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.

Association of Hemoglobin A1c Levels With Cardiovascular Disease and Mortality in Chinese Patients With Diabetes
LettersAmong diabetic patients, hemoglobin A1c (HbA1c) is an important indicator of glycemic control and, together with blood pressure and cholesterol, is an indicator for risk of complications, including cardiovascular disease (CVD) and mortality. At present, there is no universal consensus on the optimal HbA1c level. Despite this, most international guidelines include a recommended HbA1c target range or level as a treatment goal. Several studies have identified a J-shaped curvilinear relationship between HbA1c and CVD incidence and all-cause mortality, but such a relationship has not yet been confirmed in a Chinese population. There are substantial differences in disease risks across racial and ethnic groups due to genetic and environmental factors including life-style and health behaviors, and thus, previous results from Western studies may not be transferable to a Chinese population. We sought to examine the association among mean HbA1c, CVD events, and mortality among Chinese primary care patients with type 2 diabetes mellitus (T2DM) in Hong Kong.postprin

New two-dimensional global longitudinal strain and strain rate imaging for assessment of systemic right ventricular function
Objectives: To determine the usefulness of new two-dimensional strain indices, based on speckle tracking imaging, for assessment of systemic right ventricular (RV) function after an atrial switch operation for transposition of the great arteries. Design: Cross-sectional study. Setting: Tertiary paediatric cardiac centre. Methods: 26 patients, mean (SD) age 21.0 (3.6) years at 19.9 (3.2) years after an atrial switch operation, and 27 age-matched controls were studied. Two-dimensional imaging at the four-chamber view was obtained with tracing of the entire RV endocardial border. The RV global longitudinal strain (GLS) and GLS rate were derived using automated software (EchoPAC, GE Medical) and correlated with tissue Doppler-derived RV isovolumic acceleration (IVA), and, in the patient cohort, with cardiac magnetic resonance-derived RV ejection fraction. Results: Intra- and interobserver variability for measurement of GLS, as determined from the mean (SD) of differences in two consecutive results from 20 studies, were 0.06 (1.39)% and 0.24 (1.77)%, respectively. Compared with controls, patients had lower RV GLS (17.1 (1.9)% vs 26.3 (2.9)%, p<0.001), a reduced GLS rate (0.78 (0.11)/s vs 1.33 (0.23)/s, p<0.001), lower RV IVA (1.10 (0.36) m/s 2 vs 1.56 (0.53) m/s 2, p<0.001) and increased RV myocardial performance index (0.52 (0.09) vs 0.38 (0.09), p<0.001). Both RV GLS and GLS rate correlated positively with RV IVA (r = 0.43, p = 0.001 and r = 0.46, p<0.001, respectively), and negatively with RV myocardial performance index (r = -0.65, p<0.001 and r = -0.57, p<0.001, respectively). In patients, the GLS rate correlated positively with RV ejection fraction (r = 0.62, p = 0.001). Conclusions: Two-dimensional RV GLS and GLS rate are new, potentially useful indices for assessment of systemic RV function.published_or_final_versio
