Newly diagnosed type 1 diabetes mellitus in a human immunodeficiency virus-infected patient with antiretroviral therapy-induced immune reconstitution inflammatory syndrome: a case report.

BACKGROUND: Diabetes that develops in human immunodeficiency virus (HIV)-infected patients who receive antiretroviral therapy (ART) is usually type 2 diabetes mellitus (T2DM); however, autoimmune diabetes, such as type 1 diabetes mellitus (T1DM) can also develop in this population. After treatment with ART, patients might experience clinical deterioration following an increase in the CD4 cell count, which is termed immune reconstitution inflammatory syndrome (IRIS). Here, we describe an HIV-infected patient on ART who developed T1DMat due to IRIS, highlighting the clinical complexity in diagnosis and treatment. CASE PRESENTATION: A 36-year-old man infected with HIV had a nadir CD4 cell count of 15.53/µL before medication, which increased to 429.09/µL after 9 months of regular ART. The fasting serum glucose at 9 months was between 96 mg/dL and 117 mg/dL. After 11 months of ART, the patient was admitted to hospital for diabetic ketoacidosis (DKA) and Graves' disease (GD). Noninsulin antidiabetics (NIADs) were prescribed following the resolution of DKA. However, poor glycemic control was noted despite well-titrated NIADs. Further investigation demonstrated poor pancreatic beta cell function and elevated anti-glutamic acid decarboxylase (anti-GAD) and anti-tyrosine phosphatase-like insulinoma antigen 2 (anti-IA2) titers. According to the results, he was diagnosed with T1DM and received multiple daily injections(MDI) of insulin. The regimen of MDI was insulin degludec as basal insulin and insulin aspart as prandial insulin. After MDI therapy, his glycemic control was improved. CONCLUSION: In this case, T1DM was ascribed to IRIS. Although this phenomenon has been demonstrated in previous case reports, further study is necessary to realize the mechanism of this association. Therefore, we emphasize that when HIV-infected patients on ART experience an unstable blood glucose level and abnormal thyroid function, physicians should consider T1DM and GD associated with ART-induced IRIS to reduce the subsequent complications and more serious endocrine dysfunction.

Expression of advanced glycation end products and receptors in gingival tissues of patients with noninsulin-dependent diabetes mellitus-associated periodontitis.

Background/purpose: Advanced glycation end products (AGEs) are known to accumulate in the periodontal tissues of patients with diabetes mellitus (DM). Through this study, we aimed to investigate the distribution of AGEs and the receptor of AGEs (RAGE) in the gingival tissues of patients with chronic periodontitis with and without non-insulin-dependent diabetes mellitus (NIDDM). Materials and methods: Gingival biopsy samples from 13 patients with both NIDDM and periodontitis and 6 patients with both non-DM (NDM) and periodontitis were collected. The tissue sections were processed using immunohistochemical (IHC) staining to detect the distributions of AGEs and RAGE. Spearman correlation coefficients of all samples were calculated (P < 0.05) for the AGE and RAGE rankings of the following clinical parameters: plaque score (PI), probing depth (PD), bleeding on probing (BOP), and tooth loss (TL). Results: IHC analysis revealed that AGEs among patients with NIDDM had a significantly higher ranking than those of the NDM group (P < 0.05). Positive staining for RAGE was observed in both groups but was not significantly different (P > 0.05). A positive correlation between AGE ranking and TL was observed in the NIDDM group, but not between AGE ranking and PI, PD, or BOP. The distribution of RAGE was not correlated with PI, PD, BOP, or TL. Conclusion: AGEs were particularly distributed in the highly inflamed gingiva of patients with NIDDM-associated periodontitis and was statistically correlated with the long-term parameter TL.

Effect of metformin monotherapy and dual or triple concomitant therapy with metformin on glycemic control and lipid profile management of patients with type 2 diabetes mellitus.

