All parameters were associated with increased CRC risk at ROC analysis, but no relationship with clinical-pathological variables or survival outcomes was observed for glycemia, insulinemia or HOMA-IR. Conversely, advanced CRC stage(P = 0.018) was an independent predictor of increased Hb A1 c levels, which were also higher in patients who had disease progression compared with those who did not(P = 0.05). Elevated Hb A1 c levels showed a negative prognostic value both in terms of PFS(HR = 1.24) and OS(HR = 1.36) after adjustment for major confounders, which was further confirmed in a subgroup analysis performed after exclusion of diabetic patients.CONCLUSION HbA 1c might have a negative prognostic value in CRC, thus suggesting that glycemic metabolic markers should be carefully monitored in these patients, independently of overt diabetes.展开更多

But so far there are no published studies describing how single indispensable amino acids and different carbohydrate to lipid ratios influence those systems. Therefore, the present study aimed to evaluate whether arginine （Arg） intake and carbohydrate to lipid ratios would affect expression of GH, IGF-Ⅰ and INS in largemouth bass.展开更多

Patients were referred to the LMttS （Licking Memorial Health Systems） Outpatient Medication Therapy Insulin Clinic by their physician during the time periods of July 2012 through March 2013 and August 2014 through December 2014. Physician authorization permitted pharmacists to provide clinical monitoring in order to evaluate and adjust insulin, GLP-I agonist and amylin mimetic doses by adhering to approved dosing guidelines and policy and procedures. Hemoglobin Atc values were obtained from the patients electronic medical records. Patients achieved an average decrease in HbAlc of 0.8 percentage points over a mean of 83 days.
