Assessment of factors that determine the mean absolute relative difference in flash glucose monitoring with reference to plasma glucose levels in Japanese subjects without diabetes.

The Abbott FreeStyle Libre flash glucose monitoring system (FGM) is a recently introduced, but widespread continuous glucose monitoring system. While its mean absolute relative difference (MARD) value indicating its accuracy is acceptable with reference to the self-monitoring of blood glucose (SMBG) levels, few reports have examined the MARD in sensor glucose values of FGM (FGM-SG) with reference to plasma glucose (PG) levels and the factors determining it. We performed oral glucose tolerance tests (OGTTs) in 25 Japanese subjects without diabetes.

Evaluation of the relationship between glycated hemoglobin A1c and mean glucose levels derived from the professional continuous flash glucose monitoring system.

Previously, we reported that short-term continuous glucose monitoring (CGM) with the professional iPro2 CGM device is a good clinical indicator of glycated hemoglobin (HbA1c) levels. However, there was no significant correlation between CGM and HbA1c levels when HbA1c levels were >8.0%.

Dapagliflozin rescues endoplasmic reticulum stress-mediated cell death.

The new type 2 diabetes drug, dapagliflozin, reduces blood glucose levels and body weight by inhibiting sodium glucose transporter 2 (SGLT2) in proximal tubular cells. SGLT2 inhibitors might modulate glucose influx into renal tubular cells, thereby regulating the metabolic conditions that cause endoplasmic reticulum (ER) stress in the cells. In this study, we examined the effect of dapagliflozin on ER stress in the HK-2 proximal tubular cell line and in the kidney of db/db mice to characterise its function in diabetic nephropathy (DN).

The Impact of Short-Term Professional Continuous Glucose Monitoring on Glycemic Control Via Lifestyle Improvement.

Background: The efficacy of short-term professional continuous glucose monitoring (CGM) for glycemic control in patients with diabetes remains unclear.

Methods: We performed a 3-month study to evaluate the benefits of CGM in 64 patients.

Results: The overall glycemic control of patients who underwent CGM improved significantly; however, that of patients maintaining the same medications did not improve overall.

Assessment of factors determining an HbA1c concentration ≤7.5% in patients with type 1 diabetes.

Background: Establishing an optimal insulin regimen is crucial for maintaining glycemic control in patients with type 1 diabetes (T1D). The aim of the present study was to determine the insulin dose required to achieve an HbA1c concentration ≤7.5% in Japanese patients with T1D.

Effect of carbohydrate counting using bolus calculators on glycemic control in type 1 diabetes patients during continuous subcutaneous insulin infusion.

The present study examined the long-term efficacy of insulin pump therapy for type 1 diabetes patients when carried out using carbohydrate counting with bolus calculators for 1 year. A total of 22 type 1 diabetes patients who had just started continuous subcutaneous insulin infusion were examined and divided into two groups: one that was educated about carbohydrate counting using bolus calculators (n = 14); and another that did not use bolus calculators (n = 8). After 1 year, the hemoglobin A1c levels of the patient group that used bolus calculators decreased persistently and significantly (P = 0.

HBA1C AND MEAN GLUCOSE DERIVED FROM SHORT-TERM CONTINUOUS GLUCOSE MONITORING ASSESSMENT DO NOT CORRELATE IN PATIENTS WITH HBA1C >8.

Objective: Optimum therapy for patients with diabetes depends on both acute and long-term changes in plasma glucose, generally assessed by glycated hemoglobin (HbA1c) levels. However, the correlation between HbA1c and circulating glucose has not been fully determined. Therefore, we carefully examined this correlation when glucose levels were assessed by continuous glucose monitoring (CGM).

Fyn phosphorylates AMPK to inhibit AMPK activity and AMP-dependent activation of autophagy.

We previously demonstrated that proto-oncogene Fyn decreased energy expenditure and increased metabolic phenotypes. Also Fyn decreased autophagy-mediated muscle mass by directly inhibiting LKB1 and stimulating STAT3 activities, respectively. AMPK, a downstream target of LKB1, was recently identified as a key molecule controlling autophagy.

APPL1 promotes glucose uptake in response to mechanical stretch via the PKCζ-non-muscle myosin IIa pathway in C2C12 myotubes.

Expression of adaptor protein, phosphotyrosine interaction, pleckstrin homology domain, and leucine zipper containing 1 (APPL1) promoted glucose transporter 4 (GLUT4) translocation and glucose uptake in adipose and muscle tissues in response to stimulation with insulin, adiponectin, or exercise. In response to mechanical stretch, knockdown of APPL1 in C2C12 myotubes suppressed glucose uptake. APPL1-induced increased glucose uptake was mediated by protein kinase C (PKC) ζ but not AKT, AMPK, or calmodulin-dependent protein kinase.

Effect of dapagliflozin on colon cancer cell [Rapid Communication].

Dapagliflozin is a SGLT2 (Sodium/Glucose cotransporter 2) inhibitor that reduces circulating glucose levels in type 2 diabetic patients by blocking the SGLT2-dependent reabsorption of glucose in the kidney. Dapagliflozin is metabolized by UGT1A9 (UDP Glucuronosyltransferase 1 family, Polypeptidase A9), suppressing its SGLT2 inhibitor activity. However little information is available on whether dapagliflozin acts in the absence of dapagliflozin metabolism.

Glycosuria medicated with ipragliflozin and nifedipine or ipragliflozin and candesartan: a case report.

Introduction: Animal studies have reported that treatment with angiotensin II receptor blockers reduced kidney sodium-dependent glucose cotransporter expression. We therefore hypothesized that patients with hypertension treated with an angiotensin II receptor blocker (candesartan) would probably have an increased response to sodium-dependent glucose cotransporter inhibitor therapy (ipragliflozin) compared with patients treated with alternative hypertensive medications such as calcium channel blockers (nifedipine). Although sodium-dependent glucose cotransporter inhibitor (ipragliflozin) is a new anti-diabetic medicine, the clinical efficacy in the Japanese population has not been fully evaluated.
