Pattern of soluble CD5 and CD6 lymphocyte receptors in critically ill patients with septic syndromes.
Soluble forms of CD5 and CD6 lymphocyte surface receptors (sCD5 and sCD6) are molecules that seem to prevent experimental sepsis when exogenously administered. The aim of this study was to assess sCD5 and sCD6 levels in patients with septic syndromes. ⋯ Levels of sCD5 and sCD6 in critically ill patients with systemic inflammatory response syndrome present a high variation and an elevated proportion of undetectability. Levels of sCD6 are associated with an increased risk of mortality in these patients.

Association of tumor necrosis factor α -308G/A and interleukin-6 -174G/C gene polymorphism with pneumonia-induced sepsis.
Sepsis is a lethal outcome of the inflammation and coagulation process. Human interleukin (IL)-6 and tumor necrosis factor (TNF) α are well-known inflammation factors closely associated with sepsis. In the present study, we aim to investigate the association of promoter-region polymorphisms IL-6 (-174G/C) rs1800795 and TNF-α (-308G/A) rs1800629 with pneumonia-induced sepsis. ⋯ In intensive care unit patients, the TNF-α -308A allele and the IL-6 rs1800795 allele variants were susceptibility risk factors for septic shock induced by pneumonia.

Preanesthetic mortality prediction in diabetics undergoing major lower limb amputation at a tertiary referral hospital: Implications of preoperative echocardiographic and laboratory values.
Cardiac comorbidities in patients undergoing amputation due to diabetic foot ulcer are associated with high mortality rates. The authors investigated whether preanesthetic echocardiographic and laboratory values can predict inhospital mortality in type II diabetes patients undergoing major lower limb amputation under spinal anesthesia. ⋯ Preoperative hemoglobin level and left ventricular ejection fraction are highly correlated with inhospital mortality in type II diabetes patients undergoing major lower extremity amputation under spinal anesthesia.

Mean arterial pressure and mean perfusion pressure deficit in septic acute kidney injury.
Changes in mean perfusion pressure (MPP) from premorbid resting values may contribute to the progression of septic acute kidney injury (AKI). ⋯ Mean arterial pressure and MPP deficits were substantial in septic shock patients, with patients with severe AKI having a greater MPP deficit. However, only CVP was independently associated with AKI progression. These findings suggest a possible role for venous congestion in septic AKI.

Risk factors for noninvasive ventilation failure in cancer patients in the intensive care unit: A retrospective cohort study.
The purpose of the study is to identify risk factors for noninvasive ventilation (NIV) failure in cancer patients with acute respiratory failure (ARF). ⋯ Noninvasive ventilation can avert ARF for most ICU cancer patients with ARF. For patients with pulmonary infections and high severity scores, NIV should be used with caution. Identifying risk factors for NIV failure using a comprehensive diagnostic approach and monitoring of NIV are paramount to improve outcomes.
