Optimizing Perioperative Fluid Management in Complex Abdominal Wall Reconstruction to Prevent Postoperative Acute Kidney Injury.

Background: Acute kidney injury (AKI) is a serious postoperative complication of abdominal wall reconstruction that can significantly impact outcomes of these patients. This study examines AKI following abdominal wall hernia repair to determine incidence and risk factors and outline potential mitigation strategies.

Methods: Using a single institution IRB-approved prospective database, patients undergoing complex abdominal wall reconstruction from 2013 to 2021 were identified.

Traumatic Brain Injury Causes Chronic Cortical Inflammation and Neuronal Dysfunction Mediated by Microglia.

Traumatic brain injury (TBI) can lead to significant neuropsychiatric problems and neurodegenerative pathologies, which develop and persist years after injury. Neuroinflammatory processes evolve over this same period. Therefore, we aimed to determine the contribution of microglia to neuropathology at acute [1 d postinjury (dpi)], subacute (7 dpi), and chronic (30 dpi) time points.

Comparison between midline and lateral fluid percussion injury in mice reveals prolonged but divergent cortical neuroinflammation.

Animal models are critical for determining the mechanisms mediating traumatic brain injury-induced (TBI) neuropathology. Fluid percussion injury (FPI) is a widely used model of brain injury typically applied either midline or parasagittally (lateral). Midline FPI induces a diffuse TBI, while lateral FPI induces both focal cortical injury (ipsilateral hemisphere) and diffuse injury (contralateral hemisphere).

Modeling Human Cancer-induced Cachexia.

Cachexia is a wasting syndrome characterized by pronounced skeletal muscle loss. In cancer, cachexia is associated with increased morbidity and mortality and decreased treatment tolerance. Although advances have been made in understanding the mechanisms of cachexia, translating these advances to the clinic has been challenging.

Evaluation of Rectal Vancomycin Irrigation for Treatment of Infection in Patients Post-Colectomy for Toxic Colitis.

infection (CDI) accounts for as many as 25% of episodes of antibiotic-associated diarrhea and is the most common cause of healthcare-associated diarrhea. Rectal vancomycin irrigation is a therapy option; however, evidence is limited for its value post-colectomy. The objective of this study was to describe outcomes of patients who underwent total colectomy for fulminant colitis and received rectal vancomycin post-operatively.

μImpact of a nursing-driven sedation protocol with criteria for infusion initiation in the surgical intensive care unit.

Purpose: Analgesia and sedation protocols (ASPs) reduce duration of mechanical ventilation (MV) in the medical intensive care unit (ICU), but data in the surgical ICU (SICU) are limited. The objective of this study was to determine the impact of a nursing-driven ASP with criteria for infusion initiation in the SICU.

Materials And Methods: A single-center, retrospective study compared ventilator-free days at day 28 from start of MV (VFD28) before and after ASP implementation.

Traumatic brain injury-induced neuronal damage in the somatosensory cortex causes formation of rod-shaped microglia that promote astrogliosis and persistent neuroinflammation.

Microglia undergo dynamic structural and transcriptional changes during the immune response to traumatic brain injury (TBI). For example, TBI causes microglia to form rod-shaped trains in the cerebral cortex, but their contribution to inflammation and pathophysiology is unclear. The purpose of this study was to determine the origin and alignment of rod microglia and to determine the role of microglia in propagating persistent cortical inflammation.

Improving the mortality index by capturing patient acuity through interprofessional real-time documentation improvement in a single hospital system.

Background: The observed to expected mortality ratio is a standardized way for reporting inpatient mortality and is used as a measure for hospital quality rankings and Centers for Medicare & Medicaid Services value-based payments. The goal of this study is to describe a single institution's mortality index improvement initiative through improved documentation of patient severity.

Methods: Data were prospectively collected October 2016 through May 2017 on patients discharged from the acute care surgery, open heart surgery, neurosurgery, and University Hospital East.

Daily review of AHRQ patient safety indicators has important impact on value-based purchasing, reimbursement, and performance scores.

Background: The Patient Safety Indicators (PSIs) Composite (PSI 90) of the Agency for Healthcare Research and Quality has been found to have low positive predictive values. Because scores can affect hospital reimbursement and ranking, our institution designed a review process to ensure accurate data and incur minimal penalties under the Hospital Value-Based Purchasing Program.

Methods: A multidisciplinary team was assembled to review PSI 90 within a performance period.

Mortality and readmission of outcomes after discharge from the surgical intensive care unit to long-term, acute-care hospitals.

Background: Patients with prolonged hospitalizations in the surgical intensive care unit often have ongoing medical needs that require further care at long-term, acute-care hospitals upon discharge. Setting expectations for patients and families after protracted operative intensive care unit hospitalization is challenging, and there are limited data to guide these conversations. The purpose of this study was to determine patient survival and readmission rates after discharge from the surgical intensive care unit directly to a long-term, acute-care hospital.

Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicator for Postoperative Respiratory Failure (PSI 11) does not identify accurately patients who received unsafe care.

Background: The Agency for Healthcare Research and Quality Patient Safety Indicator 11 is used to identify postoperative respiratory failure events and detect areas for quality improvement. This study examines the accuracy of Patient Safety Indicator 11 in identifying clinically valid patient safety events.

Methods: All cases flagged for Patient Safety Indicator 11 from July 2013 to July 2015 by Agency for Healthcare Research and Quality QI Version 4.

Predictors of discharge to an inpatient rehabilitation facility after a single-level posterior spinal fusion procedure.

Purpose: To determine perioperative characteristics of patients undergoing single-level spinal fusion surgery that could help predict discharge to an inpatient rehabilitation facility (IRF).

