Regimen comprising GLP-1 receptor agonist and basal insulin can decrease the effect of food on glycemic variability compared to a pre-mixed insulin regimen.

BACKGROUND: Increasing evidence suggests that glucagon-like peptide 1 (GLP-1) receptor agonists (RA) can stabilize glycemic variability (GV) and interfere with eating behavior. This study compared the impact of insulin, GLP-1 RA, and dietary components on GV using professional continuous glucose monitoring (CGM). METHODS: Patients with type 2 diabetes underwent CGM before and after switching from a twice-daily pre-mixed insulin treatment regimen to a GLP-1 RA (liraglutide) plus basal insulin regimen. The dietary components were recorded and analyzed by a certified dietitian. The interactions between the medical regimen, GV indices, and nutrient components were analyzed. RESULTS: Sixteen patients with type 2 diabetes were enrolled in this study. No significant differences in the diet components and total calorie intake between the two regimens were found. Under the pre-mixed insulin regimen, for increase in carbohydrate intake ratio, mean amplitude of glucose excursion (MAGE) and standard deviation (SD) increased; in contrast, under the new regimen, for increase in fat intake ratio, MAGE and SD decreased, while when the protein intake ratio increased, the coefficient of variation (CV) decreased. The impact of the food intake ratio on GV indices disappeared under the GLP-1 RA regimen. After switching to the GLP-1 RA regimen, the median MAGE, SD, and CV values decreased significantly. However, the significant difference in GV between the two regimens decreased during the daytime. CONCLUSION: A GLP-1 RA plus basal insulin regimen can stabilize GV better than a regimen of twice-daily pre-mixed insulin, especially in the daytime, and can diminish the effect of food components on GV.

Ankle-Brachial Index Is Independently Associated With Cardiovascular Outcomes and Foot Ulcers in Asian Patients With Type 2 Diabetes Mellitus.

Background and Aims: The ankle-brachial index (ABI) is an efficient tool for objectively documenting the presence of lower-extremity peripheral arterial disease (PAD). The predictive factors of cardiovascular events and diabetic foot ulcer were not clear from the ABI examination in Taiwanese patients with type 2 diabetes mellitus (DM). Methods: We enrolled 482 patients with type 2 DM who regularly visited the outpatient department of Chang Gung Memorial Hospital and received ABI as well as brachial-ankle pulse wave velocity (ba-PWV) examinations from 2010 to 2017. Age, gender, PAD symptoms, comorbidities, family history of chronic diseases, lifestyle (smoking, alcohol consumption, and exercise), height, weight, waist circumference, monofilament testing and foot ulcer status were studied. Results: There were 104 (22%) patients (mean age, 67.8 years) with the ABI <1.0. These patients with low ABI (ABI<1.0) had a significantly older age (p=0.001), higher delta PWV (p<0.001), higher rates of stroke (p=0.007), myocardial infarction (p=0.016), and foot ulcer (p=0.039). In a multivariable analysis model, the adjusted odds ratio (aOR) for myocardial infarction, stroke, and foot ulcers associated with low ABI were 1.219 (0.397-3.743, p=0.729), 1.204 (0.556-2.610, p=0.638), and 2.712 (1.199-6.133, p=0.017), respectively. The patients with low PWV (PWV<1400 cm/s) were significantly younger (p<0.001) and had a lower rate of hypertension (p<0.001), and higher percentages of stroke (p=0.027) and dialysis (p=0.041) family history. Conclusions: Low ABI was associated with cardiovascular events and diabetic foot ulcer independently in patients with type 2 DM.

Evaluation of Disease Complications Among Adults With Type 1 Diabetes and a Family History of Type 2 Diabetes in Taiwan.

