Prevalence and risk factors for vaginal Candida colonization in women with type 1 and type 2 diabetes
BACKGROUND: Diabetes mellitus increases the rate of vaginal colonization and infection with Candida species METHODS: We surveyed women with diabetes receiving care at either an urban or suburban diabetes clinic to examine the relationship between vaginal Candida colonization, diabetes type and duration, and HbA(1c) level. 101 participants completed the self-administered questionnaire and self-collected a vaginal swab for Candida culture. Candida colonization was similar by age and race. RESULTS: Type 1 diabetics were three times as likely as type 2 diabetics to be colonized with any Candida species (OR = 3.4; 95% CI: 1.03, 11.41; p = 0.04); even after adjusting for abnormal HbA(1c), which had an independent effect (OR = 1.4; 95% CI: 1.04, 1.76; p = 0.02). Recent antibiotic use (OR = 4.5; 95% CI: 1.18, 16.79; p = 0.03), lifetime history of chlamydia (OR = 5.8; 95% CI: 1.09, 30.54; p = 0.04), and performing oral sex during the past 2 weeks (OR = 4.9; 95% CI:0.84, 28.27; p = 0.08) were also associated with Candida carriage after adjusting for diabetic type and abnormal HbA(1c). C. albicans was isolated from the majority of colonized type 1 participants (56%), while C. glabrata was the most common isolate among colonized type 2 participants (54%). CONCLUSIONS: Improving glucose control and possibly modifying sexual behavior may reduce risk of Candida colonization, and potentially symptomatic infection, among women with diabetes
Glargine and degludec: solution behaviour of higher dose synthetic insulins
Single, double and triple doses of the synthetic insulins glargine and degludec currently used in patient therapy are characterised using macromolecular hydrodynamic techniques (dynamic light scattering and analytical ultracentrifugation) in an attempt to provide the basis for improved personalised insulin profiling in patients with diabetes. Using dynamic light scattering and sedimentation velocity in the analytical ultracentrifuge glargine was shown to be primarily dimeric under solvent conditions used in current formulations whereas degludec behaved as a dihexamer with evidence of further association of the hexamers (âmulti-hexamerisationâ). Further analysis by sedimentation equilibrium showed that degludec exhibited reversible interaction between mono- and-di-hexamer forms. Unlike glargine, degludec showed strong thermodynamic non-ideality, but this was suppressed by the addition of salt. With such large injectable doses of synthetic insulins remaining in the physiological system for extended periods of time, in some case 24â40âhours, double and triple dose insulins may impact adversely on personalised insulin profiling in patients with diabetes

Rate of Hypoglycemia in Insulin-Treated Patients with Type 2 Diabetes Can Be Predicted from Glycemic Variability Data
Background: We set out to study the relationship between different measures of glycemic variability and the rate of hypoglycemia in patients with type 2 diabetes. Subjects and Methods: Data were pooled from three 24-week insulin trials including patients on twice-daily (BID) insulin lispro mix 75/25 (75% insulin lispro protamine suspension, 25% insulin lispro) (n = 805), daily (QD) insulin glargine (n = 1,019), insulin lispro protamine suspension (n = 353) (QD or BID), and insulin detemir (n = 166) (QD or BID), all with continuation of prestudy oral antihyperglycemic medications. Glycemic variability measures were derived from seven-point self-monitored blood glucose profiles. Results: At baseline, mean (+/- SD) age was 56.9 +/- 9.7 years, duration of type 2 diabetes was 9.5 +/- 6.1 years, hemoglobin A1c (HbA1c) was 8.9 +/- 1.1%, and 51.9% were male. Intra-day glucose coefficient of variation (CV), fasting blood glucose, intra-day minimum glucose and inter-day glucose CV at 24 weeks, and intra-day glucose CV at baseline were significantly correlated with the rate of hypoglycemia events between Weeks 12 to 24 (P <0.05 for all measures). Conclusions: Intra-day and inter-day glycemic variability is significantly associated with the risk of hypoglycemia in insulin-treated patients with type 2 diabetes, even after adjusting for mean glucose and HbA1c. The intra-day glycemic variability before starting insulin is significantly associated with the risk of hypoglycemia during insulin treatment, which points at treatment-and patient-related factors mediating this relationshi

A comparison of lipid and glycemic effects of pioglitazone and rosiglitazone in patients with type 2 diabetes and dyslipidemia
Published reports suggest that pioglitazone and rosiglitazone have different effects on lipids in patients with type 2 diabetes. However, these previous studies were either retrospective chart reviews or clinical trials not rigorously controlled for concomitant glucose- and lipid-lowering therapies. This study examines the lipid and glycemic effects of pioglitazone and rosiglitazone.
We enrolled subjects with a diagnosis of type 2 diabetes (treated with diet alone or oral monotherapy) and dyslipidemia (not treated with any lipid-lowering agents). After a 4-week placebo washout period, subjects randomly assigned to the pioglitazone arm (n = 400) were treated with 30 mg once daily for 12 weeks followed by 45 mg once daily for an additional 12 weeks, whereas subjects randomly assigned to rosiglitazone (n = 402) were treated with 4 mg once daily followed by 4 mg twice daily for the same intervals.
Triglyceride levels were reduced by 51.9 +/- 7.8 mg/dl with pioglitazone, but were increased by 13.1 +/- 7.8 mg/dl with rosiglitazone (P < 0.001 between treatments). Additionally, the increase in HDL cholesterol was greater (5.2 +/- 0.5 vs. 2.4 +/- 0.5 mg/dl; P < 0.001) and the increase in LDL cholesterol was less (12.3 +/- 1.6 vs. 21.3 +/- 1.6 mg/dl; P < 0.001) for pioglitazone compared with rosiglitazone, respectively. LDL particle concentration was reduced with pioglitazone and increased with rosiglitazone (P < 0.001). LDL particle size increased more with pioglitazone (P = 0.005).
Pioglitazone and rosiglitazone have significantly different effects on plasma lipids independent of glycemic control or concomitant lipid-lowering or other antihyperglycemic therapy. Pioglitazone compared with rosiglitazone is associated with significant improvements in triglycerides, HDL cholesterol, LDL particle concentration, and LDL particle size
Utilization of Glucose Oxidase for Extending the ShelfâLife of Fish
The preservative benefits of the enzymic glucose oxidase/catalase system were measured in refrigerated, fresh, whole winter flounder (Pseudopleuronectes americanus Waldbaum) and winter flounder fillets. The enzyme system was applied as a dip, as an ice and immobilized in algin blankets. Advantages were an extended period of sensory acceptance and delayed onset of putrefactive odors, 21 days vs 15 days for controls. The pattern of endogenous hypoxanthine accumulation and decline was unaffected, but parameters thought to measure proteolytic activity were modified: creatinine turnover was slowed and ammonia generation was retarded.