Background: In this study, we aimed to compare the effects of metformin-based dual therapy versus triple therapy on glycemic control and lipid profile changes in Taiwanese patients with type 2 diabetes mellitus (T2DM). Methods: In total, 60 patients were eligible for participation in this study. Patients received at least 24 months of metformin monotherapy, dual therapy, or triple therapy with metformin plus linagliptin (a dipeptidyl peptidase 4 (DPP-4) inhibitor) or dapagliflozin (a sodium-glucose cotransporter-2 (SGLT2) inhibitor). Blood samples were collected from each patient, followed by evaluation of changes in their blood glucose control and lipid profile-related markers. Results: A combination of metformin and DPP4 and SGLT2 inhibitor therapy more effectively reduced low-density lipoprotein cholesterol (LDL-C) (p = 0.016) than metformin monotherapy. A combination of metformin and DPP4 and SGLT2 inhibitor therapy more effectively improved total cholesterol (Chol, p = 0.049) and high-density lipoprotein cholesterol (HDL-C) than metformin monotherapy (p = 0.037). Metformin plus linagliptin dual therapy was more effective than metformin monotherapy in reducing glycosylated hemoglobin (HbA1C, p = 0.011). Patients who received a combination of linagliptin and empagliflozin showed a significant reduction in their fasting blood glucose (p = 0.019), HbA1c (p = 0.036), and Chol (p = 0.010) compared with those who received linagliptin dual therapy. Furthermore, patients who received metformin plus dapagliflozin and saxagliptin showed significantly reduced Chol (p = 0.011) and LDL-C (p = 0.035) levels compared with those who received metformin plus dapagliflozin. Conclusion: In conclusion, dual therapy with metformin and linagliptin yields similar glycemic control ability to triple therapy. Among metformin combination triple therapy, triple therapy of empagliflozin and linagliptin might have a better glycemic control ability than dual therapy of linagliptin. Moreover, Triple therapy of dapagliflozin and saxagliptin might have a better lipid control ability than dual therapy of dapagliflozin.

Clinical significance of hepatic function in Graves disease with type 2 diabetic mellitus: A single-center retrospective cross-sectional study in Taiwan.

Graves disease (GD) and type 2 diabetes mellitus (T2DM) both impair liver function; we therefore explored the possibility of a relationship among diabetic control, thyroid function, and liver function. This retrospective, cross-sectional study compared serum liver function biomarkers of primary GD patients in a single center between 2016 and 2020, derived from clinical databases, and clarified the correlation of liver function in GD patients with or without T2DM. Furthermore, the diabetes mellitus group was divided into glycated hemoglobin A1C (HbA1C) <6.5% group and ≥6.5% group to further analyze the effect by disease control in patients. Statistical differences between groups were assessed using independent t tests to clarify the association of serum biomarkers between GD with T2DM. Pearson test was applied to assess within-group statistical correlation of serum biomarkers. The correlation of factors in each group was demonstrated by using the Kendall tau-b method and stepwise regression analysis. A total of 77 patients were included in the study. In the study population, glutamate pyruvate transaminase (GPT) was significantly correlated with thyroid-stimulating hormone, and HbA1C was significantly correlated with alkaline phosphatase (ALK-P), glutamate oxaloacetate transaminase (GOT), and GPT. An examination of GOT, GPT, free thyroxine (FT4), and HbA1C levels revealed a significant difference between the non-T2DM and T2DM groups. GPT also exhibited a significant correlation with triiodothyronine in the T2DM group. The T2DM group was further divided into groups: HbA1C <6.5% and ≥6.5%. The results demonstrated that ALK-P, GOT, GPT, and FT4 levels were significantly different between the groups. A significant correlation between ALK-P and thyroid-stimulating hormone and between GOT and FT4 was also identified in the HbA1C <6.5% group. Our single-center study revealed that diabetes affects liver function in patients with GD. For patients with T2DM, when liver function becomes impaired, thyroid function control deteriorates. GPT was correlated with triiodothyronine but not with FT4, which indicated the impairment of deiodination in the liver. This phenomenon was not observed in the non-T2DM population. The early detection of abnormal liver function in patients with GD and T2DM may help limit the development of comorbidities and improve disease management.