Importance: Patients with type 1 diabetes (T1D) and a family history of type 2 diabetes (T2D) appear to be at a high risk of diabetes complications and other cardiovascular diseases. However, estimates of individual risks in patients in Taiwan are largely unavailable or unreliable. Objective: To evaluate the risk of diabetes complications and major adverse cardiovascular events (MACEs) in patients with T1D with a family history of T2D. Design, Setting, and Participants: A population-based cohort study used the Taiwan National Health Insurance Research Database. Participants included all individuals registered in that database on December 31, 2017, and followed up since March 1, 1995. The data were analyzed from December 6, 2018, to December 5, 2019. Exposure: Patients with T1D and a family history of T2D were evaluated. Main Outcomes and Measures: The prevalence and hazard ratios (HRs) of diabetes complications and other cardiovascular diseases in patients with T1D were analyzed. The MACEs were identified by diagnostic or procedural codes and heritability was formulated by the registry data of beneficiaries. Results: Of 27 370 965 individuals included in the database, 11 237 (mean [SD] age, 22.7 [14.4] years; 54% were female) had T1D. The crude prevalence of T1D was 0.04%, with a female to male ratio of 1.22: 1. The adjusted HRs in individuals who had a first-degree relative with T2D were 2.61 (95% CI, 1.32-5.16) for MACEs at an age at diagnosis of less than 20 years. Adjusted HRs were 1.44 (95% CI, 1.27-1.64) for diabetic neuropathy, 1.28 (95% CI, 1.12-1.47) for retinopathy, and 1.24 (95% CI, 1.06-1.47) for neuropathy at all ages of diagnosis. Conclusions and Relevance: In this study of patients in Taiwan with T1D, having relatives with T2D was associated with an increase in the individual risks of developing diabetes complications. Patients with T1D and a family history of T2D might have more complications and require close management.

Renal and Glucose-Lowering Effects of Empagliflozin and Dapagliflozin in Different Chronic Kidney Disease Stages.

Objective: The objective of this study was to investigate the effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors on renal function in different stages of chronic kidney disease (CKD). Design and Methods: We conducted a retrospective cohort study using longitudinal claims data from May 2016-December 2017 from the Chang Gung Research Database. Patients who used one of the three types of SGLT2 inhibitor available at Chang Gung Memorial Hospital, namely empagliflozin 10 mg/tab (Empa10), empagliflozin 25 mg/tab (Empa25), and dapagliflozin 10 mg/tab (Dapa), were included, with the same number of matched non-users. Analysis of variance was used for continuous variables and the chi-square test was applied for categorical variables. Differences in data between two groups were analyzed using an independent t-test, and the basic data before and after treatment were analyzed using generalized estimating equation (GEE). The association among renal function changes was analyzed using a Cox proportional hazards model, with the results presented as unadjusted hazard ratios (HRs) with 95% confidence intervals (95% CIs). Results: Among the 7,624 SGLT2 inhibitor users, 1,696 patients used Empa10, 2,654 used Empa25, and 3,274 used Dapa. Compared with non-users, dapagliflozin had the lowest risk of estimated glomerular filtration rate (eGFR) decrease over 40% from baseline within 1 year (HR 0.36, 95% CI 0.25-0.51). By using the ICD-10-CM code N179, the acute kidney injury (AKI)-related hospitalization rate was lower in Empa10 and Dapa users than in non-users (HR 0.65, 95% CI 0.49-0.86). Conclusion: Lower risk of eGFR decrease over 40% and AKI-related hospitalization was found in all SGLT2 inhibitor users across the different CKD stages.

Impact of Carbohydrate on Glucose Variability in Patients with Type 1 Diabetes Assessed Through Professional Continuous Glucose Monitoring: A Retrospective Study.

