The pathogenesis of diabetic kidney disease is a complex process caused by both glucotoxicity and lipotoxicity due to lipid accumulation. In cases of diabetic animals, lipid deposition is found in both tubular and glomerular portions of the kidneys, which are the major sites of diabetic nephropathy lesions. ⋯ The induction of oxidative stress, inflammation, fibrosis and apoptosis caused by lipid accumulation and lipid metabolites is called lipotoxicity. Renal lipotoxicity due to derangement in lipid metabolism may be a pathogenic mechanism leading to diabetic nephropathy and renal dysfunction.

Comparative Study Clinical Trial
Effect of Using the Rapid Shallow Breathing Index as Readiness Criterion for Spontaneous Breathing Trials in a Weaning Protocol.
This study aimed to compare the effect of using versus not using the Rapid-Shallow Breathing Index (RSBI) as a readiness criterion for Spontaneous Breathing Trials (SBT) on SBT success. ⋯ The inclusion of the RSBI in a readiness screen may not be useful in a weaning protocol.

The Prognostic Value of Endotoxemia and Intestinal Barrier Biomarker ZO-1 in Bacteremic Sepsis.
Intestinal barrier dysfunction exerts a pivotal pathophysiological role in the development of multiple organ dysfunction in sepsis. The present study was undertaken to investigate the potential role of serum intestinal fatty acid-binding protein (I-FABP) and zonula occludens-1 (ZO-1) levels as biomarkers of intestinal barrier dysfunction in bacteremic sepsis. ⋯ The results of this study indicate that serum ZO-1 might be a reliable biomarker of gut barrier dysfunction in sepsis, not affected by the abdominal or extra-abdominal site of infection. ZO-1, measured early at sepsis diagnosis, might represent a valuable additional prognostic tool for patients' outcome.

Prevailing hospital practice dictates a protracted phase of observation for patients with chest pain to establish or exclude the diagnosis of myocardial infarction. Early diagnosis of acute myocardial infarction may improve patient care and reduce both complications and hospital costs. A study was performed to investigate the feasibility of early diagnosis of myocardial infarction within the first 9 hours of the hospital stay. ⋯ Standard CK-MB mass measurements within 9 hours of arrival provided an accurate clinical assessment in > 99% of the cases. The high sensitivity and negative predictive values suggest that early diagnosis of myocardial infarction is feasible and reliable.

The poor outcomes in epithelial ovarian cancer necessitate new treatments. In this work, we systematically analyzed the inhibitory effects of ivermectin and the molecular mechanism of its action in ovarian cancer. ⋯ Our work suggests that ivermectin may be a useful addition to the treatment armamentarium for ovarian cancer and that targeting Akt/mTOR signaling is a therapeutic strategy to increase chemosensitivity in ovarian cancer.