Voice-based control system for smart hospital wards: a pilot study of patient acceptance.

BACKGROUND: The smart hospital's concept of using the Internet of Things (IoT) to reduce human resources demand has become more popular in the aging society. OBJECTIVE: To implement the voice smart care (VSC) system in hospital wards and explore patient acceptance via the Technology Acceptance Model (TAM). METHODS: A structured questionnaire based on TAM was developed and validated as a research tool. Only the patients hospitalized in the VSC wards and who used it for more than two days were invited to fill the questionnaire. Statistical variables were analyzed using SPSS version 24.0. A total of 30 valid questionnaires were finally obtained after excluding two incomplete questionnaires. Cronbach's α values for all study constructs were above 0.84. RESULT: We observed that perceived ease of use on perceived usefulness, perceived usefulness on user satisfaction and attitude toward using, and attitude toward using on behavioral intention to use had statistical significance (p < .01), respectively. CONCLUSION: We have successfully developed the VSC system in a Taiwanese academic medical center. Our study indicated that perceived usefulness was a crucial factor, which means the system function should precisely meet the patients' demands. Additionally, a clever system design is important since perceived ease of use positively affects perceived usefulness. The insight generated from this study could be beneficial to hospitals when implementing similar systems to their wards.

Is the level of serum lactate dehydrogenase a potential biomarker for glucose monitoring with type 2 diabetes mellitus?

Introduction: Type 2 diabetes mellitus (T2DM) is a metabolic disorder due to defects in insulin secretion or insulin resistance leading to the dysfunction and damage of various organs. To improve the clinical evaluation of short-term blood glycemic variability monitoring, it is critical to identify another blood cell status and nutritional status biomarker that is less susceptible to interference. This study identifies the significance of serum lactate dehydrogenase (LDH) level among T2DM patients treated in outpatient clinics and investigates the relationship of LDH level with other variables. Methods: This study comprised 72 outpatients with T2DM over 20 years of age. Blood samples were collected followed by a hematological analysis of serum glycated albumin (GA), LDH, fasting blood glucose, glycosylated hemoglobin, C-peptide, and insulin antibodies (insulin Ab). Results: Serum LDH level was significantly correlated with GA (p < 0.001), C-peptide (p = 0.04), insulin Ab (p = 0.03), and thyroid-stimulating hormone (TSH) levels (p = 0.04). Hence, we performed a linear regression analysis of hematological markers. GA (p < 0.001, r2 = 0.45) and insulin Ab (p < 0.001, r2 = 0.40) were significantly associated with LDH level. Then, we classified patients into low (<200 U/L) and high (≥200 U/L) serum LDH level groups, respectively. GA (p < 0.001), C-peptide (p = 0.001), and TSH (p = 0.03) showed significant differences in patients with high LDH levels compared with those in patients with low LDH levels. Conclusion: In conclusion, we suggested that LDH level was independent of long-term but associated with short-term blood glucose monitoring. The results indicated that changes in serum GA induced cell damage and the abnormal elevation of the serum level of LDH may occur simultaneously with glycemic variability. It has been reported that many biomarkers are being used to observe glucose variability in T2DM. However, LDH could provide a more convenient and faster evaluation of glycemic variability in T2DM.

Skeletal Muscle Ratio: A Complete Mediator of Physical Activity and HbA1C in Type 2 Diabetes.