INTRODUCTION: The aim of this study was to objectively analyze the correlation between dietary components and blood glucose variation by means of continuous glucose monitoring (CGM). METHODS: Patients with type 1 diabetes mellitus (T1DM) who received CGM to manage their blood glucose levels were enrolled into the study, and the components of their total caloric intake were analyzed. Glycemic variation parameters were calculated, and dietary components, including percentages of carbohydrate, protein and fat in the total dietary intake, were analyzed by a dietitian. The interaction between parameters of glycemic variability and dietary components was analyzed. RESULTS: Sixty-one patients with T1DM (33 females, 28 males) were enrolled. The mean age of the participants was 34.7 years, and the average duration of diabetes was 14 years. Glycated hemoglobin before CGM was 8.54%. Participants with a carbohydrate intake that accounted for < 50% of their total caloric intake had a longer DM duration and a higher protein and fat intake than did those with a carbohydrate intake that accounted for ≥ 50% of total caloric intake, but there was no between-group difference in total caloric intake per day. The group with a carbohydrate intake that accounted for < 50% of their total caloric intake also had lower nocturnal continuous overlapping net glycemic action (CONGA) 1, - 2 and - 4 values. The percentage of protein intake had a slightly negative correlation with mean amplitude of glycemic excursions (MAGE) (r = - 0.286, p < 0.05) and a moderately negative correlation with coefficient of variation (CV) (r = 0.289, p < 0.05). One additional percentage of protein calories of total calories per day decreased the MAGE to 4.25 mg/dL and CV to 0.012 (p < 0.05). The optimal dietary protein percentage for MAGE < 140 mg/dL was 15.13%. The performance of predictive models revealed the beneficial effect of adequate carbohydrate intake on glucose variation when combined with protein consumption. CONCLUSIONS: Adequate carbohydrate consumption-but not more than half the daily total calories-combined with protein calories that amount to approximately 15% of the daily caloric intake is important for glucose stability and beneficial for patients with T1DM.

The efficacy and safety of concentrated herbal extract granules, YH1, as an add-on medication in poorly controlled type 2 diabetes: A randomized, double-blind, placebo-controlled pilot trial.

BACKGROUND: In Asian countries, many patients with type 2 diabetes fail to achieve controlled glycated hemoglobin (HbA1c) levels while taking several classes of oral hypoglycemic agents (OHAs). Traditional Chinese medicine could be an alternative therapeutic option for poorly controlled type 2 diabetes. YH1 is a concentrated Chinese herbal extract formula that combines Rhizoma Coptidis and Shen-Ling-Bai-Zhu-San. This randomized, double-blind, placebo-controlled pilot study evaluated YH1 as an add-on medication for poorly controlled type 2 diabetes. METHODS: Forty-six patients with poorly controlled type 2 diabetes were randomly assigned 1:1 to the YH1 or placebo group. Before the trial, all subjects had received three or more classes of OHAs with HbA1c > 7.0% (53 mmol/mol) and a body mass index ≥ 23 kg/m2. During the 12-week trial, participants continued to take OHAs without any dose or medication changes. The primary endpoint was the percentage change in HbA1c level. Per-protocol analysis was applied to the final evaluation. RESULTS: At week 12, there was an 11.1% reduction in HbA1c from baseline and a 68.9% increase in homeostatic model assessment (HOMA) of ß cell function in the YH1 group, which also exhibited significant reductions in two-hour postprandial glucose (-26.2%), triglycerides (-29.5%), total cholesterol (-21.6%), low-density lipoprotein cholesterol (-17.4%), body weight (-0.5%), and waist circumference (-1.1%). The changes in fasting plasma glucose, HOMA insulin resistance and symptom scores were not significantly different between the YH1 and placebo groups. No serious adverse events occurred during this clinical trial. CONCLUSIONS: This pilot study indicates that YH1 together with OHAs can improve hypoglycemic action and ß-cell function in overweight/obese patients with poorly controlled type 2 diabetes. YH1 is a safe add-on medication for OHAs and has beneficial effects on weight control and lipid metabolism. A larger study population with longer treatment and follow-up periods is required for further verification.

Coadministration of DPP-4 inhibitor and insulin therapy does not further reduce the risk of cardiovascular events compared with DPP-4 inhibitor therapy in diabetic foot patients: a nationwide population-based study.

