traffic, but the strength of the association between casino construction and vehicle crashes is unknown.

Methods: Retrospective analyses of motor vehicle crashes (MVCs) occurring within Anne Arundel County, Maryland (2010-2014) were conducted. The ratio of crashes within one mile of the casino's location after it was opened were compared to the ratio occurring in the same area before it was opened to determine how the incidence of MVCs near the casino changed with time.

Methylprednisolone may be associated with improved lung compliance in acute respiratory distress syndrome patients on veno-venous extracorporeal membrane oxygenation.

Introduction: Methylprednisolone has been used for acute respiratory distress syndrome with variable results. Veno-venous extracorporeal membrane oxygenation use in acute respiratory distress syndrome has increased. Occasionally, both are used.

Is Opioid Prescribing Driving Trauma Recidivism or Is Trauma Driving Opioid Use?

In the past 30 years, opioid prescription rates have quadrupled and hospital admissions for overdose are rising. Previous studies have focused on alcohol use and trauma recidivism, however rarely evaluating recidivism and opioid use. We hypothesized there is an association between opioid use and trauma recidivism.

Infection after penetrating brain injury-An Eastern Association for the Surgery of Trauma multicenter study oral presentation at the 32nd annual meeting of the Eastern Association for the Surgery of Trauma, January 15-19, 2019, in Austin, Texas.

Background: Fatality rates following penetrating traumatic brain injury (pTBI) are extremely high and survivors are often left with significant disability. Infection following pTBI is associated with worse morbidity. The modern rates of central nervous system infections (INF) in civilian survivors are unknown.

Penetrating Renal Trauma: Nonoperative Management Is Safe in Selected Patients.

Present literature seems to support the nonoperative management of penetrating renal trauma although data remain limited. We conducted a nine-year retrospective review of nonoperative operative management and mechanism of injury [stab wound (SW) gunshot wound (GSW)] among patients admitted with penetrating renal trauma. Of 203 patients, the median age was 24 years, with the majority being male and having GSW injuries.

A quantitative approach for measuring the reservoir of latent HIV-1 proviruses.

A stable latent reservoir for HIV-1 in resting CD4 T cells is the principal barrier to a cure. Curative strategies that target the reservoir are being tested and require accurate, scalable reservoir assays. The reservoir was defined with quantitative viral outgrowth assays for cells that release infectious virus after one round of T cell activation.

Comparison of individual and composite radiographic markers of frailty in trauma.

Background: Clinical frailty scores usually involve questionnaires or physical testing. Many trauma patients are not able to participate in these. Radiographic measurement of frailty may be a viable alternative.

Red Blood Cell Transfusions and Anemia on Admission Are Associated with Poor Outcomes in Necrotizing Soft Tissue Infections.

Background: Necrotizing soft tissue infections (NSTIs) are highly morbid infections often requiring critical care and transfusion support. We explored a large 2-year experience from a regional trauma center with a dedicated soft tissue service (STS) in an attempt to identify factors in current care with potential for improving outcomes for these critically ill patients.

Methods: New adult (>17 years) STS admissions, 2008-2009, were identified from the Trauma Registry.

Veno-Venous Extracorporeal Membrane Oxygenation for Respiratory Failure: How Long Is Too Long?

The use of veno-venous extracorporeal membrane oxygenation (VV ECMO) in adults with respiratory failure has steadily increased during the past decade. Recent literature has demonstrated variable outcomes with the use of extended ECMO. The purpose of this study is to evaluate survival to hospital discharge in patients with extended ECMO runs compared with patients with short ECMO runs at a tertiary care ECMO referral center.
