Sepsis progression is marked by a complex immune response, where the involvement of hypoxia-inducible factors (HIF) plays an uncertain role. The study aims to elucidate the involvement of HIF-1α in monocyte function during sepsis and its potential as a prognostic indicator. ⋯ HIF in monocytes acts as a suppressor of immune-inflammatory responses and antigen presentation, and may serve as a negative molecular marker for sepsis development.

Observational Study
Renin and angiotensin (1-7) offer predictive value in pediatric sepsis: findings from prospective observational cohorts.
Background: Pediatric sepsis is a common and complex syndrome characterized by a dysregulated immune response to infection. Aberrations in the renin-angiotensin system (RAS) are factors in several infections of adults. However, the precise impact of RAS dysregulation in pediatric sepsis remains unclear. ⋯ Nonsurvivors had higher levels of renin (8,207 ± 7,903) compared to survivors (2,433 ± 3,193) ( P = 0.0001) and lower levels of angiotensin (1-7) (60.9 ± 51.1) compared to survivors (104.0 ± 85.1) ( P < 0.05). A combination of renin, angiotensin (1-7) and procalcitonin achieved a model for diagnosis with an area under the receiver operating curve of 0.87 (95% CI: 0.81-0.92). Conclusion: Circulating renin and angiotensin (1-7) have predictive value in pediatric sepsis.

The purpose of this review is to investigate the long-term outcomes of cancer patients who experience sepsis or septic shock. ⋯ As cancer is becoming a chronic disease, there is an urgent need for studies on the quality of life of cancer patients who have experienced sepsis. The relationship between sepsis and cancer extends beyond its impact on the progression of cancer, as sepsis might also contribute to the development of cancer.

Septic cardiomyopathy is a common complication in patients with sepsis, and is one of the indicators of poor prognosis. Its pathogenesis is complex, involving calcium ion imbalance in cardiomyocytes, nitric oxide (NO) synthesis disorder, mitochondrial abnormalities and immune inflammatory reaction, especially mitochondrial abnormalities. In this paper, the mechanism of mitochondrial abnormalities causing septic cardiomyopathy was discussed from the aspects of mitochondrial structure change, mitochondrial energy metabolism disorder, redox imbalance, mitochondrial calcium overload, mitochondrial biosynthesis and autophagy abnormalities.

Background: Despite rapid advances in treatment, sepsis currently remains a major public health challenge worldwide. Over the past several years, there has been an increase in the clinical incidence of sepsis, as well as an increase in hospitalization rates, which bear the majority of the economic burden associated with sepsis. Sepsis is a public health burden due to the high fatality rates and accompanying morbidity. ⋯ Numerous pathogenic floras, including Escherichia coli , Staphylococcus aureus , Streptococcal , Enterococcus , and Pseudomonas , had greater rates among sepsis-related contacts with AKI. Furthermore, compared to hospitalization without comorbid AKI, the median total hospital charges and length of stay days for sepsis hospitalization with comorbid AKI were greater. Conclusion: With time, patients with sepsis have a higher frequency of AKI and a corresponding decline in mortality.