BACKGROUND: The effect of combined insulin and dipeptidyl peptidase-4 inhibitor (DPP4i) therapy on major adverse cardiovascular events (MACEs) in patients with diabetic foot is unclear. METHODS: We conducted this nationwide cohort study using longitudinal claims data obtained from the Taiwan National Health Insurance program and included 19,791 patients with diabetic foot from 2007 to 2014. Patients receiving DPP4i-based therapy and/or insulin-based therapy after a diagnosis of diabetic foot were categorized into combined, DPP4i- or insulin-based groups, respectively. The risk of MACEs including nonfatal myocardial infarction, nonfatal stroke, cardiac death, and heart failure was assessed using Cox proportional hazards analysis and propensity score matching. RESULTS: Among the 19,791 patients with diabetic foot (mean age, 58.8 years [SD, 12.5]; men, 51.2%), 6466 received DPP4i-based therapy, 1925 received insulin-based therapy, and 11,400 received combined DPP4i and insulin therapy. The DPP4i-based and insulin-based groups had a lower risk of MACEs (HR 0.53, 95% CI 0.50-0.57 DPP4i only; HR 0.89, 95% CI 0.81-0.97 insulin only) than the combined group. After propensity score matching, the incidence of all complications in the DPP4i-based group was still significantly lower than that in the combined group (HR 0.55, 95% CI 0.51-0.59 for MACEs; HR 0.32, 95% CI 0.24-0.42 for nonfatal myocardial infarction; HR 0.70, 95% CI 0.63-0.78 for nonfatal stroke; HR 0.22, 95% CI 0.13-0.38 for cardiac death; HR 0.22, 95% CI 0.19-0.25 for any death; HR 0.16, 95% CI 0.13-0.20 for amputation). In the diabetic foot patients with end-stage renal disease (ESRD), the benefit of a lower incidence of MACEs in the DPP4i-based group disappeared (HR 0.77, 95% CI 0.58-1.08). CONCLUSIONS: This study demonstrated that the patients with diabetic foot receiving DPP4i-based therapy had a lower risk of MACEs than those receiving combined therapy with DPP4i and insulin, but that the effect disappeared in those with concurrent ESRD.

Higher body weight and distant metastasis are associated with higher radiation exposure to the household environment from patients with thyroid cancer after radioactive iodine therapy.

There were insufficient data regarding radiation exposure to the household environment from patients with thyroid cancer who received radioactive iodine (RAI) therapy in Asia; we therefore performed the present study at the Chang Gung Memorial Hospital in Keelung, Taiwan.Patients with papillary or follicular thyroid cancer who received 3.7 GBq (100 mCi) RAI were enrolled in this prospective hospital-based study. The enrolled patients were asked to place a thermoluminescent dosimeter in the living room, bedroom, and bathroom of their houses for 4 weeks to measure radiation exposure to the household environment.A total of 43 patients (18 men and 25 women; mean age 51 ±â€Š13 years) who received 3.7 GBq (100 mCi) RAI completed the study. The mean value of total radiation exposure over 4 weeks from the patients to the bedroom, bathroom, and living room (eliminating the background radiation factor) was 0.446 ±â€Š0.304 (0.088-1.382) mSv. We divided the patients into 2 groups: those with more than and less than the mean value of total radiation exposure to the bedroom, bathroom, and living room. Factors associated with the higher amount of radiation exposure from the patients to the household environment were patient body weight (P = .025, univariate analysis; P = .037, multivariate analysis, odds ratio [95% confidence interval] 1.067 [1.004-1.134]) and distant metastases based on I post-therapy scanning (P = .041, univariate analysis; P = .058, multivariate analysis, odds ratio [95% confidence interval] 6.453 [0.938-44.369]); age, sex, body mass index, renal function, serum stimulated thyroglobulin level, and recombinant human thyroid-stimulating hormone use were not associated with the amount of radiation exposure from the patients to the household environment.Higher body weight and distant metastases may be the best predictors for higher radiation exposure to the household environment from patients with thyroid cancer after RAI therapy.