Methods: Demographic, peri- and postoperative characteristics were reviewed for 107 patients who underwent single-level spinal fusion surgery at a high-volume level I trauma center between January 2011 and December 2013. The relationships between discharge to IRF and gender, age, body mass index (BMI), Charlson Comorbidity Index (CCI), insurance provider, length of stay (LOS), intra- and postoperative outcomes and readmission rates in patients undergoing single-level spinal fusion surgery were analyzed using unpaired and paired t testing.

Cognitive deficits develop 1month after diffuse brain injury and are exaggerated by microglia-associated reactivity to peripheral immune challenge.

Unlabelled: Traumatic brain injury (TBI) elicits immediate neuroinflammatory events that contribute to acute cognitive, motor, and affective disturbance. Despite resolution of these acute complications, significant neuropsychiatric and cognitive issues can develop and progress after TBI. We and others have provided novel evidence that these complications are potentiated by repeated injuries, immune challenges and stressors.

Priming the inflammatory pump of the CNS after traumatic brain injury.

Traumatic brain injury (TBI) can lead to secondary neuropsychiatric problems that develop and persist years after injury. Mounting evidence indicates that neuroinflammatory processes progress after the initial head injury and worsen with time. Microglia contribute to this inflammation by maintaining a primed profile long after the acute effects of the injury have dissipated.

Impact of late fluid balance on clinical outcomes in the critically ill surgical and trauma population.

Purpose: Management of fluid status in critically ill patients poses a significant challenge due to limited literature. This study aimed to determine the impact of late fluid balance management after initial adequate fluid resuscitation on in-hospital mortality for critically ill surgical and trauma patients.

Materials And Methods: This single-center retrospective cohort study included 197 patients who underwent surgical procedure within 24 hours of surgical intensive care unit admission.

Pre-injury beta blocker use does not affect the hyperdynamic response in older trauma patients.

Purpose: Trauma dogma dictates that the physiologic response to injury is blunted by beta-blockers and other cardiac medications. We sought to determine how the pre-injury cardiac medication profile influences admission physiology and post-injury outcomes.

Materials And Methods: Trauma patients older than 45 evaluated at our center were retrospectively studied.

Methylene blue attenuates traumatic brain injury-associated neuroinflammation and acute depressive-like behavior in mice.

Traumatic brain injury (TBI) is associated with cerebral edema, blood brain barrier breakdown, and neuroinflammation that contribute to the degree of injury severity and functional recovery. Unfortunately, there are no effective proactive treatments for limiting immediate or long-term consequences of TBI. Therefore, the objective of this study was to determine the efficacy of methylene blue (MB), an antioxidant agent, in reducing inflammation and behavioral complications associated with a diffuse brain injury.

Results of a prospective, randomized, controlled study of the use of carboxymethylcellulose sodium hyaluronate adhesion barrier in trauma open abdomens.

Introduction: The open abdominal (OA) approach is a management strategy used in the most severely injured trauma patients. In addition to the morbidity and mortality, a major challenge is the gradual development of dense adhesions that make reoperations progressively more difficult. This randomized, prospective, proof-of-concept study was conducted to determine the effect of carboxymethylcellulose sodium hyaluronate adhesion barrier (CMHAB; Seprafilm, Genzyme Biosurgery, Bridgewater, NJ) on abdominal adhesions and wound characteristics in trauma open abdomens.

Two Methods of Hemodynamic and Volume Status Assessment in Critically Ill Patients: A Study of Disagreement.

Introduction: The invasive nature and potential complications associated with pulmonary artery (PA) catheters (PACs) have prompted the pursuit of less invasive monitoring options. Before implementing new hemodynamic monitoring technologies, it is important to determine the interchangeability of these modalities. This study examines monitoring concordance between the PAC and the arterial waveform analysis (AWA) hemodynamic monitoring system.

Prospective evaluation of intravascular volume status in critically ill patients: does inferior vena cava collapsibility correlate with central venous pressure?

Background: In search of a standardized noninvasive assessment of intravascular volume status, we prospectively compared the sonographic inferior vena cava collapsibility index (IVC-CI) and central venous pressures (CVPs). Our goals included the determination of CVP behavior across clinically relevant IVC-CI ranges, examination of unitary behavior of IVC-CI with changes in CVP, and estimation of the effect of positive end-expiratory pressure (PEEP) on the IVC-CI/CVP relationship.

Methods: Prospective, observational study was performed in surgical/medical intensive care unit patients between October 2009 and July 2013.

Anion gap as a predictor of trauma outcomes in the older trauma population: correlations with injury severity and mortality.

The relationship among traumatic injury, the associated metabolic/physiologic responses, and mortality is well established. Tissue hypoperfusion and metabolic derangement may not universally correlate with initial clinical presentation. We hypothesized that anion gap (AG) could be a useful gauge of trauma-related physiologic response and mortality in older patients with relatively lower injury acuity.

Comorbidity-polypharmacy score: a novel adjunct in post-emergency department trauma triage.

Objective: Post-emergency department triage of older trauma patients continues to be challenging, as morbidity and mortality for any given level of injury severity tend to increase with age. The comorbidity-polypharmacy score (CPS) combines the number of pre-injury medications with the number of comorbidities to estimate the severity of comorbid conditions. This retrospective study examines the relationship between CPS and triage accuracy for older (≥45y) patients admitted for traumatic injury.

Real-time myocardial glucose measurement using biosensors.

During ischemia, myocardial fatty acid metabolism ceases, rapidly depleting the other primary fuel, glucose. No technique has existed to continuously monitor myocardial glucose. Needle-tip enzymatic glucose biosensors have been developed for subcutaneous use in diabetic management.
