In this 4-month-long prospective observational study, we explored the colonization rate of extended-spectrum β-lactamase-producing (ESBL-EC) in the patient and ward environment of an intensive care unit (ICU). Additionally, we evaluated the risk factors for colonization and analyzed genomic characteristics and modes of transmission of isolates. Clinical samples were collected from patients and the environment to isolate and screen strains.

Severe acute pancreatitis (SAP) is a critical condition characterized by an imbalance between systemic inflammatory response syndrome (SIRS) and compensatory anti-inflammatory response syndrome (CARS). Disruptions in intestinal microbiota exacerbate this imbalance; however, the mechanisms by which commensal bacteria regulate SAP-induced SIRS and/or CARS remain unclear. This study reports that the abundance of the gut commensal Akkermansia is significantly reduced in fecal samples from patients with acute pancreatitis (AP) and is inversely associated with the severity of systemic inflammatory responses.

Introduction: Severe acute pancreatitis (SAP) is a crucial gastrointestinal disease characterized by systemic inflammatory responses and persistent multiple organ failure. The role of bile acids (BAs) in diverse inflammatory diseases is increasingly recognized as crucial, but the underlying role of BA conjugation remains elusive.

Objectives: Our study aim to investigate the potential role of conjugated bile acids in SAP and reveal the molecular mechanisms underlying its regulatory effects.

Acute pancreatitis (AP) is currently among the most prevalent digestive diseases. The pathogenesis of AP remains elusive, and there is no specific treatment. Therefore, identifying novel therapeutic targets is imperative for effective management and prevention of AP.

This 4-month-long prospective observational study investigated the epidemiological characteristics, genetic composition, transmission pattern, and infection control of carbapenem-resistant Escherichia coli (CREC) colonization in patients at an intensive care unit (ICU) in China. Phenotypic confirmation testing was performed on nonduplicated isolates from patients and their environments. Whole-genome sequencing was performed for all E.

Article Synopsis
  • * Research shows that specific beneficial bacteria and their metabolite, lactate, can help protect against SAP by reducing inflammation and improving survival rates in mouse models.
  • * Clinical findings reveal that patients with acute pancreatitis have lower levels of these beneficial bacteria in their feces, which correlates with more severe inflammation, highlighting potential targets for new treatments for SAP and similar inflammatory diseases.

Although increasing evidence has confirmed that the apoptosis of renal tubular epithelial cells (RTECs) is a crucial contributor to the onset and development of septic acute kidney injury (AKI), the pathological mechanism by which RTEC apoptosis is upregulated during septic AKI is not entirely clear. In this study, a rat model of septic AKI was induced by a cecal ligation puncture procedure or lipopolysaccharide (LPS) injection. Four differentially expressed long noncoding RNAs (DE-Lncs) in the rat model of septic AKI were determined using RNA-sequencing and verified by qRT-PCR.