Glucose Variability and ß- Cell Response by GLP-1 Analogue added-on CSII for Patients with Poorly Controlled Type 2 Diabetes.

The effects of twice-daily GLP-1 analogue injections added on continuous subcutaneous insulin infusion (CSII) in patients with poorly controlled type 2 diabetes (T2DM) were unknown. After optimization of blood glucose in the first 3 days by CSII during hospitalization, patients with poorly controlled T2DM were randomized to receive CSII combined with injections of exenatide or placebo for another 3 days. A total of 51 patients (30 in exenatide and 21 in placebo groups) with mean A1C 11% were studied. There was no difference in mean glucose but a significant higher standard deviation of plasma glucose (SDPG) was found in the exenatide group (50.51 ± 2.43 vs. 41.49 ± 3.00 mg/dl, p = 0.027). The improvement of incremental area under the curve (AUC) of glucose and insulinogenic index (Insulin 0-peak/ Glucose 0-peak) in 75 g oral glucose tolerance test was prominent in the exenatide group (p < 0.01). The adiponectin level was significantly increased with exenatide added on (0.39 ± 0.32 vs. -1.62 ± 0.97 µg/mL, in exenatide and placebo groups, respectively, p = 0.045). In conclusion, the add-on of GLP-1 analogue to CSII increased glucose variability and the ß - cell response in patients with poorly controlled T2DM.

Polymorphisms of GLP-1 receptor gene and response to GLP-1 analogue in patients with poorly controlled type 2 diabetes.

AIM: The relationship between genetic polymorphisms of the glucagon-like peptide-1 (GLP-1) receptor (GLP1R) gene and unresponsiveness to GLP-1 analogue treatment in patients with poorly controlled type 2 diabetes mellitus (DM) is unclear. METHODS: Thirty-six patients with poorly controlled type 2 DM were enrolled and they received six days of continuous subcutaneous insulin infusion for this study. After the normalization of blood glucose in the first 3 days, the patients then received a combination therapy with injections of the GLP-1 analogue, exenatide, for another 3 days. All 13 exons and intron-exon boundaries of the GLP1R gene were amplified to investigate the association. RESULTS: The short tandem repeat at 8GA/7GA (rs5875654) had complete linkage disequilibrium (LD, with r2 = 1) with single nucleotide polymorphism (SNP) rs761386. Quantitative trait loci analysis of GLP1R gene variation with clinical response of GLP1 analogue showed the missense rs3765467 and rs761386 significantly associated with changes in the standard deviation of plasma glucose (SDPG(baseline) - SDPG(treatment with GLP-1 analogue)) (P = 0.041 and 0.019, resp.). The reported P values became insignificant after multiple testing adjustments. CONCLUSION: The variable response to the GLP-1 analogue was not statistically correlated with polymorphisms of the GLP1R gene in patients with poorly controlled type 2 DM.

Professional continuous glucose monitoring for the identification of type 1 diabetes mellitus among subjects with insulin therapy.

The identification of type 1 diabetes in diabetic subjects receiving insulin therapy is sometimes difficult. The purpose of this study is to evaluate whether results of professional continuous glucose monitoring can improve the identification of type 1 diabetes.From 2007 to 2012, 119 adults receiving at least twice-daily insulin therapy and professional continuous glucose monitoring were recruited. Type 1 diabetes was diagnosed by endocrinologists according to American Diabetes Association standards, including a very low C-peptide level (<0.35  pg/mL) or the presence of diabetic ketoacidosis. Continuous glucose monitoring was applied for 3 days.Among 119 subjects, 86 were diagnosed with type 1 diabetes. Subjects with type 1 diabetes were younger (33.8 vs 52.3 years old, P < 0.001), had lower body mass index (BMI, 21.95 vs 24.42, P = 0.003), lower serum creatinine (61.77  vs 84.65 µmol/L, P = 0.001), and higher estimated glomerular filtration rate (108.71 vs 76.48 mg/mL/min/1.73m2, P < 0.001) than subjects with type 2 diabetes. Predictive scores for identification of type 1 diabetes were constructed, including age, BMI, average mean amplitude of glucose excursion in days 2 and 3, and the area under the curve of nocturnal hyperglycemic and hypoglycemic states. The area under the receiver operating characteristic curve was 0.90. With the cutoff of 0.58, the sensitivity was 86.7% and the specificity was 80.8%. The good performance was validated by the leave-one-out method (sensitivity 83.3%, specificity 73.1%).Professional continuous glucose monitoring is a useful tool that improves identification of type 1 diabetes among diabetic patients receiving insulin therapy.

