Kruljac I., Ćaćić M., Ćaćić P., Ostojić V., Štefanović M., Šikić A., Vrkljan M. (2017) Diabetic ketosis during hyperglycemic crisis is associated with decreased all-cause mortality in patients with type 2 diabetes mellitus. Endocrine Patients with DK had a lower incidence of symptomatic heart failure and had improved renal function. They used less furosemide and antihypertensive drugs, more metformin and lower insulin doses, all of which was independently associated with decreased mortality. Plasma glucose and glycated hemoglobin levels were similar in both groups.
Conclusions:Patients with hyperglycemic crisis and DK have decreased all-cause mortality when compared to those with NKH. DK might be a compensatory mechanism rather than a complication in patients with hyperglycemic crises, but further prospective studies are warranted.
Infection, use of furosemide and benzodiazepines may be important precipitating factors of HHS. Prospective clinical trials are mandatory to analyze the safety of ACE-inhibitors and benzodiazepines in elderly patients with diabetes.
Gastric cancer is related to high mortality rates and advanced disease stage at the time of diagnosis. Its carcinogenesis is extensively studied and is associated with genetic and epigenetic changes, changed the interaction between tumor and adjacent stromal cells, and changes in the microenvironment molecule status. NEDD9 affects different signaling proteins and pathways, apoptosis, adhesion, cell migration, and invasiveness. Connexin-43 also assists in intercellular communications and has several channel-independent functions. Aberrant expression of those two gap junction proteins plays an essential role in metastatic processes. Our scope was to detect the expression of connexin-43 and NEDD9 in epithelial and stromal gastric cancer compartments and its relation to tumor progression and lymph node metastases. Cancer tissue from 53 cases of node-negative and 55 cases of node-positive primary gastric carcinoma patients was analyzed for connexin-43 and NEDD9 expression by immunohistochemical assay, and the results were correlated with the remaining clinical and pathological findings and survival. In our cohort of patients with lymph node metastases, we detected higher expression of epithelial connexin-43 in the primary tumor and stromal connexin-43 expression correlated with both epithelial NEDD9 (rho=0.453) and stromal NEDD9 (rho=0.484). Higher epithelial connexin-43 and NEDD9 expression were associated with higher mortality (HR 1.54, 95% CI 1.01 -2.37, p=0.048). Epithelial connexin-43 expression, both epithelial and stromal NEDD9 expression, T and N status were all independently associated with shorter survival. In summary, our findings suggest that increased expression of both epithelial and stromal NEDD9 and epithelial connexin-43 could potentially be used as prognostic gastric cancer biomarkers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
