Continuous Subcutaneous Insulin Infusion in Patients With Type 2 Diabetes A Cohort Study to Establish the Relationship Between Glucose Control and Plasma Oxidized Low Density Lipoprotein
Background: Oxidative stress is a detrimental feature of diabetes implicated in the progression of the disease and its complications. The relationship between insulin therapy and oxidative stress is complex. This study tested the hypothesis that improved glucose control, rather than insulin dose, is central to reduced oxidative stress in patients with type 2 diabetes following continuous subcutaneous insulin infusion (CSII). Methods: In this 16-week, multicenter study, 54 CSII-naïve patients with type 2 diabetes (age 57 ± 10 years, HbA1c 69 ± 15 mmol/mol [8.5 ± 1.4%], diabetes duration 13 ± 6 years) treated with either oral antidiabetic agents (OAD) alone (n = 17), basal insulin ± OAD (n = 17), or multiple daily injections (MDI) ± OAD (n = 20) were the evaluable group. Diabetes medications except metformin were discontinued, and 16 weeks of CSII was initiated. Insulin dose was titrated to achieve optimal glycemic control. A plasma marker of oxidative stress relevant to cardiovascular disease (oxidized low density lipoprotein [ox-LDL]) was assessed at baseline and week 16. Results: CSII improved glycemic control (HbA1c −13 ± 2 mmol/mol [−1.2 ± 0.2%]; fasting glucose −36.6 ± 8.4 mg/dL; mean glucose excursion −23.2 ± 6.5 mg/dL, mean ± SE; all P .05), but was significantly more pronounced in patients on statins (P = .019). The effect of CSII was more closely correlated to improvements in glucose excursion (P = .013) than to insulin dose (P > .05) or reduction in HbA1c (P > .05). Conclusions: CSII induces depression of plasma ox-LDL associated with change in glucose control, rather than with change in insulin dose. The effect is augmented in patients receiving statins
Effects of Once-Weekly Exenatide on Cardiovascular Outcomes in Type 2 Diabetes.
Abstract
BACKGROUND:
The cardiovascular effects of adding once-weekly treatment with exenatide to usual care in patients with type 2 diabetes are unknown.
METHODS:
We randomly assigned patients with type 2 diabetes, with or without previous cardiovascular disease, to receive subcutaneous injections of extended-release exenatide at a dose of 2 mg or matching placebo once weekly. The primary composite outcome was the first occurrence of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke. The coprimary hypotheses were that exenatide, administered once weekly, would be noninferior to placebo with respect to safety and superior to placebo with respect to efficacy.
RESULTS:
In all, 14,752 patients (of whom 10,782 [73.1%] had previous cardiovascular disease) were followed for a median of 3.2 years (interquartile range, 2.2 to 4.4). A primary composite outcome event occurred in 839 of 7356 patients (11.4%; 3.7 events per 100 person-years) in the exenatide group and in 905 of 7396 patients (12.2%; 4.0 events per 100 person-years) in the placebo group (hazard ratio, 0.91; 95% confidence interval [CI], 0.83 to 1.00), with the intention-to-treat analysis indicating that exenatide, administered once weekly, was noninferior to placebo with respect to safety (P<0.001 for noninferiority) but was not superior to placebo with respect to efficacy (P=0.06 for superiority). The rates of death from cardiovascular causes, fatal or nonfatal myocardial infarction, fatal or nonfatal stroke, hospitalization for heart failure, and hospitalization for acute coronary syndrome, and the incidence of acute pancreatitis, pancreatic cancer, medullary thyroid carcinoma, and serious adverse events did not differ significantly between the two groups.
CONCLUSIONS:
Among patients with type 2 diabetes with or without previous cardiovascular disease, the incidence of major adverse cardiovascular events did not differ significantly between patients who received exenatide and those who received placebo.

The Relationship Between Colonization, Secretor Status and Invitro Adhesion of Candida-Albicans to Buccal Epithelial-Cells From Diabetics
This study investigated whether oral candida infection in diabetics and adhesion of Candida albicans to buccal epithelial cells in vitro were related. Buccal cells from 50 patients with diabetes mellitus showed a significant increase in adhesion of C. albicans strain CDS 88 compared with those collected from 50 non-diabetic controls matched for age, sex and denture status. Oral candida carriage, candida infection and secretor status were also investigated in both groups. The frequency of carriage was increased, but not significantly, and there was a significantly higher incidence of candida infection in diabetic patients compared with controls. Diabetic patients who were non-secretors had a significantly increased frequency of oral candida carriage.link_to_subscribed_fulltex

Review: Nutritional support for patients with cirrhosis
Nutritional support is indicated when cirrhotic patients undergo surgery because they are malnourished, hypercatabolic and immunocompromised. However, the choice of nutrient may be problematic as the liver itself is the central organ of protein, fat and glucose metabolism. Branched chain amino acid- enriched solution may be the choice of protein source, as it is anticatabolic and it stimulates liver regeneration. Excessive glucose is undesirable as it may suppress endogenous fat utilization, which may be the preferred pathway of metabolism after hepatectomy. Medium chain triglycerides are preferred to long chain triglycerides as they are readily utilized and are not deposited in the liver; however, the tendency of cirrhotic patients to accumulate free fatty acids and glycerol after infusion of triglycerides dictates their use intermittently. Clinical studies have shown that perioperative nutritional support is beneficial in cirrhotic patients undergoing major hepatectomy or liver transplantation. The judicious choice of nutrient, care of the catheter and a limitation of the fluid infused are all prerequisites for the efficient use of perioperative nutritional support, which is complementary to a technically perfect operation.link_to_subscribed_fulltex