Association of body weight with the risk for malignancies in hospitalized patients with or without diabetes mellitus in Taiwan.

BACKGROUND: The purpose of this study was to determine the risk for cancers in patients with and without type 2 diabetes mellitus (DM) stratified by body mass index (BMI). METHODS: Patients hospitalized from January 2000 to December 2010 with a diagnosis of malignant neoplasm (International Classification of Diseases, Ninth Revision, codes 140-208.91) were included. Diabetes mellitus was defined as a fasting blood glucose of 126 mg/dL or greater or a postprandial blood glucose of 200 mg/dL or greater. The patients were categorized according to BMI criteria for Asians: normal weight, BMI of less than 24 kg/m; overweight, BMI of greater than 24 kg/m; and obese, BMI of greater than 27 kg/m. RESULTS: A total of 42,229 patients were included, of which 24,884 (59%) were normal weight, 10,096 (24%) were overweight, and 7,249 (17%) were obese. There were 4,195 (16.9%), 2,056 (20.4%), and 1,625 (22.4%) patients with DM in the normal weight, overweight, and obese groups, respectively. Regardless of weight, the diabetic patients were more likely to have pancreas, liver, urinary tract, prostate, skin, hematological, lung, secondary, and gastric malignancies but were less likely to have cervical, oropharyngeal, nasopharyngeal, breast, or thyroid cancer. Regardless of sex or the presence or the absence of DM, the patients with more than 1 malignancy were more likely to die than were those with only 1 malignancy. Furthermore, the obese diabetic patients had higher mortality than did the obese nondiabetic patients with the same number of cancers. CONCLUSIONS: Regardless of weight category (normal, overweight, or obese), diabetic patients are more likely to have pancreas, liver, urinary tract, prostate, skin, hematological, lung, secondary, and gastric malignancies. Diabetic patients may benefit from increased surveillance for these cancers.

Effect of growth hormone on dawn phenomenon in patients with type 2 diabetes.

We aimed to investigate the involvement of growth hormone in dawn phenomenon and insulin sensitivity in patients with type 2 diabetes mellitus (T2DM). On six occasions separated by intervals of at least 3 days, subjects received early evening (16:00 hours) or late night (23:00 hours) pretreatment with subcutaneous injection of normal saline, human growth hormone, or octreotide. Modified euglycemic insulin clamp test was done 16 hours later and variable glucose infusion (M values) was determined. Plasma glucose, serum insulin, insulin-like growth factor-1, non-esterified fatty acids, and metabolic clearance rate of insulin (MCRI) were measured. Early evening application of growth hormone decreased MCRI 16 hours later, suggesting reduction in insulin sensitivity. Exogenous growth hormone injection reduced insulin sensitivity in T2DM patients. Results provide direct evidence for the role of growth hormone in regulating the insulin sensitivity in insulin-resistant patients.

Inertia on hypoglycemia: highlight from a Taiwan subgroup analysis of Real-Life Effectiveness and Care Patterns of Diabetes Management (RECAP-DM) study.