BACKGROUND: An increase in the physical activity level reduces body weight, decreases body fat, increases skeletal muscle mass, and improves serum glucose; however, the influence of body composition parameters on the relationship between physical activity and serum glucose remains unclear. OBJECTIVE: This study investigated whether skeletal muscle and visceral fat affect the relationship between high physical activity and long-term serum glucose goals. METHOD: This cross-sectional study recruited patients with type 2 diabetes. The Chinese version of the International Physical Activity Questionnaire was used for estimating the physical activity level, and a bioimpedance device was used to measure the skeletal muscle ratio (skeletal muscle mass/total body weight, %) and visceral fat area (cm2). Hierarchical logistic regression models and mediation tests were conducted according to Hayes' procedures. RESULTS: Of the total 543 Chinese individuals with type 2 diabetes enrolled, HbA1C levels of fewer than half (n = 243, 44.8%) met the target of ≤7.0%. The skeletal muscle ratio was found to be a complete mediator (OR = 0.920, 95% CI: 0.848 to 0.998; indirect effect: -0.238, 95% CI: -0.525 to -0.020) of the relationship between high physical activity and the target HbA1C level after controlling for visceral fat area (indirect effect: -0.013, 95% CI: -0.183 to 0.156), age, time since diabetes diagnosis, and rice intake. CONCLUSION: Nurses should include an increase in the skeletal muscle ratio as an objective in physical activity interventions for patients with type 2 diabetes to help them achieve their long-term serum glucose goals.

Incidences of Hypothyroidism Associated With Surgical Procedures for Thyroid Disorders: A Nationwide Population-Based Study.

Background and Aim: Limited information available about different types of thyroid surgeries with risk for postoperative hypothyroidism. This study aimed to investigate the risk of developing early and late-onset postoperative hypothyroidism in patients with thyroid disorders. Methods: We used a large cohort data from the Taiwan National Health Insurance Research Data Base (NHIRDB) and identified 9,693 (9, 348) patients from January 1998 to December 2010, admitted for thyroid disorder surgeries. We used the surgical procedures time as the index date. Our observational retrospective cohort study excluded the subjects diagnosed with hypoparathyroidism and hypothyroidism before any surgeries. We analyzed the data using the Cox regression model to calculate the hazard ratio. Result: Postoperative hypothyroidism associated with bilateral-total (HR, 4.27; 95% CI, 3.32-5.50), one-side total and another subtotal (HR, 3.16; 95% CI, 2.59-3.86), bilateral-subtotal (HR, 1.65; 95% CI, 1.37-1.98), and unilateral-total (HR, 1.17; 95% CI, 0.95-1.44) surgical procedures. The time intervals for thyroid disorders were 320 cases developed postoperative hypoparathyroidism in eight weeks, 480 cases the second month, and 1000 cases in the first year after surgery. Conclusion: Findings suggest that thyroidectomy was associated with transient postoperative hypothyroidism in thyroid disorder patients. The bilateral-total surgical procedure was strongly associated with temporary postoperative hypothyroidism.

The impact of different surgical procedures on hypoparathyroidism after thyroidectomy: A population-based study.

The main objective of this study is to investigate the outcome between surgical procedures and the risk of development of hypoparathyroidism followed by surgical procedure in patients with thyroid disorders.We analyzed the data acquired from Taiwan's Bureau of National Health Insurance (BNHI) research database from 1998 to 2011 and found 9316 patients with thyroid surgery. Cox regression model was used to calculate the hazard ratio (HR).A count of 314 cases (3.4%) of hypoparathyroidism was identified. The 9 years cumulated incidence of hypoparathyroidism was the highest in patient undergone bilateral total thyroidectomy (13.5%) and the lowest in the patient with unilateral subtotal thyroidectomy (1.2%). However, in the patients who had undergone unilateral subtotal, the risk was the highest in bilateral total (HR: 11.86), followed by radical thyroidectomy with unilateral neck lymph node dissection (HR: 8.56), unilateral total (HR, 4.39), and one side total and another side subtotal (HR: 2.80).The extent of thyroid resection determined the risk of development of hypoparathyroidism. It is suggested that the association of these factors is investigated in future studies.

