We explored the diagnostic value of a urine soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) for early sepsis identification, severity and prognosis assessment, and for secondary acute kidney injury (AKI). We compared this with white blood cell (WBC) counts, serum C-reactive protein (CRP), serum procalcitonin (PCT), urine output, creatinine clearance (CCr), serum creatinine (SCr), and blood urea nitrogen (BUN). ⋯ Besides being non-invasive, urine sTREM-1 testing is more sensitive than testing WBC, serum CRP, and serum PCT for the early diagnosis of sepsis, as well as for dynamic assessments of severity and prognosis. It can also provide an early warning of possible secondary AKI in sepsis patients.

Expanding the criteria for deceased organ donors increases the risk of delayed graft function (DGF) and complicates kidney transplant outcome. We studied whether donor neutrophil gelatinase-associated lipocalin (NGAL), a novel biomarker for acute kidney injury, could predict DGF after transplantation. ⋯ This first report on S-NGAL and U-NGAL levels in deceased donors shows that donor U-NGAL, but not donor S-NGAL, measurements give added value when evaluating the suitability of a potential deceased kidney donor.

Anemia is a frequently encountered problem during inflammation. Hepcidin is an interleukin-6 (IL-6)-induced key modulator of inflammation-associated anemia. Human sepsis is a prototypical inflammatory syndrome, often complicated by the development of anemia. However, the association between inflammation, hepcidin release and anemia has not been demonstrated in this group of patients. Therefore, we explored the association between hepcidin and sepsis-associated anemia. ⋯ These data suggest that hepcidin-25 may be an important modulator of anemia in septic patients with systemic inflammation.

Comparative Study
Women receive more trials of noninvasive ventilation for acute respiratory failure than men: a nationwide population-based study.
Previous studies in western countries have observed that women are less likely than men to receive intensive care and mechanical ventilation (MV). We aimed to investigate whether the gender difference also exists in Asian populations and in the provision of different types of MV including invasive (INV) and noninvasive ventilation (NIV). ⋯ Gender differences existed not only in the provision but also in the types of MV. Further studies are needed to understand why gender differences occur.

Ischemia/reperfusion after cardiopulmonary resuscitation (CPR) induces systemic inflammatory response and activation of endothelium and coagulation, resulting in a post-cardiac arrest syndrome. We analysed circulating (annexin V+) microparticles and their conjugates in resuscitated patients. ⋯ Resuscitated patients show substantially increased levels of different (annexin V+) microparticles and their conjugates immediately and 24 hours after cardiopulmonary resuscitation, suggesting an early onset of inflammation, an ongoing endothelial activation and a procoagulatory state. Additionally, microparticles of CPR patients may contribute to endothelial apoptosis. These results point to an involvement of microparticles in the development of the post-cardiac arrest syndrome.
