Background: Identification of positive lymph nodes in colon cancer can significantly impact treatment. Few studies have examined the role of lymph node size in staging and prognosis. This study evaluated the relationship between lymph node size and lymph node metastases in right-sided colon cancer.

Background: The prevalence of patients with end stage renal disease (ESRD) requiring general surgical procedures is increasing. Our aim was to explore the effect of ESRD on patients undergoing elective laparoscopic ventral hernia repair.

Methods: The American College of Surgeons National Surgical Quality Improvement Program (2010-2015) database was used to identify patients who underwent elective laparoscopic ventral hernia repair.

Extracellular cold-inducible RNA-binding protein (eCIRP) induces acute lung injury (ALI) in sepsis. Triggering receptor expressed on myeloid cells-1 (TREM-1) serves as a receptor for eCIRP to induce inflammation in macrophages and neutrophils. The effect of eCIRP on alveolar epithelial cells (AECs) remains unknown.

Background: Extracellular cold-inducible RNA-binding protein (eCIRP) is a damage-associated molecular pattern, which is released into the circulation after hemorrhagic shock (HS). Recently, we discovered that triggering receptor expressed on myeloid cells-1 (TREM-1) serves as a new receptor of eCIRP to exaggerate inflammation. Here, we hypothesize that by inhibiting the interaction between eCIRP and TREM-1 with the use of a novel short peptide derived from human eCIRP known as M3, we can inhibit the inflammatory response and acute lung injury in HS.

Extracellular cold-inducible RNA-binding protein (eCIRP) is a recently discovered damage-associated molecular pattern. Understanding the precise mechanism by which it exacerbates inflammation is essential. Here we identified that eCIRP is a new biologically active endogenous ligand of triggering receptor expressed on myeloid cells-1 (TREM-1), fueling inflammation in sepsis.

Sepsis is a deadly inflammatory syndrome caused by an exaggerated immune response to infection. Much has been focused on host response to pathogens mediated through the interaction of pathogen-associated molecular patterns (PAMPs) and pattern recognition receptors (PRRs). PRRs are also activated by host nuclear, mitochondrial, and cytosolic proteins, known as damage-associated molecular patterns (DAMPs) that are released from cells during sepsis.

Although microRNAs regulate mRNA expression intracellularly, they are often released into the circulation in inflammatory diseases. During sepsis, secreted extracellular cold-inducible RNA-binding protein (eCIRP) acts as a damage-associated molecular pattern (DAMP), inducing tissue damage by elevating inflammatory cytokines and chemokines. Here, we report that the circulating microRNA 130b-3p inhibits eCIRP-mediated sterile and cecal ligation and puncture (CLP)-induced non-sterile inflammation.

Aortoenteric fistulas are an uncommon cause of gastrointestinal bleeding, and iliac-appendiceal fistulas are an even rarer cause. We describe a case of an iliac-appendiceal fistula in a patient who presented several months after aortic reconstruction with gastrointestinal bleeding. An extensive workup revealed that the source of bleeding was localized to the appendiceal orifice.

Introduction: Specialized knowledge and a scientific body of literature are the foundation of the recognition of Emergency Medical Services (EMS) as a subspecialty within emergency medicine (EM). Emergency Medical Services research often is presented at national meetings and published in abstract form, but full publication occurs less frequently. Problem The primary goal of the study was to determine the rate at which EMS-related research presented at selected conferences went on to manuscript publication.

Synopsis of recent research by authors named "Steven Gurien"

  • - Steven Gurien's recent research primarily focuses on the relationship between molecular mechanisms and clinical outcomes in surgical settings and sepsis, particularly investigating how proteins and peptides influence inflammation and recovery processes in patients.
  • - His studies have explored the implications of lymph node size on metastatic disease in colon cancer, as well as complications arising from laparoscopic procedures in patients with end-stage renal disease, suggesting a critical need for tailored approaches in these populations.
  • - Gurien has also contributed significantly to understanding the role of extracellular cold-inducible RNA-binding protein (eCIRP) in exacerbating inflammation during sepsis, identifying its interactions with receptors like TREM-1, and the potential for therapeutic intervention through peptide inhibitors.