Almonds ameliorate glycemic control in Chinese patients with better controlled type 2 diabetes: a randomized, crossover, controlled feeding trial.

BACKGROUND: Almonds can decrease glycemic index of co-consumed foods and are a rich source for oleic acid and α-tocopherol. The aim of the randomized, crossover, controlled feeding trial was to examine whether as compared to NCEP step II diet as control (CON), ~60 g/d almonds (ALM) added to CON would improve glucoregulation and cardiovascular disease (CVD) risk factors in 33 Chinese T2DM patients. METHODS: Forty T2DM patients were enrolled and randomly assigned to receive CON or ALM for 12 wks after a 2-wk. run-in period. Blood and urine samples were collected in the beginning and at the end of each dietary intervention phase for the assessment of biomarkers of glucoregulation, lipid profile, inflammation, and oxidative stress. RESULTS: While ALM had a better overall nutritional quality than CON, neither ALM nor CON improved the glycemic status as the primary study outcome and other CVD risk factors, except the circulating nitric oxide being decreased by ALM compared to CON. Among 27 of 33 patients with the baseline HbA1c ≤8, ALM decreased post-interventional fasting serum glucose and HbA1c by 5.9% and 3.0% as compared to that of CON, respectively (P = 0.01 and 0.04). Mean total and LDL-cholesterol concentrations were not changed by both diets. CONCLUSIONS: These results suggest almonds incorporated into healthful diets can improve glycemic status in diabetic patients with a better glycemic control. TRIAL REGISTRATION: NCT01656850, registered 13 January 2012.

The Concomitant Association of Thyroid Disorders and Myasthenia Gravis.

BACKGROUND: Some of the thyroid disorders (TD) and Myasthenia gravis (MG) are autoimmune related disease. The purpose of the study to evaluate the relationship of MG with all morphological and functional thyroid disorders. METHODS: We constructed a population-based cohort study during the period from January 2000-December 2002 by using reimbursement data from the Bureau National Health Insurance (NHI) system in Taiwan. Patients with TD and MG were identified by referring to the ICD-9-CM codes. (ICD-10-CM as reference) .The association of TD with MG occurred only in the same person within the study period. The Q value was used to measure the strength of disease-disease associations. RESULTS: We obtained 520628 TD and 7965 MG records for analysis. Diffuse toxic goiter had highest association rate, followed by nontoxic nodular goiter, simple goiter, chronic lymphocytic thyroiditis, thyroid cancer, and toxic nodular goiter. Female and older patients had a higher rate than their male and younger counterparts, respectively. Functional abnormalities revealed higher incidence of thyrotoxicosis and hypothyroidism in both sexes. We also found the strongest association in men with chronic thyroiditis, diffuse toxic goiter, thyrotoxicosis, acquired hypothyroidism, thyroid cancer, and simple goiter. While an intermediate association was observed in female with diffuse toxic goiter, in a male with toxic and nontoxic nodular/multinodular goiters, in female with thyrotoxicosis, thyroid cancer and acquired hypothyroidism. CONCLUSION: This population based cohort study showed potential association of all types of TD with MG, and observed a higher association rate in female autoimmune TD whereas males showed a higher strength of association.

Alternative health eating index and the Dietary Guidelines from American Diabetes Association both may reduce the risk of cardiovascular disease in type 2 diabetes patients.

