Sepsis, marked by hyperinflammation and subsequent immunosuppression, lacks effective phase-specific therapies. Although anisodamine hydrobromide (Ani HBr) reduced 28-day mortality in our prior trial, its mechanisms remained unclear. Here, we integrated network pharmacology, machine learning, immunological profiling, molecular simulations, and single-cell transcriptomics to elucidate Ani HBr's multi-target actions.

Background: Sepsis is an infection-induced systemic inflammatory response syndrome with high morbidity and mortality. β2-microglobulin (β2-MG), a low-molecular-weight protein involved in immune processes, shows potential for predicting the prognosis of various diseases. However, its role in sepsis prognosis remains unclear, necessitating further exploration.

Septic myocardial injury, a severe sepsis complication linked to high morbidity and mortality, remains a major global clinical challenge. Interleukin-33 (IL-33), a damage-associated pro-inflammatory factor, has been implicated in regulating immune responses and inflammation, but its specific role in septic myocardial injury has not been fully elucidated. This study examined IL-33's role in septic myocardial injury using Gene Expression Omnibus (GEO) database datasets, alongside in vitro and in vivo experiments.

Background: Community-acquired pneumonia (CAP) poses a significant health threat to the elderly population, leading to high morbidity and mortality rates. Serum ferritin, a critical indicator of iron metabolism, plays a pivotal role in inflammation and immune regulation. Nevertheless, its specific prognostic relevance in elderly patients with CAP remains unclear.

Background: Acute kidney injury (AKI) is a common complication in heart failure (HF) patients. Patients with heart failure who experience renal injury tend to have a poor prognosis. The objective of this study is to examine the correlation between the occurrence of AKI in heart failure patients and different mean arterial pressure (MAP) trajectories, with the goal of improving early identification and intervention for AKI.

Article Synopsis
  • The study examines how different Vitamin D administration methods affect the outcomes of COVID-19 patients, focusing on mortality, ICU admissions, hospital stays, and intubation rates.
  • A total of 21 studies with 4,553 participants were analyzed, revealing that Vitamin D supplementation significantly reduced mortality rates, especially with continuous dosing and lower total doses (less than 100,000 IU).
  • In patients with Vitamin D deficiency, mortality rates were notably lower with supplementation, while ICU admissions also decreased significantly with continuous dosing, indicating a potential benefit of Vitamin D in treating COVID-19.

  • Fibroblast growth factors (FGFs) are important proteins that influence cell development and metabolism, and their role in ovarian cancer (OC) is not well defined yet.
  • * In the study, researchers analyzed various data (transcriptional, survival, genetic variation) to understand FGFs' impact on OC patients and found that certain FGFs had differing expression levels in OC tissues compared to normal tissues.
  • * The results indicated that FGF expression is linked to tumor stages and clinical prognosis, suggesting FGFs could serve as potential prognostic biomarkers for OC patients.

  • Sepsis patients with type 2 diabetes mellitus (T2DM) often have longer recovery times and worse outcomes, prompting research to find related genes and improve predictive models.
  • The study utilized protein-protein interaction networks and machine learning to identify candidate genes, ultimately pinpointing three key genes (MMP8, CD177, and S100A12) with strong predictive potential for sepsis in T2DM.
  • These biomarkers were validated through lab techniques and demonstrated significant differences in expression patterns between healthy individuals and those with sepsis, offering new insights for diagnosis and treatment strategies for sepsis in T2DM patients.

Background: Sepsis significantly impacts morbidity and mortality, particularly among older adults. Despite extensive research, early recognition and prognosis prediction of sepsis remain challenging. IL-8, a chemokine produced by inflammatory cells like monocytes and endothelial cells, has shown potential in predicting mortality in sepsis patients, though its role in elderly sepsis remains unexplored.

  • Host immunity, influenced by vaccination and prior infections, plays a key role in how SARS-CoV-2 spreads, with a study analyzing the interactions between the virus's mutations and immune responses in vaccinated humans and mice.
  • A new model called the Prevalence Score (P-Score) outperforms previous methods in predicting how new variants could spread in vaccinated groups, emphasizing the importance of vaccine type and timing.
  • The results suggest that combining a wild-type inactivated vaccine with an Omicron mRNA vaccine could offer broader protection against various strains, though specific variants like EG.5.1 still present challenges, informing future vaccine strategies and public health planning.

Neuroinflammation and oxidative stress contribute to the progression of sepsis-associated encephalopathy (SAE). Angiotensin-converting enzyme 2 (ACE2) is considered to be a neuroprotective factor due to its anti-inflammatory and antioxidant properties. However, the role of ACE2 on myeloid cells in regulating SAE and the underlying mechanism warrants further exploration.

Article Synopsis
  • Sepsis can cause acute liver injury (ALI) in ICU patients, and the role of the enzyme ACE2 in this condition is not well understood.
  • A study found that ACE2 levels drop significantly in a mouse model of sepsis, and using ACE2-transgenic mice improved liver function and reduced cell death and inflammation compared to ACE2-knockout mice.
  • The research suggests that ACE2 protects against sepsis-induced ALI through a specific receptor pathway, indicating that enhancing ACE2 activity could be a potential treatment strategy for this condition.