Type 2 diabetes mellitus is a global health issue. Patients with poor glycemic control often suffer from cardiovascular, cerebrovascular, neuropathic, and nephropathic complications as well as other chronic conditions. Therapeutic guidelines recommend that diabetic patients should maintain their HbA(1c) level below a certain target in order to minimize the risk of developing complications. However, hypoglycemia is recognized as a major impediment to the adequate control of type 2 diabetes. Hypoglycemia can manifest symptoms of varying degrees of severity. Moreover, an association between hypoglycemia and cardiovascular morbidity and mortality has been reported. Here, we present a post hoc Taiwan subgroup analysis of these data collected in the RECAP-DM study to indicate probably more emphasis and concern on hypoglycemia in type 2 diabetic patients in Taiwan. In this analysis, we found no significant difference was observed in treatment-related satisfaction between Taiwanese patients with or without hypoglycemia. Another finding of our study further shows that varying order of hypoglycemic symptoms or severity has no effect on patients' assessment of health-related quality of life scores. We need to pay more attention to this issue because of its enduring impact on compliance and concerns about hypoglycemia in type 2 diabetic patients. Nevertheless, socio-demographic characteristics are also important factors influencing glycemic control and patients' health-related quality of life. Future interventions and therapeutic algorithms should emphasize the probable patients' unawareness or neglect on hypoglycemia in diabetic patients.

Gender-Specific Variation in the Prognosis of Papillary Thyroid Cancer TNM Stages II to IV.

To investigate the correlation between gender and the clinical presentation of papillary thyroid cancer and the long-term followup results, 435 patients who underwent total or near-total thyroidectomy were enrolled in this study. Among these papillary thyroid cancer patients, 12.2% showed lymph node metastases and a higher incidence of male patients in the N1b group. There were 65 from 316 female (20.6%) and 49 from 120 male (40.8%) patients who had a postoperative disease progression. A total of 55 (12.6%) patients died of thyroid cancer. Male patients showed a higher thyroid cancer mortality than the females. Multiple regression analysis showed that male gender was an independent risk factor for cancer recurrence and mortality. Male patients with TNM stages II to IV of papillary thyroid cancer need to adopt aggressive surgical and postoperative (131)I therapy.

Risk factors for lower extremity amputation in diabetic foot disease categorized by Wagner classification.

AIMS: To elucidate the risk factors for lower extremity amputation (LEA) in patients of diabetic foot disease with different Wagner gradings. METHODS: This study was conducted in a multidisciplinary diabetic foot care center. Demographic characteristics, laboratory data, disease history, ankle brachial pressure index (ABI) and Wagner classification were considered as independent variables to predict the therapeutic outcome (major LEA, minor LEA, and non-amputation). Risk factors for LEA in different Wagner grades were further analyzed. Multivariate stepwise ordinal logistic regression was performed. RESULTS: Of 789 study subjects, 19.9% received major LEA and 22.9% received minor LEA. Higher Wagner grade, lower ABI, serum albumin and hemoglobin, and elevated white blood cell (WBC) count were significantly associated with an increased risk of LEA. When stratified by Wagner classification, most of the above predictors and estimated glomerular filtration (eGFR) were detected only in grade 3. While in grades 2 and 4, WBC count was identified as primary predictor positively associated with an increased risk of LEA. CONCLUSIONS: Wagner classification remarkably influenced the potential risk factors for LEA, showing different predictors in different grades. The traditionally recognized predictors for diabetic foot amputation such as lower ABI, albumin or eGFR were almost exclusively found in patients with Wagner grade 3.

Effects of a novel short-term continuous subcutaneous insulin infusion program evaluated by continuous glucose monitoring on young adult type 1 diabetic patients in Taiwan.