BACKGROUND: In the general population, a higher Alternate Healthy Eating Index (AHEI)-2010 score is related to decreased cardiovascular disease (CVD) risk. Few studies have described the dietary patterns that reduce the risk of CVD or coronary heart disease (CHD) in type 2 diabetes mellitus (T2DM) patients. In the present study, the association between the American Diabetes Association (ADA)-recommended dietary pattern, AHEI-2010 , and CVD risk factors and the CVD incidence over 52 months in T2DM patients was evaluated. METHODS: The ADA score was developed from the ADA dietary recommendations. In this prospective study, the 24-h dietary recall of 124 adult T2DM patients without nephropathy or chronic kidney disease was collected. The CVD risk factors were collected at baseline and at 6-month follow-up. RESULTS: Compared with lower ADA and AHEI-2010 score participants, the higher score participants exhibited a significantly lower waist circumference, serum low-density lipoprotein cholesterol level and 10-year risk of CHD. Participants with higher ADA dietary scores had a significantly reduced risk of central obesity and systolic blood pressure >140 mmHg. Higher AHEI-2010 scores were significantly related to a reduced risk of serum low-density lipoprotein cholesterol > 100 mg dL(-1) . Seven participants had their first-ever CVD during the follow-up period, although neither ADA score, nor AHEI-2010 score could predict CVD incidence. CONCLUSIONS: The ADA-recommended dietary pattern and a higher AHEI-2010 score might both exhibit reduced risk factors of CVD in T2DM patients.

Using hemoglobin A1C as a predicting model for time interval from pre-diabetes progressing to diabetes.

OBJECTIVE: The early identification of subjects at high risk for diabetes is essential, thus, random rather than fasting plasma glucose is more useful. We aim to evaluate the time interval between pre-diabetes to diabetes with anti-diabetic drugs by using HbA1C as a diagnostic tool, and predicting it using a mathematic model. METHODS: We used the Taipei Medical University Affiliated Hospital Patient Profile Database (AHPPD) from January-2007 to June-2011. The patients who progressed and were prescribed anti-diabetic drugs were selected from AHPPD. The mathematical model used to predict the time interval of HbA1C value ranged from 5.7% to 6.5% for diabetes progression. RESULTS: We predicted an average overall time interval for all participants in between 5.7% to 6.5% during a total of 907 days (standard error, 103 days). For each group found among 5.7% to 6.5% we determined 1169.3 days for the low risk group (i.e. 3.2 years), 1080.5 days (i.e. 2.96 years) for the increased risk group and 729.4 days (i.e. 1.99 years) for the diabetes group. This indicates the patients will take an average of 2.49 years to reach 6.5%. CONCLUSION: This prediction model is very useful to help prioritize the diagnosis at an early stage for targeting individuals with risk of diabetes. Using patients' HbA1C before anti-diabetes drugs are used we predicted the time interval from pre-diabetes progression to diabetes is 2.49 years without any influence of age and gender. Additional studies are needed to support this model for a long term prediction.

How did national life expectation related to school years in developing countries - an approach using panel data mining.

BACKGROUND: The purpose of the study was to probe into the changes in life expectancy associated with schooling years found by the Organization for Economic Co-operation and Development (OECD). METHODS: The study was based on the OECD database from the period 2000 to 2006. The data of thirty countries were constructed to allow comparisons over time and across these countries. Panel data analysis was used to estimate the relationship of national education, as defined as school years, with life expectancy. The control factors considered were numbers of practicing physicians, practicing nurses, hospital beds, and GDP. RESULTS: We used fixed effects of both country and time through linear regression, the coefficient of school years in relation to life expectancy was statistically significant but negative. This finding is not in accord with the hypothesis that investing in human capital through education stimulates better health outcomes. CONCLUSION: Within developing countries, educational attainment is no longer keeping the same pace with life expectancy as before. Therefore, we suggest that an effective education policy should cover diverse topics, for example, balancing economic growth and mental hygiene, to improve national life expectancy.

A probabilistic model for reducing medication errors.

