Evaluating predictors of mortality in octogenarians undergoing urgent or emergent trauma laparotomy.

Purpose: This study aimed to identify associated risk factors for mortality in octogenarian trauma patients undergoing urgent or emergent laparotomy (UEL).

Methods: Trauma patients ages 80-89 years-old undergoing UEL within 6-hours of arrival were included. A multivariable logistic regression analysis was performed to determine associated risk of mortality.

Surgical Care Through a Community Free Clinic-Ambulatory Surgical Center Partnership.

Background: Disparities secondary to underinsurance present throughout the surgical care continuum. Community free clinics are uniquely capable to provide health care services to the medically underserved, but surgery often falls outside their scope of care.

Methods: Retrospective chart review was conducted on consecutive community free clinic patients receiving free surgical services via referral to a partnering ambulatory surgery center between March 2016 and September 2021.

Blunt Adrenal Injury is Not Associated With Worse Outcomes in Adult Trauma Patients.

Introduction: Blunt adrenal injury is rare. Given production of hormones including catecholamines, adrenal injury may lead to worse outcomes. However, there is a paucity of literature on this topic.

Adolescent Trauma Patients With Isolated Head Trauma and Glasgow Coma Scale 6-8: Routine Intubation?

Background: Recent evidence suggests that routine intubation upon arrival for adults with isolated head trauma and a depressed Glasgow Coma Scale (GCS) score is associated with increased risk of morbidity and mortality. Whether these outcomes are similar within an adolescent trauma population has not been previously investigated. We hypothesized intubation upon arrival for adolescent trauma patients with isolated head trauma to be associated with a higher risk of death and prolonged length of stay (LOS).

Firearm Violence Involving Adults 65 and Older During the Novel Coronavirus Disease Pandemic.

Background: Rates of firearm violence (FV) surged during the COVID-19 pandemic. However, there is a paucity of data regarding older adults (OAs) (≥65 years old). This study aimed to evaluate patterns of FV against OAs before and after the COVID-19 pandemic, hypothesizing decreased firearm incidents, injuries, and deaths for OAs due to restricted social movement.

Clinical Outcome Comparison of Patients Requiring Extracorporeal Membrane Oxygenation With or Without COVID-19 Infection.

In severe COVID-19-related respiratory failure, extracorporeal membrane oxygenation (ECMO) is a useful modality that is used to provide effective oxygenation and ventilation to the patient. This descriptive study aimed to investigate and compare the outcomes between COVID-19-infected patients and patients who were not infected and required ECMO support. A retrospective study was undertaken on a cohort of 82 adult patients ([Formula: see text]18-year-old) who required venoarterial (VA-ECMO) and venovenous (VV-ECMO) ECMO between January 2019 and December 2022 in a single academic center.

Perceptions of nonopioid treatment for pain in a homeless population.

Context: Opioid abuse has developed into a public health emergency within the last decade because opioid medications, while addictive, are effective and commonly used for pain management. In 2016, over 42,000 deaths were attributed to opioids. Chronic pain affects about 50% of people experiencing homelessness in the US, and they have a higher overall rate of chronic pain than the general population; opioids are among the methods they might use to manage that pain.

Enhancing Antitumor Efficacy of Heavily Vascularized Tumors by RAMBO Virus through Decreased Tumor Endothelial Cell Activation.

Vascularization is a common pathology for many solid tumors, and therefore anti-angiogenic strategies are being investigated as a therapeutic target for treatment. Numerous studies are also being conducted regarding the effects of oncolytic viruses, including Imlygic, an FDA approved oncolytic herpes simplex virus-1 (oHSV) for the treatment of highly vascularized tumors such as Kaposi sarcoma (NCT04065152), and brain tumors. To our knowledge, the effects of combining oncolytic HSV with angiogenesis inhibition on endothelial cell activation has not been previously described.

Responses of cerebral blood velocity and tissue oxygenation to low-frequency oscillations during simulated haemorrhagic stress in humans.

New Findings: What is the central question of this study? Do low-frequency oscillations in arterial pressure and cerebral blood velocity protect cerebral blood velocity and oxygenation during central hypovolaemia? What is the main finding and its importance? Low-frequency oscillations in arterial pressure and cerebral blood velocity attenuate reductions in cerebral oxygen saturation but do not protect absolute cerebral blood velocity during central hypovolaemia. This finding indicates the potential importance of haemodynamic oscillations in maintaining cerebral oxygenation and therefore viability of tissues during challenges to cerebral blood flow and oxygen delivery.

Abstract: Tolerance to both real and simulated haemorrhage varies between individuals.

Oncolytic HSV therapy increases trametinib access to brain tumors and sensitizes them in vivo.

Background: Hyperactivation of the RAS-RAF-MEK-ERK signaling pathway is exploited by glioma cells to promote their growth and evade apoptosis. MEK activation in tumor cells can increase replication of ICP34.5-deleted herpes simplex virus type 1 (HSV-1), but paradoxically its activation in tumor-associated macrophages promotes a pro-inflammatory signaling that can inhibit virus replication and propagation.

Hemorrhage simulated by lower body negative pressure provokes an oxidative stress response in healthy young adults.

We characterize the systemic oxidative stress response in young, healthy human subjects with exposure to simulated hemorrhage via application of lower body negative pressure (LBNP). Prior work has demonstrated that LBNP and actual blood loss evoke similar hemodynamic and immune responses (i.e.
