Differential Effects of GLP-1 Receptor Agonists on Cancer Risk in Obesity: A Nationwide Analysis of 1.1 Million Patients.

: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have demonstrated significant efficacy in obesity treatment beyond their original development for type-2 diabetes management. This comprehensive study investigated the relationship between GLP-1RA use and cancer incidence in individuals with obesity across a 5-year follow-up period. : We conducted a large-scale cohort study using the TriNetX US Collaborative Network database (2013-2023) examining adult patients with obesity.

Stop the Bleed-Wait for the Ambulance or Get in the Car and Drive? A Post Hoc Analysis of an EAST Multicenter Trial.

The Stop the Bleed campaign gives bystanders an active role in prehospital hemorrhage control. Whether extending bystanders' role to private vehicle transport (PVT) for urban penetrating trauma improves survival is unknown, but past research has found benefit to police and PVT. We hypothesized that for penetrating trauma in an urban environment, where prehospital procedures have been proven harmful, PVT improves outcomes compared to any EMS or advanced life support (ALS) transport.

Resuscitative endovascular balloon occlusion of the aorta in the patient with obesity.

Background: Palpation of anatomic landmarks is difficult in patients with obesity, which could increase difficulty of achieving femoral access and resuscitative endovascular balloon occlusion of the aorta (REBOA) placement. The primary aim of this study was to examine the association between obesity and successful REBOA placement. We hypothesized that higher body mass index (BMI) would decrease first-attempt success and increase time to successful aortic occlusion (AO).

Firearm Homicide Mortality is Linked to Food Insecurity in Major US Metropolitan Cities.

Background: Gun violence disproportionately affects metropolitan areas of the United States (US). There is limited information regarding the influence of social determinants of health, such as food insecurity (FI) on firearm homicide mortality (FHM) in major metropolitan cities in the US. We sought to examine the relationship between FI and FHM.

Single Chelator-Minibody Theranostic Agents for Zr PET Imaging and Lu Radiopharmaceutical Therapy of PSMA-Expressing Prostate Cancer.

Here we describe an anti-prostate-specific membrane antigen (PSMA) minibody (IAB2MA) conjugated to an octadentate, macrocyclic chelator based on four 1-hydroxypyridin-2-one coordinating units (Lumi804 [L804]) labeled with Zr (PET imaging) and Lu (radiopharmaceutical therapy), with the goal of developing safer and more efficacious treatment options for prostate cancer. L804 was compared with the current gold standard chelators, DOTA and deferoxamine (DFO), conjugated to IAB2MA for radiolabeling with Lu and Zr in cell binding, preclinical biodistribution, imaging, dosimetry, and efficacy studies in the PSMA-positive PC3-PIP tumor-bearing mouse model of prostate cancer. Quantitative radiolabeling (>99% radiochemical yield) of L804-IAB2MA with Lu or Zr was achieved at ambient temperature in under 30 min, comparable to Zr labeling of DFO-IAB2MA.

Tranexamic Acid and Pulmonary Complications: A Secondary Analysis of an EAST Multicenter Trial.

Background: Anti-inflammatory effects of tranexamic acid (TXA) in reducing trauma endotheliopathy may protect from acute lung injury. Clinical data showing this benefit in trauma patients is lacking. We hypothesized that TXA administration mitigates pulmonary complications in penetrating trauma patients.

Every minute matters: Improving outcomes for penetrating trauma through prehospital advanced resuscitative care.

Background: Prehospital resuscitation with blood products is gaining popularity for patients with traumatic hemorrhage. The MEDEVAC trial demonstrated a survival benefit exclusively among patients who received blood or plasma within 15 minutes of air medical evacuation. In fast-paced urban EMS systems with a high incidence of penetrating trauma, mortality data based on the timing to first blood administration is scarce.

Impact of Prehospital Exsanguinating Airway-Breathing-Circulation Resuscitation Sequence on Patients with Severe Hemorrhage.

Background: At the 2023 ATLS symposium, the priority of circulation was emphasized through the "x-airway-breathing-circulation (ABC)" sequence, where "x" stands for exsanguinating hemorrhage control. With growing evidence from military and civilian studies supporting an x-ABC approach to trauma care, a prehospital advanced resuscitative care (ARC) bundle emphasizing early transfusion was developed in our emergency medical services (EMS) system. We hypothesized that prioritization of prehospital x-ABC through ARC would reduce in-hospital mortality.

Faster refill in an urban emergency medical services system saves lives: A prospective preliminary evaluation of a prehospital advanced resuscitative care bundle.

Introduction: Military experience has demonstrated mortality improvement when advanced resuscitative care (ARC) is provided for trauma patients with severe hemorrhage. The benefits of ARC for trauma in civilian emergency medical services (EMS) systems with short transport intervals are still unknown. We hypothesized that ARC implementation in an urban EMS system would reduce in-hospital mortality.

PROSPECTIVE EXAMINATION OF THE K/ICA RATIO AS A PREDICTOR FOR MORTALITY IN SEVERE HEMORRHAGE.