The aim of this study is to evaluate the effectiveness of blood sugar control by a short-course reinforcement program, consisting of using continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM) for young adult type 1 diabetic patients. Twenty-six pump-naïve type 1 diabetic patients were successively enrolled in two years. The mean disease duration was 13 years and the mean HbA1c was 8.8 %. Initially, a 3-day course of CGM was used to evaluate the baseline glycemic status of the subjects, followed by 6-day intensive insulin adjustment by CSII therapy. Thereafter, a second course of CGM was performed to evaluate the effectiveness of our outcomes in comparison to the initial measurements. All participants received necessary education and instruction as required throughout the course of the program. The glucose variability as measured by standard deviation of plasma glucose and mean amplitude of glucose excursion decreased significantly (67.8 ± 2.7 to 52.0 ± 1.8 mg/dL and 140.4 ± 6.5 to 105.5 ± 5.3 mg/dL, p < 0.001). The hypoglycemic events noted per patient were reduced by 46.4% (p = 0.003) and occurred significantly less often during nocturnal periods (-63.2%, p = 0.002). Following the adjustment, the mean daily insulin requirement was reduced by 28.05% (from 0.82 to 0.59 IU/kg) and the new proportion of 40% as basal insulin was found. The short-term CSII program provided significant improvement in blood sugar control for type 1 diabetic patients, by reducing hypoglycemic events, glucose excursion, and insulin dosage in our examined subjects.

Evaluation of the efficacy and tolerability of miglitol in Chinese patients with type 2 diabetes mellitus inadequately controlled by diet and sulfonylureas.

The objective of this study is to examine the efficacy and tolerability of miglitol with respect to improving glycemic control in Chinese patients with type 2 diabetes mellitus inadequately controlled by diet and sulfonylurea treatment. This was a randomized, double-blinded, placebo-controlled, multicenter study. A total of 105 patients were randomized to receive 24 weeks of treatment with miglitol (n = 52; titrated from 50 mg to 100 mg 3 times daily) or placebo (n = 53). Concomitant sulfonylurea treatment and diet remained unchanged. The primary endpoint was change in glycated hemoglobin (HbA1c) from baseline at 24 weeks. Secondary endpoints were changes in fasting plasma glucose (FPG), postprandial plasma glucose (PPG), and postprandial serum insulin (PSI). The miglitol treatment group showed significantly greater reductions in HbA1c and PPG levels compared with the placebo group. With respect to adverse events, abdominal discomfort, diarrhea, and hypoglycemia occurred with similar frequency in both groups. Results of this study indicate that miglitol significantly improves metabolic control in Chinese patients with type 2 diabetes mellitus. Miglitol is safe and well tolerated, with the exception of abdominal discomfort. Therefore, miglitol may be a useful adjuvant therapy for Chinese patients with type 2 diabetes mellitus inadequately controlled by diet and sulfonylurea treatment.

The cooperative phenomenon of autonomic nervous system in urine storage for Wistar rats.

The fractal dimension (FD) and spectral frequencies of physiological signals are two important indices in the study of physiological functions and dynamical diseases. The first index can be used to characterize the intensity and the second the rhythms of signals embedded in seemingly random data. Recent studies using both indices verified that synergic co-activations of bladder and external urethral sphincter (EUS) of Wistar rats were present during the voiding of urine. In this study, the primary aims were to (1) examine if the involved muscles in the lower urinary tract would be under similar coactivations during the urine storage phase, and (2) characterize quantitatively the sympathetic and parasympathetic nerve activities simultaneously. Eighteen experiments were performed on six intact adult female Wistar rats and then the electromyogram of EUS and cystometrogram of bladder were analyzed. Results indicated that the EUS did not contain any significant spectral frequencies in the storage phase. Furthermore, its FDs (1.5918 +/- 0.0157) indicated that no appreciable amount of signal intensities was observed in the EUS. On the other hand, the bladder exhibited parasympathetic frequency of 8 Hz with signal-to-noise ratio (SNR) = 19.9001 decibel (dB) for group mean, and sympathetic frequency of 19 Hz with SNR = 22.8330 dB for group mean. In addition, its FDs (1.4796 +/- 0.0092) indicated relatively persistent intensities during storage, as compared to that of EUS (1.5918 +/- 0.0157) with statistical significance (P < 0.01). We concluded that the EUS was not activated during the phase of storage. The bladder was under the cooperative, not antagonistic, sympathetic and parasympathetic nerve activities with discernible rhythmic frequencies and persistent intensities.
