Increased number of structured diabetes education attendance was not associated with the improvement in patient-reported health-related quality of life: results from Patient Empowerment Programme (PEP)
Aims: To assess the effect of a structured education intervention, Patient Empowerment Programme (PEP) patient-reported health-related quality of life (HRQOL) among type 2 diabetes mellitus (T2DM) patients, and if positive effect is confirmed, to further explore any association between frequency of sessions attendance and HRQOL. Methods: A total of 298 T2DM patients were recruited when they attended the first session of PEP, between March and September 2010, and were followed over a one-year period from baseline. HRQOL data were assessed using Short Form-12 Health Survey version 2 (SF-12) and Short Form-6 Dimension (SF-6D) at baseline and one-year follow-up. Individuals’ anthropometric and biomedical data were extracted from an administrative database in Hong Kong. Unadjusted and adjusted analyses of linear regression models were performed to examine the impact of PEP session attendance on the change in the HRQOL scores, accounting for the socio-demographic and clinical characteristics at baseline. Results: Of the 298 eligible patients, 257 (86.2 %) participated in the baseline assessment and 179 (60.1 %) patients completed the follow-up assessment, respectively. Overall, PEP resulted in a significant improvement in SF-12 bodily pain and role emotional subscales and SF-6D utility scores. These positive changes were not associated with the level of participation as shown in both unadjusted and adjusted analyses. Conclusions: The PEP made significant improvement in bodily pain, role emotional and overall aspects of HRQOL. Higher number of session attendance was not associated with improvement in HRQOL in primary care real-world setting.published_or_final_versio
Cost-effectiveness simulation and analysis of colorectal cancer screening in Hong Kong Chinese population: comparison amongst colonoscopy, guaiac and immunologic fecal occult blood testing
Background: The aim of this study was to evaluate the cost-effectiveness of CRC screening strategies from the healthcare service provider perspective based on Chinese population. Methods: A Markov model was constructed to compare the cost-effectiveness of recommended screening strategies including annual/biennial guaiac fecal occult blood testing (G-FOBT), annual/biennial immunologic FOBT (I-FOBT), and colonoscopy every 10 years in Chinese aged 50 year over a 25-year period. External validity of model was tested against data retrieved from published randomized controlled trials of G-FOBT. Recourse use data collected from Chinese subjects among staging of colorectal neoplasm were combined with published unit cost data (20,542/LYs and 19,838/LYs gained and 50,000 per LYs or QALYs gained. Conclusion: The Markov model informed the health policymakers that I-FOBT every year may be the most effective and cost-effective CRC screening strategy among recommended screening strategies, depending on the willingness-to-pay of mass screening for Chinese population.

Variation of microphysics in wind bubbles: an alternative mechanism for explaining the rebrightenings in Gamma-ray burst afterglows
Conventionally, long Gamma-ray bursts (GRBs) are thought to be caused by the core collapses of massive stars. During the lifetime of a massive star, a stellar wind bubble environment should be produced. Furthermore, the microphysics shock parameters may vary along with the evolution of the fireball. Here, we investigate the variation of the microphysics shock parameters under the condition of wind bubble environment, and allow the microphysics shock parameters to be discontinuous at shocks in the ambient medium. It is found that our model can acceptably reproduce the rebrightenings observed in GRB afterglows, at least in some cases. The effects of various model parameters on rebrightenings are investigated. The rebrightenings observed in both the R-band and X-ray afterglow light curves of GRB 060206, GRB 070311 and GRB 071010A are reproduced in this model. © 2009 The Authors.

