Purpose: This study assesses the behavior of serial blood lactate measurements during intensive care unit (ICU) stay to identify prognostic factors of unfavorable neurological outcomes (UO) in patients with aneurysmal subarachnoid hemorrhage (SAH).
Methods: We retrospectively reviewed all patients who were consecutively hospitalized with SAH between 2009 and 2016. Arterial blood lactate levels were routinely obtained on admission and every 6h in the ICU. Univariate/multivariate analyses were performed to identify independent predictors of UO (modified Rankin scale of 3-6 upon hospital discharge).
Results: There were 145 patients with 46% of UO. Initially, increased lactate levels reached maximum levels during the first 24h and then decreased to within the normal range. Then, the levels slightly increased again to within the normal range for the next 24h, especially in UO. On multiple regression analysis, lactate levels measured at 24h, and 48h after admission were strong predictors of UO. Lactate level measured at 48h after admission demonstrated the greatest accuracy and the highest specificity (area under the curve, 0.716; sensitivity, 40%; specificity, 92.1%).
Conclusions: The lactate level at 48h after admission was the most accurate predictor of UO with a high specificity in SAH patients.

The quality of biological samples used in metabolomics research is significantly influenced by preanalytical factors, such as the timing of centrifugation and freezing. This study aimed to evaluate how preanalytical factors, like delays in centrifugation and freezing, affect metabolomics research. Blood samples, collected in various tube types, were subjected to controlled pre- and postcentrifugation delays.

Objective: The mortality risk for critically ill patients in the intensive care unit (ICU) can be predicted through clinical assessments and laboratory test results. The accurate utilization of these parameters is essential for timely intervention and the initiation of appropriate therapeutic strategies. This study aims to retrospectively examine the relationship between patients' clinical status at ICU admission, prognostic risk scoring systems, biochemical and hematological parameters, and mortality outcomes.

The Warburg effect, characterized by the shift toward aerobic glycolysis, is closely associated with the onset and advancement of tumors, including multiple myeloma (MM). Nevertheless, the specific regulatory mechanisms of glycolysis in MM and its functional role remain unclear. In this study, we identified that growth differentiation factor 15 (GDF15) is a glycolytic regulator, and GDF15 is highly expressed in MM cells and patient samples.

Monitoring perioperative tissue perfusion is crucial in clinical anesthesia to protect organs and ensure patient safety. Indicators like hemodynamic parameters, tissue metabolism, and microcirculation markers are used for assessment. Studies show intraoperative hypotension negatively impacts outcomes, though blood pressure alone may not reflect tissue perfusion accurately.
