Sepsis, hemorrhagic shock,

The modification of nuclear, cytoplasmic, and mitochondrial proteins by O-linked β-N-acetylglucosamine (O-GlcNAc) is an essential post-translational modification common in metazoans. O-GlcNAc is cycled on and off proteins in response to environmental and physiological stimuli impacting protein function, which, in turn, tunes pathways that include transcription, translation, proteostasis, signal transduction, and metabolism. One class of stimulus that induces rapid and dynamic changes to O-GlcNAc is cellular injury, resulting from environmental stress (for instance, heat shock), hypoxia/reoxygenation injury, ischemia reperfusion injury (heart attack, stroke, trauma hemorrhage), and sepsis...

BACKGROUND: Postpartum hemorrhage (PPH) and post-abortion hemorrhage (PAH) are life-threatening conditions. PURPOSE: To evaluate the efficacy and safety of uterine arterial embolization (UAE) for PPH and PAH and to investigate future fertility after UAE. MATERIAL AND METHODS: This study included 57 consecutive patients (mean age = 34 years) who underwent UAE for PPH (n = 46) and PAH (n = 11) at our institution between January 2011 and December 2022...

OBJECTIVE: The stability of hemodynamics plays a vital role in the process of anesthesia induction for patients with septic shock. As a new-type benzodiazepine, remimazolam has numerous advantages, including rapid induction, rapid recovery, stable hemodynamics, and mild respiratory depression. Nevertheless, reports about the effects of remimazolam on hemodynamics in patients with septic shock are still limited. The study aimed to evaluate the effects that different doses of remimazolam have on hemodynamics in inducing general anesthesia in patients with septic shock...

OBJECTIVE: Among critically injured patients of various blood groups, we sought to compare survival and complication rates between COVID-19-positive and COVID-19-negative cohorts. BACKGROUND: SARS-CoV-2 infections have been shown to cause endothelial injury and dysfunctional coagulation. We hypothesized that, among patients with trauma in hemorrhagic shock, COVID-19-positive status would be associated with increased mortality and inpatient complications. As a secondary hypothesis, we suspected group O patients with COVID-19 would experience fewer complications than non-group O patients with COVID-19...

Severe burn injury elicits a profound stress response with the potential for high morbidity and mortality. If polytrauma is present, patient outcomes appear to be worse. Sex-based comparisons indicate females have worse outcomes than males. There are few effective drug therapies to treat burn shock and secondary injury progression. The lack of effective drugs appears to arise from the current treat-as-you-go approach rather than a more integrated systems approach. In this review, we present a brief history of burns research and discuss its pathophysiology from a systems' perspective...

BACKGROUND: Previous preclinical studies have demonstrated sex-specific alterations in the gut microbiome following traumatic injury or sepsis alone; however, the impact of host sex on dysbiosis in the setting of postinjury sepsis acutely is unknown. We hypothesized that multicompartmental injury with subsequent pneumonia would result in host sex-specific dysbiosis. METHODS: Male and proestrus female Sprague-Dawley rats (n = 8/group) were subjected to either polytrauma (PT) (lung contusion, hemorrhagic shock, cecectomy, bifemoral pseudofracture), PT plus 2-hours daily restraint stress (PT/RS), PT with postinjury day 1 pseudomonas aeruginosa pneumonia (PT + PNA), PT/RS with pneumonia (PT/RS + PNA), or naive controls...

Waterhouse-Friderichsen syndrome is a rare but potentially fatal disorder of the adrenal gland characterized by bilateral adrenal hemorrhage. It is classically a result of meningococcal sepsis and presents acutely with features of shock, petechial rashes, abdominal pain, and non-specific symptoms such as headache, fatigue, and vomiting. Treatment consists of fluid resuscitation, corticosteroid replacement, and possibly surgery. The prognosis is poor despite treatment. This chapter will review the etiology, pathogenesis, clinical features, and management of the disease...

Magnesium hydride (MgH2 ) is a hydrogen storage material that is known for its high capacity and safety and is capable of releasing hydrogen in a controlled manner when administered orally. This release of hydrogen has been associated with a range of biological effects, including anti-inflammatory properties, antioxidant activity, and protection of the intestinal barrier. Previous research has shown that neutrophil extracellular traps (NETs) play a role in the dysfunction of the intestinal barrier in conditions such as sepsis and critical illnesses...

Arterial-enteric fistulas occur from a multitude of causes, especially following surgical manipulation of vasculature. The development of an iliac artery-enteric fistula (IEF) occurs rarely in patients with failed pancreatic transplants. IEFs warrant urgent intervention due to the high mortality from hemorrhagic and septic shock. The diagnosis can be delayed by a lack of suspicion, the low sensitivity of diagnostic tests, and the nonspecific signs of fistulas on computed tomography. The management of IEFs is adapted from guidelines for arterial-enteric fistulas of other causes, with little consensus on ideal vascular reconstruction and postoperative antimicrobial management...

BACKGROUND AND OBJECTIVE: Plasma is a critical element in hemostatic resuscitation post-injury, and its prompt administration within the prehospital setting may reduce the complications resulting from hemorrhage and shock. Our objective is to assess the efficacy and safety of prehospital plasma infusion in patients susceptible to hemorrhagic shock. METHODS: We conducted our study by aggregating randomized controlled trials (RCTs) sourced from PubMed, EMBASE, Scopus, Web of Science, and Cochrane CENTRAL up to January 29, 2023...