BACKGROUND: Medication errors are common, life threatening, costly but preventable. Information technology and automated systems are highly efficient for preventing medication errors and therefore widely employed in hospital settings. The aim of this study was to construct a probabilistic model that can reduce medication errors by identifying uncommon or rare associations between medications and diseases. METHODS AND FINDINGS: Association rules of mining techniques are utilized for 103.5 million prescriptions from Taiwan's National Health Insurance database. The dataset included 204.5 million diagnoses with ICD9-CM codes and 347.7 million medications by using ATC codes. Disease-Medication (DM) and Medication-Medication (MM) associations were computed by their co-occurrence and associations' strength were measured by the interestingness or lift values which were being referred as Q values. The DMQs and MMQs were used to develop the AOP model to predict the appropriateness of a given prescription. Validation of this model was done by comparing the results of evaluation performed by the AOP model and verified by human experts. The results showed 96% accuracy for appropriate and 45% accuracy for inappropriate prescriptions, with a sensitivity and specificity of 75.9% and 89.5%, respectively. CONCLUSIONS: We successfully developed the AOP model as an efficient tool for automatic identification of uncommon or rare associations between disease-medication and medication-medication in prescriptions. The AOP model helps to reduce medication errors by alerting physicians, improving the patients' safety and the overall quality of care.

Influenza vaccination and reduction in risk of ischemic heart disease among chronic obstructive pulmonary elderly.

COPD estimates the third leading cause of death by 2020. To reduce its complications becomes an important issue. The purpose of this study is to investigate the influenza vaccine effect for IHD occurrence with secondary to COPD. We used 11 years Taiwan National Health Insurance cohort research database and analyzed the relationships between vaccination and incident of IHD for COPD patients stratified by age. Total 29,178 COPD patients, 703 patients got vaccination out of 1464 who have developed IHD and 6010 patients vaccinated out of 27,714 that did not developed IHD. Major findings we observed: vaccination was associated with a reduced risk of IHD (OR, 0.746; 95% CI, 0.595-0.937) in elderly COPD patients. Influenza vaccination was associated with a reduced risk for IHD only in elderly COPD patients. Moreover, COPD patients with IHD had higher vaccination rate than without IHD.

A multidisciplinary diabetic foot ulcer treatment programme significantly improved the outcome in patients with infected diabetic foot ulcers.

BACKGROUND: Diabetic foot ulcers (DFUs) superimposed by infection and ischaemia may result in amputation without prompt and adequate management. We investigated whether the diabetic foot ulcer treatment programme (DFUTP) involving immediate debridement within 12 h, flap coverage and/or revascularisation improved the outcome of patients with infected DFUs. METHOD: Between 2006 and 2009, we randomly enrolled 350 patients in the DFUTP group and compared them with control patients (the non-DFUTP group, n = 386) in Taiwan. Inclusion criteria consisted of infected diabetic foot ulcers with or without ischaemia. The risk factors, dynamics and outcome of amputation and re-amputation were analysed in terms of patient demographics, glycaemic control and infection. RESULT: The results of logistic regression analyses indicated that risk factors of amputation in both groups were HbA1c (odds ratio (OR) = 1.63, 95% confidence interval (CI) 1.31-2.02) and C reactive protein (OR = 1.12, 95% CI 1.01-1.24). The DFUTP group showed a lower amputation rate than the non-DFUTP group (p = 0.001). The association between the amputation and University of Texas (UT) classification was not statistically significant. The Kaplan-Meier estimate showed that the time to complete recovery of the sugar level in the DFUTP group was faster than in the non-DFUTP group (p = 0.001). For patients at stage D, the hospital stay in the non-DFUTP group was longer than in the DFUTP group (p = 0.014). CONCLUSION: The DFUTP provides an effective treatment programme for decreasing the amputation rate with infected DFUs. Immediate debridement and flap reconstruction decrease the amputation and re-amputation rate respectively.

Preprandial single oral dose of sitagliptin does not affect circulating ghrelin and gastrin levels in normal subjects.