Background: Patients receiving massive transfusion protocol (MTP) are at risk for posttransfusion hypocalcemia and hyperkalemia. Previous retrospective analysis has suggested the potassium/ionized calcium (K/iCa) ratio as a prognostic indicator of mortality. This prospective study sought to validate the value of the K/iCa ratio as a predictor for mortality in patients receiving MTP.

Tropical Storms and Hurricanes in New Orleans Lead to Increased Rates of Violent Injury.

Objective: The effects of named weather storms on the rates of penetrating trauma is poorly understood with only case reports of single events currently guiding public health policy. This study examines whether tropical storms and hurricanes contribute to trauma services and volume.

Methods: This was a cross-sectional review of tropical storms/hurricanes affecting New Orleans, Louisiana, during hurricane seasons (June 1-November 30) from 2010-2021, and their association with the rate of penetrating trauma.

Nutritional Considerations for Patients With Renal Failure Undergoing Sleeve Gastrectomy.

Obesity is highly prevalent in patients with renal disease, as it contributes to or accelerates the progression of kidney disease and is frequently a barrier to kidney transplantation. Patients with renal disease have unique dietary needs due to various metabolic disturbances resulting from altered processing and clearance of nutrients. They also frequently present with physical disability, resulting in difficulty achieving adequate weight loss through lifestyle modifications.

Association Between Markers of Structural Racism and Mass Shooting Events in Major US Cities.

Importance: The root cause of mass shooting events (MSEs) and the populations most affected by them are poorly understood.

Objective: To examine the association between structural racism and mass shootings in major metropolitan cities in the United States.

Design, Setting, And Participants: This cross-sectional study of MSEs in the 51 largest metropolitan statistical areas (MSAs) in the United States analyzes population-based data from 2015 to 2019 and the Gun Violence Archive.

Trends in Maternal Mortality and Severe Maternal Morbidity During Delivery-Related Hospitalizations in the United States, 2008 to 2021.

Importance: Maternal mortality and severe maternal morbidity (SMM) are important focus areas in public health. Further understanding trends, health disparities, and risk factors for these adverse outcomes is vital to public health decision-making.

Objective: To describe trends and risk factors for delivery-related maternal deaths and SMM in the United States.

Balancing Waitlist Dropout in Pancreas Transplantation.

Background: The time a patient spends on the waiting list for a Simultaneous Pancreas-Kidney (SPK) transplant depends on several donor and recipient-specific factors. The average wait-list time for SPK in the United States has been about 1 to 3 years, significantly shorter than the average wait time for kidney-only transplantation. A single-center retrospective analysis of SPK waitlisted candidates was performed to determine the implication of wait-list time on dropout from the wait-list due to death or poor health.

Laparoscopic Living Donor Nephrectomy: A Single Center Comparison of Three Different Techniques.

Background And Objectives: In this study, we compare three different surgical approaches at a single institution. Pure laparoscopic donor nephrectomy with Pfannenstiel incision (PLDN) was compared with hand-assisted laparoscopic donor nephrectomy via midline hand port (HALDNM) and hand-assisted laparoscopic donor nephrectomy via left iliac hand port (HALDNL).

Methods: This study included all laparoscopic left donor nephrectomies performed at our institution between January 1, 2020 and December 31, 2021.

Traumatic Injury in Pregnancy: A Propensity Score-Matched Analysis.

Introduction: Trauma represents the leading cause of nonobstetrical maternal death. How in-hospital outcomes of acutely injured pregnant patients (PP) compares to that of similarly aged nonpregnant control groups (CGs) has not been described. We hypothesized that PPs suffering acute traumatic injuries would have worse outcomes compared to a matched CG.

Kidney Transplant Outcomes in Recipients Over the Age of 70.

Background: Patients older than 70 years are the fastest-growing age group of patients requiring renal replacement therapy. This has resulted in a corresponding increase in the number of elderly transplant recipients. We hypothesized that graft survival in this population would be comparable to that seen in the literature on kidney transplant recipients under 70 years of age.

Evidence of Downregulation in Atmospheric Nitrogen-Fixation Associated with Native Hawaiian Sugarcane ( L.) Cultivars.

The study of nitrogen fixation in sugarcane has a long history that has demonstrated high potential but with substantial variation in results. This 32-month study sought to assess the response of nitrogen fixation associated with sugarcane ( L. cvs.

Cost-Effectiveness of Universal Screening for Blunt Cerebrovascular Injury: A Markov Analysis.

Background: Blunt cerebrovascular injury (BCVI) is a significant cause of morbidity and mortality after blunt trauma. Numerous screening strategies exist, although which is used is institution- and physician-dependent. We sought to identify the most cost-effective screening strategy for BCVI, hypothesizing that universal screening would be optimal among the screening strategies studied.

IMPACT OF TIME TO EMERGENCY DEPARTMENT RESUSCITATIVE AORTIC OCCLUSION AFTER NONCOMPRESSIBLE TORSO HEMORRHAGE.

Introduction: Time is an essential element in outcomes of trauma patients. The relationship of time to treatment in management of noncompressible torso hemorrhage (NCTH) with resuscitative endovascular balloon occlusion of the aorta (REBOA) or resuscitative thoracotomy (RT) has not been previously described. We hypothesized that shorter times to intervention would reduce mortality.
