OBJECTIVE: To evaluate the efficacy and safety of using angiotensin II (Ang2) as primary vasopressor for vasodilatory hypotension. METHODS: This was a prospective observational study of critically ill adults admitted to an academic Intensive Care Unit (ICU) with vasodilatory hypotension. We treated 40 patients with Ang2 as primary vasopressor and compared them to 80 matched controls who received conventional vasopressors (norepinephrine, vasopressin, metaraminol, epinephrine, or combinations)...

BACKGROUND: Systemic inflammation act as a contributor to neurologic deficits after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). Extracellular cold-inducible RNA-binding protein (CIRP) has been demonstrated to be responsible in part for the inflammation through binding to Toll-like receptor 4 (TLR4) after cerebral ischemia. The short peptide C23 derived from CIRP has a high affinity for TLR4, we hypothesize that C23 reduces systemic inflammation after CA/CPR by blocking the binding of CIRP to TLR4...

Sepsis-induced cardiomyopathy (SIC) is one of the most common complications of infection-induced sepsis. An imbalance in inflammatory mediators is the main factor leading to SIC. N6-methyladenosine (m6A) is closely related to the occurrence and development of sepsis. m6A reader YTH Domain Containing 1 (YTHDC1) is an m6A N6-methyladenosine recognition protein. However, the role of YTHDC1 in SIC remains unclear. Herein, we demonstrated that YTHDC1-shRNA inhibits inflammation, reduces inflammatory mediators, and improves cardiac function in a lipopolysaccharide (LPS)-induced SIC mouse model...

Acute respiratory distress syndrome (ARDS) is characterized by uncontrolled inflammation, which manifests as leukocyte infiltration and lung injury. However, the molecules that initiate this infiltration remain incompletely understood. We evaluated the effect of the nuclear alarmin interleukin (IL)-33 on lung damage and the immune response in lipopolysaccharide (LPS)-induced lung injury. We established a lipopolysaccharide (LPS)-induced lung injury mouse model. We used genetically engineered mice to investigate the relationship among the IL-33/ST2 axis, NKT cells, and ARDS...

BACKGROUND: Infantile pneumonia is a respiratory infection disease, seriously threatening the life of neonatal patients. Circular RNA (circRNA) dysregulation is reported to be involved in pneumonia pathogenesis. Circ_0012535 was previously displayed to be upregulated in blood samples of patients with community-acquired pneumonia. However, circ_0012535's role in this disorder remains unclear. We thus aim to unveil the functions of circ_0012535 in infantile pneumonia. METHODS: Fetal lung fibroblasts (WI38) treated with lipopolysaccharide (LPS) were used as pneumonia cell models...

OBJECTIVES: Systemic ischemia-reperfusion triggered by cardiac arrest (CA) and resuscitation often causes post-resuscitation multiple organ injuries. Mesenchymal stem cells (MSCs) have been proven to be a promising treatment for regional renal and intestinal ischemia reperfusion injuries. This study aimed to investigate the effects of MSCs on renal and intestinal injuries following cardiopulmonary resuscitation (CPR) in a porcine CA model.

BACKGROUND: Immunosuppression caused by immune cell apoptosis and an imbalance of T help 2 cells (Th2) and T help 1 cells (Th1), is associated with poor outcomes in septic patients. Esmolol was reported to improve survival by modulating immune responses in septic shock. Whether Esmolol could alleviate sepsis-induced immunosuppression and the optimal dose are unclear. METHODS: Four hours after cecal ligation and puncture (CLP), Wistar rats were randomized into CLP, CLP + E-5 (Esmolol:5 mg...

INTRODUCTION: Cell-free DNA (CFDNA) has emerged as a prognostic biomarker in patients with sepsis. Circulating CFDNA is hypothesized to be associated with histones in the form of nucleosomes. In vitro, DNA activates coagulation and inhibits fibrinolysis, whereas histones activate platelets and are cytotoxic to endothelial cells. Previous studies have targeted CFDNA or histones in animal models of sepsis using DNase I or heparins, respectively, which has reduced inflammatory and thrombosis markers, thereby improving survival...

A solution of high concentration albumin has been used for temporal volume expansion when timely resuscitation was unavailable following hemorrhagic shock. However, during prolonged hemorrhagic shock, cell edema and interstitial dehydration can occur and impede the volume expansion effect of albumin. Polyethylene glycol-20 K (PEG) can establish an osmotic gradient from swollen cells to capillary lumens and thus facilitate capillary fluid shift and volume expansion. We hypothesized that, with similar osmolality, 7...

INTRODUCTION: Sepsis is a dysregulated host response to infection that can lead to life-threatening organ dysfunction. Clinical and animal studies consistently demonstrate that female subjects are less susceptible to the adverse effects of sepsis, demonstrating the importance of understanding how sex influences sepsis outcomes. The signal transducer and activator of transcription 3 (STAT3) pathway is a major signaling pathway that facilitates inflammation during sepsis. STAT3 is abundantly expressed in white adipose tissue, however little is known about the contribution of white adipose tissue STAT3 activation during sepsis...

BACKGROUND: Hemorrhagic shock-induced acute lung injury (ALI) is commonly associated with the post-hemorrhagic shock mesenteric lymph (PHSML) return. Whether excessive autophagy is involved in PHSML-mediated ALI remains unclear. The relationship between estrogen treatment and PHSML or autophagy needs to verify. The current study will clarify the role of estrogen in reducing PHSML-mediated ALI through inhibition of autophagy. METHODS: Firstly, a hemorrhagic shock model in conscious rats was employed to observe the effects of 17β-estradiol (E2) on intestinal blood flow, pulmonary function, intestinal and pulmonary morphology, and expression of autophagy marker proteins...

BACKGROUND: Mortality in cardiogenic shock (CS) is up to 40%, and although risk scores have been proposed to stratify and assess mortality in CS, they have been shown to have inconsistent performance. The purpose was to compare CS prognostic scores and describe their performance in a real-world Latin American country. METHODS: We included 872 patients with CS. SCAI, CARDSHOCK, IABP-Shock II, CSS, ALC, GWTG-HF, and ADHERE scores were calculated. Decision curve analyses were performed to evaluate the net benefit of the different scoring systems...

Pulmonary epithelial barrier injury contributes to acute lung injury, accelerating exudate formation, and resulting alveolar edema. Heme oxygenase-1 (HO-1) plays an important role in ameliorating the pathological symptoms of acute lung injury (ALI). Using an ALI mouse model induced by lipopolysaccharide (LPS) inhalation, the present study explored the potential molecular regulatory effect of hemin (a potent HO-1 inducer) against ALI epithelial damage. LPS challenge triggered dysfunction of the alveolar epithelial barrier, impaired tight junctions and disrupted alveoli fluid clearance, while these pathological changes were effectively reversed by hemin treatment...

While fluid resuscitation is fundamental in the treatment of sepsis-induced tissue hypo-perfusion, a sustained positive fluid balance is associated with excess mortality. Hyaluronan, an endogenous glycosaminoglycan with high affinity to water, has not been tested previously as adjuvant to fluid resuscitation in sepsis.In a prospective, parallel-grouped, blinded model of porcine peritonitis-sepsis, we randomized animals to intervention with adjuvant hyaluronan (add-on to standard therapy) (n = 8) or 0.9% saline (n = 8)...
