We present the Greek population data of the study. METHODS: An observational multicenter, cross-sectional study evaluating glycaemic control and a range of other clinical and biological measures as well as quality of life(Qo L) and treatment satisfaction in 375 patients with T2 DM enrolled by 25 primary care sites from Greece. RESULTS: The mean age of the patients was 63.5 years and the male/female ratio 48.9%/51.1%. 79.7% of the patients exerted none or light physical activity, 82.4% were overweight or obese and 32.9% did not meet Hb A1 c target of less than 7.0%(53 mmol/mol). Patients reported high satisfaction to continue with treatment, high satisfaction with administered treatment and increased willingness to recommend treatment to others(mean Diabetes Treatment Satisfaction Questionnaire score 29.1 ± 5.6). However, 80% of the patients reported that their Qo L would be better without diabetes. Finally, the most challenging parameter reported was the lack of freedom to eat and drink. CONCLUSION: This analysis of the Greek Panorama study results showed that a considerable percentage of T2 DM patients in Greece do not achieve glycaemic target levels, despite the favourably reported patient satisfaction from administered therapy. Additionally, the majority of primary care T2 DM patients in Greece depict the negative effect of the disease in their Qo L. 展开更多

Objectives To study wheth- er change of BNP levels reflect the change of cardiac function and to investigate the short - term prognostic potential of BNP and QOL in patients with CHF. Methods 96 consecutive patients admittedwith CHF between September 2002 and January 2003 were stud- ied , upon entry the study, BNP levels were measured, Patients administered the disease - specificquality of life questionnaire Minnesota living with heart failure questionnaire (LiHFe) within 1 day. BNP levels and administering LiHFe were repeated three months later. Results BNP levels were increased proportional to the severity of cardiac function. Physical domain and total score of LiHFe were significantly correlated to the severity of CHF ( p < 0. 05 ). BNP levels were de- creased in improving group(p =0. 032) . In deteriora- ting group BNP levels increased (P = 0. 043 ) . Kaplan - meier analysis according to BNP level cutoff point 150 ng/1, the life curve of higher BNP level group was significantly lower than the lower group ( p = 0. 001 ) . In univariate logistic regression, NYHA class, BNP, LVEF, LVEDD, heart size, total score of LiHFe, phys- ical domain of LiHFe and the emotional domain of LiH- Fe were all significant prognostic factors of CHF ( p < 0. 05 for all). While in multiple regression, only BNP level( p = 0. 036) and the emotional domain of LiHFe ( p = 0. 025 ) were independent prognostic factors. Conclusions Change of BNP reflects the treatment efficacy of CHF. BNP and QOL are the two major short - time prognostic factors of the chronic heart failure patients. 展开更多

This paper proposes a simple constant-stress accel- erated life test (ALT) model from Burr type XII distribution when the data are Type-I progressively hybrid censored. The maximum likelihood estimation (MLE) of the parameters is obtained through the numerical method for solving the likelihood equations. Approxi- mate confidence interval (CI), based on normal approximation to the asymptotic distribution of MLE and percentile bootstrap Cl is derived. Finally, a numerical example is introduced and then a Monte Carlo simulation study is carried out to illustrate the pro- posed method. 展开更多

This study improved the application of the Holdridge life-zone model to simulate the distribution of desert vegetation in China which gives statistics to support eco-recovery and ecosystem reconstruction in desert area. This study classified the desert vegetation into four types: (1) LAD: little arbor desert; (2) SD: shrub desert: (3) HLHSD: half-shrub, little half-shrub desert; (4) LHSCD: little halfshrub cushion desert. Based on the classification of Xinjiang desert vegetation, the classical Holdridge life-zone model was used to simulate Xinjiang desert vegetation's distribution and compare the Kappa coefficient result of the model with table of accuracy represented by Kappa values. The Kappa value of the model was only 0.19, it means the simulation result was poor. To improve the life-zone model application to Xinjiang desert vegetation type, a set of plot standards for terrain factors was developed by using the plot standard as the reclassification criterion to climate sub-regime. Then the desert vegetation in Xinjiang was simulated. The average Kappa value of the second simulation to the respective climate regime was 0.45. The Kappa value of final modeling result was 0.64, which is the better value. The modification of the model made it in more application region. In the end, the model' s ecological relevance to the Xinjiang desert vegetation types was studied. 展开更多

Under Type-Ⅱ progressively hybrid censoring, this paper discusses statistical inference and optimal design on stepstress partially accelerated life test for hybrid system in presence of masked data. It is assumed that the lifetime of the component in hybrid systems follows independent and identical modified Weibull distributions. The maximum likelihood estimations(MLEs)of the unknown parameters, acceleration factor and reliability indexes are derived by using the Newton-Raphson algorithm. The asymptotic variance-covariance matrix and the approximate confidence intervals are obtained based on normal approximation to the asymptotic distribution of MLEs of model parameters. Moreover,two bootstrap confidence intervals are constructed by using the parametric bootstrap method. The optimal time of changing stress levels is determined under D-optimality and A-optimality criteria.Finally, the Monte Carlo simulation study is carried out to illustrate the proposed procedures. 展开更多

This was collaborative work of Baqai Institute of Diabetology and Endocrinology, World Diabetes Foundation and Baqai Medical University between February 2010 to February 2013. Under this project thirty-four T1D clinics were established. Electronic database was designed for demographic, biochemical, anthropometric and medical examination. Monthly consultation was part of the standardized diabetes care. All the recruited subjects with T1D were provided free insulins and related materials. RESULTS Out of 1428 subjects, 795 (55.7%) were males and 633 (44.3%) were females. Subjects were categorized into ≤ 5 years of age 103 (7.2%), between 6-12 years 323 (22.6%), between 13–18 years 428 (29.7%) and ≥ 19 years of age 574 (40.2%) groups. Glycemic control as assessed by HbA1c was significantly improved (P <0.0001) at three years follow up as compared to baseline in all age groups. Decreasing trends of mean self-monitoring blood glucose were observed at different meal timings in all age groups. No significant change was found in the frequency of neuropathy, nephropathy and retinopathy during the study period (P > 0.05). CONCLUSION This study gives us long-term longitudinal data of people with T1D in a resource constraint society. With provision of standardized and comprehensive care significant improvement in glycemic control without any change in the frequency of microvascular complications was observed over 3 years. 展开更多

AIM To unravel relationships between gastrointestinal(GI)symptoms impairing quality of life(QOL)and clinical profiles of diabetes mellitus(DM)patients. METHODS We enrolled 134 outpatients with type 2 DM.Mean age was 64.7 years,mean body mass index was 24.7 RESULTS Lower abdominal symptoms were found to be more frequent than those affecting the upper abdomen.Diabetic duration and medications showed associations with GI symptoms.We identified differences in peak prevalences of the five symptoms.Gastralgia(P=0.02vs 10-14 years)and total GI symptoms(P=0.01 and P=0.02 vs 5-9 years and 10-14 years,respectively)peaked at a diabetes duration of 15-19 years.Heartburn(P=0.004)and postprandial fullness(P=0.03)tended to increase with disease duration.Constipation and diarrhea showed bimodal peaks,with the first early and the second late(e.g.,P=0.03 at 15-19 years vs 10-14years for diarrhea)in the disease course.Finally,GI symptoms showed clustering that reflected the region of the GI tract affected,i.e.,constipation and diarrhea had similar frequencies(P<0.0001). CONCLUSION Our study highlights the importance of questioning patients about QOL impairment due to abdominal symptoms,especially in the early and the late periods of diabetes. 展开更多