Effect of a structured diabetes education programme in primary care on hospitalizations and emergency department visits among people with Type 2 diabetes mellitus: results from the Patient Empowerment Programme
AIM: To assess whether a structured diabetes education programme, the Patient Empowerment Programme, was associated with a lower rate of all-cause hospitalization and emergency department visits in a population-based cohort of patients with Type 2 diabetes mellitus in primary care. METHODS: A cohort of 24 250 patients was evaluated using a linked administrative database during 2009-2013. We selected 12 125 patients with Type 2 diabetes who had at least one Patient Empowerment Programme session attendance. Patients who did not participate in the Patient Empowerment Programme were matched one-to-one with patients who did, using the propensity score method. Hospitalization events and emergency department visits were the events of interest. Cox proportional hazard and negative binomial regressions were performed to estimate the hazard ratios for the initial event, and incidence rate ratios for the number of events. RESULTS: During a median 30.5 months of follow-up, participants in the Patient Empowerment Programme had a lower incidence of an initial hospitalization event (22.1 vs 25.2%; hazard ratio 0.879; P<0.001) and emergency department visit (40.5 vs 44%; hazard ratio 0.901; P<0.001) than those who did not participate in the Patient Empowerment Programme. Participation in the Patient Empowerment Programme was associated with a significantly lower number of emergency department visits (incidence rate ratio 0.903; P<0.001): 40.4 visits per 100 patients annually in those who did not participate in the Patient Empowerment Programme vs. 36.2 per 100 patients annually in those who did. There were significantly fewer hospitalization episodes (incidence rate ratio 0.854; P<0.001): 200 hospitalizations per 100 patients annually in those who did not participate in the Patient Empowerment Programme vs. 16.9 hospitalizations per 100 patients annually in those who did. CONCLUSIONS: Among patients with Type 2 diabetes, the Patient Empowerment Programme was shown to be effective in delaying the initial hospitalization event and in reducing their frequency.

Patient Empowerment Programme in primary care reduced all-cause mortality and cardiovascular diseases in patients with type 2 diabetes mellitus: a population-based propensity-matched cohort study
Aims: To assess whether a structured diabetes education programme, Patient Empowerment Programme (PEP), was associated with a lower risk of first cardiovascular disease (CVD) event and all-cause mortality in a population-based cohort of type 2 diabetes mellitus (T2DM) patients in primary care. Materials and Methods: A Chinese cohort of 27,278 T2DM patients without prior occurrence of CVD events on or before baseline study recruitment date was linked to the Hong Kong administrative database from 2008 to 2013. PEP was provided to T2DM patients treated at primary care outpatient clinics through community trained professional educators. Non-PEP participants were matched one-to-one with the PEP participants using propensity score method with respect to their baseline covariates. Cox proportional hazard regressions were performed to estimate the associations of PEP with the occurrence of first CVD event, coronary heart disease, stroke, heart failure and death from any cause, controlling for baseline characteristics. Results: During a median of 21.5 months follow-up, 795 (352 PEP participants and 443 non-PEP participants) patients suffered a first CVD event. After adjusting for confounding variables, PEP participants had a lower incidence of all-cause mortality (hazard ratio: 0.564; 95%CI:0.445-0.715; P < 0.001), first CVD (hazard ratio: 0.807; 95%CI:0.696-0.935; P = 0.004) and stroke (hazard ratio: 0.702; 95%CI:0.569-0.867; P = 0.001) events than those without PEP. Conclusions: Enrolment in PEP was associated with reduced all-cause mortality and first CVD events among T2DM patients. The CVD benefit of PEP might be attributable to improving metabolic control through empowerment of self-care and enhancement of quality of diabetes care in primary care.postprin
Left ventricular myocardial deformation and mechanical dyssynchrony in children with normal ventricular shortening fraction after anthracycline therapy
Objective: The M-mode-derived left ventricular shortening fraction is incorporated into most of the paediatric oncology protocols for monitoring of cardiotoxicity. This study tested the hypothesis that alteration of left ventricular myocardial deformation and mechanical dyssynchrony may occur in asymptomatic children after anthracycline therapy despite having left ventricular shortening fractions within the limits of normal. Design: Cross-sectional study. Setting: Tertiary paediatric cardiac centre. Methods: Left ventricular longitudinal, circumferential and radial myocardial deformation was determined using speckle tracking echocardiography in 45 patients aged 15.3±5.8 years. Real-time three-dimensional echocardiographic data were acquired for the measurement of left ventricular volumes and systolic dyssynchrony index (SDI), the latter derived from the dispersion of time-to-minimum regional volume using a 16-segment model. The results were compared with those of 44 controls. Results: Compared with controls, patients had reduced left ventricular global systolic longitudinal strain (p=0.012), circumferential strain (p4.96%) in patients was 16% (95% CI 6% to 29%). In patients, SDI correlated negatively with left ventricular ejection fraction (r=-0.52, p<0.001), radial strain (r=-0.35, p=0.021), circumferential strain (r=-0.37, p=0.015) and circumferential SR (r=-0.43, p=0.004), but not with the cumulative anthracycline dose (p=0.82). Conclusions: Impaired left ventricular myocardial deformation and mechanical dyssynchrony may exist in children after anthracycline therapy despite having normal left ventricular shortening fractions.published_or_final_versio