Resuscitative endovascular balloon occlusion of the aorta (REBOA) has become part of the arsenal to temporize patients in shock from severe hemorrhage. REBOA is used in trauma to prevent cardiovascular collapse by preserving heart and brain perfusion and minimizing distal hemorrhage until definitive hemorrhage control can be achieved. Significant side effects, including death, ischemia and reperfusion injuries, severe renal and lung damage, limb ischemia and amputations have all been reported. The aim of this article is to provide an update on complications related to REBOA...

Patients with inflammatory bowel disease can present with numerous infectious complications, including intra-abdominal abscess, perforations of the intestine, fistula formation, and the occurrence of septicemia. Toxic megacolon (TM) is a potentially fatal complication of inflammatory bowel disease (IBD) and is associated with high morbidity and mortality. In this case report, we report a 49-year-old male patient who was admitted to the intensive care unit for the management of severe sepsis that was secondary to an inaugural toxic megacolon complicating a silent inflammatory bowel disease, with a Lichtiger score of 11...

PURPOSE: The goal is to identify risk factors associated with receiving a blood transfusion during the perioperative period in patients who undergo total laparoscopic hysterectomy (TLH) using a large-scale national database. METHODS: In this retrospective analysis, data from the Nationwide Inpatient Sample (NIS) was utilized to review the medical records of all patients who underwent TLH from 2010 to 2019. The researchers identified patients who had received a blood transfusion during the perioperative period and compared with those who had not...

UNLABELLED: This randomized controlled trial aimed to determine whether lung ultrasound-guided fluid resuscitation improves the clinical outcomes of neonates with septic shock. Seventy-two patients were randomly assigned to undergo treatment with lung ultrasound-guided fluid resuscitation (LUGFR), or with usual fluid resuscitation (Control) in the first 6 h since the start of the sepsis treatment. The primary study outcome was 14-day mortality after randomization. Fourteen-day mortalities in the two groups were not significantly different (LUGFR group, 13...

INTRODUCTION: Fibrinogen and platelet, as the two main components of hemostatic resuscitation, are frequently administered in traumatic massive hemorrhage patients. It is reasonable to infer that they may have an impact on post-traumatic sepsis as more and more recognition of their roles in inflammation and immunity. This study aims to determine the association between the fibrinogen/platelet transfusion ratio during the first 24 h after trauma and the risk of the post- traumatic sepsis...

INTRODUCTION: Expected future delays in evacuation during near-peer conflicts in remote locales are expected to require extended care including prolonged field care over hours to days. Such delays can increase potential complications, such as insufficient blood flow (shock), bloodstream infection (sepsis), internal bleeding (hemorrhage), and require more complex treatment beyond stabilization. The Trauma Triage Treatment and Training Decision Support (4TDS) system is a real-time decision support system to monitor casualty health and identify such complications...

In this case report, we describe the clinical course of a complicated transplant renal artery (TRA) pseudoaneurysm, clinically featured by gross and massive hematuria one month after a kidney transplant was performed on a 50 year-old male patient. TRA pseudoaneurysm is a rare but potentially life-threatening complication that may result in bleeding, infection, graft dysfunction/loss, lower limb ischemia/loss, hemorrhagic shock, and death. TRA pseudoaneurysm treatment remains challenging as it needs to be tailored to the patient characteristics including hemodynamic stability, graft function, anatomy, presentation, and pseudoaneurysm features...

Waterhouse-Friderichsen syndrome and central diabetes insipidus are uncommon but potentially fatal endocrine and metabolic diseases. Waterhouse-Friderichsen syndrome is defined as adrenal insufficiency caused by adrenal hemorrhage, which is typically bilateral and most frequently due to meningococcal infection. It is usually diagnosed by necropsy. Central diabetes insipidus in children is often caused by trauma, intracranial lesions, autoimmune diseases, and infections. In addition, it can be caused by mutations in the AVP-NPII gene, although this occurs typically later in childhood rather than in the neonatal period...

BACKGROUND: Recent studies have shown that ferroptosis is involved in the evolution of acute lung injury (ALI), a serious respiratory pathological process leading to death. However, the regulatory mechanisms underlying ferroptosis in ALI remain largely unknown. The current study analyzed and identified a ferroptosis-related gene signature for ALI. METHODS: Key genes associated with ferroptosis in ALI were identified by bioinformatics analysis. GSE104214, GSE18341, and GSE17355 datasets were downloaded from the Gene Expression Omnibus database...

Background: Plasma is commonly used in patients with coagulopathy; however, its role in patients with sepsis-induced coagulopathy (SIC) is unclear. This study aimed to evaluate the effect of plasma transfusion on the prognosis of patients with SIC. Methods: Data were collected from the Medical Information Mart for Intensive Care IV database. Multivariable logistic regression analysis was used to determine the association between plasma transfusion and the incidence of in-hospital mortality, pulmonary embolism, and lower extremity deep vein thrombosis in critically ill patients with SIC...