AIMS: To determine the effect of an oral dose of sitagliptin on the secretion of ghrelin and gastrin hormones. METHODS: Ten healthy volunteers were recruited in this study. A baseline blood sample was drawn before oral dosing with a 100-mg tablet of sitagliptin. Two blood samples were obtained 0.5 and 1 h after dosing. Three additional postprandial blood samples were drawn at 0.5, 1, and 2 h. Radioimmunoassay was used for determining hormonal levels. A Student's t test, Pearson correlation analysis, and multivariate approach to repeated-measures analysis of variance were used for statistics. RESULTS: After sitagliptin dosing, but before the meal, there was no significant change in circulating ghrelin, gastrin, insulin, and glucose levels. Only after meal loading was there a progressive and persistent decline in ghrelin levels until the end of the study, while a rapid and temporary rise in gastrin, insulin, and glucose levels at 0.5 h was observed. The levels of gastrin, insulin, and glucose then declined progressively. CONCLUSIONS: Preprandial oral dose of sitagliptin does not affect circulating ghrelin, gastrin, insulin, and glucose concentrations in normal subjects. Decreased ghrelin and increased gastrin and insulin levels occurred only after meal loading. These results support the theory that sitagliptin might not cause appetite-enhanced body weight gain and insulin-induced hypoglycemia.

Ameliorative effects of stabilized rice bran on type 2 diabetes patients.

BACKGROUND/AIM: While it has been demonstrated that rice bran might lower the cholesterol level in hypercholesterolemic individuals, its effects on the levels of adiponectin and glycated hemoglobin (HbA1c) in patients with type 2 diabetes mellitus remain unknown. METHODS: Twenty-eight volunteers with type 2 diabetes were randomly divided into 2 groups, one of which received a dietary supplement of 20 g of stabilized rice bran and the other placebo once daily for 12 weeks. Parameters such as the level of HbA1c, glucose, insulin, homeostasis model assessment for estimation of relative insulin resistance, high-density and low-density lipoprotein (LDL) cholesterol and adiponectin were evaluated. RESULTS: At the end of the study period, postprandial glucose and the area under the glucose curve of the rice bran group were significantly lower than baseline levels by 14.4 and 15.7%, respectively. Compared to baseline, the HbA1c values in the rice bran group were also significantly lower. Serum total cholesterol and LDL cholesterol concentrations in the rice bran group were 9.2 and 13.7% lower, respectively, than in the placebo group. The plasma free fatty acid and adiponectin concentrations were 20% lower and 40% higher in the rice bran group compared to the placebo group. CONCLUSIONS: This study demonstrated that stabilized rice bran can lower the level of HbA1c and blood lipids and increase blood adiponectin concentrations in type 2 diabetic subjects. In light of this, we conclude that stabilized rice bran may represent an important functional nutrient to ameliorate lipid and glycemic anomalies in type 2 diabetic subjects.

Effects of sulfonylureas on left ventricular mass in type 2 diabetic patients.

Myocardial ATP-sensitive potassium (K(ATP)) channels have been implicated in attenuating cardiac hypertrophy by modulating endothelin-1 concentrations. Sulfonylureas differ in their affinity for cardiac K(ATP) channels and therefore may vary in their effects on left ventricular (LV) mass. We sought to determine the differential effects of sulfonylureas on LV mass in type 2 diabetic patients. All patients had been taking glibenclamide for more than 3 mo before being randomized to either switch to an equipotent dose of gliclazide or continue glibenclamide. A total of consecutive 240 diabetic patients were randomized into glibenclamide, gliclazide, a combination of glibenclamide and nicorandil, or gliclazide and nicorandil for 6 mo. In the gliclazide-treated group, the LV mass index was significantly decreased compared with that in the glibenclamide-treated groups. Nicorandil administration significantly reduced LV mass in glibenclamide-treated patients compared with patients treated with glibenclamide alone. Measurements of endothelin-1 concentrations mirrored the functional status of K(ATP) channel. Multivariate analysis revealed that regression of LV mass was significantly correlated only with the changes in endothelin-1 (P < 0.0001). Our results show that K(ATP) channels may play a pathogenetic role, probably through an endothelin-1-dependent pathway, in diabetes mellitus-related ventricular hypertrophy. Patients treated with gliclazide may have a beneficial effect in attenuating ventricular mass.
